On Thursday, new EPA Administrator Scott Pruitt appeared on CNBC's "Squawk Box," and made a statement that has gotten a lot of attention. The statement was: "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."
I would have said that that statement was just a rather obvious truism. I mean, we have an enormously complex climate system, affected by literally dozens of factors, many of them hugely larger than us puny little humans -- things like the sun, solar wind, oceans, clouds, volcanoes, aerosols, multiple atmospheric "greenhouse gases" of which water vapor is the dominant one, tilt of the earth's axis, position of the solar system in the galaxy, and plenty of other things that we don't even know about. And in the era of reasonably good measurements, world average temperatures (a poorly defined concept to begin with) have varied within a range of around one to two degrees, with the accuracy of measurement not much less than the amplitude of the variation. With all that going on, does somebody claim to have the method to know precisely how much of the variation in temperatures derives from human activities? To what level of accuracy? Tenths -- or hundredths -- of one degree? Really? Where's the proof? The whole concept is inherently implausible. I don't even understand how Pruitt's statement is remotely controversial.
Well, needless to say, Pruitt's statement has caused a total freakout in the progressive press and media.

“Yep. Nothing but good seems to come from CO2 increases. Which is why a lot of future farming will happen in cities due to the high CO2 content of the air combined with cheap LED lights.”
I used to run a greenhouse and had Co2 emitters, ran them all day, crops loved it. Wouldn’t have been profitable without them.
Cars, trucks, jets are all mini-Co2 emitters collectively fertilizing our global crops.
