In a recent open letter, researchers warned that Arctic warming could lead to cold snaps across Northern Europe due to “complex feedback mechanisms.”
According to Forschung & Wissen, an international group of prominent scientists recently published an open letter (PDF) stating that melting Arctic ice could disrupt Atlantic ocean currents, resulting in “devastating and irreversible effects, especially in northern Europe.” country” and also applies to other parts of the world. “

According to their article published in the October 2024 issue of Nature Communicationstwo: 10.1038/s41467-024-53401-3, The melting of sea ice during the last interglacial period significantly affected the density and salinity of seawater, leading to significant changes in ocean currents and ocean heat distribution.
The researchers looked at sediment cores collected in the North Sea and reconstructed surface temperatures and salinity, finding that these processes caused a significant drop in temperatures in northern Europe.
“Our finding that increased melting of Arctic sea ice in Earth's past may have contributed to significant cooling in northern Europe is alarming,” said Mohamed Ezhat.
He added: “The effects on the Nordic countries in particular could be catastrophic, including significant cooling in the region and warming in surrounding areas. This would be an expansion and deepening of the 'cold spot' already forming over the subpolar Atlantic and could leading to unprecedented extreme weather.
