Climate predictions not serious enough – new research on clouds
Climate worst-case scenarios may not go far enough, cloud data shows https://www.theguardian.com/environment/2020/jun/13/climate-worst-case-scenarios-clouds-scientists-global-heating Modelling suggests climate is considerably more sensitive to carbon emissions than thought, Jonathan Watts Sat 13 Jun 2020 Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said.Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts said the projections had the potential to be “incredibly alarming”, though they stressed further research would be needed to validate the new numbers.
Modelling results from more than 20 institutions are being compiled for the sixth assessment by the United Nations Intergovernmental Panel on Climate Change, which is due to be released next year.
Compared with the last assessment in 2014, 25% of them show a sharp upward shift from 3C to 5C in climate sensitivity – the amount of warming projected from a doubling of atmospheric carbon dioxide from the preindustrial level of 280 parts per million. This has shocked many veteran observers, because assumptions about climate sensitivity have been relatively unchanged since the 1980s.
“That is a very deep concern,” Johan Rockström, the director of the Potsdam Institute for Climate Impact Research, said. “Climate sensitivity is the holy grail of climate science. It is the prime indicator of climate risk. For 40 years, it has been around 3C. Now, we are suddenly starting to see big climate models on the best supercomputers showing things could be worse than we thought.”
He said climate sensitivity above 5C would reduce the scope for human action to reduce the worst impacts of global heating. “We would have no more space for a soft landing of 1.5C [above preindustrial levels]. The best we could aim for is 2C,” he said.
Worst-case projections in excess of 5C have been generated by several of the world’s leading climate research bodies, including the UK Met Office’s Hadley Centre and the EU’s Community Earth System Model
Timothy Palmer, a professor in climate physics at Oxford University and a member of the Met Office’s advisory board, said the high figure initially made scientists nervous. “It was way outside previous estimates. People asked whether there was a bug in the code,” he said. “But it boiled down to relatively small changes in the way clouds are represented in the models.”
The role of clouds is one of the most uncertain areas in climate science because they are hard to measure and, depending on altitude, droplet temperature and other factors, can play either a warming or a cooling role. For decades, this has been the focus of fierce academic disputes.
Previous IPCC reports tended to assume that clouds would have a neutral impact because the warming and cooling feedbacks would cancel each other out. But in the past year and a half, a body of evidence has been growing showing that the net effect will be warming. This is based on finer resolution computer models and advanced cloud microphysics.
“Clouds will determine humanity’s fate – whether climate is an existential threat or an inconvenience that we will learn to live with,” said Palmer. “Most recent models suggest clouds will make matters worse.”
In a recent paper in the journal Nature, Palmer explains how the new Hadley Centre model that produced the 5+C figure on climate sensitivity was tested by assessing its accuracy in forecasting short-term weather. This testing technique had exposed flaws in previous models, but in the latest case, the results reinforced the estimates. “The results are not reassuring – they support the estimates,” he wrote. He is calling for other models to be tested in a similar way.
“It’s really important. The message to the government and public is, you have to take this high climate sensitivity seriously. [We] must get emissions down as quickly as we can,” he said.
The IPCC is expected to include the 5+C climate sensitivity figure in its next report on the range of possible outcomes. Scientists caution that this is a work in progress and that doubts remain because such a high figure does not fit with historical records.
Catherine Senior, head of understanding climate change at the Met Office Hadley Centre, said more studies and more data were needed to fully understand the role of clouds and aerosols.
“This figure has the potential to be incredibly alarming if it is right,” she said. “But as a scientist, my first response is: why has the model done that? We are still in the stage of evaluating the processes driving the different response.”
While acknowledging the continued uncertainty, Rockström said climate models might still be underestimating the problem because they did not fully take into account tipping points in the biosphere.
“The more we learn, the more fragile the Earth system seems to be and the faster we need to move,” he said. “It gives even stronger argument to step out of this Covid-19 crisis and move full speed towards decarbonising the economy.”
Half of the Earth’s ice-free land is still free from human impact

Half the earth relatively intact from global human influence https://www.eurekalert.org/pub_releases/2020-06/uoc–hte061120.php Study presents clear opportunities to conserve what remains, UNIVERSITY OF CALIFORNIA – DAVIS 14 June 20 Roughly half of Earth’s ice-free land remains without significant human influence, according to a study from a team of international researchers led by the National Geographic Society and the University of California, Davis.The study, published in the journal Global Change Biology, compared four recent global maps of the conversion of natural lands to anthropogenic land uses to reach its conclusions. The more impacted half of Earth’s lands includes cities, croplands, and places intensively ranched or mined. “The encouraging takeaway from this study is that if we act quickly and decisively, there is a slim window in which we can still conserve roughly half of Earth’s land in a relatively intact state,” said lead author Jason Riggio, a postdoctoral scholar at the UC Davis Museum of Wildlife and Fish Biology. The study, published June 5 on World Environment Day, aims to inform the upcoming global Convention on Biological Diversity — the Conference of Parties 15. The historic meeting was scheduled to occur in China this fall but was postponed due to the coronavirus pandemic. Among the meeting’s goals is to establish specific, and higher, targets for land and water protection. Approximately 15 percent of the Earth’s land surface and 10 percent of the oceans are currently protected in some form. However, led by organizations including Nature Needs Half and the Half-Earth Project, there have been bold global calls for governments to commit to protecting 30 percent of the land and water by 2030 and 50 percent by 2050. Intact natural lands across the globe can help purify air and water, recycle nutrients, enhance soil fertility and retention, pollinate plants, and break down waste products. The value of maintaining these vital ecosystem services to the human economy has been placed in the trillions of U.S. dollars annually. CONSERVATION AND COVID-19 The coronavirus pandemic now shaking the globe illustrates the importance of maintaining natural lands to separate animal and human activity. The leading scientific evidence points to the likelihood that SARS-CoV2, the virus that causes the disease COVID-19, is a zoonotic virus that jumped from animals to humans. Ebola, bird flu and SARS are other diseases known to have spilled over into the human population from nonhuman animals. “Human risk to diseases like COVID-19 could be reduced by halting the trade and sale of wildlife, and minimizing human intrusion into wild areas,” said senior author Andrew Jacobson, professor of GIS and conservation at Catawba College in North Carolina. Jacobson said that regional and national land-use planning that identify and appropriately zone locations best suited to urban growth and agriculture could help control the spread of human development. Establishing protections for other landscapes, particularly those currently experiencing low human impacts, would also be beneficial. FROM THE TUNDRA TO THE DESERT Among the largest low-impact areas are broad stretches of boreal forests and tundra across northern Asia and North America and vast deserts like the Sahara in Africa and the Australian Outback. These areas tend to be colder and/or drier and less fit for agriculture. “Though human land uses are increasingly threatening Earth’s remaining natural habitats, especially in warmer and more hospitable areas, nearly half of Earth still remains in areas without large-scale intensive use,” said co-author Erle Ellis, professor of geography at the University of Maryland-Baltimore County. Areas having low human influence do not necessarily exclude people, livestock or sustainable management of resources. A balanced conservation response that addresses land sovereignty and weighs agriculture, settlement or other resource needs with the protection of ecosystem services and biodiversity is essential, the authors note. “Achieving this balance will be necessary if we hope to meet ambitious conservation targets,” said Riggio. “But our study optimistically shows that these targets are still within reach.” |

Climate helped by Europe’s fast-growing mini-forests
Fast-growing mini-forests spring up in Europe to aid climate
Miyawaki forests are denser and said to be more biodiverse than other kinds of woods, Guardian, Hannah Lewis, Sat 13 Jun 2020 Tiny, dense forests are springing up around Europe as part of a movement aimed at restoring biodiversity and fighting the climate crisis.
Often sited in schoolyards or alongside roads, the forests can be as small as a tennis court. They are based on the work of the Japanese botanist Akira Miyawaki, who has planted more than 1,000 such forests in Japan, Malaysia and elsewhere.
Advocates for the method say the miniature forests grow 10 times faster and become 30 times denser and 100 times more biodiverse than those planted by conventional methods. This result is achieved by planting saplings close together, three per square metre, using native varieties adapted to local conditions. A wide variety of species – ideally 30 or more – are planted to recreate the layers of a natural forest.
Scientists say such ecosystems are key to meeting climate goals, estimating that natural forests can store 40 times more carbon than single-species plantations. The Miyawaki forests are designed to regenerate land in far less time than the 70-plus years it takes a forest to recover on its own.
“This is a great thing to do,” said Eric Dinerstein, a wildlife scientist who co-authored a recent paper calling for half of the Earth’s surface to be protected or managed for nature conservation to avoid catastrophic climate change. “So this could be another aspect for suburban and urban areas, to create wildlife corridors through contiguous ribbons of mini-forest.”
The mini-forests could attract migratory songbirds, Dinerstein said. “Songbirds are made from caterpillars and adult insects, and even small pockets of forests, if planted with native species, could become a nutritious fast-food fly-in site for hungry birds.”……. https://www.theguardian.com/environment/2020/jun/13/fast-growing-mini-forests-spring-up-in-europe-to-aid-climate

Credible sources indicate the postponement of the 2020 Olympics enabled the Government’s new decision-making process for release of the waste.
They said the Government’s short extension for the current public consultation was grossly insufficient while COVID-19 measures limited opportunities for input from all affected communities in Japan, as well as those in neighbouring countries, including indigenous peoples.

Risk of fire on a nuclear submarine. France’s lucky escape, due to reactor being removed for overhaul
Why The Catastrophic Fire On A Nuclear Submarine Is Nothing To Gloat About https://www.forbes.com/sites/hisutton/2020/06/14/why-the-catastrophic-fire-on-a-nuclear-submarine-is-nothing-to-gloat-about/#ef9667d2ffd0
As details emerge of the fire aboard the French submarine Perle on Friday, it seems unlikely to me that the boat will be returned to service. Whichever way you look at it, the fire is a terrible blow for the French Navy (Marine Nationale). Their submarine fleet is already stretched. But France’s misfortune brings home a basic reality that it could happen to any navy.
The cause of the fire, which took most of Friday to extinguish, has yet to be determined. Florence Parly, Minister of the Armed Forces, was reported by Naval News as saying on June 13 that the “cause for such a strong (and rapid) fire is still unknown.” She also said that if the boat turns out to be fixable, everything will be done to repair it. Any hint of optimism in this statement may point to the terrible predicament that it will leave the French Navy in if it cannot be repaired.
No Reason To Gloat
You will not find many in the defense community laughing at France’s expense. When a Russian or Chinese warship suffers a similar accident, many casual observers are quick to make jokes. Less so the defense community.
For example on April 13 a Chinese Type-075 assault carrier caught fire in Shanghai. That ship, the first of its type, was being fitted out before delivery. The types of work done during refit are similar to the deep overhaul that Perle was being subject to. Or in December last year a Russian aircraft carrier caught fire.
But the Western defense community is very aware that these accidents could equally apply to their home navies. Overhauling ships and submarines is ‘hot work’ and fires can easily occur.
The fire took 14 hours to put out, from 10.35am until 00.50 am the next morning. This may sound like a long time, but the U.S. Navy had a similar experience dealing with a fire aboard the Los Angeles class submarine USS Miami in 2012. That fire, which was also during an overhaul, lasted 12 hours and caused so much damage that the boat had to be written off. In the American case it turned out that the fire had been started deliberately by a dockyard worker hoping that the alarm would get him off work early.
In general, fires aboard submarines can be harder to put out. This is because of the cramped spaces aboard, and also because there are very few openings into the submarine. And they can be more devastating than a similar fire aboard a surface vessel because the heat can deform the steel hull. On a surface vessel this can be repaired more easily, but with a submarine it can make the hull weaker so that it is no longer safe to dive. This is why I am not optimistic that she will be repairable.
The fire was not as bad as it could have been. Fortunately the nuclear reactor had apparently already been removed. So the fire has not been categorized as a nuclear accident. And the torpedoes and missiles had also been unloaded so there was no risk of them exploding.
Many core systems, such as the combat system and sonar, had also been removed. So if the hull can be saved, then returning her to service is at least feasible. But everything seems to depend on whether the hull itself has been weakened.
Radioactive cloud over Europe in 2017 came from a civilian nuclear reactor

Radioactive cloud over Europe had civilian background https://www.eurekalert.org/pub_releases/2020-06/uom-rco061220.phpIsotope measurements on air filters: researchers investigated undeclared nuclear release / Study in “Nature Communications” 14 June 20
UNIVERSITY OF MÜNSTER A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe’s radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels of what had been detected over Europe in the aftermath of the Fukushima accident. Since no government has assumed responsibility so far, a military background could not be ruled out. Researchers at the Leibniz University Hannover and the University of Münster (both Germany) now found out that the cloud did not originate from military sources – but rather from civilian nuclear activities. Hence, the release of ruthenium from a reprocessing plant for nuclear fuels is the most conclusive scenario for explaining the incident in autumn 2017. The study has been published in the journal Nature Communications.
Background: It is impossible to make a clear distinction between civilian and military sources solely based on measurements of radioactive isotopes of ruthenium. For the first time, researchers from the Institute of Radioecology and Radiation Protection at Leibniz University of Hannover and the Institute of Planetology at Münster University succeeded in quantifying stable ruthenium isotopes in air filters that were released with the radioactive ruthenium. Within the scope of the study, the team left conventional scientific paths: “We usually measure ruthenium isotopes to study the formation history of Earth”, says Prof. Thorsten Kleine from the University of Münster, adding that the methods originally developed to address research questions in planetology were instrumental in solving this mystery. The fact that the airborne ruthenium stemming from nuclear activities occurred in minuscule amounts and were diluted with natural stable ruthenium presented a significant challenge. Through the clean chemical separation of ruthenium fractions from air filters and subsequent high-precision measurements via mass spectrometry, the researchers determined the ratio of stable ruthenium from the nuclear source. The ruthenium isotopic ratios found in the filter are consistent with the signature of a civilian source, in particular the signature of spent nuclear fuel from a nuclear power plant. A military background (such as the production of weapons-grade plutonium) can be ruled out. Furthermore, high-precision measurements enabled the researchers to draw further conclusions. “The isotope signature discovered in the air filter exhibits no similarities with nuclear fuels of conventional Western pressurised or boiling water reactors. Instead, it is consistent with the isotope signature of a specific type of Russian pressurised water reactors – the VVER series. Worldwide, approximately 20 reactors of this type of VVER are currently operational”, specifies Professor Georg Steinhauser from Leibniz University Hannover. Original publication: T. Hopp et al.

Trump wants costly armed nuclear ice-breakers – where will the money come from ?
U.S. Seeks Armed Nuclear Icebreakers For Arctic Show Of Force, David Hambling
Aerospace & Defense, 14 June 20,
President Trump has called for a ‘ready, capable, and available fleet of polar security icebreakers’ to give America a ‘strong presence’ in the Arctic and Antarctic regions. The call comes in a White House memorandum dated June 9 and envisages armed, nuclear-powered icebreakers engaging in operations for both national security and commercial interests. This is hugely ambitious considering that the U.S. currently has a single, ageing, non-nuclear icebreaker, while Russia is rapidly expanding its huge nuclear icebreaker fleet.
Russia has long seen the waters off their northern coast as a key economic asset, both for oil and gas exploration and as a shipping route, anticipating that the emerging Northern Sea Route will attract trade away from the Suez Canal by trimming 40% off the journey from Europe to Asia. Russia has ramped up its Arctic military presence in recent years with new air bases, ships and land forces to support these interests.

India will follow with nuclear weapons testing, if USA resumes testing
If the Donald Trump Resumes U.S. Nuclear Weapons Testing, India Will Follow, Hasan Ehtisham, The National Interest•June 13, 2020
On May 15, according to media reports, the Trump administration conducted serious discussions on whether or not to break the informal ban to carry out a nuclear test explosion. Washington’s intent to resume nuclear testing threatens to elevate already grown strategic tensions with China, Russia, and others. Some analysts comprehended that this is a proper course to influence Russia and China to support Washington’s plan for trilateral talks related to nuclear arms controls and disarmament issues. ……
The head of the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO), Lassina Zerbo, has presaged that any attempt by the United States to recommence nuclear testing would have serious ramifications for global peace and security. While mentioning CTBTO’s close relationship with the U.S. National Laboratories, Zerbo categorically precluded the notion of any requirement for nuclear testing. Chinese Foreign Ministry spokesperson Zhao Lijian has also shown “grave concerns about the report.” He urged the Trump administration to meet its “due obligations and honour its commitment by upholding the purpose and objective of the CTBT.” During the contemporary strategic competition of major powers, an uncertain situation has emerged about any sort of political gains for Washington against Moscow or Shanghai with a nuclear test. The most plausible consequence of a nuclear explosion by the United States at this point will facilitate other countries to resume nuclear testing. Washington will be criticized by other nuclear weapons states for violating the nuclear test moratorium practiced since 1998 by all countries, except North Korea.
Robert Rosner, a professor of physics at the University of Chicago, has evaluated that after the United States others will also resume nuclear testing and “the crucial question is: Who are the others?” In the South Asian strategic scenario, India will be that other country. India, one of the world’s fastest developing nuclear weapons states, has long been waiting for such a mistake, particularly from the United States, so that it could revoke the pledge of nuclear non-testing. It has been unable to do so just because it aspires to become part of the Nuclear Suppliers Group (NSG) and other global regimes. Once the United States resumes nuclear testing, India will find it easier to further demonstrate its nuclear weapon capability.
This latest paradigm shift by the United States allows India to conduct more nuclear testing to assess the design of its thermonuclear weapon which it claimed to have detonated on May 11, 1998, in the Operation Shakti-1. Numerous international experts believe that the results of the thermonuclear test were highly inflated and doubt that the device successfully ignited the second fusion stage of the explosion. The scientist community who coordinated the Operation Shakti-1 in 1998 has concluded that the test was a failure, as the yield of the fusion device never produced the desired results.
Nuclear pundits in India have already materialized a comprehensive and robust nuclear facility to meet any kind of eventuality that could provide India with an opportunity to carry out further nuclear tests. For instance, in 2012, India’s secret nuclear city at Challakere, Karnataka was revealed by independent researchers. Experts have shown apprehensions that the facility will be a major complex of nuclear centrifuges under military control, along with atomic research laboratories, weapons and aircraft testing sites. Once it starts functioning, the facility would enable India to modernize its existing nuclear warheads and the nuclear fuel from domestic reserves will be used for a thermonuclear weapon. India is also working on a uranium enrichment plant from which it will be able to produce about twice as much weapons-grade uranium as New Delhi will need for its operational nuclear weapon programme. That significant excess of the enriched uranium would be used for the development of thermonuclear weapons.
India has already done the necessary homework to manipulate any step the United States may take in the near future. The Defence Research and Development Organisation (DRDO) has signaled the capacity to conduct more nuke tests at short notice. If India alters the status of its moratorium on nuclear testing, then it would not only upset the deterrence balance but most significantly it would start a fresh nuclear arms race in South Asia. Under the pretext of growing Indo-US strategic relations in the region, the U.S. is offering a free ride to India to enhance the nuclear capability by resuming nuclear testing. It is strategically prudent for the U.S. national interest to uphold its commitments regarding the unilateral pledge of nuclear non-testing while ratifying the CTBT. The United States should also press India to continue its moratorium on nuclear weapons testing which was the primary prerequisite for the U.S.-India nuclear deal of 2008. It will reinforce the global standards against nuclear testing and encourage regional stability. https://news.yahoo.com/donald-trump-resumes-u-nuclear-120000804.html

Why doesn’t debt-ridden EDF cut its losses and close its uneconomic UK nuclear reactors
|
Unanswered questions dog UK’s new nuclear plans Climate News Network June 11th, 2020, by Paul Brown A French company has designs on the United Kingdom: new nuclear plans for more reactors, with British consumers footing the bill.
– The French company EDF, a company in a hurry, wants permission to start building two more reactors in the United Kingdom, and it hopes to save money – by arranging for British taxpayers to pay the capital costs of its new nuclear plans. EDF is already building two reactors at Hinkley Point in the West of England, and it is hoping to transfer workers from that site to Suffolk, on the east coast, believing that will help it to save up to 20% of the construction cost of the two planned reactors, because everyone employed there will know already what to do. The catch is that EDF has no money itself to finance the construction and wants the UK government to impose a new tax on British electricity consumers so that they will pay the cost through their electricity bills. The UK has yet to decide whether to go ahead with this tax, euphemistically called a Regulated Asset Base. If adopted, what the scheme means is that the UK consumer will pay EDF’s bills rather than the company having to borrow the money from banks, which are increasingly unlikely to lend money to such expensive schemes because they take so long to build and promise little return. Anxieties abound Meanwhile EDF, which has a Chinese nuclear company as its junior partner, promises to create 25,000 jobs, including 1,000 apprenticeships during construction, and says 900 full-time jobs will be available when Sizewell C, as the station will be called, is complete. If all goes to plan the company hopes to start work in 18 months and says the two reactors will take 10 years to build. It expects them to provide 7% of the UK’s electricity, enough for six million homes. There are many objectors. Some say much of the coastline will be badly affected, including internationally important nature reserves. Others fear the site is highly vulnerable to sea level rise and therefore a danger to the public. Local people also fear that the construction site, with its attendant lorry and commuter traffic, will disrupt their lives for a decade, destroying the important tourist trade. Cheaper options Other more strategic objections, which might weigh heavier with the government, are that nuclear power is very expensive and much cheaper and less controversial alternatives exist, particularly on-shore and off-shore wind and solar power, and biogas. More importantly, a drive for energy efficiency, badly neglected in the UK at present, would render the whole project unnecessary. The problem EDF has is its track record on construction and repairs. The type of reactor it plans to build, the European Pressurised Water Reactor, said by the company to be the most powerful in the world, is proving extremely difficult to build, and till now none has yet been completed outside China. Construction is running more than 10 years late in both Finland and France, and costs continue to escalate.
EDF’s debts are now huge, so big that the French state is working out how to restructure the company by splitting it into a renewables arm (which is profitable) and a nuclear branch. There are serious doubts about the reliability of EDF’s claims and timetables for fixing existing power stations and opening new ones. The company currently owns all of the UK’s operating nuclear reactors, most of which are near the end of their lives, and there are serious doubts about whether they are economic and in some cases even safe. Two reactors at Hunterston in Scotland have serious cracking in the graphite blocks that are part of the control mechanism. The company has spent two years trying to justify continuing to operate the reactors to the Office for Nuclear Regulation (ONR). Similarly, at the other end of the UK, at Dungeness in south-east England, the station is also closed for extensive repairs, an outage that was going to take weeks has now stretched to two years – and the start-up date has just been put back again. Looking on the bright side One of the features of all of EDF’s activities is the extraordinary optimism the company seems to have, particularly about when reactors will be finished or ready to restart after repairs. With the Hunterston reactors restart dates have been announced nine times, only to be postponed each time. This track record led the Climate News Network to ask EDF some searching questions, including why they continued to offer optimistic start-up dates that were repeatedly postponed. We also asked why the company kept the Hunterston and Dungeness stations open at all, since repairing them was costly and they were already near the end of their operating lives. We asked EDF: “At what point do you cut your losses and close the stations permanently?” After five days of pleading for more time to answer, it sent us already published press releases extolling the virtues of the plan to build Sizewell, and several comments. …….HTTPS://CLIMATENEWSNETWORK.NET/UNANSWERED-QUESTIONS-DOG-UKS-NEW-NUCLEAR-PLAN/, l |

Plan for USA’s taxpayers to fund nuclear power exports
US Agency Proposes Financing of Nuclear Power Exports, VOA, By Reuters June 11, 2020 WASHINGTON – A U.S. development agency proposed lifting restrictions that bar the financing of advanced nuclear energy projects abroad, a move the Trump administration hopes will help the industry compete with state-owned companies in China and Russia.
The U.S. International Development Finance Corp., or DFC, late Wednesday opened a 30-day comment period on the proposal. The idea was included in the Trump administration’s Nuclear Fuel Working Group report, released in April, on ways to modernize nuclear energy policy……. The DFC, which replaced the Overseas Private Investment Corp., launched in January with a $60 billion budget. It is seen by analysts as an attempt by Washington to provide an alternative to Beijing’s sweeping Belt and Road Initiative, which sponsors large-scale infrastructure, like nuclear projects, in developing countries. Russia’s state-owned nuclear energy company, Rosatom, is also looking to sell nuclear technology. Ed Lyman, a nuclear power expert at the Union of Concerned Scientists, said it is “utterly irresponsible for the Trump administration to promote the export of unproven and potentially dangerous nuclear technologies to the developing world.” He said Washington should first work with countries to create independent nuclear regulators. …….. Advanced nuclear power is expected to be less expensive than traditional nuclear stations costing tens of billions of dollars. But nonproliferation experts caution that the plants and their supply chains could become targets of attack. https://www.voanews.com/usa/us-agency-proposes-financing-nuclear-power-exports |

Trump’s plan for a nuclear trest – dangerous brinkmanship
A Nuclear Test Would Blow Up in Trump’s Face
The Trump administration doesn’t understand the brinkmanship concept its nuclear diplomacy is based on. Foreign Policy,
BY SARAH BIDGOOD JUNE 11, 2020,
|
The last 42 months have offered a sobering window into the Trump administration’s philosophy on nuclear arms control. On display is its penchant for withdrawing from agreements rather than engaging in dispute resolution—be they the Joint Comprehensive Plan of Action, the Intermediate-Range Nuclear Forces Treaty, or, most recently, the Open Skies Treaty. While many experts see this approach as ill-conceived and damaging to U.S. national security interests, the administration often frames it as a form of brinkmanship designed to signal resolve in an era of strategic competition. The intended message appears to be that the United States will no longer play ball unless its rivals—Russia and China—agree to abide by Washington’s rules.
The latest example of this tendency comes amid reports that the administration might conduct a “rapid” nuclear test to strengthen its hand in negotiations with China and Russia. Experts around the world have denounced this proposal as dangerous, foolhardy, and “catastrophically stupid.” As they point out, were the United States to test for the first time in nearly three decades, it would open the door for the resumption of widespread explosive testing. At the same time, it would undermine the nuclear taboo, hurt the credibility of the nonproliferation regime, and diminish support for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). While all true, these arguments are unlikely to sway this administration, which has shown little regard for existing norms or the disarmament machinery writ large.
What might give decision-makers pause, though, is the fact that a nuclear test is unlikely to be an effective signal in the current context. It would not help deliver President Donald Trump’s goal of a trilateral arms control agreement, but it would provide ample opportunity for misinterpretation and a response in kind. In the process, it would likely put Washington in a worse negotiating position than when it started, making it not only risky but also pointless to boot………..
In short, if decision-makers in Washington do choose to test, this attempt at brinkmanship will certainly fail to convince Russia or China to sit down at the arms control negotiating table. Instead, it will make it all the more likely that the very outcomes trilateral arms control seems to be intended to prevent come to bear—and soon. The good news, then, is that there is plenty of time to walk this ill-conceived and ineffective plan back from the brink. In this instance, restraint—such as it is—may be the most effective nuclear signal this administration could possibly send. https://foreignpolicy.com/2020/06/11/nuclear-test-arms-control-trump-united-states-brinkmanship/

Fire on French submarine – luckily its nuclear reactor, nuclear fuel, had been removed for overhaul
|
Finally at 9:36 p.m local time the Mediterranean Maritime Prefecture reported that the fire had been brought under control by completely flooding the rear compartments of the boat with foam, further noting that the “reactor rooms remains untouched.”…….. Just as importantly, the ship’s 48 megawatt pressurized water nuclear reactor, nuclear fuel, and (conventional-only) weapons had been removed when the submarine entered the drydock in January 2020 for an overhaul by Naval Group due for completion by February 2021. For that reason, the local maritime prefecture claims there is no possibility of radioactive contamination from the incident.
The firefighting effort reportedly involved 30 specialist naval firefighters with support from a firefighting boat, as well as additional specialists scrambled from Marseilles, 11 specialized ground-based firefighting vehicles, and at least 10 ESNA submariners to advise the firefighters. However, there are growing fear that the Perle may have sustained too much damage to be saved. A veteran submariner told the local paper Var Matin “If the thick hull [made of 80HY high-tensile steel]…is deformed, the boat is screwed.” The cause of the blaze is speculated to possibly be faulty welding or a high-pressure cutting gone awry. France’s Nuclear Submarine Force French periodical LeMonde warned that should the Perle suffer “irremediable damage,” there was the possibility “the entire organization of French nuclear deterrence may have to be rethought. And the Navy may have to give up on certain strategic missions.” The Perle does not actually carry any nuclear weapons. However, one of the primary roles of French attack submarines is protecting the four larger Triomphant-class nuclear-powered ballistic missile submarines (SSBNs) from hostile submarines. Indeed, the SSBN Le Téméraire conducted a test launch of an unarmed M51 nuclear ballistic missile just the day prior. France perceives these submarines as performing a vital role in strategic nuclear deterrence, or “dissuasion” as it’s called in France………. Establishing the cause of the accident that may put out of action a valuable strategic asset will also be a priority for Defense Minister Florence Parley, particularly given how much more serious the incident might have been had weapons, the reactor and/or additional personnel had been onboard. For now the citizens of Toulon can only be thankful that loss of life was averted and that there is no apparent risk of contamination. The French Navy will have to take stock of the damage, adjust its plans for its SSN fleet accordingly—and consider how it can minimize the odds of another such accident occurring. https://www.forbes.com/sites/sebastienroblin/2020/06/12/a-french-submarine-caught-fire-in-drydock-it-could-lead-paris-to-rethink-its-nuclear-deterrence-strategy/#4addae213d05 |

Global heating to bring more frequent, more extreme, ocean waves
EXTREME WAVES SET TO BE BIGGER AND MORE FREQUENT
As the planet warms, researchers are warning that the frequency and magnitude of extreme wave events may rise by around 10 per cent by the end of century, increasing flood risks. Pursuit, By Dr Alberto Meucci and Professor Ian Young University of Melbourne, 13 June 20
When most of us think about what climate change will do to our coastlines we tend to focus on how sea-levels are rising as the polar ice caps melt and the oceans warm. But that is only part of the story.
What many don’t realise is that at the same time as sea levels are rising, storms are increasing in magnitude and frequency, resulting in larger ocean waves. These waves increase coastal erosion and the risk of flooding.
Our new research suggests that by the end of the century the magnitude of extreme wave events will have increased by up to 10 per cent over extensive ocean regions, and the frequency of storms that generate extreme waves will have increased by five to 10 per year.
This may not sound like a big increase, but it means that almost 60 per cent of the world’s coastline will experience larger and more frequent extreme waves.
At a time when 290 million people already live below the 100-year flood level (that is, they live below levels where there is at least a one per cent probability of flooding every year), an increase in the risk of extreme wave events may be catastrophic, as larger and more frequent storms will cause more flooding and coastline erosion.
Extremes are defined as unexpected, unusual and sometimes unseasonal events. Like extreme floods, extreme waves are classified by the frequency with which they tend to occur, and this frequency drives the design requirements for ocean structures or coastal defences. For example, defences may be designed to cope with a 100-year wave event.
Extreme ocean waves generated by strong surface winds can reach heights of over 20 meters at the high latitudes of the globe – that’s as high as four double-decker buses stacked on top of each other.
But the surface winds that drive wave heights are in turn driven by the climate system, and so are subject to climate change. A warming planet is causing stronger and more frequent storm winds which in turn trigger larger and more frequent extreme waves, and the 100-year events may begin to occur every 50 or even 20 years.
Estimating the probability of occurrence of extreme waves is challenging, let alone estimating how their frequency and magnitude may change in the future. This is due to the small number of ocean observations available.
The buoys and offshore platforms scientists use to observe ocean movements are sparsely distributed, and satellite measurements are limited in how often they sample a single location.
But advances in computing technology and the modelling of data, allows us to simulate the Earth’s changing climate under different wind conditions, recreating thousands of simulated storms to evaluate the magnitude and frequency of extreme events.
Our research used a unique statistical ensemble approach, where we pooled data from an unprecedented collection of thousands of modelled ocean wave extremes to estimate future extreme events. These extremes were derived from global wave models based on wind forces generated from seven different global climate models.
The vast amount of modelled ocean extremes generated allowed us to apply an ensemble statistical analysis that reduces the uncertainty around the estimation of future projections of extremes. ……..

U.S. nuclear industry looks for salvation to hydrogen production – clutching at straws?
|
Hydrogen May Be a Lifeline for Nuclear—But It Won’t Be Easy, Power, Jun 11, 2020, by Sonal Patel Four U.S. nuclear generators—Energy Harbor, Xcel Energy, Exelon, and Arizona Public Service (APS)—are making headway on projects to demonstrate hydrogen production at nuclear plants, but scaling those efforts up to net new end-users and sources of revenue is still ridden with hurdles, company officials said in a panel discussion at the American Nuclear Society’s (ANS’s) virtual 2020 annual meeting on June 9………
The economics are especially important for Exelon, the nation’s largest nuclear generator, and exploring hydrogen production is a natural evolution to keep its plants financially afloat amid stagnating load growth and challenging economics in competitive energy markets, Greenlee said.
Energy Harbor faces similar predicaments. In 2018, the independent power producer—which was known as FirstEnergy Solutions until Feb. 27, when it completed Chapter 11 restructuring—had planned to shutter Davis-Besse in 2020; along with the twin-unit 1,872-MW Beaver Valley Power Station in Shippingport, Pennsylvania, in 2021; and the Perry Nuclear Power Plant in Perry, Ohio, in 2021. Last year, Energy Harbor pushed for and won nuclear subsidies in Ohio to keep the Davis-Besse and the Perry nuclear plants open through 2027, and this March, it said Beaver Valley would remain open.
Like Energy Harbor, Exelon helped enact the Future Energy Jobs Act in December 2016 (it went into effect in June 2017), to keep Exelon’s Clinton and Quad Cities plants running. Exelon also strongly backed New York’s Clean Energy Standard, a measure that became effective in April 2017, to preserve the at-risk Nine Mile Point, FitzPatrick, and Ginna reactors in upstate New York. And in 2018, New Jersey also enacted zero-emission credits (ZECs) to bolster profitability of the Hope Creek plant, which is owned by PSEG, and Salem, whose output Exelon owns jointly with PSEG.
As Greenlee noted, Exelon has since 2018 been seeking ways to “repurpose” its nuclear plants to make them more viable. The company’s efforts included convening academic experts, former employees, and former federal regulators in a brainstorm session. “And over the last several years, what we have boiled that table down to is, basically, hydrogen,” he said. “Hydrogen is what we want to look at going forward. We think it fits in with potentially a future hydrogen economy.” …….https://www.powermag.com/hydrogen-may-be-a-lifeline-for-nuclear-but-it-wont-be-easy/
