Scientists believe that global warming could be reversed with the right implementation of energy management and carbon reduction, according to research published in the journal Environmental Research Letters. Specifically the Swedish researchers recommended burning more trees and crops for energy while storing carbon dioxide underground.
Using that approach to reduce global warming would be the most cost-effective worldwide, the team at Chalmers University of Technology said. The strategy could also offset and possibly reverse emissions from other fossil fuels.
The carbon capture and storage idea has been tested successfully on a smaller scale, but not so on a global level. Some environmentalists doubt the benefits of burning trees, saying that the emissions over time could be worse than those from coal burning.
