Neogeoengineer & PR hack Papaya Fancier Eric Worrall's latest brainstorm manages to make it through nearly four paragraphs before making its first three order of magnitude science error :

Lets Cook Limestone to RaiseAtmospheric CO2 to 1000ppmDumbarton castle in 1800 and functioning lime kiln with smoke in the foreground. |
The world has a CO2 problem – there is not enough free CO2 in the atmosphere, to maximise food production, alleviate world hunger, green deserts, and to attempt to hold off the next ice age. But if my calculation is correct, raising CO2 to a safer level would be surprisingly affordable.
Although a lot of nonsense has been written about CO2 ...
Tjis takes the cake- Eric's share of the air , like yours and mine is about 3/4 of a millon tonnes. Adding 600 ppm of CO2 would mean burning a thousand tonnes of lime per capita, and keeping it up long enough for the ocean to re-equiibrate -
That's roughly $10,000 for the limestone , plus $5,000 for the coal to burn it plus operating expenses , per capita per annum for generations to come. As gross global GNP stands around $16,000 , Eric's definition of "surprisingly affordable" is in the vicinity of all the money in the world.
