We'd never have got a chance to go outside and look at the earth if it hadn't been for space exploration and NASA.

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

The oil companies regard nuclear power as their rival, who will reduce their profits, so they put out a lot of disinformation about nuclear power.

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.

Life does more than adapt to the Earth. It changes the Earth to its own purposes.

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.

Climatologists are all agreed that we'd be lucky to see the end of this century without the world being a totally different place, and being 8 or 9 degrees hotter on average.
