Global warming could be reversed using a combination of burning trees and crops for energy, and capturing and storing carbon dioxide underground (CCS), according to an analysis by scientists. But experts cautioned that trying such an approach after temperatures had passed dangerous levels could be problematic, as climate change reduced the number of trees available for “bioenergy.”

The bioenergy and CCS method was the most cost-effective way of tackling carbon emissions, said the team at Chalmers University of Technology in Sweden, publishing their research in the journal Environmental Research Letters on Thursday.

July 1, 2013 — A slum on the outskirts of Accra, Ghana, received major media attention in 2010 and 2011 when the outside world realized where computers go to die. In an area called Agbogbloshie, impoverished residents were burning broken electronic parts, discarded and dumped by wealthier nations, to extract the metal components. Crouched around bonfires, they inhaled toxic smoke and unwittingly leached heavy metals into a nearby river, just to eke out a living.

Harvard undergraduate Rachel Field '12, an engineering sciences concentrator, read the news reports and devoted her senior thesis project to addressing the problem.
