Attack of the jellyfish: Sea creatures shut down ANOTHER power station amid claims climate change has caused population surgeBy Daily Mail Reporter

A huge swarm clogged up the Orot Rabin plant in Hadera, Israel, a day after the Torness nuclear facility in Scotland was closed in a similar incident.
Hadera ran into trouble when jellyfish blocked its seawater supply, which it uses for cooling purposes, forcing officials to use diggers to remove them.

Almost 2,000 beach-goers were stung as they celebrated Independence Day weekend in the surf at Volusia County, Florida.
Beach Patrol spokeswoman Captain Tamara Marris reported the staggering statistics but stressed that no victims were seriously injured.
Amid soaring temperatures in the sunshine state, Jellyfish targeted sunseekers along a 20-mile stretch from Ormond Beach to New Smyrna Beach.

Beach officials identified two species as the culprits - moon and cannonball jellyfish - but say moon jellyfish are likely to be the main culprits.
‘The cannonball jellyfish is not really a stinging jellyfish,’ Marris said.
‘It's really not a seasonal thing. They are just at the mercy of the wind and current, so they can show up any time of the year.’

The warning came in a report into ocean acidification – an often overlooked side effect of burning fossil fuel.
Studies have shown that higher levels of carbon dioxide in the atmosphere doesn’t just trigger climate change but can make the oceans more acid.
Since the start of the industrial revolution, acidity levels of the oceans have gone up 30 per cent, marine biologists say.
The report, published in December 2010 by the UN Environment Programme, warns that the acidification of oceans makes it harder for coral reefs and shellfish to form skeletons – threatening larger creatures that depend on them for food.
The decline in creatures with shells could trigger an explosion in jellyfish populations.
The report, written by Dr Carol Turley of Plymouth University, said: ‘Ocean acidification has also been tentatively linked to increased jellyfish numbers and changes in fish abundance.’
Jellyfish are immune to the effects of acidification. As other species decline, jellyfish will move in to fill the ecological niche.
Populations have boomed in the Mediterranean in recent years. Some marine scientists say the changing chemistry of the sea is to blame.
