But it may be disrupting species' breeding patterns and could bring an influx of jellyfish that like warmer waters, including the huge barrel jellyfish, to seas and beaches.It could also cause harmful algae to grow out of control, creating wide patches of green algae that can poison other life.

"We will be watching closely to monitor the impacts of the current UK heatwave on marine life and fisheries," John Pinnegar, Lead Advisor on Climate Change at the UK Centre for Environment, Fisheries and Aquaculture Science.Previous heatwaves have caused harmful blooms of algae and in 2018 caused mass mortality among mussels.In 2023, jellyfish sightings increased by 32% following a marine heatwave with temperatures 3-4C above average.

The heat could also encourage different fish to move into UK waters, including the bluefin tuna, potentially increasing the amount of fish to catch.Normally marine heatwaves last around two weeks, so scientists are surprised at how long this one is persisting.

"It is exceptional. We are about two and half months in, which is very long," says Dr Berthou.

Higher sea temperatures can push up land temperatures too, as sea breezes carry the heat off the ocean.Beyond the physical damage, which may or may not be as great as analysts here are assessing, Operation Spider's Web sends another critical message, not just to Russia but also to Ukraine's western allies.

My colleague Svyatoslav Khomenko, writing for the BBC Ukrainian Service website, recalls a recent encounter with a government official in Kyiv.The official was frustrated.

"The biggest problem," the official told Svyatoslav, "is that the Americans have convinced themselves we've already lost the war. And from that assumption everything else follows."Ukrainian defence journalist Illia Ponomarenko, posting on X, puts it another way, with a pointed reference to President Volodymyr Zelensky's infamous Oval office encounter with Donald Trump.
