Sulfur stalls surface temperature rise

Findings explain decade without warming

A new study demonstrates why global surface temperatures defied a decades-long trend and didn’t continue to rise between 1998 and 2008: Pollution-spewing, coal-burning power plants in Asia, while emitting warming greenhouse gases, simultaneously sent cooling sulfur particles into the atmosphere.

During that decade — sometimes cited as evidence to deny global warming — these Asian emissions mostly balanced one another and dampened the effects of natural cooling cycles associated with the sun a...
