The conceptualizer of Project Orion, man's only hope to reach
interstellar space also knows something about global warming. But it
won't endear him to the hysterical nuts who think the World is about to
end.

Science can fix climate woes, author contends

Freeman Dyson tells students a wet Sahara once supported livestock
herds

After branding himself a heretic, mathematician and physicist Freeman
Dyson told a Fairhaven College audience that fears of global warming
are overblown.

Dyson acknowledged that human activity is adding carbon dioxide to the
Earth?s atmosphere, and that could raise its temperature. But he said
he finds scientists? climate models unconvincing.

He also expressed confidence that the negative effects of global
warming,
if any, could be overcome, while some areas of the Earth would likely
benefit from the change.

Six thousand years ago, Dyson said, glaciers in the Alps were much
smaller than they are today, and the Sahara was wet enough to support
herds of livestock.
