Welcome to Week 3 - ‘What we see in the data: Ice Sheet dynamics and change’’. In this first video of the week, Professor Steffen provides a broad overview of some of the key findings revealed by satellite data about the Greenland ice sheet in recent decades.

He sets out the compelling evidence for significant change in temperatures that impact on feedback loops, and the consequential increase in the rate of melting from the surface and beneath the Greenland ice sheet.

Optional Mini Task:

Take a look at the Arctic Observing Viewer. Deselect the “Ship Tracks” and “Other” layers on the layers menu to the right of your screen. Use the search function in the top menu to locate Greenland by selecting country and then Greenland. How do the data collection sites, stations and observatories appear to be distributed? Where do you think new sites could be placed to be of benefit and why?
