Kewp was simply trying to refute my point about CO2 not being a greenhouse gas (in the sense of being heat blanket) and intimidate me with Wow sarcasm.
Other problems with CO2 explanation: 1/2 of the warming in the last century occurred before the 1940’s, yet most of the CO2 emissions occurred after the 1940’s. So there’s a lack of correlation here: if CO2 is the cause, then what happened prior to 1940?.
Other sources also tell me that temperature change grows logarithmically w.r.t. CO2 increase, meaning that the more CO2 we put out, the less of a difference it makes.
