Look at what is happening to Greenland... Why have the last 6 or 7 summers been the hottest ever on record? ok.. let's look at Greenland.
Do you know why it's called Greenland? Because it used to be green. The Vikings had colonies there when it was fertile farmland.
Yes, farmland.
This was during the Medieval Warm period, something that is (in)conveniently left out of my idiot cousin's little mockumentary (I can't call it a documentary because it's full of sh!t)
Even Ric Romero knows you can't farm on Greenland now because it's too cold.
