Influential panel votes to recognize Earth’s new epoch: The Anthropocene

Comments 0 Comment

Nature reports: A panel of scientists voted this week to designate a new geologic epoch — the Anthropocene — to mark the profound ways in which humans have altered the planet. That decision, by the 34-member Anthropocene Working Group (AWG), marks an important step towards formally defining a new slice of the geologic record — an idea that has generated intense debate within the scientific community over the past few years. The panel plans to submit a formal proposal for…

Philip Ball writes: Who said this? “I’ve been having to say everywhere I go that there is no planet B, there is no escape hatch, there is no second Earth; this is the only planet we have.” If you’re a science fiction fan the answer might surprise you: it was the writer Kim Stanley Robinson, whose Mars trilogy is an ultimately utopian series of tales that describe the terraforming of Mars – planetary engineering to give it an Earth-like environment…

Humans are killing off most large wild animals as sixth mass extinction advances

Humans are killing off most large wild animals as sixth mass extinction advances

The Guardian reports: Humanity’s ongoing destruction of wildlife will lead to a shrinking of nature, with the average body size of animals falling by a quarter, a study predicts. The researchers estimate that more than 1,000 larger species of mammals and birds will go extinct in the next century, from rhinos to eagles. They say this could lead to the collapse of ecosystems that humans rely on for food and clean water. Humans have wiped out most large creatures from…

The New York Times reports: Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded. The 1,500-page report, compiled by hundreds of international experts and based on thousands of scientific studies, is the most exhaustive look yet at the decline in…

Robert Watson writes: A colleague recently described how fish would swim into her clothing when she was a child bathing in the ocean off the coast of Vietnam, but today the fish are gone and her children find the story far-fetched. Another recalled his experiences just last year in Cape Town – one of the world’s most attractive tourism and leisure destinations – when more than 2 million people faced the nightmare prospect of all taps, in every home and…

The Guardian reports: The world’s leading scientists will warn the planet’s life-support systems are approaching a danger zone for humanity when they release the results of the most comprehensive study of life on Earth ever undertaken. Up to 1m species are at risk of annihilation, many within decades, according to a leaked draft of the global assessment report, which has been compiled over three years by the UN’s leading research body on nature. The 1,800-page study will show people living…

Tom Chatfield writes: Plenty of creatures can communicate richly, comprehend one another’s intentions and put tools to intelligent and creative use: cetaceans, cephalopods, corvids. Some can even develop and pass on particular local practices: New Caledonian crows, for example, exhibit a “culture” of tool usage, creating distinct varieties of simple hooked tools from plants in order to help them feed. Only humans, however, have turned this craft into something unprecedented: a cumulative process of experiment and recombination that over mere…

Jacinda Ardern at Christchurch memorial: Only through our common humanity can we confront extremism

  New Zealand PM, Jacinda Ardern, said: To the global community who have joined us today, who reached out to embrace New Zealand, and our Muslim community, to all of those who have gathered here today, we say thank you. And we also ask that the condemnation of violence and terrorism turns now to a collective response. The world has been stuck in a vicious cycle of extremism breeding extremism and it must end. We cannot confront these issues alone,…

Jonathan Lambert writes: The experience of natural spaces, brimming with greenish light, the smells of soil and the quiet fluttering of leaves in the breeze can calm our frenetic modern lives. It’s as though our very cells can exhale when surrounded by nature, relaxing our bodies and minds. Some people seek to maximize the purported therapeutic effects of contact with the unbuilt environment by embarking on sessions of forest bathing, slowing down and becoming mindfully immersed in nature. But in…

No marine ecosystems left that are unaffected by plastic waste, study suggests

Comments 0 Comment

The Guardian reports: The world’s deepest ocean trenches are becoming “the ultimate sink” for plastic waste, according to a study that reveals contamination of animals even in these dark, remote regions of the planet. For the first time, scientists found microplastic ingestion by organisms in the Mariana trench and five other areas with a depth of more than 6,000 metres, prompting them to conclude “it is highly likely there are no marine ecosystems left that are not impacted by plastic…

By Leah Shaffer In January 2016, Cathryn Townsend set out to live among “the loveless people.” So named by anthropologist Colin Turnbull, the Ik are a tribe of some 11,600 hunter-gatherers and subsistence farmers living in an arid and harsh mountainous region of Uganda. Turnbull studied the Ik in the 1960s and famously characterized them as “inhospitable and generally mean” in his book The Mountain People. He documented how young children were abandoned to starve and how people would snatch…

World’s food supply under ‘severe threat’ from loss of biodiversity

The Guardian reports: The world’s capacity to produce food is being undermined by humanity’s failure to protect biodiversity, according to the first UN study of the plants, animals and micro-organisms that help to put meals on our plates. The stark warning was issued by the Food and Agriculture Organisation after scientists found evidence the natural support systems that underpin the human diet are deteriorating around the world as farms, cities and factories gobble up land and pump out chemicals. Over…

The Guardian reports: The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review. More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could…

Rising temperatures could melt most Himalayan glaciers by 2100, threatening the water supply of 25% of global population

Comments 0 Comment

The New York Times reports: Rising temperatures in the Himalayas, home to most of the world’s tallest mountains, will melt at least one-third of the region’s glaciers by the end of the century even if the world’s most ambitious climate change targets are met, according to a report released Monday. If those goals are not achieved, and global warming and greenhouse gas emissions continue at their current rates, the Himalayas could lose two-thirds of its glaciers by 2100, according to…

By Kensy Cooperrider For centuries, Inuit hunters navigated the Arctic by consulting wind, snow and sky. Now they use GPS. Speakers of the aboriginal language Gurindji, in northern Australia, used to command 28 variants of each cardinal direction. Children there now use the four basic terms, and they don’t use them very well. In the arid heights of the Andes, the Aymara developed an unusual way of understanding time, imagining the past as in front of them, and the future…
