I was thinking something similar a couple of days ago.
The "anthropomorphic global warming" people have to explain every other period of unusually warm weather in history, going back tens of thousands of years... explain how it was not caused by SUVs and electricity generating plants.
Or at least they would have to explain these phenomena, if we had anything like a fair debate on the subject.
The Vikings were able to colonize Greenland during the Medieval Warming Period. Greenland is still colder today than it was 1,000 years ago.So what's the big deal? We will be able to live on Greenland again. And it helps the Russians because they will be able to make a better use out of Siberia.
