Warm European seas lure swimmers as ecosystems reel from warming, study finds

Europe’s oceans are warming rapidly due to climate change, adding about 2°C to the Mediterranean this summer and roughly 1.3–1.4°C to Western European waters, driving widespread marine heatwaves and ecological disruption. Species are shifting north, food webs are reassembling, and coastal fisheries and aquaculture face risks, with potential land heat implications from higher sea surface temperatures. While warmer seas may attract swimmers in cooler countries, the deeper ecological costs are substantial.
