One important takeaway from this article, if you're a gardener, is that there's a corresponding Heat Zone Map put together by the American Horticultural Society that isn't widely known.
With tools like the USDA plant hardiness map, we typically only consider low winter temperatures as the primary metric by which we determine
They're trying to implement this info more in the Hardiness Zone map, but trying to account for too many factors in a single metric runs the risk of muddling the metric, so it's worth considering them separately.
Farmers Fencing Off Streams Has Restored Over 1000 Miles of Waterway in Oklahoma
Image and text from this article in the New York Times:
Oklahoma has been exemplary in cleaning up its streams, by some measures more than any other state. A big part of the solution was simple: Give cows clean drinking water and keep them out of streams. When one farmer tried it, he quickly saw results. His veterinarian bills went down and wildlife returned to the area.
[...]
For Mr. Victor, the decision to fence his cattle off from the waterway wasn’t easy. The creek was why his great-grandmother, who was Cherokee, especially prized the land. The parcel was allotted to her in 1891 through the Dawes Act, which allowed the federal government to break up tribal land. The waterway gave the family’s cattle a place where they could drink and cool off.
“I’m sure at the coffee shop, they were all laughing at me,” Mr. Victor, 68, said.
But even though it’s my land, it’s not really my land. I’m just a person here with it at this time, and I carry that big responsibility.
The benefits of a healthier waterway exceeded his hopes. Mr. Victor thought that the land around the creek might regenerate in five years, perhaps 10. But within just a couple of years, the banks were transformed into verdant corridors of grasses and shrubs. Wildlife appeared, including white-tailed deer, bobcats, coyotes and bald eagles that return each year to a sprawling nest to rear their young.
I think we lose a lot when we envision conservation or environmental protection as something that only folks in left-leaning states or communities care about. Climate change and environmentalism didn't use to be partisan issues. This work is for everyone and there are allies in more places than a lot of people would expect.

From the article:
New research from Colorado State University and Cornell University shows that the presence of solar panels in Colorado’s grasslands may reduce water stress, improve soil moisture levels and — particularly during dry years — increase plant growth by about 20% or more compared to open fields.
One of the biggest downsides to renewable energy sources is that they usually take up more physical space--and therefore more habitat--than fossil fuels. However, there is increasing evidence that combining solar panels with certain food crops or types of habitat can actually be beneficial to both!
This study is particularly heartening because it implies that solar panels may help certain ecosystems weather the increased droughts brought on by climate change.
The slimy strings from okra and the gel from fenugreek seeds can trap microplastics better than the slightly-toxic synthetic polymer in use.
"The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer.
Texas researchers proposed in 2022 using these sticky natural polymers to clean up water. Now, they’ve found that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics from ocean water, freshwater, and groundwater.
With funding from the U.S. Department of Energy, Rajani Srinivasan and colleagues at Tarleton State University found that the plant-based polymers from okra, fenugreek, and tamarind stick to microplastics, clumping together and sinking for easy separation from water.
In this next stage of the research, they have optimized the process for okra and fenugreek extracts and tested results in a variety of types of water.
To extract the sticky plant polymers, the team soaked sliced okra pods and blended fenugreek seeds in separate containers of water overnight. Then, researchers removed the dissolved extracts from each solution and dried them into powders.
Analyses published in the American Chemical Society journal showed that the powdered extracts contained polysaccharides, which are natural polymers. Initial tests in pure water spiked with microplastics showed that:
One gram of either powder in a quart (one liter) of water trapped microplastics the most effectively.
Dried okra and fenugreek extracts removed 67% and 93%, respectively, of the plastic in an hour.
A mixture of equal parts okra and fenugreek powder reached maximum removal efficiency (70%) within 30 minutes.
The natural polymers performed significantly better than the synthetic, commercially available polyacrylamide polymer used in wastewater treatment.
Then the researchers tested the plant extracts on real microplastic-polluted water. They collected samples from waterbodies around Texas and brought them to the lab. The plant extract removal efficiency changed depending on the original water source.
Okra worked best in ocean water (80%), fenugreek in groundwater (80-90%), and the 1:1 combination of okra and fenugreek in freshwater (77%).
The researchers hypothesize that the natural polymers had different efficiencies because each water sample had different types, sizes and shapes of microplastics.
Polyacrylamide, which is currently used to remove contaminants during wastewater treatment, has low toxicity, but its precursor acrylamide is considered toxic. Okra and fenugreek extracts could serve as biodegradable and nontoxic alternatives.
“Utilizing these plant-based extracts in water treatment will remove microplastics and other pollutants without introducing additional toxic substances to the treated water,” said Srinivasan in a media release, “thus reducing long-term health risks to the population.”
She had previously studied the use of food-grade plant extracts as non-toxic flocculants to remove textile-based pollutants from wastewater and thought, ‘Why not try microplastics?’"

This underground coal seam fire had been smoldering since possibly as early as the late 1800s, but was finally fully extinguished thanks to recent excavation and restoration of the site. The surrounding area can also now return to vegetated wildlife habitat, as before the fire was extinguished the vegetation had to be severely cut back to reduce wildfire risk.
Coal seam fires contribute to climate change by releasing methane and carbon dioxide, and they can potentially spark forest fires which are a particularly high risk in dry, fire-prone climates like much of Colorado.
From the article:
“We all remember so well the devastation of the Marshall Fire not too long ago, right here in our community,” said U.S. Representative Joe Neguse during a press conference.
“And to know that this particular threat will now be resolved long into the future is an important preventative step that I think the state of Colorado and our local government partners should be deeply proud of.”
as people are gearing up for gardening and might be doing it for the first time, psa that if you're filling up raised beds of any significant size, it's almost definitely going to be cheaper to buy soil in bulk from a nursery/landscaping place than to buy it bag by bag from a store.
learn from my mistakes and inspect the soil first (mine has more clay and small stones than i would prefer, but it's still fine), but i paid like. a third of what i would have had to if i had bought it bag by bag from a store.
Guys they reintroduced Galapagos tortoises to espanola island and they’ve essentially terraformed their environment, knocking over invasive plants so that endangered albatrosses (who need space to take off using the ground as a runway) have returned and established nests!
A decades-long project to reintroduce Galapagos giant tortoises is changing the face of the island of Española.
"In the late 19th century, whalers, settlers, and pirates changed the ecology of the Galapagos Islands by poaching some native species—like Galapagos giant tortoises—and introducing others, like goats and rats. The latter species became pests and severely destabilized the island ecosystems. Goats overgrazed the fruits and plants the tortoises ate while rats preyed on their eggs. Over time, the tortoise population plummeted. On Española, an island in the southeast of the archipelago, the tortoise count fell from over 10,000 to just 14. Along the way, with goats eating all the plants they could, Española—once akin to a savanna—turned barren.
A century later, conservationists set out to restore the Galapagos giant tortoise on Española—and the island ecosystem. They began eradicating the introduced species and capturing Española’s remaining tortoises and breeding them in captivity. With the goats wiped out and the tortoises in cages, the ecosystem transformed once again. This time, the overgrazed terrain became overgrown with densely packed trees and woody bushes. Española’s full recovery to its savanna-like state would have to wait for the tortoises’ return.
From the time those 14 tortoises were taken into captivity between 1963 and 1974 until they were finally released in 2020, conservationists with the NGO Galápagos Conservancy and the Galapagos National Park Directorate reintroduced nearly 2,000 captive-bred Galapagos giant tortoises to Española. Since then, the tortoises have continued to breed in the wild, causing the population to blossom to an estimated 3,000. They’ve also seen the ecology of Española transform once more as the tortoises are reducing the extent of woody plants, expanding the grasslands, and spreading the seeds of a key species.
Not only that, but the tortoises’ return has also helped the critically endangered waved albatross—a species that breeds exclusively on Española. During the island’s woody era, Maud Quinzin, a conservation geneticist who has previously worked with Galapagos tortoises, says that people had to repeatedly clear the areas the seabirds use as runways to take off and land. Now, if the landing strips are getting overgrown, they’ll move tortoises into the area to take care of it for them.
The secret to this success is that—much like beavers, brown bears, and elephants—giant tortoises are ecological architects. As they browse, poop, and plod about, they alter the landscape. They trample young trees and bushes before they can grow big enough to block the albatrosses’ way. The giant tortoises likewise have a potent impact on the giant species of prickly pear cactuses that call Española home—one of the tortoises’ favorite foods and an essential resource for the island’s other inhabitants.
When the tortoises graze the cactus’s fallen leaves, they prevent the paddle-shaped pads from taking root and competing with their parents. And, after they eat the cactus’s fruit, they drop the seeds across the island in balls of dung that offer a protective shell of fertilizer...
As few as one or two tortoises per hectare [about 2.5 acres], the scientists write, is enough to trigger a shift in the landscape."
I hope everyone understands, when I say “most endangered habitat on earth”, I mean temperate grasslands.
They’re more endangered than tropical rainforests, coral reefs, the arctic tundra, all of those go-to environments that get more of the spotlight.
Where I live, maybe 25% of the prairie remains in a natural state and that number is dropping. Even these fragments are mostly missing the keystone species that maintain their health, like bison, wolves, and prairie dogs. I know this is the case for other grasslands like the pampas and steppe as well. Vast lands empty of many species that used to call them home.
If you live on temperate grasslands, hold onto them tight, because they’ve been exploited like no other land and most people don’t even know how far the devastation goes.
please please pleaseeee listen to this post and learn the value of temperate grasslands. it makes me very sad that not only have these landscapes been destroyed by colonizers, but even most of the people who live there now don’t see their value. when i say i love midwestern landscapes, people call me crazy just because they’ve never seen the beauty of the tallgrass prairie :(
With “green corridors” that mimic the natural forest, the Colombian city is driving down temperatures -- and could become five degrees coole
"With “green corridors” that mimic the natural forest, the Colombian city is driving down temperatures — and could become five degrees cooler over the next few decades.
In the face of a rapidly heating planet, the City of Eternal Spring — nicknamed so thanks to its year-round temperate climate — has found a way to keep its cool.
Previously, Medellín had undergone years of rapid urban expansion, which led to a severe urban heat island effect — raising temperatures in the city to significantly higher than in the surrounding suburban and rural areas. Roads and other concrete infrastructure absorb and maintain the sun’s heat for much longer than green infrastructure.
“Medellín grew at the expense of green spaces and vegetation,” says Pilar Vargas, a forest engineer working for City Hall. “We built and built and built. There wasn’t a lot of thought about the impact on the climate. It became obvious that had to change.”
Efforts began in 2016 under Medellín’s then mayor, Federico Gutiérrez (who, after completing one term in 2019, was re-elected at the end of 2023). The city launched a new approach to its urban development — one that focused on people and plants.
The $16.3 million initiative led to the creation of 30 Green Corridors along the city’s roads and waterways, improving or producing more than 70 hectares of green space, which includes 20 kilometers of shaded routes with cycle lanes and pedestrian paths.
These plant and tree-filled spaces — which connect all sorts of green areas such as the curb strips, squares, parks, vertical gardens, sidewalks, and even some of the seven hills that surround the city — produce fresh, cooling air in the face of urban heat. The corridors are also designed to mimic a natural forest with levels of low, medium and high plants, including native and tropical plants, bamboo grasses and palm trees.
Heat-trapping infrastructure like metro stations and bridges has also been greened as part of the project and government buildings have been adorned with green roofs and vertical gardens to beat the heat. The first of those was installed at Medellín’s City Hall, where nearly 100,000 plants and 12 species span the 1,810 square meter surface.
“It’s like urban acupuncture,” says Paula Zapata, advisor for Medellín at C40 Cities, a global network of about 100 of the world’s leading mayors. “The city is making these small interventions that together act to make a big impact.”
At the launch of the project, 120,000 individual plants and 12,500 trees were added to roads and parks across the city. By 2021, the figure had reached 2.5 million plants and 880,000 trees. Each has been carefully chosen to maximize their impact.
“The technical team thought a lot about the species used. They selected endemic ones that have a functional use,” explains Zapata.
The 72 species of plants and trees selected provide food for wildlife, help biodiversity to spread and fight air pollution. A study, for example, identified Mangifera indica as the best among six plant species found in Medellín at absorbing PM2.5 pollution — particulate matter that can cause asthma, bronchitis and heart disease — and surviving in polluted areas due to its “biochemical and biological mechanisms.”
And the urban planting continues to this day.
The groundwork is carried out by 150 citizen-gardeners like Pineda, who come from disadvantaged and minority backgrounds, with the support of 15 specialized forest engineers. Pineda is now the leader of a team of seven other gardeners who attend to corridors all across the city, shifting depending on the current priorities...
“I’m completely in favor of the corridors,” says [Victoria Perez, another citizen-gardener], who grew up in a poor suburb in the city of 2.5 million people. “It really improves the quality of life here.”
Wilmar Jesus, a 48-year-old Afro-Colombian farmer on his first day of the job, is pleased about the project’s possibilities for his own future. “I want to learn more and become better,” he says. “This gives me the opportunity to advance myself.”
The project’s wider impacts are like a breath of fresh air. Medellín’s temperatures fell by 2°C in the first three years of the program, and officials expect a further decrease of 4 to 5C over the next few decades, even taking into account climate change. In turn, City Hall says this will minimize the need for energy-intensive air conditioning...
In addition, the project has had a significant impact on air pollution. Between 2016 and 2019, the level of PM2.5 fell significantly, and in turn the city’s morbidity rate from acute respiratory infections decreased from 159.8 to 95.3 per 1,000 people [Note: That means the city's rate of people getting sick with lung/throat/respiratory infections.]
There’s also been a 34.6 percent rise in cycling in the city, likely due to the new bike paths built for the project, and biodiversity studies show that wildlife is coming back — one sample of five Green Corridors identified 30 different species of butterfly.
Other cities are already taking note. Bogotá and Barranquilla have adopted similar plans, among other Colombian cities, and last year São Paulo, Brazil, the largest city in South America, began expanding its corridors after launching them in 2022.
“For sure, Green Corridors could work in many other places,” says Zapata."
The thing about Cottagecore is that is a fetishized aesthetic of country life, divorced from labor and idealized by a primarily urban audience with a backward looking ethos of tradition. They are not prepared for the stresses of a rural life: farming; harvesting; tapping pumpkins to ensure none of them have been replaced with flesh; losing out on income by having to use one of your pigs in a blood sacrifice to paint protective sigils over your doors and windows; checking cracks and chimneys for the flesh-vines of the Pumpkin Lord; having to decide, before the Growth is complete, whether that's really your tradwife or an amassment of vines, leaves, and blood in the shape of your tradwife; ignoring their desperate pleas that "I'm me! No! No!" as you burn them alive, realizing too late you picked wrong; and the exploitative corporate nature of commercial farming in 2024. All seen through a deeply colonial lens, of course
hey, how do you cope with people saying we only have a small amount of time left to stop the worst effects of climate change? no matter how hopeful and ok i am, that always sends me back into a spiral :(
A few different ways
1. The biggest one is that I do math. Because renewable energy is growing exponentially
Up until basically 2021 to now, all of the climate change models were based on the idea that our ability to handle climate change will grow linearly. But that's wrong: it's growing exponentially, most of all in the green energy sector. And we're finally starting to see proof of this - and that it's going to keep going.
And many types of climate change mitigation serve as multipliers for other types. Like building a big combo in a video game.
Change has been rapidly accelerating and I genuinely believe that it's going to happen much faster than anyone is currently predicting
2. A lot of the most exciting and groundbreaking things happening around climate change are happening in developing nations, so they're not on most people's radars.
But they will expand, as developing nations are widely undergoing a massive boom in infrastructure, development, and quality of life - and as they collaborate and communicate with each other in doing so
3. Every country, state, city, province, town, nonprofit, community, and movement is basically its own test case
We're going to figure out the best ways to handle things in a remarkably quick amount of time, because everyone is trying out solutions at once. Instead of doing 100 different studies on solutions in order, we get try out 100 (more like 10,000) different versions of different solutions simultaneously, and then figure out which ones worked best and why. The spread of solutions becomes infinitely faster, especially as more and more of the world gets access to the internet and other key infrastructure
4. There's a very real chance that many of the impacts of climate change will be reversible
Yeah, you read that right.
Will it take a while? Yes. But we're mostly talking a few decades to a few centuries, which is NOTHING in geological history terms.
We have more proof than ever of just how resilient nature is. Major rivers are being restored from dried up or dead to thriving ecosystems in under a decade. Life bounces back so fast when we let it.
I know there's a lot of skepticism about carbon capture and carbon removal. That's reasonable, some of those projects are definitely bs (mostly the ones run by gas companies, involving carbon credits, and/or trying to pump CO2 thousands of feet underground)
But there's very real potential for carbon removal through restoring ecosystems and regenerative agriculture
The research into carbon removal has also just exploded in the past three years, so there are almost certainly more and better technologies to come
There's also some promising developments in industrial carbon removal, especially this process of harvesting atmospheric CO2 and other air pollution to make baking soda and other industrially useful chemicals
