When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists ...

A group of international scientists led by Cornell University is—more rigorously and systematically than ever before—evaluating if and how the stratosphere could be made just a little bit "brighter," reflecting more incoming ...

Tinkering with the planet's air to cool Earth's ever-warming climate is inching closer to reality enough so that two different high-powered groups—one of scientists and one of former world leaders—are trying to come up ...

A group of 60 scientists called for a moratorium on solar geoengineering last month, including technologies such as stratospheric aerosol injection (SAI). This involves a fleet of airplanes releasing aerosol particles—which ...
