There’s that damn word....average...Now, we all know how you get an “average”, right?? You keep some numbers that look good, throw out some that look bad, keep some because you think they’re more truerer, throw some out because they mess up the answer....THEN....you toss all the numbers in a fish bowl....and pick the one up your sleeve.
Excellent explanation, slightly tongue in cheek, but certainly true for the IPCC climate change "scientists."
