Resorts on Spain’s Costa Brava struggle with invasion of jellyfish as seas warm

Stings needing medical attention surge by 41% as rising sea temperatures due to the climate crisis boost reproduction

Costa Brava resorts in Spain's north-east are struggling to cope with an influx of jellyfish as rising sea temperatures facilitate reproduction and drive species farther north.

Between May and August almost 7,500 people on the Catalan coast sought medical attention for jellyfish stings - a 41% increase on last year. The stings are painful and can have unpleasant consequences for anyone with compromised immunity.
