Even if Bill McKibben were to become dictator, future generations would suffer because of the carbon we had already emitted.

I begin with human psychology and then see what we can say about ethics.

Many environmental questions are in a deep way philosophical, despite our penchant for treating them as if they were only technological, economic, or whatever.

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.

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.

'The anthropocene' refers to the way we live now, in a highly globalized world, characterized by a large human population and powerful technologies that allow for "action at a distance" that aggregate apparently negligible acts into powerful forces that are transforming fundamental planetary systems. In this sense 'the anthropocene' refers to a period in which nature as an independent autonomous domain comes to an end or is under serious threat.

Philosophy isn't reading Emmanuel Kant. Philosophy is about thinking hard about what the right thing to do is in a situation and approaching that kind of question in an open-minded and open-hearted way, receptive to a broad range of considerations and interests of other people and other things.
