I have a chapter on how to reverse global warming in my book. What we may need is reverse combustion. You convert CO2 into carbon and oxygen, release the oxygen, and bury the carbon, either as solid (like coal) or as hydrocarbon (synthetic oil). Whichever is cheaper. A liquid might be easier to deal with, for the same reason oil is more convenient than coal. However, I not think this is necessary. A much simpler solution is available that has many other benefits. We can use large scale desalination to grow crops and forests in some desert areas. Then we sequester the deadwood from the resulting climax forests. Depending on the forest it takes 50 to 100 years to reach climax, so there is no rush. I estimated approximately how much land and how many desalination plants this would take. The numbers are not that high. - Jed
