Scientific consensus on climate change <=SEP=> There is currently a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. This consensus is supported by various studies of scientists' opinions and by position statements of scientific organizations, many of which explicitly agree with the Intergovernmental Panel on Climate Change (IPCC) synthesis reports.  Nearly all actively publishing climate scientists (97–98%) support the consensus on anthropogenic climate change, and the remaining 2% of contrarian studies either cannot be replicated or contain errors.

2009 United Nations Climate Change Conference <=SEP=> The 2009 United Nations Climate Change Conference , commonly known as the Copenhagen Summit , was held at the Bella Center in Copenhagen , Denmark , between 7 and 18 December . The conference included the 15th Conference of the Parties ( COP 15 ) to the United Nations Framework Convention on Climate Change ( UNFCCC ) and the 5th Meeting of the Parties ( MOP 5 ) to the Kyoto Protocol . According to the Bali Road Map , a framework for climate change mitigation beyond 2012 was to be agreed there .   On Friday 18 December , the final day of the conference , international media reported that the climate talks were `` in disarray '' . Media also reported that in lieu of a summit collapse , only a `` weak political statement '' was anticipated at the conclusion of the conference . The Copenhagen Accord was drafted by the United States , China , India , Brazil and South Africa on 18 December , and judged a `` meaningful agreement '' by the United States government . It was `` taken note of '' , but not `` adopted '' , in a debate of all the participating countries the next day , and it was not passed unanimously . The document recognised that climate change is one of the greatest challenges of the present day and that actions should be taken to keep any temperature increases to below 2 ° C . The document is not legally binding and does not contain any legally binding commitments for reducing emissions .   In January 2014 , documents leaked by Edward Snowden and published by Dagbladet Information revealed that the US government negotiators were in receipt of information during the conference that was being obtained by spying against other conference delegations . The US National Security Agency provided US delegates with advance details other delegations ' positions , including the Danish plan to `` rescue '' the talks should they flounder . Members of the Danish negotiating team said that both the US and Chinese delegations were `` peculiarly well-informed '' about closed-door discussions : `` They simply sat back , just as we had feared they would if they knew about our document . ''

Climatic Research Unit email controversy <=SEP=> The Climatic Research Unit email controversy ( also known as `` Climategate '' ) began in November 2009 with the hacking of a server at the Climatic Research Unit ( CRU ) at the University of East Anglia ( UEA ) by an external attacker , copying thousands of emails and computer files , the Climatic Research Unit documents , to various internet locations several weeks before the Copenhagen Summit on climate change .   The story was first broken by climate change denialists with columnist James Delingpole popularising the term `` Climategate '' to describe the controversy . Several people considered climate change `` skeptics '' argued that the emails showed global warming was a scientific conspiracy , that scientists manipulated climate data and attempted to suppress critics . The CRU rejected this , saying the emails had been taken out of context and merely reflected an honest exchange of ideas .   The mainstream media picked up the story as negotiations over climate change mitigation began in Copenhagen on 7 December 2009 . Because of the timing , scientists , policy makers and public relations experts said that the release of emails was a smear campaign intended to undermine the climate conference . In response to the controversy , the American Association for the Advancement of Science ( AAAS ) , the American Meteorological Society ( AMS ) and the Union of Concerned Scientists ( UCS ) released statements supporting the scientific consensus that the Earth 's mean surface temperature had been rising for decades , with the AAAS concluding , `` based on multiple lines of scientific evidence that global climate change caused by human activities is now underway ... it is a growing threat to society . ''   Eight committees investigated the allegations and published reports , finding no evidence of fraud or scientific misconduct . However , the reports called on the scientists to avoid any such allegations in the future by taking steps to regain public confidence in their work , for example by opening up access to their supporting data , processing methods and software , and by promptly honouring freedom of information requests . The scientific consensus that global warming is occurring as a result of human activity remained unchanged throughout the investigations .
