Since CO2 is soluble in water and the oceans cover a majority of the Earth's surface, the oceans sequester more CO2 than any other CO2 sink.
Because of the inverse solubility of CO2 with temperature, the colder the oceans get, the more CO2 they can absorb.
Conversely, when the oceans get warmer, they expel CO2.
Atmospheric CO2 therefore follows global temperatures, it does not cause them.
You can see the yearly global atmospheric CO2 fluctuation as the oceans warm and cool with the seasons in the NOAA graph below.
The "settled science" that CO2 causes "climate change" is criminal sophistry.
Besides that, CO2 is plant food, without it we DIE.
It’s more than just solubility that makes the ocean such a great carbon sink. Phytoplankton is eaten and becomes incorporated in all those carbonaceous shells that eventually end up like the chalk cliffs of Dover. It’s that huge buffering effect of the ocean that allows life on Earth as we know it.
