*Spewing sulfur dioxide into atmosphere could slow warming, says research*

 On earth, sulfur dioxide contributes to acid rain and harms human hearts
and lungs -- but if injected into the stratosphere, says new research in *
Science*, it could shade the sun's rays and keep global warming at bay. Hey,
if volcanoes can spew it, why can't we? "I'm not suggesting we don't reduce
our dependence on fossil fuels for energy," says study author Tom Wigley.
"But ... can we make it economically and technologically easier by doing
something that's also technology, which may be cost-effective?" According to
Wigley's computer models, volcanic-scale sulfur-spewing every one to four
years could keep global temperatures close to constant for 40 to 50 years,
even if carbon emissions continue to increase. The scheme would have plenty
of barriers to overcome: For one, planes would be the most sensible
carriers, but the magnitude of the release would require more than the
current global commercial airline fleet. And for two, it's totally crazy.
