Live Chat: Can Geoengineering Save the World?
30 May 2012 8:16 am
See below for the chat box. Join us each Thursday at 3 p.m. EDT for a live conversation with leading scientists and expert reporters.
For a decade, Canadian physicist David Keith has led the effort to explore the controversial idea of geoengineering, the deliberate tinkering of the planet to curb the effects of climate change. Ideas have ranged from sucking carbon dioxide out of the atmosphere to seeding Earth’s stratosphere with sunlight-blocking particles. How practical are such approaches? What are the geopolitical implications? And what are the risks of these approaches compared to staying on our present course?
Join us for a live chat at 3 p.m. EDT on Thursday, 31 May, on this page. You can leave your questions in the comment box below before the chat starts. The full text of the chat will be archived on this page
