Personalising the ‘silent killer’ hot spells could raise awareness in time to avert loss of life and property, say scientists
Spurred on by this summer’s record temperatures, Greek scientists have begun discussing the need to name and rank heatwaves, better known for their invisibility, before rampant wildfires made the realities of the climate crisis increasingly stark.
A preventative measure, the move would enable policymakers and affected populations to be more prepared for what are being described by experts as “silent killers.” Continue reading
Efforts to minimize the concern about climate change have been concerted for decades, particularly by corporations and ideologues. At the same time there have been plenty of people who have taken the crisis seriously, and have worked tirelessly to get the rest of us on board. Deniers, doubters, those who sow doubt, and anyone else who wants to claim they know better than the scientists, here is one more comment on the recent report (even if few of us will read that report in its entirety):
Scientists predict hotter heat waves and worse flooding in the decades ahead, but the catastrophe is evident everywhere this summer.
In 1988, the World Meteorological Organization teamed up with the United Nations Environment Programme to form a body with an even more cumbersome title, the Intergovernmental Panel on Climate Change, or, as it quickly became known, the I.P.C.C. The I.P.C.C.’s structure was every bit as ungainly as its name. Any report that the group issued had to be approved not just by the researchers who collaborated on it but also by the governments of the member countries, which today number a hundred and ninety-five. The process seemed guaranteed to produce gridlock, and, by many accounts, that was the point of it. (One of the architects of the I.P.C.C. was the Reagan Administration.) Continue reading
Oil from the tar sands of Alberta will sink us faster than we are already sinking. How important is it to keep it where it is? Akin to some sort of holy grail. Thanks to Bill McKibben, as always, for weekly reminders to keep our eyes on the prize:
If the province’s oil is dug up and burned, it will be calculably harder to limit the damage from climate change.
Some weeks ago, the government of Alberta wrote to me—and apparently to a number of other environmentalists and environmental groups. We are all subjects of an “anti-Alberta energy inquiry,” and have the right to respond to charges that are being levelled by a government commission. Alberta, it turns out, has spent three and a half million dollars in an effort to find out whether foreigners are unfairly targeting its oil-and-gas industry. I’m mentioned dozens of times in the draft report, due to be finished this week, and it contains links to lots of articles of mine explaining why the province’s vast tar-sands project should be curtailed.

This week’s newsletter ponders how adaptable we are and serves as a reminder that we cannot take for granted that we are sufficiently so for the changes upon us:
Rising air temperatures remind us that our bodies have real limits.
By Bill McKibben
It’s hard to change the outcome of the climate crisis by individual action: we’re past the point where we can alter the carbon math one electric vehicle at a time, and so activists rightly concentrate on building movements large enough to alter our politics and our economics. But ultimately the climate crisis still affects people as individuals—it comes down, eventually, to bodies. Which is worth remembering. In the end, we’re not collections of constructs or ideas or images or demographics but collections of arteries and organs and muscles, and those are designed to operate within a finite range of temperatures. Continue reading
Thanks to Public Broadcasting Service (USA) for this:
The threat was invisible to the eye: tons of methane billowing skyward, blown out by natural gas pipelines snaking across Siberia. In the past, those plumes of potent greenhouse gas released by Russian petroleum operations last year might have gone unnoticed. But armed with powerful new imaging technology, a methane-hunting satellite sniffed out the emissions and tracked them to their sources.
Thanks to rapidly advancing technology, a growing fleet of satellites is now aiming to help close the valve on methane by identifying such leaks from space. The mission is critical, with a series of recent reports sounding an increasingly urgent call to cut methane emissions. Continue reading
Again, exceptional infographics tell an important environmental story–it is worth opening if only for the quality of the interactive illustrations:
The warming atmosphere is causing an arm of the powerful Gulf Stream to weaken, some scientists fear.
By MOISES VELASQUEZ-MANOFF
and JEREMY WHITE
IT’S ONE OF THE MIGHTIEST RIVERS you will never see, carrying some 30 times more water than all the world’s freshwater rivers combined. In the North Atlantic, one arm of the Gulf Stream breaks toward Iceland, transporting vast amounts of warmth far northward, by one estimate supplying Scandinavia with heat equivalent to 78,000 times its current energy use. Without this current — a heat pump on a planetary scale — scientists believe that great swaths of the world might look quite different. Continue reading
The announcement this week from the Canadian company TC Energy that it was pulling the plug on the Keystone XL pipeline project was greeted with jubilation by Indigenous groups, farmers and ranchers, climate scientists and other activists who have spent the last decade fighting its construction.
The question now is whether it will be a one-off victory or a template for action going forward — as it must, if we’re serious about either climate change or human rights. Continue reading
Thanks, Damian Carrington, for getting us the data that Morales-Caselles et al compiled making us wonder whether convenience is worth this cost:
Just 10 plastic products make up 75% of all items and scientists say the pollution must be stopped at source
Plastic items from takeaway food and drink dominate the litter in the world’s oceans, according to the most comprehensive study to date. Continue reading
We knew a bit about almonds being very thirsty trees, but when you see the trees being uprooted, it becomes even more real. The questions surrounding drought are too much for a short article, so thanks to one of our favored science writers, Henry Fountain, for keeping this focused:
Answers to questions about the current situation in California and the Western half of the United States.
Much of the Western half of the United States is in the grip of a severe drought of historic proportions. Conditions are especially bad in California and the Southwest, but the drought extends into the Pacific Northwest, much of the Intermountain West, and even the Northern Plains.
Drought emergencies have been declared. Farmers and ranchers are suffering. States are facing water cutbacks. Large wildfires are burning earlier than usual. And there appears to be little relief in sight.
What is a drought, exactly?
There are no precise parameters that define a drought, but it is generally understood to mean a period of abnormally dry weather that goes on for long enough to have an impact on water supplies, farming, livestock operations, energy production and other activities. Continue reading
For all the attention we have given palm oil in the decade of posting links to stories here, strange that Jocelyn Zuckerman only appears once in our pages before today. As with fossil fuels the onus should not be entirely on individuals as consumers; collective action and public policy are essential tools to limiting the damage that corporate palm interests have been causing, relatively unchecked, for too long. We thank her for this clear, strong statement:
The cultivation of palm oil, found in roughly half of U.S. grocery products, has devastated tropical ecosystems, released vast amounts of C02 into the atmosphere, and impoverished rural communities. But efforts are underway that could curb the abuses of this powerful industry.
A few weeks ago, the Sri Lankan president announced that his government would ban all imports of palm oil, with immediate effect, and ordered the country’s plantation companies to begin uprooting their oil-palm monocultures and replacing them with more environmentally friendly crops. Citing concerns about soil erosion, water scarcity, and threats to biodiversity and public health, President Gotabaya Rajapaksa explained that his aim was to “make the country free from oil palm plantations and palm oil consumption.” Continue reading
Thanks to the New York Times for this coverage of the choices surrounding how and where to mine a key ingredient of more efficient batteries–a consequential environmental question:
A race is on to produce lithium in the United States, but competing projects are taking very different approaches to extracting the vital raw material. Some might not be very green.
Atop a long-dormant volcano in northern Nevada, workers are preparing to start blasting and digging out a giant pit that will serve as the first new large-scale lithium mine in the United States in more than a decade — a new domestic supply of an essential ingredient in electric car batteries and renewable energy.
The mine, constructed on leased federal lands, could help address the near total reliance by the United States on foreign sources of lithium.
But the project, known as Lithium Americas, has drawn protests from members of a Native American tribe, ranchers and environmental groups because it is expected to use billions of gallons of precious ground water, potentially contaminating some of it for 300 years, while leaving behind a giant mound of waste.

Stewardship has rights and responsibilities, and we expect better both from and for Brazil in their stewardship of the Amazon region. For our part, among other things, we can all avoid purchasing products that result from this deforestation:
International team of researchers also found that deforestation rose nearly four-fold in 2019
The Brazilian Amazon released nearly 20% more carbon dioxide into the atmosphere over the past decade than it absorbed, according to a startling report that shows humanity can no longer depend on the world’s largest tropical forest to help absorb manmade carbon pollution.
From 2010 through 2019, Brazil’s Amazon basin gave off 16.6bn tonnes of CO2, while drawing down only 13.9bn tonnes, researchers reported Thursday in the journal Nature Climate Change. Continue reading
They’re purple, spiky and voracious, and just off the West Coast, there are more of them than you can count.
Purple sea urchins have exploded in recent years off California, covering the ocean floor in what divers describe as a “purple carpet.” Continue reading
First things first. The last time I linked out to a book based on a podcast interview with the author, it turned into a complaint about the podcast’s link to Amazon for finding the book. This time the same podcast, interviewing another author about his recently published book, is linking to the book’s publisher instead of to Amazon. Click the image to go there. Progress. The book sounds like a perfect fit with our interests on this platform, and the quality of conversation with the author makes the episode itself worth listening to in advance of reading the book:
The acclaimed food writer offers a sweeping indictment of our modern food system.
Mark Bittman taught me to cook. I read his New York Times cooking column, “The Minimalist,” religiously. Continue reading
One of the many things that humans have been doing for a long time that are going to have to change:
Dragging heavy nets across seabed disturbs marine sediments, world’s largest carbon sink, scientists report
Fishing boats that trawl the ocean floor release as much carbon dioxide as the entire aviation industry, according to a groundbreaking study.
Bottom trawling, a widespread practice in which heavy nets are dragged along the seabed, pumps out 1 gigaton of carbon every year, says the study written by 26 marine biologists, climate experts and economists and published in Nature on Wednesday. Continue reading
We have not featured any of her work since this review of H is for Hawk but we are happy to read Helen Macdonald’s work again with this review:
UNDER A WHITE SKY
The Nature of the Future
By Elizabeth Kolbert
A few years ago YouTube recommended I watch a video with the word “carpocalypse” in its title. I clicked the link — of course I did — and stared in awe at what resembled a mash-up of a video game, nature documentary and war movie. I saw a river full of fish leaping from the water like chaotic piscine fireworks and men in speedboats yelling and holding out nets to catch them as if they were wet and weighty butterflies. Fish hitting people in the face, fish landing in boats, fish flapping between people’s feet in a mess of slime and blood. Continue reading
