“The concentration of carbon dioxide in the atmosphere is so high that it is causing significant damage and it will remain high for thousands of years.”

Let’s not exaggerate with hyperbole. The Earth’s CO2 “concentration” is 400 parts per million, which is 0.04%. For those who are math challenged, that’s 1/25th of 1%. Said another way, if you had a gallon of water, 0.04% of that would be less than 6/100ths of a fluid ounce or 30 drops.

Anyone who thinks that miniscule amount of CO2 is the big driver of climate has been seriously hoodwinked. Don’t believe me, just read what others have said:
“The (climate) models are convenient fictions that provide something very useful.” (e.g. Propaganda)

it only matters what people believe is true.“ (Are you getting the truth?)
