Mirrors in space? Artificial volcanos? Refreezing the Arctic?! Can we? Will we? SHOULD we?

Dave & Ol embark on a terrifying interview with geoengineering expert, Duncan McLaren.

We've also got some Babble from an unholy Caledonian alliance, and an Anti-Inhofe Inhofe from Down Under.

Sustainababble is your weekly comedy podcast about politics, prattle and the planet.

Music by Dicky Moore from Bearcraft and Dream Themes.
