The 2000s (pronounced "two-thousands"; shortened to the '00s and known as the aughts or noughties) was a decade that began on January 1, 2000, and ended on December 31, 2009.

The early part of the decade saw the long-predicted breakthrough of economic giants in Asia, like India and China, which had double-digit growth during nearly the whole decade. It is also benefited from an economic boom, which saw the two most populous countries becoming an increasingly dominant economic force. The rapid catching-up of emerging economies with developed countries sparked some protectionist tensions during the period and was partly responsible for an increase in energy and food prices at the end of the decade. The economic developments in the latter third of the decade were dominated by a worldwide economic downturn, which started with the crisis in housing and credit in the United States in late 2007 and led to the bankruptcy of major banks and other financial institutions. The outbreak of this global financial crisis sparked a global recession, beginning in the United States and affecting most of the industrialized world.

The decade saw the rise of the Internet, which grew from covering 6.7% to 25.7% of the world population. This contributed to globalization during the decade, which allowed faster communication among people around the world;^{[1][2][3][4][5]} social networking sites arose as a new way for people to stay in touch from distant locations, as long as they had internet access. Myspace was the most popular social networking website until June 2009, when Facebook overtook it in number of American users. Email continued to be popular throughout the decade and began to replace "snail mail" as the primary way of sending letters and other messages to people in distant locations. Google, YouTube, Ask.com and Wikipedia emerged to become among the top 10 most popular websites. Amazon overtook eBay as the most-visited e-commerce site in 2008. AOL significantly declined in popularity throughout the decade, falling from being the most popular website to no longer being within the top 10. Excite and Lycos fell outside the top 10, and MSN fell from the second to sixth most popular site, though it quadrupled its monthly visits. Yahoo! maintained relatively stable popularity, remaining the most popular website for most of the decade.

The war on terror and War in Afghanistan began after the September 11 attacks in 2001. The International Criminal Court was formed in 2002. In 2003, a United States-led coalition invaded Iraq, and the Iraq War led to the end of Saddam Hussein's rule as Iraqi President and the Ba'ath Party in Iraq. Al-Qaeda and affiliated Islamist militant groups performed terrorist acts throughout the decade. The Second Congo War, the deadliest conflict since World War II, ended in July 2003. Further wars that ended included the Algerian Civil War, the Angolan Civil War, the Sierra Leone Civil War, the Second Liberian Civil War, the Nepalese Civil War, and the Sri Lankan Civil War. Wars that began included the conflict in the Niger Delta, the Houthi insurgency, and the Mexican drug war.

Climate change and global warming became common concerns in the 2000s. Prediction tools made significant progress during the decade, UN-sponsored organizations such as the IPCC gained influence, and studies such as the Stern Review influenced public support for paying the political and economic costs of countering climate change. The global temperature kept climbing during the decade. In December 2009, the World Meteorological Organization (WMO) announced that the 2000s may have been the warmest decade since records began in 1850, with four of the five warmest years since 1850 having occurred in this decade. The WMO's findings were later echoed by the NASA and the NOAA. Major natural disasters included Cyclone Nargis in 2008 and earthquakes in Pakistan and China in 2005 and 2008, respectively. The deadliest natural disaster^[a] and most powerful earthquake of the 21st century occurred in 2004 when a 9.1–9.3 M_w earthquake and its subsequent tsunami struck multiple nations in the Indian Ocean, killing 230,000 people.^[6]

Usage of computer-generated imagery became more widespread in films produced during the 2000s, especially with the success of 2001's Shrek and 2003's Finding Nemo, the latter becoming the best-selling DVD of all time. Anime films gained more exposure outside Japan with the release of Spirited Away. 2009's Avatar became the highest-grossing film. Documentary and mockumentary films, such as March of the Penguins, Super Size Me, Borat and Surf's Up, were popular in the 2000s. 2004's Fahrenheit 9/11 by Michael Moore was the highest grossing documentary of all time. Online films became popular, and conversion to digital cinema started. Video game consoles released in this decade included the PlayStation 2, Xbox, GameCube, Wii, PlayStation 3 and Xbox 360; while portable video game consoles included the Game Boy Advance, Nintendo DS and PlayStation Portable. Wii Sports was the decade's best-selling console video game, while New Super Mario Bros. was the decade's best-selling portable video game. J. K. Rowling was the best-selling author in the decade overall thanks to the Harry Potter book series, although she did not pen the best-selling individual book, being second to The Da Vinci Code.^[7] Eminem was named the music artist of the decade by Billboard.

During this decade, the world population grew from 6.1 to 6.9 billion people. Approximately 1.35 billion people were born, and 550 million people died.^[8]

Orthographically, the decade can be written as the "2000s" or the "'00s". In the English-speaking world, a name for the decade wasn't immediately accepted as it had been for other decades such as the 1980s and 1990s ('80s, '90s).^{[9][10][11][12][13]}

The aughts (American English)^[14][15][16] or noughties (British English)^[17][18] arise from the words aught and nought respectively, both meaning zero. The noughties became a common name for the decade in the United Kingdom^{[19][20][21][22][23]} and in New Zealand and Australia.^[24][25]

Although use of the word aught to refer to zero is not widespread in the United States, the use of aughts to identify the decade became common there.^[26][27][28]

Other spoken-word possibilities included "two-thousands", "twenty hundreds", "ohs", "oh ohs", "double ohs", "zeros", and "double zeros".^[29][30][31] The years of the decade can be referred to as '01, '02, etc., pronounced oh-one, oh-two, etc.^{[citation needed]}

The war on terror and War in Afghanistan began after the September 11 attacks in 2001.^[37][38] The International Criminal Court was formed in 2002. In 2003 a United States-led coalition invaded Iraq, and the Iraq War led to the end of Saddam Hussein's rule as Iraqi President and the Ba'ath Party in Iraq. Al-Qaeda and affiliated Islamist militant groups performed terrorist acts throughout the decade. These acts included the 2004 Madrid train bombings, 7/7 London bombings in 2005, and the 2008 Mumbai attacks related to al-Qaeda. The European Union expanded its sanctions amid Iran's failure to comply with its transparency obligations under the Treaty on the Non-Proliferation of Nuclear Weapons and United Nations resolutions.

The war on terror generated extreme controversy around the world, with questions regarding the justification for certain U.S. actions leading to a loss of support for the American government, both in and outside the United States.^[39] The additional armed conflict occurred in the Middle East, including between Israel and Hezbollah, then with Israel and Hamas. The most significant loss of life due to natural disasters came from the 2004 Indian Ocean earthquake, which caused a tsunami that killed around one quarter-million people and displaced well over a million others.

The most prominent terrorist attacks committed against the civilian population during the decade include:

• September 11 attacks in New York City; Washington, D.C.; and Shanksville, Pennsylvania (2,977 killed)
• 2001 anthrax attacks in the United States (5 killed, 17 infected)
• 2002 Moscow theater hostage crisis in Moscow, Russia (171 killed)
• 2002 Bali bombings in Bali, Indonesia (202 killed)
• 2003 Casablanca bombings in Casablanca, Morocco (45 killed)
• 2003 Istanbul bombings in Istanbul, Turkey (57 killed)
• 2004 Madrid train bombings (192 killed)
• 2004 Beslan school hostage crisis (334 killed)
• 2005 London bombings (56 killed)
• 2007 Yazidi communities bombings (796 killed)
• 2008 Mumbai attacks (175 killed)
• 2009 Boko Haram uprising (1000+ killed)

The most prominent armed conflicts of the decade include:

• War on terror (2001–present) – refers to several ideological, military, and diplomatic campaigns aimed at putting an end to international terrorism by preventing groups defined by the U.S. and its allies as terrorist (mostly Islamist groups such as al-Qaeda, Hezbollah, and Hamas) from posing a threat to the U.S. and its allies, and by putting an end to state sponsorship of terrorism. The campaigns were launched by the United States, with support from NATO and other allies, following the September 11 attacks that were carried out by al-Qaeda. Today the term has become mostly associated with Bush administration-led wars in Afghanistan and Iraq.
  • War in Afghanistan (2001–2021) – In 2001, the United States, the United Kingdom, Italy, Spain, Canada, and Australia invaded Afghanistan seeking to oust the Taliban and find al-Qaeda mastermind Osama bin Laden. In 2011, the US government claimed Navy Seals had killed Bin Laden and buried his body at sea. Fatalities of coalition troops: 1,553 (2001 to 2009).^[40]
  • Iraq War (2003–2011) – In 2003, the United States, the United Kingdom, Spain, Australia, and Poland invaded and occupied Iraq. Claims that Iraq had weapons of mass destruction at its disposal were later found to be unproven.^[41] The war, which ended the rule of Saddam Hussein's Ba'ath Party, also led to violence against the coalition forces and between many Sunni and Shia Iraqi groups and al-Qaeda operations in Iraq. Casualties of the Iraq War: Approximately 110,600 between March 2003 to April 2009. Hussein was eventually sentenced to death and hanged on December 30, 2006.
• Arab–Israeli conflict (1948 – present)
  • 2006 Lebanon War (summer 2006) – took place in southern Lebanon and northern Israel. The principal parties were Hezbollah paramilitary forces and the Israeli military. The war that began as a military operation in response to the abduction of two Israeli reserve soldiers by the Hezbollah gradually strengthened and became a wider confrontation.
  • Israeli–Palestinian conflict (Early 20th century – present)
    • Second Intifada (2000–2005) – After the signing of the Oslo Accords failed to bring about a Palestinian state, in September 2000, the Second Intifada (uprising) broke out, a period of intensified Palestinian-Israeli violence, which has been taking place until the present day. As a result of the significant increase of suicide bombing attacks within Israeli population centers during the first years of the Al-Aqsa Intifada,^[42] in June 2002 Israel began the construction of the West Bank Fence along the Green Line border arguing that the barrier is necessary to protect Israeli civilians from Palestinian terrorism. The significantly reduced number of incidents of suicide bombings from 2002 to 2005 has been partly attributed to the barrier.^[43] The barrier's construction, which has been highly controversial, became a significant issue of contention between the two sides. The Second Intifada has caused thousands of victims on both sides, both among combatants and among civilians – The death toll, including both military and civilian, is estimated to be 5,500 Palestinians and over 1,000 Israelis, as well as 64 foreign citizens.^[44] Many Palestinians consider the Second Intifada to be a legitimate war of national liberation against foreign occupation, whereas many Israelis consider it to be a terrorist campaign.^[45]
    • Gaza War (2008–2009) – the frequent Hamas Qassam rocket and mortar fire launched from within civilian population centers in Gaza towards the Israeli southern civilian communities led to an Israeli military operation in Gaza, which had the stated aim of reducing the Hamas rocket attacks and stopping the arms smuggling into the Gaza Strip. Throughout the conflict, Hamas further intensified its rocket and mortar attacks against Israel, hitting civilian targets and reaching major Israeli cities Beersheba and Ashdod, for the first time. The intense urban warfare in densely populated Gaza combined with the use of massive firepower by the Israeli side^[46] and the intensified Hamas rocket attacks towards populated Israeli civilian targets led to a high toll on the Palestinian side and among civilians.^[47]
• The Second Congo War (1998–2003) – took place mainly in the Democratic Republic of the Congo. The widest interstate war in modern African history, it directly involved nine African nations, as well as about twenty armed groups. It earned the epithet of "Africa's World War" and the "Great War of Africa." An estimated 3.8 million people died, mostly from starvation and disease brought about by the deadliest conflict since World War II. Millions more were displaced from their homes or sought asylum in neighboring countries.
• Russo-Georgian War (2008) – Russia invaded Georgia in response to Georgian aggression towards civilians and attack on South Ossetia. Both Russia and Georgia were condemned internationally for their actions.
• The Second Chechen War (1999–2000) – the war was launched by the Russia on August 26, 1999, in response to the war in Dagestan and the 1999 Russian apartment bombings, which were blamed on the Chechens. During the war, Russian forces largely recaptured the separatist region of Chechnya.^[48] The campaign largely reversed the outcome of the First Chechen War, in which the region gained de facto independence as the Chechen Republic of Ichkeria.
• The Eritrean–Ethiopian War came to a close in 2000.
• Kivu conflict (2004–2009) – armed conflict between the military of the Democratic Republic of the Congo (FARDC) and the Hutu Power group Democratic Forces for the Liberation of Rwanda (FDLR).
• 2009 Boko Haram uprising – an armed conflict between Boko Haram, a militant Islamist group, and Nigerian security forces.

• War in Darfur (2003–2020) – an armed conflict in the Darfur region of western Sudan. The conflict began when the Sudan Liberation Movement/Army (SLM/A) and Justice and Equality Movement (JEM) in Darfur took up arms, accusing the government of oppressing black Africans in favor of Arabs. One side was composed mainly of the Sudanese military and the Sudanese militia group Janjaweed, recruited mostly from the Afro-Arab Abbala tribes of the northern Rizeigat region in Sudan. The other side was made up of rebel groups, notably the Sudan Liberation Movement/Army and the Justice and Equality Movement, recruited primarily from the non-Arab Muslim Fur, Zaghawa, and Masalit ethnic groups. Millions of people were displaced from their homes during the conflict.^[49] There are various estimates on the number of human casualties – Sudanese authorities claim a death toll of roughly 19,500 civilians^[50] while certain non-governmental organizations, such as the Coalition for International Justice, claim that over 400,000 people have been killed during the conflict.^[51] Former U.S. President George W. Bush called the events in Darfur a genocide during his presidency.^[52][53][54] The United States Congress unanimously passed House Concurrent Resolution 467, which declared the situation in Darfur a state-sponsored genocide by the Janjaweed.^[55] In 2008, the International Criminal Court charged Omar al-Bashir with genocide for his role in the War in Darfur.^{[56][57][58][59]}
• Mexican drug war (2006–present) – an armed conflict fought between rival drug cartels and the Mexican Armed Forces. Although Mexican drug cartels, or drug trafficking organizations, have existed for quite some time, they have become more powerful since the demise of Colombia's Cali and Medellín cartels in the 1990s. Mexican drug cartels now dominate the wholesale illicit drug market in the United States.^[60] Arrests of key cartel leaders, particularly in the Tijuana and Gulf cartels, have led to increasing drug violence as cartels fight for control of the trafficking routes into the United States.^[61][62][63] Roughly more than 16,851 people in total were killed between December 2006 until November 2009.^[64]

• 

  In India, Naxalite–Maoist insurgency (1967–present) has grown alarmingly with attacks such as April 2010 Maoist attack in Dantewada, Jnaneswari Express train derailment, and Rafiganj train disaster. Naxalites are a group of far-left radical communists, supportive of Maoist political sentiment and ideology. It is presently the longest continuously active conflict worldwide. In 2006 Prime Minister Manmohan Singh called the Naxalites "The single biggest internal security challenge ever faced by our country."^[65] In 2009, he said the country was "losing the battle against Maoist rebels".^[66] According to standard definitions the Naxalite–Maoist insurgency is an ongoing conflict^[67] between Maoist groups, known as Naxalites or Naxals, and the Indian government.^[65] On April 6, 2010, Maoist rebels killed 75 security forces in a jungle ambush in central India in the worst-ever massacre of security forces by the insurgents. On the same day, Gopal, a top Maoist leader, said the attack was a "direct consequence" of the government's Operation Green Hunt offensive. This raised some voices of use of Indian Air Force against Naxalites, which were, however, declined, citing "We can't use oppressive force against our own people".^[68]
• The Colombian conflict continues causing deaths and terror in Colombia. Beginning in 1964, the FARC and ELN narcoterrorist groups were taking control of rural areas of the country by the beginning of the decade, while terrorist paramilitaries grew in other places as businesspeople and politicians thought the State would lose the war against guerrillas. However, after the failure of the peace process and the activation of Plan Colombia, Álvaro Uribe was elected president in 2002, starting a massive attack on terrorist groups, with cooperation from civil population, foreign aid and legal armed forces. The AUC paramilitary organization disbanded in 2006, while ELN guerrillas have been weakened. The Popular Liberation Army demobilized while the country's biggest terrorist group, FARC has been weakened and most of their top commanders have been killed or died during the decade. During the second half of the decade, a new criminal band has been formed by former members of AUC who did not demobilize, calling themselves "Aguilas Negras". Although the Colombian State has taken back control over most of the country, narcoterrorism still causes pain in the country. Since 2008, the Internet has become a new field of battle. Facebook has gained nationwide popularity and has become the birthplace of many civil movements against narcoterrorism such as "Colombia Soy Yo" (I am Colombia) or "Fundación Un Millón de Voces" (One Million Voices Foundation), responsible for the international protests against illegal groups during the last years.
• The Sierra Leone Civil War (1991–2002) came to an end when the Revolutionary United Front (RUF) finally laid down their arms. More than two million people were displaced from their homes because of the conflict (well over one-third of the population) many of whom became refugees in neighboring countries. Tens of thousands were killed during the conflict.^[69]
• The Sri Lankan Civil War (1983–2009) came to an end after the government defeated the Liberation Tigers of Tamil Eelam. Over 80,000 people were killed during the course of the conflict.^[70]
• Insurgency in Khyber Pakhtunkhwa (2004–present) – an armed conflict between the Pakistani Armed Forces and Islamic militants made up of local tribesmen, the Taliban, and foreign Mujahideen (Holy Warriors). It began in 2004 when tensions rooted in the Pakistani Army's search for al-Qaeda members in Pakistan's mountainous Waziristan area (in the Federally Administered Tribal Areas) escalated into armed resistance by local tribesmen. The violence has displaced 3.44 million civilians^[71] and led to more than 7,000 civilians being killed.^[72]
• The Angolan Civil War (1975–2002), once a major proxy conflict of the Cold War, the conflict ended after the anti-Communist organization UNITA disbanded to become a political party. By the time the 27-year conflict was formally brought to an end, an estimated 500,000 people had been killed.^[73]
• Shia insurgency in Yemen (2004–present) – a civil war in the Sada'a Governorate of Yemen. It began after the Shia Zaidiyyah sect launched an uprising against the Yemeni government. The Yemeni government has accused Iran of directing and financing the insurgency.^[74] Thousands of rebels and civilians have been killed during the conflict.^[75][76]
• Somali Civil War (1991–present)
  • War in Somalia (2006–2009) – involved largely Ethiopian and Somali Transitional Federal Government (TFG) forces who fought against the Somali Islamist umbrella group, the Islamic Court Union (ICU), and other affiliated militias for control of the country. The war spawned pirates who hijacked hundreds of ships off the coast of Somalia, holding ships and crew for ransom often for months (see also Piracy in Somalia). 1.9 million people were displaced from their homes during the conflict^[77] and the number of civilian casualties during the conflict is estimated at 16,724.^[78]
  • Somali civil war (2009–present) – involved largely the forces of the Somali Somali Transitional Federal Government (TFG) assisted by African Union peacekeeping troops, whom fought against various militant Islamist factions for control of the country. The violence has displaced thousands of people residing in Mogadishu, the nation's capital. 1,739 people in total were killed between January 1, 2009, and January 1, 2010.^[79]
• Conflict in the Niger Delta (2004–present) – an ongoing conflict in the Niger Delta region of Nigeria. The conflict was caused due to the tensions between the foreign oil corporations and a number of the Niger Delta's minority ethnic groups who felt they were being exploited, particularly the Ogoni and the Ijaw. The competition for oil wealth has led to an endless violence cycle between innumerable ethnic groups, causing the militarization of nearly the entire region that was occupied by militia groups as well as Nigerian military and the forces of the Nigerian Police.
• Algerian Civil War (1991–2002) – the conflict effectively ended with a government victory, following the surrender of the Islamic Salvation Army and the 2002 defeat of the Armed Islamic Group. It is estimated that more than 100,000 people were killed during the course of the conflict.
• Civil war in Chad (1998–present)
  • Chadian Civil War (1998–2002) – involved the Movement for Justice and Democracy in Chad (MDJT) rebels that skirmished periodically with government troops in the Tibesti region, resulting in hundreds of civilian, government, and rebel casualties.
  • Chadian Civil War (2005–2010) – involved Chadian government forces and several Chadian rebel groups. The Government of Chad estimated in January 2006 that 614 Chadian citizens had been killed in cross-border raids.^[80] The fighting still continues despite several attempts to reach agreements.
• Nepalese Civil War (1996–2006) – the conflict ended with a peace agreement was reached between the government and the Maoist party in which it was set that the Maoists would take part in the new government in return for surrendering their weapons to the UN. It is estimated that more than 12,700 people were killed during the course of the conflict.^[81]
• Second Liberian Civil War (1999–2003) – The conflict began in 1999 when a rebel group Liberians United for Reconciliation and Democracy (LURD), with support from the Government of Guinea, took over northern Liberia through a coup. In early 2003, a different rebel group, the Movement for Democracy in Liberia, emerged in the south. As a result, by June–July 2003, president Charles Taylor's government controlled only a third of the country. The capital Monrovia was besieged by LURD, and that group's shelling of the city resulted in the deaths of many civilians. Thousands of people were displaced from their homes as a result of the conflict.
• Insurgency in the Maghreb (2002–present) – Algeria has been the subject of an Islamic insurgency since 2002 waged by the Sunni Islamic Jihadist militant group Salafist Group for Preaching and Combat (GSPC). GSPC allied itself with the Al-Qaeda Organization in the Islamic Maghreb against the Algerian government. The conflict has since spread to other neighboring countries.
• Ituri conflict (1999–2007) – a conflict fought between the Lendu and Hema ethnic groups in the Ituri region of northeastern Democratic Republic of Congo (DRC). While there have been many phases to the conflict, the most recent armed clashes ran from 1999 to 2003, with a low-level conflict continuing until 2007. More than 50,000 people have been killed in the conflict and hundreds of thousands forced from their homes.^[82]
• Central African Republic Bush War (2004–2007) – began with the rebellion by the Union of Democratic Forces for Unity (UFDR) rebels, after the current president of the Central African Republic, François Bozizé, seized power in a 2003 coup. The violence has displaced around 10,000 civilians and has led to hundreds of civilians being killed.
• Afghan Civil War (1996–2001) – an armed conflict that continued after the capture of Kabul by the Taliban, in which the formation of the Afghan Northern Alliance attempted to oust the Taliban. It proved largely unsuccessful, as the Taliban continued to make gains and eliminated much of the Alliance's leadership.

The most prominent coup d'état of the decade include:

• 2000 overthrow of Slobodan Milošević in the Federal Republic of Yugoslavia – after Slobodan Milošević was accused by opposition figures of winning the 2000 election through electoral fraud, mass protests led by the opposition movement Otpor! pressure Slobodan Milošević to resign. Milošević was later arrested in 2001 and sent to the Hague to face war crimes charges for his alleged involvement in war crimes of the Yugoslav Wars.
• 2002 Venezuelan coup attempt – a failed military coup d'état on April 11, 2002, which aimed to overthrow the president of Venezuela Hugo Chávez. During the coup Hugo Chávez was arrested and Pedro Carmona became the interim President for 47 hours. The coup led to a pro-Chávez uprising that the Metropolitan Police attempted to suppress. The pro-Chávez Presidential Guard eventually retook the Miraflores presidential palace without firing a shot, leading to the collapse of the Carmona government.
• 2004 Haitian coup d'état – a conflict fought for several weeks in Haiti during February 2004 that resulted in the premature end of President Jean-Bertrand Aristide's second term, and the installment of an interim government led by Gérard Latortue.
• 2006 Thai coup d'état – on September 19, 2006, while the elected Thai Prime Minister Thaksin Shinawatra was in New York for a meeting of the UN, Army Commander-in-Chief Lieutenant General Sonthi Boonyaratglin launched a bloodless coup d'état.
• Fatah–Hamas conflict (2006–present) – an armed conflict fought between the two main Palestinian factions, Fatah and Hamas with each vying to assume political control of the Palestinian territories. In June 2007, Hamas took control of the entire Gaza Strip, and established a separate government while Fatah remained in control of the West Bank. This in practice divided the Palestinian Authority into two. Various forces affiliated with Fatah engaged in combat with Hamas, in numerous gun battles. Most Fatah leaders eventually escaped to Egypt and the West Bank, while some were captured and killed.
• 2009 Honduran coup d'état – The armed forces of the country entered the president's residence and overthrew president Manuel Zelaya. (see 2009 Honduran constitutional crisis).

• Since 2005, Iran's nuclear program has become the subject of contention with the Western world due to suspicions that Iran could divert the civilian nuclear technology to a weapons program. This has led the UN Security Council to impose sanctions against Iran on select companies linked to this program, thus furthering its economic isolation on the international scene. The U.S. Director of National Intelligence said in February 2009 that Iran would not realistically be able to a get a nuclear weapon until 2013, if it chose to develop one.^[83]
• In 2003, the United States invaded Iraq over allegations that its leader Saddam Hussein was stockpiling weapons of mass destruction including chemical and biological weapons or was in the process of creating them. None were found, spawning multiple theories.
• North Korea successfully performed two nuclear tests in 2006 and 2009.
• Operation Orchard – during the operation, Israel bombed what was believed to be a Syrian nuclear reactor on September 6, 2007, which was thought to be built with the aid of North Korea.^[84] The White House and Central Intelligence Agency (CIA) later declared that American intelligence indicated the site was a nuclear facility with a military purpose, though Syria denies this.^[85]
• The Doomsday Clock, the symbolic representation of the threat of nuclear annihilation, moved four minutes closer to midnight: two minutes in 2002 and two minutes in 2007 to 5 minutes to midnight.

• East Timor regains independence from Indonesia in 2002. Portugal granted independence to East Timor in 1975, but it was soon after invaded by Indonesia, which only recognized East Timorese independence in 2002.
• Montenegro gains independence from Serbia in 2006, ending the 88-year-old Yugoslavia.
• Kosovo declares independence from Serbia in 2008, though its independence still remains unrecognized by many countries.
• On August 23, 2005, Israel's unilateral disengagement from 25 Jewish settlements in the Gaza Strip and West Bank ends.
• On August 26, 2008, Russia formally recognises the disputed Georgian regions of Abkhazia and South Ossetia as independent states.^[86] The vast majority of United Nations member states maintain that the areas belong to Georgia.

During the 2000s, the expectations and unspoken rules for acceptable conduct among American politicians affiliated with the Republican or Democratic Parties changed due to the decline of political bosses in the previous 4 decades and the momentous events in America that happened during the decade.^[87]

Generally, American presidential candidates abided by and respected the established procedures of both major parties' presidential nomination process.^[87]

During this decade, the peaceful transfer of power through elections first occurred in Mexico, Indonesia, Taiwan, Colombia, and several other countries. (See below.)

The prominent political events of the decade include:

• Paul Martin replaces Jean Chrétien as Prime Minister of Canada in 2003 July 23 by becoming the new leader of the Liberal Party. Stephen Harper was elected prime minister in 2006 following the defeat of Paul Martin's government in a motion of no confidence.

• Greenland was granted further Self-governance (or "self-rule") within the Kingdom of Denmark on June 21, 2009.^[88]

• Vicente Fox was elected President of Mexico in the 2000 presidential election, making him the first president elected from an opposition party in 71 years, defeating the then-dominant Institutional Revolutionary Party (PRI).^[89]

• George W. Bush was sworn in succeeding Bill Clinton as the 43rd President of the United States on January 20, 2001, following a sharply contested election.
• On October 26, 2001, U.S. President George W. Bush signed the USA PATRIOT Act into law.
• On February 15, 2003, anti-war protests broke out around the world in opposition to the U.S. Invasion of Iraq, in what the Guinness Book of World Records called the largest anti-war rally in human history.^[90] In reaction, The New York Times writer Patrick Tyler wrote in a February 17 article that: ...the huge anti-war demonstrations around the world this weekend are reminders that there may still be two superpowers on the planet: the United States and world public opinion.^[91]

MRSA is thought to have caused 1,652 deaths in 2006 in UK up from 51 in 1993.

The 2009 H1N1 (swine flu) flu pandemic was also considered a natural disaster.

The most significant evolution of the 2000s in the economic landscape was the long-time predicted breakthrough of economic giant China, whose GDP grew from 1.21 trillion to 5.1 trillion (in 2022 USD).^[124] To a lesser extent, India also benefited from an economic boom (growing from 438.39 billion to 1.34 trillion)^[125] which saw the two most populous countries becoming an increasingly dominant economic force.^[126] The rapid catching-up of emerging economies with developed countries sparked some protectionist tensions during the period and was partly responsible for an increase in energy and food prices at the end of the decade. The economic developments in the latter third of the decade were dominated by a worldwide economic downturn, which started with the crisis in housing and credit in the United States in late 2007, and led to the bankruptcy of major banks and other financial institutions.^[127] The outbreak of this global financial crisis sparked a global recession, beginning in the United States and affecting most of the industrialized world.

• A study by the World Institute for Development Economics Research at United Nations University reports that the richest 1% of adults alone owned 40% of global assets in the year 2000. The three richest people possess more financial assets than the lowest 48 nations combined.^{[citation needed]}

The combined wealth of the "10 million dollar millionaires" grew to nearly $41 trillion in 2008.^[128]

• The sale of UK gold reserves, 1999–2002 was a policy pursued by HM Treasury when gold prices were at their lowest in 20 years, following an extended bear market. The period itself has been dubbed by some commentators as the Brown Bottom or Brown's Bottom.^{[129][130][131][132][133][134]}

The period takes its name from Gordon Brown, the then UK Chancellor of the Exchequer (who later became Prime Minister), who decided to sell approximately half of the UK's gold reserves in a series of auctions. At the time, the UK's gold reserves were worth about US$6.5 billion, accounting for about half of the UK's US$13 billion foreign currency net reserves.^[135]

• On October 9, 2007, the Dow Jones Industrial Average closed at the record level of 14,164.53. Two days later on October 11, the Dow would trade at its highest intra-day level ever, at the 14,198.10 mark.^[139] In what would normally take many years to accomplish; numerous reasons were cited for the Dow's extremely rapid rise from the 11,000 level in early 2006, to the 14,000 level in late 2007. They included future possible takeovers and mergers, healthy earnings reports particularly in the tech sector, and moderate inflationary numbers; fueling speculation the Federal Reserve would not raise interest rates. Roughly on par with the 2000 record when adjusted for inflation, this represented the final high of the cyclical bull. The index closed 2007 at 13,264.82, a level it would not surpass for nearly five years.

Between 1999 and 2009, according to the World Bank statistics for GDP:^[140][141]

• The world economy by nominal GDP almost doubled in size from U.S. $30.21 trillion in 1999 to U.S. $58.23 trillion in 2009. This figure is not adjusted for inflation. By PPP, world GDP rose 78%, according to the IMF. But inflation adjusted nominal GDP rose only 42%, according to IMF constant price growth rates.^[142] The following figures are not inflation adjusted nominal GDP and should be interpreted with extreme caution:
• The United States (U.S. $14.26 trillion) retained its position of possessing the world's largest economy. However, the size of its contribution to the total global economy dropped from 28.8% to 24.5% by nominal price or a fall from 23.8% to 20.4% adjusted for purchasing power.
• Japan (U.S. $5.07 trillion) retained its position of possessing the second largest economy in the world, but its contribution to the world economy also shrank significantly from 14.5% to 8.7% by nominal price or a fall from 7.8% to 6.0% adjusted for purchasing power.
• China (U.S. $4.98 trillion) went from being the sixth largest to the third largest economy, and in 2009 contributed to 8.6% of the world's economy, up from 3.3% in 1999 by nominal price or a rise from 6.9% to 12.6% adjusted for purchasing power.
• Germany (U.S. $3.35 trillion), France (U.S. $2.65 trillion), United Kingdom (U.S. $2.17 trillion) and Italy (U.S. $2.11 trillion) followed as the 4th, 5th, 6th and 7th largest economies, respectively in 2009.
• Brazil (U.S. $1.57 trillion) retained its position as the 8th largest economy, followed by Spain (U.S. $1.46 trillion), which remained at 10th.
• Other major economies included Canada (U.S. $1.34 trillion; 10th, down from 9th), India (U.S. $1.31 trillion; remaining at 11th from 12th), Russia (U.S. $1.23 trillion; from 16th to 12th) Mexico (U.S. $875 billion; 14th, down from 11th), Australia (U.S. $925 billion; from 14th to 13th) and South Korea (U.S. $832 billion; 15th, down from 13th).
• In terms of purchasing power parity in 2009, the ten largest economies were the United States (U.S. $14.26 trillion), China (U.S. $9.10 trillion), Japan (U.S. $4.14 trillion), India (U.S. $3.75 trillion), Germany (U.S. $2.98 trillion), Russia (U.S. $2.69 trillion), United Kingdom (U.S. $2.26 trillion), France (U.S. $2.17 trillion), Brazil (U.S. $2.02 trillion), and Italy (U.S. $1.92 trillion).^[143][144]
• The average house price in the UK, increased by 132% between the fourth quarter of 2000, and 91% during the decade; but the average salary increased only by 40%.^[145]

The removal of trade and investment barriers, the growth of domestic markets, artificially low currencies, the proliferation of education, the rapid development of high tech and information systems industries and the growth of the world economy lead to a significant growth of offshore outsourcing during the decade as many multinational corporations significantly increased subcontracting of manufacturing (and increasingly, services) across national boundaries in developing countries and particularly in China and India, due to many benefits and mainly because the two countries which are the two most populous countries in the world provide huge pools from which to find talent and as because both countries are low cost sourcing countries. As a result of this growth, many of these developing countries accumulated capital and started investing abroad. Other countries, including the United Arab Emirates, Australia, Brazil and Russia, benefited from increased demand for their mineral and energy resources that global growth generated. The hollowing out of manufacturing was felt in Japan and parts of the United States and Europe which had not been able to develop successful innovative industries. Opponents point out that the practice of offshore outsourcing by countries with higher wages leads to the reduction of their own domestic employment and domestic investment. As a result, many customer service jobs as well as jobs in the information technology sectors (data processing, computer programming, and technical support) in countries such as the United States and the United Kingdom have been or are potentially affected.

While global trade rose in the decade (partially driven by China's entry into the WTO in 2001), there was little progress in the multilateral trading system. International trade continued to expand during the decade as emerging economies and developing countries, in particular China and South-Asian countries, benefited low wages costs and most often undervalued currencies. However, global negotiations to reduce tariffs did not make much progress, as member countries of the World Trade Organization did not succeed in finding agreements to stretch the extent of free trade.^[146] The Doha Round of negotiations, launched in 2001 by the WTO to promote development, failed to be completed because of growing tensions between regional areas. Nor did the Cancún Conference in 2003 find a consensus on services trade^[147] and agricultural subsidies.^[148]

The comparative rise of China, India, and other developing countries also contributed to their growing clout in international forums. In 2009, it was determined that the G20, originally a forum of finance ministers and central bank governors, would replace the G8 as the main economic council.

2007 Chinese export recalls – in 2007, a series of product recalls and import bans were imposed by the product safety institutions of the United States, Canada, the European Union, Australia and New Zealand against products manufactured in and exported from the mainland of the People's Republic of China (PRC) because of numerous alleged consumer safety issues.

Events in the confidence crisis included recalls on consumer goods such as pet food, toys, toothpaste, lipstick, and a ban on certain types of seafood. Also included are reports on the poor crash safety of Chinese automobiles, slated to enter the American and European markets in 2008. This created adverse consequences for the confidence in the safety and quality of mainland Chinese manufactured goods in the global economy.

The decade was marked by two financial and economic crises. In 2001, the Dot-com bubble burst, causing turmoil in financial markets and a decline in economic activity in the developed economies, in particular in the United States.^[149] However, the impact of the crisis on the activity was limited thanks to the intervention of the central banks, notably the U.S. Federal Reserve System. Indeed, Alan Greenspan, leader of the Federal Reserve until 2006, cut the interest rates several times to avoid a severe recession,^[150] allowing an economic revival in the U.S.^[151]

As the Federal Reserve maintained low interest rates to favor economic growth, a housing bubble began to appear in the United States. In 2007, the rise in interest rates and the collapse of the housing market caused a wave of loan payment failures in the U.S. The subsequent mortgage crisis caused a global financial crisis, because the subprime mortgages had been securitized and sold to international banks and investment funds. Despite the extensive intervention of central banks, including partial and total nationalization of major European banks,^[152][153] the crisis of sovereign debt became particularly acute, first in Iceland, though as events of the early 2010s would show, it was not an isolated European example. Economic activity was severely affected around the world in 2008 and 2009,^[154] with disastrous consequences for carmakers.^[155]

In 2007, the UK's Chancellor of the Exchequer Gordon Brown, delivered his final Mansion House speech as Chancellor before he moved into Number 10. Addressing financiers: "A new world order has been created", Everyone needed to follow the city's "great example", "an era that history will record as the beginning of a new Golden Age".^[156]

Reactions of governments in all developed and developing countries against the economic slowdown were largely inspired by keynesian economics. The end of the decade was characterized by a Keynesian resurgence,^[157] while the influence and media popularity of left-wing economists^[158] Joseph Stiglitz and Paul Krugman (Nobel Prize recipients in 2001 and 2008, respectively) did not stop growing during the decade.^[159] Several international summits were organized to find solutions against the economic crisis and to impose greater control on the financial markets. The G20 became in 2008 and 2009 a major organization, as leaders of the member countries held two major summits in Washington in November 2008 and in London in April 2009 to regulate the banking and financial sectors,^[160] and also succeeding in coordinating their economic action and in avoiding protectionist reactions.

From the mid-1980s to September 2003, the inflation-adjusted price of a barrel of crude oil on NYMEX was generally under $25/barrel. During 2003, the price rose above $30, reached $60 by August 11, 2005, and peaked at $147.30 in July 2008.^[161] Commentators attributed these price increases to many factors, including reports from the United States Department of Energy and others showing a decline in petroleum reserves, worries over peak oil, Middle East tension, and oil price speculation.^[162]

For a time, geopolitical events and natural disasters indirectly related to the global oil market had strong short-term effects on oil prices. These events and disasters included North Korean missile tests, the 2006 conflict between Israel and Lebanon, worries over Iranian nuclear plants in 2006 and Hurricane Katrina. By 2008, such pressures appeared to have an insignificant impact on oil prices given the onset of the global recession. The recession caused demand for energy to shrink in late 2008 and early 2009 and the price plunged as well. However, it surged back in May 2009, bringing it back to November 2008 levels.^[163]

Many fast-growing economies throughout the world, especially in Asia, also were a major factor in the rapidly increasing demand for fossil fuels, which—along with fewer new petroleum finds, greater extraction costs, and political turmoil—forced two other trends: a soar in the price of petroleum products and a push by governments and businesses to promote the development of environmentally friendly technology (known informally as "green" technology). However, a side-effect of the push by some industrial nations to "go green" and utilize biofuels was a decrease in the supply of food and a subsequent increase in the price of the same. It partially caused the 2007 food price crisis, which seriously affected the world's poorer nations with an even more severe shortage of food.^[164]

A common currency for most EU member states, the euro, was established electronically in 1999, officially tying all the currencies of each participating nation to each other. The new currency was put into circulation in 2002 and the old currencies were phased out. Only three countries of the then 15 member states decided not to join the euro (the United Kingdom, Denmark and Sweden). In 2004 the EU undertook a major eastward enlargement, admitting 10 new member states (eight of which were former communist states). Two more, Bulgaria and Romania, joined in 2007, establishing a union of 27 nations.

The euro has since become the second largest reserve currency and the second most traded currency in the world after the US$.^[165] As of October 2009^[update], with more than €790 billion in circulation, the euro was the currency with the highest combined value of banknotes and coins in circulation in the world, having surpassed the US$.^{[note 1]}

• 2006 – Grigori Perelman is a Russian mathematician who has made landmark contributions to Riemannian geometry and geometric topology. In 2003, he proved Thurston's geometrization conjecture. This consequently solved in the affirmative the Poincaré conjecture, posed in 1904, which before its solution was viewed as one of the most important and difficult open problems in topology. In August 2006, Perelman was awarded the Fields Medal^[169] for "his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow." Perelman declined to accept the award or to appear at the congress, stating: "I'm not interested in money or fame, I don't want to be on display like an animal in a zoo."^[170] On December 22, 2006, the journal Science recognized Perelman's proof of the Poincaré conjecture as the scientific "Breakthrough of the Year", the first such recognition in the area of mathematics.^[171] The Poincaré conjecture is one of the seven Millennium Problems and the first to be solved.

• The popularity of mobile phones and text messaging surged in the 2000s in the Western world. The advent of text messaging made possible new forms of interaction that were not possible before, leading to positive implications such as having the ability to receive information on the move. Nevertheless, it also led to negative social implications such as "cyberbullying" and the rise of traffic collisions caused by drivers who were distracted as they were texting while driving.
• Mobile internet, first launched in Japan with the i-mode in 1999, became increasingly popular with people in developed countries throughout the decade, thanks to improving cell phone capabilities and advances in mobile telecommunications technology, such as 3G.
• E-mail continued to be popular throughout the decade. It began to replace "snail mail" (also known, more neutrally, as paper mail, postal mail, land mail, or simply mail or post) as the primary way of sending letters and other messages to people in faraway locations, though it has been available since 1971.
• Social networking sites arose as a new way for people to stay in touch no matter where they are, as long as they have an internet connection. The earliest social networking sites were Friendster, Myspace, Facebook, and Twitter in 2002, 2003, 2004, and 2006, respectively. Myspace was the most popular social networking website until June 2009 when Facebook overtook Myspace in the number of American users.^[180]
• Smartphones, which combine mobile phones with the features of personal digital assistants and portable media players, first emerged in the 1990s but did not become popular until the late 2000s. Smartphones are rich in features and often have high resolution touchscreens and web browsers. The first modern smartphone was the iPhone 2G. It was released in June 2007 in the United States, and in November 2007, the United Kingdom, France, Germany, Portugal, Ireland and Austria. It was the first smartphone to not include a physical keyboard, solely utilizing a touch screen and a home button.
• Due to the major success of broadband Internet connections, VoIP starts to gain popularity as a replacement for traditional telephone lines.

In the 2000s, the Internet became a mainstay, strengthening its grip on Western society while becoming increasingly available in the developing world. The share of the world population using the internet grew from 6.7% to 25.7%.^[181]

• A huge jump in broadband internet usage globally – for example, from 6% of U.S. internet users in June 2000^[182] to what one mid-decade study predicted would be 62% by 2010.^[183] By February 2007, over 80% of U.S. Internet users were connected via broadband and broadband internet has been almost a required standard for quality internet browsing.^[184]
• Wireless internet became prominent by the end of the decade, as well as internet access in devices besides computers, such as mobile phones and gaming consoles.
• Email became a standard form of interpersonal written communication, with popular addresses available to the public on Hotmail (now Outlook.com), Gmail and Yahoo! Mail.
• Normalisation became increasingly important as massive standardized corpora and lexicons of spoken and written language became widely available to laypeople, just as documents from the paperless office were archived and retrieved with increasing efficiency using XML-based markup.
• Peer-to-peer technology gained massive popularity with file sharing systems enabling users to share any audio, video and data files or anything in digital format, as well as with applications which share real-time data, such as telephony traffic.
• VPNs (virtual private networks) became likewise accessible to the general public, and data encryption remained a major issue for the stability of web commerce.
• Boom in music downloading and the use of data compression to quickly transfer music over the Internet, with a corresponding rise of portable digital audio players. As a result, the entertainment industry struggled through the decade to find digital delivery systems for music, movies, and other media that reduce copyright infringement and preserve profit.
• The USB flash drive replaces the floppy disk as the preferred form of low-capacity mobile data storage.
• In February 2003, Dell announced floppy drives would no longer be pre-installed on Dell Dimension home computers, although they were still available as a selectable option and purchasable as an aftermarket OEM add-on.^[185] On January 29, 2007, PC World stated that only 2% of the computers they sold contained built-in floppy disk drives; once present stocks were exhausted, no more standard floppies would be sold.^[186]
• During the decade, Windows 2000, XP, Microsoft Office 2003, Vista^{[dubious – discuss]} and Office 2007 (and later Windows 7^{[dubious – discuss]}) become the ubiquitous industry standards^{[dubious – discuss]} in personal computer software until the end of the decade, when Apple began to slowly gain market share. Windows ME and Microsoft Office XP were also released during the decade.
• With the advent of the Web 2.0, dynamic technology became widely accessible, and by the mid-2000s, PHP and MySQL became (with Apache and nginx) the backbone of many sites, making programming knowledge unnecessary to publish to the web. Blogs, portals, and wikis become common electronic dissemination methods for professionals, amateurs, and businesses to conduct knowledge management typified by success of the online encyclopedia Wikipedia which launched on January 15, 2001, grew rapidly and became the largest and most popular general reference work on the Internet^[187][188] as well as the best known wiki in the world and the largest encyclopedia in the world.
• Open-source software, such as the Linux operating system, the Mozilla Firefox web browser and VLC media player, gain ground.
• Internet commerce became standard for reservations; stock trading; promotion of music, arts, literature, and film; shopping; and other activities.

• In 2007, the fast food chain McDonald's announced the introduction of free high speed wireless internet access at most of its 1,200 restaurants by the end of the year in a move which will make it the UK's biggest provider of such a service.^[189]

Google, YouTube, Ask.com and Wikipedia emerged as popular websites, becoming the 2nd, 3rd, 7th and 9th most popular websites by the end of the decade respectively. Amazon overtook eBay as the most-visited e-commerce site in 2008. AOL significantly declined in popularity throughout the decade, falling from being the most popular website to no longer being within the top 10. Excite and Lycos fell outside the top 10, and MSN fell from the second to sixth most popular site, though it quadrupled its monthly visits (going from 325 to 1.2 billion monthly visits). Yahoo! maintained relatively stable popularity, remaining the most popular website for most of the decade.^[190]

• GPS (Global Positioning System) became very popular especially in the tracking of items or people, and the use in cars (see Automotive navigation systems). Games that utilized the system, such as geocaching, emerged and became popular.
• Green laser pointers^[192] appeared on the market circa 2000, and are the most common type of DPSS lasers (also called DPSSFD for "diode pumped solid state frequency-doubled").

In late 2004 and early 2005, came a significant increase in reported incidents linked to laser pointers – see Lasers and aviation safety. The wave of incidents may have been triggered in part by "copycats" who read press accounts of laser pointer incidents. In one case, David Banach of New Jersey was charged under federal Patriot Act anti-terrorism laws, after he allegedly shone a laser pointer at aircraft.^[193]

• Chip and PIN is the brand name adopted by the banking industries in the United Kingdom and Ireland for the rollout of the EMV smart card payment system for credit, debit and ATM cards.

• In 2009, Tesco (a British multinational grocery and general merchandise retailer) opened its first UK branch at which service robots were the only option at the checkout, in Kingsley, Northampton – its US chain, Fresh & Easy, already operates several branches like this.^[194]
• September 7, 2009, an EU watchdog warns of an "alarming increase" in cash machine fraud by organised criminal gangs across Europe using sophisticated skimming technology, together with an explosion in ram-raiding attacks on ATMs.

ATM crime in Europe jumped to €485m (£423m) in 2008 following a 149% rise in attacks on cash machines. Gangs are turning to Bluetooth wireless technology to transmit card and personal identification number (PIN) details to nearby laptops and using increasingly sophisticated techniques to skim cards.

Portable laptops became popular during the late 2000s.

More conventional smash-and-grab attacks are also on the rise, says Enisa, the European Network and Information Security Agency. It reports a 32% rise in physical robberies on ATMs, ranging from ram raids to the use of rotary saws, blowtorches and diamond drills. It blames the increase on criminal gangs from eastern Europe.^[195]

American Civil Liberties Union
• France created in 2006 the first French parliamentary commission on cult activities which led to a report registering a number of cults considered as dangerous. Supporters of such movements have criticized the report on the grounds of the respect of religious freedom. Proponents of the measure contend that only dangerous cults have been listed as such, and state secularism ensures religious freedom in France.
• November 2009 – Minaret controversy in Switzerland: A referendum, a constitutional amendment banning the construction of new Mosque minarets was approved, sparking reactions from governments and political parties throughout of the world.
• 2009 – In Pope Benedict XVI's third encyclical Caritas in Veritate, he warns that a purely technocrat mindset where decisions are made only on grounds of efficiency will not deliver true development. Technical decisions must not be divorced from ethics. Benedict discusses bioethics and states that practices such as abortion, eugenics and euthanasia are morally hazardous and that accepting them can lead to greater tolerance for various forms of moral degradation. He turns to another consequence of the technocratic mindset, the viewing of people's personalities in purely psychological terms at the exclusion of the spiritual, which he says can lead to people feeling empty and abandoned even in prosperous societies.

• The decade saw further expansion of LGBTQ+ rights, with many European, Oceanic, and American countries recognizing civil unions and partnerships and a number of countries extending civil marriage to same-sex couples. The Netherlands was the first country in the world to legalize same-sex marriage in 2001. By the end of 2009, same-sex marriage was legal and performed in 10 countries worldwide, although only in some jurisdictions in Mexico and the United States.
• Population continued to grow in most countries, in particular in developing countries, though overall the rate slowed. According to United Nations estimates, world population reached six billion in late 1999,^[220] and continued to climb to 6.8 billion in late 2009.^[221] In 2007 the population of the United States reached 300 million inhabitants, and Japan's population peaked at 127 million before going into decline.^[222]
• In a 2003 memo to a staff member, Britain's Charles, Prince of Wales wrote:

  What is wrong with everyone nowadays? Why do they all seem to think they are qualified to do things far beyond their technical capabilities? This is to do with the learning culture in schools as a consequence of a child-centred system that admits no failure. People think they can all be pop stars, high court judges, brilliant TV personalities or infinitely more competent heads of state without ever putting in the necessary work or having natural ability. This is the result of social utopianism which believes humanity can be genetically and socially engineered to contradict the lessons of history ...^[223]

• Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century.^[224]

• The programme was introduced by the UK Department of Health in the winter of 2002–2003, and received some adverse media attention because of the high and rising costs of fresh fruit and vegetables. After ten years, research suggested that few people were meeting the target.^[229]
• The London congestion charge is a fee charged on most motor vehicles operating within the Congestion Charge Zone (CCZ) in central London between 07:00 and 18:00 Monday to Friday. It is not charged at weekends, public holidays or between Christmas Day and New Year's Day (inclusive). The charge, which was introduced on February 17, 2003, remains one of the largest congestion charge zones in the world.
• On December 3, 2003, New Zealand passed legislation to progressively implement a smoking ban in schools, school grounds, and workplaces by December 2004.^[230] On March 29, 2004, Ireland implemented a nationwide ban on smoking in all workplaces. In Norway, similar legislation was put into force on June 1 the same year.

Oliver's efforts to bring radical change to the school meals system, chronicled in the series Jamie's School Dinners, challenged the junk-food culture by showing schools they could serve healthy, cost-efficient meals that kids enjoyed eating.^[236] Jamie's efforts brought the subject of school dinners to the political forefront and changed the types of food served in schools.^[237]
• In 2006, nearly 11 million Plastic surgery procedures were performed in the United States alone. The number of cosmetic procedures performed in the United States has increased over 50 percent since the start of the century.^[238]
• In November 2006, the Office of Communications (Ofcom) announced that it would ban television advertisements for junk food before, during and after television programming aimed at under-16s in the United Kingdom.^[239] These regulations were originally outlined in a proposal earlier in the year. This move has been criticized on both ends of the scale; while the Food and Drink Federation labelled the ban "over the top", others have said the restrictions do not go far enough (particularly due to the fact that soap operas would be exempt from the ban).^[240] On April 1, 2007, junk food advertisements were banned from programmes aimed at four to nine-year-olds.^[241] Such advertisements broadcast during programmes "aimed at, or which would appeal to," ten to fifteen-year-olds will continue to be phased out over the coming months,^[242] with a full ban coming into effect on January 1, 2009.^[241]

Climate change and global warming became household words in the 2000s. Predictions tools made significant progress during the decade, UN-sponsored organisations such as the IPCC gained influence, and studies such as the Stern report influenced public support for paying the political and economic costs of countering climate change.

The global temperature kept climbing during the decade. In December 2009, the World Meteorological Organization (WMO) announced that the 2000s might have been the warmest decade since records began in 1850, with four of the five warmest years since 1850 having occurred in this decade.^[249][250] The NASA and the NOAA later echoed the WMO's findings.^[251]

Major natural disasters became more frequent and helped change public opinion. One of the deadliest heat waves in human history happened during the 2000s, mostly in Europe, with the 2003 European heat wave killing 37,451 people over the summer months.^[252] In February 2009, a series of highly destructive bushfires started in Victoria, Australia, lasting into the next month. While the fires are believed to have been caused by arson, they were widely reported as having been fueled by an excessive heatwave that was due in part to climate change. It has also been alleged that climate change was a cause of increased storms intensity, notably in the case of Hurricane Katrina.

Climate change became a major issue for governments, populations and scientists. Debates on global warming and its causes made significant progress, as climate change denials were refuted by most scientific studies. Decisive reports such as the Stern Review and the 2007 IPCC Report almost established a climate change consensus.^[253] NGOs' actions and the commitment of political personalities (such as former U.S. Vice President Al Gore) also urged to international reactions against climate change. Documentary films An Inconvenient Truth and Home may have had a decisive impact.^[254]

Under the auspices of The UN Convention on Climate Change the Kyoto Protocol (aimed at combating global warming) entered into force on February 16, 2005. As of November 2009, 187 states have signed and ratified the protocol.^[255] In addition The UN Convention on Climate Change helped coordinate the efforts of the international community to fight potentially disastrous effects of human activity on the planet and launched negotiations to set an ambitious program of carbon emission reduction that began in 2007 with the Bali Road Map. However, the representatives of the then 192 member countries of the United Nations gathered in December 2009 for the Copenhagen Conference failed to reach a binding agreement to reduce carbon emissions because of divisions between regional areas.

However, as environmental technologies were to make up a potential market, some countries made large investments in renewable energies, energy conservation and sustainable transport. Many governments launched national plans to promote sustainable energy. In 2003, the European Union members created an emission trading scheme, and in 2007 they assembled a climate and energy package to reduce further their carbon emission and improve their energy-efficiency. In 2009, the United States Obama administration set up the Green New Deal, a plan to create millions of jobs in sectors related to environmentalism.

The Household Waste Recycling Act 2003 requires local authorities in England to provide every household with a separate collection of at least two types of recyclable materials by 2010.^[256]

• The Millennium Bridge, London officially known as the London Millennium Footbridge, is a steel suspension bridge for pedestrians crossing the River Thames in London, England, linking Bankside with the city. Londoners nicknamed the bridge the "Wobbly Bridge" after participants in a charity walk on behalf of Save the Children to open the bridge felt an unexpected, and, for some, uncomfortable, swaying motion on the first two days after the bridge opened. The bridge was closed later that day, and after two days of limited access the bridge was closed for almost two years while modifications were made to eliminate the wobble entirely. It was reopened in 2002.

• The Hockney–Falco thesis is a controversial theory of art history, advanced by artist David Hockney and physicist Charles M. Falco, suggesting that advances in realism and accuracy in the history of Western art since the Renaissance were primarily the result of optical aids such as the camera obscura, camera lucida, and curved mirrors, rather than solely due to the development of artistic technique and skill. In a 2001 book, Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters, Hockney analyzed the work of the Old Masters and argued that the level of accuracy represented in their work is impossible to create by "eyeballing it". Since then, Hockney and Falco have produced a number of publications on positive evidence of the use of optical aids, and the historical plausibility of such methods.
• Rolf Harris is an Australian entertainer. He is a musician, a singer-songwriter, a composer, a painter, and a television personality.

• In April–June 2003, the English visual artists often known as The Chapman Brothers, held a solo show at Modern Art Oxford entitled The Rape of Creativity in which "the enfants terribles of Britart, bought a mint collection of Goya's most celebrated prints – and set about systematically defacing them".^[260] The Francisco Goya prints referred to his Disasters of War set of 80 etchings.^[260] The duo named their newly defaced works Insult to Injury.^[260] BBC described more of the exhibition's art: "Drawings of mutant Ronald McDonalds, a bronze sculpture of a painting showing a sad-faced Hitler in clown make-up and a major installation featuring a knackered old caravan and fake dog turds."^[261] The Daily Telegraph commented that the Chapman brothers had "managed to raise the hackles of art historians by violating something much more sacred to the art world than the human body – another work of art"^[262]
  • As a protest against this piece, Aaron Barschak (who later gate-crashed Prince William's 21st birthday party dressed as Osama bin Laden in a frock) threw a pot of red paint over Jake Chapman during a talk he was giving in May 2003.
• On May 5, 2004, a 1905 painting titled Garçon à la Pipe (English: Boy with a Pipe) by Pablo Picasso was sold for US$104,168,000 at Sotheby's auction in New York City. At the time, it broke the record for the amount paid for an auctioned painting (when inflation is ignored). The amount, US$104 million, includes the auction price of US$93 million plus the auction house's commission of about US$11 million. Many art critics have stated that the painting's high sale price has much more to do with the artist's name than with the merit or historical importance of the painting. The Washington Post's article^[263][264] on the sale contained the following characterisation of the reaction:

  Picasso expert Pepe Karmel, reached in New York the morning after the sale, was waxing wroth about the whole affair. "I'm stunned," he said, "that a pleasant, minor painting could command a price appropriate to a real masterwork by Picasso. This just shows how much the marketplace is divorced from the true values of art."

• On May 24, 2004, more than 100 artworks from the famous collection of art collector and sponsor of the Young British Artists (YBAs) Charles Saatchi's were destroyed in a warehouse fire on an industrial estate in Leyton, east London. Modern art classics such as Tracey Emin's tent and works by Damien Hirst, Sarah Lucas and Gary Hume were lost.

Live-action films

The usage of computer-generated imagery became more widespread in films during the 2000s. Documentary and mockumentary films, such as March of the Penguins, Borat, and Super Size Me, were popular in the 2000s. 2004's Fahrenheit 9/11 by Michael Moore is the highest-grossing documentary of all time. Online films became popular, and conversion to digital cinema started. Critically acclaimed movies released in the decade including highlights such as Eternal Sunshine of the Spotless Mind and Lost in Translation.

December 2009's Avatar, an American science fiction film written and directed by James Cameron, made extensive use of cutting edge motion capture filming techniques, and was released for traditional viewing, 3D viewing (using the RealD 3D, Dolby 3D, XpanD 3D, and IMAX 3D formats). It was also released in "4D" in select South Korean theaters.^[273]

3D films became more and more successful throughout the 2000s, culminating in the unprecedented success of 3D presentations of Avatar.

• Roger Ebert, described by Forbes as "the most powerful pundit in America",^[274] was skeptical of the resurgence of 3D effects in film, which he found unrealistic and distracting.^[275]
• In August 2004, American horror author Stephen King, in a column, criticized what he saw as a growing trend of leniency towards films from critics. His main criticism was that films, citing Spider-Man 2 as an example, were constantly given four star ratings that they did not deserve: "Formerly reliable critics who seem to have gone remarkably soft – not to say softhearted and sometimes softheaded – in their old age."^[276]

In July 2005, it was reported that the Scottish actor and producer Sir Sean Connery had decided to retire, due to disillusionment with the "idiots now in Hollywood"' Telling The New Zealand Herald: "I'm fed up with the idiots... the ever-widening gap between people who know how to make movies and the people who greenlight the movies."^[277]

The superhero film genre experienced renewed and intense interest throughout the 2000s. With high ticket and DVD sales, several new superhero films were released every year. DC Comics and Marvel Comics feature full-length superhero films including Superman, Batman, Spider-Man and X-Men. Some media commentators attributed the increased popularity of such franchises to the social and political climate in Western society since the September 11th attacks,^[281] although others argued advances in special effects technology played a more significant role.^[282]

Animated films

The animated feature film market changed radically. Computer animated films became hugely popular following the release of Toy Story in the mid-1990s. After failures such as The Road to El Dorado, The Wild Thornberrys Movie, Rugrats Go Wild, Osmosis Jones, Hey Arnold!: The Movie and Looney Tunes: Back in Action, studios have stopped their production of traditional 2D animated films, and gradually changed their focus into CGI animation in the late 2000s. Traditional 2D animated films that did well in the first half of the decade include Rugrats in Paris: The Movie, Spirit: Stallion of the Cimarron, The SpongeBob SquarePants Movie, and Lilo & Stitch as well as anime films such as Studio Ghibli's Spirited Away, The Cat Returns, Howl's Moving Castle, and Ponyo.

Disney would begin making 3D animated films such as Dinosaur, Chicken Little, Meet the Robinsons, and Bolt as well as continuing to make traditional animated films from the past decades such as The Emperor's New Groove, Atlantis: The Lost Empire, Treasure Planet, Brother Bear, Home on the Range, and The Princess and the Frog. All of these films would underperform at the box office and receive adequate reviews although they would become cult classics.

Meanwhile, computer-animated films saw the rise of Pixar throughout the 2000s with their critically and commercially films like Monsters, Inc., Finding Nemo, The Incredibles, Cars, Ratatouille, WALL-E, and Up.

DreamWorks also began to take its rise albeit to a lesser extent as the 2003 movie Sinbad: Legend of the Seven Seas became the last traditional animated DreamWorks film. These films include Shrek, Shrek 2, Madagascar, Over the Hedge, Flushed Away, Shrek the Third, Bee Movie, Kung Fu Panda, Madagascar: Escape 2 Africa, and Monsters vs. Aliens.

20th Century Fox Animation's works in that decade include the Ice Age series, Robots and Horton Hears a Who! which were all made by its Blue Sky Studios subsidiary, and Titan A.E., Waking Life, The Simpsons Movie, and Fantastic Mr. Fox.

In 2006, Warner Bros. and Village Roadshow Pictures animated film Happy Feet.

Columbia Pictures and Sony Pictures Animation films such as Open Season, Surf's Up, and Cloudy with a Chance of Meatballs.

In 2009, computer-animated science fiction comedy film Planet 51.

Stop motion animated films in that decade which mostly use live-action or computer animation methods included Chicken Run, Team America: World Police, Wallace & Gromit: The Curse of the Were-Rabbit, Corpse Bride, Flushed Away, Coraline, and Mary and Max. Independent animated works in that decade included The Triplets of Belleville, Laura's Star, A Scanner Darkly, Renaissance, Persepolis, Sita Sings the Blues, The Secret of Kells and A Town Called Panic.

In the 2000s, the Internet allowed consumers unprecedented access to music. The Internet also allowed more artists to distribute music relatively inexpensively and independently without the previously necessary financial support of a record label. Music sales began to decline following the year 2000, a state of affairs generally attributed to unlicensed uploading and downloading of sound files to the Internet, a practice which became more widely prevalent during this time. Business relationships called 360 deals—an arrangement in which a company provides support for an artist, and, in exchange, the artist pays the company a percentage of revenue earned not only from sales of recorded music, but also live performances and publishing—became a popular response by record labels to the loss of music sales attributed to online copyright infringement.^[329][330]

Eminem (left) and Beyoncé were two of the best-selling musical artists and most-culturally significant figures of the decade, pictured here in 2003 and 2007 respectively.

Other popular hip hop artists included Jay-Z, Nas, Busta Rhymes, Kanye West, Ludacris, Common, Ja Rule, Mos Def, DMX, Missy Elliot, OutKast, Lil Jon, Fat Joe, Cam'ron, Pharrell, Gorillaz, Snoop Dogg, Twista, 50 Cent, Nelly, Lil Wayne, T.I., Young Jeezy and The Game. The genre was extremely diverse stylistically, including subgenres such as gangsta rap and crunk. Many hip hop albums were released to widespread critical acclaim.

R&B also gained prominence throughout the decade, and included artists such as D'Angelo, Aaliyah, Usher, Akon, Black Eyed Peas, R. Kelly, Amy Winehouse, Mary J. Blige, Jamie Foxx, Chris Brown, John Legend and Alicia Keys.

In alternative rock, the garage rock revival and post-punk revival entered the mainstream, with bands such as The Strokes, Interpol, The Killers, Arctic Monkeys, Bloc Party, Yeah Yeah Yeahs and The White Stripes seeing commercial success. Indie rock also saw a proliferation in the 2000s with numerous bands experiencing commercial success, including Modest Mouse, TV on the Radio, Franz Ferdinand, Death Cab for Cutie, Arcade Fire, Vampire Weekend, LCD Soundsystem, The Shins, Wilco, Bright Eyes, Spoon, The Decemberists, Broken Social Scene, Grizzly Bear, Fleet Foxes and many more.

It was also used in certain tracks off critically acclaimed 2001 albums from Daft Punk (with Discovery) and Radiohead (with Amnesiac).^[330] By 2008, auto-tune was part of the music mainstream with artists such as Lil Wayne, T-Pain and Kanye West utilizing it in their hit albums Tha Carter III, Three Ringz and 808s & Heartbreak respectively.
