The big melt: sea ice in a changing climate

Scientists are currently puzzled by the behavior of Arctic sea ice: Following a sharp and unexpected decline in summer 2007, the ice-covered area has increased both in 2008 and in 2009. At MPI for Meteorology, scientists carry out research to understand these ups and downs. They also examine what their results mean for the future evolution of the polar bear's habitat. For their studies, the researchers use sophisticated computer models, but they also carry out field measurements in the Arctic to better understand the physical properties of sea ice.
