scientists are warning that one in six deaths worldwide are caused by pollution — that's three times more than those caused by aids, tuberculosis and malaria combined. in a report published in the medicaljournal the lancet, researchers say prolonged exposure to high levels of air pollution can lead to heart disease, stroke and lung cancer. they're calling on governments, particularly in the developing world to take action. as andrew plant reports, the vast majority of deaths are in countries like india and china, that are going through rapid industrialisation. particles in the air, built up and breathed in. and pollution in the water they can end up inside our bodies. exposure to man—made chemicals a factor in 9 million deaths in 2015, says a study, akin to bidding to killer conditions like heart disease, strokes, and lung cancer. in this global study, pollution was linked to one in every six deaths worldwide. pollution from factories was the biggest killer, linked to more than 6 millionjust around the world in a single year. in some african countries, 25% of deaths were attributed to pollution. like chad, somalia, and niger. in india, the figure is also about a quarter. and in china, twitter %, one in five, were linked to pollution. this time lapsed video showers pollution growing. the study in the lancet and bowled a0 researchers worldwide. derozan pulls, such as bank on, which is unwell. china is flattening out. —— there are examples. there are a lot more things to do in other areas, but we do know how to solve the problems. they have been done time and time again. it is about bringing no solutions to bear. chemicals in the air with the biggest killer, contaminated water the second. the research is a air pollution is reaching a crisis point, worldwide, and said that those with existing heart and lung conditions, elderly people, and children are being hit the hardest. joining us is dr michael kleinman, a professor of environmental toxicology at the university of california. thank you forjoining us on bbc news, dr michael kleinman. how surprising you by the findings?” have been aware that the levels are killing people. —— how surprised argue at the findings. the one in six figure is astounding. but when looking at what we know about how air pollution works, it is not, it you know, it seems like an u nfortu nate you know, it seems like an unfortunate finding that air pollution is definitely contribute in two illness and two deaths. throughout the world. of course, we are talking about humid gusts, but there is an economic gust for those countries that are developing. how can this country ‘s balance of rapid industrialisation with caring for the environment? —— economic cost. there are art to things to give in mind. firstly, there are costs with clear the air. mind. firstly, there are costs with clearthe air. in mind. firstly, there are costs with clear the air. in developing countries —— in developed countries, a lot of effort has gone into developing technology. that is now available. so the development costs are reduced when you are trying to apply this to a developing nation. the other thing that i think is really important to keep in mind is that before people die, they get sick will stop when they are sick, they are not able to work properly 01’ they are not able to work properly or to be efficient. they can't take ca re of or to be efficient. they can't take care of their homes. they can't take ca re of care of their homes. they can't take care of their homes. they can't take care of their children. and that is a tremendous cost to society. so even though an investment has to go into reducing air pollution, there isa into reducing air pollution, there is a payback, at least in the us, where we looked at the numbers in terms of the cost versus the benefits. the benefits far outweigh what the costs were in terms of reduced medical costs, reduced problems with childcare. i think there is, you know, very good evidence to say that cleaning up air pollution is good for people and for the economy. just briefly, it is interesting that some progress has been made with traditional forms of pollution, things like cooking, while pollution associated with things that fossil fuels is increasing. this is true partially because populations are increasing. therefore, there is more need for various fuels for energy, for transportation, for producing goods. but our ability to use less polluting fuels is getting better. we've moved towards using more solo, more wind power, and in the future, we will produce things that will reduce a lot of the emissions. —— solar. 0k, dr michael kleinman, they do so much. dr michael kleinman there from the university of california. —— thank you so much. let's take a look at some of the other stories making the news. the controversy over how president trump dealt with the family of a soldier killed in action has taken another turn. former marine and white house chief of staff generaljohn kelly says he was "stunned" by the criticism made by a congresswoman who was with the family when they received a call from the president. sergeant ladavid johnson was one of four servicemen killed in niger by islamist militants earlier this month. the european council president donald tusk has said there's no space for the eu to get involved in mediation over catalonia. he was speaking on the first day of an eu summit, and said the crisis over the region's bid for independence would not be widely discussed by european leaders. the men's magazine playboy is to feature it's first ever transgender centrefold. ines rau is a french model who first appeared in the magazine three years ago but will now be the centerfold for the first time. she will appear in the november issue, which pays tribute to the magazine founder hugh hefner, who died last month. the charity unicef is warning that 12,000 rohingya children are at grave risk after fleeing myanmar for bangladesh. more than half a million rohingyas have arrived in bangladesh since august alone and now face food shortages and the threat of disease. clive myrie reports from the kutupalong refugee camp in bangladesh. you may find some of the images distressing. every breath is a struggle for mohammad ibrahim. six months old and fighting pneumonia, he is terribly weak and malnourished. he has just a 50—50 chance of seeing out another day. a sense of sorrow hangs heavy in the air at this clinic in bangladesh. 80% of the patients are rohingya muslim refugees, and many are malnourished children, the weakest of the weak. the mother of an 18—month—old summed up the nightmare of so many rohingya women. translation: we had to run from our village, but we had so little to eat. then, when we managed to get food, i couldn't feed my child. she's so sick, but if god wishes it, she'll survive. working with the local staff here is ian cross, a former gp from leicester. tears come to my eyes sometimes. it's dreadful. you just do what you can, you know? in a way i'm lucky that i'm a doctor. i've got my hands and my tools, i can help to make people better. if i wasn't able to do that i'd feel more frustrated and i'd feel even worse. but when you are hard at work, you can cope with it. it is a depressing truth in this crisis that close to 60% of the more than half a million rohingya muslims who've escaped myanmar are children and teenagers. and they've seen some terrible things, like this girl. she's called this refugee camp in bangladesh home for almost two weeks. her story of the night she had to flee myanmar is depressingly familiar. villages torched, and her mother dying in the flames. "they're killing all the muslims," she told me. "slaughtering innocent rohingyas. "we have always been treated as lesser people in our own land. "now, they want to finish us off." but dangers lurk in exile, too. young women are vulnerable. and the chance of children falling into the hands of sexual predators or exploited for their labour is ever present. the families here have nothing. they are trying to survive on a daily basis. and some of them at some point might be tempted to give away one of their children for domestic work. you know, not going to school, sometimes sexual abuse. so, the risks are high. but there is light amidst all the gloom. children in the camps are getting vaccinated against cholera and other diseases. there's even a chance to watch cartoons. and youngsters are never allowed to feel ashamed of who they are. in this class, they're reciting nursery rhymes from their homeland. 0utside one refugee camp, we found, by the side of the road, this girl, who's nine, cradling her younger brother. too young to understand the bundle in her arms was severely malnourished, we alerted unicef, and doctors are now treating them both. but some will never have the chance to return to myanmar. the day after we filmed mohammad, we were told he died. he was buried in a tiny grave before sundown. clive myrie, bangladesh, bbc news. two former us presidents have made veiled criticisms of the trump presidency. fellow republican george w bush has condemned what he calls the ‘bullying and prejudice' in today's american public life. though mr bush didn't mention his successor by name, he said that civic values were forgotten. and speaking at a rally in newjersey to support a democratic party candidate for governor, president trump's predecessor barack 0bama took aim at what he described as the fear and bitterness that marked the 2016 presidential election campaign. and so the question, now, at a time when politics just seems so divided and so angry and so nasty, is whether — whether we can regain that spirit, whether we can support and embrace comedy who wants to bring people together. gary 0'donoghue is in richmond, virginia, for us. so coded criticism coming from across the political divide? yes. and not so coded in the case of president bush, really, which is ironic, given that he is meant to be on the same side as donald trump. he was very explicit, even though he did not name him in the kinds of language he used, really criticising notjust his style, but on immigration issues, on issues of trade and on the nature of politics. president 0bama was more circumspect. it does not want to get into a slanging match with donald trump. if he went head—on, that is exactly what would have happened. so he couched his criticism. that might be too subtle for a lot of people. politics tends to be straightforward, so as to cut through. this is a race that is really the only competitive statewide race in the country in this year. there will be acres of ink spilt, analysing this race, in terms of what it means for the country, come november. that is why they are putting effort in here. that is why barack 0bama was here. he knows the direction, the momentum going into next year and into the mid—term elections will be important, and that will be infused with what happens here in virginia. i suppose what happens them is quite a test of the democrats, isn't it, gary? it is. hillary clinton, this was the only state she won in the democrat election. the democrats have had the governorship for the last two terms. they ought to be ahead here, and they are by bit. so any gains by republicans, particularly in the governor's race, will be seen as a blow. but any sense that they can open up the gap, if you like, with republicans, will be seen, i think, nationally, if you like, with republicans, will be seen, ithink, nationally, as if you like, with republicans, will be seen, i think, nationally, as a bit of a fillip to their cause. the problem is that democrats, and we saw this night, the most popular democrat in the country is barack 0bama. he can run again. and they are struggling to find that new generation of democrat leaders that are going to come again and inspire in the way that barack 0bama did. —— he can't run again. they have not produced yet. hillary clinton was not the answer, obviously, and they are still struggling to find those names to take on the mantle, the next generation to take on the mantle. gary o'donoghue in virginia, thank you. stay with us here on bbc news. still to come: new zealand has a new prime minister — the youngest in 150 years. we'll be finding out what challenges jacinda ardern faces and what her policies are. a historic moment that many of his victims have waited for for decades. the former dictator in the dock, older, slimmer and, as he sat down, obedient enough. dawn, and as the sun breaks through the piercing chill of night on the plain outside korem, it lights up a biblicalfamine, now, in the 20th century. the depressing conclusion — in argentina today, it is actually cheaper to paper your walls with money. we've had controversies in the past with great britain but as good friends, we have always found a good and lasting solution. concorde bows out in style after almost three decades in service. an aircraft that has enthralled its many admirers for so long taxis home one last time. this is bbc news. the latest headlines: experts say the world's pollution crisis is linked to more than one in six deaths across the globe. the un says as many as 12,000 children are crossing into bangladesh every week, as they flee the violence in myanmar. many desperately need medical help. new zealand's labour party will form the country's next government as part of a coalition. party leaderjacinda adern will become new zealand's next prime minister, the third woman to hold the post. the decision to put labour in power was made by winston peters, leader of the new zealand first party, who was left as kingmaker after an inconclusive election result in september. the new coalition ends the rule of the national party, which has been in power since 2008. helen clark is a former new zealand prime minister, who herself worked with mr peters. she had some advice for ms ardern. let's speak now to colinjames, a political journalist and commentator in new zealand. earlier we were speaking to your former prime minister, helen clark, and she was optimistic about how this coalition was going to work. what do you think? i thinkjacinda ardern, despite her youth, what do you think? i thinkjacinda ardern, despite heryouth, because people look at her and say that she is young and pretty and all the rest of it, but does she have substance? i have tracked this sometime, and she does have substance. she has substance in her intelligence, and in the way she deals with people. insiders say the reason winston peters chose the labour party in the end was because of the way she handled the negotiations. i think there is a fair chance she will in fa ct there is a fair chance she will in fact manage this 3—way coalition with the other partners as well, the greens, effectively through the three years. you have mentioned there are three. this is a crowded relationship. in the past, the greens and new zealand first have not always got on well, have they? no, they haven't. but i think jacinda will be capable of working with them. also, james shaw, the relatively new co— leader of the greens, is a much less rigid character than some of their co— leaders in the past. i think they will be able to work reasonably well together. and they do have a point of agreement, that they do want a climate change commission and they wa nt to climate change commission and they want to aim for net zero carbon emissions, which is quite a significant shift from the current government. that is not something i would have expected the new zealand first party, which is a socialist and nationalist party, if i had gone back five years. colin, thank you. police in los angeles have opened an investigation against harvey weinstein regarding sexual assault allegations that date back to 2013. earlier this month police in new york and london also began investigating similar claims against the movie producer. the 0scar—winning actor tom hanks says there's now no way weinstein will ever be able to work in hollywood again. he's been speaking to our arts editor, will gompertz in new york, to mark the publication of his new book of short stories. one thing about the hermes 2000. it was a lot heavier than the toy typewriter. the green carrying case banged against her legs as she carried it home. she stopped twice, putting the machine down, not because she needed to rest, but because her palm had gotten sweaty. were you worried about coming out as a novelist? well, petrified, of course. i still can't believe that people have put my stories in a book and are going to try to make people pay in order to read them. it's astounding. all these, broadly speaking, are set in america. what was the picture you were trying to paint? america is a place of relentless ongoing chances. you don'tjust get second chances in the united states, you get third, fourth, fifth, sixth and seventh chances. you get to remake yourself in the united states. is there any chance for harvey weinstein to come back? no. no, i think we're in a watershed moment. this is... this is a sea change. i think his last name will become a noun and verb. he'll become an identifying moniker for a state of being for which there is a before and an after. i don't... perhaps all men, myself included, should pipe down and not try to explain it and not try to comment on it. certainly not to try to defend it. tom hanks, speaking to will gompertz. in the early 1960s, jane goodall‘s studies of wild chimpanzees revolutionised scientists' understanding of primates, particularly how much they have in common with humans. now a new documentary draws on more than 100 hours of never—before—seen footage shot in the gombe stream national park in tanzania, where goodall did some of her most important work. peter bowes reports from los angeles. there have been other films about jane goodall‘s life, but none quite like this. the footage is impeccably preserved, and enhanced by modern day technology, it tells a story of a woman who had no scientific training when she first started studying chimpanzees in tanzania. every time i see it it is more emotional. i don't know. i see new things. seeing your life evolves, and also taking me back to that best time of my life. the film was shot in 1962 by hugo bamburgh, the dutch photographer sent to africa by national geographic to record the work of the young naturalist he would later marry. the archive that jane and hugo assembled in gombe in the 1960s is one of the most important repositories of 60 millimetre film from the 20th century. awa capturing something which had never happened before in the history of civilisation and will never happen again. it had long been thought we were the only creatures on earth that used and made tools. and here was david greybeard, using a tool. it was so amazing. i had to wait to see it again before i could completely believe what i'd just seen. completely believe what i'd just seen. because i knew it was going to make a difference. an audience of 15,000 attended the documentary‘s us premiere at the hollywood bowl and theatre in los angeles. —— amphitheatre. with a live orchestra performing to score by the renowned composer philip glass, it was a surreal screening, an emotional rollercoaster. forjane surreal screening, an emotional rollercoaster. for jane goodall, surreal screening, an emotional rollercoaster. forjane goodall, it was an opportunity to share her passion for conservation.” was an opportunity to share her passion for conservation. i have a very important message to take around the world, which is that we are destroying this planet and that we need to get together to try and make change. hollywood has fallen in love with jane, saying the film could win an oscar. that jane goodall‘s heart is still in africa. and that is the way it is looking. you can keep up—to—date on the bbc news website. and you can get in touch with me and most of the team on twitter. i'm @duncangolestani. hello there. it was pretty grey for many on thursday. wet weather as well. heavy showers and rain lasting through the evening and through the night. not great for driving. there is a squeeze in the isobars around low pressure bringing heavy rain through thursday and overnight. some gales with this. this is storm brian, which was named during the day on thursday. that looks like the next set of autumnal gales. but for friday, it starts grey and gloomy. fog in northern ireland and york and further north. low cloud and hill fog with remnants of low pressure further south. but it is an improving as the day wears on. increasing amounts of dry and bright weather and even sunshine until late on. that is until this next area of low pressure comes in bringing rain to northern ireland, wales, and the south—west. and the strengthening wind. despite the fresh air, it will be pleasant due to the brightness in the afternoon. but a grey start. through the evening, rain rattling east on strengthening winds. the game might be dry, west ham, brighton. the rain's not too far away though. it will rattle through quickly through the night due to storm brian. gales, severe gales, quite widely in southern and western areas. for some south—eastern areas, the first gales of the season. a0—50mph inland. 60, perhaps, locally, 70 around the coast. with the wet ground, that could bring down trees and disruption. very large waves indeed. that is because this storm coincides with spring tides as well. so, some dangerously large waves around the coast to be avoided. so, it does look like it will be a bit of a feature as it goes across the uk. southern areas especially. strong and gusty winds further west, eventually getting into northern ireland and south—west scotland. as well as that, wet weather. ahead of that, despite the wind, dry and bright weather on saturday and in eastern areas. temperatures getting to about 16 degrees. it will be the wettest weather in the way, especially with these showers. saturday night, low pressure pulling away. a westerly wind driving them east. another showery day going into sunday. again, eastern areas are best for brighter weather. clearly, there are warnings out. and do stay up—to—date with those warnings. they're on the website. scientists are warning that one in six deaths worldwide are caused by pollution. in a report published in the medicaljournal the lancet, researchers say prolonged exposure to high levels of air pollution can lead to heart disease and lung cancer. they're calling on governments in the developing world to take action. the charity unicef is warning that 12,000 rohingya children are fleeing the violence in myanmar for bangladesh every week. more than half a million rohingyas have arrived in bangladesh since august alone and now face food shortages and the threat of disease. theresa may has been in brussels at an eu summit to assess the progress so far towards brexit — and crucially, whether talks can start on a trade deal. the german chancellor angela merkel says there are "encouraging" signs of progress but eu leaders have suggested that insufficient progress has been made to move on to trade talks. now on bbc news it's time for a look at the day in parliament.
