It is becoming more and more clear that we can't fight catastrophic climate change unless we understand why we can't fight it. And this is a job that involves understanding how the human brain works (if it works!). Here is an excerpt from an article by psychologist Mary Pipher on Time Magazine that examines the question
I’ve learned not to argue too long with people who do not “believe in” human-made climate change. I figure it’s impossible to reason someone out of a position that they didn’t reason themselves into. But the fact is that even those of us who do believe climate change is man-made are in partial denial about our enormous global problems, and almost all of us minimize or normalize the situation.
Our denial is understandable. Our species is not equipped to respond to the threats posed by global warming. Humans are built to find food and shelter, reproduce, and enjoy each other. We are genetically programmed to react to threats by fleeing or fighting, and at first, our environmental crisis does not seem to allow us to do either. We’re better at dealing with problems that are concrete, close-at-hand, familiar and require skills and tools that we already possess. Our global storm is invisible, unprecedented, drawn out, and caused by all of us. We have Paleolithic arousal systems, Neolithic brains, medieval institutions and 21st century technology—not a good mix for solving our climate problems.
