"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."

[elithemiar-blog]

Danny gets invited into a robotics/mechanics club after he mumbled out the basic idea of his parent's latest invention just by looking at it, the name did help.

He doesn't have much of a choice to recognize what an invention can do based off of its look for his safety.

So mechanics and engineering he just starts picking up from his parents through association.

At some point, he has to modify one because it hurts both humans and ghosts.

His parents are so caught up on the fact that it hurts ghosts as intended that they completely miss that it hurts humans too, severely.

Danny, and Tucker when needed, start modifying the weapons for people's safety. Which Danny gets really good at and starts taking his parent's blueprints and building safer, and mostly better, inventions.

So, when this new classmate overhears the trio discussing on how to fix it. They think Danny would be a great addition to the club, and when they bring it up at their next meeting, everyone else either doesn't believe them or is joking.

Due to gossip and high school hierarchy (by Casper standards), Danny is a freak, loser, and stupid.

This classmate brings Danny's intelligence to himself and tries to urge this kid to come to the club one day after school.

Danny downgrades his own intelligence on engineering that the classmate is befuddled, until being at Casper for longer they understand on why this is.

A school event has this classmate trying to strike high praise on Danny, but even his parents kind of bat him aside to talk about ghosts.

People start gossiping that this classmate has a crush on Danny.

Eventually, they do get Danny to a club and the rest of the members kind of call him out on his crush, in front of Danny. However, he does prove himself and the club agrees to invite him to some kind of multi-school engineering showcase, and they do need one other person to make a full team.

He really doesn’t want to go. Somehow his parents are pushing him to go. At some point, somehow, he's being required to go.

Maybe Tucker and Sam urge him to go, who already noticed Danny's talent. He still doesn't want to leave Amity, but with his friends pushing him to have fun he's more willing to think about it.

Maybe the trip becomes a 50/50 extra credit opportunity on his math and science grades, which he needs.

Marvel: Tony, Peter, and/or Banner are at this event to find future employees or award scholarships.

DC: Bruce and/or Tim are at this event (maybe another as well), to also find future employees or award scholarships.

Maybe there's some kind of lead revealed during this event that helps a case.

They find Danny being isolated by the club except for the classmate and they're curious on why.

The classmate is giving high praises, gifting information that Danny doesn't want revealed, to these people who will actually listen.

This team gets challenged to build something different.

The classmate turns to Danny to help out and he gets invited by the rest, but he doesn't get a say...

Danny sees something wrong and tries to say something, but no one let's him get a word in..

When the build gets judged, it doesn't work. Danny with random parts in hand, fixes it on the spot adding a little touch that makes it work and then some.

He gets high compliments from these very smart people, but he brushes them aside. Not realizing what he did, he'd just really wants to get back to Amity.

While the event is still going on, he gets pulled aside to look over a project or design and he can tell what needs fixed or how to reroute power better (purposeful mistakes meant to challenge him).

Here he is, at an event for school, being given complements and not really noticing.

These people very curious on who this kid is goes searching. Maybe the club kids tell the not-paying-attention-club-advisor that he did nothing.

Maybe the one doing the complimenting calls the school and, petty tattles on the club, gives full praise and offers a scholarship.

Someone can be so focused on either working on what they want to do or what they have to do (in Danny's case), that talent found isn't recognized even if highly complimented by an expert.

The mental image of Tim inviting Danny to the manor to help out with a WE project, and Tim is trying to get him to recognize his own talent. Bonus points if its vigilante associated (like Nightwing's eskrima sticks malfunctioning and sleep deprived Tim can't figure it out). Bonus points if the rest of the family are there over seeing.

Maybe he can't be an astronaut anymore cause he doesn’t fit certain requirements. Maybe he can still work for NASA despite his grades, he fixes a missed problem that would've made the rocket launch unsuccessful, and it was a last-minute change.

Scientists have uncovered a new source of hazardous "forever chemical" pollution: the rechargeable lithium-ion batteries found in most electric vehicles. Some lithium-ion battery technologies use a class of PFAS chemicals, or per-and polyfluoroalkyl substances, that helps make batteries less flammable and conduct electricity. Scientists found high levels of these PFAS in air, water, snow, soil, and sediment samples near plants that make those chemicals in the US, Belgium, and France, according to a peer-reviewed study in the journal Nature Communications.

sometimes i feel like im making a mistake by not learning mandarin and getting an environmental engineering degree

[ominousvibez]

i know a lot of people tend to define dani/ellie's "obsession" as the ocean to go with danny's space obsession but tbh i feel like as dani gets older she's going to do a lot to separate herself from her identity as danny's "clone" and become her own person

like, that's why i love that the fandom has adopted the "ellie" nickname so much for her. i so wish the show went on for longer with more competent writers or the comic could expand on this maybe but i think finding her own identity and voice would be such a powerful narrative. you're made for one thing but you don't wanna do that, so now what do you do?

(tbh that kind of identity exploration is probably too anit-christian for b*tch h*rtman so i'm glad he didn't get to touch it)

it's canon that dani goes off and travels the world, so why not have her obsession be traveling? she's got a huge case of wanderlust. she likes the outdoors, she likes hiking and camping and is a huge granola girl. like, i think that kinda just fits her a bit more, in my opinion. traveling/exploration.

between Dread continuing from a game on GBA (and really every game prior to that too) and Prime 4 continuing from 2 games on GameCube and Original DS, Metroid has the longest narrative endurance of any multi-creator series I've ever seen. Threads left in stasis decades ago when the series was shelved picked right back up once development resumes—an entire generation of developers later—like nothing ever happened

hearing about how many students/peers my age actually use chatgpt is terrifying

[notquitequelled]

nothing's wrong-- i'm just a STEM student...

[i rarely see stem rep-- so here’s PART TWO! (find part one here) the extended edition of ‘stoners in stem’ highlighting the parts of this life that i find myself loving ;p

Thinking of doing sectionals (Physics, Environmental Studies, Mechanics, Entomology, etc.), so if there are any suggestions you'd like to highlight, plz tag or comment !!]

TAG YOURSELF !! I LOVE SEEING WHAT YALL GET UP TO !!

slightly concerned glances being shared between even the worst of acquaintances when your mentor drops some crazy lore surrounding how they entered their field(s)

good god. the apple-cider vinegar and dish soap gnat traps. honey alternatives decidedly never cross anyone's mind (nor the threshold of the lab for that matter)

walking the fine line between the Ridiculous and the Logical during data analysis like the two aren't twin kings of ruin

noncommital shrugs when asked anything about your preferred diet or eating habits

writing exclusively with pen, or exclusively with pencil. feeling borderline disgusted having to use the other when you forget your own

'Why do you care?' 'Why don't you??'

Every documentary you watch absolutely changing your life and challenging your worldview

Either hanging onto your textbooks like a lifeline or forgetting about them as they gather dust under your bed. maybe you never bought them at all-- pirated PDFs littering your desktop

anything in jars being considered decor (snakes, regurgitated bones, praying mantis egg cases)

seeing the slant of fences, trees, and lamp posts-- thinking of all the wind and weather that's passed along the same path you have

TREEHUGGER !!! HA HA

the clean quiet that hangs over the linoleum early in the morning; the warmth is not so subtle now that you've rolled up your sleeves.

teaching everyone around you how to bypass PAY FOR ARTICLES because knowledge should always be F[ree]INED [inspect, gear, disable java]

having to just sit by n watch while someone pointedly ignores your input, and a totally avoidable incident (that could have totally been avoided) is not, in fact, avoided

dealing with the consequences of that incident for the rest of the experiment/project

blank stare, lips in a placatingly firm line as you nod along with the stern talking-to you're being given. their words going in one ear and out the other because you're already thinking through another way under admin's nose

whaaaaat ? how'd those locally indigenous species just pop up everywhere overnight, ha ha ? wow nature is crazyyy

digging through public records for one reason, only to uncover an entirely different can of worms about the institution you frequent

digging in the literal dirt and uncovering literal worms lol amirite guys

'Please remember that this is just a prototype and that i'm it's in a very fragile state right now.'

going crazy trying to figure out what a specific testing company uses in their chemical compounds, because good fucking god how are you supposed to cite the evidence if you can't even label what it is?

a disastrous experiment being abandoned like Chernobyl once determined beyond salvation-- everyone curious to see how it'll develop and fester when left on its own

'life imitates art,' you think, as you finally recognize one of your unnecessarily complicated formulas being represented in your daily life

often being so bad at the thing you love that you can't do anything about it but laugh

staring for so long at something during a lecture that white begins to leech into your vision. you should probably blink a few times so people don't begin to suspect you're a reptile (even more than they already do)

'Don't.. don't look at me like that...' [speaking to a(n) (INSERT NAME OF LITTLE CRITTER HERE) you had to gently move onto a little scale to collect data]

honing in on where your talents in your field lie; the disappointment in finding your limits that turns to indifference when you remember you're still phenomenal at a million other things you enjoy

'i want to study you like a bug.'

thinly concealed irritation masked by a patient smile and a small 'mhm' when someone tries to explain your life's purpose TO you (ten dollars says they're wrong about it, too)

'and you want me to run this... on a full moon?' 'don't start with that shit again.'

yer disgust is lookin' a lot like morbid curiosity these days...

a lot of your scientific conclusions being discerned by common sense ('Please just use your cognitive functions, you guys...')

a clean earth sciences lab floor.. my white whale...

the small (increasingly large) pile of recyclable material that's waiting to be torn apart or filled with soil and plants; it topples over when people walk past, but no one can bring themselves to throw any away

'all this only cost me like... $270. which is crazy given that these're the real fuckin' deal with solid steel reinforcements.' 'man...this shit is so gonna blow down.'

leaning into the obscure, instead of away from it out of habit; seeing its effect in your daily life and work

all the plastic utensils in the dining area being stolen for diagrams, leaving behind only the reusable metalware. this is unexpectedly admirable of the engineers, if only to those who care about the inadvertent environmentalism

taking things apart to see how they work-- having very little planned on how to put it back together

'I don't know what you want me to do about that, you created it.' 'Not on purpose!'

downloading photomath during testing season. your doubt being palpable over your (in)ability to solve simple equations

carrying hand lotion everywhere you go because of how often your work has you washing your hands; colleagues and peers holding their hands out like beggars in a Mel Brooks film ('lotion... dollop of lotion for the poor D:')

borrowing chemical-grade goggles from the lab before going out to protest; supervisors giving you dubious thumbs ups while they 'accidentally' leave the key to the goggle sanitation station right by the cabinet..

'Now that you've poured your blood, sweat, tears, and other secretions into this project-- decide if you want to take it home to maintain, or have it eradicated.'

utilizing the public library, but having to double-check the internet before citing anything from the books you pour over because your city is more concerned with the way the building looks than the content it supplies

'The Martian,' both the book and the movie ... Mark Watney you will always be famous,,

'Why are you taking so many difficult classes at once?' 'My entire degree is difficult classes.'

carrying a small journal everywhere in an attempt to organize your thoughts, tasks, and reminders (you've never looked back on a single you've written, but you like to think it at least helps in the moment)

being torn between the scientific evidence that supports getting eight hours of sleep and your own hubris. you can stay up it's fine. it'll be fine.

you're not fine but at least the lab counters feel so nice against the side of your face

WHAT THE FUCK IS EVEN A KILOGRAM 🦅🦅🦅‼??!!!!!

having no idea where your degree will take you, giving everyone who asks a different vague answer

hands being littered with cuts and burns; not being able to stop yourself from touching even at the worst of times

geeking out over carbon sensors and ammonia regulators your supervisor managed to convince the department to splurge on (nothing provided by them will enter your lab for another three semesters)

being one of the most prepared people ever when it comes to disaster prep; this includes zombies

'this was not.. our intended result... someone get the shovel.'

pettiness infiltrating your daily life in the form of utilizing your talents; coding programs and drawing up diagrams and running tests just to prove someone wrong (or just to fuck with them)

studying with your liberal arts friends; both of you staring at your respective incomprehensible lines of symbols and words that neither of you have the brainpower to comprehend. most of the lights are off and the library closes in ten minutes, but you know the night staff and they've learned to keep their distance until absolutely necessary.

2.8.2024

The past few weeks have been absolutely insane; although stressful due to long hours in the lab and balancing a million things, I can't recall a time I've learned more in such a short period. There is of course still SO much I don't know within my field, but it's satisfying to feel myself becoming more knowledgeable by the day.

Towards the end of last semester, I spent some time reflecting on how my first year was going and considering how to really develop as a researcher. The gap between a first and second year PhD student is huge, in my opinion--since I switched fields from undergrad, it's probably even more true in my case. I did learn a lot last semester, but I was still settling into a new environment and program. There is a lot to get adjusted to in this lab; it's huge, a bit chaotic, and used by multiple groups.

I am finally feeling more confident and independent, so I think this is the time to really grind in order to be where I want to be going into my second year. In addition to ramping up lab work, I've been trying to read way more. For each article I read, I also make a slide in an ongoing PowerPoint that summarizes key findings and any notes or questions I have. This isn't so much an organizational method (I use Zotero for that) as it is a way to follow interesting threads in current research and develop a habit of active reading.

If anyone has a reading practice that really works for them I'd love to hear about it :)

you quit your software engineering job to pursue environmental science?? do tell!

(i have a software engineering job. it makes me sad.)

so when i was like. 10. i had this teacher who taught us basic scratch programming. and i was like. freakishly good at it. i picked it up super quickly and was even helping the other students to fix their problems. and so he said to me "you know, you could be a great computer programmer one day" and i was like. yeah! i could!

so throughout highschool my One and Only goal was to become a software engineer. every time i went to the career counsellor thats what i said. so i did computer science at gcse, and got a 9, and i did computer science at a level and got an A*. (i did other subjects too of course. but those were the ones i was focussed on)

then i finished my a levels and i went straight into looking for an apprenticeship. no one was really interested in me because i didnt have any experience or a degree. so then my dad got me an internship with some guys he knew at a company that worked in his building, and i managed to build up some actual industry skills. then i got an apprenticeship! it paid super well and the team was great and it was work from home.

and i hated it.

i was just sitting in my room at my dads house 9-5 mon-fri writing code all by myself. it was lonely and boring and i didnt really know what i was doing. it was supposed to be an apprenticeship but it just felt like a job. they didnt teach me how to do anything they just said "do this and come to me if you run into a problem". half the time they didnt even give me any work to do for days at a time so i was just watching youtube or scrolling on tiktok. which sounds great but it wasnt because i felt guilty the whole time and was terrified of being found out and fired, even tho it wasnt my fault? they literally werent giving me work to do?

anyway. a few months into it i was like man Fuck this. im going to university. so i started looking at courses. it actually started with astrophysics, but since i didnt take a science at a level i didnt have the requirements for that. then i found environmental science! it was all the stuff im passionate about: climate change, conservation, natural processes and earth science. so i worked on my application letter and applied, and i got in!

so i went to my boss and was like hey. im putting in my notice. i got into university. and they were like "oh noooo we're so sad to see you go :( you were doing so well and we were so pleased with your work and your progress :(" (and i was like. huh?? i literally didnt fucking do anything. but oh well.)

so i worked until the end of my 6 week notice and then i handed my stuff back in and left. i had a bit of a summer vacation and then started uni! and ive been here for just over a year now :)

its honestly so much better. i have so many new friends, i got to move out of my mums house, im in full control of my life.

so take this as your reminder that its never too late! you can always change your path.

you are in control.
