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

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

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 know that to personalize the Earth System as Gaia, as I have often done and continue to do in this book, irritates the scientifically correct, but I am unrepentant because metaphors are more than ever needed for a widespread comprehension of the true nature of the Earth and an understanding of the lethal dangers that lie ahead.

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

Sadly, it's much easier to create a desert than a forest.

Nowadays if you're dependent on a grant - and 99% of them are - you can't make mistakes as you won't get another one if you do.
