Houston we have problem

I don't know about that. As people are starting to develop farming ... in Greenland ... I find myself unable to dismiss the idea of global warming. Forget the yearly temperature measurements, forget the current fluctuations and just take a look at Greenland.
In the 80s it was an icebox through and through. Nowadays you have this, at least in the south of it http://www.spiegel.de/international/...434356,00.html

That's the thing...
Farming on Greenland happened during the Viking age, but was discontinued due to global freezing in the late 13th century. Normalization would be a better term for Global warming.
