http://www.commondreams.org/headlines06/0905-06.htm The rapid rise in greenhouse gases over the past century is unprecedented in at least 800,000 years, according to a study of the oldest Antarctic ice core which highlights the reality of climate change.
Air bubbles trapped in ice for hundreds of thousands of years have revealed that humans are changing the composition of the atmosphere in a manner that has no known natural parallel.

"Ice cores reveal the Earth's natural climate rhythm over the last 800,000 years. When carbon dioxide changed there was always an accompanying climate change," Dr Wolff said. "Over the past 200 years, human activity has increased carbon dioxide to well outside the natural range and we have no analogue for what will happen next.

"The rate of change is probably the most scary thing because it means that the Earth systems can't cope with it," Dr Wolff told the British Association meeting at the University of East Anglia in Norwich.
"On such a crowded planet, we have little capacity to adapt to changes that are much faster than anything in human experience."

"we have no analogue for what will happen next"
whatever happens, it won't be good.
we could stop driving cars that is making it worse. but no one will do that. however, there will come a time, soon, when global warming will force us to.
I wouldn't want to get pregnant now.
