Climate Change Signals: French Cool Spell and Weakening Gulf Stream

Brief periods of cooler weather have been recorded across France and the British Isles, but these local anomalies do not alter the broader warming trend. Global surface‑air temperature in early June 2026 was 0.6 °C above the 1991‑2020 climatological average, the second‑highest on record, confirming that short‑term, regional coolness is outweighed by sustained planetary heat.

A new study published in *Geophysical Research Letters* identifies a “cold blob” of fresher, cooler water south of Greenland and Iceland. The authors link this feature to a possible slowdown of the Atlantic Meridional Overturning Circulation (AMOC), which transports heat northward via the Gulf Stream. Reduced heat transport could modestly affect European climate, though the research does not predict an imminent collapse of the system.
