I think the video gives an excellent strategy, i.e. a community strategy relying on shared AC-equipped shelters (for me in Belgium, the library serves as a good climate shelter). What is important to iron out in this strategy is not only getting isolated people to safety, but also to have labor laws fitting this strategy (i.e. laws which forbid employers from preventing their employees to find a shelter when the wet bulb temperature is almost in sight). I'm sure people will also want more individualistic, local and acute strategies to cool down. Say, if the place where you sleep is without AC, there is the option of opening all the windows early in the morning a few hours before sunrise and maximally venting the whole space, letting all the walls give of their heat as much as possible. For poorly insulated houses, you can spray the outside of the walls and the roof with water (at noon) while keeping the windows closed. More generally, you can rely on evaporative cooling strategies as long as humidity doesn't approach 100% and you don't immediately have to be in the space where the water evaporates into. Of course you have to see whether this is responsible water use within the broader local context. On a more long-term basis, for roofs, cheap white paint (lower albedo) competes with solar panels (e.g. white paint on northern-sloped roofs).
I stay home with the AC on. I'm autistic so going to a public place would be worse stress than suffering heat. Also, your C/F conversions are off sometimes, e.g. when it says 5 degrees C lower, the screen shows 41 degrees F which is nonsense in that context. 5 C difference equals 9 F difference.
Climate polluters have gone from "climate change doesn t exist" to "see? It s cool and we can adapt". This kind of videos is just playing along fossils fuels' spiel. They don t cover the issue of what we re going to do in 20-30years when temperature will be even higher. Adaptation is a lure, we need to stop the change.
That second type of community shelters when people goes to have a drink in a cool space solve the problem only for humans, when the first type with trees and shade solve the problem also for other living creatures.
One of the big changes we are seeing is hot nights! We never used to run our cooling system at night. We’d run the house fan and bring in the cool night air. No longer. And we live in the country, surrounded by ranch land and forests, not in a hot city full of concrete. Our main mitigation has been to install solar. Our for profit electricity provider is very corrupt, so we pay incredibly high prices for electricity. Our next step is to buy batteries and perhaps go off grid, to starve our corrupt, electricity cartel!
If you are not a fossil fuel producer country, you will buy that from some other country resulting in trade deficit. Then oil/gas price will be determined by rich countries who are competing with you.
I have a similar problem. Since I live in an old house, despite nights here are still cool, inside the house the structure keeps humidity and hot inside making you unable to breathe. I think I have to make some works to fix such problems. Also my windows acan be opened only from the lower side offering no space for hot air to go out. 😑 I'm dying here. 🥵🥵🥵
Nope, trees have higher albedo compared to white reflective surfaces. Trees also require a lot of water and adds humidity, which increases heat stress. Both sensible heat and wet latent are detriment to human physiology.
@user-qe9bc8rk1v obviously you don't know what you're talking about since you just said the same thing I did. Trees release extra water which gets evaporated back into rain clouds, we built cities all wrong that's why Temps are higher. Are city structure hasn't changed since the Roman empire or Chan dynasty.

This video is more about climate shelters. It doesn't tell us how to survive heat waves in a city or what precautions we should take during a heat wave.
Why in hot countries do people not go out during the peak heat hours? Why don't you expose yourself to direct sun with physical activities? Why they keep their houses in the dark, stopping the entry of light and sun, why do they open the windows at night? Why is their diet lighter and do they drink more water? Why Do you wear lighter cotton or linen fabrics? You just have to observe what customs hot countries have. There is your answer.
You've made an error with your temperature numbers in Fahrenheit. E.g. while an absolute temperature of 5°C is indeed 41°F, a _difference_ of 5°C is only 9°F difference since ±1°C = ±1.8°F or in other words any one degree step in Celsius equals a step of 1.8 degrees in Fahrenheit. In short: America should finally adopt the metric system.
I have lived in US for the last 20 years. I still change my weather app to celsius. Even though I can convert between two in my mind, I refuse to use fahrenheit. It just doesn’t have to same feeling. “Oh, it will be freezing tomorrow. It will be below 32 degrees”. WTF
Also mixing real temperatures with "feels like" temperatures at 8:00 is extremely misleading. Rio de Janeiro has not reached 62°C, it was at 42°C with percieved 62°C. Still incredibly hot, but not "you can slow cook food by just leaving food outside"-hot.
@@KarrasBastomi It isn't. All the temperatures were given in degrees Celsius but on screen they were also stated in degrees Fahrenheit because about 300k people across the pond still haven't got the memo...
Air temperature is just part of the story. The heat is a bigger problem when humidity is high and that's what happens in barcelona. A few years ago I was there with 33ºC and 85% humidity and almost die waiting for the train while back home with over 36º it was manageable because it was drier. The solutions shown here are great but don't really help with the humidity issue
Most people who live in hot sunny countries are shocked how hot 25 degC and 90% humidity is on an overcast day on the west of Europe. Thankfully that still won't kill you because it's far enough under 37 for the body to cool, but temperature is only a part of how heat is perceived. This humidity is also the reason breathable jackets are worthless in humid climates as the vapour only goes out through the pores in the jacket when there's a large humidity gradient between the inside and the outside.
Yeah, all those Blue adaptation would stop working, except drinking cool water. Those spray fountain and stuff, if the humidity is low, it works really well. Because Water is really good at absorbing heat, so adding water with just slightly lower temperature into the air, the overall temperature would drop easily. But if the humidity is really high, the water in the air would quickly heat up your new water droplet. The overall temperature doesn't drop that much. And the air become more humid overtime, your sweat can't dry up easily, trapping a layer of hot humid air around your body.
Can we get rid of asphalted roads inside cities and redesign it with more trees, for pedestrians, cyclists and only emergencies services? Build wider bike paths to encourage people to buy cargo bikes instead, improve public transportation efficiency, capacity and accessibility. Also, for households, Passive House is a German concept that isn't applied in most places. Buildings in Germany are being built only for winters. I just moved in as a the first tenant in 2024 and my apartment has no cooling features, other than I should close the roller shutters like the rest of the country. There are so many methods to incorporate, but we don't see anyone taking action.
Barcelona is also implementing all these, removing roads to convert into gardens and including insulation and other passive temperature control measures into the new building codes.
@@anniestumpy9918 People have been living in far more extreme climates throughout history. It's a matter of adaptation. Climate change means the morphology of cities must adapt again to their environment. That's the true long-term challenge.
You got me good......learned something new here for the first time in what feels like 30 plus years.......saw the thumbnail and thought this was gone be about beating somethin else.....lol.....but here I am...CLIMATE change IS REAL , and I'll be tellug every one I know from now on (except the hogs that upend my rare flower collection night after night. we are not on speaking terms (
In spain, Barcelona is not the worse, however have already high humidity, so it is not easy reduce temperature increasing humidity, they make a good started but i consider that the city should focus more in the street than on the shelters
We Barcelonans already know how to live in the heat and foreigners pay a lot of money to come and live the experience. You see them sitting drinking alcohol directly in the sun, at 3:00 p.m. with 40°, cooking Like chickens, you see them running around melting like ice cream. We see them and we laugh. They pay for that.
Wind, water, shade, insulation, convection, and relaxation; that's what you need to beat the heat. Interestingly, old cottages may be the key to passive cooling. The thatched roof gives shade to the inside, and its eaves shade some of the outside of the house. They catch and keep water, letting them vaporize when its hot out, which cools the place. Green plants hanging on and covering the walls do the same thing. The tall roof allows warm air to rise and slowly go through the thatched roof, vaporizing the moisture. Mud walls, be they cob, daub, or adobe, insulate the place. That is, it catches the heat when it's warm out and releases the heat during a cold night. It also catches moisture that vaporizes when it's warm to cool the place. The walls are whitewashed outside, which reflects the heat out of the house. Small windows only have wooden shutters, which can be opened to let in the breeze and let out hot air, as well as closed to stop sunlight coming in from a particular direction. The chimney, when there's no fire, acts as a solar chimney, that is, it gets warmed up by the sun and uses convection to let the warm air inside it to rise out, which creates suction to draw air from inside the house, thus also creating a breeze within. Doors are often half doors, so the top half can be opened to let more breeze in and heat out and can be closed entirely to keep sunlight out. Such a cottage was small, allowing a small breeze to cool more of the house, and there was only one room with no partition, allowing any breeze to flow freely inside. Flowers in the garden and in clay pots within would add a sweet scent to the breeze. The dirt floor (earthen floor) and the kitchen garden around the house would also catch and keep moisture to release as water vapour when it's warm. The breeze picks up water vapours to cool the area. Beds were linen sacs of hay or chaff, which reflected rather than kept heat, keeping them cooler to touch. Woven rush mats laid over some of the dirt floor, which reflect heat away and kept moisture on them to vaporize easily. Stool seats and chairs were short and made of wood and rush. Of course, it helps being barefoot, wearing flowing linen or cotton clothes, and keeping one's bedstead and seats short as the cooler air is closer to the floor
Climate shelter doesn't need to be an official designated place. It can be unofficial designated place as well, like the bar, library etc that the common people say in the video. It is actually this unofficial designated climate shelter that need to be invested by the government.
Winter where I live, Melbourne, but last summer when the temperature exceeded 35 Celsius, the pool I go to regularly was free. Lots of Australians go to the malls or movies. But none of these work on very hot nights. I'd also like to hear solutions for that.
Correct. The best first world answer is get a small room specific AC. I sleep, in my room. So I weather sealed my room and installed an AC. I have it run for 1hr and auto shut off. It quickly cools the room, removes humidity, and I sleep quickly. The room will slowly warm up but I won't notice till it's time to wake up. Saves a lot on energy. Cool yourself not the whole house.
I grew-up working in a greenhouse. No environment needs more humidity; evaporative cooling contributes to a greater problem. The heat-index, or wet-bulb temperature, is greatly a measure of humidity, a situation where the temperature is high and one's perspiration evaporates slowly. When the heat-index is high, humans can't benefit from the endothermic phase-change (absorb heat energy) of liquid perspiration to water-vapor. A power outage following a tropical storm in Texas, recently took the lives of some of its most vulnerable residents in Houston. Houston is a place where evaporation rates are slow, due to low-altitudes and high humidity. Comparing similar latitudes, Houston, actually has less sun-exposure than climates in the high altitude and dry Southwestern United States, west of it. Water-vapor is also a greenhouse gas. When pavement, soil, or buildings absorb visible light, it converts that energy into long-wave infrared radiation, which is emitted from that material both day and night. Human metabolism also is a source of infrared radiation. Atmospheric greenhouse gasses convert infrared radiation to heat energy, increasing the temperature of the atmosphere. This is why dry climates, experience lower temperatures at night, there is less an insulating-effect of humidity, as understood by the greenhouse effect. Any benefit of using vegetation for evaporative cooling is ultimately reversed by precipitation, where condensation is an exothermic reaction, increasing the temperature of the atmosphere. Vegetation attenuates light, but, the benefits of shade is restricted to a confined space. Also, vegetation interrupts any passive-cooling performed by a natural breeze. As far as carbon sequestration is concerned, it is more complicated than it is often touted, as decomposition of vegetation works against the process of photosynthesis, and methane, an other greenhouse gas, is often associated with vegetation decomposing in anoxic environments, such as animal digestion, anoxic composts or landfills, and reservoirs or retention ponds. Introduced vegetation in the built-environment is complicated and energy intensive, with uncertain benefits, particularly when you consider the climate of the overall region, and not an isolated environment in the city or suburb.
I live very close to Barcelona, and it's mostly the lack of parks and green areas on streets. As you showed, one of the climate refuges, is a school, closed in summer most of the times, and also on weekends, or libraries... Yes, there are trees and bushes on streets to give shade, but it's not enough. Plazas are mostly asphalt traps, fountains doesn't always work (as shown), and the water of those fountains, yes, it's drinkable, but tastes very bad depending on what area of Barcelona you're in. If you go to the very center, say, Arc de Triomf, Plaça Catalunya, Las Ramblas or Plaça Universitat, that's a literal pan. People who lives in the center are mostly wealthy, and in the outskirts, like in La Prosperitat, as you showed, they can even afford ACs, people has very low incomes, and their only choice is going to a bar that has AC, or have a drink. It's the lack of political response and poor urbanistic planning, the only people who care is cooperatives like that one from neighbors for neighbors, without any help from the government or the District. When I was a kid, parks had a lot more green, but that costs money to mantain as it should. A very good example is Glories. When in 2004, the Forum was a big thing, the Glòries drum, it had a very nice park inside, and in 2010, it was demolished to make a massive asphalt zone, with a few trees here and there, not even planted on ground, but in plastic planters ugly as a sin... Barcelona was a very nice place to live, not today, sadly. Great job, I enjoyed the documentary.
This is why I don't go on holidays anymore and stay in the cooler North of EU. Nevertheless heat is here as well of course, the difference means extending my life time, being chronically battling with health issues. Yet I always wonder when the heat will trigger an ice age. And whether we already prepare for that one change as well. We are facing extremes, while longing for balanced climatic circumstances.
Of course, we are going to install them with the money we get from the tourist tax. So that the poor tourists feel more comfortable. Do you know the amount of heat generated by the outdoor unit of an A/C? If you have one check it out for yourself, the outdoor unit.
You could try building cooling towers like they have in the Middle East? They're built right along the street to drive cooler air down toward the sidewalks. They're also built into homes & other buildings for natural cooling.
When a foreigner goes to live in a country with sun, she discovers the heat and has to make a video about it. Now at least you have A/C but before not even that and we worked the same. You see foreigners sitting eating in the sun, drinking wine, running around at 12:00 with 40°, wondering why we don't go out outside at noon, believing that we are lazy because they do not conceive in their tourist mind that we are working. Well, so you have discovered the heat and you have to live a normal life putting up with it? That's what we've been doing for centuries and we don't spend the day lying around waiting for them to do so.
In South Korea, banks. Air-conditioned banks. Banks used to be an informal place of respite from the hot summer heat for decades, and now there are signs on bank doors that say people like the elderly can come in and "chill" without repercussion.
You won’t believe but in the Baltics we have also periods with 35 or higher under the sun and this is north of Europe. In June we had higher temperatures than in Italy or Spain or Portugal (have friends there so checked)..

Trees really are the key to tackling the climate crisis. They modify the hydrological cycle, transpire and absorb water, control speed of run-off on hills and prevent soil erosion and flooding, create biodiversity, microclimates and habitats, moderate wind, lock up countless tonnes of carbon, provide materials and food and keep us cool. In the UK we have destroyed much of our forest cover. In Wales and Scotland vast areas have been denuded to accommodate millions of destructive, methane emitting sheep. In Wales people live in cramped houses or are homeless while millions of acres of grassland are provided for 10 million sheep (the government actually gives wealthy landowners money to do this) which can be seen luxuriating in their expansive open spaces, roaming free on ‘countryside’ to which most of the 3 million people in Wales have no access. Many people here have no land and many no garden and the towns are mostly treeless too with nowhere to walk or children to play safely
Green spaces and founains are a nice idea. They do require lots of water though so you can't really use them that much when you have a drought going on like in Barcelona at the momoent. AC and solar work better in that scenario.
It’s obvious that it is so hot in that city because there no trees. Create micro-parks as cooling centers, even if you have to tear down existing buildings to do it.
Water ain't good to drink in Barcelona. Lots of liver issues if you do. There's massive agriculture for exportation, that uses most of the available water of the country. They ask for the citizens colaboration but if things where done properly...
You messed up a little bit with Fahrenheit scale. 10 degrees Celsius hotter is not 50 °F hotter, it is 18 °F hotter. 5 °C cooler is not 41 °F cooler, it is 9 °F cooler.
In the south of Spain and other extremely hot areas in the world people has been doing that since always. And we have been classified as lazy people by the regions with better summers. Now that everywhere is getting hotter those areas with better weather do what others have been doing for decades and they call it innovation.
3:25 that wasn't true up until a few years ago, I believe, we had one of the highest aerobic microorganisms concentration in water amongst spanish cities lol
0:43 “Barcelona is the city many look for inspiration” - all DW videos on Barcelona claim this… Barcelona was the worst city I’ve visited in Europe, a sea of asphalt, concrete, smell of car exhaust and heat. If you go south to Seville, which is also Spain, it has lots of parks, trees and narrow streets designed to protect you from the heat - it’s in the same country and much better than Barcelona.
So if you have mountains and a coast, it should be easy to regulate temperature. Make Barcelona a big Air conditioning unit. Pump water from the sea towards the mountains and let the mountainous altitude cool the water and run it down into pipes through Barcelona streets. for the size of a city like Barcelona, this should be possible. In India, there's an ancient castle in the state of Rajasthan called Hawa mahal. Temperatures in Rajasthan can easily touch 40 -45 degrees. The hawa mahal uses convection currents and smart window design to keep the interiors at least 15-25 degrees cooler depending on wind. (hawa means wind). Even Egypt had a smart way to keep their homes cool without an Ac in the hot summers.These officials from Barcelona need to take a world tour, especially in hotter countries to learn smart architecture and systems that have been in place since centuries.
Thats an expensive way to do a simple thing. Just build internet cafe and bars in the shape of huts along the beach so people will have a windy shady place to work and rest for a small price
@@DieNibelungenliad Barcelona is a small place. It should be doable. And it's not the whole city. It's only in parts that get really hot. Satellite imagery will show the hotspots in the city.
yes but the problem is, in other places it was designed to trap heat since in winter they get very cold and so it becomes unbearable, and plus most people aren’t used to it, but yeah in hotter countries they’d build with better AC’s and buildings that aren’t designed to trap heat
Goood morning after super . These kinds of heat shelters were always present in Türkiye . İt was under a big tree ( mostly plane trees ). Trees are the solution
Again put the money we pay on our buildings and isolate them better 😅 I have been living here in Barcelona in a building from the 50's with No isolation close to La Prosperitat and dude it was ultra warm and super super cold in the Kitchen (around 6 degrees on the harder days, inside!) Why is it? It is due to really very poor isolation. That's the worst issue. Really very cheaply done buildings are 95% of the ones we live in Also the pedestrian zone shown? It's only bricks and no trees almost. It's very badly done
Fact check maximum temperature in Brazil please. According to wikipedia: 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
Per their own source in the description, Rio de Janeiro reached perceived 62 C, and actual 42 C. Mixing both and showing that figure without context is misleading.
Thanks for catching that, the temperature on screen for Brazil at 8:04 refers to the perceived temperature. The actual high was 42 C. We've added a clarification 👌
Where I live some cities get to 40 degrees Celsius or more. Yet no heath deaths are reported nor there are any climate shelters. To see that Europe worries because you get to 24 degrees is hilarious.

around 7:15 there is a mistake in the C to F conversion. a 5 C gradient is not a 41 F gradient
Same at 4:01. 32 is an offset and is not included while working with relative values. (it offsets itself)
40°C in Italy... without counting humidity that make the perception of it even higher. 🥵🥵🥵🥵
I'm dying fried.
In spain, Barcelona is not the worse, however have already high humidity, so it is not easy reduce temperature increasing humidity, they make a good started but i consider that the city should focus more in the street than on the shelters
We Barcelonans already know how to live in the heat and foreigners pay a lot of money to come and live the experience. You see them sitting drinking alcohol directly in the sun, at 3:00 p.m. with 40°, cooking Like chickens, you see them running around melting like ice cream. We see them and we laugh. They pay for that.
Wind, water, shade, insulation, convection, and relaxation; that's what you need to beat the heat.
Interestingly, old cottages may be the key to passive cooling. The thatched roof gives shade to the inside, and its eaves shade some of the outside of the house. They catch and keep water, letting them vaporize when its hot out, which cools the place. Green plants hanging on and covering the walls do the same thing. The tall roof allows warm air to rise and slowly go through the thatched roof, vaporizing the moisture. Mud walls, be they cob, daub, or adobe, insulate the place. That is, it catches the heat when it's warm out and releases the heat during a cold night. It also catches moisture that vaporizes when it's warm to cool the place. The walls are whitewashed outside, which reflects the heat out of the house. Small windows only have wooden shutters, which can be opened to let in the breeze and let out hot air, as well as closed to stop sunlight coming in from a particular direction. The chimney, when there's no fire, acts as a solar chimney, that is, it gets warmed up by the sun and uses convection to let the warm air inside it to rise out, which creates suction to draw air from inside the house, thus also creating a breeze within. Doors are often half doors, so the top half can be opened to let more breeze in and heat out and can be closed entirely to keep sunlight out.
Such a cottage was small, allowing a small breeze to cool more of the house, and there was only one room with no partition, allowing any breeze to flow freely inside. Flowers in the garden and in clay pots within would add a sweet scent to the breeze. The dirt floor (earthen floor) and the kitchen garden around the house would also catch and keep moisture to release as water vapour when it's warm. The breeze picks up water vapours to cool the area.
Beds were linen sacs of hay or chaff, which reflected rather than kept heat, keeping them cooler to touch. Woven rush mats laid over some of the dirt floor, which reflect heat away and kept moisture on them to vaporize easily. Stool seats and chairs were short and made of wood and rush.
Of course, it helps being barefoot, wearing flowing linen or cotton clothes, and keeping one's bedstead and seats short as the cooler air is closer to the floor
Climate shelter doesn't need to be an official designated place. It can be unofficial designated place as well, like the bar, library etc that the common people say in the video. It is actually this unofficial designated climate shelter that need to be invested by the government.
4:01 “10 degrees celcius” hotter means “18 degrees Fahrenheit” hotter. When you work with relative values, you ignore the 32.
Yeah, pretty embarrassing mistake on their turn.
Major error. No sanity check before publishing?
It's funny, people don't like the heat, they're the first to ask to cut down the trees that are blocking the view or their path on the sidewalk
I totally agree but they also pay a lot of money to go as tourists to places with a lot of heat.
We'd probably never have something like this in the US. These people actually care about their people
Winter where I live, Melbourne, but last summer when the temperature exceeded 35 Celsius, the pool I go to regularly was free.
Lots of Australians go to the malls or movies.
But none of these work on very hot nights. I'd also like to hear solutions for that.
Correct. The best first world answer is get a small room specific AC. I sleep, in my room. So I weather sealed my room and installed an AC. I have it run for 1hr and auto shut off. It quickly cools the room, removes humidity, and I sleep quickly. The room will slowly warm up but I won't notice till it's time to wake up. Saves a lot on energy. Cool yourself not the whole house.
Trees absorb a lot of carbon dioxide in the air. Also they create shade and also raise humidity in the surrounding area
It's gonna get hotter than this???
Ugh!
There must be a way to store this heat and use it in winter.
DW Planet! Is this feasible?
For two week storage cycles there is "sand battery", Polar Night Energy.
I grew-up working in a greenhouse. No environment needs more humidity; evaporative cooling contributes to a greater problem. The heat-index, or wet-bulb temperature, is greatly a measure of humidity, a situation where the temperature is high and one's perspiration evaporates slowly. When the heat-index is high, humans can't benefit from the endothermic phase-change (absorb heat energy) of liquid perspiration to water-vapor. A power outage following a tropical storm in Texas, recently took the lives of some of its most vulnerable residents in Houston. Houston is a place where evaporation rates are slow, due to low-altitudes and high humidity. Comparing similar latitudes, Houston, actually has less sun-exposure than climates in the high altitude and dry Southwestern United States, west of it.
Water-vapor is also a greenhouse gas. When pavement, soil, or buildings absorb visible light, it converts that energy into long-wave infrared radiation, which is emitted from that material both day and night. Human metabolism also is a source of infrared radiation. Atmospheric greenhouse gasses convert infrared radiation to heat energy, increasing the temperature of the atmosphere. This is why dry climates, experience lower temperatures at night, there is less an insulating-effect of humidity, as understood by the greenhouse effect. Any benefit of using vegetation for evaporative cooling is ultimately reversed by precipitation, where condensation is an exothermic reaction, increasing the temperature of the atmosphere.
Vegetation attenuates light, but, the benefits of shade is restricted to a confined space. Also, vegetation interrupts any passive-cooling performed by a natural breeze. As far as carbon sequestration is concerned, it is more complicated than it is often touted, as decomposition of vegetation works against the process of photosynthesis, and methane, an other greenhouse gas, is often associated with vegetation decomposing in anoxic environments, such as animal digestion, anoxic composts or landfills, and reservoirs or retention ponds. Introduced vegetation in the built-environment is complicated and energy intensive, with uncertain benefits, particularly when you consider the climate of the overall region, and not an isolated environment in the city or suburb.
Thank you for the thorough explanation and for taking the time to write it
People need to be educated on this.
imagine doing this in germany and everyone just complains that the free water is ohne sprudel
It seems significant that there is a gradual growing acceptance of extreme heat rather than a perception that much can be really done to prevent it.
I live very close to Barcelona, and it's mostly the lack of parks and green areas on streets. As you showed, one of the climate refuges, is a school, closed in summer most of the times, and also on weekends, or libraries... Yes, there are trees and bushes on streets to give shade, but it's not enough. Plazas are mostly asphalt traps, fountains doesn't always work (as shown), and the water of those fountains, yes, it's drinkable, but tastes very bad depending on what area of Barcelona you're in. If you go to the very center, say, Arc de Triomf, Plaça Catalunya, Las Ramblas or Plaça Universitat, that's a literal pan. People who lives in the center are mostly wealthy, and in the outskirts, like in La Prosperitat, as you showed, they can even afford ACs, people has very low incomes, and their only choice is going to a bar that has AC, or have a drink. It's the lack of political response and poor urbanistic planning, the only people who care is cooperatives like that one from neighbors for neighbors, without any help from the government or the District. When I was a kid, parks had a lot more green, but that costs money to mantain as it should. A very good example is Glories. When in 2004, the Forum was a big thing, the Glòries drum, it had a very nice park inside, and in 2010, it was demolished to make a massive asphalt zone, with a few trees here and there, not even planted on ground, but in plastic planters ugly as a sin... Barcelona was a very nice place to live, not today, sadly. Great job, I enjoyed the documentary.
This is why I don't go on holidays anymore and stay in the cooler North of EU. Nevertheless heat is here as well of course, the difference means extending my life time, being chronically battling with health issues. Yet I always wonder when the heat will trigger an ice age. And whether we already prepare for that one change as well. We are facing extremes, while longing for balanced climatic circumstances.
Lot's of solar energy available in Barcelona. It should be possible to have accessible public spaces with AC.
Of course, we are going to install them with the money we get from the tourist tax. So that the poor tourists feel more comfortable. Do you know the amount of heat generated by the outdoor unit of an A/C? If you have one check it out for yourself, the outdoor unit.
The use of passive techniques such as plants, air chimneys, and painting roofs white are very smart and very cool. (pun intended)
Is there an Instagram profile where we can see more about climate shields?
Hi Vitor! Subscribe to us here and to @dw_environment on Instagram :) We will keep you updated you over there too ✨
Paint most surfaces white.
In summers wearing white dryfit loose long sleeve shirts help a lot when you need to be outdoors in the daylight
You could try building cooling towers like they have in the Middle East? They're built right along the street to drive cooler air down toward the sidewalks. They're also built into homes & other buildings for natural cooling.
When a foreigner goes to live in a country with sun, she discovers the heat and has to make a video about it. Now at least you have A/C but before not even that and we worked the same. You see foreigners sitting eating in the sun, drinking wine, running around at 12:00 with 40°, wondering why we don't go out outside at noon, believing that we are lazy because they do not conceive in their tourist mind that we are working. Well, so you have discovered the heat and you have to live a normal life putting up with it? That's what we've been doing for centuries and we don't spend the day lying around waiting for them to do so.
Used to beat the heat with a stick. It didn't end well honestly.
Great report.
how about we get rid of big oil, as a first step

Ff is the only thing keeping the planet habitable now. 50 plus years too late
In South Korea, banks. Air-conditioned banks. Banks used to be an informal place of respite from the hot summer heat for decades, and now there are signs on bank doors that say people like the elderly can come in and "chill" without repercussion.
You won’t believe but in the Baltics we have also periods with 35 or higher under the sun and this is north of Europe. In June we had higher temperatures than in Italy or Spain or Portugal (have friends there so checked)..
Funny, they close the Barcelona heat shelter in August. ... to defeat the purpose.
Vivo en barcelona. Donde están esos refugios? Dónde puedo encontrarlos?
Hola David! Hay un mapa que muestra todos los refugio. Puedes encontrarlo aquí www.barcelona.cat/barcelona-pel-clima/ca/accions-concretes/xarxa-de-refugis-climatics
Trees really are the key to tackling the climate crisis. They modify the hydrological cycle, transpire and absorb water, control speed of run-off on hills and prevent soil erosion and flooding, create biodiversity, microclimates and habitats, moderate wind, lock up countless tonnes of carbon, provide materials and food and keep us cool. In the UK we have destroyed much of our forest cover. In Wales and Scotland vast areas have been denuded to accommodate millions of destructive, methane emitting sheep. In Wales people live in cramped houses or are homeless while millions of acres of grassland are provided for 10 million sheep (the government actually gives wealthy landowners money to do this) which can be seen luxuriating in their expansive open spaces, roaming free on ‘countryside’ to which most of the 3 million people in Wales have no access. Many people here have no land and many no garden and the towns are mostly treeless too with nowhere to walk or children to play safely
Green spaces and founains are a nice idea. They do require lots of water though so you can't really use them that much when you have a drought going on like in Barcelona at the momoent. AC and solar work better in that scenario.
It’s obvious that it is so hot in that city because there no trees. Create micro-parks as cooling centers, even if you have to tear down existing buildings to do it.
Plant more trees for our environment and make it green.
On your every birthday plant a tree 🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳Thank you
3:28 Is she filling the glasses from Toilets? Holy Cow !!!
It’s drinkable and the WC is clean. So why not?
It's nasty right! I don't even do that at home even though I know my bathroom is clean.

STOP OVER BUILDING WITH CONCRETE
Exactly. But we all know they won't stop doing that any time soon. The money is what matters for these "people".
PUBLIC LIBRARIES ARE SO UNDERATED....
2:58 Those oranges, you can just squish them, add water and sugar, and ice.
Water ain't good to drink in Barcelona. Lots of liver issues if you do. There's massive agriculture for exportation, that uses most of the available water of the country. They ask for the citizens colaboration but if things where done properly...
📌In the Philippines, the highest heat index was recorded in Guiuan, Eastern Samar on Sunday, May 26, 2024 at 55ºC.
More trees, water sprinklers on rooftops, less "on the ground" parking (rather have garages)
It's hard to get colder on summer in 2024
You messed up a little bit with Fahrenheit scale. 10 degrees Celsius hotter is not 50 °F hotter, it is 18 °F hotter. 5 °C cooler is not 41 °F cooler, it is 9 °F cooler.
In the south of Spain and other extremely hot areas in the world people has been doing that since always. And we have been classified as lazy people by the regions with better summers. Now that everywhere is getting hotter those areas with better weather do what others have been doing for decades and they call it innovation.
This summer hasnt been so cool in western and central europe for a long long time ( 10+ years )
The rest of the world at 24°: 😋🍨🍧🍦

3:25 that wasn't true up until a few years ago, I believe, we had one of the highest aerobic microorganisms concentration in water amongst spanish cities lol
Wow Barcelona 👏👏
How out covering the streets with bamboo blinds or canvas?
0:43 “Barcelona is the city many look for inspiration” - all DW videos on Barcelona claim this…
Barcelona was the worst city I’ve visited in Europe, a sea of asphalt, concrete, smell of car exhaust and heat. If you go south to Seville, which is also Spain, it has lots of parks, trees and narrow streets designed to protect you from the heat - it’s in the same country and much better than Barcelona.
Yeah they only briefly mention that at 4:00
Sorry, but there is no enough room for new big green parks, gardens, boulevards with trees, etc. in Barcelona: look at maps!
cannot believe that brazil gets up to 62 degrees
As others said, this is a misleading title. Not about regular people keeping cool, but specifically about climate shelters in one specific city.
So if you have mountains and a coast, it should be easy to regulate temperature. Make Barcelona a big Air conditioning unit. Pump water from the sea towards the mountains and let the mountainous altitude cool the water and run it down into pipes through Barcelona streets. for the size of a city like Barcelona, this should be possible. In India, there's an ancient castle in the state of Rajasthan called Hawa mahal. Temperatures in Rajasthan can easily touch 40 -45 degrees. The hawa mahal uses convection currents and smart window design to keep the interiors at least 15-25 degrees cooler depending on wind. (hawa means wind). Even Egypt had a smart way to keep their homes cool without an Ac in the hot summers.These officials from Barcelona need to take a world tour, especially in hotter countries to learn smart architecture and systems that have been in place since centuries.
The mountains close by are not high enough to have snow or be cooler
Thats an expensive way to do a simple thing. Just build internet cafe and bars in the shape of huts along the beach so people will have a windy shady place to work and rest for a small price
@@DieNibelungenliad Barcelona is a small place. It should be doable. And it's not the whole city. It's only in parts that get really hot. Satellite imagery will show the hotspots in the city.
I don't recall such a cold summer.
0:07 21° degrees, we are surviving in 45° In Pakistan that temperature is not a problem for peoples.
yes but the problem is, in other places it was designed to trap heat since in winter they get very cold and so it becomes unbearable, and plus most people aren’t used to it, but yeah in hotter countries they’d build with better AC’s and buildings that aren’t designed to trap heat
At the end Anchor left The water tap open after pouring water into her glass...
Goood morning after super . These kinds of heat shelters were always present in Türkiye . İt was under a big tree ( mostly plane trees ). Trees are the solution
I went to a "climate refuge" parc in Barcelona few days ago, and it was hot af 😆
Again put the money we pay on our buildings and isolate them better 😅
I have been living here in Barcelona in a building from the 50's with No isolation close to La Prosperitat and dude it was ultra warm and super super cold in the Kitchen (around 6 degrees on the harder days, inside!)
Why is it? It is due to really very poor isolation. That's the worst issue. Really very cheaply done buildings are 95% of the ones we live in
Also the pedestrian zone shown? It's only bricks and no trees almost. It's very badly done
😆 27° is hot. My apartment sits at 18° without heating in winter. ( Timişoara RO) Doesn't B get a sea breeze?
Third places, free, cool
Mhh its a good idea to dry the wet clothes on a rail in the room 🧐 makes the room colder… what an invention
Fact check maximum temperature in Brazil please. According to wikipedia:
56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
Per their own source in the description, Rio de Janeiro reached perceived 62 C, and actual 42 C. Mixing both and showing that figure without context is misleading.
Thanks for catching that, the temperature on screen for Brazil at 8:04 refers to the perceived temperature. The actual high was 42 C. We've added a clarification 👌
"bathroom" (American English) = toilet = wc = lavatory
24⁰ is cold in Indonesia
A ver si lo entiendo: son refugios para el calor que cierran en verano? 🤨
Algunos de ellos, como por ejemplo las escuelas
You need to remove asphalt and put green inside
Where I live some cities get to 40 degrees Celsius or more. Yet no heath deaths are reported nor there are any climate shelters. To see that Europe worries because you get to 24 degrees is hilarious.
A split system Ac is no longer and optional appliance and with power prices so is solar to power it for free.
Also reducing the number of cars will reduce the amount of heat.
I'm not drinking tap water from the bathroom of all places. Yuck. I don't even do that in my own home even though I know mine is clean
If you tested your house, you'd find your kitchen sink tap area contained way more bacteria than an area used to wash hands with soap
Heat and drought (also causing food shortages) Is what will kill 100s of millions in the next 10 years!
Maybe better for the planet on a larger scale.
@@anniestumpy9918 Is it better that we cause something that'll kill a lot of other species, not just ourselves?
