this programme contains flashing images. tonight at ten, at the world economic forum in davos, president trump hits out at climate campaigners, calling them "prophets of doom". the president arrived in switzerland, as his impeachment trial was getting under way, back home in washington dc. he came to davos, with a provocative message for the world's climate experts, who are calling for urgent action to save the planet. we must reject the perennial prophets of doom and their predictions of the apocalypse.

among those present was the teenage climate activist, greta thunberg, who tore into political leaders, and the economic priorities driving their decisions. you say, "just leave this to us, we will fix this, we promise we won't let you down, don't be so pessimistic." and then... ..nothing... ..silence. we'll have the latest from davos and from washington, on the impeachment process against president trump. also tonight: in china, experts warn that a new respiratory virus can be expected to spread right across the country and into other neighbouring states within days. the duke and duchess of sussex have issued a legal warning, after the latest photographs by paparazzi were published around the world. and in australia, after the devastation of months of wildfires — we report on the signs of hope emerging at long last. and coming up on sportsday

on bbc news: a busy night in the premier league, but will manchester city miss the chance to close the gap at the top? good evening. at the world economic forum in davos, president trump has directed some of his hardest criticism to date at climate campaigners, dismissing them as "prophets of doom", and he promised to protect the us economy, which is fuelled by cheap supplies of gas. sustainability is the main theme of this year's forum, and among those listening to mr trump was the teenage climate activist, greta thunberg. she later tore into political leaders, asking if it was worth risking a climate disaster in order

to safeguard economic interests. mr trump was speaking hours before his impeachment trial began in the us senate in washington dc. more on that in a moment — but first, james robbins reports from davos. getting away from it all? donald trump has flown over 4,000 miles from washington to the alpine heights of davos, hoping to look more like a president on the world stage, less like a defendant back home. he's treading carefully on all the ice and snow — any fall here would look terrible. but will this gathering of the world economic forum, 5,000 feet up in switzerland, give an embattled president the high ground he craves? even without impeachment, he is way out of step with the main goal of this meeting — to do much more to tackle global temperature rise. but to embrace the possibilities of tomorrow, we must reject the perennial prophets of doom and their

predictions of the apocalypse. they are the heirs of yesterday's foolish fortune tellers and i have them and you have them and we all have them and they want to see us do badly, but we don't let that happen. being here today in switzerland and not in washington, the president may feel he is among friends — surrounded by more than 100 fellow billionaire — but, in truth, he is in a much more vulnerable and uncomfortable position than any of them. i'm a very big believer in the environment, we're now are doing extremely well in the united states, but what i want us to have cleanest water, the cleanest air and that is what we are going to have and that's what we have right now. so, who are the world's biggest polluters? the us is the second largest producer of c02, accounting for nearly 15% of global emissions, but china is responsible for almost double that. the next biggest emitters of carbon

dioxide are india, russia and japan, which produce another 15% of emissions between them. britain accounts for 1.1% of the total. one of donald trump's fiercest critic is also here in davos. greta thunberg, teenage swedish activist, wants to hold everyone to account on behalf of her generation, accusing governments worldwide of empty promises. the fact that the usa is leaving the paris accord seemed to outrage and worry everyone and it should. but the fact that we are all about to fail the commitments you signed up for in the paris agreement doesn't seem to bother the people in power even the least. president trump will be using the rest of his time in davos to focus on one—to—one meetings with other world leaders. he will be discussing everything from trade disputes to the huge tensions in the middle east,

but the long shadow of events in washington still seems to reach even to switzerland. james robbins, bbc news. as we heard, president trump was speaking in davos hours before his impeachment trial began in the us senate. it's only the third time in american history that a president has faced an impeachment trial. the process involves several stages. it could, in theory, lead to president trump being removed from office. the process started in the lower house, the house of representatives, where two charges were brought against him. the actual trial takes place in the senate, the upper house, and that's the one that has already started today. the chamber of 100 senators acts as a jury — 53 senators are republican, and 47 are democrats. a two—thirds vote is necessary for a president's removal, it's never happened before. 0ur north america editor jon sopel has the latest.

here thee, all persons are commanded to keep silent on pain of imprisonment. 1868, 1999 and now 2020, for only the third time in american history, the sergeant at arms tells senators on pain of imprisonment that they must maintain silence in the trial of a sitting president, the asth, donaldj trump. presiding over it the chiefjustice, john roberts. but all for this being a judicial process, it is really raw politics. the first person to be called was the senior white house counsel acting as the defence. we believe that once you hear those initial presentations, the only conclusion will be that the president has done absolutely nothing wrong. and that these

articles of impeachment do not begin to approach the standard required. the central argument is whether witnesses should be allowed. the republicans want the trial to be done and dusted in a little over a week, with no one called to give evidence. the chief prosecutors is adam schiff. he says that would be a travesty. if the defendant is not allowed to introduce evidence of his innocence, it is not a fair trial. so too for the prosecution. if the house cannot call witnesses or introduce documents in evidence, it is not a fair trial. it is it not really a trial at all. trump may be with the global elite, but he is watching is what happening in washington. it is a hoax, it goes nowhere because nothing happened. the op only thing we have done is a greatjob. we have the greatest

economy over in our greatjob. we have the greatest economy over in our history. the trial will last for at least a week. there will be questioning. all of this will be conducted with the strictest rules of behaviour. but on the the cable news networks it is playing ought and here it is mixed martial arts with no rules. this fights for public opinion is such as important as donald trump eyes re—election later on this year. the extents to which this is a political process was underlined a moment ago and there was a vote on whether to subpoena votes from the white house. the vote fell on strict party lines. it will be interesting to see what happens when they come to vote, probably next vote, on whether witnesses should be called. even if witnesses should be called. even if witnesses are called, it is hard to believe it will fundamentally ator the dynamics that donald trump will not become the first president to be

forcibly removed from office. as to the question of whether he becomes the question of whether he becomes the first impeached president to win re—election, well that is still open. thank you, jon sopel. a case of the new virus spreading across china has been reported in seattle, in the united states. the man had recently returned from china. six people are now known to have died and more than 300 have been infected by the coronavirus, which can cause respiratory problems. 0ur medical correspondent fergus walsh is here. how concerned should people be? well, in the uk for example, there is no cause for concern at all. that largely applies outside of china, this american patient for example is responding well to treatment. having said that, any new virus which jumps the species barrier from animals to humans is a cause for concernments

we don't know what the animal reservoir is for this virus. it has been linked to a sea food market, but it resembles a virus found in bats. it can jump from person—to—person, but it doesn't seem to be particularly contagious and all the people who have died had underlying health problems. so they had weakened immune systems. tomorrow, the world health 0rganisation will have to decide whether to declare the virus a global public health emergency. they have done that before in the case of other viruses. but it is not a given. they could issue travel advice and restrictions and they didn't do so in the case of a middle eastern virus that jumped didn't do so in the case of a middle eastern virus thatjumped from camels to humans. so they may decide to watch and wait for this epidemic

to watch and wait for this epidemic to spread and see how it develops. thank you. the nhs in england faces more than £4 billion in legal fees to settle outstanding claims of clinical negligence, according to figures obtained by bbc news. the total estimated cost of all unsettled claims now stands at £83 billion — it's more than doubled in four years. the department of health has pledged to tackle what it calls "the unsustainable rise in the cost of clinical negligence", as our correspondent angus crawford explains. brother, son, grandson. this is hayden. wow. a video filmed when he was just hours old. but later, he was rushed to hospital. and after a failure to treat a virus, which attacked his heart, he died there. he lived forjust six days. every parent's worst nightmare. we had to sit there and watch our son slowly die in front of our eyes, literally.

to find out the truth, they felt they had no choice but to sue. you can't bring that person back, nothing is going to bring them back, and the only thing that helps, is to have acknowledgement that they existed. that they mattered. and answers. i haven't really thought about it as suing the nhs. i felt about it as kind of fighting for a voice for hayden, and fighting for, you know, acknowledgement of his life and his rights. i don't think we would have got the answers we had any other way. the hospital did eventually admit liability, years later. that picture is being repeated across england. payments for clinical negligence have doubled since 2015. last year, the nhs paid out £2.3 billion. but the total cost of outstanding claims now stands at a staggering £83 billion, and we've learned legal fees make up 11.3 billion of that. compensation comes from a central fund, topped up every year by the hospitals themselves.

the rise in pay outs down to failures in maternity care. lifetime support for babies, injured at birth. more complex cases, and a change in how claims are calculated. but lawyers for patients warn safety failings are really the key issue. you've got patients who are injured negligently and that's why they should be compensated. what we should be looking at is improving patient care and patient safety. we would then have less injured patients and the costs of litigation will then come down. the government says it's committed to tackling the unsustainable rise in the cost of clinical negligence, and its ambition is for the nhs to be the safest health care system in the world.

but hayden's death is evidence of a system that failed. 0ne his parents believe is in urgent need of reform. there is a death and you pay. there's a death, you pay. there's an injury, you pay, and they're not actually fixing the source of the problems, so it is just going to be repeated. angus crawford, bbc news. 0ur health editor hugh pym is with me. when we look at the potential size of this bill, what is the kind of calculation that ministers and nhs officials are making here? it is a difficult balancing act to make sure patients and their families are properly compensated if there is negligence and making sure the nhs is prudent with its many. 0ne negligence and making sure the nhs is prudent with its many. one reason for this, people are living longer and that means a lifetime of care will cost more and lawyers doing no

fee deals with patience are pushed up fee deals with patience are pushed up costs. a resolution is trying to get people to do more mediation with the nhs. the department of health said it wants to fix costs for certain low value claims. maternity damages pay—out to make up about half of the total as we have seen with the shrewsbury and telford maternity units scandal, hundreds of cases have not been settled. 0ne person said, what if long—term health continues to deteriorate, and they decide to sue the nhs? hugh pym, thank you. the mpjess phillips has dropped out of the labour leadership contest, leaving four candidates in the race to succeed jeremy corbyn. the birmingham yardley mp said the next leader had to unite the whole labour movement, and she said that person wasn't her. emily thornberry, sir keir starmer, rebecca long—bailey, and lisa nandy are still competing to be labour leader, with the result on 11th april.

the gmb union today came out in support of lisa nandy. the duke and duchess of sussex have issued a legal warning the new delay for the boeing 7117 max jet is thought to be of a software floor. it was grounded back in march of 2019 after two deadly crashes in which 346 people lost their lives. the duke and duchess of sussex have issued a legal warning after the latest photographs by paparazzi were published around the world. prince harry and his wife meghan say photographers are now permanently camped outside their home in canada. sophie long is on vancouver island.

this is what meghan and harry moved to canada far, a peaceful life by the pacific coast. but they said they found photographers hiding in bushes and an alarming level of paparazzi activity around the home they are staying in. pictures were published around the world of meghan out walking yesterday. she was with their young son and two dogs and looked happy and relaxed as she waited for harry to arrive. but the couple say she did not consent to being photographed. their legal team said the paparazzi have set up a permanent camp around the property and try to take pictures inside using long lenses. harry has only been here on vancouver island for less tha n been here on vancouver island for less than 24 hours. he arrived last night to be reunited with meghan and archie. they should have been the first day of their new life together. instead it has involved lawyers, legal warnings and it all very welcome reminders of home and what the couple were trying to

escape. the personal speech harry may before leaving the uk, talked about the powerful force of the media and the queen talked about the intense scrutiny of the couple had been subjected to. even though they have taken that step back from royal life, even though they have travelled thousands of miles, it seems they are yet to find a peaceful life, free from intrusion, they hoped to see here. sophie long, thank you for the latest from vancouver island. universities have had a tough time of it financially, in recent years. and one way they've coped is by attracting increasing numbers of foreign students. more chinese students than ever are studying here — up by a third in just five years, according to the latest figures. they are the largest single group with 120,000 students. it's a lot more than india, which comes second, and almost as many as all eu countries combined. so they produce something of a financial windfall, but some mps are now warning about the influence of the chinese government on campus. as part of our series

on immigration, our education editor branwenjeffreys has been to the university of liverpool, which has the highest proportion of students from mainland china. # the sun never goes down until night. ..# my name is deng renwei. in the uk, people call me kevin here. # it's liverpool. ..# music brought him to study in liverpool. now he's writing songs about the city for his band. kevin told me being a student here has given him a different perspective. it makes me think things more objectively, especially when it comes to a global matter. i won't... i won't see it only in a chinese perspective. almost one in five students at this university are from china, paying fees two or three times higher than uk students. in a uni lab, yang bai is working on clean energy,

a graduate doing research. the chinese government is paying for him to be here. before i came here, i'd never seen a laboratory that looks like this. it's amazing. so this is a world—class facility? yes. firstly, iwould bring the future to real life. so the science here is being carried out across two countries. china has almost unrivaled resources to put behind research. the chinese government is paying for 40 phd students to use the world—class facilities here. it's part of a much wider collaboration, but it's a relationship that some believe has to be handled with care. so would the university risk offending the chinese government? would a pro—democracy speaker from hong kong be welcome? we would want to be sensitive to the relationships that we have with any partner. but, you know, we are part of the uk higher education sector.

freedom of speech is really important to us. and yet mps are genuinely worried that universities are being naive in the way that they are engaging with china. i don't think we're influenced in a negative way. china is now the second largest research and development economy in the world. you know, they have a quarter of all research and development scientists and researchers in the world. you know, we cannot afford to ignore the contributions that chinese research can make. when democracy protesters took to the streets in hong kong, there was an impact on uk campuses. i travelled to another part of the country to meet hong kong chinese students. if i get identified by the chinese embassy or the chinese government, then i might put the safety of relatives i have living in china under threat.

they say they've been intimidated by mainland chinese students. i've had death threats on mainland people's group chats of them saying that they want to kill me. 0n things that i've put up on the university campus, and they're saying that they'll bring knives to kill me. and they've also harassed me by taking photos of the stuff i put up and where i stay. young people, thousands of miles from home, theirfamilies paying for a british education. but does their government now have a bigger say on uk campuses? branwen jeffreys, bbc news. and online, there's a new bbc briefing guide on immigration. there's renewed debate over how global tech firms should be taxed at the annual meeting of the world economic forum in davos. the uk plans to levy a 2% tax on search engines, social companies and online marketplaces from april,

but they're being urged to instead work together with other countries to come up with a solution. 0ur economics editor faisal islam is in davos for us. in your view, what kind of pressure is the uk coming under now?m in your view, what kind of pressure is the uk coming under now? it is one of the thorniest issues in global economics and therefore the world economic forum. the taxation of these global tech giants. the uk has a long—standing solution for two yea rs has a long—standing solution for two years that they will go ahead with a unilateral tax on the likes of google, amazon and facebook of 2% of april of this year. it is in the finance bill going through the commons and the reference was in the conservative manifesto. but as this happened, the head of the global body looking for a global solution has told the bbc the uk should hold fire on its tax. this comes on the back of an agreement we think will be struck tomorrow between the us and the french to delay their

version of this digital services tax and that has led the us treasury secretary to say that if anyone goes ahead with it, they will face president trump's paris. sajid javid will have to sort this out tomorrow. thank you very much. in australia, where bushfires have been raging around coastal regions since september, claiming dozens of lives, destroying thousands of homes and laying waste to millions of hectares of woodland. despite heavy rain and hail in some areas over the weekend, many of the fires are still burning. but as our correspondent nick beake has been finding out, in the midst of devastation, there are some signs of hope at last. in this silent bleakness, it's hard to find comfort. but look closer. new hope. new colour. new beginnings. these brutal fires may have scorched so much of the bush in this vast country, but already there is life once more.

a month ago, this is what confronted jez and deb. they watched as the flames raced across their land. so, the fire came over the top of this ridge, and then jumped over the gully and roared up this side. much of the thick vegetation was incinerated, but now... even after all the fire, you can see that after a bit of moisture and a bit of rain this angophora has started to shoot. what do you make of that? that's pretty incredible, to be honest with you. jez and deb have been looking for signs of recovery. this is a place that's been stripped bare, but not destroyed. these trees actually need the fire to regenerate. the seed pods here open with the heat, so it's a good thing that the fire goes through for this banksia tree. you have got to look for the best anyway, so yes, we'll use this as a restart,

and try and create a place better for the wildlife and all vegetation and such. we are seeing signs of new life, all across fire scorched australia. flickers of hope, after these darkest of months, and it's a much needed tonic for the thousands of people who are now trying to rebuild their own lives. he does like to get out of his bag and stretch his legs a bit. and for some native animals who survived the fire, including jake, a gentle reintroduction to their transformed habitat. he's not a wallaby, and he's not a kangaroo. he's a wallaroo. there may be strength in adversity here, but no—one wants to be rebuilding time and time again. i hope that in the future this is a little bit of a wake up call. it's never too late to change the way that we do agriculture and do coal mining and that sort of thing in australia. so yes, you can see new life here, but with other fires still burning it's a new urgency that's needed

to protect the future of this land. nick beake, bbc news, new south wales. that's it. now on bbc one, time for the news where you are. have a very good night. good evening, welcome to sportsday. i'm adam wild. coming up, manchester city have reduced the gap at the top of the premier league just a little on a night of extraoridnary drama. the rfu says it's not ruled out england selection for saracens players who move abroad after the club's relegation.

dart takes flight at the australian open. qualifier harriet dart is through to the second round on an otherwise disappointing day for the brits in melbourne. welcome along. it's been a night of high drama, late late goals and some big results in the premier league this evening. let's start at bramhall lane where perhaps the surprise success of the season sheffield united were taking on the reigning champions manchester city. rhia chohan was watching. these are the nights ramon lane have been waiting for, sheffield united riding high on the table looking for a big results against manchester

city. at times, the first half felt like it local derby, big challenges and temperatures made appearances and temperatures made appearances and city pushed hard but dean henderson, the manchester united and loney made light work of saving close range efforts. after he was tripped, henderson added to their frustrations by sending his penalty away which followed. henderson was clearly off his line in the manchester city bench were incensed as it was not in order to be taken but was worth a little book after the keeper pots like excellent performance that far. guardiola process i should've been in the lead. but then united missed a close chance. they only need a margin to win games at this and when sergio aguero came off the bench, he just need to millimetres. they needed to work for at, that would do for it. rhia chohan, bbc news. so, perhaps they are just playing for a champions league spot but city
