No, you asserted it with a question begging fallacy.
Lurkers, you be the judge, do you think that 120 years ago, Angstrom had the tools to measure the heating of the air in his experiment accurately enough to record the heat that amounts to 0.0001 deg.C/day? I don't believe that he imagined that the air in his experiment heating up mattered at all.
He measured the IR transmission, not the temperature. You obviously know nothing whatever about it.
Lurkers, do you think that Angstrom was careful to be sure that the air in his experiment was isolated so that the tiny amount of heating would not escape into the glass walls of his experimental apparatus? I don't.
Lurkers, I don't believe that Angstrom's experiment proved anything. He did not have tools that were accurate enough to pick up the change in temp that was about 0.0001 deg.C. I'm being generous and assuming that he ran his experiment for 24 hours. If, for example, he only ran it for 24/10 =2.4 yours then the heating is less, just 0.00001 deg.C.
TtP entire argument hinges on Angstrom's experimental results. If you can't believe that he could measure temps accurately enough to tell the difference between 0.0001 deg.C change and no change, then you don't believe that his results prove what he though it proved.
Let me be clear. In Angstrom's experiment, the CO2 inside his glass container was absorbing IR heat/light. The IR was re-emitted. But, some was really stopped inside his container. It was so tiny an amount that a mercury thermometer could not measure it accurately. He would have had to use a very hot heat source for his IR heat/light and run the experiment for days on end, while keeping the air inside it thermally isolated from that hot heat source. That is, if the heat source could heat the air in the container some other way than by the IR light/heat being shined through it, then the result was invalid.
No, he just measured the difference in the amount of IR radiation that made it through the tube.
Above, TtP admits that the effect was tiny. I assert that it was so tiny that it would have been immeasurable.
If it was immeasurable, how could it significantly heat the earth?
Note that, TtP has said that any student can repeat his experiment in a high school (IIRC, he said HS lab) science lab. Do HS science labs have thermometers accurate enough to measure temp changes of just 0.0001 deg.C?
I said an ordinary university physics lab, and I stand by that.
