The Tennessean has been publishing numerous letters to the editor and editorial columns talking about how "climategate" supposedly shows that anthropogenic global warming is a fraud. It's extremely frustrating. That conclusion can only be drawn from a deep misunderstanding about how science works and the language of scientists used in the e-mails, but sadly it seems that newspapers are interested more in presenting "both sides" than getting to the truth of it. Today, there is an egregious column from David Lipscomb professor Richard Grant repeats the same tired arguments global warming denialists have already been using, and completely misunderstands the impacts of the supposed revelations from the leaked University of East Anglia emails.
It's very frustrating myself to watch this happen. The people who are trumpeting about this are ignorant about science. When I read the excerpts from the emails that are supposedly the smoking gun about climate change being a fraud, I do not see anything extremely alarming. What's more, even if I did, the evidence for climate change has not come completely from the University of East Anglia; it has come from all over the place. If it hadn't, scientists would not be accepting it as strongly as they do! And, yet, the newspaper coverage of this is covering the scandal, the controversy... it does not seek to illuminate the truth of the situation, to explain what is really going on. And, this of course lends fuel to the politicians who are exploiting global warming denialism for their own ends. (To be fair, there are also politicians who exploit the fact of human-caused global warming for their own ends! That doesn't make the conclusions wrong, however.) It is sad to me to see so many in our population being manipulated in a way that will allow us as a society to act in ways that may very likely cause us tremendous pain in future decades.
Here is the text of a letter to the editor I wrote to the Tennessean in response. I don't know if it will get published; I hope it does, of course, because many more people read the Tennessean letters to the editor than this blog.
The numerous letters and columns that have been written suggesting that "climategate" undermines conclusions about anthropogenic global warming are all getting it very wrong. There are two important points.
First, no matter what the researchers said when venting frustrations in private e-mail, their final actions in what data was published showed no misconduct. Nothing was suppressed, nothing was fudged. The impact of the supposedly revealing emails is vastly overstated by those who deny man-made global warming.
Second, and perhaps more importantly, even if we throw out all of the climate data and conclusions from the researchers in question, the conclusions still stand. This is an important point about how science works. Cold Fusion generated a lot of headlines in the 1980's when first reported, but ultimately didn't stand because no independent scientists could reproduce the results. With climate change, there are multiple independent teams who have data that all point to the same conclusions. Even if something were to cast doubt on conclusions of the University of East Anglia, that does not in any way affect the independent data of the USA's NOAA, for example.
The climate change data is still robust. The leaked emails only show informal communication using the jargon scientists use, and normal human frustration with how obstinate so many seem to be against accepting the fact of man-made global warming. Given how science works, these emails do not in any way undermine those conclusions. It is only at our peril that we use these leaked emails to further political ends.
