Being a Keynesian, budget deficits were my biggest government policy concern for about 25 years. After all if the US had stretched its credit too far then during a fiscal crisis it couldn’t borrow what was needed for enough fiscal stimulus.
Then I began to read about and understand climate change issues. I harkened back to a time I was watching the Today Show while getting ready for school and one of the hosts had a globe on their desk. They said the ink on the globe was as thick as a something like over half the atmosphere. I remember how shocked I was that such a thin layer of air made such a difference to a planet. (I recalculated this. There would have to be quite a few layers of ink to be that thick, the thickness of a human hair is much closer to the size.1) With something so thin we had to be very very careful.
CO2’s greenhouse effects can be measured in a laboratory. The only question is how much of it is piling up in the atmosphere when mile long coal trains were rolling by my old house three times an hour, and I’m stopped in miles of cars all burning their gasoline.
The chart above is showing not all of the CO2 is being absorbed as new records are being established.
