This is another item coming in from the global warming enthusiast and againwe are attempting to take a giant leap of inference that is not based on anyconvincing work at all. Note the commentfrom Marc Morano at the end.
What has been taking over the oceans is a deadly predator that has knockedout most of the top of the food chain allowing the lower orders like jelly fishto prosper. Establishing proper harvestmanagement globally will completely reverse this.
As mentioned, the ocean is not now acidic nor do I think it has ever been. There is just too much limestone (calciumcarbonate and magnesium sulphate) and its like available.
Jellyfish are taking over theoceans: Population surge as rising acidity of world's seas kills predators

Britain's beaches could soon be inundated withrecords numbers of jellyfish, marine experts warned today.
Scientists say the number of jellyfish are on therise thanks to the increasing acidity of the world’s oceans.
The warning comes in a new report into oceanacidification – an often overlooked side effect of burning fossil fuel.
Studies have shown that higher levels of carbondioxide in the atmosphere doesn’t just trigger climate change but can make theoceans more acid.

Since the start of the industrial revolution,acidity levels of the oceans have gone up 30 per cent, marine biologists say.
The new report, published by the UN EnvironmentProgramme during the Climate Change talks in Cancun, Mexico, warns that theacidification of oceans makes it harder for coral reefs and shellfish to formskeletons – threatening larger creatures that depend on them for food.
The decline in creatures with shells could triggeran explosion in jellyfish populations.
The report, written by Dr Carol Turley of Plymouth University
Jellyfish are immune to the effects ofacidification. As other species decline, jellyfish will move in to fill theecological niche.
Populations have boomed in the Mediterranean in recent years. Some marine scientists say the changing chemistry of the seais to blame.
Studies have shown that clown fish – the speciesmade famous by the movie Finding Nemo – find it harder to navigate through moreacidic waters.

They are also less likely to avoid predators, andmay activity seek them out, scientists have shown.
Test on laboratory fish have found that moreacidic water rewires their brains, turning them into fish with a death wish.
The report says acidification may pushoverstressed oceans into disaster with far reaching consequences the billionsof people who rely on fish as their main protein source.
The effects of extra carbon dioxide may be greaterin colder waters such as the North Sea and north Atlantic ,the report says.
The damage to corals and shellfish could affectthe whole food chain – hitting species such as salmon which feed on smallershell building animals.
‘The basic chemistry of sea water is being alteredon a scale unseen within fossil records over at least 20 million years,’ thereport said.
Oceans are naturally alkaline – and had a pH levelof about 8.2 in 1750. Since the industrial revolution, the acidity hasincreased by 30 per cent.
As more carbon dioxide enters the oceans itproduces carbonic acid.
As the acid breaks down it makes sea water lessalkaline and more acidic.
‘If we continue at this rate, the ocean pHwill decline by a further 0.3 by the end of this century, an unprecedented 150per cent increase in ocean acidity,’ the report states.
‘This rate of change has not been experienced foraround 65 million years, since the dinosaurs became extinct.’
Achim Steiner, UNEP executive director, said:‘Ocean acidification is yet another red flag being raised, carrying planetaryhealth warnings about the uncontrolled growth in greenhouse gas emissions.
‘It is a new an emerging piece in the scientificjigsaw puzzle, but one that is triggering raising concern.’

The oceans are alkaline, not acid. The 30% number issomething they pulled out of their posteriors. Corals and shellfish evolvedwhen atmospheric CO2 levels were 10-20X higher than today. It is beyondludicrous to claim that CO2 is reducing their ability to form shells. Thechemical properties of Aragonite have not changed.
These people are determined to take control of worldgovernance no matter how many lies they have to tell.
