and sean slat has again ruled out sending germany's advance towards miss alt to ukraine in a heated q and a session and signs. a gentleman called him and he said, no taurus miss alt will be getting to key without jim control, claiming it was too dangerous that we have time for thanks so much for. can you tell me the floating away when it's 40 degrees celsius and the shade can be deadly during times of climate change? i asked wherever, what was the most difficult part of their job. uniformly, they spoke about she being the most difficult part of their jobs. men described it as a feeling of drowning and seats sky was melting,

and you couldn't read. how do rising temperatures change from different parts of the world? in fennel, march 15th on dw, the from delhi to east angle to los angeles. evolution is a big issue, especially in the world's biggest cities, between decrees or long function, it will increase. that's not that it's an increase of space in the emissions country due to 7000000. there's a u. c o, these pink dumps. they show that it almost every major city in the world. the air is found that he has some of the world health organization consider safe. when we don't into the data though, we found some surprisingly good news. in many megacities see here it's getting better. so we wondered, what are the city is doing, right? and this can be placed through this.

the, for this analysis, we looked at one measure of evolution, that's everywhere. p m 2 point 5, pm, 2.5. be able to find 5 pm, 2.5 into concise. p. m stands for particulate matter and make sure of studied particles and liquids dropped instead of $2.00 microns for less, much smaller than a human here. this is only one possible type of information about people's lives. if he could meet from the w h o, use it as an indicator for evolution in general to this is important that can come from very different sources. and because it needs to be, gets us into work. so there is really no place is the will, that is the 3 of those are to get his mentor and it's big cities that are often particularly polluted. this problem has been well known for years to sign up with anything has changed. we took a closer look at this state domains from the switch company i q,

and we chose average levels of pm 2.5 for more than 7000 cities. over the past 5 years, we put it all into a big excel spreadsheet and check that against a list of the world's biggest cities. those has more than 10000000 people living in them. of those 25 cities, it seems like the air has gotten better in all of that. even when levels are still high. what we've seen is that on average, about 5 percent improvement in air quality over the past few years. so we chase help cities that want to tackle the acquisition problems. the causes are similar even when the proportions, very transportation emissions are often number one, not always but. and then also just generally electricity use people, cooking with solid fuels in their homes and some parts of the world heating was solid fuels. another major source of air pollution is from industrial sources and then also from weight. so here's what city is that doing to tackle these issues for many cities, changing how people move around just can make

a big difference here. so if you could me from the w h o again, there was a need to be a push to really have peter peter rachels, but also fewer legal reading for more working side team. and the, providing us of the big transportation was effectively the electric. they just take bind coke, for instance. the city is working on expanding its still limited sky train and metro surfaces. and in the meantime, electric alternatives full of the traditional combustion engine trucks that keep looking around the emission fee as well. denny is working on an extra fine, 80 percent of his bus rates and even in coca, sometimes called the diesel capital of the world. a tentative psych visit electric scooter services starting up the next steps. so which i says can be introducing so called low emissions on cities that are restricting emissions in a certain part of their city votes to improve air quality, but also to improve quality of life. this might mean only allowing clean

a cars to into or no cars at all. and it might mean transforming speeds to make more room for pedestrians or by sickness. this is something that's resonating across all regions of the world right now. it's really exciting from times square in new york city, being competitive with this through an area to reducing traffic uncomfortable or being a verizon thing to more by claims. and parents are putting cities everywhere, experimenting with a different kind of urban design. transport is not the only areas such as must tackle. there is extra time against air pollution also focuses on industry and measuring and reducing the dust from construction sites and having more industry shift to clean up fuels and more efficient techniques that converging traditional bank accounts to 6 accounts. this is something a lot of cities are doing like here in the heart process done. the method still uses cold, but much less of it and attracts more of the particular meta inside the account, knowing it's emissions. one reason for dennis luxury, but yeah, the space might be that in 2018,

the city shut down the by the poor coal tall trend, which wasn't comfortable for around 10 percent of the city's particular meta air pollution on known one area that progresses still snow is waste, so they don't have you solid waste management vinyl for 201615 north implemented. every country has been advocating for clean air for more than 20 years. she found that the mother is active as group worry, a moms who campaign against air pollution by petitioning the government and courts throughout india. she says, even in the right policies of that, the governments often doesn't follow through. we do not segregate the ways to source, and mostly it's all makes and that is what is making those huge landfills and the mixed race to insinuated in the middle of a city without organized waste connection. burning is awesome. the only option for getting rid of unwanted materials causing toxic smoke full of handful particulate matter that can stretch for miles. so preventing waste as well as collecting and disposing of it better has to be part of any city's time to curve and pollution.

when policies are implemented thoroughly that can have a big impact take facing, for instance, a decade ago, it consistently made headlines for its toxic smoke cover. but in the last few years, it has massively produced it's pollution levels. and it's not just basing many of china's mega cities have improved locked recently. this is the result of what the chinese government called a war on air pollution that focused on all of the causes we've already mentioned, but not least on energy and how people cooks and heat the homes. the city of phasing impulse type limits on emissions from boy that's used in people's homes and subsidized anyone who wanted to upgrade that coal fired boiler to natural gas, which is still a fossil fuels, but produces much less particulate matter or to electricity which could be produced by renewables, studies show that 20 percent of the reduction invasions pollution just came from renovating these cold pile, going us outside of china as well. countries around the world are investing in renewable energy, phasing out coal from the energy supply in favor of solar, wind,

and other countries like poland are also getting rid of the coal and wood fired stones. and so in south korea, which already swept coal, he does for gas. back in the 19 ninety's is known as causing the switch to more eco friendly heat funds for cooking stove plants with wood or kerosene activity on the option in many parts of the world, especially in rural areas, without access to electricity. such projects from pakistan to rhonda to the millions or introducing cleanest of models to those regions as well. whether and how 5 cities can implement change comes down to a few things. and the 1st total is bit of data. take the horn and pack of some irregular the tops list of the world's most polluted cities. according to the data, it looks like it has improved at least a little. but it's hard to say without any actual changes happened. we haven't really seen any trends that would explain why the numbers are going down. so i

think it's just that the, the quality or data and prove that beat. on march 2016, he found as a pockets on equity initiative, which is a community initiative, a life i ended up individuals. corporations, organizations have come together with low cost monitors and providing that data. a public lea uh on the internet on base that farms and that data is what is driving awareness impacts on. there are very few equities you wanted to set up by the government. this makes it hard to judge with that. things are actually getting better thanks to initiative. so there are no more than a dozen sensors in the for a long showing the current air pollution levels. michigan, honda for governments and citizens take northeast and the time monitoring systems have sprung up everywhere in the past 10 years. cities are increasing their ability to monitor their air quality and this is something that is extremely important. a very positive trends from our perspective. then that's the question of money

changing was able to put a huge amount of investment into the air quality problem. and that is the key question for a lot of other cities right now. do they have the money to invest, to make such a step change in their air quality? and last but not least, physical digital collaborations. so if you imagine air flowing together over parts of the world, that's what we call in the air shot and it doesn't respect political boundaries and found a place like daily. it's extremely important but neighboring cities and jurisdictions work together on their common problems. cups of, of learning brings in 10 small to now that india, including daily every year after the harvest season. and the same problem happens, for example, in cairo or across indonesia where smoke cells can reach so far, they affect the air and singapore and parts of malaysia. so cities, regions, and countries will have to work together to change. because of what we have at the heart of the matter is the health of the people living in

a city. it doesn't really matter where the air pollution is coming from. it's extremely important that it's reduced. so evolution is still a huge issue. big cities all over the world are pretty far from what the w h l consider safe, which would be below 5 microphones per cubic meter of it. but it's can get better. so that's a, the people that they get this a discipline does to fix it's, it's taking me a decade, 0 for us. people like us to be fighting the field and the gods coming with such a long re changes happens. so there's some changes in the v and even when really good air as far away, any change helps in the reduction in air. air pollution is good for any small reduction is good. what's more is that the things that clean up there are also good for combating climate change, which is likewise fueled by emissions from burning waste and fossil fuels. what would you like your city to do to pin up your yeah, let us know in the comments and subscribe to channels from over the effect this
