Climate change brings a boom in jellyfish, and a threat to nuclear reactors
Jellyfish are causing mayhem as pollution, climate change see numbers boom, ABC, RN By Hong Jiang and Sasha Fegan for Late Night Live 6 Jan 19 Jellyfish have been around for at least 500 million years — they’re older than dinosaurs and even trees.Science writer Juli Berwald calls them “ghosts from the true garden of Eden”.
“An intelligence of a sort has allowed them to make it through the millennia,” she says.
And they’re not going anywhere.
In fact, the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world. Their propensity to breed fast and prolifically means jellyfish can disrupt ocean ecosystems in a flash.
And their effects aren’t contained to the sea.
In places like Sweden, Israel, the US and the Philippines, power plants have been affected by blooms of jellyfish.
“So many jellyfish were swept into the power system … that it shut down the power system through much of this one island in the Philippines,” Ms Berwald says. People thought that perhaps there was a coup going on, but there wasn’t, it was just the jellyfish.”
Jellyfish have also caused plants to shut down in Japan.
“One jellyfish scientist from Japan told me that the first threat to the electric system in Japan is earthquakes, but the second is jellyfish,” Berwald says.
“We are dealing with a ubiquitous creature.”
A human cause
Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.
Jellyfish also fare better than many other sea creatures in polluted waters, as they don’t need much oxygen.
Berwald says that can give them the upper hand over predators.
“They can sort of slip into polluted waters, into low oxygen waters, and hide from predation there better than a fish that has a higher oxygen demand,” she says…….. https://www.abc.net.au/news/2019-01-06/the-magic-and-mayhem-of-jellyfish/10377112
Historical cooling periods are still playing out in the deep Pacific
https://www.eurekalert.org/pub_releases/2019-01/hjap-hcp010419.php– 4 Jan 19, Whereas most of the ocean is responding to modern warming, the deep Pacific may be cooling, HARVARD JOHN A. PAULSON SCHOOL OF ENGINEERING AND APPLIED SCIENCES The ocean has a long memory. When the water in today’s deep Pacific Ocean last saw sunlight, Charlemagne was the Holy Roman Emperor, the Song Dynasty ruled China and Oxford University had just held its very first class. During that time, between the 9th and 12th centuries, the earth’s climate was generally warmer before the cold of the Little Ice Age settled in around the 16th century. Now, ocean surface temperatures are back on the rise but the question is, do the deepest parts of the ocean know that?
Researchers from the Woods Hole Oceanographic Institution and Harvard University have found that the deep Pacific Ocean lags a few centuries behind in terms of temperature and is still adjusting to the advent of the Little Ice Age. Whereas most of the ocean is responding to modern warming, the deep Pacific may be cooling.
The research is published in Science.
“Climate varies across all timescales,” said Peter Huybers, Professor of Earth and Planetary Sciences in the Department of Earth and Planetary Sciences and of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences and co-author of the paper. “Some regional warming and cooling patterns, like the Little Ice Age and the Medieval Warm Period, are well known. Our goal was to develop a model of how the interior properties of the ocean respond to changes in surface climate.”
What that model showed was surprising.
“If the surface ocean was generally cooling for the better part of the last millennium, those parts of the ocean most isolated from modern warming may still be cooling,” said Jake Gebbie, a physical oceanographer at Woods Hole Oceanographic Institution and lead author of the study.
The model is a simplification of the actual ocean. To test the prediction, Gebbie and Huybers compared the cooling trend found in the model to ocean temperature measurements taken by scientists aboard the HMS Challenger in the 1870s and modern observations from the World Ocean Circulation Experiment of the 1990s.
The HMS Challenger, a three-masted wooden sailing ship originally designed as a British warship, was used for the first modern scientific expedition to explore the world’s ocean and seafloor. During the expedition from 1872 to 1876, thermometers were lowered into the ocean depths and more than 5,000 temperature measurements were logged.
“We screened this historical data for outliers and considered a variety of corrections associated with pressure effects on the thermometer and stretching of the hemp rope used for lowering thermometers,” said Huybers.
The researchers then compared the HMS Challenger data to the modern observations and found warming in most parts of the global ocean, as would be expected due to the warming planet over the 20th Century, but cooling in the deep Pacific at a depth of around two kilometers depth.
“The close correspondence between the predictions and observed trends gave us confidence that this is a real phenomenon,” said Gebbie.
These findings imply that variations in surface climate that predate the onset of modern warming still influence how much the climate is heating up today. Previous estimates of how much heat the Earth had absorbed during the last century assumed an ocean that started out in equilibrium at the beginning of the Industrial Revolution. But Gebbie and Huybers estimate that the deep Pacific cooling trend leads to a downward revision of heat absorbed over the 20th century by about 30 percent.
“Part of the heat needed to bring the ocean into equilibrium with an atmosphere having more greenhouse gases was apparently already present in the deep Pacific,” said Huybers. “These findings increase the impetus for understanding the causes of the Medieval Warm Period and Little Ice Age as a way for better understanding modern warming trends.”

New nuclear technology is NOT a solution to climate change
Debate Continues: Can New Technology Save
Nuclear Power? Power, 01/01/2019 | Kennedy Maize.………Are advanced nuclear reactor designs the answer to the decades-long doldrums for nuclear power? For the U.S., a National Academy of Sciences (NAS) panel led by long-time nuclear advocate M. Granger Morgan of Carnegie Mellon University, issued a pessimistic report last July—US nuclear power: The vanishing low-carbon wedge.
The academy’s report found, “While advanced reactor designs are sometimes held up as a potential solution to nuclear power’s challenges, our assessment of the advanced fission enterprise suggests that no US design will be commercialized before midcentury.” That’s a chilling indictment for all advanced LWRs. The crux of the Morgan report is an assessment that the economic hurdles for nuclear in the U.S. are insurmountable.………
Peter Bradford, a veteran electric utility regulator and nuclear skeptic who served on the U.S. Nuclear Regulatory Commission (NRC) from 1977 to 1982, agrees that nuclear power in the U.S. is priced out of the market. “Even if, for once, they could contain or level out the costs,” he told POWER, “new nuclear is so far outside the competitive range. They have to cut costs and they can’t cut costs without building a bunch [of reactors]. That really isn’t in the cards.”
Nor does Bradford see new nuclear as a way to combat global warming. “Even if it is scaled up much faster than anything now in prospect, it cannot provide more than 10% to 15% of the greenhouse gas displacement that is likely to be needed by mid-century. Not only can nuclear power not stop global warming, it is probably not even an essential part of the solution to global warming,” he wrote in 2006. Since then, he argues, the declining costs of renewables and energy efficiency swamp nuclear economics even further.
While advocates call for setting a price on carbon to reward carbon-free generation, Bradford said that is a weak reed. “At any given level” of carbon prices, he said, “it is going to wind up benefiting renewables and storage,” not nuclear. A reasonable carbon price, he argued, “might not be enough to keep existing plants running.”
SMRs to the Rescue?….
while smaller nuclear reactors are an appealing technological approach to keeping nuclear in the generating mix, they come with their own set of problems.
On closer inspection, said the NAS panel, “Our results reveal that while one light water SMR module would indeed cost much less than a large LWR, it is highly likely that the cost per unit of power will be higher. In other words, light water SMRs do make nuclear power more affordable but not necessarily more economically competitive for power generation.”
Given the “economic premium” of SMRs, along with “the considerable regulatory burden associated with any nuclear reactor, we do not see a clear path forward for the United States to deploy sufficient numbers of SMRs in the electric power sector to make a significant contribution to greenhouse gas mitigation by the middle of this century,” the report says. Economist Kee echoed that conclusion. When it comes to SMRs, he said there “is a lot of work to do and not much time to do it.”
SMRs also face a challenge of demonstrating their viability: Making an economic or climate impact requires many reactors. Neil Alexander, a Canadian nuclear consultant, wrote recently, “Everything about SMRs such as the cost of construction, availability of fuel, cost of shared services, availability of trained operators, and cost of research needed to resolve emerging challenges, only work economically when the unit is in a fleet. A FOAK [first-of-a-kind] cannot stand alone and the barrier to entry that the industry faces is more akin to the ‘First Dozen of a Kind.’ ”
Portland, Oregon-based NuScale appears to be the leader in developing SMR technology (Figure 4 on original). It is taking Alexander’s advice. NuScale has a customer for a 12-unit (720-MW) station: Utah Associated Municipal Power System (UAMPS), which has a site at the Department of Energy’s (DOE’s) Idaho National Laboratory (INL). UAMPS will own the project and Energy Northwest, a municipal joint action agency that operates the Columbia nuclear station near Richland, Washington, will run the plant. Columbia is a 1,100-MW boiling water reactor.
NuScale recently selected BWX Technologies (BWXT) of Lynchburg, Virginia, to begin engineering work leading up to the manufacture of the 60-MW NuScale reactors. BWXT, created after reactor builder Babcock & Wilcox (B&W) emerged from bankruptcy in 2006, has deep experience in the U.S. naval reactor program. NuScale has received a commitment of some $200 million from the DOE. Global engineering firm Fluor Corp. is the majority investor in NuScale.
Ironically, BWXT was the early leader in the SMR race, with its 195-MW mPower pressurized water reactor design. After spending some $400 million on the mPower venture (including $100 million from the DOE), B&W declared it officially dead in March 2017. Rod Adams, who worked on the project for B&W, had this epitaph for the mPower project, “There was simply too much work left to do, too much money left to invest, and an insufficient level of interest in the product to allow continued expenditures to clear corporate decision hurdles.”
NuScale still has a long way to go to demonstrate the validity of its SMR. The company said it expects the Nuclear Regulatory Commission (NRC) will approve the NuScale reactor design in September 2020. UAMPS will also have to get NRC approval for a combined construction and operating license for the site at INL. Nonetheless, NuScale’s optimistic schedule projects commercial operation “by the mid-2020s.”
Past experience suggests that nuclear construction schedules are made to be broken. SMRs pose unique challenges to federal regulators, both in the reactor designs and in operational issues such as staffing levels and communications among 12 discrete units, particularly if they are used to follow load. Additionally, power prices in the Western U.S. are already low and natural gas is driving them lower.
Recognizing the challenges to deploying SMRs, the DOE in November issued a report suggesting state standards and incentives, modeled on those boosting renewables, be applied to SMR technology. But, as POWER reported, “To make a meaningful impact, nearly $10 billion in incentives would be needed to deploy 6 GW of SMR capacity by 2035.”
Beyond the LWR?
Several efforts are in place to replace conventional LWRs with other approaches to splitting atoms to generate power. Admittedly longshots, these build-on technologies go back to the early days of civilian nuclear power, and were previously abandoned in favor of the proven LWR designs.
The highest profile of the LWR apostates is TerraPower, based in Bellevue, Washington, and backed by Microsoft founder and multi-billionaire Bill Gates. [ Ed note: TerraPower has now abandoned this joint project with China] Founded in 2006, TerraPower is working on a liquid-sodium-cooled breeder-burner machine that can run on uranium waste, while it generates power and plutonium, with the plutonium used to generate more power, all in a continuous process.
Liquid sodium has advantages over pressurized water as a coolant, including better heat transfer. It also does not act as a moderator to slow neutrons, which allows for breeding plutonium. Sodium coolant has its own set of problems. Sodium catches fire when exposed to oxygen so coolant leaks can be devastating, as has happened in the past.
Nuclear power father Adm. Hyman Rickover, after a bad experience with the Seawolf-class submarine sodium-cooled reactor—the second subs to use LWR technology after the USS Nautilus—commented that sodium-cooled systems were “expensive to build, complex to operate, susceptible to prolonged shutdown as a result of even minor malfunctions, and difficult and time-consuming to repair.” TerraPower hopes to have commercial machines operating in the late 2020s, but industry insiders have reported that the company’s prototype reactor being built in China has experienced major problems.
Another approach to bypass LWRs is the molten salt reactor, long a favorite of nuclear pioneer Alvin Weinberg. A Canadian firm, Terrestrial Energy, is pushing a 190-MW SMR design using the technology Weinberg developed at Oak Ridge National Lab in the mid-1960s. Molten salt technology operates at close to atmospheric temperature and combines the fuel and the coolant. Terrestrial plans to use the technology to power an SMR, with a target date for the late 2020s. Molten salt poses new engineering challenges for nuclear reactors. One nuclear observer commented, “I prefer solid fuel” to the liquid fuel-coolant in the molten salt reactor.
Finally, developers are looking at abandoning uranium as the primary nuclear fuel. Instead, the idea is to use thorium, one of the most-common elements on the planet. Thorium is a slightly radioactive metal. But thorium is not fissile—able to undergo nuclear fission—so it has to be irradiated with enriched uranium in order to be transmuted into fissile U-233.
Thorium’s chief attribute is that the fuel is so plentiful. Terrestrial Energy has shown interest in using thorium in its molten salt reactors, along with low-enriched uranium that is used in the design it is pursuing in Canada. Skeptics suggest that thorium is an answer in search of a question, given the easy availability of uranium, particularly in seawater. Uranium shortages, forecast in the 1960s when advocates first suggested using thorium, have never materialized.
The Union of Concerned Scientists (UCS) is currently wrapping up a study of the new, non-LWR reactor designs. Physicist Ed Lyman, a veteran UCS staffer, told POWER, “Our overall conclusion is that vendors, DOE, and advocates are greatly exaggerating the benefits” of the technologies. “The whole landscape is not compelling. We question whether the best direction for nuclear power is to go off on these more exotic tangents,” rather than focus on making LWRs cheaper and safer. “That’s potentially a better near term” investment, he said.
The original generations of civilian nuclear power failed to live up to their promises. The U.S. nuclear industry stalled in the mid-1970s and has not recovered, despite repeated government and industry attempts at a restart.
Gen III reactors were aimed at overcoming the perceived safety and economic shortcomings of the original machines. As those new designs appear to be falling short, attention has shifted to SMRs or new approaches that abandon traditional light-water technology. Whether they will live up to their billing remains a serious, open question. ■

Tons of methane being released into atmosphere by melting ice sheets
Melting ice sheets release tons of methane into The Greenland Ice Sheet emits tons of methane according to a new study, showing that subglacial biological activity impacts the atmosphere far more than previously thought.
An international team of researchers led by the University of Bristol camped for three months next to the Greenland Ice Sheet, sampling the meltwater that runs off a large catchment (> 600 km2) of the Ice Sheet during the summer months.
As reported in Nature, using novel sensors to measure methane in meltwater runoff in real time, they observed that methane was continuously exported from beneath the ice.
They calculated that at least six tons of methane was transported to their measuring site from this portion of the Ice Sheet alone, roughly the equivalent of the methane released by up to 100 cows.
Professor Jemma Wadham, Director of Bristol’s Cabot Institute for the Environment, who led the investigation, said: “A key finding is that much of the methane produced beneath the ice likely escapes the Greenland Ice Sheet in large, fast flowing rivers before it can be oxidized to CO2, a typical fate for methane gas which normally reduces its greenhouse warming potency.”
Methane gas (CH4) is the third most important greenhouse gas in the atmosphere after water vapour and carbon dioxide (CO2). Although, present in lower concentrations that CO2, methane is approximately 20-28 times more potent. Therefore smaller quantities have the potential to cause disproportionate impacts on atmospheric temperatures. Most of the Earth’s methane is produced by microorganisms that convert organic matter to CH4 in the absence of oxygen, mostly in wetlands and on agricultural land, for instance in the stomachs of cows and rice paddies. The remainder comes from fossil fuels like natural gas.
While some methane had been detected previously in Greenland ice cores and in an Antarctic Subglacial Lake, this is the first time that meltwaters produced in spring and summer in large ice sheet catchments have been reported to continuously flush out methane from the ice sheet bed to the atmosphere.
Lead author, Guillaume Lamarche-Gagnon, from Bristol’s School of Geographical Sciences, said: “What is also striking is the fact that we’ve found unequivocal evidence of a widespread subglacial microbial system. Whilst we knew that methane-producing microbes likely were important in subglacial environments, how important and widespread they truly were was debatable. Now we clearly see that active microorganisms, living under kilometres of ice, are not only surviving, but likely impacting other parts of the Earth system. This subglacial methane is essentially a biomarker for life in these isolated habitats.”
Most studies on Arctic methane sources focus on permafrost, because these frozen soils tend to hold large reserves of organic carbon that could be converted to methane when they thaw due to climate warming. This latest study shows that ice sheet beds, which hold large reserves of carbon, liquid water, microorganisms and very little oxygen – the ideal conditions for creating methane gas – are also atmospheric methane sources.
Co-researcher Dr Elizabeth Bagshaw from Cardiff University added: “The new sensor technologies that we used give us a window into this previously unseen part of the glacial environment. Continuous measurement of meltwater enables us to improve our understanding of how these fascinating systems work and how they impact the rest of the planet.”
With Antarctica holding the largest ice mass on the planet, researchers say their findings make a case for turning the spotlight to the south. Mr Lamarche-Gagnon added: “Several orders of magnitude more methane has been hypothesized to be capped beneath the Antarctic Ice Sheet than beneath Arctic ice-masses. Like we did in Greenland, it’s time to put more robust numbers on the theory.”
This study was a collaboration between Bristol University, Charles University (Czechia), the National Oceanography Centre in Southampton, Newcastle University, the University of Toronto (Canada), the Université Libre de Bruxelles (Belgium), Cardiff University (UK), and Kongsberg Maritime Contros (Germany). It was funded by the Natural Environment Research Council (NERC), with additional funds from the Leverhulme Trust, the Czech Science Foundation, the Natural Sciences and Engineering Research Council of Canada, and the Fond de Recherche Nature et Technologies du Québec (Canada).

USA’s new Speaker in Congress, Nancy Pelosi states climate change as ‘The existential threat of our time’

‘The existential threat of our time’: Pelosi elevates climate change on Day One, Politico, By ANTHONY ADRAGNA and ZACK COLMAN , 01/03/2019 Democrats put climate change back on the forefront of their governing agenda Thursday, portraying the issue as an “existential threat” even as the caucus remains split over how forcefully to respond.
Speaker Nancy Pelosi brought up the issue in her opening address while touting a new select panel to come up with ideas on how to solve it, and the Energy and Commerce Committee announced that climate change would be the subject of its very first hearing this year……..
Progressives, led in part by Rep. Alexandria Ocasio-Cortez (D-N.Y.), are tugging the caucus into a more urgent posture that they say best reflects what scientists have called for to avert climate change. The Intergovernmental Panel on Climate Change warned last year that the world has 12 years to put policies in place to avoid irreversible, catastrophic effects of climate change. ……..https://www.politico.com/story/2019/01/03/nancy-pelosi-climate-change-congress-1059148

The world has a window of about 12 years left – to act on climate change
The Story of Sustainability in 2018: “We Have About 12 Years Left” Harvard Business Review 27th Dec 2018 Andrew Winston, – We have about 12 years left. That’s the clear message from a monumental study from the Intergovernmental Panel on Climate Change (IPCC).
To avoid some of the most devastating impacts of climate change, the world must slash carbon emissions by 45% by 2030, and completely decarbonize by 2050 (while, in the meantime, emissions are still rising).
The IPCC looked at the difference between the world “only” warming two degrees Celsius (3.8°F) — the agreed upon goal at global climate summits in Copenhagen and Paris — or holding warming to just 1.5 degrees. Even the latter, they say, will require a monumental effort “unprecedented in terms of scale.”
We face serious problems either way, but every half degree matters a great deal in human, planetary, and economic losses.
It wasn’t just the IPCC that told a stark story. Thirteen U.S. government agencies issued the U.S. National Climate Assessment, which concluded that climate change could knock at least 10% off of GDP. Other studies tell us that sea
level rise is going to be worse than we thought, Antarctica is melting three times faster than a decade ago, and Greenland is losing ice quickly as well. If both those ice sheets go, sea level rise could reach 200-plus feet, resulting in utter devastation, including the loss of the entire Atlantic seaboard (Boston, New York, D.C., etc.), all of Florida, London,
Stockholm, Denmark, Paraguay, and land now inhabited by more than 1 billion Asians). https://hbr.org/2018/12/the-story-of-sustainability-in-2018-we-have-about-12-years-left
Donald Trump and our imperilled planet
Trump Imperils the Planet https://www.nytimes.com/2018/12/26/opinion/editorials/climate-change-environment-trump.html
Endangered species, climate change — the administration is taking the country, and the world, backward.
By The Editorial Board The editorial board represents the opinions of the board, its editor and the publisher. It is separate from the newsroom and the Op-Ed section. Dec. 26, 2018
It’s hard to believe but it was only three years ago this month — just after 7 p.m., Paris time, Dec. 12, to be precise — that delegates from more than 190 nations, clapping and cheering, whooping and weeping, rose to celebrate the Paris Agreement — the first genuinely collective response to the mounting threat of global warming. It was a largely aspirational document, without strong legal teeth and achieved only after contentious and exhausting negotiations. But for the first time in climate talks stretching back to 1992, it set forth specific, numerical pledges from each country to reduce emissions so that together they could keep atmospheric temperatures from barreling past a point of no return.
- Two weeks ago, delegates met at a follow-up conference in Katowice, Poland, to address procedural questions left unsettled in Paris, including common accounting mechanisms and greater transparency in how countries report their emissions. In this the delegates largely succeeded, giving rise to the hope, as Brad Plumer put it in The Times, that “new rules would help build a virtuous cycle of trust and cooperation among countries, at a time when global politics seems increasingly fractured.”
- But otherwise it was a hugely dispiriting event and a fitting coda to one of the most discouraging years in recent memory for anyone who cares about the health of the planet — a year marked by President Trump’s destructive, retrograde policies, by backsliding among big nations, by fresh data showing that carbon dioxide emissions are still going up, by ever more ominous signs (devastating wildfires and floods, frightening scientific reports) of what a future of unchecked greenhouse gas emissions is likely to bring.
- The conference itself showcased the very fossil fuels that scientists and most sentient people agree the world must rapidly wean itself from. Poland’s president, Andrzej Duda, set the tone by declaring he had no intention of abandoning coal, which provides nearly four-fifthsof Poland’s electricity. The United States and three other major oil producers — Saudi Arabia, Kuwait and Russia — refused to endorse an alarming report issued in October by the United Nations scientific panel on climate change calling for swift reductions in fossil fuel use by 2030 to avoid the worst consequences of climate change, which it said were approaching much faster than anyone had thought.
Wells Griffith, Mr. Trump’s international energy and climate adviser, managed in one quote to summarize the dismissiveness of the American delegation and its fealty to the president’s apparently unshakable conviction that anything that helps the environment must inevitably hurt the economy. “The United States has an abundance of natural resources and is not going to keep them in the ground,” he said. “We strongly believe that no country should have to sacrifice their economic prosperity or energy security in pursuit of environmental sustainability.” The administration is full of zero-sum philosophers like Mr. Griffith. The idea that sustainability may be a necessary condition of future economic growth appears never to have crossed their minds.
Further depressing the proceedings were recent defections and political troubles in countries that, along with the United States, had been expected to lead the way to a low-carbon energy future. Germany, which long ago walked away from carbon-free nuclear power, is having a hard time cutting back on coal because of political opposition. In Australia, a prime minister was kicked out of officebecause he wanted to reduce the use of coal, which Australia produces in abundance. China, despite admirably aggressive investments in wind and solar power, has yet to get a firm grip on its emissions from coal-fired plants. The new president-elect of Brazil, Jair Bolsonaro, not only named an outspoken climate-change denier as his foreign minister but also, reversing his predecessors’ policy, pledged to open up the Amazon to mining and farming. This will threaten biodiversity in one of the world’s great rain forests while crippling its ability to act as a sink for carbon emissions.
No country’s backsliding, of course, compares with Mr. Trump’s. Determined to demolish President Barack Obama’s entire climate strategy, Mr. Trump has in the past year replaced Mr. Obama’s clean-power plan, which was aimed at reducing carbon dioxide emissions from power plants, with an essentially useless substitute that would emit 12 times the pollution envisaged by the Obama plan. He has proposed weakening a major Obama regulation requiring automakers to nearly double the fuel economy of passenger vehicles by 2025. (This rollback, The Times reported this month, came after a lot of whining by oil interests, not, as one might suspect, from the auto companies, which had accepted the challenge.) And the Environmental Protection Agency and the Interior Department have taken multiple steps to roll back Obama-era efforts to control emissions of methane, a greenhouse gas many times more powerful than carbon dioxide. These three programs formed the basis of Mr. Obama’s pledge at the 2015 Paris meeting to reduce America’s greenhouse gas emissions by 26 percent to 28 percent below 2005 levels by 2025.
The health and environmental effects of the Trump rollbacks, as documented by a Times investigation published this week, are far-reaching and potentially devastating.
This holiday season has brought more gifts to fossil fuel interests; every day is Christmas Day for the likes of Murray Energy and ExxonMobil. This month, the E.P.A. proposed killing an Obama rule that would effectively block the construction of new coal-fired power plants. The Interior Department relaxed restrictions on oil and gas drilling in areas inhabited by the sage grouse, a threatened bird. Also in December, the department released an environmental-impact statement that would open all or part of the 1.5 million-acre coastal plain of the Arctic National Wildlife Refuge to leasing and exploration. The area had been off limits to drilling for decades until Congress, late last year, approved an amendment sponsored by Senator Lisa Murkowski, an Alaska Republican, to open it up.
All this is fundamentally Mr. Trump’s doing. A series of early executive orders established the pro-fossil fuel policy framework; Scott Pruitt, the E.P.A. administrator, and Ryan Zinke, the interior secretary, filled in the details. Mr. Pruitt has left Washington and Mr. Zinke is in his final days, both finishing under ethical clouds. They will deserve, along with Mr. Trump, history’s censure for doing virtually nothing to move to a more responsible energy future — and for not doing so at just the moment when the world needed the kind of leadership that Mr. Obama and his secretary of state, John Kerry (and Bill Clinton and Al Gore before them), tried to provide.
The numbers are not great. The goal in Paris was to keep warming from exceeding 2 degrees Celsius over preindustrial levels, and if possible to hold the line at 1.5 degrees, thresholds that scientists deemed unacceptably risky. Delegates knew that even if every country managed to fulfill its individual pledges, the world would be on pace for 3 degrees of warming in this century. So they agreed to tighten the targets as time went on, but instead they’ve slid backward. Many large emitters are not on track to meet their self-imposed goals. That includes America, despite the retirement of many coal-fired plants in favor of cleaner natural gas, the increasing cost competitiveness of renewable fuels like wind and solar power, and the valiant efforts of states like California to sharply reduce their own emissions and lead where Mr. Trump will not.
The bottom line, according to the Global Carbon Project, is that after three years in which emissions remained largely flat, global levels of carbon dioxide increased by 1.6 percent in 2017 and are on pace to jump by 2.7 percent this year. Some scientists have likened the increase in emissions to a “speeding freight train.” That has a lot to do with economic growth. It also has a lot to do with not moving much faster to less carbon-intensive ways of powering that growth. Or in Mr. Trump’s case, moving in the opposite direction.

Makoma Lekalakala: ‘There should be no nuclear in climate financing’
https://www.dw.com/en/there-should-be-no-nuclear-in-climate-financing/a-46740978-14 Dec 18, Prize-winning South African activist Makoma Lekalakala’s successful legal battle to stop a secret nuclear power deal in her homeland won her international acclaim. She tells DW about defending the environment in court.
Makoma Lekalakala: My major campaigning issue, it’s mitigation against climate change and with a specific focus on electricity generation in the country [South Africa] — it’s almost 90 percent from coal. And we know that coal is a major contributor of greenhouse gas emissions, so our campaign has been for a just transition towards a low carbon development.
We’re demanding a greater investment in renewable energy technologies, particularly that we can have a decentralized electricity system where solar and wind would play a major role.
The technology, we need a lot of investment in that so that we can be able to eradicate energy poverty. Local people can have their own socially-owned and community-owned renewable energy projects and co-operatives so that they can have access to electricity.
For us to be able to do that, a just transition for us would mean phasing out coal electricity generation and having no nuclear at all as part of the energy mix, and having wind and solar being increased as part of our energy mix.
Our main mission is for me to ensure that, or to advocate that, there should be no nuclear in climate financing.
Why are you against nuclear power?
Earth Life is an anti-nuclear organization, because we believe that nuclear, it’s not safe. It’s an old technology that comes from the war era and it’s not even safe for us to be able to use for various reasons. It’s not economic, it’s quite expensive, it’s not safe, it’s quite dangerous.
We can remember all the accidents that have taken place, from Fukushima, from Three Mile Island, and nuclear also leaves a legacy of radioactiveness for hundreds and hundreds of years to come.
South Africa has got a principal policy on having an energy mix as part of the energy supply of the country. However, that legislation and regulations imply that if we have an energy mix we should also decide what kind of energy we would want to be part of the mix.
What we have in South Africa, which is written in the legislation, is that the energy choice should be least cost. That is having less externalized costs to the environment, to the atmosphere.
This is not the case around nuclear. And what we’ve seen is that the government also had flouted regulations and legislation by forcing some Africans to accept nuclear power.
Can you tell us more about your legal battle against the controversial secret nuclear power deal between South Africa and Russia?
In 2015 October, Earth Life Africa filed papers against the state president, against the Department of Energy, against the National Energy Regulator of South Africa, because we felt that these three institutions were supposed to be able to forward the information that was public information. It was suspected that the political elites in the country were actually the drivers of the nuclear deal.
We went to the court based on the legislative and regulatory processes in the country that were flouted, not followed, because all the other agreements were done in secret. That’s how the nuclear industry operates.
So we were vindicated that all the processes in the constitution, our regulations, were not followed at all in favor of the Russians to get to build or to construct the nuclear reactors.
One of the main issues why we opposed, or why we are opposing nuclear energy, is that we don’t want to turn our country, our continent and the world as a radioactive zone where life cannot exist.
What are the main environmental issues in South Africa?
The main environmental issue in South Africa, it’s pollution. As we speak now, South Africans, particularly in hotspot pollution areas, are unable to breathe. In Mpumalanga, where there’s almost about 11 coal-fired power stations and coal mines, this is an area that is very highly polluted and it’s one of the most polluted areas in the world.

Nuclear power is no answer to global heating – even if only because nuclear power is unaffordable
Want to solve climate problem? Nuclear isn’t the answer https://www.downtoearth.org.in/blog/energy/want-to-solve-climate-problem-nuclear-isn-t-the-answer-62428
Alternatives to nuclear energy, in particular renewable sources of electricity like wind and solar energy, have become drastically cheaper. By M V RamanaL 10 December 2018 “It is nuclear power that will be the main tool to reduce emissions” said Poland’s Minister of Energy, Krzysztof Tchórzewski, in keynote remarks at a meeting during the 24th Conference of Parties to the United Nations Framework Convention on Climate Change (COP 24) being held in Katowice, Poland. There is more than a little irony in that statement.
To start with, Poland, which is invested heavily in coal, has no nuclear power plants; its current plans call for starting nuclear power generation in 2030. That projection has to be taken with more than a pinch of salt. In 2002, even the International Atomic Energy Agency (IAEA), whose official objective is “to accelerate and enlarge the contribution of atomic energy”, concluded that nuclear power in Poland was not viable because of “insufficient economic competitiveness of nuclear plants, availability of cheaper alternatives and the absence of environmental motivation”.
The second irony was that Tchórzewski was speaking at an event organised by an initiative called Nuclear Innovation: Clean Energy Future, that was set up in May 2018 by the country that is withdrawing from the Paris climate accord, the United States of America. The United States, under the Trump administration, has been engaged in the perverse pursuit of various efforts that will result in increased emissions. Such an administration touting nuclear power suggests a basis for scepticism about nuclear energy being a tool to reduce emissions.
The final, and the most important, irony is that nuclear energy is fading in importance globally. The peak in nuclear power’s share of global electricity generation was 17.5 percent in 1996. Since then this fraction has steadily declined, reaching 10.3 percent in 2017. For a variety of reasons, the downward trend is expected to continue.
Although nuclear energy’s share of electricity generation has been continuously declining, expectations for how nuclear energy will fare in the future went up in the first decade of this millennium, thanks to propaganda from nuclear advocates about an impending nuclear renaissance. That supposed resurgence came to a crashing halt after multiple devastating accidents at the Fukushima Daiichi nuclear plant in Japan that started in 2011, which reminded the world about the hazardous technology involved in the generation of nuclear power. Even the IAEA’s average projections for nuclear power for the year 2050 have decreased from 1,002 gigawatts (GW) as laid out in 2010 to 552 GW in its 2018 publication.
This decline reflects the corresponding declines in future projections of nuclear power in many individual countries as exemplified by India and China. In 2010, the secretary of India’s Department of Atomic Energy (DAE) announced a target of 35 GW by 2020. The DAE is nowhere near that target and, as of December 2018, the current capacity is only 6.8 GW. If all the currently under-construction plants are ready in time, the total installed capacity will reach 13.5 GW by 2024-25, a far cry from earlier projections.
In China, the country constructing the largest number of nuclear plants, the official target as of 2010 was 70 GW by 2020, and the expectation was that “reaching 70GW before 2020 will not be a big problem”. That proved not to be the case and China’s current target for 2020 is only 58 GW and it is unlikely to meet that target.
India and China are often considered the poster children for nuclear energy growth—and even there the picture is quite dismal. The outlook in other countries is worse. Operating nuclear capacity in the two countries with the largest deployments of nuclear power plants, the United States and France, is expected to decline.
What is behind this trend? Fukushima is only a minor part of the story. The primary reason is that nuclear power is no longer financially viable. Because they are hugely expensive, it has been known for a while that building new nuclear power plants makes little economic sense. What has changed in the last decade is that it is not just constructing new reactors, but just operating one, even one that is old and has its capital costs paid off, that has ceased to make economic sense.
This is because alternatives to nuclear energy, in particular renewable sources of electricity like wind and solar energy, have become drastically cheaper. In contrast, just about every nuclear plant that was constructed in the last decade has proven more expensive than initially projected.
This economic reality adds to the other well-known problems associated with nuclear energy—the absence of any demonstrated solutions to managing radioactive waste in the long run, the linkage with nuclear weapons, and the potential for catastrophic accidents. The bottom line is that nuclear power cannot be a tool to decrease emissions. If we want to solve the climate problem, we will have to look elsewhere.
The drying of soils due to climate change is shrinking the world’s water supply
The long dry: why the world’s water supply is shrinking, EurekAlert, : 13-DEC-2018
Global water supplies are shrinking, even as rainfall is rising; the culprit? The drying of soils due to climate change
UNIVERSITY OF NEW SOUTH WALES A global study has found a paradox: our water supplies are shrinking at the same time as climate change is generating more intense rain. And the culprit is the drying of soils, say researchers, pointing to a world where drought-like conditions will become the new normal, especially in regions that are already dry.
The study – the most exhaustive global analysis of rainfall and rivers – was conducted by a team led by Professor Ashish Sharma at Australia’s University of New South Wales (UNSW) in Sydney. It relied on actual data from 43,000 rainfall stations and 5,300 river monitoring sites in 160 countries, instead of basing its findings on model simulations of a future climate, which can be uncertain and at times questionable
“This is something that has been missed,” said Sharma, an ARC Future Fellow at UNSW’s School of Civil and Environmental Engineering. “We expected rainfall to increase, since warmer air stores more moisture – and that is what climate models predicted too. What we did not expect is that, despite all the extra rain everywhere in the world, is that the large rivers are drying out.
“We believe the cause is the drying of soils in our catchments. Where once these were moist before a storm event – allowing excess rainfall to run-off into rivers – they are now drier and soak up more of the rain, so less water makes it as flow.
“Less water into our rivers means less water for cities and farms. And drier soils means farmers need more water to grow the same crops. Worse, this pattern is repeated all over the world, assuming serious proportions in places that were already dry. It is extremely concerning,” he added.
For every 100 raindrops that fall on land, only 36 drops are ‘blue water’ – the rainfall that enters lakes, rivers and aquifers – and therefore, all the water extracted for human needs. The remaining two thirds of rainfall is mostly retained as soil moisture – known as ‘green water’ – and used by the landscape and the ecosystem.
As warming temperatures cause more water to evaporate from soils, those dry soils are absorbing more of the rainfall when it does occur – leaving less ‘blue water’ for human use.
“It’s a double whammy,” said Sharma. “Less water is ending up where we can store it for later use. At the same time, more rain is overwhelming drainage infrastructure in towns and cities, leading to more urban flooding.”
Professor Mark Hoffman, UNSW’s Dean of Engineering, welcomed Sharma’s research and called for a global conversation about how to deal with this unfolding scenario, especially in Australia, which is already the driest inhabited continent (apart from Antarctica).
“It’s clear there’s no simple fix, so we need to start preparing for this,” he said. “Climate change keeps delivering us unpleasant surprises. Nevertheless, as engineers, our role is to identify the problem and develop solutions. Knowing the problem is often half the battle, and this study has definitely identified some major ones.”
The findings were made over the past four years, in research that appeared in Nature Geoscience, Geophysical Research Letters, Scientific Reports and, most recently, in the American Geophysical Union’s Water Resources Research………..
Sharma said the answer was not just more dams. “Re-engineering solutions are not simple, they have to be analysed on a region-by-region basis, looking at the costs and the benefits, looking at the change expected into the future, while also studying past projects so mistakes are not repeated. There are no silver bullets. Any large-scale re-engineering project will require significant investment, but the cost of inaction could be monstrous.”
In urban areas, the reverse will be needed: flooding is becoming more common and more intense. Global economic losses from flooding have risen from an average of $500 million a year in the 1980s to around $20 billion annually by 2010; by 2013, this rose to more than US$50 billion. The Intergovernmental Panel on Climate Change expects this to more than double in the next 20 years as extreme storms and rainfall intensify and growing numbers of people move into urban centres.
Adapting to this is possible, but will require large-scale re-engineering of many cities, says Sharma. “Tokyo used to get clobbered by floods every year, but they built a massive underground tank beneath the city that stores the floodwater, and releases it later. You never see floods there now.” https://www.eurekalert.org/pub_releases/2018-12/uons-tld121118.php
Global nuclear industry aggressively lobbying climate negotiators
NIRS (accessed) 10th Dec 2018 , The nuclear industry is aggressively lobbying global climate negotiators to promote nuclear power as a solution to the climate crisis. Pro-nuclear organizations are petitioning the United Nations COP24 Global Climate Summit in Katowice, Poland, to write nuclear power into the rulebook that will be used to implement the Paris Climate Treaty.http://org2.salsalabs.com/o/5502/p/dia/action4/common/public/?action_KEY=26593
The EU, Canada, New Zealand, and scores of developing countries to strengthen their climate change commitments
Climate change talks result in renewed pledge to cut emissions, EU, Canada, New Zealand and developing countries to keep global warming below 1.5C Guardian, Fiona Harvey, Ben Doherty and Jonathan Watts in Katowice, 13 Dec 2018
The promise, which follows increasingly dire scientific warnings, was the most positive message yet to come from the ongoing talks in Poland.
The announcement came at the end of a day in which the UN secretary general made an impassioned intervention to rescue the talks, which have been distracted by US, Russian and Saudi moves to downgrade scientific advice.
“We’re running out of time,” António Guterres told the plenary. “To waste this opportunity would compromise our last best chance to stop runaway climate change. It would not only be immoral, it would be suicidal.”
The talks have centred on devising a rulebook for implementing the 2015 Paris agreement and raising countries’ level of ambition to counter climate change, but progress has been slow on several key issues and divisions have emerged between four fossil fuel powers – the US, Russia, Saudi Arabia and Kuwait – and the rest of the world.
The UN believes China could play a stronger role in the absence of leadership from the US. Sources said Guterres would make a telephone call to Xi to ask for his help in nudging talks forward.
The EU also wants China, which is a key member of the block of 77 developing countries, to step up to ensure that countries all follow the same rules in being transparent over their greenhouse gas emissions.
Campaigners praised the decision by the High Ambition Coalition group of countries, made up of the EU and four other developed countries, including Canada and New Zealand, as well as the large grouping of least developed countries and several other developing nations, to scale up their emissions-cutting efforts in line with a 1.5C temperature rise limit.
Wendel Trio, director of the Climate Action Network Europe, said: “The spirit of Paris is back. The statement will boost greater ambition at the crunch time of these so far underwhelming talks. For the EU this must mean a commitment to significantly increase its 2030 target by 2020, even beyond the 55% reduction some member states and the European parliament are calling for. We call upon the countries that have not signed the statement so far to stop ignoring the science.”
Guterres, in a pointed criticism aimed at the four countries that have been refusing to “welcome” the Intergovernmental Panel on Climate Change’s special report on 1.5-degree warming, said rejecting climate science was indefensible.
He added: “The IPCC special report is a stark acknowledgment of what the consequences of global warming beyond 1.5 degrees will mean for billions of people around the world, especially those who call small island states home. This is not good news, but we cannot afford to ignore it.”
Frank Bainimarama, the prime minister of Fiji and the outgoing chair of COP23, amplified Guterres’ message. He told delegates they risked going down in history as “the generation that blew it – that sacrificed the health of our world and ultimately betrayed humanity because we didn’t have the courage and foresight to go beyond our short-term individual concerns: craven, irresponsible and selfish”.
The former US vice-president Al Gore told delegates they faced “the single most important moral choice in history of humanity”.
Behind the scenes, delegates said there had been strong progress on finance thanks to a doubling of commitments by Germany and Norway to help poorer nations adapt to climate change and build institutions capable of monitoring emissions. Nicholas Stern, the author of a landmark review on the economics of climate change, praised “the level of ideas and cooperation”.
But others said there were still many disputed brackets in the negotiating text on transparency and other elements of the rulebook……..
“The window for action is closing fast. We need to do more and we need to do it now,” said the document, which would form part of the official statement from this conference. https://www.theguardian.com/environment/2018/dec/12/un-chief-antonio-guterres-attempts-to-revive-flagging-climate-change-talks
Scientists warn about international inaction on climate change
Window is narrowing’: scientists urge action at UN climate talks, Guardian, Jonathan Watts in Katowice, Wed 12 Dec 2018Gilet jaunes protests cast shadow as concerns raised over backlash against rapid change Scientists have laid down the gauntlet for political leaders as the UN climate summit in Katowice, Poland, wrestles with the challenge of cutting emissions without sparking social tensions like those seen recently in France.The UN climate talks – known as COP24 and the most important since the Paris agreement was signed in 2015 – aim to set a new rulebook for governments to reduce greenhouse gases and to raise ambitions, after warnings of dire consequences if global warming rises more than 1.5C above pre-industrial levels.
The climate crisis is already here and the risks are growing, said Hoesung Lee, chair of the UN Intergovernmental Panel on Climate Change, who led a study by thousands of scientists on ways to avoid 1.5C of warming via accelerated transition from fossil fuels.
“The IPCC made a tremendous collective effort to bring you the best scientific knowledge on the subject. We tell you limiting warming to 1.5C is possible but the window is narrowing,” Lee told a plenary on Tuesday. “The scientific community has delivered, now it is up to governments to take action.”
There has been fierce debate about what to do with the study. All but four of the world’s governments want to formally welcome the 1.5C report to spur a more ambitious shift towards renewable energy. However, four oil producing nations – the US, Russia, Saudi Arabia and Kuwait – said the study should merely be “noted”.
This issue has overshadowed the past few days of the talks in Poland. Saudi Arabia has claimed there are “gaps and uncertainties” in the study. The US held a long-planned event promoting coal, gas, oil and nuclear power.
In a thinly veiled criticism of such tactics, Laurent Fabius, a former prime minister of France and president of the 2015 Paris climate talks, told the plenary that political leaders would play a negative role if they were “not only somnambulists but spoilers”.
He noted that global emissions rose by 2% this year, when they need to decline if warming is to be kept to a less dangerous level.
“Let us be clear, the real world is not on track. We need to do more and to do it faster,” Fabius said. “The IPCC 1.5C report shows the tremendous importance of every half degree and the disastrous consequences of missing that boundary.”……..https://www.theguardian.com/environment/2018/dec/11/the-window-is-narrowing-scientists-urge-action-at-un-climate-talks
