Rocks oxidise. The most abundant element in the earth's crust is oxygen. Any thought that rocks would absorb more CO2 is fanciful. CO2 is a heavy than air gas and therefore inhabits lower levels, gorges, valleys and such.

It has been called marsh gas because of the latter and the generation of some CO2 via vegetation rotting/composting.

Water also absorbs much and as a consequence our oceans are becoming increasingly acidic, carbonic acid.

CO2 prevents infrared from reflecting back into space and therefore retains some heat. As we pump more and more into our atmosphere, this increases both above effects.

And as CO2 is a super plant fertiliser, Plant growth becomes lusher and more verdant.

This increased plant growth is accompanied by increased plant moisture aspiration. And as a result, more heat retaining, thermal blanket humidity. The greenhouse effect.

The solution is to not put more CO2 into the system than it can absorb. And that means we must replace fossil fuels with something that is carbon free and as of now, massively cheaper, i.e., nuclear power as MSR thorium.

Which comes with PKWH prices as low or lower than 3 cents. And with this a huge economic boost and growth. Job and investment opportunities that will have to be seen to be believed! I kid you not.

All that prevents the foregoing are intransigent recalcitrant and or owned politicians.

Hi Alan,

It might surprise you that most of the Earth's atmospheric CO2 has been sequestered as carbonate minerals as a result of the weathering of volcanic rock. It is water based chemistry and yes it does absorb a lot of CO2.

And AlanB the oceans will never become acidic and water vapour is much more effective as a so-called greenhouse gas than CO2 will ever be:
"Re The term "ocean acidification" -
The ocean is not acidic, and model projections say the oceans won't ever become acidic. So why call it ocean acidification?
Ocean acidification refers to the process of lowering the oceans’ pH (that is, increasing the concentration of hydrogen ions) by dissolving additional carbon dioxide in seawater from the atmosphere. The word “acidification” refers to lowering pH from any starting point to any end point on the pH scale...

From NASA: Because warmer air holds more moisture, its concentration of water vapor increases. Specifically, this happens because water vapor does not condense and precipitate out of the atmosphere as easily at higher temperatures. The water vapor then absorbs heat radiated from Earth and prevents it from escaping out to space. This further warms the atmosphere, resulting in even more water vapor in the atmosphere. This is what scientists call a "positive feedback loop." Scientists estimate this effect more than doubles the warming that would happen due to increasing carbon dioxide alone...

Water vapour can also form clouds which reflect heat. It has been speculated that before the runaway greenhouse effect on Venus a substantial amount of heat was reflected from the Sun facing side by water vapour clouds. Its lack of a magnetic field to deflect charged particles caused the ionisation of water molecules, eventually causing the total loss of water from the surface and atmosphere. Without water, CO2 could not be sequestered as carbonates nor were there water vapour clouds to reflect heat, and those carbonates which had formed broke down with the rise in temperature, releasing CO2 back into the atmosphere, eventually resulting in what is observed currently.

I hope that the increase in temperature will be self regulating, both from an increase in cloud and from increased rainfall causing more rock weathering. There might be a prospect of sequestering more CO2 with geoengineering, but I doubt that the shouty people would let that happen given how unhinged they get at the mention of nuclear power.

Fester, Let's not forget what Nobel Prize winning scientist Dr John Clauser said last year about clouds and how they were overlooked in computer models
"....Clouds play a paramount role in regulating the Earth's temperature, serving as a "cloud-sunlight-reflectivity thermostat" that "controls the climate, controls the temperature of the earth, and stabilizes it very powerfully and very dramatically," asserts Mr. Clauser.
