New research from scientists at UCL and the University of Leeds shows an unusually cool summer in the Arctic in 2013 led to a boost in sea ice. The research, carried out with the European Space Agency’s CryoSat-2, gives researchers of the fluctuations in ice between years, and suggests that pack ice in the northern hemisphere is more sensitive to changes in summer melting than it is to winter cooling.
