salt

Sprinkling large amounts of salt into the atmosphere could stave off climate change, a group of researchers has proposed. They’ve suggested that, because salt is highly reflective, it could potentially reflect sunlight back into outer space, helping to cool the Earth, they wrote in a report presented at the Lunar and Planetary Science Conference in Texas on March 21. But other climate scientists aren’t so sure. This idea falls into the category of geoengineering — a deliberate, large-scale attempt to change the environment as a means to counteract climate change.
