OK, The mass of the atmosphere is about 5*10^18 kg. Now, by volume, CO2 is about .04%, and CO2 is about 1.5 times as massive per volume as air (44g/mole vs. 29 g/mole), so that makes it about .06% by mass.
In other words, the total mass of CO2 in our atmosphere is about 3*10^15 kg.
Each year, we put about 40 billion tonnes of CO2 into the atmosphere, so about 4*10^13 kg.
If you divide those two numbers, you find that in 75 years, we put the equivalent of ALL the current CO2 into the atmosphere.
Now, our production of CO2 is higher than it was 100 years ago, but clearly a century of our emissions has a significant effect on total CO2 levels.
Right because it's a cycle, plants absorb CO2 more quickly the more there is in the atmosphere, making the planet a slightly greener place, but the increased uptake slightly lags the increased production...
....the end result of which, is a little over 1 extra molecule CO2 in 10,000 of air... this simply cannot trap a significant amount of heat. And if you disagree you'd need to take it up with even most climastrologers. Any significant effect on climate, relies 100% on hypothetical computer simulated feedback loops, involving not CO2, but water vapor mostly, which is what actually drives Earth's GH effect.
The Ordovician ice age had 1000% of the CO2 levels than we have today
But nobody cares to even get that far into the science, this is a political movement. It's about the 'solutions', and the utterly vast transfer of wealth and power these entail
the 'problem' can be anything, and can and does change with the weather
