the air pollution we're talking about from a public health perspective is the air pollution that you: nitrogen dioxide, the main source of which is diesel cars. and particulates, those fine particulates that you can breathe deep into your lungs. in the short—term, we're talking about eyes, nose and throat irritation, primarily. long term, more serious consequences. 0n the heart, on lungs, and other conditions as well. traffic pollution on hafodyrynys road is recorded by this monitor. just a week after we started filming in january, the road breached its legal pollution limit for the whole year. neil and dawn's lives are spent indoors. they spend most of their time on the ground floor of their house, below road level. it's easier to breathe down here than what it is upstairs. dawn is disabled, and neil's her main carer. you might remember that one. oh, yeah, i rememberthat. in the 70 years dawn's lived here, she's seen a lot of changes. we've always lived here, you know. and my mam, when she was small, she used to play hopscotch on the main road. dawn remembers crumlin‘s industrial pa

which part here is the air quality sensor? this one is the air quality sensor.ific cell attuned to a specific type of chemical. this a ozone, this is a sulphur dioxide sensor. there's a carbon monoxide sensor. there's the hydrogen suphide aensor. nitrogen dioxide sensor and there's a token reducing gases. installation of the array began towards the end of 2016. by the end of 2018, 500 nodes are planned for the network, spread across different parts of the city. charlie catlett is the array of things project lead. he took me on a whistlestop tour of some of the city's earlier sensor sites. so, charlie, this is the site of one of your first sensors, isn't it, one of your first nodes? this is one of the first six. this one here does the air quality, notjust the general air quality but this one will tell us seven different gases and so that means we can say, well, this one is reading this gas particularly high and we know that that that is associated with a diesel truck. the new ones that we are putting in, we have added a new sensor for particles. what we can do wi

clearly, there is a broad air quality problem.ite ‘severe cuts‘ in budgets, air quality management ‘remains a high priority‘ for councils. they also said the onus for reducing air pollution levels does not solely rest with them, and that consumers, industry and governments all have a role to play. pollution isn‘t just a problem for wales. across the world, it‘s becoming an increasing concern, and it‘s something cities across europe are waking up to. in london, new mayor sadiq khan has doubled spending on the problem to £875m, bringing in electric buses, more charging points for electric cars, and trying to get older diesel cars off the streets. you‘re covered in, like, oily grease, when you wipe your face, but you do see a lot of people walking up here with masks, so obviously, there is some impact on all of us. whenever you cough or sneeze, you know you've had some horrible black dust in you, so i think it's pretty shocking. i'm from scotland, where we actually have clean air, so there's a noticeable difference. i caught up with

the air quality in towns and cities isa the air quality in towns and cities is a huge problem.ive in bath, a cyclist and a taxi driver, to carry around one of these. to find out who is breathing in the west air. first the taxi driver, he will carry an air quality monitor in his cap for the next ten days and does not expect the results to be good. what you think aboutair the results to be good. what you think about air quality? in bath it is not very good. some people in this city cannot breathe proper air. and he is not wrong. we record high levels of small particles found in diesel fumes. 0n levels of small particles found in diesel fumes. on one occasion as high as those measured in beijing. why are they bad, well particular matter is small enough to go through oui’ matter is small enough to go through our noses and into our lungs where it can cause respiratory complaints. another particle is even smaller and can go through the lungs into the bloodstream and has been shown to be associated not just with bloodstream and has been shown to be associated notjust with respiratory

we like clean air, so go make clean air. that is not how you should do business. because congress should be directing agencies in the executive branch and every area, finance, health care, the environment to say, here is the framework that you have. co2 issue is great example of that. when you look at carbon issue. we have supreme court case in 2007, mast versus epa. . . address this issue called carbon. because as you look at the clean air act, if anything was that it did deal with regional air pollutants. it was not set up to do at this global phenomenon that we talk about. this is an important issue that you've raised on where the balance is between delegation and agencies at the federal level acting. the executive branch exists to enforce the law passed by the legislative branch. at the legislative branch is not doing his job, a job, it creates assumption come uncertainty and way to address that with respect to very important issues. >> we do have an executive right now it seems to be focused on doing things to executive orders and unilateral executive action.

cool air to the north, warm air pooled over us. starting in the 50s.now at 6:00 a.m. the front starts to slip by 4:00 in the afternoon. now we have the colder air spilling into the northern zones and it's forcing the warmer air farther south. on top of that, as it continues to drop south, the cold front gets stuck, meaning our winds start to filter in from the east. with an east flow, it's very hard for temperatures to pick up at all. sunday we start in the low 40s. that's about where we stay the rest of the day. the cool air sits, the winds continue, and we'll notice a much cooler sunday. on top of that, your hour by hour forecast. 6:30 in the morning, clouds. 1:00 in the afternoon. some spotty light rain to the northern zones. into the evening. 8:00 to 10:30 at night. scattered light rain showers passing through. wilmington, philly, trenton, stretching even to the shore. spotty and light activity, though. it's not a downpour for huge thunderstorm activity. it's just showers moving by. they linger into the sunday morning, especially areas north of the

make no mistake, your air force is always there. however, being always there comes at a cost to equipment, infrastructure and most importantly, our airmen. we are now at a decision point. sustained global commitment and recent funding cuts affecting capacity and capabilities for a full spectrum fight against a near peer adversary. upcoming surge of mandatory retirement of an increasing market of global commerce is causing civilian industry to begin hiring at unprecedented rates. this confluence of circumstances has birthed a national air crew crisis. it is a result of multiple factors. high operational tempo over 26 years. demand for our pilots from the commercial industry and cultural issues which affect the quality of life for our service airmen. the total force including our active guard and reserve components were short 1,000 pilots across all mission areas. it should be noted that the cost to train a fifth generation fighter pilot to prepare him or her for their first operational quad are on is approximately $11 million. a 1200

then the air guard units at charleston air force base and them totarted using land others, so they wentay beyond what they were initially designed for. they asked us to specifications for other landing lights. >> this gives us a 60-degree field of view, where what normally happens is a 17 to 20-degree view. this is a 60-degree field of view. instead of an expensive piece of technology that looks around all like a bug'shave eye where it is strapped down and is much cheaper to produce. the air force can use something like this when we have a gps denied environment. a lot of technology back in the 1980's and 1990's was gps focus, and we figured out someone might be able to jam our technology, so we needed a way to circumvent that issue, and by doing this, we can compare data and put the metadata behind it in order to navigate. basically, having this wide field of view gives us the a movingo not have part. what normally to move around like our eye does . this can see the entire scene at one time. the wide field of view basically reduces cost and reduces our technological complexity in order

cold air in place. reason jet stream has taken another shift, southward, it has been like this all winter long. we will get warm up, another cold shot of air. there is arctic air bottled up in canada. good snow pack here. that colds air is moving southward so temperatures running 10 degrees below average. it will feel more like mid to late january. tonight even colder, it could be coldest night since early january of this year. not much happening today those that is good news. if you are traveling today you don't to have worry about those intense snow squals, maybe mountains of the central pennsylvania, upstate new york we will find those snow showers but majority of the delaware valley stays dry. a lot of sunshine and high pressure least mains in control. this blocks any storms from developing throughout the weekend. we have got sun going for us today but still we will struggle to get to the upper 30's for actual daytime high temperatures. sunday looks good but still on the cold side, and it will be le

that will be a good surge of cold air for the weekend and probably the coldest air over one month. it will come and ride along the arctic cold front that will pass through tomorrow morning and it will be springlike today. by the time you wake up tomorrow morning, there will be rain and snow showers for your friday morning commute. the arctic last sticks around for the weekend and into next week and it will be cold enough that we have to watch another weather system monday and tuesday that could possibly bring the possibility of snow accumulation. this transition, in futurecast, the rest of this afternoon and the evening plans, they will be gorgeous outside but after midnight, we start to see clouds increase and the rain and snow showers come with falling temperatures as the cold front tracks in. 5:00 a.m. friday morning, place of north -- places north of town will have rain showers mixed with verse of snow. probably seeping into the metro as we get to 7:00 and 8:00 tomorrow morning. i want to point out the temperatures. 38 in dc, and in places like frederick, the air temperatures w

, a very dry air mass currently. the pressure is rising. the winds are light. that's going to change with the coastal storm. the ocean temperature is key. as the low pressure draws near the coast it will bring in warmer air. that's why the numbers are lower in south jersey and delaware. if we get the warmer air in philadelphia it will cut down on the numbers a little bit. satellite and radar showing we start with sunshine today and then we bring the clouds in, turns cloudy later on. we have two areas to low pressure, one to the northwest you can see the spin out there. one to the south. they don't exactly merge, but the transfers its energy to the coastal low that will enhance the storm totals here. we start with sunshine stay behind clouds, it's a cold day today, 36. it's a dry day, the winds are not terrible, all that changes later tonight. let's go to future tracker 11:30 p.m. the first flakes start to arrive and watch closely the rain sleet line that will compact the totals. we advance this to 4:00 a.m. we're goi

that warmer air is coming in. we still have the very cold air around and temperatures right now range near the teens and 20s in new england while we're in the low 30s in town, but columbus is 53 at this hour. so on the other side of th mountains the warmer air and that warmer air will move in a little bit tonight but more so tomorrow. so tonight it will be cold. some spots will be down in the lower 20s like frederick and gaithersburg and manassas while we'll be in the upper 20s, around 30 in town and in annapolis probably lower 30s. on futurecast tomorrow we're looking at kind of a mix and clouds. i'm thinking thicker cloudiness in the afternoon. by lunchtime we'll be near 50 which is a good almost 10 degrees warmer than today. as we get into the afternoon, mid-50s should do it, might see a shower monday nitrogenly north of washington, but tuesday -- night generally north of washington, but tuesday we'll be temps into the 60s with a chance of late afternoon and nighttime showers and after that a front goes through

that's cold air just starting to move in. the coldest air isn't here just yet. the winds, though they won't be as strong this afternoon, they'll still be with us. that will be the colder air that keeps coming in during the day that's going to lead to temperatures pretty much going nowhere. 47 degrees in lehigh valley. the temperatures will be coming down in the short term. 8:00 with some clouds blowing through. 41 degrees. and then down to 40 degrees, in spite of more sunshine later in the morning. it's the wind that's really going to hold the temperatures back. 50 degrees right now in philadelphia. in midnight, it was in the low 60s. winds out of the west at 24 miles an hour. down to 45 at 8:00, at 11:00 this morning, philadelphia, 44, those winds will still be present and sunshine will be nice and bright but not looking for a big warmup this afternoon. in fact, much of the area will be cooler than where it is right now. sunshine, windy, 49 degrees in philadelphia. 40s across the board including the jersey shore. the wind will be dying down and older air moving

there's the mild air. chicago, 40's and 50's this hour, that will spread eastward over the next 12, 24 hours. the sign of the warmer air is going to be clouds that you'll notice tomorrow. filtering on in from west to east from the morning to the afternoon. there's the warm front still to the south and morning hour, by monday afternoon, you start feeling the different and on tuesday we'll warm you mean. but there will be rain showers. tuesday afternoon, night. doesn't look like a big severe threat. maybe a half inch or less of rain. that's good news, we can use more moisture and temperatures into the 60's by tuesday. like i said, that cold air hanging around monday morning, waking up back to work and school. low 20's and a lot of the suburbs maybe upper teens in some of the coldest spots, 30 in philadelphia. we bring the milder air tomorrow, i think areas hit the low 50's for afternoon highs on monday, check this out. tuesday afternoon, south winds overtake the region well into the 60's, mid maybe upper 60'

all this week we will be focusing on air pollution. it is pa rt focusing on air pollution. i can breathe. the world health organisation, margaret chan has been talking to the bbc as part of that and external white olivers in whichever concha beuran need to take this issue seriously. our pollution is one of the most pernicious threats to health because it is so pervasive and because you cannot escape it. everybody has to breathe. when breathing becomes deadly, the entire city, it doesn't matter which party and it becomes hazardous to health. that eric and travel for hundreds of kilometres b and a city to endanger health and surrounding areas. this is a big problem. let's concentrate on moves to make london's black cabs more environmentally friendly. the taxes you see here are running diesel engines, but the firm that makes them is introducing an electric model. in a move i didn't anticipate it is testing the taxis in arctic norway. on some of the coldest roads on earth, in some of the cleanest air, secret tests are going on. for a vehicle that could help cut pollution thousa

i would not call the air quality good, i would call it average.ir tag. this is reading carbon monoxide. it is giving us concentrations that appear to be a little above 1.5 ppm, which i would say is very consistent with what we are seeing in the nitrogen dioxide. it is giving as a moderate level of traffic pollution as we might expect. i think that in a sense is a more predictable sensor than the ones depending on volatile organic compounds because that is a very big range of substances and the sensitivity will not be the same for every compound. now the next device we are looking at is the i—blades phone case. i noticed this one set a baseline for whenever you open the app. so when we opened it here on this street it is calling this streak zero, which seems a bit of a funny way to work, doesn't it? i think it is, yes. so, ideally it needs to be zeroed in the very clean atmosphere, but if you do not have an independent monitor, how do you know where that clean atmosphere is? i think we have a bit of a difficulty with this one. our final device that

colder air has moved in.ratures dropped to the 40s and pretty much stay there the rest of the day. the cold air will stay because the cold front kind of gets stucks right to our south. that holds the cool air in place. hour by hour forecast, also we have some rain to deal with as this moves through. that's the energy we need for a few showers to pass by. this morning very isolated, spotty areas of rain. drizzle areas. 2:00, same deal. not a lot. a few sprinkles. most of us are kind of cloudy with peeks of sun trying to break through as we go along through the day. into the evening, like the front i just showed you, 6:00 or 7:00, starting to creep in. we could see more spotty showers. again, it's not heavy rain or widespread. it's spotty and light and continues into sunday morning as well. 6:00 a.m. mostly north and west of philly. you see the pink over parts of the poconos. could see some freezing rain there. this is just an inconvenience type of rain you might run into on sunday morning. a break during the d

i wouldn't call the air quality good, i'd call it average.rbon monoxide. it is giving us concentrations that appeared to be a little bit above 1.5 parts per million. that would be consistent with what we are seeing in the nitrogen dioxide. a moderate level of traffic pollution, as we might expect. that in a sense is a more predictable sense than the ones depending on the volatile organic compounds because that is a big range of substances and the sensitivity will not be the same for every compound. then we are looking at the i—blades phone case. i noticed that this one sets a baseline for wherever you open the app so the fact that we opened it here on this street, it's calling this street zero which is a funny way to work. i think it is, yes. ideally it needs to be zeroed in a very clean atmosphere but if you don't have an independent monitor, how do you know where the clean atmosphere is? i do have a bit of difficulty with this one. 0urfinal device is flow by plume. this is the prototype, the final version will look similar. it syncs up to a

we were fired upon from the coalition air force. the snipers go to the top of builds that have families and the air force strikes these buildings killing them and everyone in the house. >> now, ivan, both iraqi and u.s. military officials say that this isn't going to slow down the operation despite the calls from some local provencial leaders to do so. the u.s. military also reiterating that their goal is zero civilian casualties. we know that is nearly impossible. >> that's been one of the enormous challenges of trying to uproot isis from mosul. it is a densely populated city with hundreds of thousands of civilians there. you can't just simply flatten the place, because you will hurt so many innocent people. it is hard to imagine a potentially worse or more horrific situation for the civilians trapped in the middle of this awful and grinding urban conflict, ian. >> that's right. specially when you look at where they are fighting right now in western mosul in the old city. this is an area with old buildings, narrow alleyways, densel

year to the north when you clash such cold air with such warm air, and we have strong winds, it's reallymp up this system late tonight and as we look at the temperature profile overnight at 1:00 in the morning in philadelphia, we are at 46 degrees and still cloudy but by 5:00, 6:00, 7:00 a.m. you see the snow breaking out in philadelphia as it's temperatures going into the 30s and stay in the upper 30s as we go into the afternoon hours tomorrow. future tracker 6 at 5:00 in the morning. there is that band of snow, it's fairly intense for a short period of time. during the rush at 8:00 a.m. a mix along the coast at 8:00 and still snowing heavily along the shore communities and it will be melting with the higher sun angle and starts to break apart to the north and west and by lunch time you see snow returning to the northern and west and flakes are falling along the shore and by the afternoon snow squalls are developing mixing with sunshine and strong winds and even more energy passed through in the afternoon. so the steadiest of the snow tomorrow morning, between 7:00 and 9:00 the biggest

the wind is bringing in cold air. the cold air isn't here just yet. the winds have died down just a little bit. we were seeing gusts at 40 miles an hour in philadelphia. now at 32 miles an hour. and dover topping 40 miles an hour also, atlantic city. look at toms river, close to 50-mile-per-hour wind gusts right now. the strongest wind gusts will be this morning. but these winds will still be blowing this afternoon. that's with colder air that's coming into the area. and that's just starting to move in. so, the temperatures have been moving down. in fact, we've just dropped three degrees in the last hour. 45 in the suburbs. 49 now in new jersey. that was in the 50s last hour. 47 degrees in the lehigh valley. and it's dropped to 49 degrees in delaware. so, we're seeing the temperatures come down and they'll cool down a bit more before they start warming back up. new jersey 48 degrees this afternoon. a sunny and windy day, the winds will be blowing at the shore. high of 49 degrees this afternoon. the entire area will see temperatures stay in the 40s. wi

, so go make clean air. that's not how you should do business. because congress should be directing agencies in the executive branch and every area, whether it's finance, health care, and the environment, to say here's the framework that you have. the co2 issue actually is a great example of that. when you look at the carbon issue, we have a supreme court case in 2007, mass v.epa, where six states sued the federal government to say regulate co2 to mobile sources. the u.s. supreme court didn't say that the epa should regulate, by the way. it said go make a decision. you have to determine whether co2 is something that should be regulated or not. and you just can't simply fail to make a decision. that was the supreme court decision in 2007. 2009, endangerment finding by the epa. all right? and then you had two responses since. you've had the tailoring rule that was struck down by the u.s. supreme court in the u.r. decision and then you have the clean power plan that has been stayed bit u.s. supreme court. so tw

bringing in warm air.m the north so watch what happens the rest of afternoon. cold air sweeps down and we do change over to snow but notice how it's not as heavy. that's because there's drier air up here. there will be some moisture to make some snow but anything you see after about noon is going to be lighter and then maybe it pops through and gives us just a little additional accumulation but that's going to be it. so, that afternoon portion of the storm if snow does come back probably only gives you a you believe cold front extra couple of extra inches and that's it. with the winds building we still have the possibility of a lot of drifting snow and very poor and and visibility. blizzard warning still in effect in the northern suburbs until 6 o'clock because of that drifting snow. heavy rain will be the story southeast and then along i-95 we are seeing some mixing and again the heaviest of all of this is between now and noon. what are we expecting on the ground? we have shifted all of these lines farthe
