Climate scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.

Most "process" philosophy is historicist (e.g., Hegel) and not concerned with "deep time." Maybe Whitehead is an exception. He may be a really important philosopher for all I know. I've never been able to read him.

The density of human population combined with the development of powerful and largely unconstrained technology has given us the problems of the anthropocene and the serious possibility of self-caused extinction.

The bizarre thing about the anthropocene is that never has humanity been more powerful and never have individual humans felt so powerless. This is because so much that drives the circumstances of the anthropocene is the aggregation of apparently negligible acts, often amplified by technology, rather than decisive acts by autonomous decision-makers.

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

Most of what we think of as distinctively human has occurred in the last 10,000 years in the Holocene - a period in which the Earth was abnormally quiet.

There'll come a time when airplanes are much more efficient when it comes to producing lower levels of greenhouse gas emissions, there'll come a time when we'll be able to offset those emissions much more effectively than we do now. But alas at the moment, flying airplanes is really one of the least defensible things that we do and it's one of the things that I indulge in quite frequently, alas.
