Trees create habitat and store CO2 for decades to come. Just be sure to pick carefully.
One of the best ways to combat climate change is to fill your garden with as many trees, shrubs, and other plants as possible. Whether a tiny orchid or towering oak, all plants have the amazing ability to remove carbon dioxide from the atmosphere during photosynthesis and store it in their wood, shoots, and roots.
Because they’re the giants of the plant kingdom, trees are also powerhouses of carbon storage. In one year, a mature tree can absorb 48 pounds of CO2—about the amount emitted by driving 150 miles in a hybrid plug-in car. Collectively, according to the U.S. Forest Service, trees offset 10 to 20 percent of U.S. emissions from burning fossil fuels each year. The carbon benefits really begin to add up when you consider that trees fight global warming in other ways. For example, carefully placed trees can reduce the energy required to heat and cool a home by 25 percent (see tips here on how to place trees). Because they cool the air by casting shade and releasing water vapor when they breathe, trees also alleviate one of the most underestimated health threats of climate change—heat waves.

Somini Sengupta and her colleague Alexander Villegas published a story yesterday that resonates with the explanations Amie and I gave friends and family about our original decision to live in Costa Rica. It also resonates with the decision we made recently to return. In 2010 when we moved to Kerala it was not clear when, or even if, we would be back here. But our work in India was intertwined with Costa Rica’s evergreen pioneering role in the global conversation about conservation. So we are back. And the evergreen is appreciated, especially in the way Costa Rica’s president and his wife tell the story within a story.
Despite it’s diminutive size, Costa Rica been at the forefront of the climate change conversation. While the country has only about 0.25% of the world’s landmass, it contains almost 5% of the world’s biodiversity. These statistics give both an added incentive to focus energies on shifting the juggernaut of climate change and the ecological soapbox from which to be heard.
Costa Rica has an infrastructural uphill climb, most specifically with transportation as is illustrated below, but the country has stood its ground successfully in the past. When we think of the country’s road network in the mid-1990s relative to the roads today, it gives one of many reasons to be optimistic:
SAN JOSÉ, Costa Rica — It’s a green big deal for a tiny sliver of a country. Costa Rica, population 5 million, wants to wean itself from fossil fuels by 2050, and the chief evangelist of the idea is a 38-year-old urban planner named Claudia Dobles who also happens to be the first lady.

We’ve had friends and family members living in Atlanta for close to 30 years, and although I knew it was the hub of important aspects of American history, it never occurred to me to think of it in archaeological terms. At first consideration, I think about archaeology as the study of ancient cultures in far away places. Yet, with family in countries like Greece, I acknowledge that awesome layers of history can be just under the surface, or deeply buried and unearthed as cities grow with constructions of buildings and transit infrastructure.
This piece in the Georgia State University Magazine made that quite clear.
From its days as a railroad boomtown to Sherman’s tinderbox to one of America’s great cities, Atlanta’s history runs deep. The Phoenix Project, more than 100,000 artifacts collected by a team of Georgia State archaeologist in the 1970s, tells the city’s story through unearthed historical objects.
These boxes contain the lost pieces of a tumultuous past that dates to the city’s earliest days — bullet casings from the Civil War, mystery tonics in antique glass bottles, creepy toys, fashion accessories, ancient grooming tools and much more. Many of them still await examination and haven’t been opened since archaeologists first packed them four decades ago.
This massive array of objects is called the Phoenix Project, and Georgia State professors and students have been methodically studying, cataloging and mapping each item since 2011.
Collected all over the city between 1976 and 1980, the objects belong to the largest archeological collection ever associated with Atlanta. They are the fruit of one of America’s earliest urban archaeological projects — the roving excavation that followed construction crews as the Metropolitan Atlanta Rapid Transit Authority (MARTA) cleared land, leveled blocks and tunneled underground to build the first iteration of its rail system.
Jeffrey Glover, associate professor of anthropology, has curated the Phoenix Project for years in hopes of providing the public with a different kind of city history, a slice of Atlanta’s past through the lens of historical objects.
Choosing one box among hundreds, Glover removes a small amber bottle that once held Valentine’s Meat Juice, a concentrated beef tonic from the 1870s. Advertisements said it could help with gastroenteritis, dysentery and even cholera.
“It was supposed to bring vitality,” Glover says, “like an early energy drink.”
From another box, he takes out the misshapen head of a porcelain doll. Featuring dark, empty eye sockets and covered in burn marks, the scary toy looks hungry for souls. While Glover affectionately calls it the “creepy doll head,” its official artifact ID is “a3161,” written in impeccable script with archival ink across its neck.
That’s because the archaeologists who bagged all this stuff in the 1970s methodically described and organized each item using a numbering system adapted from the Georgia Department of Transportation. For example, the “a” in “a3161” stands for “general artifact” while the number indicates the item was the 3,161st general artifact to be cataloged from that accession. (And there are about 100 accessions.) Containers, such as glass and pottery, begin with “p,” and building materials with “m.” Plant remains use “eb” for “ethnobotanical” while animal bones start with “ez” for “ethnozoological.”
Just one of the standard cardboard bankers boxes can contain dozens, if not hundreds, of artifacts, each wrapped in brown paper and labeled with a unique artifact ID. Though they’ve all been recorded in a logbook alongside a one-line description, unwrapping each one is like opening a birthday present because you don’t know exactly what you’ll get.
“It’s an excavation of boxes,” says Lori Thompson (M.A. ’16), assistant laboratory director at New South Associates.
I remember car free days in Paris with pleasure, sunny autumn weather topped by cyclists, pedestrians and skaters enjoying wide boulevards and narrow city lanes alike. New York City has a smaller scale version, with a 2 mile stretch of lower Broadway, plus a mile up in Washington Heights.
No traffic days taking place in developing countries somehow feels all the more impactful, especially considering it’s a monthly event, rather than an annual one! Thanks to the BBC for bringing this to our attention with the story No traffic in Addis Ababa as Ethiopia marks Car Free Day:
Thousands of people have marked Car Free Day in cities across Ethiopia by walking and exercising.
Major roads were shut as Health Minister Amir Aman led the walk in the capital, Addis Ababa.
This was the first Car Free Day held in Ethiopia to promote healthy living, and to reduce pollution on roads usually clogged with traffic.
Tents were also set to offer free health checks to those who were walking and exercising.
Mr Amir is trying to change that and Car Free Day will be held on the last Sunday of each month, he adds. Continue reading
Thanks to Yale e360’s Mumbai-based Vaishnavi Chandrashekhar:
In India’s burgeoning urban areas, residents are rallying against the widespread destruction of trees to make way for development. The recent protests highlight a global issue: densely populated megacities in the developing world, which are most in need of tree cover, often have the least.
The funeral cortege was small. Six people shouldered the bier and others followed, clad in the traditional Indian white. As the group filed past the state assembly building, the armed guards did not give it a second glance. In a few minutes, however, the security forces caught on. The procession winding its way through Mumbai’s government district was not a real funeral: It was a protest. The shrouded body held aloft was not a human — it was the trunk of a tree, one of many, including grand old banyans, cut down for the construction of a $3.3 billion subway line.
Mumbai’s old trees have borne the brunt of new development in the booming city, including road widening, transport projects, and housing construction. The new subway alone is destroying or damaging 5,000 trees, from hundreds of old street trees in the dense parts of the historic island city to more than 2,000 trees in a mini-forest in suburban Aarey Colony, where a rail car shed is to be built. A less visible loss lies in defunct industrial areas, where large plots with old trees and ponds are being redeveloped into residential and commercial towers. “Developers are supposed to replace the trees but no one really checks,” says Stalin D., head of local environmental group, Vanashakti.

Katherine Bagley, Managing Editor at Yale Environment 360 (Yale e360, one of our go-to sources on this platform), has this to say:
The world’s cities are expected to grow by another 2.5 billion people by 2050. A new collection of satellite images starkly illustrates the sheer size and imprint of the world’s urban centers and their vulnerability in the face of population growth and climate change.
Driven by rapid economic expansion and global trade, the world’s urban population has more than quintupled since the mid-20th century, from 751 million people in 1950 to 4.2 billion today. Centuries-old cities have pushed upward and outward to accommodate the influx of people, and entirely new megacities, home to tens of millions, have sprung up.
Nowhere can this swift urban growth be seen as vividly as from space. In their new book City Unseen, geographers Karen C. Seto and Meredith Reba, experts in urbanization and global change, offer a collection of satellite images from all seven continents that exhibit the massive imprint these cities have on the landscapes around them.
“If you look at images of Las Vegas and Lagos and Shenzhen, you see how much land it takes to house billions people, and it’s astonishing,” Seto, a professor of geography and urbanization science at the Yale School of Forestry & Environmental Studies, says. “But the impact of urbanization is not only the direct land these people live on. It’s all these other non-urban places where we need to extract resources to house and electrify, to operate these cities. That’s part of the story too.” Continue reading
Thanks to Penelope Green for brightening up our Sunday:
In a world of climate change, creating a biome of one’s own.
Horticulture and red wine were served up the other night at the Sill, a boutique on Hester Street, as Christopher Satch, a botanist wearing a T-shirt that read, “Plants Make People Happy,” the company motto, led a workshop on carnivorous plants.
It was plant stand-up — slightly blue patter with quick takes on Linnaeus and Darwin; binomial nomenclature (note the shape of the Venus fly trap for cues to how it got its name); detailed care instructions (carnivorous plants evolved in acidic bogs, which means they need distilled water, not tap, and lots of it); and a show-and-tell of Mr. Satch’s collection of butterworts and sundews.
Among the rapt attendees were Madison Steinberg and Lindsay Reisman, both 23 and working in public relations, and Brayan Poma, also 23, who works in construction; afterward they each took home an attractive tropical pitcher plant. “I like plants, but I kill so many of them,” said Mr. Poma, who wore a green hoodie and a goatee. “Maybe that’s why I find them so alluring.”
Mr. Poma is not the only millennial to feel that allure. Buoyed by Instagram, his generation’s obsession with houseplants is growing faster and more tenaciously than English ivy. Plant influencers, the horticultural stars of that medium, now have book deals, sponsors and hundreds of thousands of followers.Their apartment living rooms are the new urban jungles, spilling over with philodendrons, pilea (this year’s “It” plant) and bird’s nest ferns. Plant parents, as they call themselves, fuss over their plant babies with the attention once given to kimchi or coffee connoisseurship. (Such anthropomorphism — ironic though it may be — recalls the 1970s, when “The Secret Life of Plants” proposed plant sentience based on dubious science and convinced New Agers to chat up their spider ferns.)
Unlike George Orwell, these houseplant lovers see the lowly aspidistra as an aspirational totem, not a bourgeois cliché, and post money shots of their monsteras on #monsteramonday. That hashtag was propagated in 2016 by Morgan Doane, a director of analytics for an art company in Florida. Continue reading
In our quest to brighten up each day with a story, a picture, or personal observation that helps us better understand the world around us, Doreen Carvajal is our source for this story in the New York Times from the former hometown of several of our long-time contributors:
PARIS — It’s a swift ride by elevator from Galeries Lafayette’s perfume section to the grand department store’s 10th-floor luxury farm with its signature scent of sage, rosemary and compost.
The rooftop garden, lush with climbing plants, tomatoes, marigolds and strawberries, is part of a plan to transform city farming into a deluxe shopping attraction for customers yearning for an exclusive green refuge — and perhaps a taste of beer brewed from the store’s homegrown hops.

Ugandans are finding creative solutions to the growing challenges of urbanisation
When Martin Agaba realised his urban farm had run out of space, he decided the solution was not to expand outwards but upwards.
“We realised we had to use the roof,” he says. Of all the innovations that have galvanised people in his district in the Ugandan capital Kampala to grow their own food, these vertical box plantations remain his favourite.
Kwagala farm, located on half an acre of land, is the brainchild of Diana Nambatya, a professor in public health, who began growing vegetables to save money on food in 2010.
After receiving two cows as a dowry, she decided to use their dung to generate biogas for her home. Her burgeoning urban farm soon attracted the attention of the neighbours, and in 2012 she started training women at a small demonstration centre. Continue reading
Aapnu Amdavad has a lot to boast about. From being the first city to have been declared India’s first Unesco World Heritage City to being home to some prime educational institutes, this city has gained prominence on the global map. Having said that, the city has its share of dark spots too. The fast diminishing green cover in the city is one of them. India’s fifth largest city has a tree cover of approximately 35 crores (as per a 2017 census), which although is 13% more than the number of trees in 2013, is still not enough. The ongoing metro project has also led to a lot of felling of trees. Taking into consideration all this, Ahmedabad Municipal Corporation (AMC) has decided to build vertical gardens in the city. It recently set up a small vertical garden along one of the pillars at the flyover at Helmet crossroads.
What are vertical gardens? Essentially vertical gardens are the kind of gardens that grow vertically, along walls or pillars, with the help of trellis (which are wooden frames) or similar support systems. Continue reading
Thanks to Redhouse Studio and the Guardian’s Laura Dorwart for this story:
Could a process that uses mycelium to help recycle old buildings into new ones solve the problem of the city’s many abandoned homes?
Over 7,000 abandoned or condemned homes litter the urban landscape of Cleveland, Ohio, where a stunning population loss of about 100,000 residents in 25 years and widespread foreclosures have sparked a housing crisis marked by growing racial and economic disparities. Posing concerns in terms of economic stability, public health and safety, the abandoned homes that line many of the city’s streets are at once symbols of its resilience and ongoing obstacles to growth and prosperity.
Cleveland native Christopher Maurer, founder and principal architect at local humanitarian design firm Redhouse Studio and adjunct professor at Kent State University, has plenty of ideas about how to address the city’s complex challenges.
Renaissance is a word that sounds like it means something good. But not necessarily so. Sarah Cowan has this review of a show in the Bronx that sounds worthy of a visit:
In the film “Day’s End,” the artist Gordon Matta-Clark rides a whale-size piece of corrugated metal as it is hoisted away from the wall from which he just cut it. He’s a young man, age thirty-two. The feat was filmed in the summer of 1975, in Chelsea’s abandoned Pier 52 building, where Matta-Clark attempted to make an “indoor park.” His silhouette, against the sunlight streaming in from his new view of the Hudson River, is heroic.

We do not normally link to the writing of science fiction authors, nor is the topic of the essay below typical of the themes in our 2011-2018. But it is not unheard of; nor is it too late to add more to this short thread of links to sci-fi authors. If Bruce Sterling catches your attention with these first few paragraphs pasted below, you may want to go to The Atlantic to read the rest:
Digital stardust won’t magically make future cities more affordable or resilient.
The term “smart city” is interesting yet not important, because nobody defines it. “Smart” is a snazzy political label used by a modern alliance of leftist urbanites and tech industrialists. To deem yourself “smart” is to make the nimbyites and market-force people look stupid.
Smart-city devotees all over this world will agree that London is particularly smart. Why? London is a huge, ungainly beast whose cartwheeling urban life is in cranky, irrational disarray. London is a god-awful urban mess, but London does have some of the best international smart-city conferences.
London also has a large urban-management bureaucracy who emit the proper smart-city buzzwords and have even invented some themselves. The language of Smart City is always Global Business English, no matter what town you’re in.
So if grand old London is smart, with its empty skyscrapers, creepy CCTV videocams, and sewers plugged with animal fat, then we probably needn’t fret about the Elon Musk sequins and stardust of digital urbanism. Better to reimagine the forthcoming urban future as a mirror of Rome, that “Eternal City,” where nothing much ever gets tech-fixed, but everything changes constantly so that everything can remain the same.

Thanks to Sierra magazine for bringing this to our attention:
A new report ranks the best and worst places to hop on the saddle
Do you live in the safest or the most dangerous state for riding a bike? The 2017 Bicycle Friendly State Report Card has the answer.
Each year, the League of American Bicyclists, an advocacy group founded in 1880 to improve street conditions for bikers, releases a detailed ranking that cyclists can use to track where it’s safe, and not so safe, to hop on wheels. The group also monitors each state’s progress toward increased bicycle safety. The rankings are derived from a variety of factors, including five key bicycle-friendly actions, federal data on bicycling conditions, and summaries with feedback on how each state can improve the safety and mobility of bicyclists.

We linked out to stories about bike-sharing when it was relatively new in New York. This week, an enchanting short note on a peddler of angelic behavior, and a couple examples of people who have pedaled accordingly:
A program offers modest benefits to riders who help rebalance the city’s network of bicycles. One man outdid its expectations.
By Ian Parker
On a recent Monday, Glenn Reinhart, a former salesman of chemicals for the cosmetics industry, and now, in his mid-fifties, a freelance karate instructor with a fair amount of leisure time, took twenty-two rides on Citi Bikes, one after another, and then went out to breakfast in Chelsea. He had arranged to meet Collin Waldoch, who runs Bike Angels, the Citi Bike program that awards points, redeemable for extended membership and other modest benefits (a commemorative pin; a white bike key), to riders who help the company rebalance its network of twelve thousand bikes. Angels earn points for taking bikes from full stations and parking them at empty ones. A ride from one to the other might earn two or three points. When the scheme was launched, this spring, Waldoch thought that someone might, in the course of a year, earn five hundred points. By the fall, Glenn Reinhart had earned nearly eight thousand—twice as many as anyone else—and Waldoch sent him an e-mail and invited him to breakfast. Continue reading
The scientific journal Nature is not one of our regular sources for stories here, but when the Science section of the Times points out a good story, we listen. To our surprise, even the Real Estate section of the Times can point out must-read stories from Nature (the slide show is worth the click):
There are 422 living trees for every human on Earth — 3.04 trillion overall — and during a couple of weeks each fall, a person can feel plainly outnumbered. Is it possible that a trillion of those trees have deposited their leaves in the front yard? And why are so many of them still green? Continue reading
Murals with birds always capture our attention; we cannot resist linking to such initiatives when they are cleverly conceived, elegantly executed, and perfectly placed. Enjoy this epic series, a fitting tribute to the National Audubon Society:
The Audubon Mural Project is a collaboration between the National Audubon Society and Gitler & Gallery to create murals of climate-threatened birds throughout John James Audubon’s old Harlem‐based neighborhood in New York City. The project is inspired by the legacy of the great American bird artist and pioneering ornithologist and is energized by Audubon’s groundbreaking Birds and Climate Change Report, which reveals at least half of all North American birds are threatened by a warming climate. The project commissions artists to paint murals of each of the report’s 314 species, and has been widely covered in the media, including most recently by The New York Times.
Thanks to the Editorial Board of the New York Times for reminding us of this:
In his final years, John James Audubon, the celebrated 19th-century painter of bird life, lived in rustic uptown Manhattan in a house by the Hudson where some of his final paintings were of urban rats that caught his eye. Continue reading
I’ve long been fascinated with urban space art installations in general, and fibre based pieces in particular. Somehow I missed hearing about the Singapore based i Light Marina Bay Light Art Festival in March, but I’m happy to have discovered it now.
The festival is an annual event, and this year’s theme of Biomimicry and Sustainability strike multiple chords. London/Seoul based architectural firm Choi+Shine created The Urchins for this site specific installation.
This project is inspired by sea urchin shells, which are enclosed yet light weight, delicate and open. Their textured and permeable surface interacting with light creates openness, while the pattern’s mathematical repetition brings visual rhythm and harmony. Against light, the sea urchin natural form reveals one of the most spectacular patterns found in nature. Continue reading
Thanks again to one of our most reliable sources for the summary of conservation-oriented science, and specifically to Brandon Keim for this one:
Even in one of the most densely urbanized places on Earth, wildness and natural abundance may yet flourish again, sustained by both neglect and stewardship. Continue reading
