8/20/2026

Summary

World Weather Attribution Reports

World Weather Attribution reported carbon pollution expanded marine heatwaves across European waters in 2026.
Some seas reached temperatures up to 6 °C above normal during the hottest two-week periods.
Scientists said two-thirds of the excess heat stemmed from climate breakdown, warming the Mediterranean by 2 °C.
Marine heatwaves covered 90 % of the Bay of Biscay/Iberian coast and 80 % of the western Mediterranean.
The extreme ocean heat threatens corals, macroalgae, fish and seabirds.
