A Global and Imperiled Treasure

Trail Ridge Road RMNP 2

About 25 miles from where I write lies Colorado’s Rocky Mountain National Park (RMNP). It’s a gorgeous part of the world — pristine forests, blue alpine lakes, frigid streams and ragged peaks. Luckily thanks to the persistent work of Enos Mills and President Woodrow Wilson’s signature RMNP has been protected from development and destruction since 1915. So too are its 411 sister regions and monuments that now make up the US National Park System.

The nationwide park system was officially founded 100 years ago today, August 25, 1916. It is a precious and priceless jewel — truly one of America’s best ideas.

On this centenary we should be reminded that each one of our parks and monuments requires our constant and vigilant protection. We must do all that we can to ensure that our children and their children can experience for themselves — over the next 100 years (and beyond) — some of nature’s true wonders.

Though keep in mind that while our parks may be protected from direct human exploitation they’re not immune to the ravages of climate change.

From the Guardian:

After a century of shooing away hunters, tending to trails and helping visitors enjoy the wonder of the natural world, the guardians of America’s most treasured places have been handed an almost unimaginable new job – slowing the all-out assault climate change is waging against national parks across the nation.

As the National Parks Service (NPS) has charted the loss of glaciers, sea level rise and increase in wildfires spurred by rising temperatures in recent years, the scale of the threat to US heritage across the 412 national parks and monuments has become starkly apparent.

As the National Parks Service turns 100 this week, their efforts to chart and stem the threat to the country’s history faces a daunting task. America’s grand symbols and painstakingly preserved archaeological sites are at risk of being winnowed away by the crashing waves, wildfires and erosion triggered by warming temperatures.

The Statue of Liberty is at “high exposure” risk from increasingly punishing storms. A national monument dedicated to abolitionist Harriet Tubman, who will be enshrined on a new $20 note, could be eaten away by rising tides in Maryland. The land once walked by Pocahontas and Captain John Smith in Jamestown, the first English settlement in the US, is surrounded by waters rising at twice the global average and may be beyond rescue.

These threats are the latest in a pile of identified calamities to befall national parks and monuments due to climate change. Receding ice, extreme heat and acidifying oceans are morphing America’s landscapes and coasts at a faster pace than at any time in human history.

“Yosemite’s famous glacier, once a mile wide, is almost gone,” fretted Barack Obama during a visit to the vast park in June.

“Rising temperatures could mean no more glaciers in Glacier national park, no more Joshua trees in Joshua Tree national park.

“Rising seas can destroy vital ecosystems in the Everglades and at some point could even threaten icons like the Statue of Liberty and Ellis Island. That’s not the America I want to pass on to the next generation.”

Change, however, is inevitable no matter how quickly greenhouse gas emissions are cut. An NPS study from 2014 found four in five of America’s national parks are now at the “extreme end” of temperature variables charted since 1901.

“We are starting to see things spiral away now,” said Gregor Schuurman, an ecologist at the NPS climate change response program. “We are going to look back at this time and actually think it was a calm period. And then people will start asking questions about what we were doing about the situation.”

H2O and IQ

There is great irony in NASA’s recent discovery of water flowing on Mars.

First, that the gift of our intelligence allows us to make such amazing findings on other worlds while we use the same brain cells to enable the rape and pillage of our own.

Second, the meager seasonal trickles of liquid on the martian surface show us a dire possible future for our own planet.

Mars-Recurring-Slope-Lineae

From the Guardian:

Evidence for flowing water on Mars: this opens up the possibility of life, of wonders we cannot begin to imagine. Its discovery is an astonishing achievement. Meanwhile, Martian scientists continue their search for intelligent life on Earth.

We may be captivated by the thought of organisms on another planet, but we seem to have lost interest in our own. The Oxford Junior Dictionary has been excising the waymarks of the living world. Adders, blackberries, bluebells, conkers, holly, magpies, minnows, otters, primroses, thrushes, weasels and wrens are now surplus to requirements.

In the past four decades, the world has lost 50% of its vertebrate wildlife. But across the latter half of this period, there has been a steep decline in media coverage. In 2014, according to a study at Cardiff University, there were as many news stories broadcast by the BBC and ITV about Madeleine McCann (who went missing in 2007) as there were about the entire range of environmental issues.

Think of what would change if we valued terrestrial water as much as we value the possibility of water on Mars. Only 3% of the water on this planet is fresh; and of that, two-thirds is frozen. Yet we lay waste to the accessible portion. Sixty per cent of the water used in farming is needlessly piddled away by careless irrigation. Rivers, lakes and aquifers are sucked dry, while what remains is often so contaminated that it threatens the lives of those who drink it. In the UK, domestic demand is such that the upper reaches of many rivers disappear during the summer. Yet still we install clunky old toilets and showers that gush like waterfalls.

As for salty water, of the kind that so enthrals us when apparently detected on Mars, on Earth we express our appreciation with a frenzy of destruction. A new report suggests fish numbers have halved since 1970. Pacific bluefin tuna, which once roamed the seas in untold millions, have been reduced to an estimated 40,000, yet still they are pursued. Coral reefs are under such pressure that most could be gone by 2050. And in our own deep space, our desire for exotic fish rips through a world scarcely better known to us than the red planet’s surface. Trawlers are now working at depths of 2,000 metres. We can only guess at what they could be destroying.

A few hours before the Martian discovery was announced, Shell terminated its Arctic oil prospecting in the Chukchi Sea. For the company’s shareholders, it’s a minor disaster: the loss of $4bn; for those who love the planet and the life it sustains, it is a stroke of great fortune. It happened only because the company failed to find sufficient reserves. Had Shell succeeded, it would have exposed one of the most vulnerable places on Earth to spills, which are almost inevitable where containment is almost impossible. Are we to leave such matters to chance?

At the beginning of September, two weeks after he granted Shell permission to drill in the Chukchi Sea, Barack Obama travelled to Alaska to warn Americans about the devastating effects that climate change caused by the burning of fossil fuels could catalyse in the Arctic. “It’s not enough just to talk the talk”, he told them. “We’ve got to walk the walk.” We should “embrace the human ingenuity that can do something about it”. Human ingenuity is on abundant display at Nasa, which released those astounding images. But not when it comes to policy.

Let the market decide: this is the way in which governments seek to resolve planetary destruction. Leave it to the conscience of consumers, while that conscience is muted and confused by advertising and corporate lies. In a near-vacuum of information, we are each left to decide what we should take from other species and other people, what we should allocate to ourselves or leave to succeeding generations. Surely there are some resources and some places – such as the Arctic and the deep sea – whose exploitation should simply stop?

Conservative Dogma and Climate Science and Social Justice

The_Earth_seen_from_Apollo_17

You would not be correct in labeling the Catholic Church a hotbed of progressive thought. It’s very foundation is steeped in tradition and dogma. So, you could be forgiven for thinking that most secular politicians in the United States, of all stripes, would have a better grasp of current realities and even science than an establishment conservative church.

Yet, the Vatican has just released a new papal encyclical, On Care For Our Common Home, on the environment that decries the ecological and humanitarian crisis wrought by climate change. You read this correctly — the pope seems to understand and embrace the science of climate change and the impact of humans. In addition to acceptance of scientific principle the encyclical paints our ongoing destruction of the planet and its climate as an issue of social justice. The pope is absolutely correct — the poor suffer unequally from the strife enabled and enacted by the rich.

Ironically, many of the pope’s Republican followers — let’s call them crusading climate science deniers — in the US Congress are of another mind. They’ve been quite vociferous of late, arguing that the pope would best serve his flock by sticking to communion and keeping his nose out of scientific, environmental and political debate. I used to think that most Republicans, including Catholics, derived their denial of climate science — and perhaps most science — from a strict devotion to their god. But, now that one of God’s representatives on Earth backs mainstream climate science what are the Republican believers to do?

One day after Pope Francis released this sweeping document, former Florida Governor Jeb Bush, a Republican and Catholic, had this to say:

“… I don’t get economic policy from my bishops or my cardinals or my pope.” 

Par for the course. One wonders where Governor Bush, Senator Inhofe and their colleagues actually do get there economic policy, and more importantly where do they learn about science, if any at all. We’ll have to leave the issue of social justice aside for now — one battle at a time.

Dear God, you do work in such mysterious ways!

An excerpt below from the Vatican’s encyclical on the environment. Read it in full here.

The Earth, our home, is beginning to look more and more like an immense pile of filth. In many parts of the planet, the elderly lament that once beautiful landscapes are now covered with rubbish. Industrial waste and chemical products utilised in cities and agricultural areas can lead to bioaccumulation in the organisms of the local population, even when levels of toxins in those places are low. Frequently no measures are taken until after people’s health has been irreversibly affected.

These problems are closely linked to a throwaway culture which affects the excluded just as it quickly reduces things to rubbish. To cite one example, most of the paper we produce is thrown away and not recycled. It is hard for us to accept that the way natural ecosystems work is exemplary: plants synthesise nutrients which feed herbivores; these in turn become food for carnivores, which produce significant quantities of organic waste which give rise to new generations of plants. But our industrial system, at the end of its cycle of production and consumption, has not developed the capacity to absorb and reuse waste and by-products. We have not yet managed to adopt a circular model of production capable of preserving resources for present and future generations, while limiting as much as possible the use of non-renewable resources, moderating their consumption, maximizing their efficient use, reusing and recycling them. A serious consideration of this issue would be one way of counteracting the throwaway culture which affects the entire planet, but it must be said that only limited progress has been made in this regard.

The climate is a common good, belonging to all and meant for all. At the global level, it is a complex system linked to many of the essential conditions for human life. A very solid scientific consensus indicates that we are presently witnessing a disturbing warming of the climatic system. In recent decades this warming has been accompanied by a constant rise in the sea level and, it would appear, by an increase of extreme weather events, even if a scientifically determinable cause cannot be assigned to each particular phenomenon. Humanity is called to recognise the need for changes of lifestyle, production and consumption, in order to combat this warming or at least the human causes which produce or aggravate it. It is true that there are other factors (such as volcanic activity, variations in the Earth’s orbit and axis, the solar cycle), yet a number of scientific studies indicate that most global warming in recent decades is due to the great concentration of greenhouse gases (carbon dioxide, methane, nitrogen oxides and others) released mainly as a result of human activity. Concentrated in the atmosphere, these gases do not allow the warmth of the sun’s rays reflected by the Earth to be dispersed in space. The problem is aggravated by a model of development based on the intensive use of fossil fuels, which is at the heart of the worldwide energy system. Another determining factor has been an increase in changed uses of the soil, principally deforestation for agricultural purposes.

Many of those who possess more resources and economic or political power seem mostly to be concerned with masking the problems or concealing their symptoms, simply making efforts to reduce some of the negative impacts of climate change. However, many of these symptoms indicate that such effects will continue to worsen if we continue with current models of production and consumption. There is an urgent need to develop policies so that, in the next few years, the emission of carbon dioxide and other highly polluting gases can be drastically reduced, for example, substituting for fossil fuels and developing sources of renewable energy. Worldwide there is minimal access to clean and renewable energy. There is still a need to develop adequate storage technologies. Some countries have made considerable progress, although it is far from constituting a significant proportion. Investments have also been made in means of production and transportation which consume less energy and require fewer raw materials, as well as in methods of construction and renovating buildings which improve their energy efficiency. But these good practices are still far from widespread.

The human environment and the natural environment deteriorate together; we cannot adequately combat environmental degradation unless we attend to causes related to human and social degradation. In fact, the deterioration of the environment and of society affects the most vulnerable people on the planet: both everyday experience and scientific research show that the gravest effects of all attacks on the environment are suffered by the poorest. For example, the depletion of fishing reserves especially hurts small fishing communities without the means to replace those resources; water pollution particularly affects the poor who cannot buy bottled water; and rises in the sea level mainly affect impoverished coastal populations who have nowhere else to go. The impact of present imbalances is also seen in the premature death of many of the poor, in conflicts sparked by the shortage of resources, and in any number of other problems which are insufficiently represented on global agendas. It needs to be said that, generally speaking, there is little in the way of clear awareness of problems which especially affect the excluded. Yet they are the majority of the planet’s population, billions of people.

Climate Change Denial: English Only

It’s official. Native English-speakers are more likely to be in denial over climate change than non-English speakers. In fact, many who do not see a human hand in our planet’s environmental and climatic troubles are located in the United States, Britain,  Australia and Canada. Enough said, in English.

Sacre bleu!

Now, the Guardian would have you believe that media monopolist — Rupert Murdoch — is behind the climate change skeptics and deniers. After all, he is well known for his views on climate and his empire controls large swathes of the media that most English-speaking people consume.  However, it’s probably a little more complicated.

From the Guardian:

Here in the United States, we fret a lot about global warming denial. Not only is it a dangerous delusion, it’s an incredibly prevalent one. Depending on your survey instrument of choice, we regularly learn that substantial minorities of Americans deny, or are sceptical of, the science of climate change.

The global picture, however, is quite different. For instance, recently the UK-based market research firm Ipsos MORI released its “Global Trends 2014” report, which included a number of survey questions on the environment asked across 20 countries. (h/t Leo Hickman). And when it came to climate change, the result was very telling.

Note that these results are not perfectly comparable across countries, because the data were gathered online, and Ipsos MORI cautions that for developing countries like India and China, “the results should be viewed as representative of a more affluent and ‘connected’ population.”

Nonetheless, some pretty significant patterns are apparent. Perhaps most notably: Not only is the United States clearly the worst in its climate denial, but Great Britain and Australia are second and third worst, respectively. Canada, meanwhile, is the seventh worst.

What do these four nations have in common? They all speak the language of Shakespeare.

Why would that be? After all, presumably there is nothing about English, in and of itself, that predisposes you to climate change denial. Words and phrases like “doubt,” “natural causes,” “climate models,” and other sceptic mots are readily available in other languages. So what’s the real cause?

One possible answer is that it’s all about the political ideologies prevalent in these four countries.

The US climate change counter movement is comprised of 91 separate organizations, with annual funding, collectively, of “just over $900 million.” And they all speak English.

“I do not find these results surprising,” says Riley Dunlap, a sociologist at Oklahoma State University who has extensively studied the climate denial movement. “It’s the countries where neo-liberalism is most hegemonic and with strong neo-liberal regimes (both in power and lurking on the sidelines to retake power) that have bred the most active denial campaigns—US, UK, Australia and now Canada. And the messages employed by these campaigns filter via the media and political elites to the public, especially the ideologically receptive portions.” (Neoliberalism is an economic philosophy centered on the importance of free markets and broadly opposed to big government interventions.)

Indeed, the English language media in three of these four countries are linked together by a single individual: Rupert Murdoch. An apparent climate sceptic or lukewarmer, Murdoch is the chairman of News Corp and 21st Century Fox. (You can watch him express his climate views here.) Some of the media outlets subsumed by the two conglomerates that he heads are responsible for quite a lot of English language climate scepticism and denial.

In the US, Fox News and the Wall Street Journal lead the way; research shows that Fox watching increases distrust of climate scientists. (You can also catch Fox News in Canada.) In Australia, a recent study found that slightly under a third of climate-related articles in 10 top Australian newspapers “did not accept” the scientific consensus on climate change, and that News Corp papers — the Australian, the Herald Sun, and the Daily Telegraph — were particular hotbeds of scepticism. “TheAustralian represents climate science as matter of opinion or debate rather than as a field for inquiry and investigation like all scientific fields,” noted the study.

And then there’s the UK. A 2010 academic study found that while News Corp outlets in this country from 1997 to 2007 did not produce as much strident climate scepticism as did their counterparts in the US and Australia, “the Sun newspaper offered a place for scornful sceptics on its opinion pages as did The Times and Sunday Times to a lesser extent.” (There are also other outlets in the UK, such as the Daily Mail, that feature plenty of scepticism but aren’t owned by News Corp.)

Thus, while there may not be anything inherent to the English language that impels climate denial, the fact that English language media are such a major source of that denial may in effect create a language barrier.

And media aren’t the only reason that denialist arguments are more readily available in the English language. There’s also the Anglophone nations’ concentration of climate “sceptic” think tanks, which provide the arguments and rationalisations necessary to feed this anti-science position.

According to a study in the journal Climatic Change earlier this year, the US is home to 91 different organisations (think tanks, advocacy groups, and trade associations) that collectively comprise a “climate change counter-movement.” The annual funding of these organisations, collectively, is “just over $900 million.” That is a truly massive amount of English-speaking climate “sceptic” activity, and while the study was limited to the US, it is hard to imagine that anything comparable exists in non-English speaking countries.

Asimov Fifty Years On

1957-driverless-car

In 1964, Isaac Asimov wrote an essay for the New York Times entitled, Visit the World’s Fair in 2014. The essay was a free-wheeling opinion of things to come, viewed through the lens of New York’s World’s Fair of 1964. The essay shows that even a grand master of science fiction cannot predict the future — he got some things quite right and other things rather wrong. Some examples below, and his full essay are below.

That said, what has captured recent attention is Asimov’s thinking on the complex and evolving relationship between humans and technology, and the challenges of environmental stewardship in an increasingly over-populated and resource-starved world.

So, while Asimov was certainly not a teller of fortunes, we had many insights that many, even today, still lack.

Read the entire Isaac Asimov essay here.

What Asimov got right:

“Communications will become sight-sound and you will see as well as hear the person you telephone.”

“As for television, wall screens will have replaced the ordinary set…”

“Large solar-power stations will also be in operation in a number of desert and semi-desert areas…”

“Windows… will be polarized to block out the harsh sunlight. The degree of opacity of the glass may even be made to alter automatically in accordance with the intensity of the light falling upon it.”

What Asimov got wrong:

“The appliances of 2014 will have no electric cords, of course, for they will be powered by long- lived batteries running on radioisotopes.”

“…cars will be capable of crossing water on their jets…”

“For short-range travel, moving sidewalks (with benches on either side, standing room in the center) will be making their appearance in downtown sections.”

From the Atlantic:

In August of 1964, just more than 50 years ago, author Isaac Asimov wrote a piece in The New York Times, pegged to that summer’s World Fair.

In the essay, Asimov imagines what the World Fair would be like in 2014—his future, our present.

His notions were strange and wonderful (and conservative, as Matt Novak writes in a great run-down), in the way that dreams of the future from the point of view of the American mid-century tend to be. There will be electroluminescent walls for our windowless homes, levitating cars for our transportation, 3D cube televisions that will permit viewers to watch dance performances from all angles, and “Algae Bars” that taste like turkey and steak (“but,” he adds, “there will be considerable psychological resistance to such an innovation”).

He got some things wrong and some things right, as is common for those who engage in the sport of prediction-making. Keeping score is of little interest to me. What is of interest: what Asimov understood about the entangled relationships among humans, technological development, and the planet—and the implications of those ideas for us today, knowing what we know now.

Asimov begins by suggesting that in the coming decades, the gulf between humans and “nature” will expand, driven by technological development. “One thought that occurs to me,” he writes, “is that men will continue to withdraw from nature in order to create an environment that will suit them better. “

It is in this context that Asimov sees the future shining bright: underground, suburban houses, “free from the vicissitudes of weather, with air cleaned and light controlled, should be fairly common.” Windows, he says, “need be no more than an archaic touch,” with programmed, alterable, “scenery.” We will build our own world, an improvement on the natural one we found ourselves in for so long. Separation from nature, Asimov implies, will keep humans safe—safe from the irregularities of the natural world, and the bombs of the human one, a concern he just barely hints at, but that was deeply felt at the time.

But Asimov knows too that humans cannot survive on technology alone. Eight years before astronauts’ Blue Marble image of Earth would reshape how humans thought about the planet, Asimov sees that humans need a healthy Earth, and he worries that an exploding human population (6.5 billion, he accurately extrapolated) will wear down our resources, creating massive inequality.

Although technology will still keep up with population through 2014, it will be only through a supreme effort and with but partial success. Not all the world’s population will enjoy the gadgety world of the future to the full. A larger portion than today will be deprived and although they may be better off, materially, than today, they will be further behind when compared with the advanced portions of the world. They will have moved backward, relatively.

This troubled him, but the real problems lay yet further in the future, as “unchecked” population growth pushed urban sprawl to every corner of the planet, creating a “World-Manhattan” by 2450. But, he exclaimed, “society will collapse long before that!” Humans would have to stop reproducing so quickly to avert this catastrophe, he believed, and he predicted that by 2014 we would have decided that lowering the birth rate was a policy priority.

Asimov rightly saw the central role of the planet’s environmental health to a society: No matter how technologically developed humanity becomes, there is no escaping our fundamental reliance on Earth (at least not until we seriously leave Earth, that is). But in 1964 the environmental specters that haunt us today—climate change and impending mass extinctions—were only just beginning to gain notice. Asimov could not have imagined the particulars of this special blend of planetary destruction we are now brewing—and he was overly optimistic about our propensity to take action to protect an imperiled planet.

A Cry For Attention

Peter-Essick

If Mother Earth could post a handful of selfies to awaken us all to the damage, destruction and devastation wrought by its so-called intelligent inhabitants, these would be the images. Peter Essick, National Geographic photo-essayist, gives our host a helping hand with a stunning collection of photographs in his new book, Our Beautiful, Fragile World; images of sadness and loss.

See more of Essick’s photographs here.

From ars technica:

The first song, The Ballad of Bill Hubbard, on Roger Waters’ album Amused to Death begins with an anecdote. It is the story of a wounded soldier asking to be abandoned to die on the battlefield. Told in a matter-of-fact tone by the aged voice of the soldier who abandoned him, it creates a strong counterpoint to the emotion that underlies the story. It evokes sepia-toned images of pain and loss.

Matter-of-fact story telling makes Peter Essick’s book, Our Beautiful, Fragile World, an emotional snapshot of environmental tragedies in progress. Essick is a photojournalist for National Geographic who has spent the last 25 years documenting man’s devastating impact on the environment. In this respect, Essick has the advantage of Waters in that the visual imagery linked to each story leaves nothing to chance.

Essick has put about a hundred of his most evocative images in a coffee table book. The images range over the world in location. We go from the wilds of Alaska, the Antarctic, and Torres Del Paine National Park in Chile, to the everyday in a Home Depot parking lot in Baltimore and a picnic on the banks of the Patuxent River.

The storytelling complements the imagery very well. Indeed, Essick’s matter-of-fact voice lets the reader draw their emotional response from the photos and their relationship to the story. The strongest are often the most mundane. The tragedy of incomplete and unsuccessful cleanup efforts in Chesapeake Bay is made all the more poignant by the image of recreational users enjoying the bay while adding further damage. This is the second theme of the book: even environmental damage can be made to look stunningly beautiful. The infinity room at Idaho Nuclear Engineering and Environmental Laboratory dazzles the eye, while one can’t help but stare in wonder at the splendid desolation created by mining the Canadian Oil Sands.

Despite the beauty, though, the overriding tone is one of sadness. Sadness for what we have lost, what we are losing, and what will soon be lost. In some sense, these images are about documenting what we have thrown away. This is a sepia-toned book, even though the images are not. I consider myself to be environmentally aware. I have made efforts to reduce my carbon footprint; I don’t own a car; we have reduced the amount of meat in our diet; we read food labels to try to purchase from sustainable sources. Yet, this book makes me realise how much more we have to do, while my own life tells me how hard that actually is.

This book is really a cry for attention. It brings into stark relief the hidden consequences of modern life. Our appetite for energy, for plastics, for food, and for metals is, without doubt, causing huge damage to the Earth. Some of it is local: hard rock mining leaving water not just undrinkable but too acidic to touch and land nearby unusable. Other problems are global: carbon emissions and climate change. Even amidst the evidence of this devastation, Essick remains sympathetic to the people caught in the story; that hard rock mining is done by people who are to be treated with dignity. This aspect of Essick’s approach gives his book a humanity that a simple environmental-warrior story would lack.

In only one place does Essick’s matter-of-fact approach breakdown. The story of climate change is deeply troubling, and he lets his pessimism and anger leak through. Although these feelings are not discussed directly, Essick—and, indeed many of us—are deeply frustrated by the lack of political will. Although the climate vignettes are too short to capture the issues, the failure of our society to act are laid out in plain sight.

The images are, without exception, stunning, and Essick has done about as well as is possible given the format. And, therein lies my only real complaint about the book. I don’t really get on with coffee table books. As you may have guessed from my effusiveness above, I love the photography. The central theme of the book is strong and compelling. The imagery, combined with the vignettes, are individually evocative. But, as with all coffee table books, the individual stories lack a certain… something. A good short story is evocative and complete, while still telling a complex story. The vignettes in coffee table books, however, are more like extended captions. What I want instead is a good short story.

Only Three Feet

Three feet. Three feet is nothing you say. Three feet is less than the difference between the shallow and deep ends of most swimming pools. Well, when the three feet is the mean ocean level rise it becomes a little more significant. And, when that three feet is the rise predicted to happen within the next 87 years, by 2100, it’s, well, how do you say, catastrophic.

A rise like that and you can kiss goodbye to your retirement home in Miami, and for that matter, kiss goodbye to much of southern Florida, and many coastal communities around the world.

From the New York Times:

An international team of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could rise by more than three feet by the end of the century if emissions continue at a runaway pace.

The scientists, whose findings are reported in a summary of the next big United Nations climate report, largely dismiss a recent slowdown in the pace of warming, which is often cited by climate change contrarians, as probably related to short-term factors. The report emphasizes that the basic facts giving rise to global alarm about future climate change are more established than ever, and it reiterates that the consequences of runaway emissions are likely to be profound.

“It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010,” the draft report says. “There is high confidence that this has warmed the ocean, melted snow and ice, raised global mean sea level, and changed some climate extremes in the second half of the 20th century.”

The “extremely likely” language is stronger than in the last major United Nations report, published in 2007, and it means the authors of the draft document are now 95 percent to 100 percent confident that human activity is the primary influence on planetary warming. In the 2007 report, they said they were 90 percent to 100 percent certain on that issue.

On another closely watched issue, however, the authors retreated slightly from their 2007 position.

On the question of how much the planet could warm if carbon dioxide levels in the atmosphere doubled, the previous report had largely ruled out any number below 3.6 degrees Fahrenheit. The new draft says the rise could be as low as 2.7 degrees, essentially restoring a scientific consensus that prevailed from 1979 to 2007.

Most scientists see only an outside chance that the warming will be as low as either of those numbers, with the published evidence suggesting that an increase above 5 degrees Fahrenheit is likely if carbon dioxide doubles.

The new document is not final and will not become so until an intensive, closed-door negotiating session among scientists and government leaders in Stockholm in late September. But if the past is any guide, most of the core findings of the document will survive that final review.

The document was leaked over the weekend after it was sent to a large group of people who had signed up to review it. It was first reported on in detail by the Reuters news agency, and The New York Times obtained a copy independently to verify its contents.

It was prepared by the Intergovernmental Panel on Climate Change, a large, international group of scientists appointed by the United Nations. The group does no original research, but instead periodically assesses and summarizes the published scientific literature on climate change.

“The text is likely to change in response to comments from governments received in recent weeks and will also be considered by governments and scientists at a four-day approval session at the end of September,” the panel’s spokesman, Jonathan Lynn, said in a statement Monday. “It is therefore premature and could be misleading to attempt to draw conclusions from it.”

The intergovernmental panel won the Nobel Peace Prize along with Al Gore in 2007 for seeking to educate the world’s citizens about the risks of global warming. But it has also become a political target for climate contrarians, who helped identify several minor errors in the last big report from 2007. This time, the group adopted rigorous procedures in hopes of preventing such mistakes.

On sea level, one of the biggest single worries about climate change, the new report goes well beyond the one from 2007, which largely sidestepped the question of how much the ocean could rise this century.

The new report lays out several scenarios. In the most optimistic, the world’s governments would prove far more successful at getting emissions under control than they have been in the recent past, helping to limit the total warming.

In that circumstance, sea level could be expected to rise as little as 10 inches by the end of the century, the report found. That is a bit more than the eight-inch rise in the 20th century, which proved manageable even though it caused severe erosion along the world’s shorelines.

Citizens and Satellites: SkyTruth

Daily we are reminded how much our world has changed and how it continues to transform. Technology certainly aids those who seek to profit from Earth’s resources, as they drill, cut, dig, and explode. Some use it wisely, while others leave our fragile home covered in scars of pollution and exploitation — often unseen.

For those who care passionately about the planet, satellite surveillance has become an tool essential tool — in powerful yet unexpected ways.

From the Washington Post:

Somewhere in the South Pacific, thousands of miles from the nearest landfall, there is a fishing ship. Let’s say you’re on it. Go onto the open deck, scream, jump around naked, fire a machine gun into the air — who will ever know? You are about as far from anyone as it is possible to be.

But you know what you should do? You should look up and wave.

Because 438 miles above you, moving at 17,000 miles per hour, a polar-orbiting satellite is taking your photograph. A man named John Amos is looking at you. He knows the name and size of your ship, how fast you’re moving and, perhaps, if you’re dangling a line in the water, what type of fish you’re catching.

Sheesh, you’re thinking, Amos must be some sort of highly placed international official in maritime law. … Nah.

He’s a 50-year-old geologist who heads a tiny nonprofit called SkyTruth in tiny Shepherdstown, W.Va., year-round population, 805.

Amos is looking at these ships to monitor illegal fishing in Chilean waters. He’s doing it from a quiet, shaded street, populated mostly with old houses, where the main noises are (a) birds and (b) the occasional passing car. His office, in a one-story building, shares a toilet with a knitting shop.

With a couple of clicks on the keyboard, Amos switches his view from the South Pacific to Tioga County, Pa., where SkyTruth is cataloguing, with a God’s-eye view, the number and size of fracking operations. Then it’s over to Appalachia for a 40-year history of what mountaintop-removal mining has wrought, all through aerial and satellite imagery, 59 counties covering four states.

“You can track anything in the world from anywhere in the world,” Amos is saying, a smile coming into his voice. “That’s the real revolution.”

Amos is, by many accounts, reshaping the postmodern environmental movement. He is among the first, if not the only, scientist to take the staggering array of satellite data that have accumulated over 40 years, turn it into maps with overlays of radar or aerial flyovers, then fan it out to environmental agencies, conservation nonprofit groups and grass-roots activists. This arms the little guys with the best data they’ve ever had to challenge oil, gas, mining and fishing corporations over how they’re changing the planet.

His satellite analysis of the gulf oil spill in 2010, posted on SkyTruth’s Web site, almost single-handedly forced BP and the U.S. government to acknowledge that the spill was far worse than either was saying.

He was the first to document how many Appalachian mountains have been decapitated in mining operations (about 500) because no state or government organization had ever bothered to find out, and no one else had, either. His work was used in the Environmental Protection Agency’s rare decision to block a major new mine in West Virginia, a decision still working its way through the courts.

“John’s work is absolutely cutting-edge,” says Kert Davies, research director of Greenpeace. “No one else in the nonprofit world is watching the horizon, looking for how to use satellite imagery and innovative new technology.”

“I can’t think of anyone else who’s doing what John is,” says Peter Aengst, regional director for the Wilderness Society’s Northern Rockies office.

Amos’s complex maps “visualize what can’t be seen with the human eye — the big-picture, long-term impact of environment damage,” says Linda Baker, executive director of the Upper Green River Alliance, an activist group in Wyoming that has used his work to illustrate the growth of oil drilling.

This distribution of satellite imagery is part of a vast, unparalleled democratization of humanity’s view of the world, an event not unlike cartography in the age of Magellan, the unknowable globe suddenly brought small.

Sci-Fi Begets Cli-Fi

The world of fiction is populated with hundreds of different genres — most of which were invented by clever marketeers anxious to ensure vampire novels (teen / horror) don’t live next to classic works (literary) on real or imagined (think Amazon) book shelves. So, it should come as no surprise to see a new category recently emerge: cli-fi.

Short for climate fiction, cli-fi novels explore the dangers of environmental degradation and apocalyptic climate change. Not light reading for your summer break at the beach. But, then again, more books in this category may get us to think often and carefully about preserving our beaches — and the rest of the planet — for our kids.

From the Guardian:

A couple of days ago Dan Bloom, a freelance news reporter based in Taiwan, wrote on the Teleread blog that his word had been stolen from him. In 2012 Bloom had “produced and packaged” a novella called Polar City Red, about climate refugees in a post-apocalyptic Alaska in the year 2075. Bloom labelled the book “cli-fi” in the press release and says he coined that term in 2007, cli-fi being short for “climate fiction”, described as a sub-genre of sci-fi. Polar City Red bombed, selling precisely 271 copies, until National Public Radio (NPR) and the Christian Science Monitor picked up on the term cli-fi last month, writing Bloom out of the story. So Bloom has blogged his reply on Teleread, saying he’s simply pleased the term is now out there – it has gone viral since the NPR piece by Scott Simon. It’s not quite as neat as that – in recent months the term has been used increasingly in literary and environmental circles – but there’s no doubt it has broken out more widely. You can search for cli-fi on Amazon, instantly bringing up a plethora of books with titles such as 2042: The Great Cataclysm, or Welcome to the Greenhouse. Twitter has been abuzz.

Whereas 10 or 20 years ago it would have been difficult to identify even a handful of books that fell under this banner, there is now a growing corpus of novels setting out to warn readers of possible environmental nightmares to come. Barbara Kingsolver’s Flight Behaviour, the story of a forest valley filled with an apparent lake of fire, is shortlisted for the 2013 Women’s prize for fiction. Meanwhile, there’s Nathaniel Rich’s Odds Against Tomorrow, set in a future New York, about a mathematician who deals in worst-case scenarios. In Liz Jensen’s 2009 eco-thriller The Rapture, summer temperatures are asphyxiating and Armageddon is near; her most recent book, The Uninvited, features uncanny warnings from a desperate future. Perhaps the most high-profile cli-fi author is Margaret Atwood, whose 2009 The Year of the Flood features survivors of a biological catastrophe also central to her 2003 novel Oryx and Crake, a book Atwood sometimes preferred to call “speculative fiction”.

Engaging with this subject in fiction increases debate about the issue; finely constructed, intricate narratives help us broaden our understanding and explore imagined futures, encouraging us to think about the kind of world we want to live in. This can often seem difficult in our 24?hour news-on-loop society where the consequences of climate change may appear to be everywhere, but intelligent discussion of it often seems to be nowhere. Also, as the crime genre can provide the dirty thrill of, say, reading about a gruesome fictional murder set on a street the reader recognises, the best cli-fi novels allow us to be briefly but intensely frightened: climate chaos is closer, more immediate, hovering over our shoulder like that murderer wielding his knife. Outside of the narrative of a novel the issue can seem fractured, incoherent, even distant. As Gregory Norminton puts it in his introduction to an anthology on the subject, Beacons: Stories for Our Not-So-Distant Future: “Global warming is a predicament, not a story. Narrative only comes in our response to that predicament.” Which is as good an argument as any for engaging with those stories.

All terms are reductive, all labels simplistic – clearly, the likes of Kingsolver, Jensen and Atwood have a much broader canvas than this one issue. And there’s an argument for saying this is simply rebranding: sci-fi writers have been engaging with the climate-change debate for longer than literary novelists – Snow by Adam Roberts comes to mind – and I do wonder whether this is a term designed for squeamish writers and critics who dislike the box labelled “science fiction”. So the term is certainly imperfect, but it’s also valuable. Unlike sci-fi, cli-fi writing comes primarily from a place of warning rather than discovery. There are no spaceships hovering in the sky; no clocks striking 13. On the contrary, many of the horrors described seem oddly familiar.

Self-Assured Destruction (SAD)

The Cold War between the former U.S.S.R and the United States brought us the perfect acronym for the ultimate human “game” of brinkmanship — it was called MAD, for mutually assured destruction.

Now, thanks to ever-evolving technology, increasing military capability, growing environmental exploitation and unceasing human stupidity we have reached an era that we have dubbed SAD, for self-assured destruction. During the MAD period — the thinking was that it would take the combined efforts of the world’s two superpowers to wreak global catastrophe. Now, as a sign of our so-called progress — in the era of SAD — it only takes one major nation to ensure the destruction of the planet. Few would call this progress. Noam Chomsky offers some choice words on our continuing folly.

From TomDispatch:

 

What is the future likely to bring? A reasonable stance might be to try to look at the human species from the outside. So imagine that you’re an extraterrestrial observer who is trying to figure out what’s happening here or, for that matter, imagine you’re an historian 100 years from now – assuming there are any historians 100 years from now, which is not obvious – and you’re looking back at what’s happening today. You’d see something quite remarkable.

For the first time in the history of the human species, we have clearly developed the capacity to destroy ourselves. That’s been true since 1945. It’s now being finally recognized that there are more long-term processes like environmental destruction leading in the same direction, maybe not to total destruction, but at least to the destruction of the capacity for a decent existence.

And there are other dangers like pandemics, which have to do with globalization and interaction. So there are processes underway and institutions right in place, like nuclear weapons systems, which could lead to a serious blow to, or maybe the termination of, an organized existence.

The question is: What are people doing about it? None of this is a secret. It’s all perfectly open. In fact, you have to make an effort not to see it.

There have been a range of reactions. There are those who are trying hard to do something about these threats, and others who are acting to escalate them. If you look at who they are, this future historian or extraterrestrial observer would see something strange indeed. Trying to mitigate or overcome these threats are the least developed societies, the indigenous populations, or the remnants of them, tribal societies and first nations in Canada. They’re not talking about nuclear war but environmental disaster, and they’re really trying to do something about it.

In fact, all over the world – Australia, India, South America – there are battles going on, sometimes wars. In India, it’s a major war over direct environmental destruction, with tribal societies trying to resist resource extraction operations that are extremely harmful locally, but also in their general consequences. In societies where indigenous populations have an influence, many are taking a strong stand. The strongest of any country with regard to global warming is in Bolivia, which has an indigenous majority and constitutional requirements that protect the “rights of nature.”

Ecuador, which also has a large indigenous population, is the only oil exporter I know of where the government is seeking aid to help keep that oil in the ground, instead of producing and exporting it – and the ground is where it ought to be.

Venezuelan President Hugo Chavez, who died recently and was the object of mockery, insult, and hatred throughout the Western world, attended a session of the U.N. General Assembly a few years ago where he elicited all sorts of ridicule for calling George W. Bush a devil. He also gave a speech there that was quite interesting. Of course, Venezuela is a major oil producer. Oil is practically their whole gross domestic product. In that speech, he warned of the dangers of the overuse of fossil fuels and urged producer and consumer countries to get together and try to work out ways to reduce fossil fuel use. That was pretty amazing on the part of an oil producer. You know, he was part Indian, of indigenous background. Unlike the funny things he did, this aspect of his actions at the U.N. was never even reported.

So, at one extreme you have indigenous, tribal societies trying to stem the race to disaster. At the other extreme, the richest, most powerful societies in world history, like the United States and Canada, are racing full-speed ahead to destroy the environment as quickly as possible. Unlike Ecuador, and indigenous societies throughout the world, they want to extract every drop of hydrocarbons from the ground with all possible speed.

Both political parties, President Obama, the media, and the international press seem to be looking forward with great enthusiasm to what they call “a century of energy independence” for the United States. Energy independence is an almost meaningless concept, but put that aside. What they mean is: we’ll have a century in which to maximize the use of fossil fuels and contribute to destroying the world.

And that’s pretty much the case everywhere. Admittedly, when it comes to alternative energy development, Europe is doing something. Meanwhile, the United States, the richest and most powerful country in world history, is the only nation among perhaps 100 relevant ones that doesn’t have a national policy for restricting the use of fossil fuels, that doesn’t even have renewable energy targets. It’s not because the population doesn’t want it. Americans are pretty close to the international norm in their concern about global warming. It’s institutional structures that block change. Business interests don’t want it and they’re overwhelmingly powerful in determining policy, so you get a big gap between opinion and policy on lots of issues, including this one.

So that’s what the future historian – if there is one – would see. He might also read today’s scientific journals. Just about every one you open has a more dire prediction than the last.

The other issue is nuclear war. It’s been known for a long time that if there were to be a first strike by a major power, even with no retaliation, it would probably destroy civilization just because of the nuclear-winter consequences that would follow. You can read about it in the Bulletin of Atomic Scientists. It’s well understood. So the danger has always been a lot worse than we thought it was.

We’ve just passed the 50th anniversary of the Cuban Missile Crisis, which was called “the most dangerous moment in history” by historian Arthur Schlesinger, President John F. Kennedy’s advisor. Which it was. It was a very close call, and not the only time either. In some ways, however, the worst aspect of these grim events is that the lessons haven’t been learned.

What happened in the missile crisis in October 1962 has been prettified to make it look as if acts of courage and thoughtfulness abounded. The truth is that the whole episode was almost insane. There was a point, as the missile crisis was reaching its peak, when Soviet Premier Nikita Khrushchev wrote to Kennedy offering to settle it by a public announcement of a withdrawal of Russian missiles from Cuba and U.S. missiles from Turkey. Actually, Kennedy hadn’t even known that the U.S. had missiles in Turkey at the time. They were being withdrawn anyway, because they were being replaced by more lethal Polaris nuclear submarines, which were invulnerable.

So that was the offer. Kennedy and his advisors considered it – and rejected it. At the time, Kennedy himself was estimating the likelihood of nuclear war at a third to a half. So Kennedy was willing to accept a very high risk of massive destruction in order to establish the principle that we – and only we – have the right to offensive missiles beyond our borders, in fact anywhere we like, no matter what the risk to others – and to ourselves, if matters fall out of control. We have that right, but no one else does.

Kennedy did, however, accept a secret agreement to withdraw the missiles the U.S. was already withdrawing, as long as it was never made public. Khrushchev, in other words, had to openly withdraw the Russian missiles while the US secretly withdrew its obsolete ones; that is, Khrushchev had to be humiliated and Kennedy had to maintain his macho image. He’s greatly praised for this: courage and coolness under threat, and so on. The horror of his decisions is not even mentioned – try to find it on the record.

And to add a little more, a couple of months before the crisis blew up the United States had sent missiles with nuclear warheads to Okinawa. These were aimed at China during a period of great regional tension.

Well, who cares? We have the right to do anything we want anywhere in the world. That was one grim lesson from that era, but there were others to come.

Ten years after that, in 1973, Secretary of State Henry Kissinger called a high-level nuclear alert. It was his way of warning the Russians not to interfere in the ongoing Israel-Arab war and, in particular, not to interfere after he had informed the Israelis that they could violate a ceasefire the U.S. and Russia had just agreed upon. Fortunately, nothing happened.

Ten years later, President Ronald Reagan was in office. Soon after he entered the White House, he and his advisors had the Air Force start penetrating Russian air space to try to elicit information about Russian warning systems, Operation Able Archer. Essentially, these were mock attacks. The Russians were uncertain, some high-level officials fearing that this was a step towards a real first strike. Fortunately, they didn’t react, though it was a close call. And it goes on like that.

At the moment, the nuclear issue is regularly on front pages in the cases of North Korea and Iran. There are ways to deal with these ongoing crises. Maybe they wouldn’t work, but at least you could try. They are, however, not even being considered, not even reported.

MondayMap: The Double Edge of Climate Change

So the changing global climate will imperil our coasts, flood low-lying lands, fuel more droughts, increase weather extremes, and generally make the planet more toasty. But, a new study — for the first time — links increasing levels of CO2 to an increase in global vegetation. Perhaps this portends our eventual fate — ceding the Earth back to the plants — unless humans make some drastic behavioral changes.

From the New Scientist:

The planet is getting lusher, and we are responsible. Carbon dioxide generated by human activity is stimulating photosynthesis and causing a beneficial greening of the Earth’s surface.

For the first time, researchers claim to have shown that the increase in plant cover is due to this “CO2 fertilisation effect” rather than other causes. However, it remains unclear whether the effect can counter any negative consequences of global warming, such as the spread of deserts.

Recent satellite studies have shown that the planet is harbouring more vegetation overall, but pinning down the cause has been difficult. Factors such as higher temperatures, extra rainfall, and an increase in atmospheric CO2 – which helps plants use water more efficiently – could all be boosting vegetation.

To home in on the effect of CO2, Randall Donohue of Australia’s national research institute, the CSIRO in Canberra, monitored vegetation at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is ample warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both.

If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 (Geophysical Research Letters, doi.org/mqx). Donohue says this lends “strong support” to the idea that CO2 fertilisation drove the greening.

Climate change studies have predicted that many dry areas will get drier and that some deserts will expand. Donohue’s findings make this less certain.

However, the greening effect may not apply to the world’s driest regions. Beth Newingham of the University of Idaho, Moscow, recently published the result of a 10-year experiment involving a greenhouse set up in the Mojave desert of Nevada. She found “no sustained increase in biomass” when extra CO2 was pumped into the greenhouse. “You cannot assume that all these deserts respond the same,” she says. “Enough water needs to be present for the plants to respond at all.”

The extra plant growth could have knock-on effects on climate, Donohue says, by increasing rainfall, affecting river flows and changing the likelihood of wildfires. It will also absorb more CO2 from the air, potentially damping down global warming but also limiting the CO2 fertilisation effect itself.

Extreme Weather as the New Norm

Melting glaciers at the poles, wildfires in the western United States, severe flooding across Europe and parts of Asia, hurricanes in northern Australia, warmer temperatures across the globe. According to a many climatologists, including a growing number of ex-climate change skeptics, this is the new normal for our foreseeable future. Welcome to the changed climate.

[div class=attrib]From the New York Times:[end-div]

BY many measurements, this summer’s drought is one for the record books. But so was last year’s drought in the South Central states. And it has been only a decade since an extreme five-year drought hit the American West. Widespread annual droughts, once a rare calamity, have become more frequent and are set to become the “new normal.”

Until recently, many scientists spoke of climate change mainly as a “threat,” sometime in the future. But it is increasingly clear that we already live in the era of human-induced climate change, with a growing frequency of weather and climate extremes like heat waves, droughts, floods and fires.

Future precipitation trends, based on climate model projections for the coming fifth assessment from the Intergovernmental Panel on Climate Change, indicate that droughts of this length and severity will be commonplace through the end of the century unless human-induced carbon emissions are significantly reduced. Indeed, assuming business as usual, each of the next 80 years in the American West is expected to see less rainfall than the average of the five years of the drought that hit the region from 2000 to 2004.

That extreme drought (which we have analyzed in a new study in the journal Nature-Geoscience) had profound consequences for carbon sequestration, agricultural productivity and water resources: plants, for example, took in only half the carbon dioxide they do normally, thanks to a drought-induced drop in photosynthesis.

In the drought’s worst year, Western crop yields were down by 13 percent, with many local cases of complete crop failure. Major river basins showed 5 percent to 50 percent reductions in flow. These reductions persisted up to three years after the drought ended, because the lakes and reservoirs that feed them needed several years of average rainfall to return to predrought levels.

In terms of severity and geographic extent, the 2000-4 drought in the West exceeded such legendary events as the Dust Bowl of the 1930s. While that drought saw intervening years of normal rainfall, the years of the turn-of-the-century drought were consecutive. More seriously still, long-term climate records from tree-ring chronologies show that this drought was the most severe event of its kind in the western United States in the past 800 years. Though there have been many extreme droughts over the last 1,200 years, only three other events have been of similar magnitude, all during periods of “megadroughts.”

Most frightening is that this extreme event could become the new normal: climate models point to a warmer planet, largely because of greenhouse gas emissions. Planetary warming, in turn, is expected to create drier conditions across western North America, because of the way global-wind and atmospheric-pressure patterns shift in response.

Indeed, scientists see signs of the relationship between warming and drought in western North America by analyzing trends over the last 100 years; evidence suggests that the more frequent drought and low precipitation events observed for the West during the 20th century are associated with increasing temperatures across the Northern Hemisphere.

These climate-model projections suggest that what we consider today to be an episode of severe drought might even be classified as a period of abnormal wetness by the end of the century and that a coming megadrought — a prolonged, multidecade period of significantly below-average precipitation — is possible and likely in the American West.

Two Degrees

Author and environmentalist Bill McKibben has been writing about climate change and environmental issues for over 20 years. His first book, The End of Nature, was published in 1989, and is considered to be the first book aimed at the general public on the subject of climate change.

In his latest essay in Rolling Stone, which we excerpt below, McKibben offers a sobering assessment based on our current lack of action on a global scale. He argues that in the face of governmental torpor, and with individual action being almost inconsequential (at this late stage), only a radical re-invention of our fossil-fuel industries — to energy companies in the broad sense — can bring significant and lasting change.

Learn more about Bill McKibben, here.

[div class=attrib]From Rolling Stone:[end-div]

If the pictures of those towering wildfires in Colorado haven’t convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe.

Meteorologists reported that this spring was the warmest ever recorded for our nation – in fact, it crushed the old record by so much that it represented the “largest temperature departure from average of any season on record.” The same week, Saudi authorities reported that it had rained in Mecca despite a temperature of 109 degrees, the hottest downpour in the planet’s history.

Not that our leaders seemed to notice. Last month the world’s nations, meeting in Rio for the 20th-anniversary reprise of a massive 1992 environmental summit, accomplished nothing. Unlike George H.W. Bush, who flew in for the first conclave, Barack Obama didn’t even attend. It was “a ghost of the glad, confident meeting 20 years ago,” the British journalist George Monbiot wrote; no one paid it much attention, footsteps echoing through the halls “once thronged by multitudes.” Since I wrote one of the first books for a general audience about global warming way back in 1989, and since I’ve spent the intervening decades working ineffectively to slow that warming, I can say with some confidence that we’re losing the fight, badly and quickly – losing it because, most of all, we remain in denial about the peril that human civilization is in.

When we think about global warming at all, the arguments tend to be ideological, theological and economic. But to grasp the seriousness of our predicament, you just need to do a little math. For the past year, an easy and powerful bit of arithmetical analysis first published by financial analysts in the U.K. has been making the rounds of environmental conferences and journals, but it hasn’t yet broken through to the larger public. This analysis upends most of the conventional political thinking about climate change. And it allows us to understand our precarious – our almost-but-not-quite-finally hopeless – position with three simple numbers.

The First Number: 2° Celsius

If the movie had ended in Hollywood fashion, the Copenhagen climate conference in 2009 would have marked the culmination of the global fight to slow a changing climate. The world’s nations had gathered in the December gloom of the Danish capital for what a leading climate economist, Sir Nicholas Stern of Britain, called the “most important gathering since the Second World War, given what is at stake.” As Danish energy minister Connie Hedegaard, who presided over the conference, declared at the time: “This is our chance. If we miss it, it could take years before we get a new and better one. If ever.”

In the event, of course, we missed it. Copenhagen failed spectacularly. Neither China nor the United States, which between them are responsible for 40 percent of global carbon emissions, was prepared to offer dramatic concessions, and so the conference drifted aimlessly for two weeks until world leaders jetted in for the final day. Amid considerable chaos, President Obama took the lead in drafting a face-saving “Copenhagen Accord” that fooled very few. Its purely voluntary agreements committed no one to anything, and even if countries signaled their intentions to cut carbon emissions, there was no enforcement mechanism. “Copenhagen is a crime scene tonight,” an angry Greenpeace official declared, “with the guilty men and women fleeing to the airport.” Headline writers were equally brutal: COPENHAGEN: THE MUNICH OF OUR TIMES? asked one.

The accord did contain one important number, however. In Paragraph 1, it formally recognized “the scientific view that the increase in global temperature should be below two degrees Celsius.” And in the very next paragraph, it declared that “we agree that deep cuts in global emissions are required… so as to hold the increase in global temperature below two degrees Celsius.” By insisting on two degrees – about 3.6 degrees Fahrenheit – the accord ratified positions taken earlier in 2009 by the G8, and the so-called Major Economies Forum. It was as conventional as conventional wisdom gets. The number first gained prominence, in fact, at a 1995 climate conference chaired by Angela Merkel, then the German minister of the environment and now the center-right chancellor of the nation.

Some context: So far, we’ve raised the average temperature of the planet just under 0.8 degrees Celsius, and that has caused far more damage than most scientists expected. (A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.) Given those impacts, in fact, many scientists have come to think that two degrees is far too lenient a target. “Any number much above one degree involves a gamble,” writes Kerry Emanuel of MIT, a leading authority on hurricanes, “and the odds become less and less favorable as the temperature goes up.” Thomas Lovejoy, once the World Bank’s chief biodiversity adviser, puts it like this: “If we’re seeing what we’re seeing today at 0.8 degrees Celsius, two degrees is simply too much.” NASA scientist James Hansen, the planet’s most prominent climatologist, is even blunter: “The target that has been talked about in international negotiations for two degrees of warming is actually a prescription for long-term disaster.” At the Copenhagen summit, a spokesman for small island nations warned that many would not survive a two-degree rise: “Some countries will flat-out disappear.” When delegates from developing nations were warned that two degrees would represent a “suicide pact” for drought-stricken Africa, many of them started chanting, “One degree, one Africa.”

Despite such well-founded misgivings, political realism bested scientific data, and the world settled on the two-degree target – indeed, it’s fair to say that it’s the only thing about climate change the world has settled on. All told, 167 countries responsible for more than 87 percent of the world’s carbon emissions have signed on to the Copenhagen Accord, endorsing the two-degree target. Only a few dozen countries have rejected it, including Kuwait, Nicaragua and Venezuela. Even the United Arab Emirates, which makes most of its money exporting oil and gas, signed on. The official position of planet Earth at the moment is that we can’t raise the temperature more than two degrees Celsius – it’s become the bottomest of bottom lines. Two degrees.

The Plastic Bag Wars

[div class=attrib]From Rolling Stone:[end-div]

American shoppers use an estimated 102 billion plastic shopping bags each year — more than 500 per consumer. Named by Guinness World Records as “the most ubiquitous consumer item in the world,” the ultrathin bags have become a leading source of pollution worldwide. They litter the world’s beaches, clog city sewers, contribute to floods in developing countries and fuel a massive flow of plastic waste that is killing wildlife from sea turtles to camels. “The plastic bag has come to represent the collective sins of the age of plastic,” says Susan Freinkel, author of Plastic: A Toxic Love Story.

Many countries have instituted tough new rules to curb the use of plastic bags. Some, like China, have issued outright bans. Others, including many European nations, have imposed stiff fees to pay for the mess created by all the plastic trash. “There is simply zero justification for manufacturing them anymore, anywhere,” the United Nations Environment Programme recently declared. But in the United States, the plastics industry has launched a concerted campaign to derail and defeat anti-bag measures nationwide. The effort includes well-placed political donations, intensive lobbying at both the state and national levels, and a pervasive PR campaign designed to shift the focus away from plastic bags to the supposed threat of canvas and paper bags — including misleading claims that reusable bags “could” contain bacteria and unsafe levels of lead.

“It’s just like Big Tobacco,” says Amy Westervelt, founding editor of Plastic Free Times, a website sponsored by the nonprofit Plastic Pollution Coalition. “They’re using the same underhanded tactics — and even using the same lobbying firm that Philip Morris started and bankrolled in the Nineties. Their sole aim is to maintain the status quo and protect their profits. They will stop at nothing to suppress or discredit science that clearly links chemicals in plastic to negative impacts on human, animal and environmental health.”

Made from high-density polyethylene — a byproduct of oil and natural gas — the single-use shopping bag was invented by a Swedish company in the mid-Sixties and brought to the U.S. by ExxonMobil. Introduced to grocery-store checkout lines in 1976, the “T-shirt bag,” as it is known in the industry, can now be found literally every where on the planet, from the bottom of the ocean to the peaks of Mount Everest. The bags are durable, waterproof, cheaper to produce than paper bags and able to carry 1,000 times their own weight. They are also a nightmare to recycle: The flimsy bags, many thinner than a strand of human hair, gum up the sorting equipment used by most recycling facilities. “Plastic bags and other thin-film plastic is the number-one enemy of the equipment we use,” says Jeff Murray, vice president of Far West Fibers, the largest recycler in Oregon. “More than 300,000 plastic bags are removed from our machines every day — and since most of the removal has to be done by hand, that means more than 25 percent of our labor costs involves plastic-bag removal.”

The Strange Forests that Drink—and Eat—Fog

[div class=attrib]From Discover:[end-div]

On the rugged roadway approaching Fray Jorge National Park in north-central Chile, you are surrounded by desert. This area receives less than six inches of rain a year, and the dry terrain is more suggestive of the badlands of the American Southwest than of the lush landscapes of the Amazon. Yet as the road climbs, there is an improbable shift. Perched atop the coastal mountains here, some 1,500 to 2,000 feet above the level of the nearby Pacific Ocean, are patches of vibrant rain forest covering up to 30 acres apiece. Trees stretch as much as 100 feet into the sky, with ferns, mosses, and bromeliads adorning their canopies. Then comes a second twist: As you leave your car and follow a rising path from the shrub into the forest, it suddenly starts to rain. This is not rain from clouds in the sky above, but fog dripping from the tree canopy. These trees are so efficient at snatching moisture out of the air that the fog provides them with three-quarters of all the water they need.

Understanding these pocket rain forests and how they sustain themselves in the middle of a rugged desert has become the life’s work of a small cadre of scientists who are only now beginning to fully appreciate Fray Jorge’s third and deepest surprise: The trees that grow here do more than just drink the fog. They eat it too.

Fray Jorge lies at the north end of a vast rain forest belt that stretches southward some 600 miles to the tip of Chile. In the more southerly regions of this zone, the forest is wetter, thicker, and more contiguous, but it still depends on fog to survive dry summer conditions. Kathleen C. Weathers, an ecosystem scientist at the Cary Institute of Ecosystem Studies in Millbrook, New York, has been studying the effects of fog on forest ecosystems for 25 years, and she still cannot quite believe how it works. “One step inside a fog forest and it’s clear that you’ve entered a remarkable ecosystem,” she says. “The ways in which trees, leaves, mosses, and bromeliads have adapted to harvest tiny droplets of water that hang in the atmosphere is unparalleled.”
