The Guardian reports: When Boston public schools introduced a new standard map of the world this week, some young students’ felt their jaws drop. In an instant, their view of the world had changed.
The USA was small. Europe too had suddenly shrunk. Africa and South America appeared narrower but also much larger than usual. And what had happened to Alaska?
In an age of “fake news” and “alternative facts”, city authorities are confident their new map offers something closer to the geographical truth than that of traditional school maps, and hope it can serve an example to schools across the nation and even the world.
For almost 500 years, the Mercator projection has been the norm for maps of the world, ubiquitous in atlases, pinned on peeling school walls.
Gerardus Mercator, a renowned Flemish cartographer, devised his map in 1569, principally to aid navigation along colonial trade routes by drawing straight lines across the oceans. An exaggeration of the whole northern hemisphere, his depiction made North America and Europe bigger than South America and Africa. He also placed western Europe in the middle of his map.
Mercator’s distortions affect continents as well as nations. For example, South America is made to look about the same size as Europe, when in fact it is almost twice as large, and Greenland looks roughly the size of Africa when it is actually about 14 times smaller. Alaska looks bigger than Mexico and Germany is in the middle of the picture, not to the north – because Mercator moved the equator.
Three days ago, Boston’s public schools began phasing in the lesser-known Peters projection, which cuts the US, Britain and the rest of Europe down to size. Teachers put contrasting maps of the world side by side and let the students study them. [Continue reading…]
Shannon Stirone writes: We glimpsed Earth’s curvature in 1946, via a repurposed German V-2 rocket that flew 65 miles above the surface. Year-by-year, we climbed a little higher, engineering a means to comprehend the magnitude of our home.
In 1968, Apollo 8 lunar module pilot William Anders captured the iconic Earthrise photo. We contemplated the beauty of our home.
But on Valentine’s Day 27 years ago, Voyager 1, from 4 billion miles away, took one final picture before switching off its camera forever. In the image, Earth, Carl Sagan said, was merely “a mote of dust suspended in a sunbeam.” So we pondered the insignificance of our home. The image inspired Sagan to write his book “The Pale Blue Dot,” and it continues to cripple human grandiosity. [Continue reading…]
The Observer reports: One in five species on Earth now faces extinction, and that will rise to 50% by the end of the century unless urgent action is taken. That is the stark view of the world’s leading biologists, ecologists and economists who will gather on Monday to determine the social and economic changes needed to save the planet’s biosphere.
“The living fabric of the world is slipping through our fingers without our showing much sign of caring,” say the organisers of the Biological Extinction conference held at the Vatican this week.
Threatened creatures such as the tiger or rhino may make occasional headlines, but little attention is paid to the eradication of most other life forms, they argue. But as the conference will hear, these animals and plants provide us with our food and medicine. They purify our water and air while also absorbing carbon emissions from our cars and factories, regenerating soil, and providing us with aesthetic inspiration.
“Rich western countries are now siphoning up the planet’s resources and destroying its ecosystems at an unprecedented rate,” said biologist Paul Ehrlich, of Stanford University in California. “We want to build highways across the Serengeti to get more rare earth minerals for our cellphones. We grab all the fish from the sea, wreck the coral reefs and put carbon dioxide into the atmosphere. We have triggered a major extinction event. The question is: how do we stop it?” [Continue reading…]
Nicholas Kristof writes: There’s a broad consensus that the world is falling apart, with every headline reminding us that life is getting worse.
Except that it isn’t. In fact, by some important metrics, 2016 was the best year in the history of humanity. And 2017 will probably be better still.
How can this be? I’m as appalled as anyone by the election of Donald Trump, the bloodshed in Syria, and so on. But while I fear what Trump will do to America and the world, and I applaud those standing up to him, the Trump administration isn’t the most important thing going on. Here, take my quiz:
On any given day, the number of people worldwide living in extreme poverty:
A.) Rises by 5,000, because of climate change, food shortages and endemic corruption.
B.) Stays about the same.
C.) Drops by 250,000.
Polls show that about 9 out of 10 Americans believe that global poverty has worsened or stayed the same. But in fact, the correct answer is C. Every day, an average of about a quarter-million people worldwide graduate from extreme poverty, according to World Bank figures. [Continue reading…]
Nathaniel Scharping writes: Ever since our ancestors cut rough paths through the wilderness, humanity has been laying down trails. From footpaths to highways, a global network of roads binds communities and facilitates the exchange of goods and ideas. But there is a flip side to this creeping tangle of pathways: The roads that bring us closer also serve divide ecosystems into smaller parcels, turning vast expanses into a jigsaw of human mobility.
In a study published in Science, an international team of researchers attempted to quantify the extent to which roads have sliced up the globe. They used data from OpenStreetMap, a crowd-sourced mapping project, to chart how much land is covered by roads. For the purposes of their project, they defined a roadway as everything within a kilometer of the physical road itself (studies have shown measurable impacts on the environment extending out at least that far).
They estimated that roughly 20 percent of land is occupied by roads, not including Greenland and Antarctica. Although that leaves 80 percent as open space, this land is far from whole. Transected by highways and streets, the road-free areas are cut up into some 600,000 individual parcels. Half of these are less than a square mile, while only 7 percent span more than 60 square miles. The true impact of roads seems to be the gradual tessellation of once-cohesive landscapes.

The New York Times reports: At times it was hard to know who was on trial, the smuggler or the state.
The defendant, Cédric Herrou, 37, a slightly built olive farmer, did not deny that for months he had illegally spirited dozens of migrants through the remote mountain valley where he lives. He would do it again, he suggested.
Instead, when asked by a judge, “Why do you do all this?” Mr. Herrou turned the tables and questioned the humanity of France’s practice of rounding up and turning back Africans entering illegally from Italy in search of work and a better life. It was “ignoble,” he said.
“There are people dying on the side of the road,” Mr. Herrou replied. “It’s not right. There are children who are not safe. It is enraging to see children, at 2 in the morning, completely dehydrated.
“I am a Frenchman,” Mr. Herrou declared.
The trial, which began on Wednesday, is no ordinary one. It has been substantially covered by the French news media for its rich symbolism and for the way it neatly sums up the ambiguity of France’s policy toward the unceasing flow of migrants into Europe and the quandary they present.
France, foremost among European nations, prides itself on enlightened humanitarianism, fraternity and solidarity. And yet, perhaps first among them, too, it is struggling to reconcile those values with the pressing realities of a smaller, more globalized world, including fear of terrorism.
The contradictions are being played out in courtrooms, in politics and in farmers’ fields, on the sidewalks of Paris and in train stations from the Côte d’Azur to the northern port of Calais, where the government demolished a giant migrant camp in the fall.
On the one hand, politicians in this year’s presidential election are competing to see who can take the toughest line on securing France’s borders. Most are promising a crackdown on migrants, with admission reserved for clear-cut cases of political persecution. Terrorist attacks, including the one last summer in Nice that killed 85 people, have exacerbated anti-migrant sentiment.
But in these remote mountain valleys, where Jews fleeing the Nazis and the Vichy collaborators found refuge during World War II, Mr. Herrou has become something of a folk hero by leading a kind of loosely knit underground railroad to smuggle migrants north, many destined for Britain or Germany. His work has won him admiration for his resistance to the state and his stand that it is simply right to help one’s fellow man, woman or child. [Continue reading…]
In his Christmas message to the City of Rome and to the world, Pope Francis says: Today this message goes out to the ends of the earth to reach all peoples, especially those scarred by war and harsh conflicts that seem stronger than the yearning for peace.
Peace to men and women in the war-torn land of Syria, where far too much blood has been spilled. Above all in the city of Aleppo, site of the most awful battles in recent weeks, it is most urgent that assistance and support be guaranteed to the exhausted civil populace, with respect for humanitarian law. It is time for weapons to be still forever, and the international community to actively seek a negotiated solution, so that civil coexistence can be restored in the country.
Peace to women and men of the beloved Holy Land, the land chosen and favoured by God. May Israelis and Palestinians have the courage and the determination to write a new page of history, where hate and revenge give way to the will to build together a future of mutual understanding and harmony. May Iraq, Libya and Yemen – where their peoples suffer war and the brutality of terrorism – be able once again to find unity and concord.
Peace to the men and women in various parts of Africa, especially in Nigeria, where fundamentalist terrorism exploits even children in order to perpetrate horror and death. Peace in South Sudan and the Democratic Republic of the Congo, so that divisions may be healed and all people of good will may strive to undertake the path of development and sharing, preferring the culture of dialogue to the mindset of conflict.
Peace to women and men who to this day suffer the consequences of the conflict in Eastern Ukraine, where there is urgent need for a common desire to bring relief to the civil population and to put into practice the commitments which have been assumed.
We implore harmony for the dear people of Colombia, which seeks to embark on a new and courageous path of dialogue and reconciliation. May such courage also motivate the beloved country of Venezuela to undertake the necessary steps to put an end to current tensions, and build together a future of hope for the whole population.
Peace to all who, in different areas, are enduring sufferings due to constant dangers and persistent injustice. May Myanmar consolidate its efforts to promote peaceful coexistence and, with the assistance of the international community, provide necessary protection and humanitarian assistance to all those who gravely and urgently need it. May the Korean peninsula see the tensions it is experiencing overcome in a renewed spirit of cooperation.
Peace to those who have lost a person dear to them as a result of brutal acts of terrorism, and to those who have sown fear and death into the hearts of so many countries and cities.
Peace – not merely the word, but a real and concrete peace – to our abandoned and excluded brothers and sisters, to those who suffer hunger and to all the victims of violence. Peace to exiles, migrants and refugees, to all those who in our day are subject to human trafficking. Peace to the peoples who suffer because of the economic ambitions of the few, because of the sheer greed and the idolatry of money, which leads to slavery. Peace to those affected by social and economic unrest, and to those who endure the consequences of earthquakes or other natural catastrophes.
Peace to the children, on this special day on which God became a child, above all those deprived of the joys of childhood because of hunger, wars or the selfishness of adults.
Peace on earth to men and women of goodwill, who work quietly and patiently each day, in their families and in society, to build a more humane and just world, sustained by the conviction that only with peace is there the possibility of a more prosperous future for all. [Continue reading…]
David Grinspoon writes: As a planetary astrobiologist, I am focused on the major transitions in planetary evolution and the evolving relationship between planets and life. The scientific community is converging on the idea that we have entered a new epoch of Earth history, one in which the net activity of humans has become an agent of global change as powerful as the great forces of nature that shape continents and propel the evolution of species. This concept has garnered a lot of attention, and justly so. Thinking about the new epoch – often called the Anthropocene, or the age of humanity – challenges us to look at ourselves in the mirror of deep time, measured not in centuries or even in millennia, but over millions and billions of years. And yet much of the recent discussion and debate over the Anthropocene still does not come to terms with its full meaning and importance.
Various markers have been proposed for the starting date of the Anthropocene, such as the rise in CO2, isotopes from nuclear tests, the ‘Columbian exchange’ of species between hemispheres when Europeans colonised the Americas, or more ancient human modifications of the landscape or climate. The question in play here is: when did our world gain a quality that is uniquely human? Many species have had a major influence on the globe, but they don’t each get their own planetary transition in the geologic timescale. When did humans begin changing things in a way that no other species has ever changed Earth before? Making massive changes in landscapes is not unique to us. Beavers do plenty of that, for example, when they build dams, alter streams, cut down forests and create new meadows. Even changing global climate and initiating mass extinction is not a human first. Photosynthetic bacteria did that some 2.5 billion years ago.
What distinguishes humans from other world-changing organisms must be related to our great cleverness and adaptability; the power that comes from communicating, planning and working in social groups; transmitting knowledge from one generation to the next; and applying these skills toward altering our surroundings and expanding our habitable domains. However, people have been engaged in these activities for tens of thousands of years, and have produced many different environmental modifications proposed as markers of the Anthropocene’s beginning. Therefore, those definitions strike me as incomplete. Until now, the people causing the disturbances had no way of recognising or even conceiving of a global change. Yes, humans have been altering our planet for millennia, but there is something going on now that was not happening when we started doing all that world-changing. [Continue reading…]
The Guardian reports: The Prince of Wales has warned that the rise of populist extremism and intolerance towards other faiths risks repeating the “horrors” of the Holocaust.
Speaking on BBC Radio 4’s religious Thought for the Day slot, the prince delivered an outspoken attack against religious hatred and pleaded for a welcoming attitude to those fleeing persecution.
He said: “We are now seeing the rise of many populist groups across the world that are increasingly aggressive to those who adhere to a minority faith. All of this has deeply disturbing echoes of the dark days of the 1930s.
“My parents’ generation fought and died in a battle against intolerance, monstrous extremism and inhuman attempts to exterminate the Jewish population of Europe.”
The prince did not mention any politicians by name, but his address will be seen by some as a veiled reference to the election of Donald Trump in the US, the rise of the far right in Europe, and increasingly hostile attitudes to refugees in the UK.
“That nearly 70 years later we should still be seeing such evil persecution is to me beyond all belief,” he said. “We owe it to those who suffered and died so horribly not to repeat the horrors of the past.” [Continue reading…]
Fredrik Albritton Jonsson writes: As a child growing up in the early 1980s, I often daydreamed of space exploration and interstellar frontiers. The leap into outer space seemed tantalizingly close. In the science fiction stories I read, the chronology of the future was also the potential biography of adulthood. One story projected a settlement on Mars in 1995; another depicted the grim labor of asteroid mining a decade later; a third imagined an encounter with alien artifacts in the Alpha Centauri system after 2020. The common thread in these stories, easily intuited even by an 11-year-old, was the lesson that the Earth was not our home.
Now the science fiction dream of leaving the planet behind appears to be coming true. One of the most striking effects of climate change — often remarked upon by writers — is its power to unsettle our basic understanding of the modern world. Our planet is changing into a strange and unstable new environment, in a process seemingly outside technological control. The fossil fuels that once promised mastery over nature have turned out to be tools of destruction, disturbing the basic biogeochemical processes that make our world habitable. Even the recent past is no longer what we thought it was. Scientists are telling us that the whole territory of modern history, from the end of World War II to the present, forms the threshold to a new geological epoch.
Our new planet is emerging quickly. The global climate is only one of nine earth system processes under threat. Land use is changing rapidly thanks to urbanization, agriculture, and population pressure. The rate of biodiversity loss is increasing in many ecosystems. Acidification is affecting marine biodiversity as well as the capacity of oceans to absorb carbon dioxide. The supply of fresh water in many regions is deteriorating. Aerosol loading and ozone depletion threaten the stability of the earth system’s atmosphere. Industrial agriculture has perturbed the global nitrogen and phosphorus cycles. Finally, chemical pollution may pose a risk not just at the local or regional level but also worldwide. Indeed, the planet’s biosphere bears so many marks of anthropogenic influence that it no longer possible to uphold the age-old distinction between the realm of wilderness and the world of human habitation.
To call attention to this unprecedented danger, the atmospheric chemist Paul Crutzen and the ecologist Eugene Stoermer in 2000 proposed a new name for the geological epoch we inhabit: the Anthropocene. For the first time, humans have become the prime drivers of the planetary climate. We have left behind the relatively stable pattern of natural variability that governed the environment in the Holocene epoch, beginning some 11,700 years ago. In the original formulation, Crutzen and Stoermer picked 1784 as the origin of the new epoch: the year of James Watt’s patent for a steam engine with a separate condenser. Britain’s early transition into the fossil fuel economy marked the end of the Holocene. More recently, the Working Group on the Anthropocene, established to validate the epoch in formal stratigraphic terms, has shifted the chronology of the Anthropocene from the Industrial Revolution to the Great Acceleration—the economic boom after World War II.

Charles Leadbeater writes: Heidegger detested René Descartes’s dictum ‘I think, therefore I am’ which located the search for identity in our brains. There, it was secured by a rational process of thought, detached from a physical world that presented itself to the knowing subject as a puzzle to be solved. Descartes’s ideas launched a great inward turn in philosophy with the subject at the centre of the drama confronting the objective world about which he tries to gain knowledge.
Had Heidegger ever come up with a saying to sum up his philosophy it would have been: ‘I dwell, therefore I am.’ For him, identity is bound up with being in the world, which in turn means having a place in it. We don’t live in the abstract space favoured by philosophers, but in a particular place, with specific features and history. We arrive already entangled with the world, not detached from it. Our identity is not secured just in our heads but through our bodies too, how we feel and how we are moved, literally and emotionally.
Instead of presenting it as a puzzle to be solved, Heidegger’s world is one we should immerse ourselves in and care for: it is part of the larger ‘being’ where we all belong. As [Jeff] Malpas puts it, Heidegger argues that we should release ourselves to the world, to find our part in its larger ebb and flow, rather than seek to detach ourselves from it in order to dominate it.

Nathan Collins writes: With climate change and deforestation threatening biodiversity around the world, it’s fair to wonder just how rapidly threatened species have been declining, and when exactly those declines began. The answer is bleak: Among threatened vertebrates, rapid losses began in the late 19th century, and numbers have since declined by about 25 percent per decade, according to a new study.
“Although preservation of biodiversity is vital to a sustainable human society, rapid population decline (RPD) continues to be widespread” across plant and animal populations, Haipeng Li and a team of Chinese and American biologists write in Proceedings of the National Academy of Sciences.
Understanding the severity and origins of these population losses could help conservationists protect endangered species and possibly help promote public awareness of the threat, the researchers argue. But there’s a problem: Good data on plant and animal population sizes only goes back about four decades, and populations surely declined prior to that.
Fortunately, modern biologists have a way to circumvent that: DNA. [Continue reading…]
G. Owen Schaefer writes: Would you want to alter your future children’s genes to make them smarter, stronger, or better looking? As the state of science brings prospects like these closer to reality, an international debate has been raging over the ethics of enhancing human capacities with biotechnologies such as so-called smart pills, brain implants, and gene editing. This discussion has only intensified in the past year with the advent of the CRISPR-cas9 gene editing tool, which raises the specter of tinkering with our DNA to improve traits like intelligence, athleticism, and even moral reasoning.
So are we on the brink of a brave new world of genetically enhanced humanity? Perhaps. And there’s an interesting wrinkle: It’s reasonable to believe that any seismic shift toward genetic enhancement will not be centered in Western countries like the US or the UK, where many modern technologies are pioneered. Instead, genetic enhancement is more likely to emerge out of China.
Numerous surveys among Western populations have found significant opposition to many forms of human enhancement. For example, a recent Pew study of 4,726 Americans found that most would not want to use a brain chip to improve their memory, and a plurality view such interventions as morally unacceptable.

By David Farrier, Aeon, October 31, 2016
Late one summer night in 1949, the British archaeologist Jacquetta Hawkes went out into her small back garden in north London, and lay down. She sensed the bedrock covered by its thin layer of soil, and felt the hard ground pressing her flesh against her bones. Shimmering through the leaves and out beyond the black lines of her neighbours’ chimney pots were the stars, beacons ‘whose light left them long before there were eyes on this planet to receive it’, as she put it in A Land (1951), her classic book of imaginative nature writing.
We are accustomed to the idea of geology and astronomy speaking the secrets of ‘deep time’, the immense arc of non-human history that shaped the world as we perceive it. Hawkes’s lyrical meditation mingles the intimate and the eternal, the biological and the inanimate, the domestic with a sense of deep time that is very much of its time. The state of the topsoil was a matter of genuine concern in a country wearied by wartime rationing, while land itself rises into focus just as Britain is rethinking its place in the world. But in lying down in her garden, Hawkes also lies on the far side of a fundamental boundary. A Land was written at the cusp of the Holocene; we, on the other hand, read it in the Anthropocene.
The Anthropocene, or era of the human, denotes how industrial civilisation has changed the Earth in ways that are comparable with deep-time processes. The planet’s carbon and nitrogen cycles, ocean chemistry and biodiversity – each one the product of millions of years of slow evolution – have been radically and permanently disrupted by human activity. The development of agriculture 10,000 years ago, and the Industrial Revolution in the middle of the 19th century, have both been proposed as start dates for the Anthropocene. But a consensus has gathered around the Great Acceleration – the sudden and dramatic jump in consumption that began around 1950, followed by a huge rise in global population, an explosion in the use of plastics, and the collapse of agricultural diversity.
The Sixth Extinction: Two-thirds of global wildlife population expected to be lost by the end of this decade
Marco Lambertini, Director General,WWF International, writes [PDF]: The evidence has never been stronger and our understanding never been clearer. Not only are we able to track the exponential increase in human pressure over the last 60 years — the so-called “Great Acceleration” and the consequent degradation of natural systems, but we also now better understand the interdependencies of Earth’s life support systems and the limits that our planet can cope with.
Take biodiversity. The richness and diversity of life on Earth is fundamental to the complex life systems that underpin it. Life supports life itself. We are part of the same equation. Lose biodiversity and the natural world and the life support systems, as we know them today, will collapse. We completely depend on nature, for the quality of the air we breathe, water we drink, climate stability, the food and materials we use and the economy we rely on, and not least, for our health, inspiration and happiness.
For decades scientists have been warning that human actions are pushing life on our shared planet toward a sixth mass extinction. Evidence in this year’s Living Planet Report supports this. Wildlife populations have already shown a concerning decline, on average by 58 per cent since 1970 and are likely to reach 67 per cent by the end of the decade. [Continue reading…[PDF]]
