In 2009, an anonymous hacker posted more than 1,000 e-mails from the University of East Anglia on the Web, sparking a controversy dubbed “Climate-gate” by some media outlets and prompting many conservatives in the United States and elsewhere to question whether human activity induces global warming. British police have investigated the e-mail piracy but have yet to identify who was behind it.
Those e-mails painted the scientific climate establishment as combative and clubby, but a half-dozen investigations in the United States and Britain found no evidence that the scientists had manipulated data, as critics alleged.
This second batch deals less with climate science than with how some prominent scientists framed the issue and recruited colleagues to serve on panels such as the U.N. Intergovernmental Panel on Climate Change (IPCC).
In a statement Tuesday, the University of East Anglia said that “we have no evidence of a recent breach of our systems” and that it could not confirm yet whether the 5,000 new e-mails are genuine because of “the sheer volume of material.”
But it added that, if authentic, “these emails have the appearance of having been held back after the theft of data and emails in 2009 to be released at a time designed to cause maximum disruption to the imminent international climate talks. This appears to be a carefully-timed attempt to reignite controversy over the science behind climate change when that science has been vindicated by three separate independent inquiries and [a] number of studies — including, most recently, the Berkeley Earth Surface Temperature group.”
Jonathan Overpeck, who co-directs the Institute of the Environment at the University of Arizona and whose comments are quoted in the recent batch of e-mails, said this round “seems to be more of the same, and the conclusion will be the same, which is nothing was done wrong.” He added that when he and other researchers were writing e-mails several years ago, “no one was thinking, ‘What if these get stolen and get taken out of context — how will they sound?’ ”
In one set of e-mails from 2005, researchers discuss whether an early draft of a 2007 IPCC report accurately depicted the temperature rise in the lower atmosphere. An official from the British Met Office, a scientific organization that analyzes the climate, writes to the Climate Research Unit’s then-director, Phil Jones: “Observations do not show rising temperatures throughout the tropical troposphere unless you accept one single study and approach and discount a wealth of others. This is just downright dangerous. We need to communicate the uncertainty and be honest. Phil, hopefully we can find time to discuss these further if necessary.”
