Foreign Affairs: Geoengineering Research Is Needed

The journal Foreign Affairs publishes "The Geoengineering Option: A Last Resort Against Global Warming?" by David Victor, et al. This article makes a strong case for the need of geoengineering research because emissions reductions are not enough to prevent catastrophic climate change. 

"Humans have already engaged in a dangerous geophysical experiment by pumping massive amounts of carbon dioxide and other greenhouse gases into the atmosphere. The best and safest strategy for reversing climate change is to halt this buildup of greenhouse gases, but this solution will take time, and it involves myriad practical and political difficulties. Meanwhile, the dangers are mounting. In a few decades, the option of geoengineering could look less ugly for some countries than unchecked changes in the climate. Nor is it impossible that later in the century the planet will experience a climatic disaster that puts ecosystems and human prosperity at risk. It is time to take geoengineering out of the closet -- to better control the risk of unilateral action and also to know the costs and consequences of its use so that the nations of the world can collectively decide whether to raise the shield if they think the planet needs it.
