Termination shock / Neal Stephenson.

In the near-future world, the greenhouse effect has inexorably resulted in a whirling-dervish troposphere of superstorms, rising sea levels, global flooding, merciless heat waves, and virulent, deadly pandemics. One man has a Big Idea for reversing global warming, a master plan perhaps best described as "elemental". But will it work? And just as important, what are the consequences for the planet and all of humanity should it be applied? Ranging from the Texas heartland to the Dutch royal palace in the Hague, from the snow-capped peaks of the Himalayas to the sunbaked Chihuahuan Desert, Termination Shock brings together a disparate group of characters from different cultures and continents who grapple with the real-life repercussions of global warming. Ultimately, it asks the question: Might the cure be worse than the disease?
