U.N. Climate Chief Says Many Coal Reserves Must Be Left in Ground

United Nations climate chief Christiana Figueres said that coal power can be part of the solution to curbing global warming, but it would require shuttering older coal power plants, advancing carbon capture and storage (CCS) technology, and resolving to leave much of the planet's existing coal reserves in the ground.  Her remarks, given at the International Coal and Climate Summit in Warsaw, are drawing criticism from environmentalists who oppose continued reliance on coal power.
