If I put myself on the side of those who see the world as warming up in a bad way, who see the general march of industrial culture as something undesirable, the one thing I must be beware of doing and which my colleagues on that side don't beware of doing, we must beware of saying we've got to stop changing the environment. There is no 'the' environment which we can change, the world is changing all the time.

We do have tendency, now in biology especially to make up stories, to make theoretical biology a kind of game, in fact we have game theory in biology which is meant to use the theory of games to make predictions or explain things.

To appeal to an omnipotent deity is to allow that at any moment the regularities of nature may be ruptured, that miracles may happen.

In fact perhaps the only law in biology is that all flesh is mortal and all species become extinct eventually.

People who have various kinds of politics for whom it is congenial for their apriority politics to say yes, things are getting much worse. They are opposed by people who also have a priori politics saying that this is the best of all possible worlds, capitalism is the greatest thing since sliced bread and you're just alarmists and so on and they can massage the data so it fits them.

My general impression about people like Steve Gould and Carl Sagan and so on is that when they disappear as individuals and are no longer appearing on the stage and they are no longer writing, that their lifetime of acknowledgement by the general reading public is not very long... There were many people in the 19th century who were equally famous people who gave working man's lectures, supporters of Darwin, we as scholars know their names but the general public never heard of them.

As an American I must say I haven't been very encouraged by the way in which the people who run the government in the United States have been listening to those contrary voices. And so long as the power to run the world lies in the hands of people who are quite happy to see it get warmer, or fuel be used more, then would those people who oppose it are crying in the wilderness - that's the real problem.
