Vast sums of private and public money are now chasing a once-fringe idea: deliberately reflecting a slice of sunlight back ...

We must not let geoengineering be shaped behind closed doors. Climate justice demands an inclusive approach ...

SALT LAKE CITY — You can see them in the sky, the airplanes carrying customers or cargo. But maybe these planes are doing something else: spraying chemicals to bounce the heat of the sun back into the ...

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. Solar geoengineering startups are getting serious Solar ...

Companies are coming up with plans to block out the sun - Private companies are jumping into the race to deploy particles to ...

Reusable rockets that deliver sun-reflecting aerosols to the top of the stratosphere could cool the planet – with fewer negative side effects than lower-altitude solar geoengineering. But a fleet of ...

Outside actors are increasingly looking to test speculative climate fixes such as solar geoengineering in African countries. But this potentially dangerous course of action would divert financing and ...

A Royal Society report outlines the state of the science but makes no concrete policy recommendations. Futuristic sun-reflecting technology could be effective at cooling the planet, says the United ...

The potential role of solar geoengineering strategies in addressing global warming is a matter of current scientific and societal debate. Some strategies could reduce the surface temperature of Earth, ...

Ship engines spew particles that drift into the lower atmosphere, creating linear, reflective clouds called ship tracks, which can cool the ocean. FSU research asks whether the phenomenon could ...

For years, climate scientists have resisted geoengineering as a way to address climate change, saying that the best way to reduce greenhouse gas emissions is to stop burning fossil fuels. Scientists ...
