We non-scientists have learned much from the scientists who study climate change, and surprises keep coming, this one from physicist Helen Czerski:

The Planet’s Big Blue Machine: Why the Ocean Engine Matters

The ocean is an enormous engine, turning heat energy into motion, says physicist Helen Czerski. But human activity is threatening that machine — depriving the seas of oxygen, increasing stratification, and potentially changing the currents that influence global weather.

Photographs of Earth taken by astronauts in space more than half a century ago revealed a blue planet dominated by oceans and billowing with clouds. Continue reading →

Water Rights, Heritage & Responsibility

California water has been covered in earlier posts, and it keeps getting more important. Once again, with abundance comes responsibility:

Dear Los Angeles: You’re Drinking Indigenous Water

How LA can localize its water supply and finally do right by the Owens Valley Paiute tribes

In August 2023, a tropical storm bore down upon Southern California for the first time in 84 years. As Hilary’s northward-rolling blanket of rain touched off mudslides from Hollywood to the San Bernardino Mountains, thigh-deep water floated vehicles in the streets of Cathedral City. To the east, 120 miles of Highway 395 were closed due to flooding and rock slides, pinching off the route between the city of Los Angeles and the once-green valley 300 miles away from which it has, for over a century, sourced fresh water.

Really, Cargill?

Cargill has appeared a few times in our pages over the years, not always showing poor stewardship. But today, we have to ask whether they really are trying as diligently as possible to do the right thing. We applaud Beka and her community for this letter, and hope the recipients respond with the sense of responsibility that comes with their wealth:

‘Our world hangs by a thread’: Indigenous activist asks US agri giant to stop destroying Amazon rainforest

Beka Saw Munduruku , 21, traveled 4,000 miles to deliver letter and confront family behind Cargill empire over what she says amounts to a litany of broken promises

A 21-year-old Indigenous activist from a remote Amazonian village will hand deliver a letter to the Cargill-MacMillan dynasty in Minneapolis on Thursday, calling on the billionaire owners of the US’s biggest private company to stop destroying the Amazon rainforest and its people.

With Exceptional Wealth Comes Exceptional Responsibility

Chuck Feeney’s stealthy giving earned him a nickname: “the James Bond of Philanthropy.” Atlantic Philanthropies

May the exceptionally wealthy take note of the example set by Chuck Feeney. Only once have we used the word billionaire in these pages, but a couple of times we pointed to this remarkable man who gave away all his billions while alive, and now that story is complete:

Chuck Feeney’s Legacy Is a Lesson for America’s Billionaires

Yes, the man avoided taxes, but he gave away his fortune, seeking nothing in return.

The selfless billionaire is a rare creature indeed. Chuck Feeney, who died on Monday at the age of 92, was one of them. Continue reading →

Life, Our Understanding, and Nothing

CopperMines-118

The desert isn’t usually known for its unrivaled ability to support life, and for good reason. Deserts are, if not quite hostile, harsh environments, and the very air can suck the life essence – valuable water, out of unprepared visitors. Fortunately, the natives have had all the time in the world to thicken their skin, grow water bladders in their feet, shrink their stomata, or whatever appropriate organ addition/subtraction/modification may describe their gradual adaptation to a dangerously dry environment. In the above photograph, a spider (from a long line of spiders that no doubt were faced with the very same decisions and dangers as it was) has industriously coated all the available branch space of a small shrub. How, or why, I don’t know. What matters is that one organism – the spider in question, was drawn to this particular shrub, of all the similar shrubs in the valley. Was it drawn to the beauty of the tree? Did the spider somehow know there would be a hearty meal within? Was it merely the first vertical object to come within view? Do electrical impulses travel through the nervous system of the species to which this particular spider belongs at a certain time of day telling it to simply lay web until the nearest object is covered?

How can we find out? How will we know if what we find out is true? Why do we care?

These are big questions.

Where Your Seafood Comes From, And How

Ian Urbina has chronicled this topic in the past, and the fishing crimes on the high seas have not abated, to say the least:

BEHIND THE SEAFOOD YOU EAT

China has invested heavily in an armada of far-flung fishing vessels, in part to extend its global influence. This maritime expansion has come at grave human cost.

DANIEL ARITONANG GRADUATED from high school in May, 2018, hoping to find a job. Short and lithe, he lived in the coastal village of Batu Lungun, Indonesia, where his father owned an auto shop. Aritonang spent his free time rebuilding engines in the shop, occasionally sneaking away to drag-race his blue Yamaha motorcycle on the village’s back roads. Continue reading →

Stories from the Field: Spoon-billed Sandpiper

In my previous post I’d written about birding with Clement Francis and how educational he was in so many ways – sparking my interest in birding, my abilities as a bird photographer, and not least, my understanding of the challenges that birds and other wildlife suffer in the face of climate change and human related habit destruction. The story of the Spoon-billed Sandpiper impacted me in a huge way.

This tiny bird travels between the Arctic Tundra and the South Asiatic regions. While they breed in the tundra, they migrate southwards during winters in a migratory route of 8000 kilometres. Just 200 pairs of this birds existed back then. Now due to human intervention and the implementation of captive breeding programmes, the population are reaching to a decent number.

The International Union for Conservation of Nature (IUCN)  has listed the Spoon-billed Sandpiper under the “critically endangered” species. During one of our trips Clement showed me the picture of the bird in its breeding plumage that was shot in Siberia. From that moment on my mind was set on seeing the bird. It may appear like an exaggeration, but the bird appeared in my dreams quite often and the desire to see it for myself grew stronger every day. At the time of our trip the bird was in migration to a small patch in the Sunderbans of Bangladesh,  but the numbers there were decreasing, and their path seemed to be shifting toward stopovers in Thailand instead.

Rhodope, Bulgaria & Rodopi, Greece

I first heard of this ecosystem nearly a decade ago, not realizing then that it spreads into northeastern Greece. We are in this ecosystem currently, on the Greek side, and yesterday visited the Rodopi Mountain Range National Park. In the photo above you can see Milo, in a location not far from that national park, with one of his favorite types of organism. I thought to revisit the Rewilding Europe website just now, and am happy to link again to their work:

Rhodope Mountains is the most important breeding area for griffon vultures in Bulgaria. The whole region is also a stronghold  for wolf and jackal.

The Rhodope mountains hold a captivating array of of flora and fauna and is a stronghold of vultures in south-eastern Europe. It’s the only breeding spot in Bulgaria for griffon vultures and an important site for the globally threatened Egyptian vulture on the Balkan Peninsula. Additionally, rare cinereous vultures can be spotted soaring above. Among the dozens of other raptor species Eastern imperial eagle, Saker falcon, Levant sparrowhawk, Peregrine falcon and several other eagles can be mentioned.

The whole region is also a stronghold within Bulgaria for wolf and jackal. In recent years, brown bears have begun naturally recolonizing the Rhodopes, and the possibility of bear-watching is emerging in the landscape, particularly in the western part of the mountains.

Because of its location at the crossroads between the European and Asian continent, the impact of the Mediterranean, its pristine landscapes and the variety of habitats here in combination with the relatively small human disturbance, the Rhodope Mountains have a huge variety in species and habitats, and have become one of the bird watching hotspots in Europe.

 

Alternative Land Improvement

Lawns are not the only option for yards, and sometimes removing grass is the first step to improvement. Jessica Andreone’s story, on the Modern Farmer website (too long since our last link to that great resource), about alternative land improvement resonates with my own project over the last five years:

Crop plants growth is stunted from compacted soil.

We Bought a Home with a Sterile Suburban Yard. Our Journey To Bring Life Back is Just Beginning

When we bought our first home, we had grand plans to create a productive and pollinator-friendly oasis. Then the reality of poor soils and extreme weather hit.

My husband and I bought our first home in a small West Virginia town in January 2023. The bright green dwelling sits in the middle of a dead-end street where retirees claim most homes as the original dwellers. From 1978 until now, our house had only one homeowner. So, for the past 45 years, the yard has been a neatly mowed lawn with a single tulip tree. Continue reading →

Beware the backlash, but move the ball forward:

Green protectionism comes with big risks

Some analysts worry that new laws could slow the green transition

Politicians think they have cracked it. Continue reading →
