#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.

In the pod are New Scientist journalists Rowan Hooper, Valerie Jamieson and Cat de Lange. They’re joined by best-selling author and former New Scientist editor Jo Marchant. 

Silicon Valley billionaires have been linked with a new method for geoengineering the planet, which would aim to reverse ocean acidity and remove carbon dioxide from the atmosphere. But do we really want unilateral decisions being made on issues that affect the entire planet?

The team also discusses the power of the moon - you might think its impact on our health is purely the stuff of folklore, but it turns out it may genuinely affect our physiology. Also on the agenda is Elon Musk’s demonstration of Neuralink, a brain-computer interface recently tested in pigs. The team also explains how to travel through a wormhole without dying, and offers the latest updates on coronavirus, as children around the world go back to school.
