A 10-10-2019 global warming letter stated: “The greenhouse gases trap heat in the atmosphere that otherwise would radiate into space.”

True; and water vapor (a greenhouse gas), traps about 1375 times more heat than man’s CO2; and about 8620 more heat than man-made methane.

The thing about WV is it’s variability from day to day and place to place over the earth; and that’s a big problem for climatologists when trying to get climate models to work. Consider that even a somewhat small up or down change in the massive quantity of WV may release or absorb far more heat, and therefore have more effect on temperature, than would a doubling of our current tiny CO2 level.

Oceans have a huge effect on WV level depending on amount of cloud cover blocking the sun’s energy, and, what the 40,000 mile “tank heater” (under-sea volcanic mountain chain) happens to be belching out at any given time.

So bring on the CO2, green plants love it and grow bigger as the concentration goes up, thereby creating a “greener planet.”

Like evolution, heliocentricity, and billions of years old earth, the “man-made global warming” position appears to be indefensible.
