New climate change theory - did something dramatic happen 5200 years ago?

 Poster: A snowHead

The discovery of a bed of plants frozen under a Peruvian glacier is prompting a new theory about climate change: that a sudden and dramatic cooling occurred 5200 years ago.
"Something happened back at this time and it was monumental," says Prof Thompson of Ohio State, who presented evidence at this week's annual meeting of the American Geophysical Union. He suggests the climate shift 5,200 years ago was global.
However, a link is then drawn to the 'entrapment' of Oetzi, the man whose frozen body was found on an Austrian glacier.
This seems quite incorrect, since Oetzi was not (according to the most recent evidence I've seen) trapped by the ice, but was killed by an arrow!
Anyway, here is a report from FT.com.

Interesting. He should check his bible, wasn't the great flood about 5,000 years ago, give or take? Apparently the Med used to be a dried up lake bed below sea-level. The dam between Gibraltar and Africa broke and the lake flooded over a period of several months.

There is also a theory about the great lakes area flooding into the northern atlantic which stopped the North Atlantic conveyor causing freezing in Europe.

As I understand it, and I only have a vague understanding of these things, dramatic climate change caused by catastrophic/monumental events is not uncommon when viewed over a long enough time frame.

They can be set off by impacting bodies (comets and the like) or volcanic eruptions on a massive scale (I forget the correct term, but they make the Mount St Helens eruption look puny).

I'm sure that other snowHeads can provide better information.

Ultra-plinian. Named after Pliny the Younger, a Roman Senator who described the eruption of Vesuvius that destroyed Pompei.

Anyone interested in the Pliny link might enjoy Robert Harris's novel about and called Pompei... It's a great read.

davidof, and very recently there have been claims of the discovery man-made structures under the sea off Cyprus. The finders say this is evidence of the location of Atlantis. See this site for more info.
