WHO report: Europe trails U.S. in cutting air pollution

trafficbw (1)

The New York Times reports: European countries, which rely heavily on diesel-fueled vehicles, remain far behind the United States in their efforts to reduce harmful air pollution, according to a report to be issued Thursday by the World Health Organization.

The report, which compiled air quality readings from 3,000 cities in 103 countries, found that more than 80 percent of people in those cities were exposed to pollution exceeding the limits set by W.H.O. guidelines, above which air quality is considered to be unhealthy. And in poorer countries, 98 percent of cities with more than 100,000 inhabitants were out of compliance with the health organization’s guidelines.

Lower levels of pollution were far more prevalent in North America and higher-income European countries than in most other places, especially countries like India, Pakistan and China.

But in Europe, a higher percentage of cities exceeded the limits set by the W.H.O. than in North America.

That disparity was greatest in wealthier countries; more than 60 percent of European cities failed to meet the guidelines, compared with less than 20 percent in North America. [Continue reading…]

Are oxygen-depleted oceans from California to Namibia a harbinger of the next mass extinction?

hypoxia-dead-zones

Moises Velasquez-Manoff writes: It was crabbers who first reported something amiss. In 2002, they began pulling in traps full of corpses. (Crabs should be alive when you catch them.) And they mentioned something else: Little octopuses had followed their crab lines to the surface, as if fleeing inhospitable conditions below.

Then heaps of dead crustaceans began washing ashore along a stretch of Oregon’s coast. When scientists sent a robotic submersible offshore, they discovered mile upon mile of dead crustaceans, the water brown and murky with detritus.

The killer was low oxygen, or hypoxia. Nearly all animals require oxygen to live, and, that year, dissolved oxygen had fallen so low off Oregon’s coast that whatever mobile creatures could had fled, while more-sessile life had simply suffocated.

Every year since, those hypoxic waters have appeared in late summer and early autumn. In 2006, they became anoxic, meaning they lost all their oxygen. “You didn’t see a single fish in a day,” says Jack Barth, a professor at Oregon State University, “just the piles of crab carcasses and worms that had come out of the bottom, sort of wafting in the current.” When scientists examined the roughly 50-year record of oxygen measurements from the region, they couldn’t find a single comparable event in the past. The hypoxia, it seemed, was unprecedented.

And then it spread.

In 2013, low-oxygen water showed up off the California coast just north of San Francisco. The following year, crabbers pulled in dead crabs in Half Moon Bay, just below San Francisco. Further south, the Monterey Bay Aquarium registered a decline in the oxygen content of the water it pumps in from the ocean.

“It seems like something has changed,” says John Largier, head of the Coastal Oceanography Group at the University of California-Davis. He tries to remain skeptical, but he suspects “large-scale global change.”

These suffocated patches of ocean aren’t just bad for fishermen and their catch; they represent a change in the ocean that has, at times in Earth’s past, heralded mass extinction. [Continue reading…]

One in five of world’s plant species at risk of extinction

lichen8

Phys.org reports: The first annual State of the World’s Plants report, which involved more than 80 scientists and took a year to produce, is a baseline assessment of current knowledge on the diversity of plants on earth, the global threats these plants currently face, as well as the policies in place and their effectiveness in dealing with threats.

“This is the first ever global assessment on the state of the world’s plants. We already have a ‘State of the World’s …birds, sea-turtles, forests, cities, mothers, fathers, children even antibiotics’ but not plants. I find this remarkable given the importance of plants to all of our lives- from food, medicines, clothing, building materials and biofuels, to climate regulation. This report therefore provides the first step in filling this critical knowledge gap.” said Professor Kathy Willis, Director of Science at the Royal Botanic Gardens, Kew at the report launch on Monday.

“But to have effect, the findings must serve to galvanise the international scientific, conservation, business and governmental communities to work together to fill the knowledge gaps we’ve highlighted and expand international collaboration, partnerships and frameworks for plant conservation and use,” she added.

The status of plants outlined in the report is based on the most up to date knowledge from around the world as of 2016 and is divided into three sections; describing the world’s plants, global threats to plants and policies and international trade. [Continue reading…]

Why we need to tackle the growing mountain of ‘digital waste’

By Chris Preist, University of Bristol

We are very aware of waste in our lives today, from the culture of recycling to the email signatures that urge us not to print them off. But as more and more aspects of life become reliant on digital technology, have we stopped to consider the new potential avenues of waste that are being generated? It’s not just about the energy and resources used by our devices – the services we run over the cloud can generate “digital waste” of their own.

Current approaches to reducing energy use focus on improving the hardware: better datacentre energy management, improved electronics that provide more processing power for less energy, and compression techniques that mean images, videos and other files use less bandwidth as they are transmitted across networks. Our research, rather than focusing on making individual system components more efficient, seeks to understand the impact of any particular digital service – one delivered via a website or through the internet – and re-designing the software involved to make better, more efficient use of the technology that supports it.

We also examine what aspects of a digital service actually provide value to the end user, as establishing where resources and effort are wasted – digital waste – reveals what can be cut out. For example, MP3 audio compression works by removing frequencies that are inaudible or less audible to the human ear – shrinking the size of the file for minimal loss of audible quality.

This is no small task. Estimates have put the technology sector’s global carbon footprint at roughly 2% of worldwide emissions – almost as much as that generated by aviation. But there is a big difference: IT is a more pervasive, and in some ways more democratic, technology. Perhaps 6% or so of the world’s population will fly in a given year, while around 40% have access to the internet at home. More than a billion people have Facebook accounts. Digital technology and the online services it provides are used by far more of us, and far more often.

Fort McMurray and the fires of climate change

Elizabeth Kolbert writes: No one knows exactly how the fire began — whether it was started by a lightning strike or by a spark provided by a person — but it’s clear why the blaze, once under way, raged out of control so quickly. Alberta experienced an unusually dry and warm winter. Precipitation was low, about half of the norm, and what snow there was melted early. April was exceptionally mild, with temperatures regularly in the seventies; two days ago, the thermometer hit ninety, which is about thirty degrees higher than the region’s normal May maximum. “You hate to use the ​cliché, but it really was kind of a perfect storm,” Mike Wotton, a research scientist with the Canadian Forest Service, told the CBC.

Though it’s tough to pin any particular disaster on climate change, in the case of Fort McMurray the link is pretty compelling. In Canada, and also in the United States and much of the rest of the world, higher temperatures have been extending the wildfire season. Last year, wildfires consumed ten million acres in the U.S., which was the largest area of any year on record. All of the top five years occurred in the past decade. In some areas, “we now have year-round fire seasons,” Matt Jolly, a research ecologist for the United States Forest Service, recently told the Times.

“You can say it couldn’t get worse,” Jolly added, but based on its own projections, the forest service expects that it will get worse. According to a Forest Service report published last April, “Climate change has led to fire seasons that are now on average 78 days longer than in 1970.” Over the past three decades, the area destroyed each year by forest fires has doubled, and the service’s scientists project that it’s likely to “double again by midcentury.” A group of scientists who analyzed lake cores from Alaska to obtain a record of forest fires over the past ten thousand years found that, in recent decades, blazes were both unusually frequent and unusually severe. “This extreme combination suggests a transition to a unique regime of unprecedented fire activity,” they concluded.

All of this brings us to what one commentator referred to as “the black irony” of the fire that has destroyed most of Fort McMurray.

The town exists to get at the tar sands, and the tar sands produce a particularly carbon-intensive form of fuel. (The fight over the Keystone XL pipeline is, at its heart, a fight over whether the U.S. should be encouraging — or, if you prefer, profiting from — the exploitation of the tar sands.) The more carbon that goes into the atmosphere, the warmer the world will get, and the more likely we are to see devastating fires like the one now raging. [Continue reading…]

Bloomberg reports: Wildfires raging through Alberta have spread to the main oil-sands facilities north of Fort McMurray, knocking out an estimated 1 million barrels of production from Canada’s energy hub. Fire officials say the out-of-control inferno may keep burning for months without significant rainfall.

The blaze, forecast to expand to more than 2,500 square kilometers (965 square miles) in the next few days, made an “unexpected” move to the north Saturday, rapidly encroaching bitumen mining operations run by Suncor Energy Inc. and Syncrude Canada Ltd. The fires may soon cover an area the size of Luxembourg.

“It is a dangerous and unpredictable and vicious fire that is feeding off an extremely dry Boreal forest,” federal Public Safety Minister Ralph Goodale told reporters Saturday in Regina, Saskatchewan. He said the swirling fire is not yet a threat to any additional communities.

The wildfires have led to combined productions cuts of more than 1 million barrels of oil a day, or about 40 percent of the region’s output of 2.5 million barrels, based on IHS Energy estimates. The cuts, and the mass exodus of more than 80,000 people from the fires raging in Fort McMurray, represent another blow to an economy already mired in recession from the oil price collapse. [Continue reading…]

The Los Angeles Times reports: Though the cause of the fire has not been determined, the inferno has become symbolic of the tension within Canada over its role in climate change.

Some Canadians see the fire as nature lashing back at those who mistreat it in the name of profit.

Others see the hard science: a wildfire formed in conditions consistent with climate change striking with academic irony, not vengeance, in a place that helps supply the world with a fossil fuel. The evacuees were really climate refugees, they say.

Still others view it as just very bad luck, a setback the oil industry will find a way to overcome.

The debate reflects a country wrestling within itself at a difficult moment — and it is testing that famous Canadian civility.

A provincial politician who called the fire “karmic” was quickly castigated and later apologized. When Canadian Green Party leader Elizabeth May said the fire was “very related to the global climate crisis,” Prime Minister Justin Trudeau suggested she was making “a political argument.”

Some environmentalists have been accused of lecturing to or, worse, condemning people who have lost everything. In Fort McMurray, more than 2,000 structures were consumed by the flames.

“I wish I could kick every person posting ‘That’s what you get for living by the oil sands’ comments,” a young Edmonton woman tweeted Tuesday evening at the peak of the evacuation, when flames were whipping across Highway 63, the only road out of Fort McMurray. “You’re terrible people.”

Janet Keeping, the Green Party leader within Alberta, was among several people who invoked climate change early in the week — and did so without clearly expressing support for fire victims. She soon tried to strike a new chord.

“Caring about people means caring about #climatechange,” Keeping wrote Thursday on Twitter.

Alberta’s oil sands are said to hold the third largest reserves in the world, after Saudi Arabia and Venezuela. They made Alberta rich even as they have made Canada uneasy.

Conservation groups have long despised the intensive extraction process involved in gleaning crude from the sands — Alberta would have been the source for the Keystone XL oil pipeline that President Obama rejected last year — and many Canadians loathe what they view as an excessively capitalist culture in Fort McMurray.

Lakota lead the fight against the Dakota Access Pipeline

Jason Coppola reports: As the start of 2016 shatters last year’s record as the hottest year on record, the Oceti Sakowin (Seven Council Fires of the Great Sioux Nation) once again find themselves on the front lines of the battle against the fossil fuel industry.

Members of the Standing Rock Sioux Tribe have established a Spirit Camp at the mouth of the Cannonball River in North Dakota as a means of bringing attention and awareness to a proposed pipeline and act as an enduring symbol of resistance against its construction.

The Dakota Access Pipeline (DAPL) is set to cut through several US states, delivering hundreds of thousands of barrels of crude oil from the Bakken and Three Forks oil fields in North Dakota to Patoka, Illinois.

The Dallas-based Energy Transfer Partners pipeline will cross the Ogallala Aquifer — a million-year-old shallow water table spanning eight US states, which provides fresh water for drinking and agriculture — while twice crossing the Missouri River and running alongside the Standing Rock Indian Reservation.

A spill could contaminate the Ogallala Aquifer, one of the worlds largest, which is already in crisis and under threat of running dry in the coming decades. [Continue reading…]

Why it’s impossible to actually be a vegetarian

By Andrew Smith, Drexel University

In case you’ve forgotten the section on the food web from high school biology, here’s a quick refresher.

Plants make up the base of every food chain of the food web (also called the food cycle). Plants use available sunlight to convert water from the soil and carbon dioxide from the air into glucose, which gives them the energy they need to live. Unlike plants, animals can’t synthesize their own food. They survive by eating plants or other animals.

Clearly, animals eat plants. What’s not so clear from this picture is that plants also eat animals. They thrive on them, in fact (just Google “fish emulsion”). In my new book, “A Critique of the Moral Defense of Vegetarianism,” I call it the transitivity of eating. And I argue that this means one can’t be a vegetarian.

The creatures that remember Chernobyl

Ron Broglio writes: Radioactive, wild boar are invading towns in southern Germany. They travel in packs scavenging for food. They break through fences and roam the roads shutting down highway traffic. They take down a man in a wheelchair. Police scramble to restore order in urban centers. The boar are armed with a post-apocalyptic payload: Radioactive fallout from the 1986 Chernobyl nuclear disaster, which marks its thirtieth anniversary today. By foraging on radioactive plants, the animals embody the return of a disaster many seek to repress.

After the collapse and meltdown of a reactor at Chernobyl, over a hundred thousand people were evacuated from a 30-kilometer Exclusion Zone around the nuclear power plant. Residents exposed to the ensuing radiation suffered from leukemia, thyroid cancer, and other maladies. Some 4,000 people could die from illnesses related to the accident.

In the three decades since, a range of animals have taken up residence in the Exclusion Zone. They thrive in this occasionally mutant, non-human world where radiation remains 10 to 100 times higher than is safe for human occupancy. Rare species not seen in the region for hundreds of years have returned, including the Przewalski’s horse, the European bison, the lynx, and the Eurasian brown bear. Without fear of being hunted, the animals roam the forest and the ruins of cities in what has become an eerily post-human wildlife sanctuary. [Continue reading…]

Being (almost) eaten alive can make you a diehard environmentalist

Becca Cudmore writes: In his Oscar acceptance speech, Leonardo DiCaprio said, “Making The Revenant was about man’s relationship to the natural world.” Perhaps the film’s most gripping illustration of this was when a grizzly bear nearly mauls DiCaprio’s character, an American fur trapper, to death. To be eaten by a predator, after all, may be the most apt display of man’s vulnerable state in nature. Onstage, DiCaprio evoked that vulnerable state, and made a forceful plea for global climate change action.

It turns out this isn’t the first time a near-fatal mauling has emboldened an environmentalist’s perspective. In 1985, the late philosopher Val Plumwood was nearly eaten by a saltwater crocodile. The harrowing experience inspired her to begin writing The Eye of the Crocodile, a series of essays posthumously published in 2012. In its first and most riveting piece, “Being Prey,” she explains how her critique of anthropocentrism — the idea that humans stand apart from nature — became palpable.

Plumwood was paddling through Australia’s Kakadu National Park in a 14-foot canoe in search of an Aboriginal rock art site. The hours passed, rain mounted, and she had found herself deep in a channel surrounded by steep mud banks and snags. When a sandy bar caused her to stop completely, she stepped out of the canoe and recalled how park owners had warned her of crocodiles hunting at the water’s edge. She paddled back into the main current and, rounding a bend, “saw in midstream what looked like a floating stick.” As the current moved Plumwood farther forward, “the stick developed eyes.” As the animal struck the canoe, she instinctively leapt onto the bank, into the lower branches of a paperbark tree. “But before my foot even tripped the first branch, I had a blurred, incredulous vision of great toothed jaws bursting from the water,” she writes.

30 years after Chernobyl disaster, containment nears completion but authorities turn a blind eye to logging

The Washington Post reports: An international effort to seal the destroyed remains of the nuclear reactor that exploded in Ukraine 30 years ago is finally close to completion, and remarkably, considering the political revolution and armed conflict that have rocked the country since 2014, it’s close to being on schedule.

The completion of the New Safe Confinement, often called the “arch,” could contain the radiation from mankind’s worst nuclear catastrophe for a century, says the European Bank for Reconstruction and Development, which has led the project. But it will also mark a handover to Ukraine’s fractious and underfunded authorities, who are expected to tackle future waste management at their own expense.

That may not reassure Nadiya Makyrevych.

For three decades, she has been living with the consequences of Chernobyl explosion. She can recall that morning in late April 1986, and the small signs that something was wrong in the workers’ town where she lived: the tinny, metallic taste in her mouth. The way her 6-month-old daughter slept so deeply after breast-feeding. [Continue reading…]

The New York Times reports: The road through the forest, abandoned, is at times barely discernible, covered with the debris of fallen tree limbs, vines, leaves and moss pushing up through cracks in the crumbling asphalt.

The moss is best avoided, says our guide, Artur N. Kalmykov, a young Ukrainian who has made a hobby of coming here to the exclusion zone surrounding the nuclear reactor at Chernobyl, set aside in perpetuity after the catastrophe in 1986. It can be radioactive, having carried buried radiation to the surface as it grew.

Above all, he says, watch out for windblown dust, which could well be laced with deadly plutonium.

Despite the dangers — which are actually minimal these days, except when the wind is howling — and the risk of arrest, Mr. Kalmykov is at home here. “In Kiev my head is full,” he said. “Here I can relax. I could hang out in Kiev. But this is more interesting.”

What Mr. Kalmykov and fellow unofficial explorers of the Chernobyl zone, members of a peculiar subculture who are in their 20s and call themselves “the stalkers,” have found is more interesting still: vast tracts of clear-cutting in the ostensibly protected forest. [Continue reading…]

In much of Europe, walking wherever you want is perfectly legal. Not in America

mt-tam

Ken Ilgunas writes: A couple of years ago, I trespassed across America. I’d set out to hike the proposed route of the Keystone XL pipeline, which had been planned to stretch over a thousand miles over the Great Plains, from Alberta, Canada, to the Gulf Coast. To walk the pipe’s route, roads wouldn’t do. I’d have to cross fields, hop barbed-wire fences and camp in cow pastures — much of it on private property.

I’d figured that walking across the heartland would probably be unlawful, unprecedented and a little bit crazy. We Americans, after all, are forbidden from entering most of our private lands. But in some European countries, walking almost wherever you want is not only ordinary but perfectly acceptable.

In Sweden, they call it “allemansrätt.” In Finland, it’s “jokamiehenoikeus.” In Scotland, it’s “the right to roam.” Germany allows walking through privately owned forests, unused meadows and fallow fields. In 2000, England and Wales passed the Countryside and Rights of Way Act, which gave people access to “mountain, moor, heath or down.” [Continue reading…]

World heading for catastrophe over natural disasters, risk expert warns

The Guardian reports: The world’s failure to prepare for natural disasters will have “inconceivably bad” consequences as climate change fuels a huge increase in catastrophic droughts and floods and the humanitarian crises that follow, the UN’s head of disaster planning has warned.

Last year, earthquakes, floods, heatwaves and landslides left 22,773 people dead, affected 98.6 million others and caused $66.5bn (£47bn) of economic damage (pdf). Yet the international community spends less than half of one per cent of the global aid budget on mitigating the risks posed by such hazards.

Robert Glasser, the special representative of the secretary general for disaster risk reduction, said that with the world already “falling short” in its response to humanitarian emergencies, things would only get worse as climate change adds to the pressure. [Continue reading…]

Fate of world’s coastlines rests on melting Antarctic ice

marshland

John Upton writes: Councilmembers of an island town in Georgia met in a police station near sandy beaches last week to mull a plan for coping with worsening floods. The meeting followed unprecedented king tide floods in the fall that inundated the island and nearby Savannah, and shut down the highway that connects them.

“We’ve had more frequent flooding in areas that haven’t flooded before,” said Jason Buelterman, mayor of the beach town on the eastern shore of Tybee Island, where the population of a few thousand residents swells each summer with vacationers. “In November, water was coming into people’s garages and stuff. It had never happened before.”

The meeting was held eight days before world leaders were due to converge in New York this Friday to ratify a United Nations treaty, aiming to avert the worst impacts of climate change. If the treaty succeeds, Tybee Island and other coastal communities may flood terribly in the coming decades, but will most likely remain mostly above sea level, recent Antarctic modeling suggests. Vast scientific uncertainties, however, mean even that cannot be assured.

Mayors from small towns, planners from the world’s largest cities and U.N. diplomats are being guided on the details of a looming coastal crisis by sea level projections compiled by a U.N. science panel. The panel’s work includes warnings about the amount of flooding that could be caused by melting in Antarctica, and those warnings have been growing bleaker.

The barren continent — the planet’s greatest reservoir of ice — remains shrouded in frigid mystery, and a lack of scientific knowledge about its ice sheet means scientists can’t yet predict how much flooding it could cause as temperatures continue to climb. A recent study, though, added to concerns that it could begin disintegrating, inundating coastal neighborhoods around the world, unless the heady goals of the new U.N. climate pact are achieved.

The Intergovernmental Panel on Climate Change’s most recent findings, from three years ago, appear to have underestimated the potential seriousness of the Antarctic problem, with sweeping implications for the urgency of pollution cuts — and for the futures of coastal communities like Tybee Island’s.

Instead of the anticipated several feet of sea level rise this century if current pollution rates continue, the latest modeling-based science warns that melting could lead to twice that amount. That sobering estimate is a rough one. [Continue reading…]

Aurora Borealis viewed from the International Space Station

Live Science reports: Auroras are produced when solar particles that are ejected from the sun and carried to Earth by solar winds collide with electrically charged particles in Earth’s magnetic field, triggering reactions in the upper atmosphere that release light.

They are most commonly glimpsed on Earth at high latitudes, in the Northern and Southern hemispheres. While auroras are typically green, they can also appear violet, red, blue, while or pink, according to NASA.

To produce the auroras video, NASA partnered with media infrastructure experts at Harmonic, with whom they also launched a new UHD channel featuring 4K content — the first noncommercial UHD channel in North America — the agency said in a statement. [Continue reading…]

Oil industry knew of ‘serious’ climate concerns more than 45 years ago

The Guardian reports: The oil industry’s knowledge of dangerous climate change stretches back to the 1960s, with unearthed documents showing that it was warned of “serious worldwide environmental changes” more than 45 years ago.

The Stanford Research Institute presented a report to the American Petroleum Institute (API) in 1968 that warned the release of carbon dioxide from burning fossil fuels could carry an array of harmful consequences for the planet.

The emergence of this stark advice follows a series of revelations that the fossil fuel industry was aware of climate change for decades, only to publicly deny its scientific basis.

“Significant temperature changes are almost certain to occur by the year 2000 and these could bring about climatic change,” the 1968 Stanford report, found and republished by the Center for International Environmental Law, states. “If the Earth’s temperature increases significantly, a number of events might be expected to occur including the melting of the Antarctic ice cap, a rise in sea levels, warming of the oceans and an increase in photosynthesis.

“It is clear that we are unsure as to what our long-lived pollutants are doing to our environment; however, there seems to be no doubt that the potential damage to our environment could be severe.” [Continue reading…]

Climate-related death of coral around world alarms scientists

bleached-coral

The New York Times reports: Kim Cobb, a marine scientist at the Georgia Institute of Technology, expected the coral to be damaged when she plunged into the deep blue waters off Kiritimati Island, a remote atoll near the center of the Pacific Ocean. Still, she was stunned by what she saw as she descended some 30 feet to the rim of a coral outcropping.

“The entire reef is covered with a red-brown fuzz,” Dr. Cobb said when she returned to the surface after her recent dive. “It is otherworldly. It is algae that has grown over dead coral. It was devastating.”

The damage off Kiritimati is part of a mass bleaching of coral reefs around the world, only the third on record and possibly the worst ever. Scientists believe that heat stress from multiple weather events including the latest severe El Niño, compounded by climate change, has threatened more than a third of Earth’s coral reefs. Many may not recover.

Coral reefs are the crucial incubators of the ocean’s ecosystem, providing food and shelter to a quarter of all marine species, and they support fish stocks that feed more than one billion people. They are made up of millions of tiny animals, called polyps, that form symbiotic relationships with algae, which in turn capture sunlight and carbon dioxide to make sugars that feed the polyps.

An estimated 30 million small-scale fishermen and women depend on reefs for their livelihoods, more than one million in the Philippines alone. In Indonesia, fish supported by the reefs provide the primary source of protein.

“This is a huge, looming planetary crisis, and we are sticking our heads in the sand about it,” said Justin Marshall, the director of CoralWatch at Australia’s University of Queensland. [Continue reading…]

How to count trees

Zach St. George writes: Gregor Hintler had what seemed like a simple question: How many trees are there? As part of Plant for the Planet, a youth initiative that aimed to plant one billion trees in every country by 2020, he needed a way to figure out how many trees the planet could fit. But when he tried to find out, he realized nobody knew the answer. One estimate suggested 400 billion trees. “That sounds like a lot,” he recalls thinking. “Could be right.” But Hintler, who was then a graduate student in environmental management at Yale University, started looking at data from plots in Germany, Norway, and the United States, where foresters had counted the number of trees. He discovered that the old figures weren’t even close — 400 billion was, in fact, far too low.

Forests cover about one third of the planet’s terrestrial area. They prevent desertification and erosion, store carbon, and provide habitat for millions of species. The recent Paris climate agreement highlights their importance, recommending that signing countries take steps to slow deforestation and enlist their forests in carbon credit markets. Knowing how many trees there are now, and how many there used to be, will help researchers assess human impact on the planet and any options going forward. [Continue reading…]

Human influence on the planet is so profound – and terrifying – it will leave its legacy for millennia

decay1

Robert Macfarlane writes: In 2003 the Australian philosopher Glenn Albrecht coined the term solastalgia to mean a “form of psychic or existential distress caused by environmental change”. Albrecht was studying the effects of long-term drought and large-scale mining activity on communities in New South Wales, when he realised that no word existed to describe the unhappiness of people whose landscapes were being transformed about them by forces beyond their control. He proposed his new term to describe this distinctive kind of homesickness.

Where the pain of nostalgia arises from moving away, the pain of solastalgia arises from staying put. Where the pain of nostalgia can be mitigated by return, the pain of solastalgia tends to be irreversible. Solastalgia is not a malady specific to the present – we might think of John Clare as a solastalgic poet, witnessing his native Northamptonshire countryside disrupted by enclosure in the 1810s – but it has flourished recently. “A worldwide increase in ecosystem distress syndromes,” wrote Albrecht, is “matched by a corresponding increase in human distress syndromes”. Solastalgia speaks of a modern uncanny, in which a familiar place is rendered unrecognisable by climate change or corporate action: the home become suddenly unhomely around its inhabitants.

Albrecht’s coinage is part of an emerging lexis for what we are increasingly calling the “Anthropocene”: the new epoch of geological time in which human activity is considered such a powerful influence on the environment, climate and ecology of the planet that it will leave a long-term signature in the strata record. And what a signature it will be. We have bored 50m kilometres of holes in our search for oil. We remove mountain tops to get at the coal they contain. The oceans dance with billions of tiny plastic beads. Weaponry tests have dispersed artificial radionuclides globally. The burning of rainforests for monoculture production sends out killing smog-palls that settle into the sediment across entire countries. We have become titanic geological agents, our legacy legible for millennia to come. [Continue reading…]
