Karoly summarizes as follows:
“Science has established that it is virtually certain that increases of atmospheric CO2 due to burning of fossil fuels will cause climate change that will have substantial adverse impacts on humanity and on natural systems. Therefore, immediate stringent measures to suppress the burning of fossil fuels are both justified and necessary.”
Happer’s key point is:
“Climate models don’t work. They have predicted several times more warming from greenhouse gas increases than has been observed.”
