Pollution in the atmosphere is having an unexpected consequence, scientists say—it's helping to cool the climate, masking some of the global warming that's occurred so far.

 

That means efforts worldwide to clean up the air may cause an increase in warming, as well as other climate effects, as this pollution disappears.

 

New research is helping to quantify just how big that effect might be. A study published this month in the journal Geophysical Research Letters suggests that eliminating the human emission of aerosols—tiny, air-polluting particles often released by industrial activities—could result in additional global warming of anywhere from half a degree to 1 degree Celsius.
