How long before all the ice melts? – BBC World Service




We know the Earth’s atmosphere is warming and it’s thanks to us and our taste for fossil fuels. But how quickly is this melting the ice sheets, ice caps, and glaciers that remain on our planet? That’s what listener David wants to know.

With the help of a team of climate scientists in Greenland, Marnie Chesterton goes to find the answer, in an icy landscape that’s ground zero in the story of thawing. She discovers how Greenland’s ice sheet is sliding faster off land, and sees that the tiniest of creatures are darkening the ice surface and accelerating its melt.

CrowdScience explores what we’re in store for when it comes to melting ice. In the lead-up to yet another UN climate conference, we unpack what is contributing to sea level rise – from ice sheets in Greenland and Antarctica, to melting mountain glaciers and warming oceans. There’s a lot of ice at the poles. The question is: how much of it will still be there in the future?

Research Professor and climate scientist Jason Box from the Geological Survey of Denmark and Greenland shows us how much ice Greenland we’ve already committed ourselves to losing, even if we stopped burning all fossil fuels today. His team, including Jakob Jakobsen, show us how these scientists collect all this data that helps feed climate models and helps us all to understand how quickly the seas might rise.

Professor Martyn Trantor from Aarhus University helps us understand why a darkening Greenland ice sheet would only add to the problem of melting. And climate scientist Ruth Mottram from the Danish Meteorological Institute breaks down how the ice is breaking down in Antarctica and other glaciers around the world.
