In 2022, a 12 months by which 70,000 Europeans died of heat-related causes, the United Nations named Eleni “Lenio” Myrivili the world’s first-ever international chief warmth officer. A former deputy mayor of her hometown of Athens, Greece, Myrivili had overseen a multimillion-dollar price range and a workers of 500 and was largely answerable for establishing that metropolis’s fame as a frontrunner in climate-change adaptation.
Now, she is working to increase that imaginative and prescient on a world scale. Her observe report of constructing change by collaborations with nationwide governments, U.N. businesses, NGOs, foundations, academia, and the non-public sector led the journal Nature to call Myrivili one in every of 10 individuals most answerable for shaping science in 2023.
Of explicit concern to Myrivili is the affect that excessive city warmth — the number-one public well being subject cities will face within the coming many years — may have on the world’s most susceptible. In an interview with Yale Surroundings 360, she careworn the necessity to defend these populations, partially by making certain that extra financing flows of their route. “Cities which have cash can present us the best way, after which others can see what matches and what doesn’t,” she says. “However we’ve got to give attention to the poorer cities, that are those that can endure most.”

Yale Surroundings 360: What does the place of World Chief Warmth Officer entail?
Eleni Myrivili: I’m folding work on warmth resilience into the initiatives that UN-Habitat [the United Nations’ program for human settlements and sustainable urban development] is doing in city facilities. They’ve been engaged on sustainability, accessibility, fairness, and the right way to make cities extra livable, particularly within the World South, however local weather change hasn’t actually been central. My goal is to raise warmth as a problem as a result of it impacts lives and livelihoods greater than another local weather consideration.
e360: Folks appear to concentrate on the hazards of floods and wildfires, however warmth has one way or the other flown beneath the radar. Is that altering?
Myrivili: Very a lot so. Final 12 months was the most popular 12 months ever recorded. We had limitless fires and heatwaves. Folks within the Northern Hemisphere have been swimming in months that they’d by no means gone swimming. We’re all of a sudden changing into far more aware about warmth and the way it’s linked with occasions like drought, wildfires, flooding, hurricanes, and tornadoes.
“We’ve constructed cities primarily based on the concept we’ve got fossil fuels to assist us deal when it will get too scorching.”
e360: A current examine revealed in The Lancet Regional Well being – Europe discovered that in the summertime of 2022, excessive warmth killed 70,000 individuals in Europe. Is quantifying the affect of maximum warmth one thing that individuals have begun to give attention to extra?
Myrivili: The proliferation of research linked to warmth in the previous couple of years is wonderful. Research on the whole lot from meteorological impacts to impacts on the physique.
e360: How does excessive warmth have an effect on the physique?
Myrivili: The principle means our physique offers with warmth is thru perspiration. But when there’s loads of humidity within the air, perspiration doesn’t evaporate and funky us down. Our physique goes right into a panic. The cardiovascular system is affected first, because it tries to maneuver blood to the pores and skin and to our muscle mass. However then an entire collection of techniques begins to have bother. You’ll be able to turn out to be dizzy or confused as a result of not sufficient blood goes to the pinnacle, or you possibly can go into renal failure. Because of this warmth can ship individuals with pre-existing well being issues to the hospital actually quick.

e360: Warmth is a specific downside in cities, the place two-thirds of the worldwide inhabitants will dwell by 2050. Why is it so problematic in city areas? What occurs in a metropolis that doesn’t occur within the countryside?
Myrivili: The issue with cities is that we’ve got a constructed surroundings primarily based on concrete, asphalt, glass, and metal. These supplies all take up warmth and radiate it at evening. If evening temperatures don’t fall — within the Northern Hemisphere, no less than — your physique by no means actually recovers from the daytime warmth. It’s the evening temperatures, moderately than the morning temperatures, which are the harmful time. That’s the reason, after we speak about creating shade in streets or in public areas, we would like shading that’s retractable, so the warmth isn’t trapped within the metropolis at evening.
We’ve additionally constructed cities primarily based on the concept we’ve got fossil fuels to assist us deal when it will get too scorching or too chilly. We forgot that for hundreds of years individuals discovered options for excessive environments, and we threw them out the window. We had inside courtyards with water fountains and bushes. We had double roofing with air passing by and whitewashing, which displays the solar’s rays. It is a significantly essential resolution in poor nations, the place the roofs are usually concrete or corrugated iron.
e360: What have you ever been doing to chill issues down in Athens?
Myrivili: We’ve been including bushes and inexperienced areas, which, in a densely constructed metropolis like Athens will be troublesome. We’ve accomplished pocket parks and created new areas by transferring and demolishing buildings, but in addition by placing inexperienced corridors in current streets and taking away automobiles. Automobiles and air conditioners create extra warmth in public areas. We have to create inexperienced streets, inexperienced corridors for pedestrians, electrical public mobility, scooters, and bicycles. The facilities of the cities of the long run needs to be empty of automobiles. In locations like Amsterdam and Paris, they’re already doing this.
“There’s proof that when warmth waves are named, there’s a special sort of mobilization.”
We’re additionally profiting from the engineering feat that could be a 24-kilometer-long underground aqueduct constructed by the Romans in 150 A.D. There’s nonetheless water in there, clear sufficient to make use of for irrigation, so the Athens Water Provide and Sewerage Firm, which owns the aqueduct, is working with the Ministry of Tradition — as a result of it’s a monument — and the eight municipalities beneath which it runs to supply a strategic plan that can create inexperienced areas supported by the aqueduct that will probably be constructed to particular tips to make sure they cool the town.
e360: If you must knock down buildings and create new roads and new parks, you’re going to want buy-in from many various entities, every with their very own pursuits. How a lot of your work is arising with improvements and dealing with scientists and panorama designers, and the way a lot is simply attempting to get the politics ironed out, to get all people on board to make what, in lots of instances, are very massive modifications?
Myrivili: Because of this the chief warmth officer position is essential. As a result of you must have any individual who’s doing all of the politicking and who’s keen to knock on doorways and get completely different individuals to collaborate. It takes a very long time, and it’s not straightforward. The U.N. is a gigantic administration, so it may be troublesome to navigate.

e360: You may have a grasp’s diploma in efficiency research and a Ph.D. in anthropology. Is that this the place these research are available in?
Myrivili: I needed to be a theater director. I by no means thought I’d get pleasure from being an administrative director, however I actually cherished it. After I was deputy mayor, we had 500 individuals within the division, and I loved putting in a staff that labored effectively collectively. Anthropology has to do with having the ability to perceive completely different views and see that communities have completely different wants and references and methods of speaking about issues. Anthropology has helped me to not be a vacationer, to be extra a part of the neighborhood wherever I’m going.
e360: You’ve talked about naming impending warmth waves, the best way we do with tropical storms and hurricanes.
Myrivili: There’s proof that when warmth waves are named, there’s a special sort of mobilization. However extra essential than naming is categorization. This is able to be primarily based on a system on the metropolis stage. You must have a way of when it turns into actually harmful and dangerous the place you’re.
“In the previous couple of years, the variety of individuals shopping for air conditioners has grown exponentially.”
However there are answers that may assist defend essentially the most susceptible. Labor ministries can enact legal guidelines that defend laborers, ensuring that individuals working beneath harmful circumstances — significantly in lower-paying jobs like building, agriculture, and supply providers — aren’t left to burn beneath the solar. When can individuals work, and beneath what circumstances? When ought to they not work in any respect? How can we be sure that we verify in on individuals, particularly older individuals residing alone? We are able to create neighborhood networks with volunteer providers and introduce apps that remind kinfolk to verify in on of us.
e360: We all know what a distinction political management could make, for good or ailing. Contemplating all that’s occurring geopolitically, how can we keep hopeful?
Myrivili: I see the non-public sector coping with local weather change increasingly more severely, as corporations understand that their techniques are depending on logistics, transportation techniques, and pure assets which are coming beneath risk.
On the U.N. Local weather Change Convention in Dubai, 63 nationwide governments signed onto one thing referred to as the World Cooling Pledge, committing to cut back cooling-related emissions whereas growing entry to cooling. That is essential as a result of we’ve got near 2 billion models of air con across the globe. In the previous couple of years, the variety of individuals shopping for air conditioners has grown exponentially, particularly in nations with rising center lessons.

e360: Singapore appears to be main the best way on the subject of warmth administration.
Myrivili: The town-state has accomplished a tremendous job creating primary guidelines by which we will perceive the right way to create cooler districts, neighborhoods, streets, and buildings, from the massive image to the small. When establishing new neighborhoods, they take into account how excessive the buildings needs to be, how deep the canyons, the right way to manage the shading that comes from the buildings. And Singapore’s nice as a result of it’s a metropolis and a state, and it has cash.
e360: However what about locations like Dhaka and Lagos?
Myrivili: Now we have to mobilize financing and create insurance policies that may assist individuals in these cities. That’s why I needed my place to be a part of UN-Habitat, as a result of that’s the place the main focus is.
e360: Are there monetary mechanisms, by the World Financial institution or in any other case, particular to warmth in cities?
Myrivili: That is a part of my massive effort throughout the U.N., to create a selected mechanism that may goal monetary help to cities around the globe for saving individuals from shedding their lives or livelihoods to warmth.
Now we have to ramp up resilience and adaptation financing as a result of we’ll save lives and ecosystems. Though warmth would be the number-one public well being subject that cities will probably be coping with within the coming many years, it’s nonetheless troublesome to get funding. We’re not prepared for it, simply as we weren’t prepared for Covid. And we’ve got to prepare.
