Our Pacific is Dying

What the video below, and Robertscribblers article, reveals is that our Pacific is dying. 

The scientists say they have “no idea” of why there has been a large die-off of sea lions and other creatures in the North Pacific. Generally, the pattern is to underestimate the scale of the problem and to see each problem as something isolated and unrelated to anything else.

Thankfully, there are people who do make a sincere effort to tell the truth. However, some of the strongest voices revealing the extent of the Fukushima catastrophe are the most terrible climate change deniers.

Some of the people who are telling us about climate change (lite) – usually liberals – completely ignore Fukushima and pretend it doesn’t exist.

This is all reductionist thinking (which pervades western and ‘scientific’ thought) run rampant.

The truth is that the Pacific is being killed by radiation continually flowing into the Pacific. This die-off is 3 years old and there has been no el-Ninos in that time.

But I’ve got some other news. Read Robertscribbler's article, look at the temperature anomoly maps and you will see that the Pacific is way warmer than ‘normal’ and is storing heat from the effects of anthropogenic global warming.

We have acidification of the ocean, massive plastic pollution, overfishing and ….(what have I left out)?

If you are looking for a single cause for the rapid death ot the Pacific then you could put it down to one – human overshoot and the catastrophic effects of ‘infinite growth’ in a world carrying 7+ billion human beings.

I commend the video below, but ask that people look at what is being revealed in the context of all the evidence.

Watch and mourn for all the wonderful biodivesity of our once wondrous Pacific Ocean

Starving Sea Lion Pups and Liquified Starfish — How We’ve Turned the Eastern Pacific into A Death Trap for Marine Species

Robertscribbler,

27 February, 2015

As of late January, the news reports were coming in hot and heavy. Baby sea lions were dying in droves. More than 15,000 of the pups were already lost due to starvation. And with each passing week, more than 100 of the emaciated, beleaguered, hopeless animals were washing up on California shores.

The pups staggered across beaches, wandered into vacant lots, or tottered, disoriented, along roadways. Refugees all to some unspeakable disaster. Orphans lost or abandoned by parents unable to provide them with even the most basic of sustenance.

Marine rescue centers, volunteer centers, and even animal shelters were inundated by a flood of desperate, dying animals. Their organs were shutting down. They could barely breathe or walk. The future generation of the more than 300,000 sea lions living along the US West Coast taking a severe blow from a deadly killer lurking in West Coast waters.

By late February more than 1000 sea lion pups had flooded the California Marine Mammal Center. Hundreds more found their way into local and ad-hoc shelters. The number was so great that all support systems for the animals were overwhelmed. Persons finding and seeking help for the dying pups were, more often than not, turned away due to lack of support and rescue resources.

It was like the scene out of some heart-wrenching sci-fi disaster movie. And everyone kept asking the same question — what could cause this?

Mass Sea Lion Deaths for Three Years Running

This most recent spate of sea lion pup deaths and strandings comes after years of the same. News media currently reports the event in isolation — as if 2015 were the only year for such a thing to happen. But the truth is that this crisis has been ongoing now since at least 2013, with an earlier episode in 2009-2010 preceding the current chain of related events.

The 2013 event was so severe that in the end 70 percent of the 50,000 sea lion pups born that year had died. The 2014 event was rather less severe, accounting for ‘only’ twice the normal loss rate. But 2015 has so far been so deadly that even 2013’s staggering number of sea lion pup losses could be exceeded.

The multi-year event represents such a heavy blow to sea lions that marine organizations have declared the entire current young generation under threat of being wiped out.

Adult Sea Lions, Otters, Starfish, Birds and other Marine Creatures Involved

But the story doesn’t stop at young sea lion deaths alone. From May through August of last summer, reports were flooding in of mass adult sea lion, otter, and bird deaths due to what appeared to be exposure to some form of toxin.

The animals would wash up on the beach or drop out of the sky. They would show signs of convulsions. Autopsies of the deceased animals revealed shrunken hippocampus, brain and heart lesions.

The same marine mammal center that is now taking in over 1,000 baby sea lion pups this summer took in 751 adults suffering from these signs of toxic poisoning. Simply put, the adults died this past summer and now the pups are starving.

Further down the food chain, creatures living in bottom water zones were also suffering and dying. Fishermen off Oregon had to go further and further afield to fill nets. Near shore fishing lines came up empty except for crabs scurrying up the lines as if in an attempt to escape from danger below.

And in 2013, thousands upon thousands of starfish began to turn to white clumps. A freakish instance of mass star fish death that continued inexorably through 2015.

The star fish would succumb to a strange wasting illness. An illness that would ultimately waste whole swaths of multiple starfish species (20 separate starfish species and millions of animals are now thought to be involved). Entire regions saw their starfish populations dwindle to zero. As with the mass sea lion deaths, marine researchers were both stunned and befuddled.

Perhaps even more disturbing is that the various species deaths just keep on coming — with no apparent end in sight.

A Hothouse Serial Killer

Just off shore, a warm wind runs from south to north over the increasingly wasted waters. Warm airs born of warm waters, providing us with clues for the cause of this ongoing mass death event. For the seas off the US West Coast have reached record levels of warmth — a level of ocean surface heat that flared with the most recent El Nino in 2009 and 2010. A warming that has been building steadily ever since mortality events began their incessant march in 2013.

Such widespread surface warming contributes to numerous detrimental changes to ocean health. Image source: Earth Nullschool. Data Source: Global Forecast System Model.)

Now a broad swath of surface water ranging from 2-5 C above average blankets an entire oceanic zone from Alaska to Mexico.

Such excess heat may seem innocuous at first blush. A little extra warm water may seem pleasant to the casual observer. But what seems pleasant actually conceals a deadly threat.

Warm surface waters spreading over the ocean can serve as a kind of lid. The warm water prevents cooler water from upwelling toward the surface, mixing nutrients and refreshing the water’s oxygen levels. This shut down of overturning is a dangerous oceanic condition called stratification. And it can level a severe blow to almost all creatures along the marine food chain. Plankton become less productive. Low oxygen zones expand, killing the slow-moving bottom creatures all while driving the mobile fish to more productive waters. In the warmer waters, toxic algae blooms become more prevalent. Harmful microbes, which are culled during influxes of cold water, thrive and multiply, posing a disease threat to all marine species. Finally, in the deeper reaches off the coasts of Washington and Oregon, the already oxygen-poor zones, zones rife with methane from hydrate venting, begin producing a deadly seep of hydrogen sulfide gas.

The living sea has now become a killer. And all it took was a little extra added heat to lock west coast waters in an expanding zone of warm water and low oxygen marine mortality.

For reference, high oxygen is shown in greens, blues and purples, low oxygen shown in oranges, reds and black. Image source: AMOP’s Study of Oxygen Minimum Zones. Image date: 2013.)

As a result we have the proliferation of the sea star wasting illness. An illness that would usually be contained by the seasonal influx of cooler waters. So too do we have instances of sea lion adults consuming fish, mullusks, and shellfish contaminated with domoic acid — a toxin produced by algae blooms in warm waters. And lastly, we have the overall stress on the food chain due to low oxygen and productivity which has driven sea lion food sources so far off shore that females are too exhausted after hunting to feed their pups.

More Dangers to Come

The recent mortality events mirror ocean warming episodes which caused similar die-offs at the end of glacial periods. Then, as now, warming robbed waters of oxygen and productive mixing, causing stress to numerous species.

However, the current pace of human warming is much more rapid than the warming periods that occurred at the ends of the ice ages. In addition, under business as usual human carbon emissions, the deadly, low-oxygen ocean zones are expected to expand, eventually covering the majority of the world ocean system. It’s a transition to a stratified ocean that will make the current west-coast die-off look like a minor prelude by comparison.

(Hydrogen sulfide eruption off Namibian coast on February 15, 2015. In Namibia, anoxic bottom waters host hydrogen sulfide producing bacteria. Runoff rich with organic material feeds these bacteria as they produce more toxic hydrogen sulfide gas. During upwelling events, the hydrogen sulfide is brought to the surface where it is visible as a florescent green or black slick. Under stratified and Canfield Oceans, more and more regions are capable of supporting deadly hydrogen sulfide production. Currently, the Baltic Sea, Offshore Namibia, the Chesapeake Bay, and Offshore Oregon are known to host broad regions of hydrogen sulfide producing bacteria in anoxic dead zones. Only in Nambia do these zones occasionally reach the surface waters, so far. Image source: Earth Observatory/NASA.)

Eventually, if CO2e levels exceed 800-1000 parts per million, a transition to an even more deadly state called a Canfield Ocean is increasingly likely. And a Canfield Ocean is a powerful killing machine. Implicated all the previous hothouse extinctions, this killer, during the Permian Extinction, was likely primarily responsible for the deaths of 95 percent of species in the ocean and 70 percent of species on land. For the oceans eventually filled up with deadly toxins (primarily in the form of hydrogen sulfide gas) which then vented into the atmosphere.

It’s a very deadly ocean state we want to avoid at all costs. And we should view these very troubling instances of ocean species mortality along the North American West Coast as a warning to stop warming to oceans as swiftly as possible.

Fukushima Fallout WORLDWIDE

The Tibetan Plateau is registering more radiation than during the nuclear bomb test in the 1960's.

Fish testing at 124 times over radiation limit caught off Fukushima

Fish with deadly levels of radioactive cesium have been caught just off the coast of Fukushima prefecture, as scientists continue to assess the damage caused to the marine food chain by the 2011 nuclear disaster.

RT,

15 January, 2015

One of the samples of the 37 black sea bream specimens caught some 37 kilometers south of the crippled power plant tested at 12,400 becquerels per kilogram of radioactive cesium, making it 124 times deadlier than the threshold considered safe for human consumption, Japan's Fisheries Research Agency announced.

The samples were caught at the mouth of the Niidagawa river in Iwaki, Fukushima Prefecture, on November 17. Two other fish caught there also tested non-safe for human consumption, showing radiations levels of 426 and 197 becquerels per kilogram. The rest of the fish were reportedly within safety limits.

Black sea bream are currently restricted from being fished in Miyagi and Fukushima prefectures and sold for human consumption, as scientists from the Fisheries Research Agency say they plan to investigate the source of the contamination further.

After the Fukushima disaster, Japan lowered its threshold for cesium levels in food from 500 becquerels per kg to 100 becquerels per kilo, making the country’s regulations six times stricter than European Union standards. The record cesium reading was recorded last year when a fish caught near the plant carried 740,000 becquerels of cesium per kilogram.

Professor Chris Busby from the Scientific Secretary of the European Committee on Radiation Risk and a member of the UK Department of Health Committee Examining Radiation Risk for Internal Emitters (CERRIE), says that despite a high level of radiation in the marine food chain, Japan so far is the only one dealing with a direct threat.

“The concentrations of radionuclides, which are going to the Pacific or have been injected to the Pacific, by the time they get to the US, and to China and to South East Korea and so on will not be enormously high,” Busby told Voice of Russia.

Yet the scientist warned that nuclear contamination of Japan could result in 400-800 extra cancer cases in Japan in the next fifty years.

“We've already seen some effects in infant mortality and thyroid cancer in Japan,” Busby said. “So I think this is just going to get worse. I think we are going to see a major effect on the general health of the Japanese population in Northern Japan. There's going to be a decrease in the birth rate and an increase in the death rate.”

In the meantime, TEPCO, the operator of the Fukushima nuclear site, reported radiation levels 8 times government safety guidelines. TEPCO told press that the predominant reason behind the sharp increase in radiation at the plant was X-rays coming from storage tanks holding radioactive water that has been leaking from the Fukushima facility.
