Very good. I had already seen Pielke's op-ed. The other two were also good.
Being a non-scientist, I still have to resort to framing the issue in terms I can comprehend. Somewhere around 900 A.D. the Vikings settled on Greenland. They didn't name it "Green"land because it was, like, white. For almost 500 years, they had an agrarian (i.e. "farming") society on ... Greenland. Around 1450 A.D. they abandoned Greenland because ... it got too cold.
So, when it gets too hot to farm on Greenland, then I'll talk to you about global warming climate change.
