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

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.

Obama's clean power plan, methane regulations, and increased fuel economy standards are about as good as our political system can do at this point in our history. Let's embrace these things, make them work, and push for more, rather than denouncing them because they're 9th best (which they are).

If we're interested in the continuation of the human experiment we need to focus on resilience and coping with change (whether natural or anthropogenic) rather than living as if God or nature has given us a nice, orderly, calm, Babbit-like existence.

We're not good at noticing slow, steady changes in our environments, our senses are not very acute compared to those of many animals, and we're pretty awful at abstract thought, much less acting on it.

When it comes to climate change it's all the usual barriers: greed, mendacity, ignorance, short-sightedness and so on, manifest in the extreme power of corporations, the weakness of government, and the indifference of citizens.

On my reading of history people who want to bring us the best are usually the people we ought to be afraid of.
