Arctic sea ice fell to record low for May

The Guardian - Thu, 2016-06-09 00:42

This year could be worst ever for melt as data shows average sea ice extent for last month was more than half a million square kilometres smaller than the previous record of May 2012

Arctic sea ice fell to its lowest ever May extent, prompting fears that this year could beat 2012 for the record of worst ever summer sea ice melt.

Data published by the US National Snow and Ice Data Centre (NSIDC) this week showed average sea ice extent for last month was more than 500,000 sq km (193,000 sq miles) smaller than May 2012.

How Bernie Sanders made Hillary Clinton into a greener candidate

The Guardian - Thu, 2016-06-09 00:10

He may have lost his campaign, but Sanders achieved major wins, making his rival promise more on green policies and climate change, reports Grist

Hillary Clinton is her party’s presumptive nominee. Whether Sanders drops out tomorrow or the day he loses the roll-call vote at the Democratic convention in Philadelphia, his campaign is over.

But if ever there were a losing campaign that achieved some major wins, it’s Sanders’. Not only did he force Clinton to talk more about economic inequality, he pushed her to promise stronger action to fight climate change and rein in fossil fuel companies. If Hillary Clinton becomes president and keeps some of her more recent promises to restrict oil drilling and fracking, Sanders will deserve a share of the credit.

To protect oceans from microplastics the UK must work with Europe | Mary Creagh

The Guardian - Wed, 2016-06-08 20:15

The microbead pollution contaminating our marine life does not respect borders. As UK ministers meet on World Oceans Day they must look to find solutions by working with our neighbours and partners in Europe

From the shallowest coastal waters to the depths of the oceanic trenches some 10,000 meters beneath the sea, our oceans are home to a vast amount of life on earth. Covering over two-thirds of the world’s surface, they provide food and support tourism and leisure in every part of the world.

Our oceans are under pressure from warming and acidification, and on World Oceans Day, the environmental audit committee, which I chair, will be hearing about microplastic pollution.

Trump and global warming: Americans are failing risk management | Dana Nuccitelli

The Guardian - Wed, 2016-06-08 20:00

40% of Americans don’t understand the risks posed by climate change or a President Donald Trump

Currently, about 40% of Americans support Donald Trump in the 2016 presidential election, and about 40% of Americans are not worried about global warming. While short of a majority, this is a substantial fraction of the American public failing to grasp the risks associated with a Donald Trump presidency and potentially catastrophic climate change impacts.

In Business Insider, Josh Barro recently wrote about the former:

Down to 60: scientists mull risky captive breeding for panda porpoise

The Guardian - Wed, 2016-06-08 18:07

As the vaquita – the world’s smallest porpoise – plunges toward extinction, scientists have a tough decision ahead of them: to attempt a super risky captive breeding programme or not?

Today, there are approximately 7.3 billion people on the planet – and only 60 vaquitas. The vaquita has seen its population drop by 92 percent in less than 20 years in Mexico’s Gulf of California as the tiny porpoises suffocate to death one-by-one in gillnets. Now, scientists with the International Committee for the Recovery of the Vaquita (CIRVA) are cautiously moving forward on a once unthinkable option: captive breeding.

“We have no idea whether it is feasible to find, capture and maintain vaquitas in captivity much less whether they will reproduce,” said Barbara Taylor, one of the world’s foremost experts on the vaquita with NOAA. “The uncertainties are large.”

How do we weigh the moral value of human lives against animal ones?

The Conversation - Wed, 2016-06-08 16:59

Imagine a unique set of scales that measures the value of life. If a single human were on one side, how many chimpanzees (our closest genetic relatives) would need to be on the other side before the scales tipped in their direction?

This may seem like an abstract, irrelevant or even offensive question to some people. But it was made horrifically real by the death last week of Harambe, the Cincinnati Zoo gorilla who was shot after a young boy fell into his enclosure.

Zoo handlers were faced with the agonising decision to take Harambe’s life to ensure the young boy would not lose his. The response to this event online has varied from anger, to sadness, through to considerations of how much choice the zoo’s staff really had. How do we decide what our own lives are worth compared with other species?

Perhaps we can try to frame the comparison in relative terms. There are 7.4 billion human beings on the planet, whereas Western lowland gorillas are critically endangered. Does a human life hold more value than that of a member of a critically endangered animal species?

Harambe’s death suggests that the instinctive answer is yes, but is there a point at which some people’s moral scales might tip the other way? Our research suggests there might be.

The concept of ‘moral expansion’

No one expects an easy answer to this question. But the fact that we can even ask it shows that our moral sensibilities have expanded beyond the boundaries of our own species.

Many of us feel a deep moral responsibility not just to protect our fellow humans, but to guard the moral rights of entities the world over. This change, which has spanned the past few centuries, has resulted in some serious ethical challenges to the ways we interact with other species and the environment.

Recently, animal rights organisations in the United States have fought for the legal personhood status of chimpanzees like Tommy, while animal advocates have petitioned the United Nations for a Declaration of the Rights of Great Apes since 1993.

In the meantime, a river in New Zealand has been officially granted legal personhood status (similar to the status given to corporations), making the river a legal “person” with its own rights and interests under law.

In line with the concept of compassionate conservation, these examples highlight the narrowing of the gulf between the moral rights of humans, non-humans and the environment.

For supporters of these causes, human rights and corresponding moral standing should no longer be restricted to humans.

Are you willing to sacrifice?

The legal semantics are interesting, but what about when it really comes to the crunch? Our recent research has examined how widely people spread their moral concern to others. We found that this is a key predictor of the type of moral decision-making that compares the value of a human life to that of another animal.

We asked people the following question: how many other human beings would need to be in danger before you sacrificed your own life to ensure their survival? But our research didn’t stop at humans.

We also asked how many chimpanzees would need to be at risk. How many ants? How many redwood trees?

Responses to these questions were as varied as the responses to the shooting of Harambe.

Some people said they would sacrifice their life if it meant that just a few chimpanzees would keep theirs. Others said it wouldn’t matter how many animals or trees were in danger; a human life was simply worth more.

We found that we could predict people’s responses to specific questions based on their position on what we call the “moral expansiveness scale” (you can find out your own score here). Those whose moral outlook stretched further beyond humans were more likely to say they would sacrifice themselves to benefit other animals or nature.

A moral dilemma

Human beings are becoming increasingly morally expansive. As a species we are adopting a moral standard that represents ethical and altruistic responsibilities on a global scale. This is reflected in the extension of human rights to chimpanzees and the granting of legal rights to elements of our natural environment.

However, this trend is accompanied by an escalating moral conflict. The extension of our moral boundaries is happening just as the global human population is growing exponentially, leading to tension and competition over scarce resources.

As a consequence, we are increasingly likely to face ethical dilemmas over the value of human versus non-human life. It won’t be in the form of a quick decision to kill an animal to save the life of a child. These dilemmas will play out in courtrooms and parliaments, as human needs are pitted against environmental ones, and as the battle for natural resources brings threats of deforestation and species extinction.

As we edge ever closer to the brink of the Earth’s sixth mass extinction, perhaps we need to consider just exactly what a human life is worth.

Complete our survey to find out how morally expansive you are.

A bird in the house disturbs the order of things

Wenlock Edge The blackbird’s wings have the flutter of panic as he tries to navigate through the house to find an escape

The unmistakable fan-snap of feathers announces the arrival of a visitor. A dark blur up the stairs, a spike of electric current. There is a palpable disturbance to the order of things when there’s a bird in the house; perhaps that’s why it’s associated with ill omen. The blackbird hops through the back door following a trail of breakfast cereal.

We have become familiar to each other. We share the same space in the backyard where he forages, and we leave crumbs and titbits. It could be that he was born in the garden and has known us all his life, as did his parents. Now he has a nest and a brood of chicks to feed, we listen to him sing; we live in parallel and have retreated to our separate worlds, until now.

Taking the city’s pulse: we need to link urban vitality back to the planet

The Conversation - Wed, 2016-06-08 13:59
Much of the 'smart cities' rhetoric is dominated by the economic, with little reference to the natural world and its plight. Ase from www.shutterstock.com

Back in the 1960s, the influential urban planner and journalist Jane Jacobs put American cities under the microscope. Jacobs was aiming to explain, and suggest ways of remedying, the hollowing out, or “doughnut effect”, which left previously well-functioning city centres rundown and devoid of new blood.

The effect was less dramatic in Australian cities, which had few, if any, residential populations in their central business districts until comparatively recently. And many of the innermost suburbs that surrounded the CBDs were industrialised and yet to feel the decline of manufacturing.

Of course, today the situation is completely reversed across Western cities. The emergence of the service economy and explosive growth of professional classes are promoting gentrification and squillion-dollar property values.

Jacobs’ conditions for a vibrant city life were that districts must serve at least two functions to attract persons of different purposes around the clock. Further, blocks must be small, with many opportunities for pedestrians to interact and a diverse range of buildings. Finally, there needed to be reasonable density. The idea was that “vitality” had a lot to do with chance encounters.

Digital entanglement Digital interconnectivity is increasingly taken to be a measure of a city’s vitality. Ekaphon Maneechot from www.shutterstock.com

Jacobs’ encounters have now been supplemented if not entirely supplanted by social media. Enter some Italian researchers who hit upon the idea of mining “big data”. In this case, they used mobile phone calls cross-referenced to satellite-derived records such as Open Street Map to gauge where precisely this feverish activity was happening across six of Italy’s large cities. (In corroboration of Jacobs’ thesis, the best places were found to be “day end points” with concentrations of office workers at large, as well as small streets and blocks with historic buildings.)

There’s a sense that this “interconnectivity” is becoming a signal of city vitality/vibrancy. The two elements are becoming entangled like subatomic particles.

Moreover, it’s a natural fit with the vogue for blending IT with strategic planning. The new ministerial portfolio, cities and digital transformation, exemplifies this.

Smart city buzz

You don’t have to venture far into urban policy space before coming across the idea of the “smart city”. There’s a near-continuous run of conferences on the topic and even a Turnbull government plan. The plan features, among other measures, a blend of big-data thinking, with “better benchmarking of city performance”, and the prescriptions set out in Edward Glaeser’s 2013 book, Triumph of the City.

Glaeser views cities as places where human ingenuity can flourish and skills are developed and refined – a combination driving economic and technological advance. He believes increased densification, including a “vertical city” with yet higher stacks of buildings, is integral to achieving these objectives.

Glaeser, however, illustrates complexities in this debate. Jacobs opposed the view that high-rise cities create beneficial interactions. And concern is growing that increased reliance on digital communication will radically reduce urban human interaction.

Reckoning with a cantankerous planet High-rise cities face particular problems in a warming world. zhangyang13576997233 from www.shutterstock.com

Smart cities need to be “resilient” if they’re to counter, for example, Paul Gilding’s “great disruption”. This includes life-threatening heat, desiccation and killer peri-urban fires. High-rise cities may prove to be the least adaptable human constructions in an era of fundamental change and add considerably to the urban heat island effect

Should an economic perspective – like this, for instance – remain the main if not the sole focus for cities? This in a year when atmospheric carbon reached an irreversible 400ppm; the Great Barrier Reef’s coral is bleaching; wildfires have destroyed towns and cities in Canada; India has recorded its hottest day on record 51°C; Paris has been heavily flooded; and sea-level rise threatens to inundate Silicon Valley, the spiritual home of start-ups – not to mention our home-grown variety of storm surge, erosion and flooding.

Is there something we’re missing? In the rhetoric surrounding smart cities it’s difficult to unearth specific reference to the natural world and its current plight. And when there is, it’s often a few throwaway lines about the value of green space in protecting biological diversity and threatened species.

Contrast this with the growing awareness of the benefits to our psyche of exposure to the natural world (even acting as a boost to productivity in the workplace).

Set these observations against the revelation that today’s children – the inheritors of the smart city – are spending less time outdoors than prisoners. This has occurred in a generation for whom the environment is unlikely to be mainstream given that their reality is ultimately what appears on a screen. Digital connectivity in low-amenity vertical communities is likely to prove a poor substitute for the kind of city Jacobs advocated.

Reconnecting kids and others requires rejigging our perspective, as well as starting to look out for vestiges of wildlife that has sought refuge in our cities. And providing for local food production is as big as big data itself, but that’s something for another day.
