quote: Don’t be so positive Fully 101 of the 116 models the Intergovernmental Panel on Climate Change uses to chart what lies ahead, ASSUME that CARBON will be TAKEN OUT OF THE AIR in order for the world to have a good chance of meeting the 2°C target. The total amount of CO2 to be soaked up by 2100 could be a staggering 810bn tonnes, as much as the world’s economy produces in 20 years at today’s rate (see article(1)). Putting in place carbon-removal schemes of this magnitude would be an epic endeavour even if tried-and-tested techniques existed.

It is important, that people know, that this assumption has been made. It also means that the climate goals are unreachable and that we are basically being lied to.
