There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

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

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

All the modelling we do shows that the climate is poised on the jump up to a new hot state. It is accelerating so fast that you could say that we are already in it.

We are in a fool's climate, accidentally kept cool by smoke, and before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.

Those of us who consider ourselves to be somehow involved in the birthing of a new age, should discover Gaia as well. The idea of Gaia may facilitate the task of converting destructive human activities to constructive and cooperative behavior. It is an idea which deeply startles us, and in the process, may help us as a species to make the necessary jump to planetary awareness.

Science always uses metaphor.
