How the salvation of New York City drinking water can be a model for saving the planet

How the salvation of New York City drinking water can be a model for saving the planet

Michael Heller and James Salzman write: [Al] Appleton is a bear of a man with a quick wit and disarming candor. In 1990, he became Commissioner of the New York City Department of Environmental Protection and Director of the City’s Water and Sewer system. He immediately faced a dilemma. Unlike most big American cities, New York did not have treatment plants for its tap water. Showing great foresight in the early 1900s, the City had laid huge pipes from the…

The Amazon rainforest could die in your lifetime — here’s why

The Amazon rainforest could die in your lifetime — here’s why

Anna Funk writes: Deforestation in the Amazon has long been the poster child of man-made environmental destruction. But recent trends reveal that the changing climate will likely come for this beloved rainforest long before the last tree is cut down. One researcher has even put a date on his prediction for the Amazon’s impending death: 2064. That’s the year the Amazon rainforest will be completely wiped out. Dramatic? Yes. “I’m a doom-sayer,” admits Robert Walker, a quantitative geographer at the…

A critically endangered bird is losing its song

A critically endangered bird is losing its song

Brisbane Times reports: When Michael Alfa was setting up to photograph wildlife at Woolgoolga’s sewage works near the northern NSW town of Coffs Harbour last year, the avid birdwatcher could hardly believe his senses. There, among the warbling wattlebirds hanging off a coastal banksia tree, was a lone, critically endangered regent honeyeater, distinctive in its yellow and black plumage. But not its birdsong. “It was making the exact same song [as the wattlebirds]. If you hadn’t seen it, you wouldn’t…

We are hurtling toward global suicide

We are hurtling toward global suicide

Ben Ehrenreich writes: On January 13, one week before the inauguration of Joe Biden as the forty-sixth president of the United States and seven long days after the storming of the Capitol by an armed right-wing mob, it was easy enough to miss an article published in the journal Frontiers in Conservation Science, despite its eye-catching title: “Underestimating the Challenges of Avoiding a Ghastly Future.” The headline was itself a train wreck: six dully innocuous words piling up in front…

How bacteria and archaea influence one of Earth’s largest carbon stores as it begins to thaw

How bacteria and archaea influence one of Earth’s largest carbon stores as it begins to thaw

Monique Brouillette writes: For most of human history, permafrost has been Earth’s largest terrestrial carbon sink, trapping plant and animal material in its frozen layers for centuries. It currently stores about 1,600 billion tonnes of carbon — more than twice the amount in the atmosphere today. But thanks to rising temperatures, permafrost is fracturing and disappearing, leaving behind dramatic changes in the landscape. Scientists are becoming increasingly worried that the thaw will lead to an epic feast for bacteria and…

Electric cars’ looming recycling problem

Electric cars’ looming recycling problem

By Perry Gottesfeld In September, Tesla announced that it would be phasing out the use of cobalt in its batteries, in an effort to produce a $25,000 electric vehicle within three years. If successful, this bold move will be an industry game changer, making electric vehicles competitive with conventional counterparts. But the announcement also underscores one of the fundamental challenges that will complicate the transition to electric vehicles. Without cobalt, there may be little financial incentive to recycle the massive…

Brood X cicadas are about to put on one of the wildest shows in nature. And D.C. is the main stage

Brood X cicadas are about to put on one of the wildest shows in nature. And D.C. is the main stage

The Washington Post reports: They’ve been buried — alive — for 17 years. And now, Brood X, one of the world’s largest swarms of giant fly-like bugs called cicadas, is ready to rise. When the ground warms to 64 degrees, they’ll stop gnawing on tree roots and start scratching toward the surface by the hundreds of billions. Georgia and other Southern states will probably be where they first emerge around the end of March, experts say. But residents of the…

We can’t plant or log our way out of climate change

We can’t plant or log our way out of climate change

Danna Smith writes: CNN published an opinion piece on Feb. 10 with the headline, “Plant trees, sure. But to save the climate, we should also cut them down.” This piece omitted some vital facts and science. While the piece did not call for a broad expansion of logging, I think it’s important for readers to understand these facts. Industrial logging and wood production are major drivers of climate disruption. The US is the world’s largest consumer and producer of wood…

Atlantic Ocean circulation at weakest in a millennium, say scientists

Atlantic Ocean circulation at weakest in a millennium, say scientists

The Guardian reports: The Atlantic Ocean circulation that underpins the Gulf Stream, the weather system that brings warm and mild weather to Europe, is at its weakest in more than a millennium, and climate breakdown is the probable cause, according to new data. Further weakening of the Atlantic Meridional Overturning Circulation (AMOC) could result in more storms battering the UK, more intense winters and an increase in damaging heatwaves and droughts across Europe. Scientists predict that the AMOC will weaken…

Very few of world’s rivers undamaged by humanity, study finds

Very few of world’s rivers undamaged by humanity, study finds

The Guardian reports: Rivers in which fish populations have escaped serious damage from human activities make up just 14% of the world’s river basin area, according to the most comprehensive study to date. Scientists found that the biodiversity of more than half of rivers had been profoundly affected, with big fish such as sturgeon replaced by invasive species such as catfish and Asian carp. Pollution, dams, overfishing, farm irrigation and rising temperatures due to the climate crisis are also to…

‘Invisible killer’: Fossil fuels caused 20 percent of deaths globally in 2018, research finds

The Guardian reports: Air pollution caused by the burning of fossil fuels such as coal and oil was responsible for 8.7m deaths globally in 2018, a staggering one in five of all people who died that year, new research has found. Countries with the most prodigious consumption of fossil fuels to power factories, homes and vehicles are suffering the highest death tolls, with the study finding more than one in 10 deaths in both the US and Europe were caused…

Are pandemics the cost of human recklessness towards nature?

Are pandemics the cost of human recklessness towards nature?

Piyush Nanda writes: In an area devastated by deforestation, an 18-month-old toddler from the nearest settlement, Meliandou in Guinea, was seen playing around a fallen tree swarming with bats. The child then contracted a mysterious illness, which spread to many who came in contact. After it had already killed 30 people, the illness was identified as Ebola. Comprehensive studies have since connected 25 of the 27 Ebola outbreaks in Africa, like the 2014 outbreak that originated in Guinea, to regions…

The ongoing collapse of the world’s aquifers

The ongoing collapse of the world’s aquifers

Matt Simon writes: As California’s economy skyrocketed during the 20th century, its land headed in the opposite direction. A booming agricultural industry in the state’s San Joaquin Valley, combined with punishing droughts, led to the over-extraction of water from aquifers. Like huge, empty water bottles, the aquifers crumpled, a phenomenon geologists call subsidence. By 1970, the land had sunk as much as 28 feet in the valley, with less-than-ideal consequences for the humans and infrastructure above the aquifers. The San…

Air pollution will lead to mass migration, say experts after landmark ruling

Air pollution will lead to mass migration, say experts after landmark ruling

The Guardian reports: Air pollution does not respect national boundaries and environmental degradation will lead to mass migration in the future, said a leading barrister in the wake of a landmark migration ruling, as experts warned that government action must be taken as a matter of urgency. Sailesh Mehta, a barrister specialising in environmental cases, said: “The link between migration and environmental degradation is clear. As global warming makes parts of our planet uninhabitable, mass migration will become the norm….
