Arctic sea ice at second-lowest level in satellite record: scientists

Last Updated Sep 21, 2020 at 2:24 pm EDT

Satellite pictures show Arctic sea ice is at its second-lowest level in more than four decades.

And scientists say they believe the defining feature of life in northern waters could shrink even further before the melt season is over.

The U.S.-based National Snow and Ice Data Centre has decided that today is likely to be when the overall level of sea ice across the Arctic stops melting and starts growing again.

Centre director Mark Serreze says the amount of Arctic sea ice is at least 1.5 million fewer square kilometres less than the average.

The ice barely beats that from 2012, the year with the all-time lowest level in the 42 years satellites have been photographing the Arctic.

Sea ice is a crucial factor in Arctic ecosystems, determining the fate of everything from one-celled animals to polar bears.

It is also thought by many to have a strong role in southern weather patterns.
