I remember reading some years ago that remnants of farm stuff like fences and barns were found in Greenland, under ice, or it melted. Sorry for being vague. But why would Vikings have settled there if it was too cold to farm at all?
Aha, did a quick search. Watts Up With That is the best debunker of global warming/etc that I know of. Here’s an article from this February, the writer of the article (not charles the moderator) at the end reveals his belief in “climate change” bs but the study must be sound or WUWT wouldn’t post it.

Study shows that Vikings enjoyed a warmer Greenland

Study shows that Vikings enjoyed a warmer Greenland
Chemistry of bugs trapped in ancient lake sediment shows a warm climate at a key time in Greenland’s history
Northwestern University
EVANSTON, Ill. — A new study may resolve an old debate about how tough the Vikings actually were.
Although TV and movies paint Vikings as robust souls, braving subzero temperatures in fur pelts and iron helmets, new evidence indicates they might have been basking in 50-degree summer weather when they settled in Greenland.
After reconstructing southern Greenland’s climate record over the past 3,000 years, a Northwestern University team found that it was relatively warm when the Norse lived there between 985 and 1450 C.E., compared to the previous and following centuries.
“People have speculated that the Norse settled in Greenland during an unusually, fortuitously warm period, but there weren’t any detailed local temperature reconstructions that fully confirmed that. And some recent work suggested that the opposite was true,” said Northwestern’s Yarrow Axford, the study’s senior author. “So this has been a bit of a climate mystery.”
Now that climate mystery finally has been solved.
The study will publish on Feb. 6 in the journal Geology. Axford is an associate professor of Earth and planetary sciences in Northwestern’s Weinberg College of Arts and Sciences. The study is a part of Northwestern Ph.D. candidate G. Everett Lasher’s dissertation research, based in Axford’s lab.
To reconstruct past climate, the researchers studied lake sediment cores collected near Norse settlements outside of Narsaq in southern Greenland. Because lake sediment forms by an incremental buildup of annual layers of mud, these cores contain archives of the past. By looking through the layers, researchers can pinpoint climate clues from eons ago.

They stayed there because they could farm but it was far from a 'Greenland'. If it was so toasty, why did they move south?
