Reply to "Ice Breaker Gets Stuck Trying to Rescue Global Warming Scientists Trapped in Antarctic Ice"

EDMONTON —Not in at least 450,000 years has Greenland been sufficiently ice-free to support a thriving forest, says new research by an international team of scientists.

The team looked at the bottoms of ice core samples from the two-kilometre thick ice sheets on Greenland. Researchers then analyzed the DNA found in these silty sections of the cores to see if they could identify and plants and animals from that era.

The DNA they found showed that southern Greenland had a boreal forest on it some time between 450,000 to 800,000 years before present, said University of Alberta glaciologist Martin Sharp, who participated in the research.

“The dominant tree species were things like spruce and pine, some members of the yew family and also things like alder,” he said. “Most of those, with the exception of yew, you could find in Whitemud Creek today.”

In fact, the yew is a tree species that won’t tolerate temperatures below minus -17 C, so this was a forest with a warmer climate than found in modern-day Edmonton.

I guess the old troglodytes exhaled a lot and fed their pet mastodons beans.

 

A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. The study also found that during the last warm period, about 125,000 years ago, the sea level was around 5 metres higher than today.
