Antarctic historical melts? http://news.yahoo.com/s/ap/20090318/ap_on_sc/sci_antarctica_melt
Keep in mind that this article is by the AP Science Writer and doesn't show the whole study. If there is anyone that has access to the journal, Nature, could you expand on this?
One thing that caught my eye was this statement...
"Scientists said the core samples indicated the massive ice sheet on West Antarctica regularly melted about every 40,000 years during a period when the climate was about 5 degrees warmer than now and carbon dioxide levels were slightly higher. The past melts coincided with regular changes in Earth's tilt, something that isn't occurring now."
