Greenhouse gas emissions are pouring out at unprecedented levels, and the numbers are still rising. But with climate skeptics (and their allies in industry and government) thwarting conservationists’ efforts, some scientists are working to develop a back-up plan: using technology to “geoengineer” the Earth’s atmosphere and reduce the impacts of climate change.

But geoengineering is seen by some as a distraction from the real challenge of climate change in much of the scientific community. Critics say it’s a solution that diverts attention away from the real challenge, which is finding a way for the world to drastically reduce the amount of man-made carbon that its pumping into the atmosphere.

Shane Smith and Ben Anderson took an in-depth look at how this technology would work — and how effective this radical (and potentially dangerous) plan could be.
