Fig. 1 - S3 SLSTR (15-30.04.2023) - Temperatures surged up to 20°C higher than normal across large parts of Morocco, Algeria, Spain and Portugal.
Temperatures surged up to 20C higher than normal across large parts of the western Mediterranean. Temperatures exceeded 40°C in parts of Morocco and Algeria. In Spain, temperatures reached 38.8C at Córdoba airport.
Fig. 2 - S3 SLSTR (01.05.2023) - Many local April temperature records broken by up to 6°C. It also set a new April record for all of Europe.
In its most rapidly produced study to date, the World Weather Attribution service, which launched in 2014, finds that the heatwave was up to 3.5C hotter than it would have been in a world without climate change.
Fig. 3 - S3 SLSTR (01.05.2023) - NDWI-SM - Affected areas are important fruits exporters, this event is likely to increase food price this year.
Researchers found that climate change made the heatwave at least 100 times more likely. Their study adds that, even in today’s climate, the heatwave was unlikely, with roughly a 0.25% chance of happening in a given year.
