>The Earth takes in about 240 watts per square meter of energy from the sun. At the beginning of the study period, in 2005, it was radiating back out about 239.5 of those watts — creating a positive imbalance of about half a watt. By the end, in 2019, that gap had nearly doubled to about 1 full watt per square meter.
is some of that possibly due to the large number of solar power plants absorbing sun's energy and generating electricity?
Obviously, this "unprecedented" situation is supposed to be due to human CO2 emissions. But if so, wasn't the situation more dire back when CO2 ppm was 800, rather than 400? Wasn't it worse back when CO2 ppm was 1600? Or when it was 4000, 10x current levels?
It seems odd that our current situation would be unprecedented given that the atmosphere had much higher CO2 levels than it does today for almost all of earth's history.
