• CORRECTIONS: This story was updated on Dec. 4, 2012, to provide the correct unit of measure for the black carbon emissions: gigagrams, not gigatons. The story was updated on Nov. 30, 2012, to explain that it was the study authors’ idea that kerosene lamps represented a possible missing source of black carbon. The description of how the researchers measured black carbon levels in people’s homes was also corrected.

Kerosene lamps glow nightly in communities across the developing world. New research shows that these tiny lights have a greater impact than expected on climate (Environ. Sci. Technol., DOI: 10.1021/es302697h). Inefficient lamps burning kerosene release about 270 gigagrams of black carbon particulate matter into the atmosphere every year, the researchers estimate. This level of emissions is similar . . .
