Now if only he could post one that backs up his claim, I can stop mocking his idiocy.
timelines overlap. he's done.
450000 to 800000 years ago, Greenland green --link presented
16000 years ago NE recovered from an over million year ice age--link presented. If you can't see the overlap timeline, I can't help you.
16000 years ago NE recovered from an over million year ice age--link presented
Yes, his theory that North America was buried under ice, continuously for a million plus years, until 16000 years ago, was funny.
And wrong.
So if his "overlap" is based on bad info, why do you feel that proves his claim?

The oldest ever recovered DNA samples have been collected from under more than a mile of Greenland ice, and their analysis suggests the island was much warmer during the last Ice Age than previously thought.
The DNA is proof that sometime between 450,000 and 800,000 years ago, much of Greenland was especially green and covered in a boreal forest that was home to alder, spruce and pine trees, as well as insects such as butterflies and beetles.
From the genetic material of these organisms, the researchers infer that Greenland’s temperature once varied from 50 degrees Fahrenheit in summer to 1.4 degrees Fahrenheit in winter—the temperature range that the tree species prefer.
“We have shown for the first time that southern Greenland … was once very different to the Greenland we see today,” said study leader Eske Willerslev of the University of Copenhagen.
Less glacial cover in ancient Greenland means the global ocean was probably between three and six feet higher during that time compared to current levels, the scientists say.
“To get this site ice free you would’ve had to remove the ice cover from about the southern third of Greenland,” study team member Martin Sharp, a glaciologist at the University of Alberta, Canada, told LiveScience.
The findings, detailed in the July 6 issue of the journal Science, demonstrate how far the young field of ancient DNA research has come: scientists can now recreate an environment’s climate and ecology using only recovered DNA, without the need for fossils that might be absent or hard to reach.
“To go from dirty water to a forest full of insects is pretty amazing,” study team member Matthew Collins, a biomolecular archaeologist at the University of York, said in a related Science news article.
Greenland’s thick ice sheets served as a perfect, natural freezer for preserving the prehistoric DNA. Older genetic samples have been found, but none in such pristine condition as the new Greenland samples.
The team says their technique could be applied to DNA found in other icy parts of the globe, such as Antarctica. “Given that 10 percent of the Earth’s terrestrial surface is covered by thick ice sheets, it could open up a world of new discoveries,” said study team member Enrico Cappellini of the University of York in the United Kingdom.
Plants still survive in Greenland today, although mostly along the island’s coast, since the interior is blanketed in ice. “There’s tundra vegetation,” Sharp said. “There’s also dwarf birch probably, and willows almost are certain. But not pine or spruce, which we have in the DNA here.”
I never denied Greenland was green, BTW.
No mention in there of continent spanning glacier in NA during any green period in Greenland.
Thanks for trying to help LaDerpster, he can use all the help he can get.
you're correct, in that link there was no mention of north america. I agree. It was the post with the link for North America in #220. Again, timelines intersect between 450,000 and 800,000. so if the link in #220 says north america was ice up to 16,000 years ago out 1 million years, and greenland was green less than that time frame at 450,000 to 800,000, they intersect right there. 16,000 years ago is years away from 450,000 year ago in my math.
