None of these environmentalist wackos ever mention the Medieval Warming Period, circa 1400’s, when the Earth was six degrees warmer than today and the Arctic Ice cap melted.
Without the intervention of humans, and without a single oil well or internal combustion engine in the world, the Arctic eventually became colder once again and the ice cap returned.

I’m wondering about Greenland and the Vikings. If it was warmer, and the glaciers were melting, Greenland would turn pretty damn green from all the meltwater runoff during that period.
