Effects on pregnancy A February 2003 Danish study of 18,478 women linked heavy coffee consumption during pregnancy to significantly increased risk of stillbirths (but no significantly increased risk of infant death in the first year). "The results seem to indicate a threshold effect around four to seven cups per day," the study reported. Those who drank eight or more cups a day (64 U.S. fl oz or 1.89 L) were at 220% increased risk compared with nondrinkers. This study has not yet been repeated, but has caused some doctors to caution against excessive coffee consumption during pregnanc

The study concluded that consumption of coffee is associated with significant elevations in biochemical markers of inflammation. This is a detrimental effect of coffee on the cardiovascular system, which may explain why coffee has so far only been shown to help the heart at levels of four cups (24 fl oz or 600 mL) or fewer per day.[42]

Coffee intake may reduce one's risk of diabetes mellitus type 2 by up to half. While this was originally noticed in patients who consumed high amounts (7 cups a day), the relationship was later shown to be linear.[13][14]

Coffee consumption decreased risk of gout in men over age 40. In a large study of over 45,000 men over a 12-year period, the risk for developing gout in men over 40 was inversely proportional with the amount of coffee consumed.[32]

Over 1,000 chemicals have been reported in roasted coffee, and 19 are known rodent carcinogens;[33] however, most substances cited as rodent carcinogens occur naturally and should not be assumed to be carcinogenic in humans at exposure levels typically experienced in day-to-day life.

Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs and nitrous oxide. The concentrations of CO2 and methane have increased by 36% and 148% respectively since the mid-1700s.[23] These levels are much higher than at any time during the last 650,000 years, the period for which reliable data has been extracted from ice cores.[24] Less direct geological evidence indicates that CO2 values this high were last seen about 20 million years ago.[25] Fossil fuel burning has produced about three-quarters of the increase in CO2 from human activity over the past 20 years. Most of the rest is due to land-use change, particularly deforestation.[26]

If the atmosphere is warmed, the saturation vapor pressure increases, and the amount of water vapor in the atmosphere will tend to increase. Since water vapor is a greenhouse gas, the increase in water vapor content makes the atmosphere warm further; this warming causes the atmosphere to hold still more water vapor (a positive feedback), and so on until other processes stop the feedback loop

When ice melts, land or open water takes its place. Both land and open water are on average less reflective than ice and thus absorb more solar radiation. This causes more warming, which in turn causes more melting, and this cycle continues.

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century.

Temperature changes vary over the globe. Since 1979, land temperatures have increased about twice as fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade).

The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation.

Warming is expected to change the distribution and type of clouds. Seen from below, clouds emit infrared radiation back to the surface, and so exert a warming effect; seen from above, clouds reflect sunlight and emit infrared radiation to space, and so exert a cooling effect.

Geoengineering is the deliberate modification of Earth's natural environment on a large scale to suit human needs.[106] An example is greenhouse gas remediation, which removes greenhouse gases from the atmosphere, usually through carbon sequestration techniques such as carbon dioxide air capture.

Measures including water conservation,[100] water rationing, adaptive agricultural practices,[101] construction of flood defences,[102] Martian colonization,[103] changes to medical care,[104] and interventions to protect threatened species[105] have all been suggested. A wide-ranging study of the possible opportunities for adaptation of infrastructure has been published by the Institute of Mechanical Engineers.

After the decisive military defeat, the agreement to a ceasefire on February 28, and political maneuvering, the UN Security Council continued to press its demands that Hussein accept previous UN Security Council Resolutions, as stated in UNSCR 686. By April, UNSCR 687 recognized Kuwait's sovereignty had been reinstated, and established the United Nations Special Commission on Iraq (UNSCOM). Two days later, UNSCR 688 added that Iraq must cease violent repression of ethnic and religious minorities. The aftermath of the war saw the Iraqi military, especially its air force, destroyed. In return for peace, Iraq was forced to dismantle all chemical and biological weapons it possessed, and end any attempt to create or purchase nuclear weapons, to be assured by the allowing UN weapons inspectors to evaluate the dismantlement of such weapons. Finally, Iraq would face sanctions if it disobeyed any of the demands. Shortly after the war ended in 1991, Shia Muslim and Kurdish Iraqis engaged in protests against Hussein's regime, resulting in an intifada. Hussein responded with violent repression against Shia Muslims, and the protests came to an end.[41] It is estimated that as many as 100,000 people were killed.[42] The US, UK, France and Turkey claiming authority under UNSCR 688, established the Iraqi no-fly zones to protect Kurdish and Shiite populations from attacks by the Hussein regime's aircraft.

Disarmament crisis Main article: Iraq disarmament crisis While Iraq had agreed to UNSCR 687, the Iraqi government sometimes worked with inspectors, but ultimately failed to comply with disarmament terms, and as a result, economic sanctions against Iraq continued. After the war, Iraq was accused of breaking its obligations throughout the 1990s, including the discovery in 1993 of a plan to assassinate former President George H. W. Bush, and the withdrawal of Richard Butler's UNSCOM weapon inspectors in 1998 after the Iraqi government claimed some inspectors were spies for the U.S. Central Intelligence Agency.[43] On multiple occasions throughout the disarmament crisis, the UN passed further resolutions (see United Nations Resolutions concerning Iraq) compelling Iraq to comply with the terms of the ceasefire resolutions. It is estimated more than 500,000 Iraqi children died as a result of the sanctions.[44][45] With humanitarian and economic concerns in mind, UNSCR 706 and UNSCR 712 allowed Iraq to sell oil in exchange for humanitarian aid. This was later turned into the Oil-for-Food Programme by UNSCR 986. Over the years, U.S. land forces were deployed to the Iraq border, and U.S. bombings were carried out to try to pressure Hussein to comply with UN resolutions. As a result of these repeated violations, US Secretary of State Madeline Albright, US Secretary of Defense William Cohen, and US National Security Advisor Sandy Berger held an international town hall meeting to discuss possible war with Iraq, which seemed to have little public support. In October 1998, U.S. President Bill Clinton signed the Iraq Liberation Act, calling for "regime change" in Iraq, and initiated Operation Desert Fox. Following Operation Desert Fox, and end to partial cooperation from Iraq prompted UNSCR 1284, disbanding UNSCOM and replacing it with United Nations Monitoring, Verification and Inspection Commission (UNMOVIC).

The Bush administration made a number of allegations against Iraq, including that Iraq was acquiring uranium from Niger and that Iraq had secret weapons laboratories in trailers and isolated facilities throughout Iraq;[citation needed] none of these allegations have proven true. Saddam Hussein, under pressure from the U.S. and the U.N., finally agreed to allow weapons inspectors to return to Iraq in 2002, but by that time the Bush administration had already begun pushing for war. In June 2002, Operation Southern Watch transitioned to Operation Southern Focus, bombing sites around Iraq. The first CIA team entered Iraq on July 10, 2002. This team was composed of elite CIA Special Activities Division and the U.S. Military's elite Joint Special Operations Command (JSOC) operators. Together, they prepared the battle space of the entire country for conventional U.S. Military forces. Their efforts also organized the Kurdish Peshmerga to become the northern front of the invasion and eventually defeat Ansar Al-Islam in Northern Iraq before the invasion and Saddam's forces in the north. The battle led to the killing of a substantial number of terrorists and the uncovering of a chemical weapons facility at Sargat.[46][47] In October 2002, the U.S. Congress passed the Joint Resolution to Authorize the Use of United States Armed Forces Against Iraq, and in November the UN Security Council passes UNSCR 1441.

Invasion and civil war Main article: 2003 invasion of Iraq Further information: Iraq War On March 20, 2003, a United States-organized coalition invaded Iraq, with the stated reason that Iraq had failed to abandon its nuclear and chemical weapons development program in violation of U.N. Resolution 687. The United States asserted that because Iraq was in material breach of Resolution 687, the armed forces authorization of Resolution 678 was revived. The United States further justified the invasion by claiming that Iraq had or was developing weapons of mass destruction and stating a desire to remove an oppressive dictator from power and bring democracy to Iraq. In his State of the Union Address on January 29, 2002, President George W. Bush declared that Iraq was a member of the "Axis of Evil", and that, like North Korea and Iran, Iraq's attempt to acquire weapons of mass destruction posed a serious threat to U.S. national security. These claims were based on documents that were provided to him by the CIA and the government of the United Kingdom.[48] Bush added, Iraq continues to flaunt its hostilities toward America and to support terror. The Iraqi regime has plotted to develop anthrax, and nerve gas, and nuclear weapons for over a decade... This is a regime that agreed to international inspections — then kicked out inspectors. This is a regime that has something to hide from the civilized world... By seeking weapons of mass destruction, these regimes [Iran, Iraq and North Korea] pose a grave and growing danger. They could provide these arms to terrorists, giving them the means to match their hatred.[49] However, according to a comprehensive U.S. government report, no complete, fully functional weapons of mass destruction have been found since the invasion.[50] There are accounts of Polish troops obtaining antiquated warheads, dating from the 1980s, two of which contained trace amounts of the nerve gas cyclosarin, but U.S. military tests found that the rounds were so deteriorated that they would "have limited to no impact if used by insurgents against coalition forces." [51][52][53][54][55][56] Iraq was also home to 1.8 tons of low-enriched uranium, miscellaneous other nuclear materials, and chemical weapons paraphernalia; the nuclear material was under the supervision of the IAEA until the beginning of the war.

Post-invasion Main articles: Post-invasion Iraq, 2003–present, Insurgency in Iraq, Civil war in Iraq, and Humanitarian Crises of the Iraq War Occupation zones in Iraq after invasion. Following the invasion, the United States established the Coalition Provisional Authority to govern Iraq.[57] Government authority was transferred to an Iraqi Interim Government in June 2004, and a permanent government was elected in October 2005. More than 140,000 troops, mainly Americans, remain in Iraq. Some studies have placed the number of civilians deaths as high as 655,000 (see The Lancet study), although most studies estimate a lower number; the Iraq Body Count project indicates a significantly lower number of civilian deaths than that of The Lancet Study, though IBC organizers acknowledge that their statistics are an undercount as they base their information off of media-confirmed deaths. The website of the Iraq body count states, "Our maximum therefore refers to reported deaths – which can only be a sample of true deaths unless one assumes that every civilian death has been reported. It is likely that many if not most civilian casualties will go unreported by the media."[58] After the invasion, al-Qaeda took advantage of the national resistance to entrench itself in the country. On December 30, 2006, Saddam Hussein was hanged.[59] Hussein's half-brother and former intelligence chief Barzan Hassan and former chief judge of the Revolutionary Court Awad Hamed al-Bandar were likewise executed on January 15, 2007;[60] as was Taha Yassin Ramadan, Saddam's former deputy and former vice-president (originally sentenced to life in prison but later to death by hanging), on March 20, 2007.[61] Ramadan was the fourth and last man in the al-Dujail trial to die by hanging for crimes against humanity. President of Iraq Jalal Talabani with U.S. President Barack Obama in 2009. At the Anfal genocide trial, Saddam's cousin Ali Hassan al-Majid (aka Chemical Ali), former defense minister Sultan Hashim Ahmed al-Tay, and former deputy Hussein Rashid Mohammed were sentenced to hang for their role in the Al-Anfal Campaign against the Kurds on June 24, 2007.[citation needed] Al-Majid was sentenced to death three more times: once for the 1991 suppression of a Shi'a uprising along with Abdul-Ghani Abdul Ghafur on December 2, 2008;[62] once for the 1999 crackdown in the assassination of Grand Ayatollah Mohammad al-Sadr on March 2, 2009;[63] and once on January 17, 2010 for the gassing of the Kurds in 1988;[64] he was hanged over a week later on January 25.[65] Acts of sectarian violence have led to claims of ethnic cleansing in Iraq, and there have been many attacks on Iraqi minorities such as the Yezidis, Mandeans, Assyrians and others.[66] A U.S. troop surge to deal with increased violence and improve security became a contentious political issue in the United States. The surge in troops was enacted in early 2007; in his September 2007 testimony to Congress, General Petraeus stated that the surge's goals were being met.[67] Iraq also suffered a cholera outbreak in 2007.[68]

On June 29, 2009, U.S. troops formally withdrew from Baghdad streets, in accordance with former U.S. President George W. Bush's security pact with Iraq known as the Status of Forces Agreement. The SOFA pact stated, among other things, that U.S. troops will withdraw from Iraq's cities by June 30, 2009, and will leave the country on Dec. 31, 2011.[70] Throughout the country, as the citizens of Iraq celebrated with fireworks,[71] television programs declared June 30 as National Sovereignty Day.[72][73] However, crime and violence initially spiked in the months following the US withdra

Independently, in 1996, structures resembling nanobacteria were reportedly discovered in a meteorite, ALH84001, thought to be formed of rock ejected from Mars. This report is also controversial, and scientific debate continues.

Within Islam, the statement of the Qur'an "All praise belongs to God, Lord of all the worlds" indicates multiple universal bodies, and maybe even multiple universes, which may indicate extraterrestrial and even extradimensional life. Surat Al-Jinn also mentioned a statement from a Jinn regarding the current status and ability of his group in the heavens.

The other large moons of our system which have been visited appear similarly lifeless, though the interesting geothermic forces observed (Io's volcanism, Europa's ocean, Titan's thick atmosphere) have underscored how broad the range of potentially habitable environments may be.
