Even more to the point CO2 is a very weak greenhouse gas. All the models require that CO2 merely act as a trigger to up H20 levels which is what actually causes the real temperature change. You can double atmospheric CO2 and get only a 1 C increase in temperature.
But again, as more water vapor gets into the air, there are more clouds, whose tops reflect sunlight away from the planet! So it’s by no means a simplistic issue. Science as we know it has too little data to make anything but SWAGs (slyentific wild arse guesses).
More to the point, any greenhouse effect from CO2 would mainly act to produce milder weather in winter, which seems like a good thing.
Increased water vapor is self-limiting, since more evaporation results in more rain, and more clouds that reflect sunlight back into space.
Thanks! That is exactly the Cause and Effect that is required to Scientifically Test the Global Warming speculation.
Since there are only a handful of documented cases where CO2 exceeded 400 ppM, (roughly every 100 kyr), the data that you present is consistent with the idea that CO2 concentration in the atmosphere has little effect on air temperature, or ever has.
What an inconvenient truth!
