The Next Ice Age
"While
most people still worry about global warming, I am more concerned about
the next Ice Age. A glaciation would present a serious problem for
survival of our present civilization, akin to a nuclear winter that many worried about 30 years ago.
Nuclear winter is all fantasy, of course; but ice ages are for real.
Natural
warming of the Earth reached a peak 65 million years ago. The climate
has been generally cooling ever since. Antarctic ice sheets started
growing 25 million years ago. In the last 2.5 million years, the Earth
entered the period of Ice Ages [the geological name is The Pleistocene]
and has been experiencing periodic glaciations where much of the land
was covered by miles-thick ice sheets."
