Climatic Research Unit documents
Climatic Research Unit documents including thousands of e-mails and other computer files were stolen from a server at the Climatic Research Unit of the University of East Anglia in a hacking incident in November 2009. The documents were redistributed first through the blogosphere of global warming skeptics, and allegations were made that they indicated misconduct by leading climate scientists. A series of investigations rejected these allegations, while concluding that CRU scientists should have been more open with distributing data and methods on request. Precisely six committees investigated the allegations and published reports, finding no evidence of fraud or scientific misconduct. The scientific consensus that global warming is occurring as a result of human activity remained unchanged by the end of the investigations.The incident occurred shortly before the opening December 2009 Copenhagen global climate summit. It has prompted general discussion about increasing the openness of scientific data (though the majority of climate data have always been freely available). Scientists, scientific organisations, and government officials have stated that the incident does not affect the overall scientific case for climate change. Andrew Revkin reported in the New York Times that ""The evidence pointing to a growing human contribution to global warming is so widely accepted that the hacked material is unlikely to erode the overall argument.""
