The Strange Conservative Brain: 3 Reasons Republicans Refuse to Accept Reality About Global Warming | | AlterNet

So the question before us on this panel is, "Will the Planet Survive the Age of Humans?" And I want to focus on one particular aspect of humans that makes them very problematic in a planetary sense -- namely, their brains. What I've spent the last year or more trying to understand is what it is about our brains that makes facts such odd and threatening things; why we sometimes double down on false beliefs when they're refuted; and maybe, even, why some of us do it more than others.

And of course, the new book homes in on the brains — really, the psychologies — of politically conservative homo sapiens in particular. You know, Stephen Colbert once said that “reality has a well-known liberal bias.” And essentially what I’m arguing is that, not only is that a funny statement, it’s factually true, and perhaps even part of the nature of things.

Colbert also talked about the phenomenon of “truthiness,” and as it turns out, we can actually give a scientific explanation of truthiness — which is what I’m going to sketch in the next ten minutes, with respect to global warming in particular.

I almost called the book The Science of Truthiness — but The Republican Brain turns out to be a better title.

The Facts About Global Warming

So first off, let’s start with the facts about climate change — facts that you’d think (or you’d hope) any human being ought to accept.

It turns out that the case for human-caused global warming is based on simple and fundamental physics. We’ve known about the greenhouse effect for over one hundred years. And we’ve known that carbon dioxide is a heat trapping gas, a greenhouse gas. Some of the key experiments on this, by the Irishman John Tyndall, actually occurred in the year 1859, which is the same year that Darwin published On the Origin of Species.

We also know that if we do nothing, seriously bad stuff starts happening. If we melt Greenland and West Antarctica, we’re looking at 40 feet of sea level rise. This is, like, bye bye to key parts of Florida.
