Summary

Heatwaves Threaten

Marine heatwaves covered about 90 % of the Bay of Biscay and 80 % of the Western Mediterranean.
World Weather Attribution found climate change added 2 °C to the Mediterranean and 1.4 °C to the Bay of Biscay.
John Bruno reported jellyfish blooms clog cooling intakes at French nuclear power stations.
European Centre for Disease Prevention and Control warned higher sea temperatures raise vibriosis risk along coasts.

Summary

German Researchers Forecast

German researchers at the Potsdam Institute project Europe’s wildfire-affected area could triple by 2100.
Under a low-emissions pathway (~1.8 °C), burned land is forecast to rise 39 %.
A high-emissions pathway (~3.6 °C) could increase burned area by about 192 %.
Improved fire management could cut burned area by 92 % in a 1.8 °C future.
By 12 August, 550,000 ha burned in EU, 2.5 × 20-year average, with 20,000 evacuations and 20+ deaths in Spain and Greece.
