Lungs Of The Earth, The Amazon Calls Our Attention Again
The Amazon is one of those big topics that we come back to again and again for a reason. We all depend on these lungs of the earth, so it would be strange to not be obsessed with the subject:
Has the Amazon Reached Its ‘Tipping Point’?
Some Brazilian scientists fear that the Amazon may become a grassy savanna — with profound effects on the climate worldwide.
One of the first times Luciana Vanni Gatti tried to collect Amazonian air she got so woozy that she couldn’t even operate the controls. An atmospheric chemist, she wanted to measure the concentration of carbon high above the rainforest. To obtain her samples she had to train bush pilots at obscure air-taxi businesses. The discomfort began as she waited on the tarmac, holding one door open against the wind to keep the tiny cockpit from turning into an oven in the equatorial sun. When at last they took off, they rose precipitously, and every time they plunged into a cloud, the plane seemed to be, in Gatti’s words, sambando — dancing the samba. Then the air temperature dipped below freezing, and her sweat turned cold. Continue reading

Time To Care About Climate Change

A pile of debris from Hurricane Ian rises behind a line of people waiting to vote in Fort Myers, Fla., in November 2022. Research suggests support for some climate policies increases immediately after climate-driven disasters such as Ian.

If you are not (yet) concerned about climate change there is no time like the present:
How our perception of time shapes our approach to climate change
Most people are focused on the present: today, tomorrow, maybe next year. Fixing your flat tire is more pressing than figuring out if you should use an electric car. Living by the beach is a lot more fun than figuring out when your house will be underwater because of sea level rise. Continue reading

The Heart Beat In Greece

I appreciate the comment about the heart beat in Katy Fallon’s portrait of a particular form of pastoral life in northern Greece. It comes just as we start dreaming of making an overdue visit back to the country I would most likely choose to live, if not for Costa Rica’s strong pull:
‘My heart beats up here’: Greece’s nomadic herders on life in the hills – a photo essay
For hundreds of years the Vlach herders in Greece and the Balkans have moved livestock to high mountain pastures for the summer months. But their numbers are dwindling as their arduous existence is threatened by soaring costs and a lack of state support
Every spring in the Thessalian plains of central Greece, in the shadow of the mountains, an ancient and sacred migration of humans and goats takes place. Continue reading

Authentica Manuel Antonio
After the opening years helped us strengthen our resolve, 2022 was the year we expanded Authentica beyond the first two locations. I will feature images of the new shop, in Manuel Antonio, in a later post. For now, just a look at the signage art in front of the new shop.

Closing out 2022 with a story that all in our bird-centric community will enjoy, I know from firsthand experience what unexpected encounters with birds can do:

‘Extremely Rare’ Snowy Owl Sighting Transfixes a California Suburb
What brought the owl to the city of Cypress, in Orange County, remains a mystery.
The forbidding frozen wilderness of the high Arctic tundra is the natural home of the snowy owl, a great predator perfectly adapted to hunting its primary food source, lemmings. Continue reading

Carbon Cowboys

Carbon credit brokers are busier than ever, and that is welcome news, but Levi Sucre Romero’s concerns give pause:
Forest Equity: What Indigenous People Want from Carbon Credits
To Indigenous leader Levi Sucre Romero, carbon credit markets have failed to respect Indigenous people and their key role in protecting their lands. In an e360 interview, he talks about how carbon brokers have taken advantage of local communities and why that must change.

In a world where carbon credit markets are taking advantage of Indigenous people and their forests, the United Nation is losing its leadership on combating climate change, says Indigenous leader Levi Sucre Romero.
In an interview with Yale Environment 360, Romero, who is from Costa Rica and is coordinator of the Mesoamerican Alliance of Peoples and Forests, calls out the “carbon cowboys” — the brokers who he says are wrecking efforts to allow Indigenous communities to have ownership of the carbon credits generated on their land, and who, by acting unscrupulously and secretively, are undermining global hopes of using nature to mitigate climate change.

Great EV Expectations

I had no reason to bet against Tesla until now, but I did wonder whether it was good for anyone (other than its shareholders) for that one company to dominate its market over the longer term. Now, happily, it looks like the market will do what we need it to do, which is get robust:
For U.S. Companies, the Race for the New EV Battery Is On
Spurred by federal mandates and incentives, U.S. manufacturers are pushing forward with developing new battery technologies for electric vehicles. The holy grail is a battery that is safer, costs less, provides longer driving range, and doesn’t use imported “conflict” minerals.
Sixteen years have passed since engineer Martin Eberhard unveiled his futuristic custom-designed sports car before a crowd of investors, journalists, and potential buyers in a Santa Monica Airport hangar. Continue reading

An Intelligible Conversation About Artificial Intelligence

We have shared dozens of links to stories about advances in technology–especially those with application to conservation–none has touched on artificial intelligence. During my daily scanning for articles to share in 2022 I have noticed this topic more and more as a source of fear, to the point where I stopped reading them; but today’s is different:
An A.I. Pioneer on What We Should Really Fear
Artificial intelligence stirs our highest ambitions and deepest fears like few other technologies. It’s as if every gleaming and Promethean promise of machines able to perform tasks at speeds and with skills of which we can only dream carries with it a countervailing nightmare of human displacement and obsolescence. But despite recent A.I. breakthroughs in previously human-dominated realms of language and visual art — the prose compositions of the GPT-3 language model and visual creations of the DALL-E 2 system have drawn intense interest — our gravest concerns should probably be tempered. At least that’s according to the computer scientist Yejin Choi, a 2022 recipient of the prestigious MacArthur “genius” grant who has been doing groundbreaking research on developing common sense and ethical reasoning in A.I.

Why Waste Western Water?

The management of water in the western USA has been an occasional topic in these pages and Rachel Monroe adds to our understanding:
The Water Wranglers of the West Are Struggling to Save the Colorado River
Farmers, bureaucrats, and water negotiators converged on Caesars Palace, in Las Vegas, to fight over the future of the drought-stricken Southwest.
In mid-December, I drove to Lake Mead, the nation’s largest reservoir, to see its infamous bathtub ring. The bathtub, in this metaphor, is Lake Mead, on the border between Nevada and Arizona; the ring is a chalk-white coating of minerals that its receding waters have left behind. The Southwest, which includes the Colorado River Basin, has been in a protracted drought since 2000; climate change has made it worse. Continue reading

What To Do With A Tenner

The profound therapeutic benefits of connecting with nature and spending time outside are well known. But in winter? When it’s cold, gloomy and everything looks dead? In fact, especially in the winter, when we are susceptible to fatigue, illness and seasonal low mood. And actually there is plenty of life, beauty and wonder right outside our doors, if we look closely.
Come and take a short walk with me in my nearest wild patch – an urban cemetery, a common environment across the British Isles. Continue reading
