A massive study solidifies the link between air pollution from cars and diabetes

A massive study solidifies the link between air pollution from cars and diabetes

Olga Khazan reports: It’s fairly well known that a bad diet, a lack of exercise, and genetics can all contribute to type 2 diabetes. But a new global study points to an additional, surprising culprit: the air pollution emitted by cars and trucks. Though other research has shown a link between diabetes and air pollution in the past, this study is one of the largest of its kind, and it’s unique because it both is longitudinal and includes several types…

What makes the new acting EPA chief even worse than Scott Pruitt

What makes the new acting EPA chief even worse than Scott Pruitt

Alexander C. Kaufman reports: Just one year ago, Andrew Wheeler worked as one of the coal industry’s most powerful lobbyists, serving as coal baron Bob Murray’s Capitol Hill muscle, challenging environmental regulations and casting doubt on the science behind climate change. On Monday, Wheeler will take over at the Environmental Protection Agency, after Administrator Scott Pruitt’s sudden resignation Thursday amid a five-month avalanche of ethics and legal controversies. Wheeler’s ascension, while expected to return stability to the scandal-struck EPA, demonstrates…

Robin McKie reports: When Simon Leather was a student in the 1970s, he took a summer job as a postman and delivered mail to the villages of Kirk Hammerton and Green Hammerton in North Yorkshire. He recalls his early morning walks through its lanes, past the porches of houses on his round. At virtually every home, he saw the same picture: windows plastered with tiger moths that had been attracted by lights the previous night and were still clinging to…

‘Shocking’ die-off of Africa’s oldest baobabs

‘Shocking’ die-off of Africa’s oldest baobabs

AFP reports: Some of Africa’s oldest and biggest baobab trees — a few dating all the way back to the ancient Greeks — have abruptly died, wholly or in part, in the past decade, researchers said Monday. The trees, aged between 1,100 and 2,500 years and some as wide as a bus is long, may have fallen victim to climate change, the team speculated. “We report that nine of the 13 oldest… individuals have died, or at least their oldest…

Humanity is a tiny fraction of life on Earth but has destroyed over 80% of wild mammals and half of plants

The Guardian reports: Humankind is revealed as simultaneously insignificant and utterly dominant in the grand scheme of life on Earth by a groundbreaking new assessment of all life on the planet. The world’s 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds. The new work is the first…

Someone, somewhere, is making a banned CFCs that destroys the ozone layer, scientists suspect

Comments 0 Comment

The Washington Post reports: Emissions of a banned, ozone-depleting chemical are on the rise, a group of scientists reported Wednesday, suggesting someone may be secretly manufacturing the pollutant in violation of an international accord. Emissions of CFC-11 have climbed 25 percent since 2012, despite the chemical being part of a group of ozone pollutants that were phased out under the 1987 Montreal Protocol. “I’ve been making these measurements for more than 30 years, and this is the most surprising thing…

Glyphosate shown to disrupt microbiome ‘at safe levels’, study claims

Comments 0 Comment

The Guardian reports: A chemical found in the world’s most widely used weedkiller can have disrupting effects on sexual development, genes and beneficial gut bacteria at doses considered safe, according to a wide-ranging pilot study in rats. Glyphosate is the core ingredient in Monsanto’s Roundup herbicide and levels found in the human bloodstream have spiked by more than a 1,000% in the last two decades. The substance was recently relicensed for a shortened five-year lease by the EU. But scientists…

Rising incomes result in expanding forests

Rising incomes result in expanding forests

Comments 0 Comment

BBC News reports: Forests are increasing around the world because of rising incomes and an improved sense of national wellbeing say researchers. The authors refute the idea that increasing levels of CO2 in the atmosphere are the key cause of the spread of trees. As countries become better off, farmers focus on good quality soils and abandon marginal lands, the authors say. As a result, trees are able to rapidly reforest these deserted areas. The study highlights the fact that…

Sharon Levy writes: Peter Moyle, an eminent authority on the ecology and conservation of California’s fishes, stands on the narrow deck of a survey boat and gazes out over the sloughs of Suisun Marsh. The tall, tubular stems of tule reeds bend in the wind as a flock of pelicans soars past, their white wings edged in black. It’s an idyllic scene that hints at an earlier time, back before the Gold Rush, when undisturbed creeks and tidal marsh covered…

By Bill Laurance, James Cook University The plan to build a massive hydropower dam in Sumatra as part of China’s immense Belt and Road Initiative threatens the habitat of the rarest ape in the world, which has only 800 remaining members. This is merely the beginning of an avalanche of environmental crises and broader social and economic risks that will be provoked by the BRI scheme.

Alaskan sea ice just took a steep, unprecedented dive

Alaskan sea ice just took a steep, unprecedented dive

Scientific American reports: April should be prime walrus hunting season for the native villages that dot Alaska’s remote western coast. In years past the winter sea ice where the animals rest would still be abundant, providing prime targets for subsistence hunters. But this year sea-ice coverage as of late April was more like what would be expected for mid-June, well into the melt season. These conditions are the continuation of a winter-long scarcity of sea ice in the Bering Sea—a…

How a Eurasian steppe empire coped with decades of drought

How a Eurasian steppe empire coped with decades of drought

Comments 0 Comment

By Diana Crow The bitterly cold, dry air of the Central Asian steppe is a boon to researchers who study the region. The frigid climate “freeze-dries” everything, including centuries-old trees that once grew on lava flows in Mongolia’s Orkhon Valley. A recent study of the tree-ring record, published in March, from some of these archaic logs reveals a drought that lasted nearly seven decades—one of the longest in a 1,700-year span of steppe history—from A.D. 783–850. Decades of prolonged drought…

Eric Holthaus writes: Lake Mead is the country’s biggest reservoir of water. Think of it as the savings account for the entire Southwest. Right now, that savings account is nearly overdrawn. For generations, we’ve been using too much of the Colorado River, the 300-foot-wide ribbon of water that carved the Grand Canyon, supplies Lake Mead, and serves as the main water source for much of the American West. The river sustains one in eight Americans — about 40 million people…

EU agrees total ban on bee-harming pesticides

The Guardian reports: The European Union will ban the world’s most widely used insecticides from all fields due to the serious danger they pose to bees. The ban on neonicotinoids, approved by member nations on Friday, is expected to come into force by the end of 2018 and will mean they can only be used in closed greenhouses. Bees and other insects are vital for global food production as they pollinate three-quarters of all crops. The plummeting numbers of pollinators…

David Grann writes: The man felt like a speck in the frozen nothingness. Every direction he turned, he could see ice stretching to the edge of the Earth: white ice and blue ice, glacial-ice tongues and ice wedges. There were no living creatures in sight. Not a bear or even a bird. Nothing but him. It was hard to breathe, and each time he exhaled the moisture froze on his face: a chandelier of crystals hung from his beard; his…
