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.

None of us are rational economic men as we're supposed to be portrayed in economic theory where mixes of passions, of desires, of moral principles, of self-deception, of altruism, of concern of others, of concerns for ourselves and an interest in our bank accounts. And social policies have to be responsive to the complexity of who we are as people or else, like the war on drugs, they're simply going to fail.

We're good at noticing sudden movements of middle size objects in our immediate visual field, but what is out of sight is for us is largely out of mind.

People with long memories and a vivid sense of the past have an immediate understanding of politicians like Donald Trump. They are not surprised by the behavior of Google, a corporation that notionally (until recently anyway) espoused the slogan "don't be evil" and then runs over individual people and even entire nations in the pursuit of profit.

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.

Is it in the interests of Britain to leave or remain in the EU? As we saw in the referendum, there are different Britains and they see their interests in different ways. For a lot of everyday blokes the EU affected their sense of identity in ways they disliked, and they were right in thinking that the EU didn't return much to them by way of economic benefits.

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).
