Scientist: Inject Sulfur into Air to Battle Global Warming
One way to curb global warming is to purposely shoot sulfur into the atmosphere, a scientist suggested today.
The burning of fossil fuels releases carbon dioxide, a greenhouse gas, into the atmosphere. It also releases sulfur that cools the planet by reflecting solar radiation away from Earth.
Most researchers say the warming effect has been winning in recent decades.
Injecting sulfur into the second atmospheric layer closest to Earth would reflect more sunlight back to space and offset greenhouse gas warming, according to Nobel laureate Paul Crutzen from the Max Planck Institute for Chemistry in Germany and the Scripps Institution of Oceanography, University of California at San Diego.
