Man's contribution to that number is .05%, the remainng 95& comes from nature.....
Man's contribution is such an insignificant number that it's not even worthy of discussion.
But yet the climate alarmists have successfully convinced the global idiots that CO2 levels created by man are destroying the planet.
The rise from 0.028% to 0.042% is almost entirely manmade. The CO2 production from nature is about 30 times more than manmade production. However the absorption of CO2 by nature is about equal to the production by nature. Mankind's CO2 absorption is essentially zero.
CO2 levels are definitely manmade this time around. But temperatures don't follow CO2, it's mostly the other way around.
