A fair-enough report from al-Jazeera
As
the world warms, the ice melts
Storms
over the Arctic Ocean (top), causing rain (green) and snow (blue) to
fall to the north of Greenland (bottom).
Rain
can have a devastating impact on the sea ice, due to kinetic
energy breaking up the ice as it gets hit. This can fragment the ice,
resulting in water that is warmer than the ice to melt it both at the
top and at the sides, in addition to melting that occurs at the
bottom due to ocean heat warming the ice from below and melting that
occurs at the top due to sunlight warming the ice from above.
Furthermore,
where the rainwater stays on top of the sea ice, pools of water will
form, fed by rainwater and meltwater. This will darken the surface.
Melting sea ice is also darker in color and, where sea ice melts away
altogether, even darker water will emerge. As a result, less sunlight
is getting reflected back into space and more sunlight is instead
absorbed.

Arctic
sea ice extent takes a dive. On August 27, 2016, extent was 4.8
million square km, according to the NSIDC.
