Heidi Steltzer’s job, as she puts it, is “hiking where no one else will go.” 

As a mountain and polar ecologist studying rare plants, she’s accustomed to traveling to breathtaking Arctic vistas to chase flora along mountain ridges.
But watching glaciers calve on her first trip to Antarctica last December was a one-of-a-kind experience for the scientist. “You kind of want to see it,” she said.

 “Even though you know it’s not a good thing, you kind of want to be there.”
As she watched the great icebergs float by the boat in Neko Harbor, another member of Steltzer’s trip waved her arm at the scene, as if summoning a force to shave the glaciers surrounding them.
“Can you imagine if any one of us had that kind of power to see ice calve when you wanted to see it?” laughed Steltzer. “But at the same time, we knew, collectively — we do have that power. 

You can’t say these specific glaciers are definitively calving because of human action.

 But these events continuing to happen is consistent in that system, and consistent with what we know about human activity and climate change.”

Steltzer’s colleagues were more knowledgeable than your average gaggle of tourists. 

The travelers on her trip were all scientists, and several of them focus specifically on climate change.

 What’s more, her 75 companions on the three-week trip were all women, bound together on the largest-ever, all-female expedition to Antarctica. 

The trip was the focal point of a year-long leadership development program called Homeward Bound, which aims to groom 1,000 women with science backgrounds over the next ten years to influence public policy and dialogue.
While women made up more than 50 percent of the US workforce in 2016, they represented only 24 percent of workers in STEM — science, technology, engineering, and math. 

Representation in public policy is even worse: Women hold less than 23 percent of parliamentary positions worldwide, and less than 20 percent of Congress is female. 

The founder of Homeward Bound told Reuters that inspiration came from the trip from hearing two scientists joke that a beard was a requirement to land an Antarctic research leadership role.

The problem of female leadership in STEM isn’t a new one. When Katharine Hayhoe, director of the Climate Science Center at Texas Tech University and a leading U.S. climate voice, was a second-year undergraduate physics student, the head of the department called her into his office to ask how the program could help encourage her career as a female physicist.
“My mentors in science from day one have all been male,” she recalled. “I’ve learned a lot from them and I’ve been incredibly encouraged and supported by them. But at the same time, there have been differences between us.”

Lifestyle and family changes, Hayhoe emphasized, provide a particular sticking point between the genders in STEM. “As I got older, I started to realize how big the gap was between colleagues who basically had a spouse who managed everything full time,” she said. “They could just, at the drop of the hat, leap on an airplane and be off to a meeting, versus a mother who, before you do anything, you’ve got to do all the laundry, freeze the meals, figure out who is picking the kids up from schools. At this point, if someone asks me to do something at the drop of the hat, the answer is no — and this still happens to me today.”
Steltzer echoed similar experiences. “At one point in time, women were present in equal measures to myself at a peer level,” she said. “But now that I’m in my early 40s, an associate professor, in many environments I’m in there are fewer women. There are ways we can do better.”

She pointed out that the perception of “good old boys’ clubs” in male-dominated fields may just be men connecting with each other over shared experiences. Getting a group of female scientists together can create a collaborative, experience-based atmosphere that can be difficult for women to find at home. “Homeward Bound created for us women a space and a place where we feel connected to one another.”
For Anne Christianson, a younger Homeward Bounder, the trip took on special importance for her work. Christianson is completing a Ph.D. at the University of Minnesota, and her dissertation focuses on how climate change disproportionately affects women in developing countries. She points out that, while it was easy to see the consequences of climate change watching glaciers in Antarctica, it’s important to keep in mind how climate change threatens women around the globe.
“We have these cascading impacts [of climate change] on women that simply aren’t seen in men,” Christianson said. “Women generally don’t have enough capital to build our own resilience to climate change.”

The Crazy Climate Technofix #auspol 

by Mark White
Illustrations by Bren Luke 
Earth’s climate has been edging towards a scene usually reserved for a post-apocalyptic movie.

 Some posit geoengineering as a radical fix to climate change.

 Others say the risks are too high and its proponents mad. 

Welcome to the debate where science fiction meets climate science.

If you visit a block of land near the West Australian dairy town of Harvey in a few years’ time, you will see a few pipes sticking out of the ground, a solar panel and an aerial for communications devices. 

There may be a hut and some room for parking.
These will be the only visible signs of the South West Hub project, designed to test the feasibility of pumping megatonnes of carbon dioxide into the vast Wonnerup sandstone layer, a kilometre-and-a-half deep beneath the Jarrah-Marri trees on the surface.
The gas will be liquefied in a nearby compressor building – an anonymous farm shed – and transported to the injection site via underground pipes.
Wonnerup is an example of carbon capture and storage, one of a suite of technologies known as geoengineering, or climate engineering.
Geoengineering is a mixed bag, but the idea involves large-scale interventions at the level of the whole planet, with the goal of fixing the climate.

 It’s tricky, dangerous, and largely considered “fringe science”.
The proposals come in two main flavours. 

One is carbon dioxide removal, which strips the gas from the atmosphere and slowly restores atmospheric balance.

 A mix of techniques would be needed: hundreds of factories like Wonnerup, billions of new trees and plants, plus contentious technologies such as artificially encouraging the growth of plankton.
The second is solar radiation management, intended to cool the Earth by stopping the sun’s heat from reaching the planet’s surface. 

That can be achieved by pumping minute particles into the atmosphere, but carries the risk of killing billions of people.
Right now, we don’t have the tools or the knowledge to deploy these fixes. 

But some prominent climate scientists argue that as carbon emissions continue to rise, geoengineering will have to be employed to avoid catastrophic climate change.
 

Last December’s meeting of world leaders in Paris produced a voluntary agreement to try to limit the global temperature increase to 1.5C over pre-industrial levels, and to not exceed 2C – the widely agreed level of devastating heat increase.

 But agreement and actual efforts didn’t seem to go hand in hand.

“The roar of devastating global storms has now drowned the false cheer from Paris,” a team of 11 climate scientists wrote in a January letter to The Independent, “and brutally brought into focus the extent of our failure to address climate change. 

The unfortunate truth is that things are going to get much worse.”
University of Cambridge Professor Peter Wadhams says: “Other things being equal, I’m not a great fan of geoengineering, but I think it absolutely necessary given the situation we’re in. 

It’s a sticking plaster solution. 

But you need it, because looking at the world, nobody’s instantly changing their pattern of life.”
Since then, temperatures have been soaring month after month, we’ve learned that the Great Barrier Reef is in extremely poor health and bleaching rapidly, while new quests continue to unearth more fossil fuels.
As we’re failing to keep the planet pleasant and habitable for future generations, could we instead fix the climate with technology? 
With geoengineering?
Debate about geoengineering in Australia is “almost being avoided”, according to Professor David Karoly, a noted atmospheric scientist at the University of Melbourne.

 He is a member of the Climate Change Authority, which advises the federal government, and was involved in preparing the 2007 IPCC report on global warming.
“There’s very little discussion on it in terms of government circles, there’s very little research on it, there’s very little discussion of it in what might be called mainstream science,” Professor Karoly says.

Policymakers are including geoengineering in their plans, but many technologies are still unproven and potentially dangerous.
“You’ll generally find among climate scientists that almost all are opposed to geoengineering,” says Professor Jim Falk, of the University of Melbourne’s Sustainable Society Institute. 

“They’re already pretty concerned about what we’ve done to the climate and don’t want to start stuffing around doing other things we only half-understand on a grand scale.”
When the US National Academy of Science launched a report last year analysing geoengineering options, committee head Marcia McNutt, a geophysicist, was asked if any should be deployed. 

She replied “Gosh, I hope not”.
The report considered carbon dioxide removal and solar radiation management so risky it used the term “climate intervention” instead of geoengineering, arguing the term “engineering” implied a level of control that doesn’t exist.
But the IPCC has considered scenarios where such engineering would be necessary: its 2014 assessment report mentions bio-energy carbon capture and storage (known as BECCS), where plant fuel is burned and the resulting carbon dioxide buried.
And the Paris Agreement noted there would be need for a “balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases” in 2050-2100.
“A few years ago, these exotic Dr Strangelove options were discussed only as last-ditch contingencies,” wrote Kevin Anderson, deputy director of the UK’s Tyndall Centre for Climate Change, of the Paris talks in Nature magazine.
“Now they are Plan A.”
 

The term “geoengineering” raises the spectre of a James Bond villain cackling in his lair and planning to make volcanoes erupt at the push of a button. And that’s quite fitting, given that one approach to solar radiation management consists of mimicking the fallout from such giant explosions.
Treating the problem like an outlandish movie script may be the only way of comprehending the scale of the challenge. To reduce atmospheric CO2 levels by 1ppm – approaching the volume needed to stabilise global temperature – requires the withdrawal of 18 gigatonnes of gas, the equivalent of 18,000 South West Hub plants running for a year.
Tim Flannery, the former Australian of the Year who helped raise the profile of climate change, is vocal in supporting some geoengineering approaches. He prefers the less-toxic term “Third Way technologies”, based on the Earth’s natural processes.
Flannery says those which work at the gigatonne scale – the only ones which will dent the problem – may take decades to be developed.
“The only way you can get to a Paris-like outcome is by slamming hard on emissions,” he says, “reducing them as fast as humanly possible as well as investing now in these technologies that’ll give you these gigatonne gains in 20 or 30 years time.”
”The question for most of these technologies is – we don’t know if they work. But we need them to work.”
Flannery says solar-radiation management approaches should be treated with great caution, as they mask the problem: they will reduce the temperature, but not affect rising CO2 levels, leaving the oceans ever more acidic. That could see a catastrophic loss of reefs and oceanic life, devastating the aquatic food chain.
Ironically, one of the reasons the atmosphere isn’t already at a 2C warming mark, says Professor Karoly, is due to the aerosols already in the atmosphere – an unintentional form of solar radiation management.
He says the current best estimate of stabilising the temperature at that level, with a 50 per cent likelihood, is for a carbon equivalent reading of 420-480ppm. The current figure is 481ppm, and rising at 3ppm per year.
Solar radiation management – deliberate and large scale – might buy time in an emergency, says Flannery. “There’s a broad highway to hell that’s easy to go down and it’s really cheap, relatively. It’s instantly effective, nations can do it unilaterally and it gives you a lower temperature.
“But there’s a narrow, crooked, winding path to heaven which is the carbon reduction stuff. It’s at a very early stage, but that actually does solve the problem.”

Once we capture carbon, it can actually be used productively. American researchers have produced carbon nanofibres from atmospheric carbon dioxide – initially only 10g per hour, but they are convinced it could scale.
There could be vast baths of molten chemicals across large swathes of the Sahara Desert, powered by solar radiation, forming layers of a valuable building material on submerged electrodes.
A research project at a California university has gone further, manufacturing a building material dubbed CO2NCRETE from captured carbon dioxide. A pilot plant at Australia’s University of Newcastle is investigating whether a similar process, combining excess CO2 from an Orica plant with minerals to form building materials, has commercial potential.
Flannery is interested in desktop studies on carbon-sucking seaweed and algae, as well as research reporting that carbon dioxide can be made to fall as snow over the Antarctic.

Picture this: the temperature plummeting well below freezing until a blizzard of dry ice cascades onto the barren plains below, each cuboctahedral flake representing a miniscule improvement in carbon levels, to be stored safely – somehow – from warming into a gas and re-entering the air.
“We’re at very, very early days,” Flannery warns. “Various approaches have different favourable aspects to them, but I don’t think any of them are anything like a silver bullet.”
Flannery’s championing of unorthodox technologies – even as avenues for research – isn’t shared by many high-profile climate change campaigners. David Karoly calls Flannery’s interest “surprising”. He deems ideas such as dry ice snowfall in Antarctica as “rather technofix solutions”.
“How do you get sufficient CO2 out of the atmosphere and store it?” asks Professor Karoly. “It’s probably the most inhospitable environment in the world and he’s talking about – if you work out what this equates to, it’s a mountain higher than Everest, the size of a soccer field every year.”
The Paris target of a 1.5C rise is “virtually impossible” without new technologies, he says, which “have not been proved either commercially viable or without major harm”.
“My concern is, the cure might be substantially worse than the disease.”
Clive Hamilton, professor of public ethics at Charles Sturt University, who wrote about geoengineering in his 2013 book Earthmasters, is more blunt.
“The schemes [Flannery] proposes are real pie-in-the-sky stuff, way out there,” he says. “He seems to have been sucked in by a kind of strange techno-promise that’ll get us out of this.”

Australian geoengineering research lags far behind the world leaders in the US, UK and Germany. It’s limited to a handful of scientists in Sydney and Hobart, and our major achievement is helping to halt commercial oceanic geoengineering.
The federal government, via its Direct Action policy, focuses on carbon sequestration without the crazy technofix label. Instead it backs land-use practices such as planting new forests, and prioritises soil enhancement, mangrove protection and rainforest recovery.
“There was an enormous groundswell of support for these activities in Paris,” a spokesperson for the Department of the Environment says. “Other actions [in the geoengineering field] would have an enormously high safety bar to cross and are a long way from proof.”
Meanwhile, CSIRO looks set to embark on an expansion of its geoengineering research program, both at land and sea. In a recent memo to staff announcing 350 job cuts at the organisation, CSIRO head Larry Marshall nominated “climate interventions (geo-engineering)” as one area in which it would seek a “step change” in knowledge.
“CSIRO is currently working through the detail of our future climate adaptation and mitigation research, and will include research relevant aspects of onshore and offshore geo-engineering. The scale and scope of this research is still to be determined,” a CSIRO spokesperson told SBS.

 
Jim Falk categorises geoengineering proposals along various lines, including how big a project needs to be for credible deployment, how big an impact it would have, whether it is reversible, what governance is required, how much it would cost, and the risks involved.
“Then you can say different proposals have different footprints,” Falk says, “and depending on the footprint you can suggest what sort of barriers you would want for their regulations before you would allow an experiment to take place.”
Unlike attempts to reduce global carbon emissions – where everyone must do their part for action to be effective – what scares scientists about solar radiation management is the relative ease of one person launching a planet-wide experiment.
Spraying sulphate particles into the atmosphere from aircraft or balloons is known to reduce temperatures. It mimics what happens when volcanic ash blankets the atmosphere.
There would be spectacular sunsets as solar rays interact with the particles, with brilliant red eddies splashing the evening sky, similar to those in Edvard Munch’s famous painting The Scream.
And it has been costed at just $US10 billion a year.
One test in August 2008 was conducted on land 500km southeast of Moscow by Yuri Izrael, Russian President Vladimir Putin’s science advisor. He and his team rigged aerosol sprays on a helicopter and car chassis, measuring how solar radiation was retarded at heights up to 200 metres.
“China might decide to pump a load of sulphur into the atmosphere and not tell anyone about it,” says Rosemary Rayfuse, a Law professor at UNSW and a global authority on regulating geoengineering. “Or Australia could do it. Anybody could. That’s the other problem – it’s so easy to do.”
Billionaires Bill Gates and Richard Branson could step forward, says Anita Talberg, a PhD student in the governance of climate engineering at the University of Melbourne. Both support geoengineering and have funded research.
“They could just decide suddenly, ‘I could do enough benefit for the poor and vulnerable in the world, I could just do it and save them from the climate crisis.’”
Such a move could be catastrophic, most immediately due to the risk of drought in the tropics, devastating the food security of billions of people. Those colourful sunsets are projected to see lower rainfall.
The sky will bleach white during the day, while ozone depletes in the tropics – where most of the world’s population live. As the temperature falls, levels of UV radiation will rise, leading to an upsurge in skin cancers.

Professor Andy Pitman, of the Climate Change Research Centre in Sydney, is a member of the World Climate Research Program.
The only role he sees for sulphate injection is alongside steep cuts in carbon emissions. “If people are talking about it as a substitute for that, the technical term you’d use is ‘cloud cuckoo land’.”
But he hopes it’s never necessary.
“God, I hope not. We have a well-studied problem called global warming – we’re not sure of every detail – that would breach every ethics experiment on the planet if you proposed it as an experiment.
“All those problems relate to solar radiation management and I’d suggest any country that tried it at any significant level would find itself in every court in the world.”
There are smaller-scale approaches, he says, without the “ethical problems”. One is painting roofs white to reflect sun, a backyard approach anyone can try, and which would help cool interiors during hot summer days.
Another is genetically modified crops with a higher reflectivity, with variations as simple as leaves that are hairier or have a waxier coating.
Harvard University’s Professor David Keith is leading more research into solar radiation management, arguing in a 2015 paper that the technique could be used in a “temporary, moderate and responsive scenario”.
“Even if we make deep emissions cuts, it might be that the benefits of solar geoengineering outweigh the risks,” he tells SBS. “Or maybe not. To know, we have to decide to learn more.”
 

The belief in a technical solution – that because we have to find something, we will – has psychological roots in an effect known as ‘optimism bias’, says Melbourne psychologist Dr Susie Burke, who has expertise on issues relating to the environment, climate change and natural disasters.
“It’s intrinsic to humans to be optimistically biased,” she says, “and it’s great because it gets us out of bed in the morning and gives us a healthy motivation. But with respect to climate change, it means we end up minimising our personal risk and even risks that pertain to us – and believing the worst problems will happen to other people, somewhere else or into the future.”
She adds, “With the general population who are struggling to make significant changes to their lifestyle, deep down there is a belief that someone, somewhere will come up with something to solve the problem.”
Even talking about geoengineering carries the risk of “moral hazard”, that a solution to rocketing carbon emissions means they can continue unabated. That scenario troubles many.
“There’s a moral hazard in not discussing these things as well,” says Tim Flannery, “because we know we’re going to need them.”
The worst-case scenario – international agreements fail to stop emissions from rising – would force the use of extreme measures. Clive Hamilton thinks sulphate injection is the most likely use of geoengineering, though not yet.
“If we have a series of years where there are catastrophic droughts, heatwaves and hurricanes which cause massive impacts in several countries – also tipping points, so permafrost is now irreversibly melting – what kind of political and geostrategic environment are we going to be facing?” he asks.
“I think in that kind of scenario – which is not just possible but fairly likely – certain scientists promising they can rapidly reduce the earth’s temperature within a year or two are going to start looking increasingly attractive to some nations.”
Andy Pitman says that could lead to war: “You can imagine a situation – and it’s not too far-fetched – where country X starts a major campaign around sulphur injections into the atmosphere, country Y’s rainfall dramatically declines and is going into serious long-term famine, and that instigated a military response.”
And if carbon emissions continued to rise, the sulphate injection would have to be continuous. Otherwise, the particles would drop out of the atmosphere, leading to a sudden, highly disruptive jump in temperature.
If a war, say, or a pandemic was responsible for the break in sulphate injection, the compounding effects could be existential. 

Talking of human extinction in such a scenario is not too far-fetched.

 
The possibilities are less apocalyptic for some form of carbon capture and storage. 

Clive Hamilton identifies land being used by the likes of BECCS – bio-energy carbon capture and storage – to capture carbon as one of the main changes in geoengineering in the last few years.
Plants and trees would be grown for fuel, and the resulting carbon emissions from power generation would be stored away. There’s an example of this in Illinois at an ethanol production plant.
But there are questions over BECCS, not least that “no such economic process [is] available at this point and there may never be”, says Jim Falk.
The sheer amount of land needed is staggering, too. 

In a February 2016 paper in Nature,environmental scientist Philip Williamson estimated that one-third of the world’s arable land (430-580 million hectares of crops) would need planting for BECCS use to limit the temperature rise to 2C by 2100.

This would accelerate deforestation and, given “not unrealistic” assumptions, see carbon emissions actually increase.
Oliver Munnion, of the UK-based BioFuelwatch website, argues that BECCS is more dangerous than solar radiation management.

 “It’s the most outrageous,” he says. “It’s also the favoured approach amongst policy-makers, scientists and industry.
“The idea that we’d harm proven carbon sinks – forests and soils – to create an unproven and untested carbon sink underground is the antithesis of what climate policy should be geared towards.”
The problem facing geoengineering advocates is that most dangerous schemes are possible, but need to be used as a last resort, while the most promising schemes aren’t possible at scale. 

Even if they were, the numbers quickly turn ugly.
In the Nature article, Philip Williamson estimated that growing seaweed as a carbon pool would use nine per cent of the world’s oceans, with unknown environmental impacts.
Utilising the simple solar-radiation management tool of laying a reflective rock on the ground to reduce carbon levels by 12 per cent would need 1-5 kg/sqm of rock to be applied to 15-45 per cent of the earth’s surface, at a total cost of US$60-600 trillion.

That means an area of land at least the size of the old Soviet Union would have to be set aside and the global economy bankrupted.
The further you look, the more improbable geoengineering concepts become. A presentation to the 2016 American Meteorological Conference on Atmospheric Science called for lasers in the sky to microwave and neutralise methane clouds (another greenhouse gas).
UNSW Law professor Rosemary Rayfuse recalls one UK project looking at increasing the reflectivity of the oceans by making white foam, which had to persist for at least three months: “They were proposing to cover the oceans in meringue, which I thought was rather funny!”
David Karoly calls the idea of hanging mirrors in space to reflect sunlight “just stupid”, calculating the need for one million square kilometres of alfoil. Flannery agrees: “Anything that masks the problem, and lets people think they’ve solved it, is a danger.”
Cutting carbon emissions drastically, and now, would start to solve the problem. But that isn’t happening. Campaigners such as Tim Flannery are crossing their fingers that carbon-scrubbing technology we need to take us on “the narrow winding path to heaven” is developed in time.
If neither happens, we’ll be heading down the “broad highway to hell” of having to rely on solar radiation management, where the devil we don’t know is better than a climate gone rogue.
The effects of pumping simulated volcanic fallout into the atmosphere could dwarf the biggest eruptions in history. Start preparing for vivid red sunsets – and an uncertain future

Deep Oceans Face Starvation by End of Century #climatechange #science #auspol 

Deep Oceans Face Starvation by End of Century

A habitat that covers half the planet.

The deep ocean floor, Earth’s largest habitat, will be starved of food by the end of this century, scientists have warned. 
New research published in the open-access journal Elementa today shows that food supply to some areas of the earth’s deep oceans will decline by up to half by 2100.
Andrew Sweetman of the Lyell Centre for Earth and Marine Science and Technology at Heriot-Watt University in Edinburgh, Lisa Levin, a biological oceanographer at Scripps Institution of Oceanography at the University of California San Diego, and colleagues from 20 of the world’s leading oceanographic research centers used earth system models and projected climate change scenarios to quantify impending changes to deep oceans in the review released Feb. 23.
The team looked at a number of sea and ocean beds, from the Arctic to Antarctic oceans, focusing on bathyal (200-3,000 meter or 650-9,800-foot) and abyssal (3,000-6,000 meter or 9,800-19,700-foot) depths, the areas defined in the paper as deep ocean. As well as measuring how the deep oceans’ food sources will change, the team examined the impact that predicted seabed temperature increases, oxygen level declines, and increasingly acidic seawater will have, under the sea and across the planet.
“The rate of change underway in our oceans is faster than at any point we know of in geological history,” said Sweetman. “Deep seafloor ecosystems provide services that are vitally important to the entire ocean and biosphere; we should all be concerned at what’s happening on our ocean floors. The organic matter cycling that occurs in the deep sea helps to buffer the ocean against pH changes and the effects of ocean acidification.” 
The changes that are projected in the deep ocean, which accounts for more than 95 percent of the volume of the Earth’s oceans, are likely to significantly alter the health and sustainable functioning of the planet over the next couple of centuries.
“Because many deep-sea environments are naturally very stable in terms of environmental conditions, even slight changes in temperature, oxygen, food supply, and pH are likely to significantly lower the resilience of deep-sea communities to the impact of human activity,” said Levin. “These many challenges call for intensified observations of and spatial planning for the deep ocean, coordinated at an international level.” 
Organic compounds produced through primary production – the creation of chemical energy by algae and other phytoplankton through photosynthesis – sink to the deep ocean and make up much of the food supply there. Most of the deep sea currently experiences a severe lack of food, but according to Sweetman and his research team, it is about to receive even less. That’s because the phytoplankton deep sea organisms rely upon are themselves facing a dwindling supply of nutrients in the surface oceans as warming makes waters more stratified.
Sweetman continued: “Abyssal ocean environments, which are over 3,000 meters deep, are some of the most food-deprived regions on the planet. These habitats currently rely on less carbon per square meter each year than is present in a single sugar cube. We’ve shown that large areas of the abyss will have this tiny amount of food halved by 2100. For a habitat that covers half the earth, the impacts of this will be enormous.”
The researchers also describe an imminent, significant temperature increase that will happen at the deepest parts of the ocean.
“Deep-sea ecosystems are not just going to experience a reduction in food, but will likely also experience an increase in ocean temperature of 1°C within 85 years,” said Andrew Thurber, co-author of the study and a professor at Oregon State University. “This is very worrying because increasing temperature will increase the metabolism of animals and microbes that live in the sediment, meaning they will require more food at a time when much less is available.”
The scientists also examined how certain human activity will continue to affect the deep ocean.
Sweetman said the deep sea is fast becoming a target area for increased exploitation of key resources and the dumping of pollutants. Pressure from fishing has led to many deep-sea fish species being severely exploited through trawling and long-lining, with some species having been fished to commercial extinction.
“There is also extensive interest in mineral mining at hydrothermal vent systems along mid ocean ridges, at seamounts and polymetallic nodule areas at abyssal depths, such as the Clarion Clipperton Zone of the Pacific Ocean,” he added. 
The review is based on a workshop led by Sweetman and funded by the Norwegian Research Council.
Summary of key findings
Over the next 84 years, the highest temperature changes are likely to occur at the abyssal seafloor in the North Atlantic, Southern and Arctic oceans (0.5-1oC). 

Bathyal depths are also likely to experience increasing temperatures of approximately 4 °C in the Pacific, Atlantic, and Arctic oceans.

Bathyal seafloor habitats in the North Pacific, North Atlantic, Arctic and Southern oceans could experience a reduction in bottom-water oxygenation by 0.03–0.05 milliliters per liter by the year 2100, which represents a reduction in water column O2 levels by 0.5–3.7 %.

Ecosystems within and on the fringes of oxygen minimum zones could be particularly affected by the O2 and warming changes predicted for bathyal environments.

Bathyal seafloor habitats in the North Atlantic and the Weddell Sea, Antarctica in other areas of the world´s oceans will also experience a decrease of 0.29 to 0.37 pH units by the year 2100, as a result of the entrainment of CO2-rich seawater to the seafloor at sites of bottom-water formation.

The areas likely to be impacted by significant declines in food supply lie in the North and South Pacific, North and South Atlantic, and North and South Indian oceans. The abyssal and bathyal regions of the Indian Ocean are predicted to experience declines in food supply by as much as 40 percent and 55 percent, respectively by 2100.

No one will be untouched’: Climate change will lead to war, famine and extreme weather, claims IPCC report
Report said we have seen impacts of global warming on every continent

Experts warned people are ill prepared to cope with the dramatic change

It predicted violent conflicts, food shortages and infrastructure damage 

Extreme weather will increase poverty and damage animal and sea life
By Ellie Zolfagharifard

No one will be untouched by climate change with storm surges, flooding and heatwaves among the key risks of global warming in the coming decades, claim scientists.
This was the warning made in the Intergovernmental Panel on Climate Change (IPCC) Working Group II report.
The report said that violent conflicts, food shortages and serious infrastructure damage were also predicted to become more widespread over the coming years.


The IPCC has predicted that few areas will be left untouched by the impacts of climate change, which they say will include increasing levels of extreme weather events such as heatwaves and snow storms
It argued that rising temperatures will exacerbate poverty and damage land and marine species.
It also claimed that the world is in ‘an era of man-made climate change’ and has already seen impacts of global warming on every continent and across the oceans.
And experts warned that in many cases, people are ill-prepared to cope with the risks of a changing climate.
The IPCC report is the first comprehensive analysis in seven years of the global consequences of climate change.

Open Letter to President Trump on Climate Change #auspol #science

Hingham couple pens open letter to President Trump on climate change
By John and Sally Davenport Hingham Journal

As we believe you must know in your heart of hearts, human-caused climate change is not a hoax.

 Virtually no one believes that climate change is not occurring. 

The globe is warming even faster than climate scientists have predicted, particularly at the poles where the ice is melting at an alarming rate. 


The overwhelming view of the scientific community world-wide is that global climate change is being caused by humans through the burning of fossil fuels and the release into the atmosphere of carbon dioxide and other greenhouse gasses. (The warming effect of atmospheric carbon dioxide has been known since the mid-19th century.) 

Most climate models show that, if carbon dioxide and other greenhouse gas emissions continue at the current rate, global temperatures will rise to potentially catastrophic levels by 2100.
These scientists from all over the world do not have any political axe to grind or financial stake in whether climate change is or is not caused by humans. 

They have no interest in participating in the perpetration of a hoax. 

Even climate scientists employed by oil and gas giant Exxon Mobil were unanimous in their advice to their employer, beginning in the 1970s, that the burning of its products was causing global warming.

Studies have shown that the widespread skepticism among conservatives about human-caused climate change stems from their dislike of governmental regulation and international commitments, not from doubt about the accuracy of the climate change science. Otherwise, why would Republicans generally reject the science while Democrats do not? (Republicans and Democrats alike agree about the validity of other, politically neutral, science, such as their own doctors’ science-based medical advice).
The science must be separated from the politics.

 The political debate must not be about the validity of the science of human-caused global warming; let the climate scientists debate that.

 Rather, the political debate must be about what to do about it, ranging from nothing, to promoting renewable energy and stimulating growth of the green economy, to limiting carbon dioxide emissions, to implementing a cap and trade regime. Then there can be a healthy policy debate about the impact of such measures on the economy and their effectiveness in avoiding catastrophic climate change.

Pulling out of the Paris accord and revoking the Clean Power Plan and other measures put in place by prior administrations to curb greenhouse gas emissions and global climate change in the hope that the climate scientists are wrong or overly pessimistic is the equivalent of playing Russian roulette, with possible consequences less instantaneous but infinitely more catastrophic. Arguing about the degree of certainty in the climate change projections is like arguing about whether to play the game with five bullets in the six-shooter or just two or three.
Abandoning governmental actions to curb global warming will be a terrible legacy for you and your administration to leave to our children and grandchildren, to the country, and to the world.

The Slow Confiscation of Everything #auspol 

The Slow Confiscation of Everything

By Laurie Penny 


A protest against EPA head Scott Pruitt. / Lorie Shaull
These days, the words of the prophets are written in whimsical chalk on the hoardings of hipster latte-mongers: “The end is nigh. Coffee helps.”

 In the days running up to the inauguration of Donald Trump, I saw this sort of message everywhere, and as panic-signals go, it’s oddly palliative. 

The idea that the Western world might soon be a smoking crater or a stinking swamp does, in fact, make me a little more relaxed about the prospect of spending five dollars on a hot drink.  
Fuck it. 

The planet, as we keep telling each other, is on fire. 

Might as well have a nice latte while we wait for the flames to slobber up our ankles. 

When you consider that some desperate barista boiled the entire philosophy of post-Fordist public relations down to its acrid essence, it would be ungrateful not to. 

What have you got to lose? 

Five dollars and your pride, in the short term, but what will those be worth next year? 

Next week? 

Have you looked at the Dow Jones lately? 

Have you turned on the news? 

On second thoughts, best not—just drink your coffee and calm down. 

Look, they’ve drawn a little mushroom cloud in the milk foam. 

It’s quite beautiful, when you think about it. 
The topic of apocalypse comes up a lot these days. 

It’s slipped into conversation as compulsively as you might mention any other potentially distressing disruption to your life plans, such as a family member’s illness, or a tax audit. 

And yet the substance of the conversation has shifted in recent weeks and months from an atmosphere of chronic to acute crisis. 

The end seems to be slightly more nigh than it was last year; we talk about the Trumpocalypse with less and less irony as the Bulletin of the Atomic Scientists moves the Doomsday clock half a minute closer to midnight. 
Of all the despicable things the runaway ghost train of the Trump administration has done in its first ferocious weeks, the attempt to utterly destroy every instrument of environmental protection is perhaps the most permanent.

 The appointment of fossil fuel tycoons and fanatical climate change deniers to key positions in energy and foreign policy, the immediate reinstitution of the Dakota Access and Keystone pipelines, the promise to pull out of the Paris Climate Pact—all moves crafted to please the oil magnates who helped put him in power—these are changes that will hasten the tick of the time bomb under civilization as we know it. 

Racist laws can eventually be overthrown, and even a cultural backslide toward bigotry and nationalism can be slowly, painfully reversed. 

We don’t get a do-over on climate change. 

The vested interests agitating to strip the planet for parts know that, too—and they plan to profit from this particular apocalypse as hard as they can.
They’re not the only ones eagerly anticipating the end times. 

Apocalyptic thinking has a long and febrile history in Western thought, and it is usually associated with moments of profound cultural change, when people found it all but impossible to envision a future they might live inside. 

The notion of armageddon as something to look forward to crops up time and again at moments of profound social unrest. 

Today, that includes legions of lonely alt-righters celebrating the advent of a new post-democratic, post-civilizational age where men will be real men again, and women will be really grateful. 


This “dark enlightenment” rumbles alongside a massive revival in millenarian end-times fanaticism among the Evangelical Christians who overwhelmingly voted for a man some of them believe is the literal antichrist who will hasten the final return of Jesus and his arse-kicking angels to sweep the righteous to their reward. 

There are many millions of people, especially in the United States, who seem to want an apocalypse—a word whose literal meaning is a great “unveiling,” a moment of calamity in which the murkiest and basest of human terrors will be mercifully swept aside. 

That gentle armageddon, however, looks unlikely to be delivered. 

Frightened, angry human beings have always fantasized about the end of the world—and institutions of power have always profited from that fantasy. 

In fact, as David Graeber notes in Debt: The First 5,000 Years, the ideal psychological culture for the current form of calamity capitalism is an apprehension of coming collapse mated bluntly with the possibility of individual escape. 

An economy driven by debt and fueled by looting and burning the resources that have sustained the species for generations would feel far more monstrous if it weren’t for the lingering suspicion that it might all be in flames tomorrow anyway.

 The world is on fire. 

Might as well build that pipeline. 

Might as well have that coffee.

But what world is on fire? 

The late comedian George Carlin had it right when he reminded us that

 “The planet is fine. The people are fucked.” 

The Earth is resilient, and will stagger on in some form until it is swallowed by the sun some four billion years from now—the world that we envision ending is Western civilization as we have come to understand it, a mere eyeblink in the long species churn of planetary history. 

Apocalyptic thinking has been a consistent refrain as the human species struggles to evolve beyond its worst impulses, but the precise form of the anticipated collapse always changes. 

Those changes are important. 

The catastrophes we are anticipating today are not the catastrophes of thirty years ago, and that distinction matters a great deal.
Climate change is this generation’s calamity, and it is similar to the nuclear threat that nurtured the baby boomers in that it promises a different sort of death from the petty disasters of war, famine, and pestilence—it promises near-total species collapse. 

The past swept away along with the future. 

The deletion of collective memory. 

This is an existential threat more profound than anything humanity has had to reckon with before except in the throes of ecstatic religious millenarianism.

 Rapture, in the Abrahamic understanding, traditionally meant immortality for the species.

 We are the first to really have to wrestle with ultimate species death, extinction in memory as well as being.

 Of course we are afraid. 

We were afraid of the Bomb. 

We’re afraid now, even though many people’s understanding of climate change hasn’t moved past the denial stage.

 It is there, however, that the similarities between the two types of apocalypse end.
Climate change is a different prospect of calamity—not just elementally but morally different from nuclear exchange in a manner which has not been properly dealt with. 

The first difference is that it’s definitely happening. 

The second is that it’s not happening to everyone. 
There will be no definite moment can say that yes, today we are fucked, and yesterday we were unfucked.

For anyone who grew up in the Cold War, the apocalypse was a simple yes-no question: either it was coming, or it wasn’t. 

Many people I know who grew up before the end of the nuclear arms race describe this as oddly freeing: there was the sense that since the future might explode at any point, it was not worth the effort of planning. 

Climate change is species collapse by a thousand cuts. 

There will be no definite moment we can say that yes, today we are fucked, and yesterday we were unfucked. 

Instead the fuckery increases incrementally year on year, until this is the way the world ends: not with a bang, not with a bonfire, but with the slow and savage confiscation of every little thing that made you human, starting with hope.


“In the U.S. we have a very strong sense of apocalypse that comes from puritanism, and it fed nicely into fears about the Bomb,” says Annalee Newitz, author of Scatter, Adapt and Remember: How Humans Will Survive A Mass Extinction.

 “Both kinds of apocalypse are instantaneous and there’s not much you can do about them. 

But climate change is slow and strange, sometimes imperceptible in a human lifetime. 

There are no pyrotechnics. 

Plus, we actually have a chance to intervene and prevent the worst effects of it. 

I think that’s a tough sell for people who grew up with a Bomb paradigm of apocalypse, where there’s either fiery atomic death or you’re fine. 

It’s hard to explain to people that there are probabilities and gradations of apocalypse when it comes to the environment, and there are hundreds of ways to mitigate it, from curbing emissions to preserving natural habitats and changing our agricultural practices. 

In a weird way, I think people are just now getting used to the slow apocalypse, and still don’t know how to deal with it.”
This was the unegalitarian apocalypse millennials inherited. 

If we are to define generations by their political impressions, one thing that everyone who grew up with no memory of the Cold War shares is a specific set of superstitions. 

 One of them was the consensus that neoliberalism had produced the “End of History.” 

For those of us who had not read Francis Fukuyama by the age of five, this came across as a general sense that there was no better society to hope for, no way of living on the horizon that would improve on the one we had been raised to—the nineties and the early aughts were as good as it was going to get.

 From here on in, unless we recycled and remembered to turn off the taps like the singing Saturday afternoon TV puppets urged us to, it would be slow collapse. 

Our parents, relieved of the immediate threat of atomic incineration, seemed oddly calm about that prospect.
Not half as calm, however, as our elected and unelected leaders.

 Because that’s the inconvenient truth, the other inconvenience about the world ending this way: it’s not ending for everyone.
This month, in a fascinating article for The New Yorker, Evan Osnos interviewed several multi-millionaires who are stockpiling weapons and building private bunkers in anticipation of what preppers glibly call “SHTF”—the moment when “Shit Hits The Fan.” 

Osnos observes that the reaction of Silicon Valley Svengalis, for example, is in stark contrast to previous generations of the super-rich, who saw it as a moral duty to give back to their community in order to stave off ignorance, want and social decline. 

Family names like Carnegie and Rockefeller are still associated with philanthropy in the arts and sciences. 

These people weren’t just giving out of the goodness of their hearts, but out of the sense that they too were stakeholders in the immediate future.
Cold War leaders came to the same conclusions in spite of themselves.

 The thing about Mutually Assured Destruction is that it is, well, mutual—like aid, or understanding, or masturbation.

 The idea is that the world explodes, or doesn’t, for everyone. 

How would the Cuban Missile Crisis have gone down, though, if the negotiating parties had known, with reasonable certainty, that they and their families would be out of reach of the fallout? 
How would the Cuban Missile Crisis have gone down if the negotiating parties had known that they and their families would be out of reach of the fallout?

Today’s apocalypse will be unevenly distributed.

 It’s not the righteous who will be saved, but the rich—at least for a while.

 The irony is that the tradition of apocalyptic thinking—religious, revolutionary or both—has often involved the fantasy of the destruction of class and caste. 

For many millenarian thinkers—including the puritans in whose pinched shoes the United States is still sneaking about—the rapture to come would be a moment of revelation, where all human sin would be swept away. 

Money would no longer matter. 

Poor and privileged alike would be judged on the riches of their souls. 

That fantasy is extrapolated in almost every modern disaster movie—the intrepid survivors are permitted to negotiate a new-made world in which all that matters is their grit, their courage, and their moral fiber. 
A great many modern political currents, especially the new right and the alt-right, are swept along by the fantasy of a great civilizational collapse which will wash away whichever injustice most bothers you, whether that be unfettered corporate influence, women getting above themselves, or both—any and every humiliation heaped on the otherwise empty tables of men who had expected more from their lives, economic humiliations that are served up and spat back out as racism, sexism, and bigotry. 

For these men, the end of the world sounds like a pretty good deal. 

More and more, it is only by imagining the end of the world that we can imagine the end of capitalism in its current form. This remains true even when it is patently obvious that civilizational collapse might only be survivable by the elite.
When it was announced that the Doomsday Clock had moved closer to midnight, I panicked for an entire day before realizing that, like a great many people, I didn’t know what the Doomsday Clock actually was.

 In case you were wondering, it’s not actually a real clock. 

It’s a visual representation of certain scientists’ estimation of how close human society is to catastrophe, published on the front cover of the Bulletin of the Atomic Scientists since 1947—a genius exercise in metonymy and public relations conceived in an age when the problem was not that people were panicking about the end of the world, but that they weren’t panicking enough. 

There is no sympathetic magic at play: if a drunk sub-editor got into the layout program and moved the portentous second hand all the way to Zero Hour on a whim, no rockets would fire of their own accord. 

This apocalypse is still within our power to prevent—and that starts with abandoning the apocalyptic mindset.
It is hard to outline the contours of a future you have never been allowed to imagine—one that is both different from today but accessible from it, too. 

The best we have been permitted to hope for is that the status quo be scraped to the edges of the present for as long as it lasts—a vote to run the knife around the empty jar of neoliberal aspiration and hope there’s enough to cover our asses.

 If people cannot imagine a future for themselves, all they can measure is what they’ve lost. 

Those who believe in the future are left, as they always were, with the responsibility of creating it, and that begins with an act of faith—not just that the future will be survivable, but that it might, somehow, maybe, be an exciting place to live. 
“Every ruthless criticism of current politics should be tied in some way to an example of how we could do things better,” said Newitz. “I realize that’s a tall order, especially when positive visions often feel like wishful thinking rather than direct action. Nevertheless we need to know what we are fighting for to retain our sense of hope. We need maps of where we are going, not just fire to burn it all down.”

Irreversible Threshold of #ClimateChange 

IN LATE 2015, a chilling report by scientists for
the International Cryosphere Climate Initiative
on 

“Thresholds and closing windows: Risks of irreversible cryosphere climate change”

Warned that the Paris commitments will not prevent the Earth 

“crossing into the zone of irreversible thresholds”


In polar and mountain glacier regions, and that crossing these boundaries may 

“result in processes that cannot be halted unless temperatures return to levels below pre-industrial” 

The report says it is not well understood outside the scientific community that cryosphere dynamics are slow to manifest but once triggered “inevitably forces the Earth’s climate system into a new state, one that most scientists believe has not existed for 35–50 million years” 


Ian Howat, associate professor of earth sciences at Ohio State University, says: 

“It’s generally accepted that it’s no longer a question of whether the West Antarctic Ice Sheet will melt, it’s a question of when. 

This kind of rifting (cracking) behaviour provides another mechanism for rapid retreat of these glaciers, adding to the probability that we may see significant collapse of West Antarctica in our lifetimes.”


The scientists I have communicated with take the view that Rignot, Mouginot et al. is a credible paper and, together with the evidence published since, it would be prudent to accept that WAIS has very likely passed its tipping point for mass deglaciation, with big consequences for global sea level rise (SLR). 

DeConto and Pollard project more than a metre of SLR from Antarctica this century. 

This tallies with the Hanse, Sato et al scenario, which is also consistent with the findings of Phipps, Fogwill and Turney.

The reality of multi-metre SLRs is not if, but how soon. 

“The natural state of the Earth with present CO2 levels is one with sea levels about 70 feet (21 metres) higher than now” 

says Prof. Kenneth G. Miller. 

Other research scientists agree it is likely to be more than 20 metres over the longer term.

So how much could we expect sea levels to rise this century?

We’re at War to save the planet! #auspol #climatechange #science 

By Paul Mason

It hits you in the face and clings to you. 

It makes tall buildings whine as their air conditioning plants struggle to cope.

 It makes the streets deserted and the ice-cold salons of corner pubs get crowded with people who don’t like beer. 

It is the Aussie heatwave: and it is no joke.

Temperatures in the western suburbs of Sydney, far from the upmarket beachside glamour, reached 47C (117F) last week, topping the 44C I experienced there the week before.

 For reference, if it reached 47C in the middle of the Sahara desert, that would be an unusually hot day.
For Sydney, 2017 was the hottest January on record. 

This after 2016 was declared the world’s hottest year on record. 

Climate change, even in some developed societies, is becoming climate disruption – and according to a UN report, one of the biggest disruptions may only now be getting under way.

El Niño, a temperature change in the Pacific ocean that happens cyclically, may have begun interacting with the long-term process of global warming, with catastrophic results.
Let’s start by admitting the science is not conclusive. 

El Niño disrupts the normal pattern by which warm water flows westwards across the Pacific, pulling the wind in the same direction; it creates storms off South America and droughts – together with extreme temperatures – in places such as Australia. 

It is an irregular cycle, lasting between two and seven years, and therefore can only be theorised using models.
Some of these models predict that, because of climate change, El Niño will happen with increased frequency – possibly double. 

Others predict the effects will become more devastating, due to the way the sub-systems within El Niño react with each other as the air and sea warm.
What cannot be disputed is that the most recent El Niño in 2015/16 contributed to the extreme weather patterns of the past 18 months, hiking global temperatures that were already setting records.

 (Although, such is the level of rising, both 2015 and 2016 would have still been the hottest ever without El Niño.) 

Sixty million people were “severely affected” according to the UN, while 23 countries – some of which no longer aid recipients – had to call for urgent humanitarian aid. 


The catastrophe prompted the head of the World Meteorological Association to warn: 

“This naturally occurring El Niño event and human-induced climate change may interact and modify each other in ways that we have never before experienced.”
The warning was enough to prompt the UN to issue a global action plan, with early warning systems, beefed-up aid networks and disaster relief preparation, and calls for developing countries to “climate proof” their economic plans.
Compare all this – the science, the modelling, the economic foresight and the attempt to design multilateral blueprint – with the actions of the jackass who runs Australia’s finance ministry.

Scott Morrison barged into the parliament chamber to wave a lump of coal at the Labor and Green opposition benches, taunting them: 

“Don’t be afraid, don’t be scared. 

It’s coal. 

It was dug up by men and women who work in the electorate of those who sit opposite.” 

Coal, argues the Australian conservative government, has given the economy “competitive energy advantage for more than 100 years”. 

Labor and the Greens had called, after the Paris climate accord, for an orderly shutdown of the coal-fired power stations that produce 60% of the country’s energy.
The Aussie culture war over coal is being fuelled by the resurgence of the white-supremacist One Nation party, led by Pauline Hanson, which is pressuring mainstream conservatives to drop commitments to the Paris accord and, instead, launch a “royal commission into the corruption of climate science”, which its members believe is a money-making scam.
All over the world, know-nothing xenophobes are claiming – without evidence – that climate science is rigged. 

Their goal is to defend coal-burning energy, promote fracking, suppress the development of renewable energies and shatter the multilateral Paris agreement of 2015.


Opposition to climate science has become not just the badge of honour for far-right politicians like Ukip’s Paul Nuttall.

 It has become the central tenet of their appeal to unreason.
People facing increased fuel bills, new taxes on methane-producing cattle farms, dimmer light bulbs and the arrival of wind and wave technologies in traditional landscapes will naturally ask: is this really needed? 

Their inner idiot wishes it were not. 

For most of us, the inner rationalist is strong enough to counteract that wish.

What distinguishes the core of the rightwing populist electorate is its gullibility to idiocy-promoting rhetoric against climate science. 

They want to be harangued by a leader who tells them their racism is rational, in the same way they want leaders who tell them the science behind climate change is bunk.


Well, in Australia, people are quickly finding out where such rhetoric gets you: more devastating bushfires; a longer fire season; more extreme hot days; longer droughts. And an energy grid so overloaded with demands from air conditioning systems that it is struggling to cope.
And, iIf the pessimists among climate scientists are right, and the general rise in temperature has begun to destabilise and accentuate the El Niño effects, this is just the start.
The world is reeling from the election victory of Donald Trump, who has called climate science a hoax.

 Dutch voters look set to reward Geert Wilders, whose one-page election programme promises “no more money for development, windmills, art, innovation or broadcasting”, with first place in the election. 

In France, 27% of voters are currently backing the Front National, a party determined to take the country out of the Paris accord, which it sees as “a communist project”.
The struggle against the nationalist right must, in all countries, combine careful listening to the social and cultural grievances of those on its periphery with relentless stigmatisation of the idiocy, selfishness and racism of the leaders and political activists at its core.
It’s time to overcome queasiness and restraint. 

We, the liberal and progressive people of the world, are at war with the far right to save the earth. 
The extreme temperatures and climate-related disasters of the past 24 months mean this is not some abstract struggle about science or values: it’s about the immediate fate of 60 million people still recovering from a disaster.

European leaders warn of War #climatechange #auspol 

Among the 21st-century threats posed by climate change — rising seas, melting permafrost and superstorms — European leaders are warning of a last-century risk they know all too well: War.
Focusing too narrowly on the environmental consequences of global warming underestimates the military threats, top European and United Nations officials said at a global security conference in Munich this weekend. 

Their warnings follow the conclusions of defense and intelligence agencies that climate change could trigger resources and border conflicts.

“Climate change is a threat multiplier that leads to social upheaval and possibly even armed conflict,” the UN’s top climate official, Patricia Espinosa Cantellano, said at the conference, which was attended by the U.S. secretaries of defense and homeland security, James Mattis and John Kelly.

Even as European Union countries struggle to assimilate millions of African and Middle Eastern migrants and refugees, security officials are bracing for more of the same in the future. 

Secretary General Antonio Guterra named climate change and population growth as the two most serious “megatrends” threatening international peace and stability.
Hotter Than Ever
“Ground zero” for armed conflict over the climate will be the Arctic, where record-high temperatures are melting ice and revealing natural resources that some countries might be willing to fight for, Finland’s President Sauli Niinisto said on a panel.

“We have already seen flag planting and already some quarrels on the borderlines,” Niinisto said, pointing to new Russian military bases on its Arctic border. “Tensions will rise.”
The Arctic climate paradox — where countries could fight for rights to extract the very fossil fuels that would cause even more global warming — underscores energy’s role as a cause and potential moderator of climate change, according to Niinisto. 
For Russia, the world’s biggest energy supplier, European nations switching to renewables represents an economic threat. 

At the same time, European over-reliance on Russian energy exposes them to coercion, according to Kelly Gallagher-Sims, a former climate and energy adviser to President Barack Obama.


Peaceful Coexistence
“Climate change is already exacerbating existing stresses that contribute to instability and insecurity,” Gallagher-Sims told Bloomberg last week before leading a policy meeting on Arctic security at the Fletcher School at Tufts University near Boston. 

“The main relationship between renewable energy and trans-Atlantic security” is that clean power “permits Europe to rely less on Russian gas,” she said.
For their part, Russian leaders in Munich said they want peaceful coexistence with Europe and will abide by the Paris accord on climate change — even if it’s unlikely they’ll try convincing U.S. President Donald Trump to do the same.
It’s not clear when and if Trump will make good on his frequent campaign promises to pull the U.S. out of the Paris accord, a 2015 UN agreement to curtail greenhouse-gas emissions that was adopted by nearly 200 countries. 

Since he took office, the administration has rolled back U.S. rules to combat climate change and eased restrictions on fossil-fuel companies.
U.S. Democratic Senator Sheldon Whitehouse, a member of the committee on the environment and public works, told officials in the Bavarian capital they may have to fight to preserve the 2015 Paris agreement from global warming skeptics in the White House.
“The response of the international community will be significant,” Whitehouse said. 

While the probability of abandoning Paris may be small, they “decrease further if the response of the international community” to the U.S.

 “is not only, don’t you dare but, that there’ll be consequences in other areas” if you leave.

Climate Change One of Mankind’s Most Serious Threats. #Auspol 

Catastrophic Climate Change Makes List of Mankind’s Most Serious Threats
Extreme climate change is among the greatest threats facing mankind, says a new study released by the Global Challenges Foundation


Still politicians (Who receive huge donations from coal miners) push coal ignoring climate scientists.

The GCF works to raise awareness of Global Catastrophic Risks, defined as events that would end the lives of roughly 10 percent or more of the global population, or do comparable damage.

The list includes “significant ongoing risks” such as nuclear war and worldwide disease outbreaks but also highlights several scenarios that are “unlikely today but will become significantly more likely in the coming decades,”such as the continued rise of artificial intelligence. 

It’s there, among the emerging risks, that the study places the threat of catastrophic climate change.

Even if we succeed in limiting emissions, the study says, scientists expect significant climate change to occur, which could lead to a host of global challenges including environmental degradation, migration, and the possibility of resource conflict.

The study goes on to say that, in a worse case scenario, global warming could top 6 degrees Celsius, which would leave “large swathes of the planet dramatically less habitable.”
“The precise levels of climate change sufficient to trigger tipping points – thresholds for abrupt and irreversible change – remain uncertain,“ the study says, “but the risk associated with crossing multiple tipping points in the earth system or in interlinked human and natural systems increases with rising temperature.”

The main goal of the study is to raise awareness of these potential catastrophes and encourage greater global cooperation to keep them at bay.
(MORE: Climate Change Poses Urgent Health Risk, White House Says)
“Market and political distortions mean that these risks are likely to be systematically neglected by many actors,” the study says.
The study suggests there are three main ways to reduce the risks from climate change: adaptation to climate change, abatement of emissions, and geo-engineering. Research communities should increase their focus on understanding the pathways to and the likelihood of catastrophic climate change, and possible ways to respond, the study says.
