Footprints found at White Sands National Park in New Mexico provide the earliest unequivocal evidence of human activity in the Americas and offer insight into life over 23,000 years ago.
The footprints were formed in soft mud on the margins of a shallow lake that now forms part of Alkali Flat, a large playa at White Sands. Researchers from the U.S. Geological Survey dated these tracks using radiocarbon dating of seed layers above and below the footprint horizons. The dates range in age and confirm human presence over at least two millennia with the oldest tracks dating from around 23,000 years ago, Continue reading →
Save The Waves Coalition and Pronatura Noroeste achieve approval for Arroyo San Miguel
In a historic moment for environmental and surf conservation, the first state park in Baja California, Mexico was officially approved, providing long-lasting protection for the iconic San Miguel wave alongside 67 hectares of green space.

Protecting species from extinction has been a running theme in our pages over the years. Underlying these many stories was an assumption, at least on our part, that defining boundaries between species is settled science. We will no longer take that for granted:
By studying crows, a German biologist has helped to solve a centuries-old mystery.
The evolutionary biologist Jochen Wolf was working from home when we first spoke, in April, 2020. Germany was under lockdown, and his lab, at Ludwig Maximilian University, in Munich, had been closed for weeks. Still, a reminder of his research had followed him from the office. “I have a crow nest right in front of me,” Wolf said, from his rooftop terrace. The nest was well hidden at the top of a tall spruce tree. Through the branches, Wolf could see a female crow sitting on her eggs. Continue reading →
Goats made their first appearance in our pages as a matter of pure visual fun. Then there were several in a row that touched on companionship as well as culinary aspects. Finally one treated goats as workers. That was five years ago. Today Coral Murphy Marcos tells the story, with photographs by Amanda Lucier, about a family, plus one intern, at the cutting edge of fighting fire with appetite:
As winter fades each year, cam viewers anticipate the return of the Barred Owls to their springtime residence in Zionsville, Indiana. Activity at the nest box in late February signaled the owls’ preparations for the new breeding season. It wasn’t long before the female laid two pearly white eggs in the nest box in early March.

Thanks to Civil Eats, after a while, for bringing Nan Kohler and her mission to our attention:
Elementary students processing whole wheat pasta with the wheat they harvested that season from their school’s wheat garden.
A new project in California aims to purchase mills for school cafeterias, marking the next step in years-long effort to bring local, whole grains to schools around the country.
Nan Kohler founded the milling company Grist & Toll in Pasadena, California in 2013 and her freshly milled flours have been a hit with bakers, chefs, and locavores ever since. But her abiding wish is to sell California-grown, freshly milled whole grain flour, which is nutritionally superior to refined flour, to the public schools in the area. Continue reading →
How Heather Wolf, a part-time juggling impresario, turned her birding habit into an app that pegs species—even on the Brooklyn Bridge—using both images and birdsong.
Heather Wolf earned a degree in sociology at U.C.L.A., then spent six years playing electric bass in a travelling band. She earned a master’s degree in information science, moved to Brooklyn, and worked as a software developer for a company based in Manhattan. Continue reading →
Small farmer and rubber tapper, Rogerio Mendes, 23: “I have an inexplicable feeling inside the forest. Because it’s a feeling of happiness, but with agony and concern.”
On a rainy March afternoon, Rogério Mendes strides through the dripping vegetation of a tract of virgin Amazonian forest and stops at a tree with scars arranged in neat diagonal rows across its trunk. From his back pocket he produces a wood-handled tool with a blade on one end, called a cabrita, and cuts another diagonal line though the bark, beneath the others. A milky white goo—raw liquid latex—begins to trickle down this tiny canal and into a metal pail below. Continue reading →
The richest university in the world capitulates after a decade of activism
The end came, as ends often do, quietly: at midafternoon today Harvard president Larry Bacow released a letter to Harvard students, faculty, and alumni. He didn’t use the word ‘divestment’–that would have been too humiliating–but he did say that the richest university on earth no longer had any direct investments in fossil fuel companies, and that its indirect investments through private equity funds would be allowed to lapse. “HMC has not made any new commitments to these limited partnerships since 2019 and has no intention to do so going forward. These legacy investments are in runoff mode and will end as these partnerships are liquidated.” Continue reading →
The video above is the shortest, clearest primer we could find to explain how this machine technology works. With Orca now on we will get the chance to see how much promise this process holds for carbon capture’s machine approach versus the tree approach, which we now know needs some reconsideration:
Operators say the Orca plant can suck 4,000 tonnes of CO2 out of the air every year and inject it deep into the ground to be mineralised

The world’s largest plant designed to suck carbon dioxide out of the air and turn it into rock has started running, the companies behind the project said on Wednesday.
The plant, named Orca after the Icelandic word “orka” meaning “energy”, consists of four units, each made up of two metal boxes that look like shipping containers.
Constructed by Switzerland’s Climeworks and Iceland’s Carbfix, when operating at capacity the plant will draw 4,000 tonnes of carbon dioxide out of the air every year, according to the companies. Continue reading →
Crowther says Restor is his ‘life’s vision’, mapping the latest data and thousands of conservation projects. Photograph: Courtesy of Restor
I have been on a tree-planting spree in the last couple years. So I am constantly on the lookout for resources that help me see this work in a larger context. Here is a great one I have just learned about. Restor’s macro-level organizing of conservation through geographic information systems requires skills and ambitions that few have in such capacity as the scientist featured in the following story. Maps like the one shown above are less inspirational, but more powerful in other ways, than scenes of effective restoration like the one below.

T. W. Crowther has featured in our pages for years, starting with our link to his work on how many trees are on our planet and what this implies with regard to climate. We lunged forward to share the idea that planting a trillion trees was the key implication, and also lurched back a bit when it seemed worthy of more consideration. This article does much to clear up “the mess” that Mr. Crowther acknowledges resulted from the trillion tree findings, and which I was captivated by:
Researchers are finding that when pulverized rock is applied to agricultural fields, the soil pulls far more carbon from the air and crop yields increase. More studies are underway, but some scientists say this method shows significant benefits for farmers and the climate.

On a hot and humid August day near Geneva, New York, Garrett Boudinot stands in a field of hemp, the green stalks towering a foot or more over his 6-foot, 4-inch frame. Today, the mustached Cornell University research assistant will harvest six acres of the crop, weigh it in red plastic garbage bins, and continue to analyze the hundreds of water samples taken with measuring devices called lysimeters that have been buried in the field over the last three months.

Boudinot, part of a research team at Cornell University, will sweat through the next two days of field work to see whether an unusual component added to the soil earlier in the year helped increase yields and sequester carbon. This soil amendment “we just call lovingly ‘rock dust,’ which isn’t very descriptive,” says Boudinot. “But it’s really silicate rocks that have been pulverized to a fine powder.” Continue reading →
Dealing with global warming is always going to be about the balance of power.
Amore personal note than usual this week, because this will be the last of these Climate Crisis columns I’ll write (though it’s not the end of my work for the magazine). I’m incredibly grateful to The New Yorker for letting me do them—and especially thankful for Virginia Cannon, who has edited them each week with grace and aplomb. Our run has overlapped almost perfectly with the course of the pandemic, and for me it’s been the perfect moment to sit back and appreciate and highlight the work of so many across the wide universe of activists, scientists, economists, and politicians who are taking on the deepest problem that humans have ever wandered into. I can’t overstate the comfort of that universe: it didn’t exist thirty-two years ago, when I started writing about climate change; its slow but inexorable rise has given me not just welcome company but real hope. I’ve particularly enjoyed “passing the mic” to many members of that gathering throng. Continue reading →

It is a no-brainer to oppose Line 3, but mere opposition does not amount to much. Action is the thing. And action is not always as cumbersome as it may sound. For example, if you bank with the people who are bullish on the future of oil, and who mix your money up with that money, it is time to rethink that relationship. Pull your money out of that bank:
“Greenwashing” is too kind a term; this is more like careful sabotage.
Travellers arriving in an unfamiliar city used to worry that they’d climb in a taxi and be driven to their destination by the most circuitous route possible, racking up an enormous bill. That’s pretty much what Big Oil and its allies in government and the financial world are doing with the climate crisis—in fact, at this point, it’s the heart of the problem. Continue reading →
Next month, an industrial facility in Iceland will join a growing number of projects to remove CO2 from the air and put it underground. But major hurdles, including high costs, remain before this technology can be widely deployed and play a key role in tackling climate change.
Climeworks’ Orca plant under construction near Reykjavik, Iceland. CLIMEWORKS
In early September, at an industrial facility located about 25 miles southeast of Reykjavik, Iceland, the Swiss company Climeworks will mark the opening of a new project named “Orca.” At least in a conventional sense, Orca doesn’t actually make anything. It is comprised of eight elongated boxes that resemble wood-clad tanks. Each of these boxes — known as “collectors” — is roughly the size of a tractor trailer, and each is festooned with 12 whirring fans that draw a stream of air inside. Within the collectors, a chemical agent known as a sorbent will capture CO2 contained in the air wafting through. Continue reading →
Free stuff is the zenith of the gardener’s life, the soil tender’s greatest thrill.
I may tell myself that I chat up my neighbors out of a post-quarantine craving for connection. I can pretend that I haul myself outside for a swift ten thousand steps because I’ve finally learned the value of tending myself, body and spirit. But the truth is that I have one motivation for every social interaction, city walk, or strenuous cycle ride: free stuff. Continue reading →
Scientists predict hotter heat waves and worse flooding in the decades ahead, but the catastrophe is evident everywhere this summer.
Illustration by João Fazenda
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 →
20 years after planting, this palm has reached for the sun, and found it.
When we completed construction on our home late in the year 2000, we had a small palm tree in a planter on our terrace. It was perhaps two feet tall at the time. Sometime in 2001 we planted that palm to the side of the house, and ever since it has been reaching for the sun. The opening sentence in the article below, combined with the photo from the same article that I have inserted with it, struck a chord. We need to think about this tree’s future in a way we did not when choosing where to plant it 20 years ago. My thanks to Margaret Roach– who wrote the article and is the creator of the website and podcast A Way to Garden, and a book of the same name–for this:
Many people find trees a little enigmatic. But there is help for the asking. (And it’s free.)
Younger, container-grown trees will settle in and start growing faster than field-dug specimens that may take three to five years to reestablish root systems and resume growth. The Morton Arboretum
The biggest plants in our gardens often get the smallest share of our attention. And it’s not because trees don’t need or want attention — or because we intend to neglect them.
Maybe it’s because they look so strong, holding most of their foliage overhead and not making their needs known near ground level, where we are busy paying attention to everyone else. Or maybe we just don’t have much tree-care confidence.
Indigenous women in North and Central America are coming together to share ancestral knowledge of amaranth, a plant booming in popularity as a health food

Just over 10 years ago, a small group of Indigenous Guatemalan farmers visited Beata Tsosie-Peña’s stucco home in northern New Mexico. In the arid heat, the visitors, mostly Maya Achì women from the forested Guatemalan town of Rabinal, showed Tsosie-Peña how to plant the offering they had brought with them: amaranth seeds.
Back then, Tsosie-Peña had just recently come interested in environmental justice amid frustration at the ecological challenges facing her native Santa Clara Pueblo – an Indigenous North American community just outside the New Mexico town of Española, which is downwind from the nuclear facilities that built the atomic bomb.
