The Arctic is warming at twice the rate of the rest of the planet in response to our changing climate. The sea ice which covers the Arctic Ocean acts to cool the Northern Hemisphere as it is very reflective, greatly reducing the warming influence of the sun's rays.
However, over the past couple of decades we have seen a big decrease in Arctic Sea ice extent, particular in late summer when the areal extent reaches it's minimum. The sea ice extent in 2020 was the second lowest on record, higher than the 2012 record but slightly less than the 2019 minimum.
Whilst atmospheric warming has traditionally dominated summer sea ice loss, we will present evidence of the growing influence of the heat being carried into the Arctic Ocean from the Atlantic Ocean, via the Fram Strait and Barents Sea, in melting the sea ice. This includes a regime shift in winter sea ice cover in the southern Barents Sea and the oceanic heat flux over taking the atmospheric warming in the eastern Arctic Ocean.
This lecture will be given by Professor Tom Rippeth from Bangor University.
This event has been organised by the South comittee.
