The scientific consensus on global warming was undermined by “Climategate”
The “Climategate” allegations were disproven by six official investigations
In November 2009, emails were stolen from a server at the Climatic Research Unit at the University of East Anglia in the United Kingdom. Climate change deniers twisted contents of the emails to suggest they showed that climate scientists had manipulated data to exaggerate the threat of global warming. Ultimately, these allegations were thoroughly disproven.
The Union of Concerned Scientists notes that “six official investigations have cleared scientists of accusations of wrongdoing.” The organization lists the investigations:
A three-part Penn State University cleared scientist Michael Mann of wrongdoing.
Two reviews commissioned by the University of East Anglia "supported the honesty and integrity of scientists in the Climatic Research Unit."
A UK Parliament report concluded that the emails have no bearing on our understanding of climate science and that claims against UEA scientists are misleading.
The National Oceanic and Atmospheric Administration Inspector General's office concluded there was no evidence of wrongdoing on behalf of their employees.
The National Science Foundation's Inspector General's office concluded, "Lacking any direct evidence of research misconduct...we are closing this investigation with no further action."
