For CO2 to rise by 100ppm it took
12,800 years in the #Eemian and 13,400 years in the #Holocene
from the low-point to the peak of the interglacial. The fossil civilisation raised CO2 by 140ppm within 170 years.
And I reckon, when the fossil civilisation breaks apart, natural rewilding is going to draw down > 100ppm into trees within 60 years. Research in a new #RCPcollapse can find out how much and what that stressful phase does to the weather, sea level rise and so on.
Nothing but a blip in the geological record: #Anthropocene
