A marine heatwave is defined as sea temperatures that exceed the seasonal threshold for more than five consecutive days. In the UK the marine heatwave threshold for May is 11.3C.On 19 May the average sea surface temperature reached 12.69C.

"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.All of which is good for Burgundy because while general red wine consumption just keeps going down, white is holding firm, and sparkling is going up.

Also, the reds that come out of Burgundy are, according to Mr Labet, the kind consumers increasingly want, as they are typically lighter than New World reds."What is interesting to see is that there is a strong de-consumption of what we call the big reds, made in the US. Wines with a lot of alcohol, aged in new wood."

Less sun and lower temperatures in Burgundy, even with climate change, means less sugar in the grapes and lower alcohol content.Mr Labet remembers when, for 18 months of his first presidency, Donald Trump hit European wine with a 25% import tariff during a dispute over airlines.
