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 ...

There are practical limits to the height at which aerosols may be deployed in the atmosphere to deflect incoming sunlight and countervail global warming. Very high-altitude injections might be more effective, but such climate ...

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 ...

How can the world combat the continued rise in global temperatures? How about shading the Earth from a portion of the sun's heat by injecting the stratosphere with reflective aerosols? After all, volcanoes do essentially ...
