The tipping point for irreversible global warming may have already been triggered, the scientist who led the biggest- ever expedition to the Arctic warned on Tuesday.
The disappearance of summer sea ice in the Arctic is one of the first landmines in this minefield, one of the tipping points that we set off first when we push warming too far. The expedition involving 300 scientists from 20 countries. The expedition returned to Germany in October after 389 days drifting through the Arctic, bringing home devastating proof of a dying Arctic Ocean.
Summarising their first findings, scientists found that the Arctic sea had retreated faster in the spring of 2020 than since the beginning of records and that the spread of the sea ice in the summer was the only half as large as decades ago.
The ice was only half as thick and temperatures measured 10 degrees higher than during the Fram expedition undertaken in the 1890s.
