An extended bonus episode of the podcast, where we learn more about proposals to slow the rate of ice loss in Greenland - and if it works, in Antarctica - using a local form of geoengineering. Host Rowan Hooper speaks to glaciologist John Moore and environmental social scientist Ilona Mettiäinen, both from the University of Lapland in Finland. They discuss the proposal, which involves building a giant, submerged curtain to stop warm sea water getting underneath the ice sheet. They explore the funding and effort needed to pull off a project as big as this. And they talk about local people’s feelings about preserving the ice, as for any intervention it will be vital to have endorsement from Greenlanders.
