Six committees investigated the allegations and published reports, finding no evidence of fraud or scientific misconduct. The Muir Russell report stated, however, "We do find that there has been a consistent pattern of failing to display the proper degree of openness, both on the part of CRU scientists and on the part of the UEA." The scientific consensus that global warming is occurring as a result of human activity remained unchanged at the end of the investigations.

Timeline of the initial incident

The incident began when someone accessed a server used by the Climatic Research Unit and copied 160 MB

.

Most of the emails concerned technical and mundane aspects of climate research, such as data analysis and details of scientific conferences. The Guardian's analysis of the emails suggests that the hacker had filtered them. Four scientists were targeted and a concordance plot shows that the words "data", "climate", "paper", "research", "temperature" and "model" were predominant. The controversy has thus focused on a small number of emails. Skeptic websites picked out particular phrases, including one in which Kevin Trenberth stated, "The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t". This was actually part of a discussion on the need for better monitoring of energy flows involved in short-term climate variability, but was grossly mischaracterised by critics.

 as though they referred to a decline in measured global temperatures, even though they were written when temperatures were at a record high. John Tierney, writing in the New York Times in November 2009, said that the claims by sceptics of "hoax" or "fraud" were incorrect, but the graph on the cover of a report for policy makers and journalists did not show these non-experts where proxy measurements changed to measured temperatures. The final analyses from various subsequent inquiries concluded that in this context 'trick' was normal scientific or mathematical jargon for a neat way of handling data, in this case a statistical method used to bring two or more different kinds of data sets together in a legitimate fashion. The EPA notes that in fact, the evidence shows that the research community was fully aware of these issues and was not hiding or concealing them.

He is a valued and important scientist." The university announced it would conduct an independent review to "address the issue of data security, an assessment of how we responded to a deluge of Freedom of Information requests, and any other relevant issues which the independent reviewer advises should be addressed."

The university announced on 1 December that Phil Jones was to stand aside as director of the Unit until the completion of the review. Two days later, the university announced that Sir Muir Russell

The review would also scrutinise the CRU's policies and practices for "acquiring, assembling, subjecting to peer review, and disseminating data and research findings" and "their compliance or otherwise with best scientific practice". In addition, the investigation would review CRU's compliance with Freedom of Information Act requests and also "make recommendations about the management, governance and security structures for CRU and the security, integrity and release of the data it holds." The Independent Climate Change E-mails Review report was published on 7 July 2010.

On 22 March 2010 the university announced the composition of an independent Science Assessment Panel to reassess key CRU papers which have already been peer reviewed and published in journals.

She hoped that the affair would change the approach of scientists to providing their data to the public, and their response to criticisms of their work. She had herself learned to be careful about what to put in emails when a "disgruntled employee" made a freedom of information request. Mann described these comments as "somewhat naive" considering that in recent years scientists had become much more open with their data. He said that sceptics "will always complain about something else, want something more. Eventually, as we see, they've found a way to get access to private communications between scientists."

On 5 December 2009, however, the Met Office indicated its intention to re-examine 160 years of temperature data in the light of concerns that public confidence in the science had been damaged by the controversy over the emails. The Met Office would also publish online the temperature records for over 1,000 worldwide weather stations. It remained confident that its analysis would be shown to be correct and that the data would show a temperature rise over the past 150 years.

 and other interested parties. An oral evidence session was held on 1 March 2010.

The Science and Technology Select Committee inquiry reported on 31 March 2010 that it had found that "the scientific reputation of Professor Jones and CRU remains intact". The emails and claims raised in the controversy did not challenge the scientific consensus that "global warming is happening and that it is induced by human activity". The MPs had seen no evidence to support claims that Jones had tampered with data or interfered with the peer-review process.

The committee criticised a "culture of non-disclosure at CRU" and a general lack of transparency in climate science where scientific papers had usually not included all the data and code used in reconstructions. It said that "even if the data that CRU used were not publicly available—which they mostly are—or the methods not published—which they have been—its published results would still be credible: the results from CRU agree with those drawn from other international data sets; in other words, the analyses have been repeated and the conclusions have been verified." The report added that "scientists could have saved themselves a lot of trouble by aggressively publishing all their data instead of worrying about how to stonewall their critics." The committee criticised the university for the way that freedom of information requests were handled, and for failing to give adequate support to the scientists to deal with such requests.

 said that the "standard practice" in climate science generally of not routinely releasing all raw data and computer codes "needs to change and it needs to change quickly". Jones had admitted sending "awful emails"; Willis commented that "[Jones] probably wishes that emails were never invented," but "apart from that we do believe that Prof. Jones has in many ways been scapegoated as a result of what really was a frustration on his part that people were asking for information purely to undermine his research." In Willis' view this did not excuse any failure to deal properly with FOI Act requests, but the committee accepted that Jones had released all the data that he could. It stated: "There is no reason why Professor Jones should not resume his post. He was certainly not co-operative with those seeking to get data, but that was true of all the climate scientists".

The committee was careful to point out that its report had been written after a single day of oral testimony and would not be as in-depth as other inquiries.

Science Assessment Panel

The report of the independent Science Assessment Panel was published on 14 April 2010 and concluded that the panel had seen "no evidence of any deliberate scientific malpractice in any of the work of the Climatic Research Unit." It found that the CRU's work had been "carried out with integrity" and had used "fair and satisfactory" methods. The CRU was found to be "objective and dispassionate in their view of the data and their results, and there was no hint of tailoring results to a particular agenda." Instead, "their sole aim was to establish as robust a record of temperatures in recent centuries as possible."

The panel commented that it was "very surprising that research in an area that depends so heavily on statistical methods has not been carried out in close collaboration with professional statisticians." It found that although the CRU had not made inappropriate use of statistical methods, some of the methods used may not have been the best for the purpose, though it said that "it is not clear, however, that better methods would have produced significantly different results." It suggested that the CRU could have done more to document and archive its work, data and algorithms and stated that the scientists were "ill prepared" for the amount of public attention generated by their work, commenting that "as with many small research groups their internal procedures were rather informal." The media and other scientific organisations were criticised for having "sometimes neglected" to reflect the uncertainties, doubts and assumptions of the work done by the CRU. The UK Government's policy of charging for access to scientific data was described as "inconsistent with policies of open access to data promoted elsewhere." The panel was also stated that "Although we deplore the tone of much of the criticism that has been directed at CRU, we believe that this questioning of the methods and data used in dendroclimatology will ultimately have a beneficial effect and improve working practices." It found that some of the criticism had been "selective and uncharitable" and critics had displayed "a lack of awareness" of the difficulties of research in this area.

Speaking at a press conference to announce the report, the panel's chair, Lord Oxburgh, stated that his team had found "absolutely no evidence of any impropriety whatsoever" and that "whatever was said in the emails, the basic science seems to have been done fairly and properly." He said that many of the criticisms and allegations of scientific misconduct had been made by people "who do not like the implications of some of the conclusions" reached by the CRU's scientists. The repeated FOI requests made by climate change sceptic Steve McIntyre and others "could have amounted to a campaign of harassment" and the issue of how FOI laws should be applied in an academic context remained unresolved. Another panel member, Professor David Hand, commended the CRU for being explicit about the inherent uncertainties in its research data, commenting that "there is no evidence of anything underhand – the opposite, if anything, they have brought out into the open the uncertainties with what they are dealing with."

The UEA's vice-chancellor, Edward Acton, welcomed the panel's findings. Describing its report as "hugely positive", he stated that "it is especially important that, despite a deluge of allegations and smears against the CRU, this independent group of utterly reputable scientists have concluded that there was no evidence of any scientific malpractice." He criticised the way that the emails had been misrepresented, saying that "UEA has already put on record its deep regret and anger that the theft of emails from the University, and the blatant misrepresentation of their contents as revealed both in this report and the previous one by the Science and Technology Select Committee, damaged the reputation of UK climate science." The UEA issued a statement in which it accepted that "things might have been done better." It said that improvements had already been undertaken by the CRU and others in the climate science community and that the University would "continue to ensure that these imperatives are maintained."

It later emerged that the Science Assessment Panel was not assessing the quality but instead the integrity of the CRU's science. Phil Willis described this a "sleight of hand" and was not what the Parliamentary Committee he had chaired had been led to believe. There were also questions about the selection of publications examined by the panel. Lord Oxburgh said that Acton had been wrong to tell the Science and Technology Select Committee in March that his inquiry would look into the science itself. "I think that was inaccurate," Oxburgh said. "This had to be done rapidly. This was their concern. They really wanted something within a month. There was no way our panel could evaluate the science."

, or misused privileged or confidential information. The committee did not make a definitive finding on the final point of inquiry — "whether Dr. Mann seriously deviated from accepted practices within the academic community for proposing, conducting, or reporting research or other scholarly activities". The committee said that the earlier NAS inquiry had found "that Dr. Mann’s science did fall well within the bounds of accepted practice", but in light of the newly available information this question of conduct was to be investigated by five prominent Penn State scientists from other scientific disciplines.

The Investigatory Committee reported on 4 June 2010 that it had "determined that Dr. Michael E. Mann did not engage in, nor did he participate in, directly or indirectly, any actions that seriously deviated from accepted practices within the academic community." Regarding his sharing unpublished manuscripts with colleagues on the assumption of implied consent, it considered such sharing to be "careless and inappropriate" without following the best practice of getting express consent from the authors in advance, though expert opinion on this varied. It said that his success in proposing research and obtaining funding for it, commenting that this "clearly places Dr. Mann among the most respected scientists in his field. Such success would not have been possible had he not met or exceeded the highest standards of his profession for proposing research." Mann's extensive recognitions within the research community demonstrated that "his scientific work, especially the conduct of his research, has from the beginning of his career been judged to be outstanding by a broad spectrum of scientists." It agreed unanimously that "there is no substance" to the allegations against Mann.

Mann said he regretted not objecting to a suggestion from Jones in a 29 May 2008 message that he destroy emails. "I wish in retrospect I had told him, 'Hey, you shouldn't even be thinking about this,'" Mann said in March 2010. "I didn't think it was an appropriate request." Mann's response to Jones at the time was that he would pass on the request to another scientist. "The important thing is, I didn't delete any emails. And I don't think [Jones] did either."

Independent Climate Change Email Review

First announced in December 2009, a British investigation commissioned by the UEA and chaired by Sir Muir Russell, published its final report in July 2010. The commission cleared the scientists and dismissed allegations that they manipulated their data. The "rigour and honesty" of the scientists at the Climatic Research Unit were found not to be in doubt. The panel found that they did not subvert the peer review process to censor criticism as alleged, and that the key data needed to reproduce their findings was freely available to any "competent" researcher.

The panel did rebuke the CRU for their reluctance to release computer files, and found that a graph produced in 1999 was "misleading," though not deliberately so as necessary caveats had been included in the accompanying text. It found evidence that emails might have been deleted in order to make them unavailable should a subsequent request be made for them, though the panel did not ask anyone at CRU whether they had actually done this.

At the conclusion of the inquiry, Jones was reinstated with the newly created post of Director of Research.

, observed that in the aftermath of the "climategate" investigations, "the vindication of the climate scientists has received very little coverage at all. Vindication is not as sexy as accusation, and many people are still suspicious. After all, some of those emails, taken out of context, sounded damning. But what they show is that climate scientists are frustrated, because for two decades they have been under attack."

, also observed what appeared to be an organised effort to discredit climate science. Royce described "climategate" as "a sustained and coordinated campaign" aimed at undermining the credibility of the science, and disproportionate reporting of the original story "widely amplified by climate deniers", with much less coverage of reports that had cleared the scientists.

, professor of communication, political science and psychology at Stanford University, said scientists were overreacting. Referring to his own poll results of the American public, he said "It's another funny instance of scientists ignoring science." Krosnick found that "Very few professions enjoy the level of confidence from the public that scientists do, and those numbers haven't changed much in a decade. We don't see a lot of evidence that the general public in the United States is picking up on the (University of East Anglia) emails. It's too inside baseball."

The Christian Science Monitor, in an article titled "Climate scientists exonerated in 'climategate' but public trust damaged," stated, "While public opinion had steadily moved away from belief in man-made global warming before the leaked CRU emails, that trend has only accelerated." Paul Krugman

 Project on Climate Change, and colleagues found in 2010 that:
Climategate had a significant effect on public beliefs in global warming and trust in scientists. The loss of trust in scientists, however, was primarily among individuals with a strongly individualistic worldview or politically conservative ideology. Nonetheless, Americans overall continue to trust scientists more than other sources of information about global warming.

Further release, 2011

Another set of 5,000 emails, apparently copied at the same time as those previously released, was put on a Russian server, together with a message giving some selective quotations highlighting many of the issues raised previously, and links to this were posted on skeptic blogs on 22 November 2011. A small sample examined by the university "appears to be genuine." "As in 2009, extracts from emails have been taken completely out of context," UEA stated.
