to talk about there is a significant risk of human extinction from advancing our system. our series continues to dw the d u struggles to cope with extreme heat. you're not the only one, because temperatures around the 40 degree celsius small can be deadly. according to a study conducted by the pos learning institute for global health, you're alone saw from 47008 related deaths in 2023 on ongoing climate change means that things are going to get hotter more frequently on for longer. in india, temperatures tops 50 degrees celsius and 2024, where the vast or in saudi arabia or spain. teet waves have a power lines the effect on everyday life. and i cannot make impact researches in

seville and devising solutions for making the city a cooler one. and also in this addition of made a heating system that can switch to a cooling one. why sweet and it's setting the pace when it comes to emissions plus a portable plugin power station for green energy on the go it's temperature source and the streets empty here in seville. so do the shops. bad news, especially for small retailers. committed to schools like houses that are located in the city center sales. i've always been lois from the end of june through august . they seem for the, you know, the city has put up fabric shades to protect pedestrians from the sun. but

shopkeepers also feel the heat and july and august are more low season for hotels to assess a light in the hotels. they've started developing spaces that they didn't use to eh, call such as the outdoor patios, including swimming pools, the guests, so enjoy it. okay. no, it wasn't very common in seville. 10 or 15 years ago. the a concern you one prospect for seville. this open plan space is very popular when it's just too hot outside our d a. so it is 30 degrees celsius in here for the 42 hours time. and that's a huge difference, not to be put into a but it on the building on the cities former expo grounds. it's called car to how cannot. and it's literally cool engineers from the university of seville set out to make the public space plants. and even in 40 degrees celsius heat, without simply installing giant air conditioning units, look at some will have the in the created spaces where people can feel comfortable about photo times of the day. safe,

a new system via and that'd be in which they can also use directly ation, whatever they want us to the devices are increasing the mental change and a more and more locations around the world you might have passed the of the climate change is not just about one, the city is a global issue, all the colors, the noise in the be the one of the, of the cooling works with water stored in underground tanks. the con, out system developed by ancient persians. it's used shelby here and below it through the buildings floor and walls. the cooling water even flows through the roof. and under ground, the buildings basement is full of pumps and filters. too much technology and ultimately a waste of energy voided. but it's a look. i don't know to get hold of it might seem that way. the energy that we generate with rooftop solar panels is actually mold and we need it here. it doesn't really, so it sustainable. i think it's almost up to me really of the water stored under

ground and nighttime evaporative cooling are what makes the system work. the team shows us just how during the day, the elephant when the night sky is pretty m. o. the heat is released into the yeah, the water, the drove and we storage again the what we have to last time explore the water. and by doing there about 20 degrees celsius warming that all the newer lanes and seville old town provide shelter from the summer heat. and contrast to the newer neighborhoods which are fully exposed to the sun and deserted in the afternoon. it's here, this is sonya. just want to introduce some fresh air. and it's a golfer lab last time that we chose the paving caffeinated volume. and in the future we'll have a lot of change on the lease and the treatment that we just planted, i had the feeling for the loss of. i don't know, it will be a kind of giant power so that will adjust itself to the vegetation and by that shortly, it allow you that we also have

a bio classic finishes the name most. oh. and then we have a series of live in the low out code, and that's really that he can vote as i later for you. this also uses the cannot technology and has a fountain design to block hot wind and cool the air at the same time level have been it'll tell me, hey, will be a rest area and on, and then go to treatment data will reduce the temperature for by 10 degrees celsius i will feel the same while i'm in the square was supposed to be fully functional this summer that was delayed by an error in the proposal, which is also affected. the teams latest project, a cooling bus stop. it's worked so far as a land prototype with its rainwater base cooling circuit and solar powered pumps. pitch should be sustainable. bus dumps play a key role during heat waves. the kalama items we install them throughout the city on of a heat shelter networks. recent studies have shown just to urgently needed such

cooling spaces are hotter weather costs as taurus to spend less money or stay away altogether. a problem in the future say tourism experts to let the temperatures keep rising to a school things. why it's about traveling further on under. we see it on places like most. yeah. or extra. not do it right there, my buddha. it'll be a challenge from just like it's already a challenge to travel to central america as when we complete the eat. i didn't video or the regular the researchers, findings and innovations and seville are available to the public as they're not patented. the teams priorities to ensure that people can actively enjoy life and the heat on a hot day, funds can be a real blessing. do you have enough at home? how about air conditioning systems except the real power goes unless on don't

exactly score high on the environmental front. how about introducing cool air into buildings? all know that you taishan or turning the tables with heating systems that can work in reverse. the sun is blazing deep wakes with temperatures of over 30 degrees celsius, are becoming increasingly common in germany. it makes one variable conditions, especially in older buildings, and in the attic apartments like stephanie bellows for her climate change is happening at home. and the doctor is just wondering what out my apartment is right under the roof, and it's unbearable that time i just will push when now have really long periods where it's sometimes around 36 degrees in sign on to target and have a show effect. so sleeping is next to impossible. as a flock of seo fest lucas, it's even worse due to construction work on the doorstep. modern feels thermal heating system is being installed to cool apartments during the summer. this

machine is drilling 100 meters below the surface, long pipes cold probes will be inserted into the boar holes. a mixture of water, an empty freeze known as brine will flow through them during winter. a heat pump in the basement will extract heat from the liquid and use it to warm the apartment block. conventional heat pump technology was developed further so that it can be used for cooling in summer. without pleasure, will cook ground is always cooler than the inside of a building and this week i'm not. so let me also circulate brian by these products, and sometimes it's going to work with young, disclose the floor, and the heat from the building can be transported into the bowl. drama, almost in the border can be stored for the coming winter for regeneration, so to speak. if you can or to and i can dispose of the welding things to the heat that stored in the ground during the summer. the pump functions more effectively than conventional systems during the winter,

apart from the heat pump in the pipes in the basement, the old system didn't have to be changed. it led to huge cost saving, says bella humbles from a housing association in the eastern city of live sick. he had the new system installed in the apartment block with around 100 homes. the spent around half a 1000000 euros. his initial assessment is that it's already paying off the vision . i think we expect to lo uh, heating costs for around 50 percent of your tenants can also have cooler homes in the central enough to do and beaten. couldn't stephanie miller has received a new radiator valves for her apartment. during summer time, she sets them to cool the radiators react immediately. she says it's worked well in the recent weeks. as i had it in, i have the impression that it worked this summer. and then when i touched the radiologist as i felt the wind nice and cool,

the city has come of unction crew. and it was pleasant in the apartment thermal energy expert on v comcast says that technology can be used anywhere where people suffer from too much heat in the summer. the adapting to climate change on shielding ourselves from the heat is certainly sensible. we also need to put the brakes on global warming, but lowering carbon dioxide emissions is proving problematic. the international energy outlook report full cost of the 15 percent rise in energy related c o. 2 output by 2050 a huge challenge with the energy sector alone. the biggest greenhouse gas pollutants, but showing the world that there are other options is sweet in the country has a decades old climate friendly energy policy,

which has produced some pretty remarkable results. when i say sweden, you most probably think of ikea about ends think you can fish of the country actually pulls off another remarkable seat that deserves more attention. the best performer in your way comes to reusing, we don't need to reduce welfare to reduce your traffic impact. that is a message to the wall that's so important. and that's what all they set themselves, the world's toughest climate target, and on track to meet it. so what us to be doing better than others. let's take a look at how it became a role model on climate and what other countries come to and from the success story we even have some natural advantages. i mean, just look at all of that last green, forest, 70 percent of sweetness, forest, land, and forest. a very useful when it comes to reducing greenhouse gas emissions

because they remove c o 2 from the atmosphere. the country is also blessed with a lot of wind. just look at the long coastline and then the all these big lakes, perfect for hydro power. but it wasn't just shooting the natural resources. jack product that got the country to where it is now. it's being realized, it's natural potentially early on, instead of investing and renewable energy sources much earlier than many other countries. we just started very early to come out fossil fuels from our energy mix. this started already in seventy's when sweet of built out new care coordinates . back then the global oil crisis said in countries we're looking for other sources of energy that's, that's up to a speedo to cut out for you from our energy mix. today almost 70 percent of students. electricity comes from renewables, especially hydropower and wind. the rest of the electricity demand is met by nuclear power. we have gotten emissions on the electricity pollution. i was 0 right

now. so the, i almost not using any fossil fuels for using electricity. what's most stunning though is that speed in minutes to clean up its act was also growing its economy. and all of this and having the industrialized country, which makes steel cement and cars. it's this combination of innovative climate and industrial policy that's, that's been a part the reason doesn't just get rid of fossil fuels and the electricity production, but also when it comes to providing heat for buildings and industrial processes. and that's quite special for a whole country. so what was the trick there? the 1st step was that's being invested in district heating systems early on, which is more efficient. this means that instead of having a heated edition, you build big central. i have heaters that are connected to lots of houses and industrial areas through insulated pipes. and my current infrastructure is quite a big undertaking. your needs, the government and the private sector to work together to provide this

infrastructure. it's also quite expensive. just think of all the piping you need to lay across and try unable. that's not the less the government decided to go for this approach early on and start with that. and in the past 20 years, heat pumps have also become very popular in speed. have you anywhere else in europe? i did use as much per capita as speed. when more than half of all residential houses have installed them. these kind of work like a reversed ac ends, they run the electricity and the rates step through the last 30 years. the emissions from electricity and cheating, which is often a difficult sector for many countries, suite amount us to reduce emissions by 70 percent in 30 years time. so that also shows the big, big, bold changes are possible. and these big bull changes didn't come out of some air speed and is implemented kind of policy since the 1990,

such as introducing one of the world's 1st. and by now, one of google's highest carbon texas, charging industries and individuals for the carbon dioxide damage. when the actual stress discussed it really on became a through wine agreement that this is 2 ways more and as, as, as we know, there's not a single party in space part of the human question to call it a 20 men team. empirical case studies found up to speed of carbon tax had a single, it's like an impact on c o. 2 emissions. it was responsible for 6 percent decline of emissions sometimes. but in an average year, there's a to your message was either we do something that's bad for you and we have to pay to fax. what do we do? something that's better. i went all next. and the carbon tax spark innovation. but for the students industry, i had almost 10 percent of sweden's clement name that comes from the steel industry because it's used as far fuels but suite in the ames to become the ones 1st in producing large quantities of full size, free steel using green hydrogen instead of fossil fuels and vicious and my rent and

policy has been, uh, uh, increasing speed is competitiveness. this also translates to the way speed is investing. it's future as quite large focus being the schools in educational system on engineering, and on scientific state. and all of these, and we see for example, the squeezes is quite a little bit squeaky when it comes to song specifics specific as a whole title, renewable energy. and while in many countries, the public with revolt against any new tax acceptance and speeding has been high. and this is true across the political spectrum. 7 out of 8 parties agreed on the world's most stringent climate target and 2017 are ready to be met. 0 by 2045. so it really seems like speed on concept of what's wrong when it comes to kind of policy. or can they? well, yes, i could, culture is one second. what has been little to no progress when it comes to reducing emissions? but the country's biggest problem, child is the transport sector. that's what most of students emissions currently

come from. and as an important sector, after all, speed in may not have many people, but it's a country of long distance us. but the spies and bushes targets progressive, so we are expecting to see increased emissions again from the transport sector. for years, sweden had been introducing incentives to reduce transport emissions without the state having to pay for the trends. thousands, we know over the years if box and electrical biomass cards, you will be given a bonus by the government. but if you chose to still have or to buy a new gas guzzling as you read you, what is the pay an extra the x? and so the money given to the best cars was paid for by the money coming from the worst cars. but lately sweden seems to be, i'm doing some of these successes specifically in the trends, but sector speed, there's no conservative government which came into po on september 2022 has rolled back some important policies in light of freezing crises. it has lowered patch one

diesel, texas by a quarter, which means to be now has the modem, lowest price of diesel and gasoline in europe. it also introduced other measures that make it less expensive to drive the car, while abolishing the incentives that were previously offered to buy electric vehicles. on the bright side, the government also promised that these new metro's will only be short term and will be lifted again as soon as speeds economy kicks back up. so yeah, speeding as an almost perfect drone model in terms of time of policy. i think industries that yes, it's indeed possible to produce electricity went out and i think we have got some issues at all. and it's maybe it's all for the countries in what speed has experience can also show that a pace often the long run when the state introduces tough time and policies that will give me the green businesses, degree and job, to be honest and explain income. but you can use side of things that you are very well for a bit of schooling as only for and this can only work if all of society is on board the are you also learned about machines one

day taking over, but not just odd jobs, but our lives, the stuff of science fiction for now. what is already clear is that onto visual intelligence with it's awesome. computing pilot is boosting productivity. but how about using i for the fight against climate change and making it a create the can a, i saves the climate the lawn mower style. i'm sure the car won't go. factories grinds to a halt. that could happen if t i decides what's climate friendly and what isn't. as long as it does, what artificial intelligence does best calculate everything? exactly. yeah, i could react to c o 2 emissions in real time, for example, by stopping cars when air quality drops. how would that work? a i could use data contained in households appliances,

like coffee makers and dish washers to measure c o. 2 emissions. when emissions dropped below a pre determined to limit everything starts working again. you can even ask a i how much longer the dishwasher will be on a. i could also manage other environmental problems like the rowing mountains of garbage and textile waste. energy production would benefit as well. the advantage. everything would be based on hard data taking climate action out of the hands of government the but that would be disadvantages to a i would have to collect a meant amounts of our data threatening personal privacy. i don't know now and to process all that data itself, we can require huge amounts of energy and that would increase c o 2 emissions dramatically. digital systems and data centers already consume 4 percent of the world's electricity. that number rises to each percent when we include all of our

devices. hey, i would increase that many times over. but even if there were big advancements in green a i, there would still be a problem for a i to save the climate. every country on earth would have to participate, and that would bring us back to politics the of the reassuring sound of the good old diesel generator. our trusty friend, when there's a power outage which can be critical in hospitals. but for all that crisis proof credentials, the serious noise on the air pollutants in the air of climate change, not exact the flavor of the day. but if you're out camping or somewhere else with no power available, there is now an environmentally friendly alternative. the

this cool little video is actually an ad for portable battery power packs used to places like music festivals. greek for impromptu job involving power tools for jet military. they look pretty good. that looks much. um, on the lights, the lights, but it's enough that you can. there's one person pick them up, put them in the backpack the vehicles by gate and take them to the next job. the leon ha, device construction company in south west germany uses the instagram power packs for welding work on steel girders instead of diesel generators. this workers math only needs to protect him from flying sparks, but not 30 cubes. the batteries both up to 90 percent lower emissions. the company already has around $300.00 power packs and use on it's building sites for welding

jobs, the battery is good for a full 12 hours visit. we just dig in the bill. besides, we saw it as an alternative to existing power units. maybe we'll just have it all by the here. and we want that our staff to have an additional option. i thought smoke taking, we've left the noise on site on a better work environment to the voice mail. suppose to listen on with no emissions and the direct vicinity. kind of, i've got the vincent alternative product to classic is how it generates the set some taxes. it's almost like a buy one. the batteries are being increasingly used for ambulances and other mobile work settings. their maker against a grid was founded in the south west german city of looked exports in 2018. the company now has a 170 strong and very international workforce is the developing and surfacing the high performance batteries. inputs if it says offline the both of these questions we're going to pause essentially it's a power station i've seen in everyday life. physical accounting for example, buddhist is good at email except that this device has been optimized for industry

customers on so i need a very high capacity. and so licensed phase tech call from the document digging deep into a bag of tricks to develop our own power electronics license electronic and our focus on construct did as a single unit, took off cobalt speaking last time. instead, we divided the device into $24.00 small units, each with one small battery pack on a small input to find in data. and those 24 and voters are then connected via real fast controller and a complex piece of software to work as a unit. so as i'm focusing on instagram has sold almost $30000.00 packs to customers in europe and the us with demand continuing to rise despite a price tag of around $3.00 and a half 1000 bureaus. escape, you know, also don't want to democracy. there are a lot of challenges. we worked out that around $60000000.00 small combustion generators hit the market every year. not including cost of this for the on. we have a long way to go until we've replaced all of the pump, isn't before one idea would be to create devices that are cheaper and that can be

connected to provide grades of flexibility for construction firms. there's also the issue of recharging. another thing diesel generators have traditionally been used for the career, so it's probably the biggest challenge now. science right now is infrastructure tool. where do we get the power from to recharge? the instagram? how gotten the open sonoma right now? i can cover a certain period of time time of the day, but after that i need another power source of money. get a tough thing. saladas. one option is solar power modules, except they're also not available on the changing construction sites, which is also an issue at the secret garden party festival. which is why they still need diesel generators to charge the batteries. ideally, they have against the grids with a higher and longer capacity, not least was supposed to be, but he's continuing to long into the nice this
