Antarctic Sea Ice Shrank to Lowest Extent on Record in January
--------------------------------------------------------------

In climate news, researchers reported Wednesday that the area of the
Antarctic Ocean covered by sea ice shrank to its lowest extent on record
for January, in the latest sign that global heating is accelerating. The
European Union's Copernicus climate monitor also reported Arctic sea ice
was at its third-lowest concentration on record for January. Melting sea
ice can help accelerate climate change, as dark ocean water absorbs
heat, while white sea ice reflects up to 90% of the sun's energy back
into space.
