began a solo climate protest by striking from school in Sweden in August. But more than 20,000 students around the world have now joined her. The school strikes have spread to at least 270 towns and cities in countries across the world, including Australia, the United Kingdom, Belgium, the US and Japan.
“I will instead let them know change is coming whether they like it or not.” “Since our leaders are behaving like children, we will have to take the responsibility they should have taken long ago,” she said. “We have to understand what the older generation has dealt to us, what mess they have created that we have to clean up and live with. We have to make our voices heard.”
Thunberg said the rapid spread of school strikes for climate around the world was amazing. “It proves you are never too small to make a difference,” she said. Her protests was inspired by US school students who staged walk-outs to demand better gun controls in the wake of school shootings. But initially her classmates refused to join in: “I had to do it alone.”

More climate protests planned for Saturday as Australians back student activists
News.com.au December 8, 2018
Another mass student-led march will be held across Australia today following news Adani would self-fund its controversial coal mine in Queensland.
It comes after thousands of students copped criticism from politicians including Prime Minister Scott Morrison for skipping school last week to attend climate change rallies instead.
The rallies on Saturday will be to protest against the Adani coal mine and Jean said they were opposed to the use of coal for electricity and were also against the development because of the potential impact on the Great Barrier Reef.

U.S., Russia, Kuwait and Saudis block key climate study at COP24
Associated Press December 9, 2018
A diplomatic standoff over a key scientific study could set the stage for a bigger showdown during the second half of this year’s UN climate summit. Negotiators at COP24 took time out Sunday to rest after the first week of talks ended on a sour note the previous night, when the United States sided with Russia, Saudi Arabia and Kuwait in blocking endorsement of a landmark study on global warming.
“The United States was willing to note the report and express appreciation to the scientists who developed it, but not to welcome it, as that would denote endorsement of the report,” the U.S. State Department said in a statement. “As we have made clear in the IPCC and other bodies, the United States has not endorsed the findings of the report.”
Russia, Saudi Arabia and Kuwait also called for the study to be “noted” but not “welcomed.” While none of the four-oil exporting countries spelled it out, their objection to the report likely included its suggestion that fossil-fuel use needs to be phased out by 2050. Oil, gas and coal are major sources of carbon dioxide, which traps heat in the atmosphere.

Excellent, long article about “clean” coal…
U.S. clean coal program fails to deliver on promised smog cuts
Reuters December 3, 2018
But refined coal has a dirty secret. It regularly fails to deliver on its environmental promises, as electric giant Duke Energy Corp found.
Duke began using refined coal at two of its North Carolina power plants in August 2012. The decision let the company tap a lucrative federal subsidy designed to help the American coal industry reduce emissions of nitrogen oxides – also known as NOx, the main contributor to smog and acid rain – along with other pollutants.
In nearly three years of burning the treated coal, the Duke power plants collected several million dollars in federal subsidies. But the plants also pumped out more NOx, not less, according to data from the U.S. Environmental Protection Agency analyzed by Reuters.
The NOx emission rate at Duke’s Marshall Steam Station power plant in Sherrills Ford, North Carolina, for example, was between 33 percent and 76 percent higher in the three years from 2012 to 2014 than in 2011, the year before Marshall started burning refined coal, the EPA data shows.
As Study Ties ‘Great Dying’ of 252 Million Years Ago to Current Climate Crisis, Experts Say Still Time for ‘Different Path’
Common Dreams December 6, 2018
For the first time ever, researchers have tied “climate change triggered by volcanic greenhouse gases” to the largest extinction in Earth’s history, often called the “Great Dying,” 252 million years ago—and their findings, published Thursday by Science, are just the latest fuel added to the burning concern about the world’s current extinction crisis.
While scientists have long believed the volcanic activity was tied to the mass extinction, as United States Geological Survey geologist and volcanologist Seth Burgess put it, this new research “takes the next step in figuring out why things died at the end of the Permian… It couples what we think was happening in the climate with the fossil record, and it does it elegantly.”
The study determined that as ocean waters warmed and oxygen levels fell, marine animals suffocated and died out. “For the first time, we’ve got a whole lot of confidence that this is what happened,” Deutsch told the Guardian. “It’s a very strong argument that rising temperatures and oxygen depletion were to blame.”
“Voluminous emissions of carbon dioxide to the atmosphere, rapid global warming, and a decline in biodiversity—the storyline is modern, but the setting is ancient,” Penn State geosciences professor Lee Kump, who was not part of the research team, wrote in a Science piece responding to the new findings.
“As our understanding of the drivers and consequences of end-Permian climate change and mass extinction improves,” Kump added, “the lessons for the future become clear.”
Climate change could bring fatal asthma thunderstorms to Australia
News.com.au December 7, 2018
The review, published in the latest issue of Public Health Research & Practice, reviews international studies since 2000 relating to climate change, allergens and allergy. “Australia is highly vulnerable to any adverse impact of climate change on allergens and allergic diseases,” it says.
“This underlying vulnerability was highlighted in November 2016 when the world’s largest, most catastrophic epidemic thunderstorm asthma event occurred in Melbourne.”
Ten people died during or soon after a thunderstorm asthma event in Melbourne on November 21, 2016 which saw an unprecedented surge in demand for ambulances.
A combination of high pollen levels, strong winds, hot temperatures, air moisture and a cold front triggered severe asthma attacks.

Peak Oil Review
Resilience December 10, 2018
The OPEC+ Production Cut: The story of last week’s OPEC meeting seems to be one of concessions on the part of the Saudis who are taking by far the largest share of the cut while giving in to demands for exemptions by Iran, Libya, and Venezuela. Moscow stated its opposition to a reduction several times in the last few weeks, but in the end, agreed to a slow starting cut of 228,000 b/d. The Saudis were under pressure from President Trump who kept tweeting his opposition to any production cut that might drive prices higher. The Khashoggi affair and anti-Saudi bills floating around the US Congress are yet another aspect of the pressures the Saudis are facing. Following the meeting, Saudi energy minister Khalid al-Falih tried to calm Washington by saying “We try to keep the market within a reasonable band for consumers.” US Shale Oil Production: Unless the OPEC+ production cut results in a significant retracing of the nearly $25 a barrel drop in oil prices that has taken place in the past two months, next year may not be a good one for US shale oil producers. Oilfield service companies this year have been hit by a slowdown in demand as regional oil prices have fallen with transportation bottlenecks faced by producer customers.

Assorted Thoughts On Politics, Humanity, And The World
Caitlin Johnstone December 11, 2018
What’s coming up in a mere generation or so is one of three possibilities: total freedom, total slavery, or total annihilation. Sorry centrists, there is no incremental option. The confluence of AI, automation, and an increasingly paranoid and controlling elite class means that we are likely to be subjected to more surveillance, more manipulation, more work for less pay as jobs disappear along with safety nets, if we don’t destroy ourselves altogether.
It’s not that hard. We have all the tools we need already.
From mangoes to maize, climate change brings new hunger threats
Reuters December 9, 2018
In northern Ghana, where climate change is bringing an ever-shorter rainy season, struggling farmers are looking for more land they can plant to get enough of a harvest to feed their families.
That’s bad news for the region’s women, who cannot own land of their own but instead farm on plots men give them temporary permission to use, says Prince Ansah, a University of Ghana expert on adaptation to climate change.
“The vulnerable will have to give up the lands they have so other farmers can farm more,” he warned. “Women and minorities (and) migrants will be relegated in terms of some of those resources.”
“The Mayan holy book says we are made from corn,” she said. “Everywhere in Guatemala you find corn. It’s the basis of our food.”
But hotter and more extreme weather associated with climate change is making growing the crop much harder – presenting not just practical but cultural problems.
“If the corn crop is going to have difficulties, the Guatemalan people are going to have them too,” she said.
Canadian Government Declares Oil Trains Safe and Plans to Get Into the Oil Train Business
Desmog December 12, 2018
As Canadian oil-by-rail numbers reach record new volumes (and expected to rise), Canada’s Transportation Safety Board (TSB) announced recently that it would no longer list shipping the hazardous material by rail as a top safety concern.
Just a month later, the Alberta provincial government — where the majority of tar sands oil is produced — announced plans to bail out the tar sands industry by getting into the oil-by-rail business.
Here’s why that’s bad news for the communities in both Canada and the U.S. where this influx of oil train traffic will pass…
Trump’s EPA Says ‘Merry Christmas’ as It Guts Clean Water Rules for 1/3 of Americans
Grit Post December 11, 2018
In a move both announced and signed Tuesday, the EPA changed the definition of WOTUS (Waters of the United States) put in place by the Obama administration, which is how the agency defines what waterways fall under its jurisdiction and the jurisdiction of the Army Corps of Engineers.
Under the Obama EPA, the WOTUS policy expanded what waters were deemed important for conservation to include smaller bodies of water. But on Tuesday, EPA Administrator Andrew Wheeler reversed this entirely. This has dramatic potential ramifications for the safety of the nation’s tap water.
New important study on permafrost…
Permafrost Melt Could Destroy a Third of All Arctic Infrastructure, Affecting as Many as 4 Million People
Earther December 11, 2018
Rising temperatures are melting frozen soil at an alarming clip with the changes visible before our very eyes today. But the future promises an even more dramatic shift according to a new study published Tuesday in Nature Communications. As the frozen ground turns to muck, it could result in millions of people left without homes or the infrastructure that makes living in one of the harshest environments on Earth possible. What’s more disconcerting is that even if the world slashes carbon emissions dramatically, these changes are basically locked.
The new findings offer what the authors call “an unprecedentedly high spatial resolution” look at how the melt of frozen soil, known as permafrost, will impact infrastructure. As permafrost melts, it essentially turns previously firm ground into a slurry of soil and water. Communities in the Arctic are already coping with the impacts the 1 degree Celsius (1.8 degrees Fahrenheit) of warming since the industrial revolution has wrought. Infrastructure is collapsing or at risk of it as are traditional ways of life.
Inspections and pollution tests drop as Environment Agency sheds thousands of staff
Unearthed December 8, 2018
The EA has shed the equivalent of more than 2,500 full time jobs (20% of its workforce) since 2013. In a statement, minister for the Department of Environment, Food and Rural Affairs (Defra) George Eustice said nearly 1,000 EA staff – all of which were in corporate services such as finance, HR and IT – have been transferred to the department to help it handle the Brexit workload.
Unearthed analysis of official statistics shows that, over the same time period, the agency has sharply scaled back on key duties, including inspections of permitted industrial sites and farms, water pollution sampling, and legal actions against polluters.
Cost of Carbon Capture Just Got Lower Thanks to New Tech
Green Optimist December 8, 2018
Carbon dioxide removal (CDR) technologies aim to remove CO2 directly from the atmosphere. To that end, artificial photosynthesis refers to the CO2 fixation reaction which converts CO2 to sugar and other organic compounds using metal-complex photocatalytic systems. On the other hand, carbon capture, utilization, and sequestration (CCUS) extracts carbon dioxide from industrial exhausts, preventing its release.
A combination of ceramic nano-filters and powerful fans are used to filter CO2 from emitted gases. Captured carbon is compressed and liquefied and then it is either transported to be used in other industrial processes or it is stored underground in depleted oil/gas fields or saline formations.

Rural Jobs: A Big Reason Midwest Should Love Clean Energy
Inside Climate December 7, 2018
The number of clean energy jobs is growing across the Midwest, and those gains are helping rural areas, according to a report issued today by the Natural Resources Defense Council.
The majority of clean energy jobs in all 12 Midwestern states are in energy efficiency, the report says. That includes building design, energy efficiency upgrades and other aspects of reducing energy use that save people money on energy costs while also reducing the greenhouse gas emissions that are warming the planet, triggering climate changes that put Midwestern farms at risk.
World’s first industrial facility to recycle diapers and sanitary napkins in Italy
Green Optimist December 9, 2108
Diapers and sanitary napkins are widely used, take half a million years to decompose and, at least until now, they end up in landfill. For example, each baby uses an average of 6000 diapers in their lifetime, and 1.3 million tonnes of feminine hygiene products per year are disposed only in North America. In Italy alone, 900.000 tonnes of diaper end up each year in landfill.
Maersk Pushes the Net Zero Carbon Emissions Envelope
Triple Pundit December 7, 2018
The global shipping company A.P. Moller – Maersk has joined the growing list of top corporations pledging either 100 percent renewable energy or net zero carbon emissions. That’s a fairly straight forward task for some companies, but it in the global transportation sector the obstacles seem insurmountable. After all, carbon is the lifeblood of shipping and logistics.
Renewable energy and net zero are two complementary but distinct goals. For example, a net zero pledge can simply mean that a company is using offsets to counterbalance its carbon emissions, rather than making operational changes that shrink its carbon footprint.
Maersk already has its own fleet of more than 50 engineers working on efficiency improvements, partly in response to air quality initiatives at the Port of Los Angeles and elsewhere. If all goes according to plan, 2019 will see that in-house effort expand into an industrywide collaboration
South Cambridgeshire council vows to reduce carbon emissions to zero
UN News December 10, 2018
“The point I’m trying to make is that the biggest industrial market and financial opportunity of the century is in transforming the old devices, systems and infrastructures which are inefficient and polluting, into efficient and clean and much more profitable industrial processes, devices, systems, technologies and solutions,” Mr. Piccard told UN News in an interview at COP24.
From solutions which make homes carbon-neutral, to developing cleaner cooling systems, or producing stainless steel more efficiently and more economically, the pioneer hopes the initiative will help make the case that climate action can happen now. He said it should not have to wait until 2050, and can be about “winning, not losing” – something he believes to be particularly critical for the poorer and more remote communities across the world, which are often dependent on others for all their energy needs.
Activists launch Spokane Community Adaptation Project
Lewiston Tribune December 7, 2018
Yet in Spokane and the region, some groups are trying to get involved. “People would be happy to learn how much adaptation is going on across the state, because people don’t tend to know that,” said Amy Snover, director of the University of Washington’s Climate Impacts Group. “It’s the tip of the iceberg. It’s nowhere near enough. But there are good people working on this.”
The goal is to take climate data and look at the various ways it will impact Spokane, Peterson said. Then, using that information, the group will make policy recommendations and provide information to individuals and businesses.
Participatory Development: A Humanitarian Alternative to Migration
Global Research December 11, 2018
Climate change, development and migration are part of an inextricably linked nexus. The Environmental Justice Foundation predicts that up to 10% of the world’s population could be at risk of forced displacement due to climatic hazards by 2050. At the GFMD conference, the EuroMedA Foundation, who hosted a side event entitled “ A Euro-African Approach to Migration” highlighted that key issues set to face Africa will be desertification, drought and food insecurity, risks that are only going to worsen. Climate change can also compound existing, or create new political and economic issues in at-risk countries and further drive migratory patterns, with the distinct possibility of turning plans for “Safe, Orderly and Regular Migration” on its head.
many migrants prefer not to be migrants, but instead seek the sustainable development of their origin communities. Involving local community members in the decision-making processes reveals key contextual insights into the priority initiatives that will enhance the wellbeing of their communities: these are highly viable and implementable because the projects respond to their self-defined needs, and are therefore most likely to be sustainable.
More states opt to phase out oil production
Climate News Network November 29, 2018
A growing number of governments are choosing to phase out oil production, reasoning that cutting the availability of fossil fuels can help to cut the demand for them.
They say phasing out oil production could be the next big step in climate policy, thanks to an initial group of first-movers who’ve already taken the plunge.
One is Spain, which announced this month that it plans to completely decarbonise its electricity system by mid-century, a move which includes a total ban on all oil and gas exploration.

VW says it’s investing about €1.2 billion in altering production facilities at Zwickau, where more than 7,500 people are employed. The company is also creating electric car plants elsewhere, including two in China – one near Shanghai and the other at Foshan in the south of the country.
Several other major car manufacturers have announced similar plans to ramp up electric vehicle production.
Net-Zero Energy Homes Pay Off Faster Than You Think—Even in Chilly Midwest Inside Climate News December 10, 2018
Net-zero-energy homes—homes that are so efficient a few rooftop solar panels can produce all the electricity the home needs—can be built almost anywhere, even in places with brutal winters.
The costs and benefits of building net-zero houses vary widely in major cities, ranging from San Francisco, where the benefits would cover the costs in eight years, to Philadelphia, where it would take about three times as long.

Climate players: Animals can swing a landscape’s capacity to store carbon
PHYS ORG December 6, 2018
Advances in remote sensing technologies are helping scientists to better measure how global landscapes—from forests to savanna—are able to store carbon, a critical insight as they evaluate the potential role of ecosystems in mitigating climate change.
the very presence of wild animals can trigger direct or indirect feedback effects that alter a landscape’s capacity to absorb, release, or transport carbon. In reviewing a growing body of research, they find that animals can increase or decrease rates of biogeochemical processes by 15 to 250 percent or more.
But the presence of grazing herbivores in other places—such as caribou and muskox in the Arctic or moose in boreal forests—can cause a 15 to 70 percent decrease in CO2 uptake and storage.
Could algae that are ‘poor-providers’ help corals come back after bleaching?
PHYS ORG December 6, 2018
reef-building is only possible because of a mutually beneficial relationship between the coral and various species of single-celled algae called dinoflagellates that live inside the cells of coral polyps.
The algae are photosynthetic—meaning capable of converting the Sun’s energy into chemical energy for food, just like plants. And the exchange of nutrients between the coral and the algae is essential for healthy reef communities. The coral provides the algae with carbon dioxide, nitrogen, and other compounds that they need to survive and perform photosynthesis. The algae, in turn, can stimulate the growth of the coral by providing them with sugars and fats, which are created via photosynthesis.
“We’re very interested in what happens when external conditions force corals to switch from hosting one symbiotic algal species to another,” Grossman said. “Having a long-term symbiotic relationship with a native algal species is advantageous to the coral. But if the surrounding conditions are altered by climate change, could a different algal species confer corals with improved fitness and chances of survival?”
Better land use could slash US emissions
Climate News Network December 7, 2018
What they identify as 21 natural climate solutions – better use of croplands, the restoration of forests and tidal wetlands, slowing the felling of timber and the containment of urban sprawl – could help limit global warming, slow climate change and reduce sea level rise for the nation that has over the last century emitted more greenhouse gas than any other country.
The most effective single action in a study launched by the US Nature Conservancy and 21 other institutions, and published in the journal Science Advances, would be to step up reforestation: this alone could absorb the emissions of 65 million passenger cars.
‘It’s a sad reality’: a troubling trend sees a 97% decline in monarch butterflies
The Guardian December 7, 2018
In the 1980s, roughly 4.5 million monarchs wintered in California, but at last count, there may be as few as 30,000
The shoreline would, not so long ago, be teeming with monarch butterflies at this time of year.
Boughs would be bent under the weight of black and orange clusters, as hundreds of thousands of the magical invertebrates nestled into the leaves, waiting out the frost on the California coast before returning north.
Mother Jones December 11, 2018
In an internal memo circulated within the Interior Department earlier this year, government scientists issued a stark warning: The Trump administration’s plans to allow oil exploration in Alaska’s Arctic National Wildlife Refuge (ANWR) could further jeopardize the region’s already fragile polar bear population. The document, authored in September by the head of the state’s US Fish and Wildlife Service office, noted that the threat posed to the bears could make it legally challenging for the agency to authorize a series of seismic surveys of the area’s petroleum reserves—even if steps were taken to mitigate the project’s environmental impact.
‘Off the Charts’: New Study Shows Greenland Ice Sheet Likely Hasn’t Melted This Fast for More Than 7,000 Years
Common Dreams December 6, 2018
“What we found with our ice cores is that it’s melting today more than at any time within at least the last three and a half centuries,” he said, “and probably, melting more today than any time in the last seven to eight thousand years.”
Trusel’s team of international researchers analyzed ice cores extracted from Greenland, a massive island wedged between the Arctic and Atlantic Oceans. A primary takeaway from the study, Trusel said in a statement, is the speed of melting, especially over the past 25 years.
“It’s not just increasing, it’s accelerating,” he explained. “That’s a key concern for the future.”
Why Energy Researchers Are Interested in a Tiny Wood-Eating Pest You’ve Never Heard Of
Climate Desk December 6, 2018
So, using gribbles from the southern English coasts of Portsmouth and the Isle of Wight, the team homed in on the “hind gut,” and observed how proteins called hemocyanins break down lignin, the near-impermeable polyphenol coating surrounding those coveted wood sugars. Besser calls the process a “pretreatment” for digestion. In other words, we knew that gribbles feed on potential biofuels, we just didn’t know how they unlocked them. It’s a simple process of oxidation, something hemocyanins are well practiced in. In order to carry oxygen through the gribbles’ tiny bodies, the hemocyanins bind to it with copper atoms, turning the invertebrates’ blood blue (compared to red blood, which gets its color from a reaction between oxygen and iron).
Using gribbles as a model to extract biofuels from wood could prove a game-changer in the quest to turn to alternative energy sources, and not only because the process is cleaner and cheaper than existing industrial techniques. “Woody plant biomass,” the team explains in a release, “is the most abundant renewable carbon resource on the planet …”
Detergent-like Molecule Recycles Itself in Atmosphere
NASA December 8, 2018
The hydroxyl (OH) radical—a molecule made up of one hydrogen atom and one oxygen atom with a free (unpaired) electron—is one of the most reactive gases in the atmosphere. It acts like a detergent in the air, breaking down other gases. In particular, OH is the main check on the concentration of methane, a potent greenhouse gas that is second only to carbon dioxide in contributing to global warming.
New research led by a postdoctoral fellow at NASA has shown that hydroxyl radicals are recycling themselves and maintaining a steady atmospheric concentration even in the face of rising methane emissions.
UK’s summer heatwave ’30 times more likely’ because of climate change

New analysis from the Met Office has found that the record-breaking summer temperatures were about 30 times more likely as a result of climate change caused by human activities.
The UK now has around a 12% chance of summer average temperatures being as high as they were in 2018, whereas they would have less than 0.5% chance of happening in a “natural” climate, the Met Office said.

Greenland ice loss quickening
PHYS ORG December 7, 2018
Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.
The research, published in Earth and Planetary Science Letters, uses radar altimetry data gathered by the ERS, Envisat and CryoSat missions between 1992 and 2016.
Radar altimeters record the height of the surface topography along the satellite’s ground track. They precisely measure the height of ice, water and land by timing the interval between the transmission and reception of very short radar pulses.
“Over the full 25-year period, the general picture shows much larger volume losses are experienced in west, northwest and southeast basins of Greenland compared to the more steady-state situations in the colder far north.”
Rules to boost fuel economy for vehicles will do more good than harm, new study shows
PHYS ORG December 6, 2018
Scholars from USC and other leading universities conclude that rules on the books to increase fuel economy for passenger vehicles will do more good than harm, contradicting claims by the Trump administration as it seeks to roll back fuel economy standards.
But the new study goes a step further, suggesting the shortcomings in the government’s economic analysis are so egregious they seem like a deliberate attempt to manipulate statistics and mislead people.
First, the scientists say the economic analysis mistakenly concludes that relaxation of the rule will shrink the vehicle fleet by 6 million cars by 2029, which greatly skews the bottom line. It also flies in the face of economic principles because, the economists argue, only more stringent standards—not fewer—would increase costs for cleaner, new vehicles, and as prices for new and used vehicles increase, fleet size would diminish—not the other way around. The revision “is simply inconsistent with basic economic theory,” the study finds.
Paul Beckwith: “I declare a global climate change emergency to claw back up the rock face to attempt to regain system stability, or face an untenable calamity of biblical proportions.”
Kevin Hester: “There is no past analogue for the rapidity of what we are baring witness to. There has been a flood of articles … 2C is no longer attainable and that we are heading for dangerous climate change”
Guy McPherson: “The recent and near-future rises in temperature are occurring and will occur at least an order of magnitude faster than the worst of all prior Mass Extinctions. Habitat for human animals is disappearing throughout the world, and abrupt climate change has barely begun.”
