Joe, is that 1C from doubling of CO2 due to associated temperature from GHG or associated temperature from GHG plus feedbacks?You seem to keep missing the point that associated temperature due to GHG does not care about how fast CO2 rises.You said that already. Did you know that atmospheric CO2 used to be ten times what it is today. Guess what? No one died.
12,000 years ago New York was under a quarter mile sheet of ice.
You keep missing the point... the CO2 level isn't just high, it's skyrocketing faster than the planet can cope with.
Those past increases did not happen over decades, they happened over millennia. In short, there was time for life to evolve to cope with changed climate.
Is it your belief that CO2 emissions will continue to rise exponentially? Because even the IPCC base projection does not show that.
Just how high do you think atmospheric CO2 will rise to by the year 2100?
At roughly 1C warming per doubling, CO2 is not going to produce any sort of tipping point. Hopefully for our descendants it will delay the next glacial period for a bit longer.
