Geoengineering: Climate-Cheat?

The year is 2090 and humanity is on the brink. Decades of heat waves and droughts have led to massive crop failures, while the oceans are warming and humans can catch fewer and fewer fish. Millions are starving in the tropics and the war for resources is forcing millions more to flee north. As the situation continues to rapidly deteriorate, governments are enacting a contingency plan in an act of desperation. It is far from certain that such a grim scenario will come to pass. But since global leaders have so far failed to do anything about climate change, it can't be ruled out either. So in the near future, it may be necessary to try something radical to slow the rapid pace of climate change: Geoengineering. Interventions on such a huge scale that they could undo centuries of human destruction - or make things much worse. What is geoengineering, is it a valid option, and what if it goes wrong?
