Growing coffee provides income for about 15 percent of Ethiopia’s population and is the country’s top export. Climate change is likely to shrink the land suitable for coffee, thereby also hurting the livelihoods of many people. Courtesy of Emily Garthwaite
Change is almost never easy. Then there is climate change. Daunting, but we cannot stop considering the implications and the options. The planet may recover in geological time, the underlying logic of those who promote denial of the urgency, but plenty of people are at risk in real time, so no option but to keep focus.
Ethiopia gave the world Coffea arabica, the species that produces most of the coffee we drink these days. Today, the country is the largest African producer of Arabica coffee. The crop is the backbone of the country’s economy – some 15 million Ethiopians depend on it for a living. Continue reading →
Far below the surface of the ocean, off the coast of eastern Australia is an area simply known as “the abyss.” The largest and deepest habitat on the planet, the abyssal zone stretches well beyond Australia’s waters and spans half the world’s oceans — but it remains largely unexplored.

An onlooker watches an annular solar eclipse from New Mexico.
For the past few years it seems that August is the month to amaze and astonish on the astronomical front. Although the Perseid Meteor Shower happens annually, last year there were an unusually high number of meteor “outbursts” because Jupiter’s gravity has tugged some streams of comet material closer to Earth.
While solar eclipses aren’t technically rare, an annular solar eclipse is more so, when the moon is too far from Earth to obscure the sun completely, leaving the sun’s edges exposed and producing the ‘ring of fire’ effect. What’s particularly special about the upcoming August 21st eclipse is the path from which it can be viewed.
Sky-watchers across the United States are gearing up for the best cosmic spectacle in nearly a century, when a total solar eclipse will race over the entire country for the first time since 1918. On August 21, tens of millions of lucky people will be able to watch the moon completely cover the sun and turn day into night for a few fleeting minutes.
Recognizing its utility as a household cleaner, especially to remove grease, ammonia has a smell that is familiar to most of us. But, nearly all of the annual industrial production of ammonia goes into other products, especially nitrogen fertilizer. Some farms inject ammonia directly into the soil. Others apply urea or ammonium phosphate fertilizers made from ammonia. All aim to supplement the availability of nitrogen for crop growth. Not all the ammonia gets into the crop. Inadvertent losses of nitrogen from fertilizers to the atmosphere account for about ten percent of fertilizer applications across the USA. Some nitrogen is also lost in the runoff to streams and rivers. Continue reading →
Stanford Earth’s Rosemary Knight recently spearheaded a project to map underground freshwater resources and forecast the intrusion of saltwater into aquifers beneath the California coastal town of Marina. The project, a collaboration between Stanford, the Marina Coastal Water District, and Aqua Geo Frameworks, involved a low-flying helicopter towing a giant, instrument-laden fiberglass hoop that generated ground-probing magnetic fields that penetrated 1,000 feet beneath the surface.
Click the book image at the left to go Indie Bound, a community of independent local bookstores, or if you need more convincing, read the beautifully illustrated Challenging MainstreamThought About Beauty’sBig Hand in Evolution by James Gorman in the Science section of the New York Times. It is as much profile as review and asks:
Are aesthetic judgments about mates invariably tied to traits we see as adaptive and worth passing on Or, does beauty just ‘happen’?
Not long ago, a physicist at Stanford posed a rhetorical question that took me by surprise.
“Why is there so much beauty?” he asked.
Beauty was not what I was thinking the world was full of when he brought it up. The physicist, Manu Prakash, was captivated by the patterns in seawater made as starfish larvae swam about. But he did put his finger on quite a puzzle: Why is there beauty? Why is there any beauty at all? Continue reading →
This other post today reminds me of the value of geeking out from time to time. Most of my attention to coral reef comes from Phil Karp’s posts on this platform and I admit to preferring stories featuring real people and their entrepreneurial approaches to conservation. But science is the other best friend of conservation. Today my attention is turning to coffee, in advance of the arrival this week of an intern coming from Cornell University’s College of Agriculture and Life Sciences.
Just one of the many topics for an intern, with science and research on her side, to help us tackle over the next ten weeks, bird-friendly coffee has been on been on my mind in the last year but I have been waiting for the perfect moment to focus. Nothing like the arrival of an intern to focus your mind. And so today in my task-oriented wanderings I came across this website (click the banner above), which I loved immediately for sharing this news on capsules, but the rest of the site is a great resource for present purposes as well:
What will it take to build crops that can withstand future climate changes? A group of plant biologists think they might be on to a solution for soybeans. Using genetic engineering, they’ve created a plant whose yields remain unaffected by high-stress conditions. The key lies in a genetic tweak that makes the plant overexpress a particular enzyme, which is thought to boost the efficiency of their photosynthesis cycle and enhance seed production.

…Recognizable common names are often critical for species protection, but subspecies miss out on this public perception benefit. A new paper argues that standardized English names are key to conservation success for Australia’s fantastic avifauna, and creates a definitive list for every subspecies on the continent.

…In a study published Tuesday in the journal Proceedings of the Royal Society B, a team of researchers investigated gigantism in baleen whales, the filter-feeding leviathans that include blue whales, bowhead whales and fin whales. The marine mammals became jumbo-size relatively recently, they found, only within the past 4.5 million years. The cause? A climatic change that allowed the behemoths to binge-eat…
The number of written words in both is about the same, and the quality of writing is comparable, but the photos in the Times article magnify the words there by, it seems, a thousand times, which explains why we are linking to another whale scale story a second day in a row:

Contrary to popular belief, moving from monoculture to smaller farms and a more diversified agricultural landscape isn’t necessarily a cure-all to the excessive use of insecticides on crops such as grapes and almonds. Continue reading →
HOBART, TASMANIA — John A. Church, a climate scientist, did not look or sound like a man who had recently been shoved out of a job.
Speaking softly and downing coffee at an outdoor cafe in this old port city, he sounded more like a fellow fresh off a jousting match. “I think we had a win — a bigger win than I ever anticipated,” Dr. Church said in an interview last month.
Australian climate science went through an upheaval last year, one that engaged the press and the public in defending the importance of basic research. In the end, Dr. Church did indeed lose his job, but scores of his colleagues who had been marked for layoffs did not. Some of them view him as having sacrificed his career to save theirs.
What happened in Australia shows the power of an informed citizenry keeping watch on its government. And it may turn out to be a precursor to an attack on fundamental climate research in the United States.
We have a mycological leaning on this platform, which started due to Milo’s interest, which was infectious. So, our news filters pick up stories like this; normally I avoid sharing the stories involving hallucinogens, though I read the serious ones myself. I do not expect stories like this one below from New York Magazine, so this was a pleasant surprise:
Last month, around 2,500 people with some connection to hallucinogenic drugs gathered at the Oakland Marriott City Center in Oakland, California for what might best be described as the psychedelics state of the union. Psychedelic Science 2017, as it was more formally known, drew professionals of all stripes: chemists who make the hallucinogens, neuroscientists who study their effects on the brain, therapists who discuss their after-effects on patients, shamans and healers who administer the drugs, and anthropologists like Joanna Steinhardt, who are trying to make sense of the meaning of psychedelic culture.

Three of our favorite topics in one, thanks to Joanna Klein, the New York Times, and Science (the section of the paper and the thing itself):
PISGAH NATIONAL FOREST, N.C. — Here’s what I was told: Get away from the city, go during a new moon and keep my flashlight off. When the sky faded black enough to spot stars twinkling, I’d be able to see mushrooms glowing. Continue reading →
There’s a transformation underway in how people think about plants: not just as inanimate biological objects, but as capable of perceptions and actions that resemble the intelligent behaviors of animals. Continue reading →
Camera traps are never going to lose our fascination, and have played a mitigating role in our non-Luddite but still determined effort to keep it simple, back to nature. The future depends on innovation, and we cannot hide behind trees pretending otherwise. If conservation efforts are going to compete effectively against the forces supporting environmental destruction, unconventional approaches are needed. We are entrepreneurially-inclined, and so are naturally comfortable with FishFace, among seven innovative pivots to a better future described by the wonderful team at Cool Green Science:
In our still relatively brief existence, humans have evolved our way to an era many are now calling the Anthropocene – a new geological epoch defined by human impact on Earth. But our unparalleled creativity is a double-edge sword. We are undeniably contributing to many of the global challenges now facing our species, and all species who share this planet.

Believe it or not, there is some good news out there on the carbon footprint trail. Thanks to Mathis Wackernagel, whose work I have appreciated even without posting more since 2011, and to his whole team for sharing this:
The US per capita Ecological Footprint dropped nearly 20% during the last eight years of available data (2005 and 2013), a total reduction that matches the entire Footprint of Germany. Continue reading →
The dependence of modern agriculture on pesticides is a growing environmental problem, causing soil and water contamination, threatening wildlife, and severely harming human health. Increasingly, experts are pondering whether we really need to be applying pesticides with such reckless abandon to our crops. A group of researchers now says no: in fact, we could significantly reduce pesticide use and still maintain current productivity on most farms, they assert. Continue reading →
