When volcanoes erupt, they spray particles into the atmosphere that cool the planet for a bit. As we get closer and closer to truly catastrophic global warming, more and more scientists are wondering whether a similar approach, called solar geoengineering, could be necessary. If it works, solar geoengineering could buy us some time to cut emissions and get o ... Show More

Block the sun, save the earth?
Solar geoengineering — the idea of cooling the planet by deflecting the sun’s rays — is so risky that scientists and policy experts can’t even agree on whether to research it.

Stopping geoengineering, by accident
Solar geoengineering is a hot (er, cool?) topic these days. One method involves injecting a form of sulfur into the atmosphere to reflect solar radiation and help reduce global temperatures. But it could also cause unpredictable changes to ozone, rainfall, and ecosystems. So when ... Show More

#32: Billionaire plan to geoengineer the planet; how the moon affects your health; Neuralink’s telepathic pigs
If we’re not going to make the effort to cut carbon emissions, why don’t we manipulate Earth’s climate, forcing it to cool down? Obviously that’s not ideal - but geoengineering, one the most controversial proposals to combat climate change, is back in the spotlight this week.
