sea ice in the Arctic has several key functions in the Earth's climate system: it reflects large parts of the solar radiation, thus slowing down global warming and it drives global ocean and air currents [...] outside our window. How the sea ice retreats or expands depends largely on the energy balance of the Arctic Ocean surface.
