Climate Researchers Warn: Warmer Climate Could Lead To “Cold Waves Across Northern Europe”!

In a recent open letter, researchers warned that a warmer Arctic could lead to cold waves across Northern Europe – due to “complex feedback mechanisms”.

According to Forschung & Wissen here, an international group of renowned scientists recently published an open letter (PDF) stating that the melting of ice in the Arctic could disrupt ocean currents in the Atlantic, and thus have “devastating and irreversible impacts especially for Nordic countries, but also for other parts of the world.”

According to their publication in the journal Nature Communications, October 2024, doi: 10.1038/s41467-024-53401-3, melting of sea ice during the last interglacial significantly impacted the density and salinity of seawater, and thus led to significant changes in ocean currents and heat distribution in the oceans.

The researchers looked at sediment cores collected in the North Sea and reconstructed surface temperatures and salinity and found that these processes have led to a significant drop in temperature in northern Europe.

According to Mohamed Ezat: “Our discovery that the increased melting of Arctic sea ice in the Earth’s past probably led to significant cooling in northern Europe is alarming.”

He adds:  “The impacts particularly on Nordic Countries would likely be catastrophic, including major cooling in the region while surrounding regions warm.  This would be an enlargement and deepening of the ‘cold blob’ that already has developed over the subpolar Atlantic Ocean and likely lead to unprecedented extreme weather.”
