We live at a time when emotions and feelings count more than truth, and there is a vast ignorance of science

I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while.

I think that we reject the evidence that our world is changing because we are still, as that wonderfully wise biologist E. O. Wilson reminded us, tribal carnivores. We are programmed by our inheritance to see other living things as mainly something to eat, and we care more about our national tribe than anything else. We will even give our lives for it and are quite ready to kill other humans in the cruellest of ways for the good of our tribe. We still find alien the concept that we and the rest of life, from bacteria to whales, are parts of the much larger and diverse entity, the living Earth.

It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that, but it's got all the sort of terms that religions use. The greens use guilt. That just shows how religious greens are. You can't win people round by saying they are guilty for putting (carbon dioxide) in the air.

Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

The inertia of humans is so huge that you can't really do anything meaningful.

By the end of this century, climate change will reduce the human population to a few breeding pairs surviving near the Arctic.
