March 10, 2017
By

I want to parse this statement by new EPA Chief Scott Pruitt, as quoted in this New York Times article: I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.

Butcher: which part of the leg do you want? Me: All of it, in five pieces please

When I arrived, my fitness tracker had given me credit for taking 9,124 steps and climbing 81 flights of stairs during those four hours, even though I only left my seat once during a short…
