I notice that warmist/alarmists kooks ignore the well-known LOG function of C02 and the very small CO2 forcing increase of a doubling from 280 to 560 ppm like this:
"Next, here is the radical change in downwelling radiation at the surface from the increase in CO2 that is supposed to be driving the “CLIMATE EMERGENCY!!!” What I’ve shown is the change that in theory would have occurred from the changes in CO2 from 1750 to the present, and the change that in theory will occur in the future when CO2 increases from its present value to twice the 1750 value. This is using the generally accepted (although not rigorously derived) claim that the downwelling radiation change from a doubling of CO2 is 3.5 watts per square metre (W/m2). The purpose is to show how small these CO2-caused changes are compared to total downwelling radiation.
The changes in downwelling radiation from the increase in CO2 are trivially small, lost in the noise …

This is WHY I know the AGW doom believers are stupid as hell on this because the postulated increase is so freaking small!!!
