"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."

In 2020, for the first time since being laid in 1772, a section of a King’s College lawn the size of just half a football pitch was not mown. Instead, it was transformed into a colourful wildflower meadow filled with poppies, cornflowers and oxeye daisies.

[Researcher Dr Cicely Marshall] found that as well as being a glorious sight, the meadow had boosted biodiversity and was more resilient than lawn to our changing climate. The results are published today in the journal Ecological Solutions and Evidence. Despite its size, the wildflower meadow supported three times more species of plants, spiders and bugs than the remaining lawn - including 14 species with conservation designations, compared with six in the lawn.

The meadow was found to have another climate benefit: it reflected 25% more sunlight than the lawn, helping to counteract what’s known as the ‘urban heat island’ effect. Cities tend to heat up more than rural areas, so reflecting more sunlight can have a cooling effect - useful in our increasingly hot summers. “Cambridge has become more prone to drought, and last summer most of the College’s fine lawns died. It’s really expensive to maintain these lawns, which have to be re-sown if they die off. But the meadow just looked after itself,” says Marshall.

"Starting this month [June 2024], thousands of young people will begin doing climate-related work around the West as part of a new service-based federal jobs program, the American Climate Corps, or ACC. The jobs they do will vary, from wildland firefighters and “lawn busters” to urban farm fellows and traditional ecological knowledge stewards. Some will work on food security or energy conservation in cities, while others will tackle invasive species and stream restoration on public land. 

The Climate Corps was modeled on Franklin D. Roosevelt’s Civilian Conservation Corps, with the goal of eventually creating tens of thousands of jobs while simultaneously addressing the impacts of climate change. 

Applications were released on Earth Day, and Maggie Thomas, President Joe Biden’s special assistant on climate, told High Country News that the program’s website has already had hundreds of thousands of views. Since its launch, nearly 250 jobs across the West have been posted, accounting for more than half of all the listed ACC positions. 

“Obviously, the West is facing tremendous impacts of climate change,” Thomas said. “It’s changing faster than many other parts of the country. If you look at wildfire, if you look at extreme heat, there are so many impacts. I think that there’s a huge role for the American Climate Corps to be tackling those crises.”  

Most of the current positions are staffed through state or nonprofit entities, such as the Montana Conservation Corps or Great Basin Institute, many of which work in partnership with federal agencies that manage public lands across the West. In New Mexico, for example, members of Conservation Legacy’s Ecological Monitoring Crew will help the Bureau of Land Management collect soil and vegetation data. In Oregon, young people will join the U.S. Department of Agriculture, working in firefighting, fuel reduction and timber management in national forests. 

New jobs are being added regularly. Deadlines for summer positions have largely passed, but new postings for hundreds more positions are due later this year or on a rolling basis, such as the Working Lands Program, which is focused on “climate-smart agriculture.”  ...

On the ACC website, applicants can sort jobs by state, work environment and focus area, such as “Indigenous knowledge reclamation” or “food waste reduction.” Job descriptions include an hourly pay equivalent — some corps jobs pay weekly or term-based stipends instead of an hourly wage — and benefits. The site is fairly user-friendly, in part owing to suggestions made by the young people who participated in the ACC listening sessions earlier this year...

The sessions helped determine other priorities as well, Thomas said, including creating good-paying jobs that could lead to long-term careers, as well as alignment with the president’s Justice40 initiative, which mandates that at least 40% of federal climate funds must go to marginalized communities that are disproportionately impacted by climate change and pollution. 

High Country News found that 30% of jobs listed across the West have explicit justice and equity language, from affordable housing in low-income communities to Indigenous knowledge and cultural reclamation for Native youth...

While the administration aims for all positions to pay at least $15 an hour, the lowest-paid position in the West is currently listed at $11 an hour. Benefits also vary widely, though most include an education benefit, and, in some cases, health care, child care and housing. 

All corps members will have access to pre-apprenticeship curriculum through the North America’s Building Trades Union. Matthew Mayers, director of the Green Workers Alliance, called this an important step for young people who want to pursue union jobs in renewable energy. Some members will also be eligible for the federal pathways program, which was recently expanded to increase opportunities for permanent positions in the federal government...

 “To think that there will be young people in every community across the country working on climate solutions and really being equipped with the tools they need to succeed in the workforce of the future,” Thomas said, “to me, that is going to be an incredible thing to see.”"

Note: You can browse Climate Corps job postings here, on the Climate Corps website. There are currently 314 jobs posted at time of writing!

Also, it says the goal is to pay at least $15 an hour for all jobs (not 100% meeting that goal rn), but lots of postings pay higher than that, including some over $20/hour!!

They found underwater sea batteries that produce "dark oxygen" without sunlight and now there's a crisis because mining companies want to harvest them for their metals.

They take millions of years to form, and are likely essential for deep sea life, but they want to scrap them for spare materials.

And I cannot even think of a metaphor for how completely morally bankrupt this economic system is, because this is just par for the course.

As relentless rains pounded LA, the city’s “sponge” infrastructure helped gather 8.6 billion gallons of water—enough to sustain over 100,000 households for a year.

Earlier this month, the future fell on Los Angeles. A long band of moisture in the sky, known as an atmospheric river, dumped 9 inches of rain on the city over three days—over half of what the city typically gets in a year. It’s the kind of extreme rainfall that’ll get ever more extreme as the planet warms.

The city’s water managers, though, were ready and waiting. Like other urban areas around the world, in recent years LA has been transforming into a “sponge city,” replacing impermeable surfaces, like concrete, with permeable ones, like dirt and plants. It has also built out “spreading grounds,” where water accumulates and soaks into the earth.

With traditional dams and all that newfangled spongy infrastructure, between February 4 and 7 the metropolis captured 8.6 billion gallons of stormwater, enough to provide water to 106,000 households for a year. For the rainy season in total, LA has accumulated 14.7 billion gallons.

Long reliant on snowmelt and river water piped in from afar, LA is on a quest to produce as much water as it can locally. “There's going to be a lot more rain and a lot less snow, which is going to alter the way we capture snowmelt and the aqueduct water,” says Art Castro, manager of watershed management at the Los Angeles Department of Water and Power. “Dams and spreading grounds are the workhorses of local stormwater capture for either flood protection or water supply.”

Centuries of urban-planning dogma dictates using gutters, sewers, and other infrastructure to funnel rainwater out of a metropolis as quickly as possible to prevent flooding. Given the increasingly catastrophic urban flooding seen around the world, though, that clearly isn’t working anymore, so now planners are finding clever ways to capture stormwater, treating it as an asset instead of a liability. “The problem of urban hydrology is caused by a thousand small cuts,” says Michael Kiparsky, director of the Wheeler Water Institute at UC Berkeley. “No one driveway or roof in and of itself causes massive alteration of the hydrologic cycle. But combine millions of them in one area and it does. Maybe we can solve that problem with a thousand Band-Aids.”

Or in this case, sponges. The trick to making a city more absorbent is to add more gardens and other green spaces that allow water to percolate into underlying aquifers—porous subterranean materials that can hold water—which a city can then draw from in times of need. Engineers are also greening up medians and roadside areas to soak up the water that’d normally rush off streets, into sewers, and eventually out to sea...

To exploit all that free water falling from the sky, the LADWP has carved out big patches of brown in the concrete jungle. Stormwater is piped into these spreading grounds and accumulates in dirt basins. That allows it to slowly soak into the underlying aquifer, which acts as a sort of natural underground tank that can hold 28 billion gallons of water.

During a storm, the city is also gathering water in dams, some of which it diverts into the spreading grounds. “After the storm comes by, and it's a bright sunny day, you’ll still see water being released into a channel and diverted into the spreading grounds,” says Castro. That way, water moves from a reservoir where it’s exposed to sunlight and evaporation, into an aquifer where it’s banked safely underground.

On a smaller scale, LADWP has been experimenting with turning parks into mini spreading grounds, diverting stormwater there to soak into subterranean cisterns or chambers. It’s also deploying green spaces along roadways, which have the additional benefit of mitigating flooding in a neighborhood: The less concrete and the more dirt and plants, the more the built environment can soak up stormwater like the actual environment naturally does.

As an added benefit, deploying more of these green spaces, along with urban gardens, improves the mental health of residents. Plants here also “sweat,” cooling the area and beating back the urban heat island effect—the tendency for concrete to absorb solar energy and slowly release it at night. By reducing summer temperatures, you improve the physical health of residents. “The more trees, the more shade, the less heat island effect,” says Castro. “Sometimes when it’s 90 degrees in the middle of summer, it could get up to 110 underneath a bus stop.”

LA’s far from alone in going spongy. Pittsburgh is also deploying more rain gardens, and where they absolutely must have a hard surface—sidewalks, parking lots, etc.—they’re using special concrete bricks that allow water to seep through. And a growing number of municipalities are scrutinizing properties and charging owners fees if they have excessive impermeable surfaces like pavement, thus incentivizing the switch to permeable surfaces like plots of native plants or urban gardens for producing more food locally.

So the old way of stormwater management isn’t just increasingly dangerous and ineffective as the planet warms and storms get more intense—it stands in the way of a more beautiful, less sweltering, more sustainable urban landscape. LA, of all places, is showing the world there’s a better way.

I listen to NPRs environmental articles in the morning for my alarm, and today's about key deer in Florida really brought up a very good point.

Humans have done so much to negatively impact our environment. That means we also have the power to change it in a positive way as well.

"The coral reefs of south Sulawesi are some of the most diverse, colorful and vibrant in the world. At least, they used to be, until they were decimated by dynamite fishing in the 1990s.

As part of a team of coral reef ecologists based in Indonesia and the UK, we study the reefs around Pulau Bontosua, a small Indonesian island in south Sulawesi...

In many places around the world, damage like this might be described as irreparable. But at Pulau Bontosua, the story is different. Here, efforts by the Mars coral restoration program have brought back the coral and important ecosystem functions, as outlined by our new study, published in Current Biology. We found that within just four years, restored reefs grow at the same rate as nearby healthy reefs.

Speedy recovery

The transplanted corals grow remarkably quickly. Within a year, fragments have developed into proper colonies. After two years, they interlock branches with their neighbors. After just four years, they completely overgrow the reef star structures and restoration sites are barely distinguishable from nearby healthy reefs.

The combined growth of many corals generates a complex limestone (calcium carbonate) framework. This provides a habitat for marine life and protects nearby shorelines from storm damage by absorbing up to 97% of coastal wave energy.

We measured the overall growth of the reef framework by calculating its carbonate budget. That's the balance between limestone production (by calcifying corals and coralline algae) and erosion (by grazing sea urchins and fishes, for example). A healthy reef produces up to 20kg of reef structure per square meter per year, while a degraded reef is shrinking rather than growing as erosion exceeds limestone production. Therefore, overall reef growth gives an indication of reef health.

At Pulau Bontosua, our survey data shows that in the years following restoration, coral cover, coral colony sizes, and carbonate production rates tripled. Within four years, restored reefs were growing at the same speed as healthy reefs, and thereby provided the same important ecosystem functions...

Outcomes of any reef restoration project will depend on environmental conditions, natural coral larvae supply, restoration techniques and the effort invested in maintaining the project. This Indonesian project shows that when conditions are right and efforts are well placed, success is possible. Hopefully, this inspires further global efforts to restore functioning coral reefs and to recreate a climate in which they can thrive."
