Millions of customers, surfers and bathers have joined a chorus that former pop star Feargal Sharkey has been singing for years - that the sector is a “chaotic shambles”.

At a beach just south of Tel Aviv, bathers cheered and applauded when a lifeguard first announced rumours of the death over a loudspeaker.

The first warning signs were in the Caribbean last year when bathers found the water off the coast of Florida was as warm as a hot tub.

When I joined the team putting the net down early one morning bathers immediately came into the water, bobbing up and down in the water next to the barrier.
