Antarctica’s Thwaites Glacier ice shelf could collapse within five years

Antarctica’s Thwaites Glacier ice shelf could collapse within five years

Science News reports: The demise of a West Antarctic glacier poses the world’s biggest threat to raise sea levels before 2100 — and an ice shelf that’s holding it back from the sea could collapse within three to five years, scientists reported December 13 at the American Geophysical Union’s fall meeting in New Orleans. Thwaites Glacier is “one of the largest, highest glaciers in Antarctica — it’s huge,” Ted Scambos, a glaciologist at the Boulder, Colo.–based Cooperative Institute for Research…

A billion shellfish and other marine animals baked to death

A billion shellfish and other marine animals baked to death

Julia Rosen writes: During this summer’s stifling heat wave, Robin Fales patrolled the same sweep of shore on Washington’s San Juan Island every day at low tide. The stench of rotting sea life grew as temperatures edged toward triple digits—roughly 30 degrees above average—and Fales watched the beds of kelp she studies wilt and fade. “They were bleaching more than I had ever seen,” recalls Fales, a Ph.D. candidate and marine ecologist at the University of Washington. She didn’t know…

How one society rebounded from ‘the worst year to be alive’

How one society rebounded from ‘the worst year to be alive’

Michael Price writes: It was the worst time to be alive, according to some scientists. From 536 C.E. to 541 C.E., a series of volcanic eruptions in North and Central America sent tons of ash into the atmosphere, blocking sunlight, chilling the globe, and destroying crops worldwide. Societies everywhere struggled to survive. But for the Ancestral Pueblo people living in what today is the U.S. Southwest, this climate catastrophe planted the seeds for a more cohesive, technologically sophisticated society, a…

Nurdles — the worst toxic waste you’ve probably never heard of

Nurdles — the worst toxic waste you’ve probably never heard of

The Guardian reports: When the X-Press Pearl container ship caught fire and sank in the Indian Ocean in May, Sri Lanka was terrified that the vessel’s 350 tonnes of heavy fuel oil would spill into the ocean, causing an environmental disaster for the country’s pristine coral reefs and fishing industry. Classified by the UN as Sri Lanka’s “worst maritime disaster”, the biggest impact was not caused by the heavy fuel oil. Nor was it the hazardous chemicals on board, which…

New study links major fashion brands to Amazon deforestation

New study links major fashion brands to Amazon deforestation

The Guardian reports: New research into the fashion industry’s complex global supply chains shows that a number of large fashion brands are at risk of contributing to deforestation in the Amazon rainforest, based on their connections to tanneries and other companies involved in the production of leather and leather goods. The report, released Monday, analyzed nearly 500,000 rows of customs data and found that brands such as Coach, LVMH, Prada, H&M, Zara, Adidas, Nike, New Balance, Teva, UGG and Fendi…

Ten million deaths a year

Ten million deaths a year

David Wallace-Wells writes: Not​ all deaths are created equal. In February 2020, the world began to panic about the novel coronavirus, which killed 2714 people that month. This made the news. In the same month, around 800,000 people died from the effects of air pollution. That didn’t. Novelty counts for a lot. At the start of the pandemic, it was considered unseemly to make comparisons like these. But comparing the value of human lives is one thing the machine of…

How Norilsk, Siberia, became one of the most polluted places on Earth

How Norilsk, Siberia, became one of the most polluted places on Earth

Marianne Lavelle reports: It was 2 a.m. and the sun was shining, as it does day and night in mid-July in Norilsk, a Siberian city 200 miles north of the Arctic Circle. Igor Klyushin went to the bank of the river where he used to fish with his father for grayling, a sleek and dorsal-finned beauty known for its graceful leaps above the water surface. “A very merry fish,” Klyushin recalled. “It enjoys cold and clean, clean water.” He doubted…

Pesticides harmful to bees in worse ways than previously thought

Pesticides harmful to bees in worse ways than previously thought

Science reports: Honey bees have a reputation for working hard, but carpenter bees and other bee species that don’t live in colonies might be even more industrious. For these so-called solitary bees, there is no dedicated worker class to help with rearing young and foraging. “Each female is kind of like a lone wolf,” says Clara Stuligross, a Ph.D. student at the University of California (UC), Davis. Now, a study by Stuligross and colleagues tallying the detrimental impacts of a…

Canada’s tar sands: Destruction so vast and deep it challenges the existence of land and people

Inside Climate News reports: The first mine opened when Jean L’Hommecourt was a young girl, an open pit where an oil company had begun digging in the sandy soil for a black, viscous form of crude called bitumen. She and her family would pass the mine in their boat when they traveled up the Athabasca River, and the fumes from its processing plant would sting their eyes and burn their throats, despite the wet cloths their mother would drape over…

Junk food is bad for plants, too

Junk food is bad for plants, too

Anne Biklé and David R. Montgomery write: Most of us are familiar with the much-maligned Western diet and its mainstay of processed food products found in the middle aisles of the grocery store. Some of us beeline for the salty chips and others for the sugar-packed cereals. But we are not the only ones eating junk food. An awful lot of crops grown in the developed world eat a botanical version of this diet—main courses of conventional fertilizers with pesticide…

What to learn from hedgerows

What to learn from hedgerows

Katarina Zimmer writes: Hedgerows are as British as fish and chips. Without these walls of woody plants cross-stitching the countryside into a harmonious quilt of pastures and crop fields, the landscape wouldn’t be the same. Over the centuries, numerous hedges were planted to keep in grazing livestock, and some of today’s are as historic as many old churches, dating back as far as 800 years. Today, Britain boasts about 700,000 kilometers (435,000 miles) of them, a length that surpasses that…

Should we rein cities in or embrace their biomorphic growth?

Should we rein cities in or embrace their biomorphic growth?

Josh Berson writes: Cities are hard on the body. We are all familiar now with how dense living facilitates the spread of airborne disease. But the stressors of urban life are manifold. They include air- and waterborne pollution, noise, heat, light – and an excess of social contact. Pollution represents, as a 2017 report by the Lancet Commission on pollution and health puts it, ‘the largest environmental cause of disease and premature death’ among humans, responsible, in 2015, for ‘three…

Why air pollution can trigger depression

Why air pollution can trigger depression

Inverse reports: You may be breathing dirty air right now. Nine out of ten people in the world live in areas with high levels of air pollutants, according to the World Health Organization. This is a problem for physical and mental health. In addition to its well-established relationships to cancer and respiratory and heart diseases, a growing trove of scientific evidence links air pollution with depression and other mental health disorders. A study published Monday in the Proceedings of the…

What is deforestation – and is stopping it really possible?

What is deforestation – and is stopping it really possible?

Patrick Greenfield writes: Forests and nature are centre stage at Cop26. On the second day of the Glasgow summit, world leaders are announcing a commitment to halting and reversing deforestation. As the second largest source of greenhouse gases after energy, the land sector accounts for 25% of global emissions, with deforestation and forest degradation contributing to half of this. But why do forests matter to the climate, and how can we halt deforestation? What is a forest? There are an…

Capitalism is killing the planet – it’s time to stop buying into our own destruction

George Monbiot writes: There is a myth about human beings that withstands all evidence. It’s that we always put our survival first. This is true of other species. When confronted by an impending threat, such as winter, they invest great resources into avoiding or withstanding it: migrating or hibernating, for example. Humans are a different matter. When faced with an impending or chronic threat, such as climate or ecological breakdown, we seem to go out of our way to compromise…
