This would appear to be one of the largest single Russian drone attacks so far. Ukraine says it "neutralised" 385 aerial targets.

"It started in the North Sea and the Celtic Sea. Now the North Sea has cooled down a bit but the west of Ireland is extremely hot," says Dr Berthou.One of the warmest springs on record is driving the surge, as high temperatures and weak winds warm the top layer of the ocean.

Marine heatwaves in the UK are thought to be a relatively new phenomenon but they are expected to increase in frequency and intensity.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.The US Court of International Trade on Wednesday struck down President Donald Trump's tariffs imposed under the 1977 International Emergency Economic Powers Act (IEEPA).

The court ruled IEEPA did not give the president the authority to impose certain tariffs.This affects the "fentanyl" tariffs imposed by the White House on Canada, Mexico, China since Trump returned to the White House. These tariffs were brought in to curb smuggling of the narcotic into the US.

It also affects the so-called "Liberation Day" tariffs announced on 2 April, including the universal 10% baseline tariff on all imports to the US.However, the ruling does not affect the Trump administration's 25% "sectoral" tariffs on steel and aluminium imports and also his 25% additional tariffs on cars and car part imports, as these were implemented under a different legal justification.
