Randi, skepticism, and global warming

Posted in Bad Astronomy by Skepdude on December 17, 2009


Yesterday, James Randi posted an entry on the JREF’s Swift blog about global warming. In it, he expressed some doubt over the consensus that humans are causing global warming. He does not doubt that warming is happening, as he made clear, just the role of humans in that change.

Unfortunately, one source he used in his essay was the Petition Project. This was an attempt by global warming denialists to muddy the climate issue, and one that has been thoroughly trashed — it’s really just as awful as the similarly ridiculous, and just as thoroughly nonsensical, attempt by the Discovery Institute to get a petition by scientists who doubt evolution. Randi also made a claim about the complexity of global warming, and how difficult it is to model, casting some uncertainty on it. As he said, this makes it very difficult for someone not well-versed in the field to come to a well-informed decision on climate change.

I was unaware that Randi had just posted his essay when, yesterday, I wrote a post asking for donations to the JREF. Obviously, the comments focused on Randi’s post. While some were fair, I was taken aback by the vitriol of many of the comments; some people were out-and-out calling Randi a denialist, which is ridiculous. Other comments were worse.

Needless to say, this made quite a splash in the skeptical blogosphere as well. Posts and comments sprouted up everywhere about it. Some were thoughtful, others, um, not so much. I was surprised by how many skeptics were quick to vilify Randi, again accusing him of being a global warming denialist. I got emails from people fearing for the skeptical movement as a whole!

Instead of rending my garments over this, I read Randi’s post carefully, and then sent him a note outlining why the Petition Project is a crock, as well as saying that yes, mathematical models of climate are very complex, but that doesn’t change observations indicating the reality of global warming or our role in it. Randi told me he was writing a followup, so I decided not to say anything about it here until his new post went up. I wanted to make sure I had all the facts before commenting.

Randi posted that followup blog entry today. As I expected, he took the new information into account, admitting that he was unaware of the dubious nature of the petition, and re-affirming that he is not denying global warming is occurring.
