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 ...

Solar geoengineering, a bunch of techniques that aim to mask some effects of climate change by blocking sunlight, isn’t on the agenda for this month’s COP30, the U.N. climate conference. It ought to ...

As climate targets slip out of reach and heat records fall year after year, a once-fringe idea is moving toward center stage: deliberately dimming the sunlight that reaches Earth to cool the planet.

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 ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. The west coast of North America is one area the Marine Cloud Brightening Program has considered for a 3,900-square mile solar ...

Global warming continues to surge, driven by rising greenhouse gas emissions. Scientists across the world agree: unless these emissions fall to net zero, the effects of climate change will grow more ...

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, ...

Injecting sun-reflecting particles into the atmosphere could lower global temperatures, but sudden changes or termination ...

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

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 ...
