Seagrasses, mangrove forests, and coastal wetlands store vast amounts of carbon, and their preservation and restoration hold great potential to bank CO2 and keep it out of the atmosphere. But can the blue carbon market avoid the pitfalls that have plagued land-based programs?
Off the shores of Virginia, vast meadows of seagrass sway in the shallow waters. Over the past two decades, conservation scientists have spread more than 70 million seeds in the bays there, restoring 3,600 hectares (9,000 acres) of an ecosystem devastated by disease in the 1930s. The work has brought back eelgrass (Zostera marina) — a keystone species that supports crustaceans, fish, and scallops, and is now absorbing the equivalent of nearly half a metric ton of CO2 per hectare per year.

Reducing synthetic nitrogen in farming, by letting legumes do more nitrogen-fixing in the soil, has plenty of other benefits:
Plant more bean-like crops in Europe and consider ‘healthy diet transition’ to beat climate crisis, say scientists
Adding the likes of peas, lentils, beans, and chickpeas to your diet, and farming more of them, could result in more nutritious and effective food production with large environmental benefits, scientists have found. Continue reading
We have committed to planting trees. And we know that getting to a trillion trees planted is not going to be easy. But the effort has obvious and less obvious upsides. Every great idea also has its downside(s) and challenges to surmount, even planting trees:
High-profile programs aimed at planting billions of trees are being launched worldwide. But a growing number of scientists are warning that these massive projects can wreck natural ecosystems, dry up water supplies, damage agriculture, and push people off their land.
In late January, the multibillionaire Elon Musk took to Twitter and abruptly announced, “Am donating $100M towards a prize for best carbon capture technology”. This triggered a deluge of sarcasm across the platform: “You mean, like, trees?” “I planted a tree, do I win?” Continue reading
In Washington, D.C. the cherry blossoms came early this year. Plenty was said, including on Texas Public Radio, about the implications related to climate change. Elizabeth Kolbert has this to say, pivoting from cherry blossoms to both environmental and economic policies in the USA:
The Administration has an ambitious vision for combatting global warming, but it’s only a start.
The first known reference to Japan’s cherry blossoms comes from the country’s oldest surviving text, the Kojiki, completed in 712. Japan was trying to shrug off the influence of its more powerful neighbor, China, and cherry blossoms became a symbol of Japanese identity, in contrast to the plum blossoms of the Chinese. By the early ninth century, the practice of cherry-blossom viewing had become so well established that the date of the peak bloom appeared in Japanese poems and other literary works. Continue reading
Thanks to Scotland, for the ambition and demonstration; and to the BBC for reporting this:
Scotland has narrowly missed a target to generate the equivalent of 100% of its electricity demand from renewables in 2020.
New figures reveal it reached 97.4% from renewable sources.
This target was set in 2011, when renewable technologies generated just 37% of national demand. Continue reading
Yesterday’s post was about a book that argues we must change the way we source food. Water use is a parallel topic, of equal importance, and today National Public Radio (USA) presents an investigative report about Louisiana’s challenges related to water, and changes that must be made:
Louisiana is known for its losing battle against rising seas and increasingly frequent floods. It can sometimes seem like the state has too much water. But the aquifers deep beneath its swampy landscape face a critical shortage.
Groundwater levels in and around Louisiana are falling faster than almost anywhere else in the country, according to U.S. Geological Survey data. An analysis by the Investigative Reporting Workshop and WWNO/WRKF traced the problem to decades of overuse, unregulated pumping by industries and agriculture, and scant oversight or action from legislative committees rife with conflicts of interest. Continue reading
One of the many things that humans have been doing for a long time that are going to have to change:
Dragging heavy nets across seabed disturbs marine sediments, world’s largest carbon sink, scientists report
Fishing boats that trawl the ocean floor release as much carbon dioxide as the entire aviation industry, according to a groundbreaking study.
Bottom trawling, a widespread practice in which heavy nets are dragged along the seabed, pumps out 1 gigaton of carbon every year, says the study written by 26 marine biologists, climate experts and economists and published in Nature on Wednesday. Continue reading
John Paul MacDuffie and Sarah E. Light, both professors at the Wharton School of Business at the University of Pennsylvania, have published an article on Yale E360 highlighting the improving potential for electric vehicles to dominate the USA market sooner than previously expected:
Driven by GM, Tesla, and the Biden administration, the U.S. is now poised to press ahead in the transformation to electric vehicles. Big challenges still loom, but technological advances, government support, and growing consumer appeal will drive the inevitable switch to EVs.
Last month’s failure of the Texas electric grid, coming just weeks after General Motors’ pledge to make only electric vehicles by 2035, highlights the daunting task the United States faces as it takes the first steps toward weaning its economy off fossil fuels. Continue reading
Indigenous communities might seem obvious stakeholders in the protection of wilderness areas, but it does not always, or even often, play out that way. Graham Lee Brewer, a reporter for Audubon Magazine, has this to say about changes in the works:
An emerging effort to protect 30 percent of the country’s land and water is an opportunity to strengthen tribal sovereignty and heed Indigenous ecological knowledge, experts say.
For nearly four decades the Blackfeet Nation has fought off attempts to drill for oil and gas in Montana’s Badger-Two Medicine area. Nestled in a national forest beside Glacier National Park, the region’s sweeping valleys, rivers, and wetlands—almost entirely unmarred by roads—form the setting of the Blackfeet creation story and host tribal ceremonies today. Continue reading
The fact that we’re a late to highlight this new addition doesn’t lessen our enthusiasm for the fact. The United States National Park Service and the those who created it, and continue to fight for it, are heroes in our eyes. It’s an especially strong breath of fresh air when this new administration moves immediately to promote this “great idea” rather than diminish it.
The New River Gorge in West Virginia got the federal government’s highest protection, thanks, in part, to the latest pandemic relief bill.
As Americans continue to weather the pandemic, the $2.3 trillion coronavirus relief and spending bill passed by the federal government in December brought an unexpected and lasting gift: a new national park.
The 5,593-page spending package included a raft of provisions authorizing little-known projects — the construction of the Teddy Roosevelt Presidential Library in North Dakota, for one — and giving lawmakers a chance to advance a variety of long-delayed initiatives. Among them was the elevation of the New River Gorge, in southern West Virginia, to the status of Yellowstone, Yosemite and the country’s other most renowned outdoor spaces. The designation of the area — roughly 72,000 acres of land flanking 53 miles of the gorge — as a national park and preserve creates the 63rd national park in the United States and completes a multigenerational effort, started in the mid-twentieth century, to transform a tired industrial area into a national landmark.
“Towards the end of this year, with these big bills coming down, I decided to strike,” said Shelley Moore Capito, a Republican and the state’s junior senator, who, along with Senator Joe Manchin III, a Democrat, introduced the New River Gorge legislation in 2019.
“This was the right opportunity,” she said. Continue reading
Thanks to Yale e360:
After years of false starts, offshore wind is poised to take off along the East Coast. Commitments by states to purchase renewable power, support from the Biden administration, and billions in new investment are all contributing to the emergence of this fledgling industry.
About 60 miles east of New York’s Montauk Point, a 128,000-acre expanse of the Atlantic Ocean is expected to produce enough electricity to power around 850,000 homes when it’s populated with wind turbines and connected to the onshore grid in the next few years.
Fifteen miles off Atlantic City, New Jersey, another windy swath of ocean is due to start generating enough power for some 500,000 homes when a forest of 850-foot-high turbines start turning there in 2024.
I am responsible for managing a small enterprise. As we expanded into ecommerce some months ago, I looked into the advantages offered by Amazon’s fulfillment services. But the disadvantages, which I have been reading about and posting about here for some years outweighed the advantages.
Having just read this op-ed on the same topic, I am more convinced than ever of the dangers Amazon poses to companies like ours. Maureen Tkacik, a senior fellow at the American Economic Liberties Project, does an an additional service by highlighting the efforts of Congresswoman Lucy McBath (who Amie had the good fortune to be able to campaign for and who our family voted for when we resided in her district during her first campaign) to hold the company accountable:
The Amazon founder prepares to step back just as Washington turns up the heat on the mega-retailer and cloud company.
If I had to guess who inspired Amazon’s founder, Jeff Bezos, to kick himself upstairs and appoint Andy Jassy, a deputy, as his successor as chief executive, I might wager that at least part of the blame can be laid on Lucy McBath, the freshman Georgia congresswoman, and her understated grilling of one of the world’s richest men at a July hearing held by the House antitrust subcommittee.

Bill McKibben’s weekly newsletter, as usual, has gems worthy of attention, and the fate of the Yaak Valley qualifies:
The blizzard of federal climate initiatives last week (a blizzard that might help allow actual blizzards to persist into the future) is without precedent. For the first time in the thirty-plus years of our awareness of the climate crisis, Washington roused itself to urgent action; veterans of the cautious Obama Administration—the domestic climate adviser Gina McCarthy and the global climate czar John Kerry chief among them—were suddenly going for broke. In fact, only one branch of the Cabinet seemed conspicuous by its muted presence: the Department of Agriculture, which has responsibility for the nation’s farms and for many of its forests—that is, for the natural features that will either speed or slow the flow of carbon into the atmosphere. Continue reading
Thanks to an inter-party agreement, the clean energy hub in the North Sea is set to be the largest construction project in Danish history
Denmark’s government has agreed to take a majority stake in a £25bn artificial “energy island”, which is to be built 50 miles (80km) offshore, in the middle of the North Sea.
The island to the west of the Jutland peninsula will initially have an area of 120,000 sq metres – the size of 18 football pitches – and in its first phase will be able to provide 3m households with green energy. Continue reading
Hats off to the UK for commissioning the study, and to Professor Dasgupta for completing it. Sometimes a profession, like economics, takes time to catch up with the real world. Better late than never, like the guide to investing in nature, we are happy to see academia putting rigor into the analysis of how valuable nature is. Seemed obvious, even without these new studies, but this is what it takes to counter the disinformation promoted by extraction-intensive industries and their investors:
The Dasgupta Review is an independent, global review on the Economics of Biodiversity led by Professor Sir Partha Dasgupta (Frank Ramsey Professor Emeritus, University of Cambridge). The Review was commissioned in 2019 by HM Treasury and has been supported by an Advisory Panel drawn from public policy, science, economics, finance and business. Continue reading
Phoebe Weston is back in our pages with a story about the importance of a seemingly prosaic part of the old UK landscape–hedgerows.
She covers their prospective role in meeting net-zero targets and the video above is an excellent primer on that. The details in her article below about Rob Wolton’s investigation of his own hedgerow is fascinating. I am interested in the topic as much for the biodiversity implications as I consider whether my berms should all remain berms, or if some portion should become hedgerow:
They store carbon and are havens for wildlife – it’s no wonder experts are calling for Britain’s hedge network to be extended
One New Year’s Day, ecologist Rob Wolton came up with an unusual resolution – to spend the next 12 months studying a hedge 40 metres from his house in the middle of Devon. He wanted to make a list of every plant, animal and fungus that used it. Why? Because a wildlife-enthusiast friend challenged him to do it during a long car journey.
“I thought it would take a year, but at the end of the first one Continue reading
It remains to be seen whether Joe Biden’s sweeping climate directives can make a meaningful difference, but a critical threshold has been crossed.
Nine years ago, Senator Sheldon Whitehouse had a sign made up that showed a photograph of the Earth as seen from space. “time to wake up,” it urged, in large, unevenly spaced letters. Every week that the Senate was in session, Whitehouse, a Democrat from Rhode Island, would tote the sign to the chamber, set it on an easel, and, before a hundred chairs—most of them empty—deliver a speech. Though the details changed, the subject of the speech remained the same. Continue reading
Catchy. Effective? We will see. Thanks to the Guardian for this view on a UK initiative to reducing food waste at home:
National government-backed initiative will replace ‘use by’ with ‘best before’ and urge people to judge for themselves
Worried about whether the yoghurt, milk and cheese sitting in your fridge is still safe to eat? Rather than rely on the misleading “best by” date stamped on the side, perhaps its time to “sniff and taste” your staple foods. Continue reading
Last week I walked with my grand-daughter among these almendro trees. Amie and I helped plant these when they were foot-high saplings in 2019, and we tagged one with our grand-daughter’s name. The trees, now 3+ feet high, are part of a coastal reforestation scheme; their beneficence includes producing fruits favored by scarlet macaws.
Everyone loves scarlet macaws. And these trees grow faster than our grand-daughter, giving constant positive feedback. When you have an opportunity to do something like plant a tree, or any other restorative act, first things first: do it. Thanks to Bill McKibben for pointing this out as one of the highlights of yesterday’s change of scenery in Washington, D.C.:
In his first hours in office, Joe Biden has settled—almost certainly, once and for all—one of the greatest environmental battles this country has seen. He has cancelled the permit allowing the Keystone XL pipeline to cross the border from Canada into the United States, and the story behind that victory illustrates a lot about where we stand in the push for a fair and working planet. Continue reading
Thanks to the BBC for this feature story:
Bicycle share schemes have had huge success in some cities and flopped spectacularly in others – what is it that makes or breaks a bike share?
A set of iconic photos from 2017 show brightly coloured fields which, at first glance, look like meadows filled with flowers in full bloom. It takes a while to register that the images aren’t of verdant fields, but ones filled with bicycles: hundreds and thousands of two-wheelers, stacked end-to-end in what came to be called China’s bicycle graveyards.
