Ed Berry is a physicist who earned his PhD back in the Mesozoic era. From Caltech, no less. He now lives in Montana as a mountain man, battling long-horned sheep for food, coming into town once a year for saltpeter and a ballot.
Ed is a hard core climate denier. (And, naturally, a hard core Trump supporter.) So hard core he doesn't care when he makes basic, boneheaded mistakes -- because, you know, one never admit error when a bear is charging at you, or someone who understands the science.
Q: How much has atmospheric CO2 increased since the pre-industrial era?
A: That's an easy calculation, right?
That's simple, clearly.... But not in Ed's denier-land. This is from Ed's blog:
30%?? Whoa.... That's just a dumb arithmetic error. It comes from calculating
change/final_amount = (408 ppm - 280 ppm)/408 ppm = 31%
which is obviously NOT how to calculate a percentage change. You and I learned this in 5th or 6th grade. So did Ed. It's a trivial, arithmetic error.
But one that mountain men will not admit to. Ed is so much of an uber denier that he can't even admit to a simple arithmetic error, can't say, Oops!, you're right, let me fix this and go on.
Now, what can you do when a denier won't accept arithmetic?? I have no idea.
It's all part of Ed's Big Misunderstanding -- he writes, "Why human CO2 does not change climate." He's so sure of this, of course, just as he's sure that the increase in atmospheric CO2 is 30%, even though every 6th grader knows better. He's submitted a paper somewhere (he won't say where), and is proud that after 4 months it hasn't yet been rejected. Remarkable!
Sorry, but I don't accept PhDs in physics misunderstanding the basic science behind global warming -- the Earth emits infrared radiation, and the atmospheric GHGs absorb it. Rejecting that is bad enough. But claiming that our HUGE emissions of CO2 aren't piling up in the atmosphere -- somewhere -- that's is just, I'm sorry, pure stupidity. Dumb. Ignorant. Idiotic.
But what can you do when deniers won't accept the basic rules of arithmetic? Where do you even start?? Beats me....
