World’s sea-ice falls to record low

The world’s frozen oceans, which help to keep the planet cool, currently
have less ice than ever previously recorded, satellite data shows. Sea-ice
around the north and south poles acts like a giant mirror by reflecting
much of the Sun’s energy back into space. But as rising temperatures cause
this bright layer to shrink, the dark ocean below can absorb more heat,
warming the planet further. This latest sea-ice low appears to have been
driven by a combination of warm air, warm seas and winds breaking apart the
ice. Over the 5 days to 13 February, the combined extent of Arctic and
Antarctic sea-ice was 15.76 million sq km (6.08 million sq miles),
according to BBC analysis of data from the US National Snow and Ice Data
Center (NSIDC). This breaks the previous 5-day record low of 15.93 million
sq km (6.15 million sq miles) from January-February 2023.
