New Ice Thickness Map of the Arctic Unveiled

The first map of sea-ice thickness from ESA’s CryoSat mission was revealed today at the Paris Air and Space Show. This new information is set to change our understanding of the complex relationship between ice and climate.
From an altitude of just over 700 km and reaching unprecedented latitudes of 88º, CryoSat has spent the last seven months delivering precise measurements to study changes in the thickness of Earth’s ice.

Polar Bear Extinction?

Polar bears could be extinct in 100 years if climate change continues to melt the North Pole's ice. The North Pole's 'permanent' ice is melting by 10% each year and is likely to speed up as the white ice no longer reflects the sun's heat.

Bears need the ice to feed. They can smell the seals under the ice and can break through it to catch them, or just wait for them to come up for air. Polar bears have always been able to survive the summers with little food, but now, with longer between the ice forming, they are suffering.
