the world's top climate scientist issue their starkest warning yet. act now to stop, change causing catastrophic damage to the planet. rising global temperatures spell disaster for the world, they say. u nless disaster for the world, they say. unless quick action is taken by governments and individuals. melting arctic sea ice, rising sea levels and more extreme weather, already the result of global warming they say, but it will get much worse. the report sets out some incredibly difficult challenges. we will be asking how realistic it is to try to meet them. we'll also look at what individuals are being urged to do to help. also tonight. the second suspect in a salisbury nerve agent attack is named as a russian military doctor working for russia's intelligence of the wrist. the madrid dimmack mother 28 children thought to have died after suffering a severe allergic reaction to a sandwich. a spanish woman stolen from her mother by a doctor celebrates after he is found guilty. she is one of around 30,000 babies taken during a dictatorship. the

changing face of the royal ballet. we report on the drive to make it more diverse. coming up on sports day on bbc news, england striker harry kane is one of 11 premier league layers on a 30 man shortlist for the ball on‘dor. good evening. the world's top climate scientists are urging people to change the way their livestyles in order to avoid catastrophic climate change in the future. they warn that governments must make major policy changes now to reduce the impact of rising global temperatures. among the mesaures individuals can take are giving up meat, driving electric cars, and throwing less away. the scientists say a rise in global temperatures ofjust 1.5 degrees above preindustrial levels by the end of the century will mean rapid and unprecedented changes to all aspects of society. two degrees warmer

will mean millions of people losing their homes because of flooding as sea levels rise. but the intergovernmental panel on climate change says the world is currently on track for much worse — a rise of three degrees. 0ur science editor, david shukman, is in south korea, where the report was revealed. the warming of the earth is heading for levels that modern humans have never experienced. that's the unnerving implication of this latest report. it says the rise of the oceans could accelerate even with what sounds like a small increase in temperature. heatwaves are set to become more intense sooner than expected. and forest fires, combined with more warming, will have a profound impact on wildlife. when the report was unveiled at a press conference here in south korea, it came with a startling conclusion. if action is not taken,

it will take the planet into an unprecedented climate future, if we compare it to what has happened during all of human evolutionary history. the report says massive cuts are needed in the gases warming the atmosphere. that means turning away from fossil fuels like oil, because when they're burned, they give off carbon dioxide. vast new forests must also be planted to soak up the gas to have any chance of keeping global warming to a safe level. the report has sent a very clear message that if we don't act now and have substantial reductions in carbon dioxide emissions over the next decade, we are really making it very challenging to impossible to keep warming below 1.5 degrees. the report spells out that greenhouse gases must fall by 45% by 2030, just over a decade away. it says that up until 2035, it would cost 2.5% of global gdp — that's the total value of goods

and services around the world. not cheap, but the scientists say it will help. and renewable energy, they say, must produce 85% of our electricity by 2050. the obvious question that arises from the radical suggestions in this report is, is any of this remotely feasible? so many countries depend on coal, the dirtiest of the fossil fuels, and have plans to use more of it. and the vast majority of vehicles on the roads use petrol and diesel. 0n the other hand, there are some significant developments under way. the cost of renewable energy, like solar and wind, is falling, making it much more viable. and electric cars are set to become more mainstream, as the major new factories invest in them. but however this plays out, making a change on this scale is going to be a huge challenge. the key decisions on this now pass to the countries

that are the biggest polluters, like china and the united states. but the report also says that people going about their everyday lives have a say as well. we can all make choices about the energy we choose to consume. so we can make a move, through our choices of energy consumption to renewable energy, to provide the market for renewable energy. in terms of land, a lot of the land we use produces food. so we can make choices, dietary choices about what we choose to eat. around the conference centre, new skyscrapers and highways crawling with traffic. all this relies on fossil fuels. and like many development around the world, it will be incredibly hard to change. the scientists here have mapped out a way of minimising global warming. we'll now see what everyone makes of it. so what can individuals do to help fight climate change? 0ur science correspondent victoria gill has been looking at the small changes that could make a big difference.

as alarming as the message about climate change is, modern life keeps moving. so in the midst of an issue that's truly global, how can any one of us make choices to help the now urgent fight against climate change? one way, scientists point out, is to think more about how much carbon dioxide — the most prevalent greenhouse gas in our atmosphere — is emitted by the production of the food we eat. and that's something these shoppers are adding to their list of concerns. i think it's really important to try and reduce the amount of air miles and that sort of thing that our food is travelling. because it's not really doing anyone any good, is it, by using unnecessary fuel to buy food ? we check the label, and so often the film isn't recyclable. so that's something that is a concern and i think could be massively improved. i think the meat's completely cut down, totally. i bought chicken for my husband here, but red meat is a no—no. it's a total no—no?

you've cut that out completely? cut that out completely. and why is that, is it health, environment? health, basically. but that health—conscious decision chimes exactly with the environmental impact of meat and dairy versus vegetables. while animal products provide just 18% of our calories, they take up more than 80% of globalfarmland. and their production emits significantly more greenhouse gas. and then there's transport. while some people might be investing in an electric car, there are much cheaper decisions that every one of us can make every single day about how we move around. last year, transport accounted for more than a third of uk carbon dioxide emissions, a total of 124.4 metric tonnes. that, though, is a number that our decisions can influence. according to the world health organization, one passenger making a journey of a kilometre by car emits an average of 129g of carbon. a passenger travelling a kilometre by bus is

equivalent to just over 101g. a kilometre by bike emits no carbon at all. where possible, scientists say we should use an electricity supply from renewable energy sources, and as some businesses race to become carbon neutral, that's become a priority. we have a huge role to play in encouraging our suppliers to provide renewable green energy. we can also do that through on—site generation through solar panels and wind turbines, and also through what we sell our customers, such as lower energy consuming goods and services. what's now apparent is that the time we all have to make a positive difference is rapidly running out. victoria gill, bbc news. 0ur science editor, david shukman, is in incheon, south korea, where that report was unveiled. what the scientists are presented is a huge challenge — how realistic is it, though? well, i think the key

response 110w it, though? well, i think the key response now is from governments around the world, both in terms of what they think of this report, and then whether they might do anything about it. what's striking is that over the past week, many governments have had delegations here going through the report, scrutinising it a line byline, through the report, scrutinising it a line by line, challenging the scientists on their conclusions, and those delegations have included teams from donald trump's america, and also from oil—rich saudi arabia, and also from oil—rich saudi arabia, and they've had to give their approval before the report could be published. 0n the other hand, we know that donald trump wants to take america out of the paris agreement, the only deal there is to tackle climate change internationally. we know that the frontrunner in brazil's presidential election also wa nts to ta ke brazil's presidential election also wants to take brazil out in the same direction. 0n the other hand, you got major companies making big investments in solar and in wind — whether that is enough to do what the scientists think is needed is very unlikely. david shukman in south korea, thank you. the second suspect in the salisbury

nerve—agent attack has been named. sorry, my voice has gone! the investigative website bellingcat says the man who called himself alexander petrov and claimed to be a tourist is in fact a military doctor, employed by the russian intelligence service, the gru. the website says the 39—year—old is dr alexander yevgenyevich mishkin. here's our home affairs correspondent daniel sandford. the cathedral city of salisbury in march, and the two men suspected of poisoning sergei and yulia skripal with the nerve agent novichok. police believe the two men arrived in the country using false identities. the man on the left has since been identified as anatoliy chepiga. the man on the right has tonight been named by the bellingcat investigation website as a doctor, dr alexander yevgenyevich mishkin. bellingchat have unearthed these three pictures of dr alexander mishkin. the website says he trained in the military medical academy before being recruited by the gru, russian military intelligence. they also obtained this picture

of his passport in his real name. his false passport had the same date of birth, and he apparently even kept the first names of his parents in his false identity. the men gave an interview to russian state television under their false names, ruslan boshirov and alexander petrov. he on the right here is dr alexander mishkin. they're suspected of using this adapted perfume bottle to spray novichok on the door of sergei skripal‘s salisbury house. mr skrial and his daughter yulia ended up in comas in hospital before eventually recovering. but dawn sturgess, who handled the perfume bottle nearly four months later, died from the effects of the nerve agent. daniel sandford, bbc news. 0ur security correspondent gordon corera's with me now. so we now know the names of these two suspects, what difference will

that make on the big picture? well, the second gru officer to be identified, it took a bit longer for this website, bellingcat, to come up with a name, but they were able to do photo matching to identify him and put the names together. 0fficials i have spoken to, no—one is disputing the edification. what is disputing the edification. what is interesting is that he is a doctor, perhaps relevant to the application of the nerve agent, and more importantly these were not two sports nutritionist who came to see the cathedral. while it does not fundamentally change the story, i think it raises more questions about the russian narrative and the competence of the gru, that question again about why it has been so easy to identify their supposedly undercover intelligence officers, andi undercover intelligence officers, and i think one interesting aspect is that there are reports out of russia today that vladimir putin himself is very unhappy with the gru, because of this, because he himself was a former spy master, and these questions about its competence may mean there is a purge of its

ra nks may mean there is a purge of its ranks coming, at least according to some reports. gordon corera, thank you. president donald trump has said the sex assault claims made against his new supreme courtjustice, brett kavanaugh, were a "hoax" and "all made up". mr trump condemned democratic calls to impeach the judge as an "insult to the american public". justice kavanaugh will be sworn in later tonight. a 42—year—old mother to eight children has been named as the second person who died from a suspected allergic reaction after eating a sandwich bought from pret a manger. celia marsh from wiltshire collapsed in december. pret a manger says it was mis—sold yoghurt which was supposedly dairy—free by a third party. but the supplier strenuously denies that. duncan kennedy reports. celia marsh with her husband andy on their wedding day. one of a series of photos released tonight by her family. another shows celia, in the middle at the back here, sharing a christmas with four of her eight children. in a statement read by a legal representative, the family said they are still coming to terms

with what they call her sudden and unexpected death. she was a much loved mother, daughter, sister and wife. we miss her greatly, and we just want answers into how she died after eating lunch with herfamily. this was the kind of vegetarian sandwich, containing yoghurt, that celia marsh ate in december of last year. she bought it at this pret a manger in bath and after leaving the shop seemingly had an allergic reaction to it and later died. pret a manger says the sandwich was bought here, but the yoghurt used in it came from one of its suppliers called coyo. pret a manger says that it believes the yoghurt was guaranteed to be dairy—free, but says it has now ended its relationship with coyo and that they are taking legal action against the company. but tonight, coyo have told the bbc they have done nothing wrong. firstly, i would like

to say our sincerest condolences to the family and, secondly, the allegations made by pret are unfounded and highly misleading. after this second death comes after the case of 15—year—old natasha ednan—laperouse who died two years ago after eating a pret a manger baguette that she had bought at heathrow airport. after her inquest, the family welcomed pret‘s decision to change the labelling on its food. celia marsh's funeral took place injanuary. a spokesman for the coroner said they were still waiting for the results of pathology tests. duncan kennedy, bbc news. britain's biggest car—maker, jaguar land rover, says it's closing its factory in solihull for two weeks at the end of this month in response to weakening global demand. employees will be paid during the closure —

and no jobs will be lost. a drop in diesel sales — and tougher emissions standards — have hit the industry in recent months. an inquest has heard that the acting commissioner of the metropolitan police stayed in his car as an unarmed officer was stabbed during the westminster attack — because he had no protective equipment. sir craig mackey was leaving the houses of parliament in march last year when he witnessed the murder of pc keith palmer. richard lister reports. gunfire. the moment when the westminster attacker was shot dead and then, 20 seconds later, a dark blue official bmw is driven out of the gates of parliament. inside was sir craig mackey, the acting head of the metropolitan police who ended up leading the force's response. to ourfallen colleague, to our fallen colleague, pc palmer. but until his evidence today,

he had never publicly described what he himself had witnessed. by chance, when the attack started, sir craig was leaving a meeting at the house of commons. his official car had nearly left parliament when he saw khalid masood enter the gates and attack pc keith palmer. at this point, sir craig's car doors were locked. i saw two stab attempts into the torso of pc palmer, sir craig told the inquestjury. two absolutely determined stab movements. he then saw pc palmer run right past his car, followed by the attacker, khalid masood. he seemed absolutely focused on getting further down and attacking anyone that got in his way, sir craig said. he then heard the sound of khalid masood being shot by a close protection officer. sir craig said he tried to get out of the car, but a pc told him to shut the door, keep himself safe and leave. he was then driven away to start coordinating the metropolitan police response to the attack. richard lister, bbc news. scotland's first minister

nicola sturgeon says the scottish national party will vote down any brexit deal that would see the uk leave the eu single market and the customs union. at her party's conference in glasgow, she also said that her 35 mps would back a so—called people's vote, a second referendum on eu membership. here's our scotland editor, sarah smith. anyone here hoping to learn when there might be another independence referendum, has come to the wrong place, but there is another vote on offer, the snp will support a second referendum on brexit. i don't think it would be right for us to stand in the way of people elsewhere in the uk getting the chance to change their minds, and it would also, i think, be odd for us to not grasp an opportunity for scotland to reaffirm its vote to remain in the eu. you have got no guarantees you will not have the same outcome that you did in 2016, scotland votes to remain, but it is outnumbered by the vote of the rest of the uk, what could you do about that?

i've been very frank — it doesn't necessarily solve the problem that scotland finds itself in. yes, we can look at options that might protect scotland's position, but fundamentally, the only real protection for scotland against having decisions imposed on us against our will is for scotland to become independent. education matters deeply to the snp but they currently have a problem in the classroom. controversial computerised school tests they introduced for five—year—olds were voted down by the scottish parliament last month. that vote does not force the government to abandon the tests, even though every other party opposes them. these parties have no right to play politics with the education of children and young people in scotland. but will that parliamentary defeat change the policy? we will come forward with a proper consideration, of parliament's views, but also what we consider necessary to continue that progress in education. but it would be easier for you now to say that you will set out the details later but you agree

with the scottish parliament to halt primary1 testing, because that's what they voted for, and you think that parliamentary votes should be upheld. look, i will, we will reflect the parliamentary vote, we will reflect on the parliamentary vote, but we are considering how best to move forward. so you are considering defying the parliament? you can carry on with this as long as you like, i am not into say any more than i have. i believe very strongly that it is wrong to allow children to get to perhaps primary 4, primary 7, before we have an understanding that they are falling behind and need extra help. this poses something of a dilemma for the snp. they insist the will of the scottish parliament should be respected when it votes for an independence referendum, so it's hard to ignore it when they vote against one of their key policies, and education is the main priority for the snp. at conference, they cared deeply about the push for independence, voters care about what happened in scottish schools. sarah smith, bbc news, glasgow.

it's the last remaining stronghold in syria — where militants are still fighting president assad's regime. idlib province is now home to 3 million civilians among them up to 90 thousand anti—government rebels including extremistjihadists. president assad's forces were expected to launch a final offensive on idlib last month — but that was postponed after an agreement to create a demilitarized zone surrounding the rebel area. it was brokered by russia, which supports president assad, and by turkey, to the north. but president assad has not ruled out future military action, in his bid to restore complete control over his country. 0ur middle east editorjeremy bowen reports from the front line in idlib, a place fewjournalists have been able to get to. in this war most syrian christians have chosen silence or the regime. at st george's church, the local commander is proud that his mostly christian town has had a bishop since

the fourth century. and he is proud that in the fight to end the rebellion in idlib, christians from the town are in the front line. the guns are silent for now because turkey and russia want to set up a demilitarised zone to separate the regime and its enemies. 0n the other side, are islamist fighting groups. the christian commander says they are all dangerous fanatics, taking orders from western intelligence services, including britain. he says thejihadist extremists have a choice, give up their ideology or be killed. no deals? translation: no, they are terrorists. when they become humans, we will make a deal with them and we will do a deal when europe

and america stop their support and the gulf countries stop funding them and supporting the jihadi ideology in their heads. we drove along the front line around idlib province. village after village is in ruins. half of syria's population have lost their homes. the regime denies accusations that its forces are the biggest killers. the next stop was one more badly damaged ghost town. government forces pushed jihadists of the al—nusra front out of here earlier this year. at the school, newly reopened, the ministry was delivering supplies. the regime wants to show it is getting the country back. in the classroom are children too young to remember peace. only 100 families have come back here. for children who have seen a lot of war, school is a bright spot.

for a moment, the wrecked main street was busy before they melted away into the empty, damaged town. this girl hasjust started at the school. with herfamily, she arrived from idlib only ten days ago, a place of bad memories. one day, jihadist fighters came to their house. her father said they killed his son because his mother was an alawi, from the same sect as the president and from the alawi heartland. translation: i have a son. his mother is from latakia. i sent his mother and the other kids back to latakia at the beginning of the crisis. he was 14 years old, so he stayed with me. they cut his head off in front of me, in my house. he was 14 years old.

they cut off his head because his mother was from latakia. driving through that part of syria, from military positions to broken towns, in the rubble and pain an ending is in sight. the rebels are almost beaten. reopening this highway, the m5 is part of the plan to avoid a last battle in idlib. this is syria's main north south route, cut by rebels in idlib since early in the war. after all the years of killing and destruction, president assad and his allies are close to victory. but the president will never be able to say that he has restored sovereignty to the whole country while this road is still cut. that is why reopening it has become one of his major strategic priorities and it is shared by the russians as well. this is as far as you can go up

the highway on the regime side. the last syrian army post, looking across at territory held by the rebels. if the demilitarised zone does not work, the regime, the russians and the iranians might launch the offensive so feared by idlib's 3 million civilians. then there is the future. not deadly like war, but not cosy or reassuring. jeremy bowen, bbc news, on the idlib front line. in the first case of its kind — an eighty—five year—old retired doctor in spain has been found guilty of taking a newborn baby from her mother nearly 50 years ago, and having her illegally adopted under a practice targeted at political dissidents during general franco's dictatorship. but a court allowed the former doctor to walk free, as lucy williamson reports from madrid. sometimes history is told through a single face, a single trial.

the story of ines madrigal was recognised by spain for the first time today, a glimpse into the country's difficult past. dr eduardo vela was found to have stolen the newborn ines from her mother 49 years ago, faking her birth certificate and giving her to another couple as a gift. but, despite committing the crimes, dr vela walked free today, pending the prosecution's appeal, because the court decided it was too late under the law to convict him. translation: i don't mind that he's not going to jail, that's not the most important thing. it will be very difficult for him to leave his house, because everyone will recognise him. everyone will know what he did. so, for me, he's been condemned anyway. the trial of dr vela has broken decades of silence on what campaigners say is a dark part of spain's history.

they say there are tens of thousands of children like ines who were stolen from their mothers straight after birth by medical staff, or members of the catholic church. but the court's verdict today may mean that none of those who are guilty ever go to jail. campaigners believe the initial targets were political opponents opposed to general franco's post—war dictatorship. but later included poor and unmarried mothers, whose children were believed to be better off with wealthy catholic families. it continued as a lucrative trade in child trafficking after franco's death, campaigners say, until at least the late 1980s when the adoption law was changed. paula's baby disappeared immediately after birth 44 years ago, before she was able to give her first—born child a name, or even learn its gender. translation: every year i write a letter to him or to her. you were nine months

in my belly, i say. those five seconds when i glimpsed you, i've loved you ever since. you were going to be my first child. i was full of hope. but mothers across spain are celebrating this first step in acknowledging the past. and a justice that, for now, is more about truth than punishment. lucy williamson, bbc news, madrid. ballet is seen by many as the most elite and least diverse of all the arts. but at the royal ballet, the two dancers most recently promoted to principal ballerina are both mixed race. they say they represent a changing ballet world as lizo mzimba reports. one of the royal ballet's most recent promotions to the top level of principal ballerina, yasmine naghdi, is half belgian, half iranian. made principal at the same time, francesca hayward is half

english, half kenyan. exceptional talent and long hours of preparation have helped them both reach the most senior positions in the company. they also know their backgrounds have huge symbolic value. i feel very proud that i can inspire the younger generation to strive to do what we do, and that's what this is about is inspiring younger generations. i'm really proud to be here, to show that, you know, it is literally for anyone, of any colour, any background, no matter how much money you have. as well as showcasing diverse talents at the very top of the company, the royal ballet is also working hard to plant
