The reaction to the polar vortex reminds us it is important to have a citizenry who can distinguish between scientific fact and fiction…
On this, and most other things he comments upon, Dr. Michael E. Mann is absolutely, and wholly correct.
I can add something personal about the cold winters in Chicago in the 1970’s, the frozen Lake Michigan that we walked on one kilometre out. I was given a pair of Sea Otter fur mittens by my fellow Operating Engineer in Local 302a, who I dug trench-line with through permafrost soil. One yard a 10 hour day, down only 8″. I had so many blisters!
Digging permafrost is not what you do for pleasure. It was what I did to pay for my education at Northwestern University in the 1970’s. I worked alongside Inuit and Tlingit. Texan, and Canadian. That summer, I fortunately worked with an Inuit from Little Diomede, who had his wife make me a pair of Sea Otter mittens. “It gets real cold in Chicago, I hear. So my wife made a pair for you to take back to school. Come back with all the fingers. I’ll need help on that pick!” We both laughed.
