The cruel and lonely death of an American nuclear weapons scientist
And if you’re a believer that violent ends produce restless spirits, the Presidio is full up with phantoms as a result.
The most haunted place is said to be Letterman Army Hospital, once the base’s largest medical facility
In looking for Presidio ghost stories, though, we stumbled across a far stranger tale than any haunting: the real-life demise of a nuclear scientist — a chapter of the Cold War, as far as we can tell, untold since 1953.
The brain tumor presented a particular problem for the Atomic Energy Commission: It had the potential to cause erratic behavior and uncontrolled verbal outbursts. They were fearful that as he lost control of his mental faculties, Twitchell would begin spilling nuclear secrets. He knew “as much about atomic energy as any one man,” an anonymous source in the commission would later tell the Oakland Tribune.
So they built a secret ward just for Twitchell. At the cost of $100,000 — nearly $1 million today — construction began at the Letterman Army Hospital in San Francisco’s Presidio for the unusual patient. Once finished, all doctors and nurses who might interact with Twitchell were given rigorous screenings for any national security issues. In the end, only one male nurse was trusted to primarily care for Twitchell. A guard stood watch outside the room at all times.
Unbeknownst to the other military patients at the hospital, a civilian lay dying in his own wing. “He was the hospital’s hush-hush case,” the San Francisco Examiner reported.
An anonymous source told the Tribune this was standard protocol to keep scientists from blabbing while “unbalanced, anesthetized or under the influence of dentists’ ‘laughing gas.'” Although expensive, it was the only way to maintain national security.
Hitler’s quest for nuclear weapons
WW2: Hitler’s true nuclear capacity exposed in secret sabotage mission that ‘saved world’
WORLD WAR 2 saw the Allies cooperate to fight Adolf Hitler’s Nazi Germany but jaw-dropping documents reveal just how close he came to using nuclear weapons. Express UK By CALLUM HOARE Oct 21, 2020 The German nuclear weapons programme was an unsuccessful scientific effort to research and develop atomic weapons during World War 2. It went through several phases but was ultimately “frozen at the laboratory level” with historians and scholars alike generally agreeing it failed on all fronts. With that, Hitler is thought to have focused more on his revolutionary V1 and V2 rockets, but he came terrifyingly close to arming them with nuclear warheads, according to declassified papers unearthed by writer and filmmaker Damien Lewis.
“The greatest fear was that the Nazis had mastered the technology to fit a nuclear or radiological charge to the V2s, in which case there would be no defence possible.
“Churchill ordered aerial surveys to forewarn of such attacks – dry-run rehearsals to prepare for such an ordeal, and for frontline doctors to be briefed on the symptoms of radiation poisoning.
Such fears were very real. Following German physicist Otto Hahn splitting the atom in December 1938, the Allies believed the Germans to be two years ahead in the race to build the atom bomb.”
In May 1940, German forces struck a further blow in the race for nuclear supremacy after seizing Olen, Belgium, where the largest remaining stock of European uranium was located.
British intelligence reports on Operation Peppermint found by Mr Lewis revealed fears from London.
One read: “Since the fall of Belgium, much of the largest stock of uranium has been available [to Germany] from the refinery.”
According to Mr Lewis, its destination was the AuerGesellschaft refinery, at Oranienburg, Germany.
Allied research suggested it would require 20,000 workers, half a million watts of electricity and $150million (£114million) in expenditure to build the world’s first atom bomb.
Hitler, who now controlled most of western Europe, could demand such resources.
And, in concentration camps, he had access to millions of workers.

A history of nuclear weapons accidents
In early 2009, two nuclear submarines, the French Le Triomphant and British Vanguard, both carrying nuclear weapons, crashed into each other deep in the Atlantic. Fortunately, they were not going fast enough to cause much damage.
Two years earlier, the American Air Force lost six nuclear armed cruise missiles for 36 hours when, unknown to anyone, they were fitted to a B-52 bomber and flown completely unauthorised to a base in Louisiana, left unguarded on the runway until anyone worked out what had happened.
In 2000, the Danish newspaper Jyllands-Posten reported that classified documents obtained by a group of former workers at the Thule airbase suggest that one of four hydrogen bombs on a B-52 bomber that crashed there in 1968 was never found.
There are many instances of false alarms and nuclear bombs nearly being launched. One of the most dangerous of these was stopped by little-known hero Lieutenant Colonel Petrov who, in 1983, probably really did save the world. When he was alerted by an early warning system that five nuclear missiles by America were coming towards the Soviet Union, instead of immediately raising the alarm to his superiors who would have ordered retaliation, he instinctively decided that, if there was an attack, more than five missiles would have been launched and rightly decided that the system was faulty.
These incidents seem to have done nothing to dent the UK and America’s insistence that nuclear weapons safeguard and guarantee peace. The old Cold War politics of nuclear deterrents can seemingly do nothing to deter democratic interference on social media or the global impact of COVID-19. Like scary but lumbering dinosaurs, our trident submarines roam the ocean’s depths with enormous fire power – just one missile can kill more than 10 million people – while Russian President Vladimir Putin interferes with democratic elections in the West for less than the price of a non-nuclear fighter jet.https://bylinetimes.com/2020/10/21/the-nuclear-treaty-dividing-the-world/
Small modular nuclear reactors create intensely radioactive wastes
A bridge to nowhere New Brunswick must reject small modular reactors, Beyond Nuclear International, By Gordon Edwards and Susan O’Donnell, 12 Oct, 20 ”……… In New Brunswick, the proposed new reactors (so-called “small modular nuclear reactors” or SMNRs) will create irradiated fuel even more intensely radioactive per kilogram than waste currently stored at NB Power’s Point Lepreau Nuclear Generating Station. The non-fuel radioactive wastes will remain the responsibility of the government of New Brunswick, likely requiring the siting of a permanent radioactive waste repository somewhere in the province.
Interestingly, promoters of both new nuclear projects in New Brunswick – the ARC-100 reactor and the Moltex “Stable Salt Reactor” – claim their reactors will “burn up” these radioactive waste fuel bundles. They have even suggested that their prototype reactors offer a “solution” to Lepreau’s existing nuclear fuel waste problem. This is untrue. Radioactive left-over used fuel from the new reactors will still require safe storage for hundreds of thousands of years.
……… Until now, every effort to recycle and “burn up” used reactor fuel – in France, the UK, Russia and the US – has resulted in countless incidents of radioactive contamination of the local environment. In addition, none of these projects eliminated the need for permanent storage of the left-over long-lived radioactive byproducts, many of which cannot be “burned up.”…….
The nuclear waste problem is not going away. The recent letter from more than 100 groups across Canada, and the recent cancellation of the proposed nuclear waste dump in Ontario have shown that significant opposition to new nuclear energy generation exists. Because producing nuclear energy always means producing nuclear waste as well……. https://beyondnuclearinternational.org/2020/10/12/a-bridge-to-nowhere/,
14 million tonnes of plastic on ocean floor – more on the coasts
Every drink bottle we buy, face scrub we use and chip packet we finish results in tiny plastics entering the ocean.But where are these tiny micro-plastics, exactly?
Are they floating around on the ocean’s surface, waiting to be scooped up by a surfer?
Or are they stuck in the tummies of turtles or seabirds?
A new study by the CSIRO, Australia’s national science agency, has estimated up to 14 million tonnes of micro-plastics have sunk to the bottom of the ocean floor.
The peer-reviewed research, published on Tuesday, is the first global estimate for micro-plastics on the seafloor. Dr Britta Denise Hardesty, team leader with CSIRO’s Oceans and Atmosphere, said 14 million tonnes of micro-plastics was a “huge amount, especially when you think about how tiny all those bits are”.Dr Britta Denise Hardesty, team leader with CSIRO’s Oceans and Atmosphere, said 14 million tonnes of micro-plastics was a “huge amount, especially when you think about how tiny all those bits are”.

The peer-reviewed research, published on Tuesday, is the first global estimate for micro-plastics on the seafloor.
Dr Britta Denise Hardesty, team leader with CSIRO’s Oceans and Atmosphere, said 14 million tonnes of micro-plastics was a “huge amount, especially when you think about how tiny all those bits are”.
To put it into perspective: Imagine five carrier bags stuffed with plastic dotted along every single metre of coastline around the world, excluding Antarctica
The piles of bags would sit on every Australian beach, along Italy’s Amalfi Coast, around Vietnam’s Ha Long Bay, and all around Canada’s coastlines and beyond.
Now imagine someone pushing those bags into the ocean, and letting them sink into the darkness.
“It’s a confronting amount, and hopefully it provides a reasonable wake-up call,” Dr Hardesty told The New Daily.
“We’re finding them hundreds of kilometres offshore and thousands of metres deep – more micro-plastics than has been found by lots of other studies.”
“Micro-plastics come from the same place as plastics,” Dr Hardesty said, adding “micro just means they’re smaller than 5mm”.
“It’s really just small plastic from single-use items, consumer goods, industry or fishing-related goods, cosmetics, micro-beads, agriculture, aquaculture, household waste, everything.”Many of these tiny plastics end up in our oceans via stormwater drains, sewage systems, sea-based activities, littering, things falling off the backs of trucks, and improper waste management where people intentionally dump rubbish straight into the sea or rivers.
They often end up in the stomachs of marine animals like dolphins or fish, while bigger pieces of plastic can be just as dangerous.
“Masks that have those little straps can tangle the feet and legs of sea birds and things like that,” Dr Hardesty said.
“Rubber gloves might be more likely to look like a jellyfish that could be mistakenly eaten by turtles if they end up in the ocean.”
The World Economic Forum estimates one garbage truck of plastic alone is dumped into the ocean every minute of every day.
It estimates there could be more plastic in the ocean than fish by 2050.
The missing piece
Although the CSIRO’s findings are troubling, perhaps what’s more concerning is the answer to the following question: Where is the rest of the missing plastic?
Compared to the tonnes of plastic entering the ocean every day, Dr Hardesty said 14 million tonnes on the ocean floor was “just a drop in the ocean”.
“Where is all the missing plastic? Is it in the stomachs of animals? Is it floating on the surface?” she said.
“I’d say most of it is on our coastlines.”
Daunting task of removal of Russia’s spent nuclear fuel rods from Andreeva Bay
One-third of all nuclear waste removed from Cold War dump site https://thebarentsobserver.com/en/nuclear-safety/2020/10/one-third-all-nuclear-waste-removed-cold-war-dump-site
Another 12 special design casks with spent nuclear fuel from Cold War submarines are soon to be shipped out of Andreeva Bay on Russia’s Arctic Barents Sea coast. ByThomas Nilsen October 02, 2020
About 35% of the 21,000 spent uranium fuel elements originally stored in three rundown tanks is so far lifted out, repacked and sent to Russia’s reprocessing plant at Mayak in the South-Urals, informs Aleksandr Krasnoshchekov, director of the SevRAO’s branch in Andreeva Bay. SevRAO is the federal enterprise for handling radioactive waste in the northwestern region.
The company has a staff of 100 in Andreeva Bay in the Litsa fjord, a closed-for-civilians fjord near the border to Norway where the Northern Fleet has two basing points for nuclear submarines.
Here, the navy started to store casks with highly radioactive spent uranium fuel from its first nuclear-powered in the 1960s. First in rusty containers outdoor, later in a pool-building that broke down. In the 1980s, the elements were moved over to three concrete tanks in very poor conditions.
After nearly 20 years of improving the infrastructure, securing the site from leakages and building a new crane at the port, the first shipment with nuclear waste left Andreeva Bay in 2017.
Neighboring Norway has spent more than €30 million to support the cleanup of the nuclear dump located only about 50 km from its border.
Also Sweden, Great Britain, Italy and the European Commission have contributed. Italy, as an example, paid for building the “Rossita”, a special purpose ship sailing in shuttle from Andreeva Bay to Atomflot in Murmansk where the containers are reloaded to rail wagons. According to director Krasnoshchekov, the ongoing work is done based on contracts with these countries, he says in an interview with Vesti Murman.
Most of the work done so far concerns the elements easy to lift out.
Way more challenging times are ahead, as the damaged elements in the third tank, 3A, are to be secured and lifted out.
Take a closer look at the photo below to understand the scoop of the challenge. Some of these rusty, partly destroyed steel pipes contain fuel rods where the uranium will fall out if lifted straight up.
The work on tank 3A is scheduled to start in 2023, after tank 2A and 2B is completed. The experts are don’t want to start the most risky work before as much as possible of the other waste elements are removed. A criticality accident in Andreeva Bay is worst-case scenario.
As previously reported by The Barents Observer, the total radionuclide inventory in the three tanks is estimated to be equal to the remains of Rector No. 4 inside the Chernobyl sarcophagus in Ukraine. This according to a study by the British nuclear engineering company Nuvia.
The original 22,000 spent fuel elements dumped in Andreeva Bay are coming from 90-100 reactor cores powering the Soviet Union’s Cold War submarines sailing out from the naval bases along the coast of the Kola Peninsula from the late 1950s to 1982.
The first reactor cores of the November class submarines were reloaded in the early 1960s.
Additional to the spent fuel elements, some 10,000 cubic meters of solid radioactive waste from Andreeva Bay are shipped to the regional handling and storage facility in Saida Bay, a few hours sailing to the east on the Kola Peninsula. Huge piles of solid radioactive waste were stored outdoor summer and winter in the same area. Now, a building is erected to protect the boxes from rain and snow, before being repacked and shipped to the Saida Bay.
Ionising radiation – the tragedy of the ”radium girls”.
They weren’t just making paints, they were doing the painting, too. According to NPR, US Radium hired scores of girls and young women — as young as just 11-years-old — to paint watch dials with the glow-in-the-dark, radium-based paint. As if just working with the paint wasn’t bad enough, they were also encouraged to put the brush between their lips and twirl it into a point. It was the best way to get truly precise numbers and brush strokes, but with each lick of the brush, they were swallowing radium.
the human body isn’t great at telling the difference between radium and calcium. Radium gets absorbed into the bones just like calcium does, and when that happens, the rot starts.
Writer and historian Kate Moore documented the cases of the Radium Girls (via The Spectator) and found that there were a whole host of symptoms. Some started suffering from chronic exhaustion. For many, it started with their teeth — one by one, those teeth would start to decay and rot. When they were removed, their gums wouldn’t heal. In some cases, the jaw would just simply disintegrate at the dentist’s touch. Bad breath was common. Skin became so delicate that the slightest touch would tear open wounds. Ulcers formed for some, and those that were pregnant bore stillborn babies.
THE RADIUM GIRLS HAD TO BE BURIED IN LEAD-LINED COFFINS
The Radium Girls weren’t just sick, they were very literally radioactive. Mollie Maggia was exhumed in 1927, in the hopes that her bones would give still-living Radium Girls the evidence they needed to win in court. According to Popular Science, her coffin was lifted out of the ground, and her body? It glowed. That wasn’t entirely surprising, considering her bones were found to be highly radioactive — and considering radium’s half-life is 1,600 years, they’re not going to stop glowing any time soon.
Eventually, 16 separate sites around Ottawa would be classified as Superfund sites.
NPR Illinois says that many have been cleaned up, but as of 2018, there was at least one site — a 17-acre plot of land on the Fox River — that still remained a highly radioactive and terrifying legacy of the Radium Girls.
THE MESSED UP TRUTH ABOUT THE RADIUM GIRLS https://www.grunge.com/181092/the-messed-up-truth-about-the-radium-girls/ BY DEBRA KELLY/DEC. JULY 14, 2020
History is filled with episodes that prove mankind is just sort of making everything up as it goes. There’s no shortage of things that can kill us or do horrible, terrible things to our soft and squishy bodies, and every time we think we know about them all, it turns out there’s something else lurking around the corner.
And sometimes, it’s disguised as something awesome. Need proof? Look no further than the Radium Girls.
Yes, that radium. Today, the Royal Society of Chemistry says there’s really only one use for radium — targeted cancer treatments, because it’s so good at killing cells. It was first discovered in 1898 by Marie and Pierre Curie, after they extracted a single milligram from ten tons of a uranium ore called pitchblende. And it was pretty darn cool. It glowed, and seriously, how exciting is that? Unfortunately, it was also deadly — as the so-called Radium Girls would find out.
Nano diamond batteries from nuclear waste? Impractical and not likely to ever happen
Arkenlight “surprised” by NDB’s grand nuclear diamond battery claims, New Atlas By Loz Blain, September 30, 2020 Totally safe, self-charging batteries that generate power for thousands of years … It’s an exciting thought, and when we wrote about California’s NDB in August, the story generated all kinds of feedback. A lot of people felt some of NDB’s claims were outrageously false, contravening the laws of physics and vastly overstating the capabilities of a device that was already well understood.
IWe ended up having a very informative chat with Morgan Boardman, an Industrial Fellow and Strategic Advisory Consultant with the Aspire Diamond Group at the South West Nuclear Hub of the University of Bristol.
He is also – and this is much less of a tongue twister – the CEO of a new company called Arkenlight, which has been created to commercialize the Bristol team’s diamond battery technologies, among other radioisotope-driven power sources.
In short, Boardman broadly agreed with the position that these “betabatteries” produce power far too slowly to replace the cells in your iPhone or Tesla; yes, you could build a betabattery for a phone or a vehicle, but only if you’re prepared to have the battery be several times the size of the device it’s powering.
What’s more, he pointed out that the University of Bristol took out patents covering all devices that embed radioisotopes in diamond structures, and that Arkenlight now holds those patents. So if NDB is talking about using the same kind of nuclear diamond technology – which it sure sounds like it is – it could have some licensing issues ahead of it.
So it seems it’s time to pump the brakes on some of NDB’s more exciting claims ……….. https://newatlas.com/energy/arkenlight-nuclear-diamond-batteries/
Dr Helen Caldicott busts the media spin on ‘small nuclear reactors’
HELEN CALDICOTT: Small modular reactors — the next big thing?
https://independentaustralia.net/environment/environment-display/helen-caldicott-small-modular-reactors–the-next-big-thing,14342#disqus_thread By Helen Caldicott | 27 September 2020 Politicians debating nuclear power as an energy source, know little of the facts that make small modular reactors a bad idea, writes Dr Caldicott. AUSTRALIAN politicians are contemplating developing nuclear power for this country. In their ignorance, they are mooting “small modular reactors” (SMRs) about which they clearly know little.
The so-called “nuclear renaissance” died following the Fukushima catastrophe when one-sixth of the world’s nuclear reactors closed. However, global nuclear corporations – Toshiba, NuScale, Babcock & Wilcox, GE Hitachi, General Atomics and the Tennessee Valley Authority – did not accept defeat.
Their new strategy has been to develop small modular nuclear reactors without the dangers inherent in large reactors — safety, cost, proliferation risks and radioactive waste. But these claims are fallacious for the reasons outlined below.
Basically, there are three types of SMRs which generate less than 300 megawatts of electricity compared with current day 1000 megawatt reactors.
Light water reactors designs
These will be smaller versions of present-day pressurized water reactors using water as the moderator and coolant, but with the same attendant problems as Fukushima and Three Mile Island. Built underground, they will be difficult to access in the event of an accident or malfunction.
Mass-produced (turnkey production) large numbers must be sold yearly to make a profit. This is an unlikely prospect because major markets – China and India – will not buy U.S. reactors when they can make their own.
If safety problems arise – as in General Motors cars – they all must be shut down which will interfere substantially with electricity supply.
SMRs will be expensive because the cost per unit capacity increases with a decrease in reactor size. Billions of dollars of government subsidies will be required because Wall Street is allergic to nuclear power. To alleviate costs, it is suggested that safety rules be relaxed, including reducing security requirements and a reduction in the 10-mile emergency planning zone to 1,000 feet.
Non-light water designs
These are high-temperature gas-cooled reactors (HTGR) or pebble bed reactors. Five billion tiny fuel kernels consisting of high-enriched uranium or plutonium will be encased in tennis-ball-sized graphite spheres which must be made without cracks or imperfections — or they could lead to an accident. A total of 450,000 such spheres will slowly and continuously be released from a fuel silo – passing through the reactor core – and then be re-circulated ten times. These reactors will be cooled by helium gas operating at very high temperatures (900 degrees Celsius).
A reactor complex consisting of four HTGR modules will be located underground, to be run by just two operators in a central control room. Claims are that HTGRs will be so safe that a containment building will be unnecessary and operators can even leave the site – “walk away safe” reactors.
However, should temperatures unexpectedly exceed 1,600 degrees Celsius, the carbon coating will release dangerous radioactive isotopes into the helium gas and at 2,000 degrees Celsius the carbon would ignite creating a fierce graphite Chernobyl-type fire.
If a crack develops in the piping or building, radioactive helium would escape and air would rush in, also igniting the graphite.
Although HTGRs produce small amounts of low-level waste they create larger volumes of high-level waste than conventional reactors.
Despite these obvious safety problems and despite the fact that South Africa has abandoned plans for HTGRs, the U.S. Department of Energy has unwisely chosen the HTGR as the “Next Generation Nuclear Plant”.
Liquid metal fast reactors (PRISM)
It is claimed by proponents that fast reactors will be safe, economically competitive, proliferation-resistant and sustainable.
They will be fueled by plutonium or highly enriched uranium and cooled by either liquid sodium or a lead-bismuth molten coolant. Liquid sodium burns or explodes when exposed to air or water and lead-bismuth is extremely corrosive producing very volatile radioactive elements when irradiated.
Should a crack occur in the reactor complex, liquid sodium would escape, burning or exploding. Without coolant, the plutonium fuel could reach critical mass, triggering a massive nuclear explosion scattering plutonium to the four winds. One-millionth of a gram of plutonium induces cancer and it lasts for 500,000 years. Extraordinarily, claims are made that fast reactors will be so safe they will require no emergency sirens and emergency planning zones can be decreased from ten miles to 1,300 feet.
There are two types of fast reactors: a simple plutonium fueled reactor and a “breeder” in which the plutonium reactor core is surrounded by a blanket of uranium 238 which captures neutrons and converts to plutonium.
The plutonium fuel, obtained from spent reactor fuel will be fissioned and converted to shorter-lived isotopes — caesium and strontium which last 600 years instead of 500,000. Called “transmutation”, the industry claims that this is an excellent way to get rid of plutonium waste. But this is fallacious because only ten per cent fissions, leaving 90 per cent of the plutonium for bomb-making etc.
Three small plutonium fast reactors will be grouped together to form a module and three of these modules will be buried underground. All nine reactors will then be connected to a fully automated central control room operated by only three operators. Potentially then, one operator could simultaneously face a catastrophic situation triggered by the loss of off-site power to one unit at full power, in another shut down for refuelling and in one in start-up mode. There are to be no emergency core cooling systems.
Fast reactors require a massive infrastructure including a reprocessing plant to dissolve radioactive waste fuel rods in nitric acid, chemically removing the plutonium and a fuel fabrication facility to create new fuel rods. A total of 10,160 kilos of plutonium is required to operate a fuel cycle at a fast reactor and just 2.5 kilos is fuel for a nuclear weapon.
Thus fast reactors and breeders will provide extraordinary long-term medical dangers and the perfect situation for nuclear weapons proliferation. Despite this, the industry is clearly trying to market them to many countries including, it seems, Australia.

Relicensing Turkey Point nuclear station – a striking example of a dangerous action in climate change times
With climate change, aging nuclear plants need closer scrutiny. Turkey Point shows why. https://thebulletin.org/2020/09/with-climate-change-aging-nuclear-plants-need-closer-scrutiny-turkey-point-shows-why/ By Caroline Reiser , September 14, 2020Last December, two nuclear reactors at Florida’s Turkey Point Nuclear Generating Station, located 25 miles south of Miami, became the first reactors in the world to receive regulatory approval to remain operational for up to 80 years, meaning reactors that first came online in the 1970s could keep running beyond 2050.
The ages of the Turkey Point reactors are not unusual; of the 95 reactors currently licensed to operate in the United States, only five are less than 30 years old, while more than half are 40 or more years old. The Turkey Point reactors are a bellwether, just the first of possibly many aging nuclear reactors that will seek permission to stay online well into the middle of the century. Not long after the December decision, in March 2020, the US Nuclear Regulatory Commission granted two more reactors, located in Pennsylvania, the same extensions that it gave Turkey Point.
In pursing these extensions, the US commercial nuclear industry and its supporters collide with the realities of the aging US nuclear fleet and climate science projections. Existing safety and environmental requirements fail to provide the oversight necessary to ensure communities and the environment are protected. As nuclear reactors receive permission to operate for twice as long as originally envisaged, and in a world that, because of climate change, is drastically different from the one they were built for, the insufficiency of the existing regulatory framework is daunting.
A 40-year lifespan? At the beginning of its commercial nuclear power program, the United States designed and licensed reactors with a 40-year projected lifetime. Once the 40-year license is set to expire, regulations require the reactor owner to apply for a renewed license in order to continue operating for an additional 20 years. What the regulations don’t make clear, however, is the number of times a reactor license can be renewed. What Turkey Point received last year was not its first, but its second extension—what regulators call a subsequent renewed license. Continue reading
Climate change and the loss of sea otters
Loss of sea otters accelerating the effects of climate change, New research published in Science reveals that the influence of a key predator governs the pace of climate impacts on Alaskan reefs EurekAlert, BIGELOW LABORATORY FOR OCEAN SCIENCES , 13 Sept 20, The impacts of predator loss and climate change are combining to devastate living reefs that have defined Alaskan kelp forests for centuries, according to new research published in Science.
“We discovered that massive limestone reefs built by algae underpin the Aleutian Islands’ kelp forest ecosystem,” said Douglas Rasher, a senior research scientist at Bigelow Laboratory for Ocean Sciences and the lead author of the study. “However, these long-lived reefs are now disappearing before our eyes, and we’re looking at a collapse likely on the order of decades rather than centuries.”
The coral-like reefs, built by the red alga Clathromorphum nereostratum, are being ground down by sea urchins. Sea urchins exploded in number after their predator, the Aleutian sea otter, became functionally extinct in the 1990’s. Without the urchins’ natural predator to keep them in check, urchins have transformed the seascape – first by mowing down the dense kelp forests, and now by turning their attention to the coralline algae that form the reef.
Clathromorphum produces a limestone skeleton that protects the organism from grazers and, over hundreds of years, forms a complex reef that nurtures a rich diversity of sea life. With kelp gone from the menu, urchins are now boring through the alga’s tough protective layer to eat the alga – a process that has become much easier due to climate change.
“Ocean warming and acidification are making it difficult for calcifying organisms to produce their shells, or in this case, the alga’s protective skeleton,” said Rasher, who led the international team of researchers that included coauthors Jim Estes from UC Santa Cruz and Bob Steneck from University of Maine. “This critical species has now become highly vulnerable to urchin grazing – right as urchin abundance is peaking. It’s a devasting combination.”………..
The results of the experiment confirmed that climate change has recently allowed urchins to breach the alga’s defenses, pushing this system beyond a critical tipping point.
“It’s well documented that humans are changing Earth’s ecosystems by altering the climate and by removing large predators, but scientists rarely study those processes together,” Rasher said. “If we had only studied the effects of climate change on Clathromorphum in the laboratory, we would have arrived at very different conclusions about the vulnerability and future of this species. Our study shows that we must view climate change through an ecological lens, or we’re likely to face many surprises in the coming years.”……..https://www.eurekalert.org/pub_releases/2020-09/blfo-los090420.php
Climate change causing major changes in Arctic insect communities
Climate change recasts the insect communities of the Arctic, EurekAlert, UNIVERSITY OF
HELSINKI Research News 12 Sept 20, Through a unique research collaboration, researchers at the University of Helsinki have exposed major changes taking place in the insect communities of the Arctic. Their study reveals how climate change is affecting small but important predators of other insects, i.e. parasitoids.”Predators at the top of the food web give us a clue to what is happening to their prey species, too. These results increase our understanding of how global warming is changing nature. At the same time, they suggest new inroads for finding answers to big questions in the field of ecology,” says Professor Tomas Roslin from the University of Helsinki and the Swedish University of Agricultural Sciences (SLU).
The researchers’ main discovery was that clear traces of climate change can already be seen in arctic insect communities.
“In areas where summers are rapidly warming, we find a higher proportion of cold-sensitive predators than we might expect based on the previous climate,” Roslin notes.
The study joined research teams working in Greenland, Canada, Russia, Norway, Finland and Iceland, which together compared regions where the climate has changed at different rates and in different ways in recent decades.
Parasitoids are fierce predators but sensitive to changes in climatic conditions
“The climate of the Arctic is currently changing about twice as fast as the global average. Therefore, the Arctic region provides an important laboratory when we try to understand the effects of climate change on nature,” says Tuomas Kankaanpää, lead author of the study and active at the Faculty of Agriculture and Forestry, University of Helsinki.
“To distinguish the key consequences of climate change, we have focused on some of the most important predators in the Arctic, parasitoid wasps and flies. These parasitoids are predators whose larvae develop on or within a single host individual and usually kill it in the process. And now we have found that climate change is dramatically affecting the relative dominance of different types of parasitoids.”………..https://www.eurekalert.org/pub_releases/2020-09/uoh-ccr091020.php
Central Asia’s toxic nuclear legacy
According to Kyrgyz official data, the gamma radiation on tailings pit surfaces are within 17-60 mR/hr; however, in the damaged areas, radiation levels reach 400-500 mR/hr. An exposure to 100 mSv a year (a millisievert, mSv, is equal to 100 milliroentgens, mR) or 10,000 mR is the point where an increase in cancer is clearly evident. At 400-500 mR/hr this would be achieved in 20-25 hours, or just one day. Radionuclides and heavy metals from these tailing pits and dumps are seeping into the surface and groundwater, polluting water and farmland and increasing the risk of cancer for local people.
Birth anomalies are an additional indicator of environmental radioactive contamination. A study by the Institute of Medical Problems showed that the incidence of birth defects in Mailuu-Suu was three times higher than in the country’s second largest city of Osh. Studies have correlated birth defects to the distance of the parents’ residences from radioactive waste sites. Polluted water is the major factor causing the development of congenital malformations, according to research by the Institute of Medical Problems.
Mailuu-Suu: Cleaning up Central Asia’s toxic uranium legacy https://www.thethirdpole.net/2020/09/02/mailuu-suu-cleaning-up-central-asias-toxic-uranium-legacy/
Countries must set aside territorial disputes and work together to clean up radioactive waste seeping into rivers and farmland in the Ferghana Valley – causing an environmental and health catastrophe for people living in the region Janyl Madykova, September 2, 2020 Political tensions between countries in Central Asia have intensified since the collapse of the Soviet Union. Along with border conflicts and water disputes, problems have arisen from residual radioactive waste located in the Kyrgyz town of Mailuu-Suu in the Ferghana Valley, which has caused widespread pollution of river and farmland, and led to major impacts on the health and economy of people in Kyrgyzstan and Uzbekistan.
Industrial-scale uranium mining began in Mailuu-Suu during the Soviet era in 1946 and lasted until 1968. Uranium ore from Europe and China was also processed in Mailuu-Suu during this time.
As a result, the small town of 24,000 people is now surrounded by about 3 million cubic metres of uranium waste left in 23 tailings pits and 13 dumps. These sites have contaminated the Mailuu-Suu river, a major tributary of the Syr Darya which flows through Kyrgyzstan and into Uzbekistan, carrying radioactive waste into the densely populated Ferghana Valley.
The biggest problem is that earthquakes, landslides and heavy rainfall events have intensified in recent years, destroying uranium tailing storage sites along the river and mountain slopes, contaminating surrounding areas. A number of international organisations have worked to prevent further disasters in Mailuu-Suu. The World Bank has allocated more than USD 11 million to clean up uranium tailings. The European Commission launched an initiative in 2015 to remediate the most dangerous sites in Kyrgyzstan, Tajikistan and Uzbekistan.
However, the pollution remains, and Central Asian countries must cooperate to prevent further environmental disasters in the Ferghana Valley, as well as mitigate economic damage and resolve political issues.
A town built on radioactive waste
According to the state surveys there are 92 radioactive and toxic storage facilities across Kyrgyzstan today. The most dangerous of these are the Mailuu-Suu uranium sites, because of numerous hazards threatening the tailing pits. Were these tailing pits destabilised, they would have potentially catastrophic environmental consequences for Kyrgyzstan and the neighbouring countries of Uzbekistan and Kazakhstan, with the radioactive waste contaminating the river as well as the soil and irrigated farmland surrounding it.
Uranium was first discovered in the region in 1933, and within 20 years 10,000 tonnes of uranium oxide was extracted in Mailuu-Suu. Residual radioactive waste in southern Kyrgyzstan currently poses a major environmental threat to the densely populated parts of the Ferghana Valley, home to about 14 million people.
Landslides are the major risk. There are more than 200 landslide-prone locations around Mailuu-Suu. There was little such threat in the 1940s, but landslide activity has intensified since 1954 due to increased rainfall. Landslides in Mailuu-Suu occurred several times in 1988, 1992 and 2002, damaging infrastructure and altering water flow. The most dangerous landslide is Koi-Tash, which happened in 2017 and could block the riverbed and spread radioactive contamination down the river.
The 1950s saw one of the most salient examples of the danger posed by vulnerable waste dumps. In April 1958, as a result of rainfall and high seismic activity, an alluvial dam collapsed into tailings pit #7 in Mailuu-Suu, pushing more than 400,000 cubic metres of radioactive waste into the Mailuu-Suu river, which then spread 30-40 km downstream in irrigated farmland in Uzbekistan. The effects of this disaster have lasted to this day, with the radioactive contamination of the river and surrounding soil and vegetation causing major health problems and fatalities. Such disasters also heighten tensions between the regional states. Continue reading
