Cave research suggests fast-forming and -melting glaciers http://apocadocs.com/s.pl?1266006708
Scientists studying the history of sea levels in Spain say they've found evidence that glaciers can form and melt faster than previously thought.
The research done in caves on the Spanish island of Majorca suggests that the sea level 81,000 years ago was more than a metre higher than it is today.... This finding that the sea level was higher 81,000 years ago than it is now suggests global temperatures were at least as high as they are now, if not higher, even though the level of carbon dioxide in the atmosphere was lower then.
The results, published this week in the journal Science, are at odds with conventional thinking on how fast ice sheets can form and recede.
If the results are verified, they could change the way geologists think about the way ice ages come and go.
