New plan to remove trillion tons of carbon dioxide from the atmosphere: Bury it

beta.washingtonpost.com

Some parts of antarctica get very close the freezing point of CO2 in the winter. It might not take too much energy (wind?) to encourage the atmospheric CO2 to freeze and then bury that deep in the ice sheet where the pressure would keep it solid.

And WHERE do you PUT a trillion tons of stuff? It doesn't just 'magically disappear'.

Pie in the Sky thinking.

As the article explains, it’s sequestered in soil through practices like no-till.

A trillion tons of anything has a LOT of volume. Even assuming that we could somehow convert/compress a trillion tons of CO2 to 10 times the density of water (that is denser than solid iron would be) it would still take up 100,000,000,000 cubic metres = 100 cubic kilometres = 24 cubic miles = quite a sizable mountain

Trees are not as effective as grasslands for carbon sequestration.

Regardless, Ag can never be part of a carbon negative initiative. I am curious as to how this will go..
