It is still a bit of a mystery how exactly they will affect marine life, but the signs so far are not good."The interesting thing is that this started in winter and spring, when most people assume marine heatwaves are only in summer," says Dr Jacobs.

People swimming off the west coast of the UK and Ireland may notice the warmer temperatures, although the waters are still cooler than at their peak in late summer.The worst impacts on species are likely to have been avoided for now because the temperatures have not gone above the upper limit that marine life can tolerate, explains Dr Jacobs.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 WTO said it expected global merchandise trade to decline by 0.2% in 2025 as a result, having previously projected it would grow by 2.7 per cent this year.

The trade court ruling - if it holds - might help global trade perform somewhat better than this.But the dampening impact of uncertainty regarding whether US tariffs will materialise or not remains.

The bottom line is that many economists think trade will still be very badly affected this year."Trump's trade war is not over – not by a long shot," is the verdict of Grace Fan of the consultancy TS Lombard.
