But exactly how much, and how fast, remains unclear. Scientific understanding of ice sheet processes, and of the variability of the forces that affect ice sheets, is incredibly limited. This is largely because much of the ice sheets are in very remote and harsh environments, and so difficult to access. This lack of information is one of the main sources of uncertainty in the models used to estimate ice mass loss. The project includes experts in ice sheet and climate modelling and observations.
It produces computer simulations of what might happen if the polar regions melt under different climate scenarios , to improve projections of sea level rise. The project also investigates ice sheet—climate feedbacks. In other words, it looks at how processes in the oceans and atmosphere will affect the Antarctic and Greenland ice sheets, including whether the changes might cause them to collapse — leading to large and sudden increases in sea level.

For 60 years, Antarctica has seen strong global cooperation. But without hitting ambitious targets at COP26, it will significantly disrupt global systems.
Future sea level rise poses challenges like human displacement, infrastructure loss, interference with agriculture and coastal habitat degradation. I accept. Africa 54 - November 11, VOA Africa Listen live. VOA Newscasts Latest program. VOA Newscasts. Previous Next. June 13, AM.
