Climate change is flooding the Arctic with light – and new species In partnership with
Saturday, December 12th 2020, 6:20 pm - Increased human activity will have a major impact in the Arctic s various species in the coming decades.
At just over 14 million square kilometres, the Arctic Ocean is the smallest and shallowest of the world’s oceans. It is also the coldest. An expansive raft of sea ice floats near its centre, expanding in the long, cold, dark winter, and contracting in the summer, as the Sun climbs higher in the sky.
Every year, usually in September, the sea ice cover shrinks to its lowest level. The tally in 2020 was a meagre 3.74 million square kilometres, the second-smallest measurement in 42 years, and roughly half of what it was in 1980. Each year, as the climate warms, the Arctic is holding onto less and less ice.
