Can Geoengineering Combat Climate Change?
October 18th, 2011 | by Silvio Marcacci
Climate change threatens an increasing list of worst-case scenarios: melting ice caps, rising sea levels, longer droughts, and more violent storms. Climate scientists have largely focused on reducing emissions to counter global warming, but a growing number view geoengineering as the Earth’s last, best line of defense. However, the concept is controversial and unproven, and it’s unclear if it could work. energyNOW! correspondent Josh Zepps explores geoengineering, from simple measures to complex atmospheric efforts, to find out if it can combat climate change.
