Global Warming Is Messing with the Jet Stream. That Means More Extreme Weather.
A new study links the buildup of greenhouse gas emissions to more frequent heat waves, floods and droughts in the Northern Hemisphere.
BY BOB BERWYN, INSIDE CLIMATE NEWS, 31 OCT 18 Greenhouse gases are increasingly disrupting the jet stream, a powerful river of winds that steers weather systems in the Northern Hemisphere. That’s causing more frequent summer droughts, floods and wildfires, a new study says.
The findings suggest that summers like 2018, when the jet stream drove extreme weather on an unprecedented scale across the Northern Hemisphere, will be 50 percent more frequent by the end of the century if emissions of carbon dioxide and other climate pollutants from industry, agriculture and the burning of fossil fuels continue at a high rate.
In a worst-case scenario, there could be a near-tripling of such extreme jet stream events, but other factors, like aerosol emissions, are a wild card, according to the research, published today in the journal Science Advances.
The study identifies how the faster warming of the Arctic twists the jet stream into an extreme pattern that leads to persistent heat and drought extremes in some regions, with flooding in other areas.
The researchers said they were surprised by how big a role other pollutants play in the jet stream’s behavior, especially aerosols—microscopic solid or liquid particles from industry, agriculture, volcanoes and plants. Aerosols have a cooling effect that partially counteracts the jet stream changes caused by greenhouse gases, said co-author Dim Comou, a climate and extreme weather researcher at the Potsdam Institute for Climate Impacts Research and the Vrije Universiteit Amsterdam.
“The aerosols forcing was a bit of a surprise to us,” Comou said. “Those emissions are expected to decrease rapidly in the mid-latitude regions in the next 10 to 30 years” because of phasing out of pollution to protect people from breathing unhealthy air.
In recent decades, aerosol pollution has actually been slowing down the global warming process across the Northern Hemisphere’s mid-latitude industrial regions. If aerosol emissions drop rapidly, as projected, these regions would warm faster.
That would change the temperature contrast between the Arctic and mid-latitudes, which would dampen the warming effect of greenhouse gases on the jet stream. By how much depends on the rate, location and timing of the reductions, and the offset would end by mid-century, when man-made aerosols are expected to be mostly gone and no longer reflecting incoming solar radiation, said Pennsylvania State University climate scientist and study lead author Michael Mann. ……….
The new study focuses on summer extremes, while other research has looked at how global warming affects the jet stream in winter.
What Happens in the Arctic Doesn’t Stay There
Daniel Swain, a climate scientist at UCLA and the National Center for Atmospheric Research who was not involved with the new research, said the study has some “compelling new evidence on the link between amplified Arctic warming and extreme mid-latitude weather during the summer months.”
What happens in the Arctic doesn’t stay there. Increased melting of reflective sea ice in summer exposes more dark-colored ocean to absorb heat, and that heats the surrounding land. As Arctic warming races ahead of the rest of the global average, the temperature contrasts that drive the jet stream are reduced, and the river of wind more frequently twists into sharp and slow-moving or stationary waves.
“When the jet stream enters this wavy state, extreme weather tends to occur on either side of the amplified ridges and troughs as the storm track becomes locked in place,” Swain said. Then, specific regions experience long periods of cool and stormy or, contrarily, hot and dry weather, he added. https://insideclimatenews.org/news/31102018/jet-stream-climate-change-study-extreme-weather-arctic-amplification-temperature

“Climate change, nuclear power, and the adaptation–mitigation dilemma” https://nuclearexhaust.wordpress.com/2018/11/04/climate-change-nuclear-power-and-the-adaptation-mitigation-dilemma/ Natalie Kopytko and JohnPerkins The University of York, Heslington, York YO10 5DD, UK The Evergreen State College, 1806 24th Avenue NW, Olympia, WA 98502, USA, Available online 30 October 2010.

Abstract
Many policy-makers view nuclear power as a mitigation for climate change. Efforts to mitigate and adapt to climate change, however, interact with existing and new nuclear power plants, and these installations must contend with dilemmas between adaptation and mitigation. This paper develops five criteria to assess the adaptation–mitigation dilemma on two major points:
(1) the ability of nuclear power to adapt to climate change and
(2) the potential for nuclear power operation to hinder climate change adaptation.
Sea level rise models for nine coastal sites in the United States, a review of US Nuclear Regulatory Commission documents, and reports from France’s nuclear regulatory agency provided insights into issues that have arisen from sea level rise, shoreline erosion, coastal storms, floods, and heat waves. Applying the criteria to inland and coastal nuclear power plants reveals several weaknesses.
Safety stands out as the primary concern at coastal locations, while inland locations encounter greater problems with interrupted operation. Adapting nuclear power to climate change entails either increased expenses for construction and operation or incurs significant costs to the environment and public health and welfare. Mere absence of greenhouse gas emissions is not sufficient to assess nuclear power as a mitigation for climate change.
Research Highlights
►The adaptation-mitigation criteria reveal nuclear power’s vulnerabilities. ►Climate change adaptation could become too costly at many sites. ►Nuclear power operation jeopardizes climate change adaptation. ►Extreme climate events pose a safety challenge. end quote of abstract. see original link above.

“This research comprehensively described the occurrence of extreme weather and climate events and aspects of sea level rise that are relevant from the view point of safety of nuclear power plants.
Studies about the frequency, intensity, and spatial and temporal variation of the extreme weather events and their combinations were carried out utilising instrumental meteorological observations, a 1 200-year long preindustrial control simulation and future climate model simulations.
In addition to the role of natural climate variability, the study clarified the influence of human-induced climate change on extreme weather events and sea level values. The longest future climate and sea level projections extend to the end of the 21st century.
According to them, the daily maximum temperatures and the length of the longest hot spells will clearly increase in Finland. The largest changes, however, are projected for the wintertime minimum temperatures. During summer there will be more intensive precipitation events and during winter more frequent precipitation days. The mean sea level is projected to rise, the change depending on the location along the Finnish coastline. Uncertainty ranges in the mean sea level scenarios are large mainly due to uncertainties in the future behaviour of the continental ice sheets.” end quote. Please see original link above.

New Documentary by ChomskySpeaks.org with Noam Chomsky Challenges Establishment over Twin Threats of Climate Change and Nuclear Annihilation https://www.prnewswire.com/news-releases/new-documentary-by-chomskyspeaksorg-with-noam-chomsky-challenges-establishment-over-twin-threats-of-climate-change-and-nuclear-annihilation-300743226.html
Renowned public intellectual calls out Democrats and Republicans for escalating nuclear dangers and decries Republican Party “dedicated to the destruction of life” NEWS PROVIDED BY
ChomskySpeaks.org
Nov 02, 2018 BOSTON, Nov. 2, 2018 /PRNewswire/ — Executive Producer Randall Wallace and Director Patrick Jerome launch the online documentary, “Noam Chomsky: Internationalism or Extinction” on the website: http://ChomskySpeaks.org. Based on a lecture by the public intellectual who is often described as the “most quoted living intellectual,” the documentary brings both the activist energy and desperate concerns of climate change and nuclear escalation that are causing mass extinctions.
Against these dire realities, Noam Chomsky surveys “the internationalism” of inter-state cooperation and social movements as solutions. He notes the complicity of both Democratic and Republican parties in escalating nuclear tensions and nuclear proliferation. At the same time, he condemns the Republican Party for profit-driven policies leading to climate-altering, carbon pollution. The documentary is a compelling and urgent warning explaining such ideas and tools as “the Anthropocene,” “the Doomsday Clock,” “species extinction,” “internationalism,” “denialism,” “non-proliferation,” “NATO expansion,” “climate accords,” and “climate debt” among many others.
Many non-partisan organizations collaborated in organizing the original lecture upon which the documentary is based; several also supported the production of the documentary as a starting point for further analysis. These included peace movement organizations in collaboration with the Boston-based movement-building center, encuentro5 (http://encuentro5.org) and the democracy movement’s Liberty Tree Foundation for the Democratic Revolution (http://LibertyTreeFoundation.org). The video adds to their efforts at expanding the public conversation about vital issues of the day. A grant from the Wallace Action Fund supported the documentary.
Chomsky concludes his lecture with sober reflection on the urgent challenges facing humanity: “The tasks ahead are daunting and they cannot be deferred.” Media Contact:

Independent 4th Nov 2018 , The Supreme Court has refused to halt a novel lawsuit filed by young
Americans that attempts to force the federal government to take action on
climate change, turning down a request from the Trump administration to
stop it before trial.
The suit, filed in 2015 by 21 young people who argue
that the failure of government leaders to combat climate change violates
their constitutional right to a clean environment, is before a federal
judge in Oregon. It had been delayed while the Supreme Court considered the
emergency request from the government.

The starting point of any serious discussion of climate change must be to recognize that it is not possible to limit global
warming to either 1.5 or 2°C in any “resource- and energy-intensive scenario” where economic growth continues in the usual fashion.
How the IPCC’s solutions for reversing the Earth’s warming encourage business as usual. Yes Magazine, M.V. RamanaRobert Jensen Nov 02, 2018 The Intergovernmental Panel on Climate Change’s special report released in October rightfully elicited much public commentary about global warming and its truly frightening impacts. But in those initial reactions, less attention was paid to the unnerving implications of the report’s suggested solutions, which encourage us to roll the dice on unproven technologies and double down on nuclear power.
Underlying the IPCC report’s claims is the belief that technological solutions can fix the climate problem. Yet these fixes don’t address the root cause of climate change……….
The report outlines four broad pathways to stay within that limit, all of which include large-scale deployment of various technological fixes to climate change. ………
The scariest of the four pathways outlined in the report is a “resource- and energy-intensive scenario in which economic growth and globalization lead to widespread adoption of greenhouse-gas-intensive lifestyles, including high demand for transportation fuels and livestock products.” In other words, business as usual in a world where the usual business leads to the edge of a cliff. What could justify such an approach? The belief that technology will save us.
These technologies would have to be deployed at massive scales.The amount of carbon dioxide that would have to be captured and stored (i.e., buried) is nearly 1,200 billion tons (gigatons). To put that in perspective, the report also states that “by the end of 2017, anthropogenic CO2 emissions since the preindustrial period are estimated to have reduced the total carbon budget for 1.5°C” by the rough equivalent of 2,200 gigatons of carbon dioxide—give or take 320 gigatons. So, within 80 years, an amount that is more than half of all the CO2 emitted over two and a half centuries will have to be captured and stored using a technology that has not been demonstrated.
Along with these futuristic technologies, a more familiar savior also comes to the rescue: nuclear power. In the report’s “energy-intensive scenario,” nuclear energy has to increase by a factor of around five. Wishful thinking about unproven technologies is easier to understand than the continued faith in the failed project of nuclear energy. Nuclear energy has been generating electricity since the 1950s, with more than 400 nuclear power plants operating in the world today—long enough for us to evaluate its ecological and economic costs, risks, and benefits.
Nuclear energy has been declining, not growing, as a share of the electricity market during the period that climate change has become recognized as an important problem. In 1997, when the Kyoto Protocol was signed, nuclear power’s share of global electricity generation was about 17 percent. Twenty years later, nuclear energy contributed barely 10 percent of global electricity production in 2017. This included a period when the nuclear industry was heralding a renaissance. The downward trend is expected to continue.
Despite governments subsidizing the technology in various ways over the decades, the economics of nuclear energy is a major problem: Nuclear reactors are expensive to construct, and prone to costing more than budgeted and taking longer to build than projected. The flagship projects in Europe—Olkiluoto (Finland) and Flamanville (France)—use the latest reactor design, the EPR (which stands for either European Pressurized Reactor or Evolutionary Power Reactor). In the United States, Vogtle (Georgia) and V. C. Summer (South Carolina) use the Advanced Passive (AP1000) reactor design. What they have in common is unexpected cost increases: Costs at V. C. Summer went up so high that the utility constructing the plant abandoned it after spending billions.
One would think that these trends would lead policymakers to abandon nuclear power, but faith that these failures can be resolved is fueling government and private investments in a new generation of reactor designs—advanced reactors, small modular reactors, and Generation IV reactors. On paper, these look great, just like the EPR and the AP1000. But there is no reason to believe these new designs will prove cheaper than current reactors—unless the designers, constructors, and regulators emphasize lowered costs over safety, which increases the risk of future Chernobyls and Fukushimas.
Back to the panel’s report. The models it uses do not deal with these problems of nuclear energy. They simply assume that nuclear reactors will be built. And because of the focus on CO2 emissions, they don’t highlight the accompanying problems such as increased quantities of radioactive waste that would have to be stored and isolated from human contact for hundreds of thousands of years.
The underlying cause here is “technological fundamentalism,” the belief that the increasing use of evermore sophisticated, high-energy, advanced technology can solve any problem, including those caused by the unintended consequences of earlier technologies. This Panglossian approach allows modelers to state the climate problem can be contained without giving up a social and political system that is founded on continued and endless economic growth.
This belief also allows for the idea that the business-as-usual approach can continue, and the solution is replacing coal, gas, and nuclear plants with solar panels, wind turbines, and batteries or other storage technologies. As supporters of the fossil fuel and nuclear industries like to point out, even these technologies have environmental and social impacts. To live sustainably on this planet—and despite what folks such as Elon Musk might promise, this is the only planet available for the vast majority of the world’s inhabitants—even these more benign technologies have to be limited in scale.
The alternative is obvious. The starting point of any serious discussion of climate change must be to recognize that it is not possible to limit global warming to either 1.5 or 2°C in any “resource- and energy-intensive scenario” where economic growth continues in the usual fashion. To put it more bluntly, one cannot resolve the climate problem under capitalism, which cannot survive without endless growth.
Arguments against capitalism are at least as old as capitalism itself. If one is honest about the implications of the latest report, climate change is providing another compelling argument for fundamental economic change. https://www.yesmagazine.org/planet/nuclear-power-will-not-save-us-from-climate-change-20181102

New UN Report Warns of Impending Catastrophe as World Warms, Glaciers Melt, DAHR JAMAIL, TRUTHOUT PART OF THE TRUTHOUT SERIES CLIMATE DISRUPTION DISPATCHES NOVEMBER 2, 2018
“One of the penalties of an ecological education is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen. An ecologist must either harden his shell and make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.” —Aldo Leopold, A Sand County Almanac
“………The biggest news in the corporate media regarding climate change since my last dispatch has been the
UN report stating that we have 12 years left to limit a full-on climate change catastrophe. To avoid this fate, we would need to spend those 12 years curbing global emissions dramatically. Essentially, there would need to be a government-mandated plan across the globe that would enable us to limit warming to 1.5 degrees centigrade (1.5°C) rather than the 2°C goal of the 2015 Paris climate talks. Eliminating that extra .5 of warming would save tens of millions of people from sea level rise inundation, and hundreds of millions from water scarcity and a myriad of other catastrophic impacts. Limiting warming to 1.5°C would, scientists have said, require a radical rethinking of virtually every facet of modern society, including an abandonment of our entire fossil-fuel based economy. However, currently, we are headed for at least a 3°C increase by 2100, with no mass government mobilization in sight.
Meanwhile, the warnings that the catastrophe is already upon us continue.
A recent study in a paper published August 31 in the journal Science warned that for each degree of rise in global temperature, insect-driven losses to the staple crops of rice, wheat and corn increase by 10-25 percent. Given we are already at 1.1°C warming, we are already seeing these losses, which are sure to increase. “In 2016, the United Nations estimated that at least 815 million people worldwide don’t get enough to eat,” the University of Washington Press wrote of the study. “Corn, rice and wheat are staple crops for about 4 billion people, and account for about two-thirds of the food energy intake, according to the UN Food and Agriculture Organization.”
At the same time, scientists are deeply concerned about the fact that non-pest insect numbers are declining rapidly. Bees, moths, butterflies, ladybugs and other insects are far less abundant, and scientists around the world warn that these insects are crucial to as much as 80 percent of all the food we eat. “You have total ecosystem collapse if you lose your insects,” University of Delaware entomologist Doug Tallamy told the AP. “How much worse can it get than that?”
Meanwhile, in the realm of sea level rise, things are irreversibly catastrophic. A recent study of Antarctic ice sheets shows them to be far more sensitive to temperature increases than previously believed. The study showed that when global temperatures were only slightly warmer than they are currently, sea levels were 20-30 feet higher than they are right now. “It doesn’t need to be a very big warming, as long as it stays 2 degrees warmer for a sufficient time, this is the end game,” David Wilson, a geologist at Imperial College London and one of the authors of the new research told The Washington Post.
Equally disturbingly, lakes in the Arctic are literally bubbling and hissing: They are releasing methane in large quantities as the ground underneath them thaws. Methane is a greenhouse gas 100 times more potent than carbon dioxide on a 10-year timescale, and the widespread release of methane was a key driver of the Permian Mass Extinction event which annihilated more than 90 percent of life on Earth.
Meanwhile, the Arctic sea ice is melting rapidly. Ice extent reached its annual minimum recently, which is normally when the ice would begin reforming rapidly, particularly right in the middle of the Arctic Ocean. Instead, the ice continued to decline.
To underscore how governments are not doing enough to mitigate climate change impacts, Brazil, a major greenhouse gas emitting country, recently elected right-wing extremist Jair Bolsonaro as president. To say he is anti-environment (in addition to homophobic, racist and sexist) would be a gross understatement. Known as the Trump of the Tropics, his plans include disempowering federal environmental agencies, opening up Indigenous reserves in the Amazon to mining and farming, and building hydroelectric dams in the rainforest, where deforestation, already at crisis levels, is set to explode.
EarthImpacts of human-caused climate disruption across the terrestrial plane are becoming increasingly stark………
WaterAs usual, climate change-induced disruptions are glaringly apparent in the watery realms of Earth…….

New UN Report Warns of Impending Catastrophe as World Warms, Glaciers Melt, DAHR JAMAIL, TRUTHOUT PART OF THE TRUTHOUT SERIES CLIMATE DISRUPTION DISPATCHES NOVEMBER 2, 2018 “………….Denial and Reality
In a recent interview, Donald Trump, who had called human-caused climate change “a Chinese hoax,” said it is real, “but I don’t know that it’s manmade.” He also said the climate will “change back again” — whatever that means.Meanwhile, the ongoing denialism continues unabated in his administration. Climate change information was removed from an important planning document for a national park in New England, with the rationale that it was deemed a “sensitive” topic.
The North Carolina government did not like the science about sea level rise, so literally passed a law banning policies based on such forecasts. The state, of course, is still recovering from flooding from Hurricane Florence.
Meanwhile, Trump’s EPA has abandoned restrictions against hydrofluorocarbons, a chemical that has been linked to climate change. OPEC announced it is predicting a massive increase in oil production over the next five years — enough so that it will offset CO2 reductions from electric cars. On that note, it was recently exposed that the state of Texas, already the leading emitter of greenhouse gasses in the US, has approved 43 petrochemical projects along the Gulf Coast since 2012 — projects that add millions of tons more of greenhouse gas pollution.
Stunningly, despite the terrifying weather events and dire predictions of what’s to come, it has come to light that the Trump administration is aware of and accepts a projected 7-degree rise in global temperatures by just 2100. This came out in a draft statement issued by the National Highway Traffic Safety Administration, which was written to justify Trump’s decision to freeze federal fuel-efficiency standards for cars and trucks built after 2020. “The amazing thing they’re saying is human activities are going to lead to this rise of carbon dioxide that is disastrous for the environment and society,” Michael MacCracken, who served as a senior scientist at the US Global Change Research Program from 1993 to 2002 told The Washington Post. “And then they’re saying they’re not going to do anything about it.”
The Trump administration’s stance on climate change is essentially that we’re doomed, so what’s the point in cutting greenhouse gas emissions?
With regard to the alarming UN climate report, the White House basically shrugged it off, claiming that emissions in the US have dropped since 2005. This is a true statement, but does not explain the reason for that, which is a historic shift away from coal-fired electricity and toward renewables and natural gas.
Fortunately, reality is striking back.
A group of 17 bipartisan state governors representing states that comprise half of the total US GDP has vowed to both fight climate change and fight Donald Trump on the issue. They recently pledged $1.4 billion to support electric cars and institute new policies geared toward reducing greenhouse gas emissions.
Stunningly, even Bloomberg, a business news outlet, is running stories with titles like “New Climate Debate: How to Adapt to the End of the World.”
And of course, the language coming out of the UN is a sign that the international community is beginning to understand the full weight of climate change’s implication.
Alas, this realization has not yet been met with the policy response it deserves. The author of a key UN report on the dangers of breaching the 1.5°C global warming limit recently said that the world is “nowhere near on track” to keep warming below even that already arbitrary level.https://truthout.org/articles/new-un-report-warns-of-impending-catastrophe-as-world-warms-glaciers-melt/

NuClear News, Nov 18 Tide Turns Against Nuclear http://www.no2nuclearpower.org.uk/wp/wp-content/uploads/2018/10/NuClearNewsNo112.pdf
Following the recent National Infrastructure Assessment which advised the Government not to build more than two new nuclear stations (about 6GW) (1) and the Committee on Climate Change (CCC) statement that “If new nuclear projects were not to come forward, it is likely that renewables would be able to be deployed on shorter timescales and at lower cost,” (2) we have now seen the International Panel on Climate Change (IPCC) report making some pretty disparaging remarks about nuclear power. Perhaps the tide is finally turning.
The IPCC latest findings tell a nightmarish tale—one much worse than in previous reports— surveying the climate-change impacts we’re already experiencing with one degree of warming, and the severity of the impacts to come once we surpass 1.5 degrees of warming. Ten million more people would be exposed to permanent inundation, and several hundred million more to “climate-related risks and susceptible to poverty.” Malaria and dengue fever will be more widespread, and crops like maize, rice, and wheat will have smaller and smaller yields— particularly in sub-Saharan Africa, Southeast Asia, and Central and South America. Security and economic growth will be that much more imperilled. “Robust scientific literature now shows that there are significant differences between 1.5 and 2 degrees,” Adelle Thomas, a geographer from the Bahamas and also one of the report’s lead authors, told the New Yorker. “The scientific consensus is really strong. It’s not just a political slogan: ‘1.5 to stay alive.’ It’s true.” (3)
But the IPCC report points out that “the transition from the energy system that would be needed to limit global warming to 1.5 ° C is underway in many sectors and regions of the world. The technical, social, economic and political feasibility of solar energy, wind energy, and electricity storage technologies has improved considerably in recent years, while nuclear energy and Carbon dioxide (CCS) storage in the electricity sector did not show the same improvements.”
Nuclear: too weak, too slow, too expensive and too risky The IPCC report continues saying the timeframe between the date of decision and the commissioning of nuclear power plants is between 10 and 19 years, and current deployment capacity is slowed by public concern about the risk of accidents and problems with nuclear waste. In addition, the IPCC notes, that “the costs of nuclear energy have increased over time in some developed nations, mainly because of the prevailing conditions, where increased investment risks in high-capital-intensive technologies have become important.” The theoretical benefits that nuclear energy could bring in the fight against climate change are therefore far too weak, too slow, too expensive and too risky. While the IPCC report requires us to quickly reduce emissions, it is not possible to choose the slowest and most expensive electric generation technology to deploy, as well as the dirtiest and riskiest. Nuclear power is disqualified from the race of the climatic fight. (4)
The IPCC report also says: “In spite of the industry’s overall safety track record, a non-negligible risk for accidents in nuclear power plants and waste treatment facilities remains. The long-term storage of nuclear waste is a politically fraught subject, with no large-scale long-term storage operational worldwide. Negative impacts from upsteam uranium mining and milling are comparable to those of coal, hence replacing fossil fuel combustion by nuclear power would be neutral in that aspect. Increased occurrence of childhood leukaemia in populations living within 5 No2NuclearPower nuClear news No.112, November 2018 3 km of nuclear power plants was identified by some studies, even though a direct causal relation to ionizing radiation could not be established and other studies could not confirm any correlation”.
An April 2018 report from the International Renewable Energy Agency (IRENA) shows, renewable energy and energy efficiency can, in combination, provide over 90% of the necessary energy-related CO2 emission reductions the world needs. Furthermore, this can happen using technologies that are safe, reliable, affordable and widely available. While different paths can mitigate climate change, renewables and energy efficiency provide the optimal pathway to deliver most of the emission cuts needed at the necessary speed. But renewable energy will need to be scaled up at least six times faster for the world to meet the decarbonisation and climate mitigation goals set out in the Paris Agreement.
The total share of renewable energy must rise from around 18% of total final energy consumption (in 2015) to around two-thirds by 2050. Over the same period, the share of renewables in the power sector would increase from around one-quarter to 85%, mostly through growth in solar and wind power generation. The energy intensity of the global economy will have to fall by about two-thirds, lowering energy demand in 2050 to slightly less than 2015 levels. This is achievable, despite significant population and economic growth, by substantially improving energy efficiency, the report finds. (6)
So what is the UK Government doing?
On 15th October the UK Government wrote a joint letter with the Welsh and Scottish governments to the Committee on Climate Change to seek updated advice on meeting the 1.5oC target. (7) Specifically, the governments asked the CCC to report on the date by which they should look to set a net zero target, as well as the range which UK greenhouse gas emissions reductions would need to be within, against 1990 levels, by 2050 as an appropriate contribution to the global goal of limiting global warming to “well below” 2oC above pre-industrial levels. It has also asked for the corresponding emissions range for a 1.5oC target. But the letter said carbon budgets already covering the period 2018-2032 were out of scope of the request.
The Intergovernmental Panel on Climate Change (IPCC) warned that limiting global warming to 1.5oC by the end of the century would require “rapid, far-reaching and unprecedented changes in all aspects of society”, and that the world is currently heading for a 3oC rise in temperature. (8)
The exclusion of the period from 2018 – 2032 led to protests from green groups and the opposition. Labour’s Energy Spokesperson, Alan Whitehead, called on the government to strengthen its review of the UK’s long term carbon targets and allow the Committee on Climate Change (CCC) to assess whether existing near-term carbon targets are compatible with keeping temperature increases below 1.5C. CCC chief executive Chris Stark admitted he was surprised the letter explicitly stated that “carbon budgets already set in legislation (Carbon Budgets 3-5 covering 2018-2032) are out of scope of this request”. (9
The Scottish Government has now written separately to the CCC changing its position, and saying the previous request “should not therefore prevent you from advising on all of Scotland’s targets.” (10) No2NuclearPower nuClear news No.112, November 2018 4
Devastating Critique of UK policies on renewables
Meanwhile the BBC’s File on Four programme aired an unprecedented critique of the UK government’s undermining of renewables. The government says it is committed to green energy – its recent ‘Clean Growth Strategy’ claims plans are in place to cut greenhouse gases by more than half of 1990 levels by 2030. And yet, research shows investment in green energy fell 56% last year, the biggest drop of any country – with policy change, subsidy cuts and ‘stop-start’ support from ministers being blamed. So, do Britain’s plans for a greener future add up? File on 4 takes to the road to find out. On a trip around the North East of England, Simon Cox asks why, when the offshore wind industry has grown, other cheap, renewable energies like onshore wind, solar power and now biofuels are struggling to survive. He examines whether changes in policy are hitting crucial investment, and if ambitious climate targets will really be met.
While offshore wind expands, it’s not the same story for onshore. Changes to planning laws mean it’s pretty impossible to build them in England and Wales. The CCC has warned of big gaps in the Government’s programme. We are going to need more onshore wind and solar to meet our targets. Gareth Miller of Cornwall Insight told the BBC that “to simply shut out the two undeniably cheapest technologies … from being built to their maximum capacity in the UK seems to be very, very strange indeed … There is a question of how serious the Government is when it says it wants to decarbonise the power sector at the lowest cost to the consumer in a world where they are currently shutting out the cheapest technologies to make that happen … I think we’ll see a significant slowdown if we haven’t already.”
In 2015 the tariff for generating solar electricity was slashed by two-thirds for homeowners and large solar farms. The domestic market has now gone back to the level it was at before the feedin tariff came in. A lot of very good companies have gone bust or shrunk. Next April the remaining tariff for exporting electricity to the grid will disappear – a further blow to investors in solar power – it will ruin the financial case for putting solar panels on your roof. It will be the final end of the domestic solar market in the UK. You are looking at thousands and thousands of job losses across the country. One recent survey found over 40% of UK solar installers are considering quitting the industry. To survive British companies have been forced to look overseas. Solar Century, for example, wouldn’t be able to survive if it was just reliant on the UK. Jeremy Leggett, founder of Solar Century says:
“If I needed any more persuading that we are dealing with hostile forces who basically over many years have taken every opportunity to set us back while promoting the cause of more expensive nuclear and more expensive shale gas then this is it … of all the things they have done to harm our industry over the years this is arguably the worst … the prize for the Government in a country desperate for jobs would have been to build a domestic industry – that is not going to happen because so many big British companies have been driven to bankruptcy.”
The opportunity to build a really healthy British solar industry has been lost.
Dr Gem Woods from Imperial College says: “We now know that even what seemed like an impossibly stretching target of reducing our greenhouse gas emissions by 80% by 2050 is not going to be anything like good enough. And so we have to think very fast (and do very fast) about what sort of systems that we need to be deploying over the next 5, 10 and 20 years – not the next 50 years. At the moment we have locked ourselves into a set of processes that in my view are really delaying meaningful implementation of the types of technologies and systems that will allow us and our children to have any kind of meaningfully good future.”

The Climate Implications of the Migrant Caravan, EcoWatch, Olivia Rosane, Oct. 29, 2018 The U.S. military will send as many as 5,000 troops to the country’s Southern border to meet thousands of refugees and migrants who are traveling north through Mexico from Central America, The Independent reported Monday.
The group of thousands grew out of 160 people who gathered at a bus stop in the crime-plagued Honduran city of San Pedro Sula on Oct. 12, BBC News explained. News of the plan spread on social media, and, by the next day, the group had reached 1,000 members.
The migrants are heading north for a variety of reasons, from unemployment to violence. But one of the underlying causes is climate change.
“Central America, in general, has had chronic impacts of climate change,” Oxfam Guatemala Country Director Ana María Mendez Libby told Earther.
That’s because of drought and irregular rainfall in something called the Dry Corridor, a region in the lowlands of Central America along the Pacific coast. Migration from Guatemala, Honduras and El Salvador has rapidly increased in the past 10 years, which coincides with a period of drought that has cost the three countries around 700,000 acres in corn and bean crops just this year.
A study led by the UN World Food Program found that the drought, rather than violence, was the driving factor causing people to leave the region to seek food and work elsewhere, National Geographic reported.
While scientists still don’t know how much the current drought, driven primarily by an increasingly erratic El Niño cycle, can be blamed on man-made climate change, experts with experience in the region know the current weather patterns are more extreme than in the past. ……… https://www.ecowatch.com/climate-implications-migrant-caravan-2616282125.html

Brazil elects Bolsonaro, who has threatened Amazon and global climate efforts Climate Home News, 29/10/2018,
Rightwing president-elect has pledged to open the rainforest to farming and industry, while slashing environmental protections and democratic rights By Megan Darby
Jair Bolsonaro is the next president of Brazil, sparking fears for the future of the Amazon rainforest and the global climate.
In Sunday’s run-off, the right-winger won 55% of the vote, beating Fernando Haddad of the Workers’ Party.
Bolsonaro has courted the mining and farming lobbies, pledging to roll back environmental protections and gut federal enforcement. Early in the campaign, he threatened to withdraw Brazil from the Paris Agreement, but backtracked last week after an outcry at home and abroad.
Scientists have warned his proposed policies will send deforestation soaring, predicting clearances the size of the UK each year within a decade. That would make it “all but impossible” for Brazil to meet its climate commitments, four experts wrote in Mongabay.
The authoritarian leader’s praise for dictatorship and hostile comments towards minorities and political activists have also raised concerns about democratic freedoms. …..
Bolsonaro’s victory is raising concerns abroad, including in Norway, a major funder of forest protection efforts in the Amazon. The Norwegian government rebuked the outgoing administration and slashed payments to the $1.1 billion Amazon Fund last year, over an uptick in deforestation rates.
Under Bolsonaro, the Brazilian government is expected to be less amenable to international influence. In his comments on the Paris Agreement, the president-elect has expressed that his main concern is preserving Brazilian sovereignty.
Norwegian environment minister Ola Elvestuen told Norway’s state broadcaster: “Brazil’s contribution to reducing deforestation in the Amazon has been one of the most important measures to curb climate change in the last decade… We want to continue the good cooperation with Brazil in the future too.”
Ines Luna, a campaigner with Rainforest Foundation Norway said: “Of course we are extremely worried that Brazil will change its climate policies.”….http://www.climatechangenews.com/2018/10/29/brazil-elects-bolsonaro-threatened-amazon-global-climate-efforts/

First study on climate change impact in Mediterranean https://www.eurekalert.org/pub_releases/2018-10/cuoh-fso102618.php, The first-ever study synthesizing risks posed by climate and environmental changes in the Mediterranean, CITY UNIVERSITY OF HONG KONG As the Mediterranean Basin is experiencing the impact of climate change more than ever, an international network of scientists has worked together to synthesize the effects of climate change and environmental problems, as well as the incurred risks, in the region, to facilitate decision-making in addressing the issues.This first-ever synthesis of multiple environmental changes and risks affecting the livelihoods of people in the entire region has just been published in the latest issue of Nature Climate Change.
The rates of climate change observed in the Mediterranean Basin exceed the global trends for most variables. The impact has further exacerbated the existing environmental problems caused by land use changes such as urbanization and agricultural intensification, increasing pollution and declining biodiversity.
Led by Professor Dr Wolfgang Cramer from the Mediterranean Institute for Biodiversity and Ecology, an international team of scientists has just published a review article in Nature Climate Change to address the current and future risks related to these changes, titled “Climate change and interconnected risks to sustainable development in the Mediterranean”.
Professor Michael Tsimplis from the School of Law at City University of Hong Kong who is part of the international team and has multidisciplinary background with research in oceanography and climate change said, “this paper suggests that the risks posed by climate change in the Mediterranean Sea were underestimated because each was only examined independently. But in reality, they are interconnected and interact with social and economic problems exacerbating their impacts. So they all have to be addressed at the same time and within the same financial constraints.”
The paper reviews the various environmental changes and the risks posed by these changes in the five major interconnected domains, namely water resources, ecosystems, food safety and security, health, and human security.
For an instance, average temperatures in this region have already risen by 1.4°C since the pre-industrial era, 0.4°C more than the global average. Even if future global warming is limited to 2°C, as prescribed by the Paris Agreement, summer rainfall is at risk to be reduced by 10 to 30% in some regions, thereby enhancing existing water shortages and decreasing agricultural productivity, particularly in southern countries.
Due to climate change alone, the irrigation demands in the region are projected to increase between 4 and 18% by the end of the century. Population growth may escalate these numbers furthers to 22-74%. Tourism development, new industries and urban sprawl may increase water pollution, too.
The acidification of sea water, increasing heatwaves in combination with drought and land-use change also affect the natural ecosystems, posing risks in biodiversity and fisheries.
Food production from agriculture and fisheries across the Mediterranean region is also changing due to the social, economic and environmental changes. Combined with the ongoing switch to more animal-based food production, southern countries are at risk to increase their dependence on trade.
Public health is impacted by multiple trends of change, through heat waves, pollution (higher risk of cardiovascular or respiratory diseases), and the increased spread of disease vectors (West Nile virus, Dengue, Chikungunya). In politically unstable countries, environmental change is an increasingly relevant factor for socio-economic risks, due to famines, migration and conflict. Human security will also be threatened due to extreme weather, such as a rise in sea level posing a higher risk of storm surges for people living in coastal areas in the region.
To facilitate decision-making in the face of these risks, the authors call for a pan-Mediterranean integrated risk assessment. Therefore, the Mediterranean Experts on Climate and Environmental Change (MedECC) network has been established, currently involving 400 scientific experts, supported by government agencies and other partners, to produce a full synthesis of risks and present it to decision makers for debate and approval.

Meteorologist expects severe drought and heavy rain events to worsen globally https://www.sciencedaily.com/releases/2018/10/181025141009.htm, October 25, 2018, University of Oklahoma
- Summary: Meteorologists expect severe drought and long-lasting rainfall events to worsen in the future. Researchers have determined how frequent, intense and long lasting these types of events will be in the future.
A University of Oklahoma meteorologist, Elinor R. Martin, expects severe drought and long-lasting rainfall events to worsen in the future. In Martin’s new study just published, she determines how frequent, intense and long lasting these types of events will be in the future. Martin looks at both severe drought and rain events, but it is the first time extended heavy rain events have been studied.
-
“In some places, there will be more frequent droughts, and other places can expect more frequent rainfall,” said Martin, professor in the School of Meteorology, OU College of Atmospheric and Geographic Sciences. “The Caribbean and Central America will have more extreme droughts and the north and northeast of North America can expect more extreme heavy rain events. Around the world, some places will see droughts and heavy rain events become more intense, longer lasting and more frequent. For the agriculture and related industries, this is particularly important.”
Globally, there are areas that will overall become wetter and areas that will become drier. When it gets warmer, the water builds up and it rains for long periods, but there will be longer periods between rain events and in places, it will become drier. Even regions that are projected to become drier overall, like the Southwest and South Central United States, are expected to see more severe, longer and frequent periods of heavy rain. Martin refers to the May 2015 rain event in Oklahoma and Texas as one example of what could be expected in the future.
-
“When it gets warmer, water vapor can build up in the atmosphere, so when it does rain it rains a lot and for long periods, but there will be longer periods between rain events so droughts will become worse.” said Martin. She points to a changing climate as the reason these events will worsen, and defines droughts and rain events by using a standardized rainfall index to compare events between regions and seasons. For this study, Martin used the same climate models as the Intergovernmental Panel on Climate Change.

EDF curbs Fessenheim 2 nuclear reactor output due to dry weather https://www.reuters.com/article/france-drought-nuclearpower/edf-curbs-fessenheim-2-nuclear-reactor-output-due-to-dry-weather-idUSL8N1X63FD
PARIS, Oct 26 (Reuters) – French utility EDF reduced output at its 900 megawatts (MW) Fessenheim 2 nuclear reactor on Friday as prolonged dry weather across west and central Europe has led to low water levels at the Rhine river which it uses to cool the reactor.
French grid operator RTE said EDF cut output at Fessenheim 2 by 130 MW due to environmental issues. EDF use water from the Rhine river as coolant for the plant, France’s oldest, which has two 900 MW reactors.
EDF could not be reached for comment on the situation.

Pilgrim to move nuclear waste to higher ground, http://www.patriotledger.com/news/20181026/pilgrim-to-move-nuclear-waste-to-higher-ground By Joe DiFazio
The Patriot Ledger PLYMOUTH — Officials at the Pilgrim Nuclear Power Station said they want to move nuclear waste at the site to higher ground over the next few years with an eye toward sea level rise.
Patrick O’Brien, spokesman for Entergy, the plant’s owner, said that the new proposed site will be located in what is now a parking lot 75 feet above sea level and 350 feet away from Rocky Hill Road. The site is 700 feet away from the closest point on the shoreline, O’Brien said.
Pilgrim is slated to be shut down by June 1. Entergy announced in August it plans to sell the station to Holtec International who will decommission the plant. O’Brien said the plan to move the waste was made in conjunction with Holtec.
O’Brien said that the proposed site was chosen as the best of three under consideration and that it was evaluated for nine regulatory and technical requirements. O’Brien saidEntergy will apply for the required permits and plans to begin construction on the new site before Pilgrim shuts down.
Nuclear Regulatory Commission spokesman Neil Sheehan said that the move doesn’t need approval from his agency, but it would monitor construction of the new site and movement of the spent nuclear fuel. The NRC will need to approve Pilgrim’s sale to Holtec.
