CO2 is about 0.04% of the atmosphere. Humans are reaponsible for about 3% of that, or about 0.0012%. Of that the US is responsible for 2% or about 0.000024%.
Volcanos release far more CO2 than human activity. Maybe that's why they don't wanna talk about La Palma during their Carbon Crisis conferences.
It's another hoax using statistics and the tyranny of small numbers, just like the COVID plandemic.
