Gee, how on earth did the world survive the MWP, when they grew grapes on Greenland?
I've yet to hear some kind of a coherent explanation from the warmists about the warming period in Greenland (and obviously a lot of other places) more than one thousand years ago. It's like they refuse to acknowledge the fact that a large area of the Earth had a tremendous warming period for about 400 years without internal combustion engines or many humans for that matter burning whatever and adding too much carbon to the atmosphere. It went down the memory hole...something leftists have a habit of doing with things that contradict their agenda.
