Atmospheric Aerosols Can Cool Climate

Atmospheric AerosolsClimate engineering using atmospheric aerosols could lead to significant cooling to help offset climate change, according to a new study - but it would still mean greenhouse gas emissions would need to be curbed. Natural emissions of aerosols into the atmosphere from volcanoes have demonstrated this effect in the past.
