It's true that climate change is an unprecedented problem so it's not surprising that it's so difficult to address.

Philosophers are smart, analytical, and skeptical. For these reasons they are relatively unbiased.

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.

Climate change involves fundamental choices about how we want to live and what kind of world we want.

Well, one measure of a good life, I think, is to be engaged in projects that one thinks are meaningful and worthwhile. So I would put the emphasis of a good life on activity, on the walk rather than the destination, and I think that most of the things that any of us do that are really valuable and really important are projects that we really shouldn't expect to be completed in our lifetime because if they could completed in our lifetime, they probably wouldn't be so important that we should devote our lives to them.

Ethical systems are fundamentally conservative and primarily directed towards regulating interactions within communities.

I think when it comes to climate change, the single most important thing in the world is for the United States' Congress to pass an effective bill that will put a price in carbon because if it starts costing something to emit carbon, this will provide an incentive, people do act on the basis to some extent of economic incentives to emit fewer greenhouse gases.
