Really?
I didn’t realize that. Thank-you.
I recently also read that CO2 only absorbs select frequencies of infrared radation. As you increase atmospheric concentrations of CO2, each increment traps less and less heat until it levels off logarithmically.
Another thing that the GW people are not answering (that I can find anywhere) is why temperatures have dropped since 1998 even as CO2 production has continued to increase. There are so many holes in their theory that their credibility drops by the day and yet politicians are setting policies that require all of us to reduce our quality of life based on this junk science.
“I recently also read that CO2 only absorbs select frequencies of infrared radation. As you increase atmospheric concentrations of CO2, each increment traps less and less heat until it levels off logarithmically.”
It’s worse (better) than that. CO2 absorbs only a few frequencies of IR radiation (i.e., radiated heat). The kicker is that the CO2 in the first 10 or so meters of air absorbs close to 100% of the heat radiated by the ground in those fequencies. So if you doubled the CO2 in the atmosphere, THE SAME AMOUNT OF HEAT WOULD BE TRAPPED, just a little closer to the ground. In fact, you could increase the CO2 in the atmosphere by 100 times, and THE SAME AMOUNT OF HEAT WOULD BE TRAPPED, just closer to the ground.
So is trapping the heat closer to the ground a problem? Nope — the atmosphere at ground level is active enough (even on a seemingly still air day) that convection, wind, etc. spread the heat out immediately.
Now, the AGW nuts either (1) don’t have enough science background to understand this or (2) create some hand-wavey theories to explain it away. Most (all?) of those theories blatantly violate the Second Law of Thermodynamics, but they are hand-wavey enough to fool the scientifically illiterate (i.e., politicians and most voters).
Since 1998 was so much hotter than usual, with the strong El Niño, comparisons to it are cherry-picking.
