A great deal of our math, science, philosophy, and everyday behavior presupposes that stability and equilibria are the "default" states, and everything else involves some "perturbation." This is a mental model, a conceptual frame, a tacit belief, a presupposition - whatever you want to call it.

When I first started studying climate change back in the 1980s, I was struck by how difficult it was be for people to understand this issue.

I became religious and at 14 went to a boarding school 500 miles from home to begin theological studies. By the time I started university, politics had replaced religion in the economy of my enthusiasms but I had no idea what to study. My boarding school emphasized languages which I was bad at, and deemphasized math and science which I was good at.

If you look at the works psychologists have done about individual reports of wellbeing, what happens is that if you're poor, you are not happy. But once you achieve a certain level of material satisfaction then income has very little correlation with people's reported states of happiness, things like climate matter more, things like the culture of the country in which you're raised matter more and so the things really, let's face it, like individual temperament matter more than these things.

Since we're not very good at something as basic as controlling our reproduction, life is really bad for more people than ever before.

Our traditional systems of decision-making are just not up to preventing changes in fundamental earth systems that are driven by a constant barrage of individually negligible emissions of an invisible, odorless gas, by billions of people all over the world.
