The Double-Edged Sword of Geoengineering

Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

Climate News Roundup — Week of 6/14

Bill Gates funds cloud-whitening effort to reduce global warming.  USA Today Bill Gates is funding research into whether or not it is effective and feasible to increase the albedo of atmospheric clouds by spray sea mist high into the atmosphere. The plan, spearheaded by Silicon Valley inventor Armand Neukermans, is a relatively benign method of… read more
