I’m not sure your argument holds up.
To me, the bigger question is: Our inability to properly model cloud formation and precipitation. Water Vapor plays a much bigger role in dampening climate changes. Unless we fully understand it, we can’t accurately project the result of increasing GH gases.
The ability of CO2 to absorb infrared radiation is not linear.
If a certain percentage of CO2 in the atmosphere absorbs 50% of the infrared at specific wavelengths, doubling that percentage would only increase the absorption to 75%. Three times, 87.5%, and four times, 93.75%.
Also, suppose a certain percentage absorbs 90%. Doubling it would absorb 99%, so only a 10% increase (9%/90%).
I’ve not looked at how much CO2 absorbs at 400 ppm, so these are just examples. But if the current absorption rate is high, adding more won’t significantly affect how much is absorbed.
Water vapor is about 10x more of a GHG than CO2, if it were science not politics we’d be worried about it. But it’s hard to declare water a polutant
“Our inability to properly model cloud formation and precipitation.”
The magnetic field of the sun controls the amount of cosmic rays reaching the Earth. Many scientists believe cosmic rays are part of cloud formation. When the sun is strong its magnetic field deflects more cosmic rays away. Weak sun, less heat, weak field, more rays, more clouds, even less heat. Strong sun, more heat, strong field, less rays, less clouds, even more heat.
The resulting water vapor cycles you mentioned are the only damper to the above.
If you have ever seen a “cosmic ray detector” at a jr. high science fair, this makes a lot of sense.
The Earth’s magnetic field protects us from the sun’s solar winds. I don’t know much about it BUT, it is common knowledge that the N pole is way out of place and moving in one direction.
The environment that allows us to live here is not a delicate balance. It is a remarkable combination of forces we cannot control. There are many environmental things we can screw up. I don’t think altering the climate is one of them.
Sounds as though you have bought in to their greenhouse gas BS and are convinced that we can do something about it.
