Philosophers are often actively disinterested in what happens between the cup and the lips (after all, that's "non-ideal theory").

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.

In this era of globalization we are witnessing struggles within individual states about what their identity and interests consist in.

If you have a flat, fixed view of state interest then it is difficult to understand why some states adopt aggressive climate change policies, even when that risks economically disadvantaging them, and other states do not even when it would be in their economic interests to do so.

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.

People will suffer and so will nature, but life is likely to go on with a great deal of loss and mourning. Human adaptability and resilience will still be alive, and so will that great need and resource of ours called love.

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