How I learned to stop smoking and love Global Warming

How I learned to stop smoking and love Global Warming. Christmas Guest pudding from archaeologist Michael A. Lewis, Ph.D. Unlike most denialists, he believes in tree ring data. Good luck defending that in the comments! He also knows that modest Arctic warming a thousand years ago is proof of natural global warming in the same time period. Somehow. Funny, the Yamal tree-ring proxy chart he includes doesn’t particularly show that.

Lewis falls into the trap of seeing the forest and not the trees. He sees nothing worrying over the long timescales he’s used to thinking in, so why worry?

Two problems. First, the current rate of change is completely unprecedented, so his incurious lack of concern is ill-advised. Second, his own work on changing Arctic populations shows that climate change, whether natural or not, can have massively disruptive impacts. The existing Dorset Inuit disappeared and were completely replaced by the Thule Inuit. It must have sucked to be Dorset.
