We can expect to see an ice-free Arctic Ocean within 50 years, according to researchers at the University of California's Center for Climate Science, who say they've improved and narrowed past projections of when the Arctic might be free of sea ice.
Projections have varied from as early as 2026 to as distant as 2132.
Now, according to
research published in the journal Nature Climate Change, the
Arctic could be "functionally ice-free" by September 2044 — and no later than 2067 — assuming no changes to global carbon emissions.
