Talk about clutching at straws. Its just fact that even if we stopped all CO2 emmisions now, global warming would continue. We've passed the point of no return now, that the permafrost is melting in Siberia releasing huge pockets of methane (which is 20x more effective at heating up the planet than CO2).
Face facts, we're ****ed.
As a planet we can't even do the most basic things like group up and force the Brazillians to cease cutting the rain forest... but with an idiot texan on one side and a nation of mass executioners on the other that should be no suprise!
Atmosphereic C02 levels are at around 380ppm atm with 450 being critical (I use that word with great under exageration) and 500+ being cataclsymic. Levels go up by about 3ppm each year. You do the maths.
