Extreme climate change 55mya - Skywise - 09-15-2015
What I thought was a great BBC article on the "Palaeocene-Eocene Thermal Maximum" (PETM) event which occurred 55 million years ago. In that event, a global warming event happened which had all the effects scientists are warning of today, only back then it happened very quickly and more extremely.

Hi Brian, I read the whole article at the link you provided and most researchers seem to think the extremely fast warming then was slower than it is now...by several times. The warming in 13 years they start with is highly unlikely.
The article is interesting all the way through.

Yes, the article starts out with the 13 year thing, then goes into the controversy over it. Like the article said, the biggest problem is heating the oceans that quick. I have a little knowledge of the thermal properties of water and I agree; it would take a LOT of energy to heat the oceans that quickly. Possible, but need more evidence to support that conclusion.
Agreed that it was a very interesting article. And study of the PETM certainly has relevance to today's issues.
