Approximately how many GtC are accumulating in the atmosphere due to human activity each year?
The rest of the CO2 dissolves in the oceans, making them more acidic.
The plants convert carbon dioxide gas into solid carbon.
CO2 is a trace atmospheric gas that does not trap heat and is a non-factor in Climate Change. The idea of "trapping heat" violates the Laws of Thermodynamics is "junk made up science" that has no experimental scientific support.
