Sea ice
ESA TV Exchanges
Large expanses of ice in the frozen north are slowly beginning to melt. Global warming is driving back the ice cap - fuelled in part by human activity. The polar bear has become both a symbol and a victim of the process of climate change. Sophisticated earth observation satellites provide a vital monitoring tool if we are going to better understand and manage the changes going on around us in future.

""(even) If the polar bear disappears, we will have good food, we will have medicines, we will be wealthy in Europe, I am sure. But we will be also much poorer if this beautiful and important ecosystem disappears.""

This model, from the Max Planck institute for Meteorology in Hamburg, shows how summer sea ice is disappearing at an accelerating rate.
