Global warming pause linked to sulfur in China

By RANDOLPH E. SCHMID, AP Science Writer – Jul 4, 2011

WASHINGTON (AP) — Scientists have come up with a possible explanation for why the rise in Earth's temperature paused for a bit during the 2000s, one of the hottest decades on record.

The answer seems counterintuitive. It's all that sulfur pollution in the air from China's massive coal-burning, according to a new study.

Sulfur particles in the air deflect the sun's rays and can temporarily cool things down a bit. That can happen even as coal-burning produces the carbon dioxide that contributes to global warming.

"People normally just focus on the warming effect of CO2 (carbon dioxide), but during the Chinese economic expansion there was a huge increase in sulfur emissions," which have a cooling effect, explained Robert K. Kaufmann of Boston University. He's the lead author of the study published Monday in Proceedings of the National Academy of Science.
