CLIMAREST will be developed on a latitudinal gradient

However, not all the Atlantic [...] In the last few decades, the Arctic sea ice has receded ever further, including increasingly in winter when the extent of sea ice is at its most prominent. One of the main drivers of this development is

The research team found no evidence of such a permanent, pan-Arctic ice [...] ice shelf. Instead, the Arctic Ocean appears to have been covered by seasonal sea ice, allowing open water—and life—to persist even during the harshest glacial periods of the past 750,000 years.
