Retailers have been increasingly providing recycling bins in shops so the devices can be disposed of properly.
"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.
That happened in May 2024 when a short marine heatwave contributed "significantly" to above-average land temperatures, according to the Met Office.
In some parts of the world - including Australia, the US and the Pacific - marine heatwaves can destroy coral reefs or local fisheries, as well as vital seagrass meadows."I know that prior to the first line of treatment going down it was expected I'd live five or six years, maybe more.
