a warning from sir david attenborough to world leaders — climate change is the greatest threat to humanity in thousands of years. as one of the world's foremost naturalists, he is invited to talk to the un about what lies ahead if we don't take action, the collapse of our civilisations, and the extinction of much of the natural world, is on the horizon. but with carbon dioxide emissions rising once more, is there the political will globally to tackle it? also tonight... the government's top lawyer tells mps the prime minister's brexit deal contains a calculated risk but it's a sensible compromise. i was embarrassed at first, quite embarrassed, but now, i don't know, it's come as a way of life for me. how one in eight working people are now living in poverty, the highest number in 20 years. her husband was murdered by somali pirates, she was kidnapped. but whyjude tebbutt is now helping the only man convicted. cheering and applause.

and a rapturous reception as michelle obama visits the london schoolgirls she met when she was first lady. and coming up on bbc news. another saints manager gets his marching orders, as southampton sacks mark hughes afterjust eight months in charge. good evening and welcome to the bbc news at six. climate change is humanity's greatest threat in thousands of years. that's the stark warning from sir david attenborough , who was speaking today at the opening ceremony of united nations climate talks in poland. the broadcaster — who's 92 — said climate change could lead

to the collapse of civilisations and the extinction of "much of the natural world". our science editor david shukman has the story. it's been a year of deadly fires and record heat. and also new warnings from scientists about the dangers of living in a world of rising temperatures. with a risk of many more scenes like this, a social media campaign has gathered voices from around the world, calling on governments to take action. please welcome, sir david attenborough. the campaign spokesman was given a rare chance to appeal directly to this global forum. right now, we are facing a man—made disaster of global scale. our greatest threat in thousands of years — climate change. if we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon. there was applause, but not much.

maybe because tackling climate change is so difficult. poland, like many countries, depends on coal. we went down a mine to see the grim process of getting it out. thousands here think a green future threatens theirjobs. what would you say to a polish coal miner about his future, given what's been discussed here in this conference? all you can say is that things change. and there's a process of history which is now moving to its end, and you will have to find, your children will have to find new ways of living. so as the conference continues, there will be tense arguments over what to do. with so many countries represented here, and thousands of delegates, together with incredibly complicated negotiations, it's easy to forget

what this is all about. so let me show you what's happened to global temperatures. there's one stripe here for each year since 1850. blue is for below average, orange is for above average, and the most recent years are the hottest, so they are marked in red, and the big concern is where the world is heading next. stronger storms and the sea—level rising are growing threats. small island states feel the most vulnerable. what kind of effort must be put into rebuilding? when your entire economy is wiped away, imagine what if the entire economy of ireland or england was washed away? where would you start? and that is the reality of climate change. outside the conference, coalfires are burning, each one polluting the air. scientists say stopping this is essential, and it will be a huge challenge.

the big question is what happens next on the one hand you have donald trump who basically says all this global warming stuff is none sense dismissing what his own scientists are telling him. on the other there is big change in renewable energy, the price of wind and solar power falling, which makes a green transition more plausible, if i had to give a guess i would say it is going to that, eventually but maybe not as rapidly as many here would like. the government's most senior lawyer has urged mps to back the prime minister's brexit agreement. geoffrey cox concedes the controversial northern ireland backstop is a calculated risk though he says it's a sensible compromise. meanwhile theresa may insists she will still be in a job in two weeks‘ time, brushing off speculation about her future if mps reject her brexit agreement when they vote on it next week. vicki young has the latest.

parliament's gearing up for one of its most important votes ever. and two—and—a—half years after the eu referendum, the debate is still raging. the prime minister's been touring the uk with her brexit message. it is a tough time. and today she was on the day time out tv sofa, pleading with mps to back her deal we have duty to do what people asked us to do, to leave the european union, but this is a deal that does it, in a way, that does look after people, does look after people's security, and jobs for the future, i think what i would say to mps, we need to hold our nerve. will you be booking a holiday? do you think you will have a job if two weeks' time i will still have a job if two weeks' time. she has lot of work to do convincing, the backstop isa work to do convincing, the backstop is a safety net to ensure there are no border checks between northern

ireland and the republic, if a trade deal isn't in place. the uk would be ina deal isn't in place. the uk would be in a temporary single customs territory with the eu. northern ireland would also have to follow some eu rules on things like food product, and goods standards. mps want to know how the uk can get out of this? the government has refused to publish the legal advice has received but today he came to the commons to answer questions. i would have preferred to have seen a clause that allowed us to exit if negotiations had broken down. but i am prepared to lend my support to this agreement, because i do not believe that we are likely to be entrapped in it permanently. the question for the house is to weigh it up, against the other potential alternatives, and to assess whether it amounts to a calculated risk. the the government should do the right

thing and make this full advice available. with so much at stake, for all our constituent, with eight days to go before the vote on the deal, this house and this country deserves bet refer this government. —— betterfrom. deserves bet refer this government. —— better from. theresa deserves bet refer this government. —— betterfrom. theresa may's under fire from all sides, some want another referendum. the idea of going ahead particularly with this deal is divisive. people deserve a say on what terms we should leave. today they deliver add petition to downing street, signed by more than one million people. just down the road, others complain that theresa may's deal is a betrayal. it doesn't deliver on any of the opportunities that leaving the european union will provide and it leaves news a swam lid situation. it is neither in nor out. it is mainly in wand we don't like it s with just ore a week to go tensions are running high. arguments between those who think the deal doesn't

deliver brexit in a meaningful way and those who want to stop it happening at all costs. the protestors here a re happening at all costs. the protestors here are unlikely to change their minds. theresa may's only hope is that dozens of her own mps a man has beenjailed for at least 16 years for murdering a midwife, samantha eastwood after a lengthy affair. michael stirling admitted killing the 28—year—old from stoke—on—trent. her body was found in a shallow grave near caverswall in staffordshire. at the sentencing, it emerged that stirling had gone for dinner at his parents‘ house, with samantha eastwood's body in the back of his van. a man whose allegations sparked the investigation into an alleged westminster paedophile ring — which then ended without any convictions — can now be identified after a judge lifted an order barring publication of his name. carl beech, who is 50, was previously known by the pseudonym nick. he's been charged with fraud and perverting the course of justice. our home affairs correspondent june kelly is outside newcastle crown court — what more can you tell us? so the name has been revealed, what

more can you tell us? well, fiona the claims by carl beech led to a £2.5 million investigation by scotla nd £2.5 million investigation by scotland yard known as operation midland. he made sexual abuse allegations against the former chief of the defence staff lord bramall and the politicians sir edward heath, lord brittan and harvey proctor, as a result, no action followed. the police then began investigating carl beech himself and that was led by the north bra force, asa that was led by the north bra force, as a result, carl beech was charged with 12 counts of perverting the course of justice, making with 12 counts of perverting the course ofjustice, making false allegation and one count of fraud. he is in custody, around he appeared today, by videolink and he is due to stand trial here at newcastle crown court, next may. the number of working people in poverty is the highest in 20 years, that's according to a new report by thejoseph

rowntree foundation, which focuses on tackling poverty in the uk. relative poverty‘s defined as an income less than 60% of the average of people living in similar circumstances. four million workers in the uk now fall into this group — that's one in eight. and that figure's risen by more than 500,000 in the past five years. our correspondent danny savage has been spending time with one of those affected. i open the curtains in the morning and hope for the best. sue prince constantly worries about money. every day, i check my bank. i need to know what's coming and going out of my account. she has three part—timejobs, but it still leaves her with precious little to live on after paying her overheads. my rent is £495 a month, plus there's other household bills as well. i'm still only left with about £80 a month. that goes to buy my food and top up my gas and electrical. buxton‘s a bit out in the sticks, it and does get cold.

on a tuesday, the day ends with a visit to an informal food bank... how important is getting this food to you each week? very. it is to me, anyway. ..where sue collects a few days' worth of supplies. i was embarrassed at first, quite embarrassed. but now... i don't know, it's become a way of life for me. and i know i need it. i wouldn't do it if i didn't need it. for £1.50 a visit... food which is donated, damaged or nearly out of date is handed out. they can't afford to buy it, so need this. they then return to their homes on this estate in rural derbyshire, just a handful of the 4 million people in the uk who it's claimed are in work, but living below the poverty line. keeping the rent going, keeping a roof over your head, is often a really high priority. we also then find that they're trying to pay the water bill, the electricity, the heating and council tax, so a lot

of people will be rotating between those different bills and each week working out, "which one don't i pay?" the government, though, says far fewer people are living in poverty and household incomes have never been higher. sue is getting a little more money now that she's moved on to universal credit, but is still reliant on food hand—outs and doesn't see that changing. danny savage, bbc news, buxton. our top story this evening. sir david attenborough warns, in a speech to world leaders, climate change is the greatest threat to humanity in thousands of years. and still to come... of this evening's third round draw.

a british woman whose husband was murdered by somali pirates, who then kidnapped her believes the only man convicted in connection with both crimes is innocent. jude tebbutt and her husband david were attacked while on holiday in kenya seven years ago. she was held hostage for six months. mrs tebbutt says the metropolitan police team who flew to kenya to help the local investigation helped to convict an innocent man — and she's supporting his appeal. our special correspondent lucy manning has been speaking to her. dude tebbutt is a long way from the kidnappers. from somalia where seven yea rs kidnappers. from somalia where seven years ago, she was freed after being held for six months. she had been ca ptu red held for six months. she had been captured after her husband david was murdered on their holiday in kenya.

ididn't murdered on their holiday in kenya. i didn't know he had died. ijust assumed he was alive, but then my son told me he... he had died. now, she has her loss and herfreedom, and she can't put those terrible events behind her. yeah, i do want justice. but i don't wantjustice at any justice. but i don't wantjustice at a ny cost. justice. but i don't wantjustice at any cost. a kenyan, ali babitu kololo, was the only man convicted. butjude tebbutt doubt he is a guilty man and is supporting the appeal he is now bringing in the kenyan courts. i thought there would be someone coming through that door that was a representation of the two men then drag me out of bed that night. but honestly, lucy, it wasn't one of those men. it wasn't one of those men. i think a wrong should be righted. and when i say wrong, i

mean the fact that mr kololo didn't have a fair trial. officers from the metropolitan police flew to kenya to help the investigation. but the bbc now understands that the senior officer, neil hibberd, is himself being investigated about his role and will be interviewed by the national crime agency. a letter from the met police as they are looking at whether mr hibbert, who has now retired, may have committed a criminal offence or whether there has been misconduct or gross misconduct. mr hibbard's lawyer told the bbc he intends to cooperate with the bbc he intends to cooperate with the police watchdog investigation. mr neil hibbard said to me that if it was the last thing that he did, he would find the murderer of david and the people responsible for abducting me. and i believed him, i really believed him. i think they have to take ownership of what they did back in 2011, the team that

helped convict mr kololo. an innocent man. mr kololo's lawyers claim mr hibbard didn't disclose that there was forensic testing of evidence which undermined the prosecution because my case, and he misled the court by giving selective evidence. his lawyers also claim that mr kololo was, for most of the trial, without a lawyer or interpreter, and was tortured by kenyan police. some people might find it surprising that you're fighting for the man who has been convicted of involvement with the death of your husband. if there has been a miscarriage ofjustice, it needs to be investigated. if i had been murdered, david... he would be sat here now because... he was a really good man. and he was an honourable man. and the honourable thing now to do is to hopefully get

afair thing now to do is to hopefully get a fair trialfor thing now to do is to hopefully get afairtrialfoer thing now to do is to hopefully get a fair trial for mr kololo. that is the least that he deserves, really. jude tebbutt feels the metropolitan police wanted to go to kenya and get their man, but she doesn't think he is the man at all. lucy manning, bbc news. a 23—year—old man has been shot in south west london as armed police stopped the robbery of a cash van. officers from the metropolitan police flying squad were lying in wait to stop the cash—in—transit raid outside a supermarket in wimbledon. the man was shot after officers confronted suspected robbers outside the store. it seems hardly a week goes by without news of further problems hitting britain's retail industry — in particular the high street. figures compiled by the bbc suggest 20,000 people have lost theirjobs in the sector this year — and a similar number are under the threat of redundancy. our correspondent colletta smith has been hearing from those who've been directly affected by the turmoil in the high street. what else have we got? do you want the creamed potatoes?

dinner‘s well on the way, but gemma's not been dishing up here for long. she was made redundant from the electronics store maplin in march, a bolt out of the blue for her and her colleagues. you've got kids at home and you've got a house to run, you know? it's really, really scary. so we then got all our things, got the little boxes with our belongings in and we all went home. within 45 minutes, we were all out of the building. once we got the e—mail and we left maplin, it was like a race to get a job. and you're against people who you know are good at what they do. did you feel desperate? idid. yeah, definitely. because i bought my house the september before. i was planning on moving into it in april. that was only one month before it happened. i was like, "i'm going

to lose the house. i've literallyjust bought it. i'm turning 25 in a month's time. i'm not where i should be". you go to bed dreaming about it, nightmares, bills. it's just awful. horrible, horrible situation to be in. unemployment is at a record low, but with recruiters saying fewer jobs are available in retail than any other sector, workers are having to look elsewhere. if you want to keep that interaction with people, going into another service sector role within hospitality, the crossover‘s absolutely huge. with so many retailjobs under threat at the moment, unions are worried that workers aren't being properly valued. retail is a realjob. it's a properjob. there's nearly 3 million retail employees in the uk. it's a huge piece of the economy. so it should be looked at in a more serious way than it is at the moment. do you feel safer now that you're kind of beyond that retail environment and you've gone into different areas? you can put your heart

and soul into a job more when you know that you'll be there in 15, 20 years' time. the plan is not to move again. ever? yeah, ever. i'm happy. i've found a job which is... yeah, really ticks every box. love it. definitely life after maplin. life after retail. absolutely. colletta smith, bbc news, in rotherham. football, and it's been confirmed that the 2021 women's european championship will be held in england. it'll be played at eight venues across the country, culminating in a final at wembley. and the england men's team have been drawn to play the netherlands in the semi—finals of the new uefa nations‘ league tournament in portugal nextjune. the former us first lady michelle obama says she is "touched and inspired" as she returns to meet girls at a london school she first visited in 2009. speaking this afternoon, mrs obama encouraged female students to "lift each other up" rather than tear each other down as part of a tour for her new book. our community affairs correspondent

adina campbell has been talking to some of the girls she met. michelle obama made her first visit to the school back in 2009. this afternoon michelle obama was welcomed back with overwhelming applause from schoolgirls in north london, a place which held special memories for the former first lady. it gives me a level of focus and determination in the work that i do when i get to see you all up close and asi when i get to see you all up close and as i said then, you remind me of me, and all the fears and all the challenges that you face. and you quys challenges that you face. and you guys give me a sense of comfort. michelle obama made her first visit to the school back in 2009. and nine years later, her appearance and words of advice have had a long—lasting impact on former students and staff. she's inspired me to go to law school and she's inspired me

professionally in so many ways to take on so many different voluntary roles. it gives us power, kind of. like, i'm a woman from a working—class background who is black, obviously. but it just feels that i'm there as well and it feels like my voice is being heard through her and it'sjust wonderful. and teachers here say their close relationship with the former first lady is deeply meaningful. she's written to us, she's congratulated the girls. she's taken them to oxford university and she's invited them to washington. today, a new generation of schoolgirls got to meet their role model. mrs obama was on stage for an hour, and spoke openly about a wide range of issues, including her time in the white house. being first lady wasn't the easiestjob in the world. but i got strength from your hope and what i could do for you. it's notjust these girls who are inspired by michelle obama's personal story.

herjourney from a working—class neighbourhood in chicago all the way to the white house has captivated millions of people all over the world. it was really good and inspiring. it was just so amazing to see michelle obama up so close. how did you find today's assembly? it was really inspiring to look up to her as a role model and to remember the past memories she created with us in our school. and her presence here continues to have the same effect. well, this book tour has been one of the most eagerly anticipated events in recent weeks, with so many people looking forward to seeing michelle obama here at the southbank centre in london. tickets for tonight'sevent sold out within minutes, and about 10% of those tickets were allocated to schoolchildren and charities here in london. in the next hour or so, the former first lady will be in

conversation with the nigerian author tim amanda negotiated ichi, talking about her new memoir in front of thousands of people. despite the weather, many people will be looking forward to seeing and hearing from one of the most talked about women in the world right now. thank you. i don't know what you were doing when you were in primary school, but i wonder how it compares with this — an eight—year—old boy has been revealed as youtube's highest—earning star, reviewing toys and earning just over 17 million last year. welcome to my toy review! ryan of ryan toysreview posts most days and his earnings have doubled from the previous year. asked why kids liked watching his videos, ryan said: "because i'm entertaining and i'm funny." time for a look at the weather. here's chris fawkes. now challenge for him! entertaining and funny, please. i do have something to blow off your socks, a

rainbow. notjust one, but an incredibly rare triple rainbow. one here, here and here. there is talk on the internets and suggest that these things haven't been photographed before 2011. but what i do know is that they are incredibly rare. i have never do know is that they are incredibly rare. i have never seen one do know is that they are incredibly rare. i have never seen one before and we have gordon to thank from gloucestershire for sending us that picture. over the next few days, it is often going to be pretty cloudy. we see rain returning mid week, and it is going to become windy towards the end of the week, possibly disruptive. we are talking about the weather overnight tonight, and the skies are clearing, with temperatures falling quickly, but we have showers around. those showers will continue to affect northern and western scotland, with a few running into northern ireland. so with temperatures going below freezing, it is going to be a cold night. you can imagine that there will be the risk of icy patches to start off tuesday. although it will be a chilly start to the day, most of us

will have a fine start with plenty of morning sunshine. and through the day, we will see the clouds thicken across much of england and wales. that to a degree will trap some of the chilly air near the surface. it will be the coldest day of the week for many of us. and we have more rain to come midweek. a band of wet weather will push into northern ireland, england and wales, accompanied by a strengthening south—westerly wind. the winds are mild, said temperatures will be rising. as the rain bumped into the colder air, we may see snow across the southern hills in scotland. in the southern hills in scotland. in the north of scotland, it should stay dry and bright. towards the end of the week, we will will be watching the developments of this area of low pressure. this could bring a spell of very windy weather, may be severe gales across northern areas. there is the potential on friday for some disruption to

transport and perhaps some power supply issues as well. we are keeping a close eye on that. for the time being, its going to be quite chilly, then turning mother but wetter towards the middle of the week. a reminder of our top story... a warning from the naturalist and broadcaster sir david attenborough to world leaders — prime a change is the greatest threat to humanity in thousands of years. that's all from the bbc news at six, so it's goodbye from me, and on bbc one we nowjoin the bbc‘s news teams where you are. hello. our top stories: time is against us. that is the warning from sir david attenborough. on climate change as critical international talks begin. if we don't take action, the collapse of our civilisation is and the extinction of much of the natural world is on the horizon. the government's top

lawyer tells mps the prime minister's brexit deal contains a calculated risk over the northern ireland backstop, and it is a sensible compromise. the man who admitted killing 28—year—old midwife samantha admitted killing 28—year—old midwife sa ma ntha eastward admitted killing 28—year—old midwife samantha eastward is sentenced to a minimum of 17 years injail. her husband was murdered by somali pirates, but she was kidnapped. jenna tebbutt is talking about how is she now helping the only man convicted. in a moment, it will be time for sports day, but first let's ta ke time for sports day, but first let's take a look at what else is coming up take a look at what else is coming up tonight on bbc news. critical un climate talks opened in poland today and at 8pm we will be speaking to an activist from the radical
