EU Report: Arctic Sea Ice Down 490k km2/Decade; Med and Black Sea Record Heatwaves

The Copernicus Marine Service report confirms a long-term decline in Arctic sea ice extent of ~490,000 km2 per decade (1979-2022) and unprecedented marine heatwaves in the Mediterranean and Black Seas. The findings are consistent with established climate trends, but the report's release adds official EU-level documentation. This matters as it underscores accelerating climate impacts on marine systems, with implications for regional ecosystems and coastal economies.
