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 Greenlandās 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 ā 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.

Did your cameras stop working? Why not have footage of the topic?
-
Why (on Earth!) can't BBC afford to send a camera man? Or did they send one? Is there some legal reason for there being 90% of audio with no visuals?
-
I notice that the ice looks dirty which absorbs more heat from sunlight and further increases the melt.
-
Apparently it was by the year 2000, and every 2 years since
-
This took place years ago, the 80ās I believe. The Isaac walten league had a local man present his chartās for a local lake of ice in and ice out on the areas biggest lake. He got back to early 1900ās up to present then, it was completely obvious that things are definitely warming! His chartās laid it out perfectly!
-
If the answer was in the very near future, would it make for a typical cozy announcement on a mainstream media platform?
-
Really wish we could have got video of all the beautiful sounding glaciers you are describing lol.
-
Why is the video a wavy stream of orange and blue blanks - where is the actual video feed?
-
The BBC World service is a radio programme and all they have done is spliced in a few bits of video to make it more interesting. Many of the videos on you tube would be better if we didn't have to look at them.
-
Why are we subjected to that odd looking art?
-
Love your work. Pardon please but does the plethora of internal combustion engine contribute to the melting factor ? Not just automobile but all of it. Lawn equipment,trains, construction equipment, aircraft,boats and shopping ? Can a person effectively make a difference beyond give up the personal ride ?
-
Martyn Trantenās comment, āwe shouldnāt play Godā, resonated. However, the bulk of the planets million and billionaires donāt share this view, obviously, and thatās why we are racing to extinction. š¢
-
Is this a video or a podcast ?
-
I know that the ice wall is decently a problem while it's melting especially when they don't know exactly where the water is going to especially when they are thinking the sea level will rise hugely
-
Thanks for your reporting on this issue. The production quality is not worthy of BBC. The information is good. So, thanks for that. But this may as well have been produced as a written document.
-
I have been living near the salt water for 40 years and I can't see a single inch of sea level rise along my foreshore . The tide levels look the same to me .
-
I must say, I am loving your graphic. I thought it was a chart showing water running over glaciers and melting the ice, but, I realize the glaciers in this animation are actually melting way way slower than the glaciers!
-
28 trips to the Artic, no doubt he's planted a lot of trees to offset his carbon footprint? My question is, how much weight is there in ice, and how much will the land rise once all the Greenland Ice has melted? Are there any concerns about trapped organisms being released and causing us potential harm? Thank you for uploading and sharing.

Wish there was video with this, especially with the purple algea...
-
Also what about the South Atlanic Gyre of freshwater melt. Not mentioned and impact on AMOC.
