Although not quite an example of “Model Mad“, this culinary entrepreneurial activism sends a message to both consumers and food industry colleagues alike.
Karen Leibowitz and Anthony Myint opened the Perennial in San Francisco last year with a clear mission in mind: Run an environmentally friendly restaurant with a minimal carbon footprint, and inspire other restaurateurs to do the same.
As [the current administration] has questioned the existence of climate change, Ms. Leibowitz and Mr. Myint have emerged as activists, at the forefront of a growing movement of chefs who not only recognize and measure the impact of their industry on the planet, but also look for new ways to undo the damage.
Mr. Myint and Ms. Leibowitz, who are married, have been immersed for the last few years in the research that directs every decision at the restaurant, like choosing the kitchen’s energy-efficient equipment and its raw ingredients, many of which are grown in ways that can regenerate the soil.

Once again we thank NYTimes Science writer Justin Gillis for this primer on a complex and politically weighty issue.
We know. Global warming is daunting. So here’s a place to start: 17 often-asked questions with some straightforward answers.
1.Climate change? Global warming? What do we call it?
Both are accurate, but they mean different things.
You can think of global warming as one type of climate change. The broader term covers changes beyond warmer temperatures, such as shifting rainfall patterns.
President Trump has claimed that scientists stopped referring to global warming and started calling it climate change because “the weather has been so cold” in winter. But the claim is false. Scientists have used both terms for decades.
2.How much is the Earth heating up?
Two degrees is more significant than it sounds.
As of early 2017, the Earth had warmed by roughly 2 degrees Fahrenheit (more than 1 degree Celsius) since 1880, when records began at a global scale. The number may sound low, but as an average over the surface of an entire planet, it is actually high, which explains why much of the world’s land ice is starting to melt and the oceans are rising at an accelerating pace. If greenhouse gas emissions continue unchecked, scientists say, the global warming could ultimately exceed 8 degrees Fahrenheit, which would undermine the planet’s capacity to support a large human population.
3.What is the greenhouse effect, and
how does it cause global warming?
We’ve known about it for more than a century. Really.
In the 19th century, scientists discovered that certain gases in the air trap and slow down heat that would otherwise escape to space. Carbon dioxide is a major player; without any of it in the air, the Earth would be a frozen wasteland. The first prediction that the planet would warm as humans released more of the gas was made in 1896. The gas has increased 43 percent above the pre-industrial level so far, and the Earth has warmed by roughly the amount that scientists predicted it would.
A recent study found that the value of jaguars to tourism (US$6,827,392) was far in excess of the cost to ranchers from depredation of their cattle (US$121,500)
The intersection between jaguar territory and tourism has been part of our work for decades, in both the Paraguayan Pantanal, Costa Rica’s Osa Peninsula and more recently in northwestern Belize.
We’ve seen the efficacy of species protection via conservation tourism when the economic value of species survival is quantified. This is good news for one of our favorite animals.
From villain to hero, the jaguar (Panthera onca) stands at the cusp of a radical overhaul in its public image. As the largest cat in the Americas, the species commands a dominant role in the food chain of its native Pantanal – a vast swathe of tropical wetland that encompasses parts of Brazil, Paraguay and Bolivia. Once hunted for its fur, the jaguar’s appetite for the abundant prey in the Pantanal has led it into deadly conflict with ranchers in recent decades, casting it as the stalking menace of livestock and livelihood in a region where much of the land is reserved for cattle rearing. However, in a hopeful development for conservationists, researchers have revealed in a new study published in Global Ecology and Conservation that jaguars are worth 60 times more to tourism than the cost the big cats inflict on ranchers.
“The study represents a regional reality in the Pantanal,” said Fernando Tortato, research fellow at Panthera, the global wild cat conservation group that helped lead the study. “Where the jaguar brings in far more revenue than the potential damage it can cause.”
Jaguars once abounded from the southwestern U.S. to Argentina, but their numbers have fallen due to hunting and habitat loss. In the Amazon rainforest, deforestation is an ongoing threat, even while the dense foliage often precludes human encounters with jaguars. In the absence of benign tourism opportunities there is demand for jaguar teeth, paws and claws as souvenirs.
But jaguar’s predilection for lush and low-lying forest makes the Pantanal a stronghold for the species. The wetland’s web-like tributaries also open the wild cat’s home to human exploration, allowing tourists to share in their company.
In the Pantanal, the biggest threat to their survival is conflict with ranchers. Continue reading

Tapping into a long, intertwined history of “photographers depicting nature with an eye to its fragility”, multimedia artist Justin Brice Guariglia translates his unprecedented access to NASA mission flights to visually quantify what is currently coined the Anthropocene Era.
Readers lucky enough to have the opportunity to view his coming exhibition, at the Norton Museum of Art in West Palm Beach, Fla., from Sept. 5 to Jan. 7 should do so!
Earlier this year at the Telluride Mountainfilm Festival, the artist Justin Brice Guariglia fell into conversation with a stranger.
“I got stuck on a gondola ride with a climate change denier,” Mr. Guariglia said recently. The stranger clearly had no idea who he was dealing with.
Not only had Mr. Guariglia previously talked his way into joining a NASA scientific mission over Greenland so that he could photograph melting polar ice caps. He also had even created a mobile app called After Ice, which allows users to take a selfie that is overlaid with a watery filter indicating the sea level projected in their geo-tagged location in the 2080s.
So when the man on the gondola said the earth’s warming temperatures were just part of a cycle, Mr. Guariglia recalled, “I took off my jacket and I said, ‘Does this look like a cycle to you?’” Continue reading
Wade Dooley, in Albion, Iowa, uses less fertilizer than most farmers because he grows rye and alfalfa, along with corn and soybeans. “This field [of rye] has not been fertilized at all,” he says.
Thanks to National Public Radio (USA) and Dan Charles for doing their job, keeping the questions coming, even on topics we think we know the answers to:
Brent Deppe is taking me on a tour of the farm supply business, called Key Cooperative, that he helps to manage in Grinnell, Iowa. We step though the back door of one warehouse, and our view of the sky is blocked by a gigantic round storage tank, painted white.
“This is the liquid nitrogen tank,” Deppe explains. “It’s a million-and-a-half gallon tank.” Continue reading

Thanks to Brad Plumer and the commitment of the New York Times to continue covering the complex topic of climate change in interesting, and sometimes hopeful ways:
In the 1980s, an ecologist named Thomas Lovejoy conducted an unusual experiment in Brazil’s Amazon rain forest. As loggers moved in with chain saws to clear trees for cattle pasture north of Manaus, he asked them to leave untouched several small “islands” of forest to see how the animals within them fared.
The results were unsettling. Continue reading
This animation shows where the 21 species in the study occur during each week of the year. Brighter colors (yellows) indicate more species are present than darker areas (blues and purples); overall, the species spend more time in Central American wintering grounds than on their northern breeding grounds. Map and animation by Frank La Sorte.
Once again eBird data and the Cornell Lab of Ornithology studies highlight the importance of forest conservation for species survival, as seen in Climate Change Or Habitat Loss? Study Weighs Future Priorities For Conserving Forest Migrants:
Birds are among the first to let us know when the environment is out of whack. But predicting what might happen to bird populations is tricky. Studies often focus on a single issue or location: breeding grounds or wintering grounds, changes in climate, loss of habitat. But in the real world, nothing occurs in isolation. A new study just published in the journal Global Change Biology pulls the pieces together. Continue reading
For a second day in a row, a butterfly story catches our attention. Small stories of unexpected good fortune are always welcome:

Thanks to John Abraham, and the Guardian’s team focused on the Environment, for shining the light on the good works of those who work to ensure our access to essential environmental science at a time when there are efforts to silence the science:

Chile’s near catastrophe with hydroelectric energy, averted in part thanks to the efforts of friends in the Patagonia Sin Represas campaign, made us wonder whether Chile’s path to a greener future would be straight and narrow. Thanks to the New York Times and Ernesto Londoño we think we have strong evidence helping us with the answer:
CERRO PABELLÓN, Chile — It looks and functions much like an oil drilling rig. As it happens, several of the men in thick blue overalls and white helmets who operate the hulking machine once made a living pumping crude.

With the ability to power roughly 165,000 homes, the new plant is yet another step in Chile’s clean energy transformation. This nation’s rapidly expanding clean energy grid, which includes vast solar fields and wind farms, is one of the most ambitious in a region that is decisively moving beyond fossil fuels.

Latin America already has the world’s cleanest electricity, having long relied on dams to generate a large share of its energy needs, according to the World Bank.
But even beyond those big hydropower projects, investment in renewable energy in Latin America has increased 11-fold since 2004, nearly double the global rate, according to a 2016 report by the International Renewable Energy Agency, an intergovernmental organization. Chile, Mexico and Brazil are now among the top 10 renewable energy markets in the world.
So as Latin America embraces greener energy sources, government officials and industry executives in the region have expressed a sense of confusion, even bewilderment, with the Trump administration’s decision to withdraw from the climate changecommitments contained in the Paris Agreement, declare an end to the “war on coal” and take aim at American environmental regulations.

Thanks to the Conversation for highlighting the potential of this inspiring technology.
Bren Smith, an ex-industrial trawler man, operates a farm in Long Island Sound, near New Haven, Connecticut. Fish are not the focus of his new enterprise, but rather kelp and high-value shellfish. The seaweed and mussels grow on floating ropes, from which hang baskets filled with scallops and oysters. The technology allows for the production of about 40 tonnes of kelp and a million bivalves per hectare per year. Continue reading

Thanks to Alan Burdick for illuminating some of the silver linings of the otherwise cloudy prospects of melting glaciers:
In the past century, the glaciers and ice fields of the European Alps have lost half their volume to global warming, and their continued retreat, like that of glaciers everywhere in the world, is accelerating. By 2100, many scientists predict, they will have all but disappeared. The meltdown has already disrupted the region’s sensitive mountain ecosystems and tourist resorts—some local communities have taken to laying protective white blankets over the snow and ice—but it has also opened up new avenues of scientific inquiry.

We appreciate California’s heroic measures to take responsibility and show leadership where it can on climate change:
Over the past decade, California has passed a sweeping set of climate laws to test a contentious theory: that it’s possible to cut greenhouse gas emissions far beyond what any other state has done and still enjoy robust economic growth.
Now that theory faces its biggest test yet. Last August, the State Legislature set a goal of slashing emissions more than 40 percent below today’s levels by 2030, a far deeper cut than President Barack Obama proposed for the entire United States and deeper than most other countries have contemplated.
So how will California pull this off? Continue reading

Thanks to the New York Times for this refresher on the basics of climate change and what is needed that we can most easily do to counter its effects:
By Brad Plumer
The tropical forests in western Uganda, home to a dwindling population of endangered chimpanzees, are disappearing at some of the fastest rates on Earth as local people chop down trees for charcoal and to clear space for subsistence farming.
Now, a team of researchers has shown that there is a surprisingly cheap and easy way to slow the pace of deforestation in Uganda: Just pay landowners small sums not to cut down their trees. Their study, published in the journal Science on Thursday, demonstrated this by conducting something all too rare in environmental policy — a controlled experiment. Continue reading

Thanks again to the New York Times for highlighting the global nature of this scientific “call to arms” to save not only data, but genetic and organic material as a back-up plan for future generations. From the Svalbard Global Seed bank in Norway, to sperm banks for coral, endangered wildlife, and even glacial ice – these archives are meant to provide both a life line to the future and answers about the past.
The fragility of each project is evident as Science itself has come under attack from current public policy, which doesn’t appear to see the irony of their denial in the face of facts about climate change.
It was a freakishly warm evening last October when a maintenance worker first discovered the water — torrents of it, rushing into the entrance tunnel of the Svalbard Global Seed Vault, a storage facility dug some 400 feet into the side of a mountain on a Norwegian island near the North Pole. A storm was dumping rain at a time of year when the temperature was usually well below freezing; because the water had short-circuited the electrical system, the electric pumps on site were useless. This subterranean safe house holds more than 5,000 species of essential food crops, including hundreds of thousands of varieties of wheat and rice. It was supposed to be an impenetrable, modern-day Noah’s ark for plants, a life raft against climate change and catastrophe.
A few Norwegian radio stations and newspapers reported the incident at the time, but it received little international attention until May, when it was becoming clear that President Trump was likely to pull the United States out of the Paris climate agreement. Suddenly the tidings from Svalbard were everywhere, in multiple languages, with headlines like “World’s ‘Doomsday’ Seed Vault Has Been Breached by Climate Change.” It didn’t matter that the flood happened seven months earlier, or that the seeds remained safe and dry. We had just lived through the third consecutive year of the highest global temperatures on record and the lowest levels of Arctic ice; vast swaths of permafrost were melting; scientists had recently announced that some 60 percent of primate species were threatened with extinction. All these facts felt like signposts to an increasingly hopeless future for the planet. And now, here was a minifable suggesting that our attempts to preserve even mere traces of the bounty around us might fall apart, too.

At Chan Chich Lodge we are aware that the half million acres of forest surrounding us are essential habitat not just for the specific jaguars, pumas, ocelots, margays and jaguarundis we have the good fortune to see with some frequency. Rather, that scale of acreage is essential for species survival. We are in a large forest corridor that is increasingly rare and unfortunately fragile in other locations throughout the Americas where they still exist. We do what we do with that in mind. Thanks to Ed Yong, at the Atlantic, for this context on extinction:
Imagine if every animal and plant on the planet collapsed into a single population each, says ecologist Gerardo Ceballos. If lions disappeared except from one small corner of Kenya, the prey they keep in check would run amok everywhere else. If sparrows were no more except in one Dutch forest, the seeds that sparrows disperse would stay in place everywhere else. If honeybees became isolated to one American meadow, the flowers that they pollinate would fail to reproduce everywhere else. None of those species would be extinct per se, “but we’d still be in very bad shape,” says Ceballos. Continue reading
Mangroves play an essential role in maintaining healthy life on earth, and we’ve been privileged to work in many locations where we’ve seen their impact on biodiversity levels first-hand, including India.
Frequently these ecosystems are under threat of habitat loss, whether for agricultural or land development. Thanks again to Anthropocene for adding up the facts in such clear terms.
Conservationists frequently say that ecosystems are worth more when they’re left untouched. But to whom? Local communities who could potentially farm the land might wonder, what’s the real benefit of leaving wild areas intact?
In the Bhitarkanika mangrove in Odisha, India, a group of Indian researchers grappling with this question have arrived at a surprising answer. By leaving the mangrove intact, they say, Bhitarkanika’s surrounding communities can in fact reap almost double the economic benefits they’d get from simply converting the mangrove to crops.

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.

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.
Thanks to the salt, at National Public Radio (USA) for a reminder of coffee‘s relationship with conservation, a reminder of Ethiopia in general, which is always welcome, and especially Ethiopia’s relationship with one of our favorite beverages:
by Courtney Columbus
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
