Seeding Atmosphere w/ Sulfur Not A Good Idea

A controversial theory proposes mimicking volcanoes to fight global warming. But throwing sulfur particles into the sky may do more harm than good, a new study says.

The temporary solution would pump particles of sulfur high into the atmosphere—simulating the effect of a massive volcano by blocking out some of the sun's rays. This intervention, advocates argue, would buy a little time to reduce greenhouse gas emissions.

But as well as cooling the planet, the sulfur particles would reduce rainfall and cause serious global drought, a new study says.

"It is a Band-Aid fix that does not work," said study co-author Kevin Trenberth of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.

It's just one of several drastic measures proposed to combat global warming, now that most scientists are in agreement that carbon dioxide, primarily from burning fossil fuels, is changing Earth's climate.

I can't help but think that sulfur would cause other issues as well, but it is pretty high up in the atmosphere.
