Research finds higher ocean acidification off Alaska that could threaten fishing industry

Hmm. Maybe part of the reason the salmon run was missing?

AGW crisis peddlers think the ocean is like their stagnant bathtubs. They sit around splashing with the rubber duck and repeat the AGW authorized shtick - "ocean acidification"
I like photo: the acedemiacs and students singing the crisis song. Wouldn't have anything to do with political correctness and funding would it?
Hey! check it out, there is this really cool new thing called currents.
NOTICE THEY SPECULATE - COLDER - WATERS... NOT "GLOBAL WARMING" WARMER WATERS.
Alaskan fisheries biologists believe that salmon populations throughout the Gulf of Alaska have been withering due to the shifting of currents in the Pacific Ocean.
The Pacific decadal oscillation (PDO) may be what is causing waters to cool within the Alaskan Gulf. King salmon stocks have been tapering there from coast to coast for the past two years, Anchorage Daily News reports.
There have been historical indications that such geographically widespread weaknesses are connected to PDOs that cause the Gulf to suck in
Kodiak Island, Susitna Valley and the Kenai Peninsula are also experiencing changes in water temperatures and a consequent descend in king salmon catches. Take the king salmon yields in the Susitna Valley’s Deshka River, which fell from an average annual 60,000 fish to under 8,000 last year United Press International reports.
This year is showing further dwindling: declining catches have led to forced closures at Kodiak, Kenai, Susitna and Copper River. And in regions without closures, catches are low, with sonar counters showing about 50 per cent the amount of big fish there ought to be.
Due to the widespread tapering from Kodiak Island through Stikine River in Southeast Alaska, fisheries biologists guess things first went wrong in the open sea. But they have no solid answers.
Although they speculate that
the colder waters have caused this shift,
details remain unknown.
It is possible that
have thwarted plankton productivity, thereby altering the food chain and possibly leading to the starvation of young fish. Or perhaps the different climate is more hospitable to the predators who feed on them.
"The runs are looking pretty poor,'' said Keith Pahlke, a researcher with the state department, regarding the Susitna Valley’s Deshka River harvest. "The managers are stressing out over this. We thought we knew what we were doing here. It's pretty perplexing."

What do you call someone who 'invents' the other sides arguments and then picks them apart, having designed them as feeble and stupid?
Yup. A strawman...
Add to that a dollop of whining smog (smoke and fog with no substance )
So regional cooling due to 'climate change' is relevant to global warming? We EXPECT to see changes in climate from the warming which if you look on a GLOBAL level is continuing just as expected.
And loss of the salmon stocks is just one 'price' we pay for inaction and allowing 'free speech' to degenerate to mob action ( aka trolling ).

JRS.. you sound quite foolish
ANCHORAGE - Erosion threatens to topple coastal Alaska villages. Melting ice threatens polar bears. Now, a marine scientist says the state's marine waters are turning acidic from absorbing greenhouse gases faster than tropical waters, potentially endangering Alaska's $4.6 billion fishing industry.
The same things that make Alaska's marine waters among the most productive in the world - cold, shallow depths and abundant marine life - make them the most vulnerable to acidification, said Jeremy Mathis, a chemical oceanographer at the University of Alaska Fairbanks.
"Ecosystems in Alaska are going to take a hit from ocean acidification," he said. "Right now, we don't know how they are going to respond."
Alaska has already seen more than its share of global warming effects: shrinking glaciers, coastal erosion, the march north of destructive forest beetles formerly held in check by cold winters, melting Arctic Ocean ice that also threatens walrus and other marine mammals.
Ocean acidification, the lowering of basicity and the increase in acidity of marine waters, is tied to increased carbon dioxide levels in the atmosphere.

Erosion is caused by global warming? Why not blame gravity and percipitation, they are a more direct influence. Erosion wasn't happening before man started using fossil fuel?
You and your crazy climate Eden, all we need do is sacrifice our economy and a perfect climaate world awaits. You wouldn't have any experimental tests of this crazy fantasy, would you?
