Description
If global surface temperatures rise by 5.7 degrees Celsius (IPCC SSP5-8.5 Fossil-Fueled Development scenario), Antarctica could contribute between 3 and 34 centimetres to global sea-level by the year 2100. In fact, some studies suggest that the rise may be more than 1 metre! This is huge uncertainty in predictions for just one of many possible climate scenarios. This reason for this uncertainty is that there is so much that we still don't know about Antarctica's complex systems.
So what are some of the biggest questions at the cutting edge research into Antarctica and sea level rise? And how are geographers working to address them?
To investigate this, we team up with Prof Adrian Luckman, Dr Katie Miles and Dr David Small; three geographers leading major research projects in Antarctica today, to improve our predictions of future sea-level rise. We explore how a new understanding of ice shelves is helping determine the future of these important, protective buffers, and how cosmic rays can help us test the accuracy of computer model simulations.
Considering taking geography and geoscience further at university? Use this video to see how the geography you are learning in school is connected to addressing major global challenges!
