proposals suggested thus far

Leonard Ornstein, a biologist at the Mount Sinai School of Medicine, and David Rind and Igor Aleinov, researchers at NASA’s Goddard Institute for Space Studies, have describe a plan to pump desalinated seawater from the coast to the Sahara Desert and Australian Outback. Desalination plants would acquire the needed energy from massive solar farms. The water would be used to irrigate crops, such as Eucalyptus grandis. Over time, these trees would replenish the soil and facilitate more rainfall. Depending on the size of the forest, it could fix as much as 8 million tons of atmospheric CO2. So not only would it make vast regions of land fertile and habitable, it could potentially end global warming
