According to straightdope.com:
In a 27 News interview at his Oshkosh plastics factory, Johnson said the rise in Earth's temperature was more likely caused by solar activity than man-made carbon dioxide emissions, and that shifting climate patterns were part of an ongoing natural cycle.
"There's a reason Greenland was called Greenland," he said. "It was actually green at one point in time. And it's been, since, it's a whole lot whiter now."
Did anyone vet this guy? Johnson is still polling well against Sen. Russ Feingold. This is all even more amazing since he's made a number of major verbal gaffes, ignored or forgotten by the major media outlets throughout the state, where he continues to restate those same retracted gaffes again and again.
Erik the Red was forced to leave Norway because (he was) involved in killings (details are not given). He used the time to explore the rumored lands to the west.
He purposely chose the pleasant name Grænland ("green land") to attract settlers, but the choice wasn't exactly misleading. Some parts of Greenland, especially the parts the Norse settled, really are green.
