on electricity, the impact on schools, the impact on hospitals. we'll be looking at the latest figures in more detail. also tonight... a once—in—a—generation clinical trial to find possible treatments for motor neurone disease, which affects thousands of people in the uk. i've lost... the backlash against the government's rescue plan for flybe as rivals accuse ministers of misusing public funds. in canada, meghan makes a public appearance as her father reveals he could testify against her in a legal battle with the mail on sunday. and warming up for the australian open next week, some of the biggest names in tennis come together to raise money for those affected by the bushfires. and coming up on sportsday on bbc news — we'll bring

you all the latest from the fa cup‘s third round replays. can manchester united hold off wolves at old trafford? good evening. the past decade was officially the warmest on record. figures released today paint a stark picture of rising global temperatures and the impact that human activity is having on the planet. the data compiled by british and american scientists, including the met office and nasa, also reveal that 2019 was the second warmest year based on data going back to 1850 and temperatures are set to rise further unless action is taken. 0ur science correspondent rebecca morelle has more details. from the heatwaves across europe

that saw the uk hit an all—time high of 38.7 degrees, to greenland, which broke the record for the most ice lost in a single day, and our oceans, which are now the warmest they've been in human history, 2019 was a year of extremes. and this map shows how global temperatures have changed over time. each decade from the 19805 has been warmer than the decade before. the last ten years have now been confirmed as the hottest since records began. scientists say humans are to blame. carbon dioxide levels are at the highest that we've ever recorded in our atmosphere, and there's a definite connection between the amount of carbon dioxide and the temperature. we are seeing the highest global temperatures in the last decade, and we'll see more of that. as carbon dioxide continues to grow, we will see global temperatures increasing. measurements taken at observatories like this one show that our planet is heating up fast. already, the world's temperature has

risen by 1.1 degrees above preindustrial levels. scientists though say we need to stop temperatures from rising above 1.5 degrees to stop the worst effects of global warming but, with our current climate policies, we are heading for more than three degrees, and that would bring unprecedented changes. higher temperatures will mean more heatwaves and droughts, sea levels would rise and rain would intensify, bringing more floods like the ones that hit yorkshire last year. what we have to remember is that the climate crisis is going to affect our economy across so many different dimensions, so it's going to impact on health and already it's impacting on health, it's going to impact on food supply and food security, it's going to impact on infrastructure, so we talk about critical infrastructure, the impact on electricity, the impact on schools and hospitals. climate awareness is now higher than ever before, but scientists say it's action

that's needed, by cutting greenhouse gas emissions to net zero by 2050. this, though, will require huge changes, from swapping fossil fuels to renewables to drastically reducing how much we fly and rethinking the food we eat. but the extreme conditions show no signs of letting up, especially with australia's fires, which continue to burn. the met office is already forecasting that 2020 could be another record—breaking year. rebecca morelle, bbc news. the group that owns british airways has filed an official complaint with the european commission related to the government's rescue plan for the regional airline flybe. the plan could mean that the airline defers a big tax bill for air passenger duty and flybe‘s rivals are claiming that's a misuse of public funds. the government says any changes to taxes would apply to all airlines as our business editor simonjack reports. flybe‘s rescue by the government was greeted with relief

and gratitude by workers, travellers and regional airports. today came the backlash from the rest of the industry. although airline companies have long argued for the newly promised reduction in airport passenger duty, allowing flybe to delay payment of millions of tax arrears drew fire from competitors. we would not support any state funding or state support to any carrier, any airline at all, because we believe that that is misuse of taxpayers‘ money. particularly when the company are, you know, backed by well—funded companies also in the first place. you've been calling for apd, passenger duty, to be cut for some time. they've done you a favour, haven't they? i don't see it in that way. we have always argued that, for instance, apd should be revised to more and better reflect the efficiencies of the operations that different airlines have. it is one of the highest passenger taxes in the world.

we don't think that is designed in an appropriate way. and it's not linked at all in how you decarbonise the aviation industry. ba supremo willie walsh has lodged a complaint with the eu, saying the taxpayer was picking up the tab for the mismanagement of the airline, adding, "this is a blatant misuse "of public funds". the government insisted the deal was fully compliant with state aid rules and preserved regional connectivity across the uk. flybe is the biggest operator from these airports, spanning scotland's north—east, to england's south—west. reducing taxes on domestic flights could make those journeys cheaper, but, at a time when many argue we should be flying less, should we? no, i think that connectivity around the country is incredibly important. take the flights to the scilly isles, for instance. it's very hard and takes a long time to get to the scilly isles if you're not in an aeroplane. and being able to connect different parts of the country is important. at the same time, flying has already decarbonised and can decarbonise more.

but flying still uses a lot of fuel and emits a lot of carbon. climate scientists say ministers are sending mixed messages. the government has been deeply inconsistent because you have to remember, they are mandated by uk law to reduce the carbon footprint of this country to zero by 2050 or earlier, if possible. and, actually, flying is one of the most carbon—intensive forms of transport we have, so they should be doing everything they can to reduce the amount of flying we do. the flybe deal poses a lot of questions. how did it get in such trouble less than a year after its last rescue? will this fix work, and does this intervention set a new precedent? the government thinks it's done what it can and what it should have, but that question, like flybe, remains in the air. simon jack, bbc news. motor neurone disease is a devastating illness affecting the nerves in the brain and spinal

cord which direct muscle movement. it's always fatal and there is no known cure. but now people with the disease are being invited to sign up for one of the most comprehensive clinical trials in a generation. for the first time, it could give hundreds of people across britain the chance to test potential treatments. around 5,000 people have motor neurone disease in the uk, with some 1,500 people diagnosed every year. it's estimated that 50% of those diagnosed die within two years. 0ur health correspondent, dominic hughes has this exclusive report. for three—year—old anna, life with mum and dad must seem pretty normal. a loving family, safe and secure, but there is a deep sadness here, even fear. mum ruth williamson has motor neurone disease, an illness that, day by day, is stealing her future.

ruth was an active runner and cyclist when she was diagnosed a little over two years ago. now, the illness is affecting not just her speech but also her ability to walk. but, at edinburgh university, scientists are preparing to launch one of the biggest mnd drug trials ever seen in the uk.

motor neurone disease sees muscles waste away after a loss of nerve cells that control movement, speech and breathing, so this trial will test new treatments, but also look at drugs already being prescribed for other illnesses. this research matters because, as it stands, there is currently no effective treatment for motor neurone disease, let alone a cure, but repurposing existing drugs that are used to treat conditions such as alzheimer's disease or even anxiety and depression, well, that opens up new possibilities. these are medicines which have been shown to be effective in other brain disorders and, because they share common ways in which the brain doesn't work properly, we can look at these drugs and see if they work in motor neurone disease. and, for patients like alan, diagnosed three years ago, taking part in the trial offers the chance to contribute towards a better understanding of the disease. the hope is something that's a real positive, so i think, with having a trial now,

we can see something that we can get some hope and strength from, so i think, as participants, we can help move science forward, so that's the one thing that we will be learning. for this family, ruth, her husband, scott, and anna, there will be some tough days ahead, but this trial at least offers something positive in the face of a cruel and indiscriminate disease.

it was a real privilege to meet with ruth and her family and it was a real privilege to meet with ruth and herfamily and i don't mind admitting it was very emotional interview for all of us and that is the thing about motor neurone disease. when somebody gets that diagnosis, they pretty much know the illness will take their lives and thatis illness will take their lives and that is the point about the clinical trial. yes, it isjust that is the point about the clinical trial. yes, it is just a trial and it is early days but it does offer that glimmer of hope and it is designed to run for years so we intend to follow it as it progresses and bring you the results here on bbc news. dominic hughes with exclusive report. the number of cases being looked into by an independent inquiry into maternity care at shrewsbury and telford hospital trust has risen to 900. they include deaths, serious injuries and where families have concerns about care they received. some date back a0 years.

the duchess of sussex is facing the prospect of seeing her estranged father, thomas markle, testifying against her at the high court. the case has been brought by meghan against the mail on sunday for publishing a letter she'd written to mr markle. meghan‘s half sister samantha told bbc news that their father would give evidence in the paper's defence if he was asked as our royal correspondent nicholas witchell reports. markle versus markle. as if the events of the past week haven't been enough, there is now the prospect of the relationship between meghan markle and her estranged father, thomas, being dissected at the high court in london. the reason — meghan is suing the mail on sunday for breach of privacy after the newspaper published a letter she'd sent her father. mr markle had given the letter to the newspaper. unsurprisingly, in preparing its detailed defence, the mail on sunday regards thomas markle as its principal defence witness.

meghan‘s half—sister samantha has told the bbc, "if he is called to give evidence, he will come." meghan‘s relationship with herfather reached crisis point at the time of her wedding. mr markle, who lives in mexico, developed heart trouble and was unable to attend. now the mail on sunday's lawyers have revealed text messages between the two of them. in one, mr markle says... so, what should meghan do? media lawyers say the answer is obvious. you really don't want to go down this particular road. whoever is advising them is frankly not doing them any service whatsoever. and it's, i think, important to note that the queen's solicitor started off dealing with this case and he's no longer dealing with this case. the royal show goes on.

william and catherine were in bradford today, taking part in a discussion about keeping communities together. sometimes, trying to get people to understand that it's ok to have these challenges and we just need to deal with them. 0n the snowbound west coast of canada, meghan was photographed yesterday at a local women's centre. in 2022, the invictus games... harry, who appeared in an invictus games video, which was released tonight, is expected to join her in canada some time next week. they face many questions, one of them is whether they want to begin their new life with a court case which would make headlines around the world. nicholas witchell, bbc news. a man has been arrested in pakistan in connection with the murder of a policewoman in bradford in 2005. sharon beshenivsky was shot dead outside a travel agency while responding to an armed robbery. 71—year—old piran ditta khan appeared in court today in islamabad. 0ur north of england correspondent judith moritz reports.

when sharon beshenivsky was shot in the line of duty, she'd only been a police officer for nine months. the new recruit had been responding to a robbery at this travel agent in bradford. her shift partner was also shot but survived. her widower, paul, was left to care for their young family. pc beshenivsky was murdered on their daughter's fourth birthday. i loved her very much and, you know, i just... she was very full of herself in what she did and enjoyed herjob to the full, sort of thing, enjoyed life to the full. today, paul learned that after all this time, a new arrest has been made. i just feel like it's reliving it all over again, it's just bringing it all back to light and i'll be glad to see the back of it. the 15th anniversary of pc beshenivsky‘s murder is later this year and west yorkshire police say they've never closed their investigation. though six men have already been

convicted in connection with what happened here, the police say they have kept looking for the seventh, piran dhitta khan. in 2016, the police said they'd pay £20,000 to anyone with information leading to his capture. yesterday, mr khan was arrested in pakistan. he appeared in court today and efforts are now under way to return him to the uk. there is a lot of work to be done yet. there's an extradition process and then the investigation‘s got to be put together to be presented before the courts, for them to make a decision. the police say this is a major development in their long—running investigation but they're still mourning the loss of their colleague and they're working to getjustice for her. judith moritz, bbc news, bradford. the us and china have signed a partial trade deal aimed at easing the 18 month trade conflict between the world's two biggest economies.

president trump and china's vice premier attended a ceremony at the white house. mr trump said the agreement was a ‘momentous step towards a future of fair and reciprocal trade‘ between the us and china. our global trade correspondent dharshini david has this assessment. from american farmers producing soya beans or pork, to car manufacturers and chinese factory workers making our electronic gadgets, these are the people and businesses bearing the brunt of the trade war. it is their goods on which extra charges or tariffs have been imposed and those costs have added over $800 to the average american family‘s annual bills and, according to one estimate, cost up to 300,000 us jobs. with the pain mounting for those the trade dispute was meant to help, president trump has agreed a truce. today we take a momentous step, one that has never been taken before with china.

towards a future of fair and reciprocal trade as we sign phase one of the historic trade deal between the united states and china. the relief may be mutual. the chinese people have seen their incomes grow at the slowest rate in three decades, in the face of the war triggered by president trump to protect american jobs and companies from what he viewed as unfair competition. but is this a victory or a climb—down from the us president, and is the relationship between the superpowers being significantly overhauled? well, china has promised to buy another $200 billion worth of us agricultural goods and industrial goods worth some $75 billion. but will it actually keep to those promises? in return, the us is halving its tariffs or import taxes on $120 billion worth of chinese goods but it will continue to levy 25% tariffs on products worth

another $250 billion. meanwhile, president trump‘s biggest and thorniest complaint, that china unfairly subsidises its industries, has not been resolved and it is unlikely to be any time soon. it will take a number of months for us to see how the agreement is working out in practice and then, with respect to the remaining issues that are supposed to be in phase two, i think that is frankly going to take quite a long time because i think our governments are still very far apart. with an american election looming, this ceasefire may be as much political as economic. president trump is yet to achieve his ambition of rewriting the trade rule book. those hoping that the uk and america can forge a mutually beneficial relationship after brexit, will be watching closely. dharshini david, bbc news. the us house of representatives has voted to send two impeachment charges against president trump to the senate where he will be tried.

the house also approved seven democrats who will act as the prosecutors. the hearing due to begin next week will be only the third ever impeachment trial of a us president. mr trump denies any wrongdoing. the government is to give the executive in northern ireland and extra million pounds —— £1 billion. another £1 billion will be given and the government said the additional money announced tonight will have to transform the public sector but the local parties in the power—sharing executive had said they were hoping for more money. in the philippines, scientists say a ‘hazardous eruption‘ is now imminent as the taal volcano continues to expel ash into the sky. more than 40,000 people have fled the nine—mile danger zone around

the volcano, which is 60 miles south of the capital, manila. experts have warned that an eruption could set off a tsunami from the lake surrounding the volcano. russia‘s entire government has resigned hours after president putin proposed sweeping constitutional changes that could prolong his period in power. if approved by the public, the proposals would transfer some power from the presidency to parliament and boost the role of the state council, which mr putin chairs. 0ur correspondent steve rosenberg is in moscow tonight. steve, i suppose the question is, what is mr putin up to? yes, absolutely. i mean, iwish i knew. people are scratching their heads here. the point is that in four yea rs here. the point is that in four years time, president putin will be constitutionally obliged to leave office, to leave the presidency and for months now there has been speculation that he would try to change the constitution in order to

retain influence or to stay in power, if not as president perhaps in some other role. perhaps as head of national security council or head of national security council or head of the state council here. so the proposals outlined today are not com pletely proposals outlined today are not completely unexpected. what has surprised everyone is the resignation of the government. but again, that is most likely part of a wider kremlin plan, to which we are not privy. in short, this was, i think, a significant day in moscow because it feels as if big pieces of an important jigsaw puzzle because it feels as if big pieces of an importantjigsaw puzzle had been put in place and although we do not know what the final picture will look like, i think the chances are vladimir putin will be part of it. thank you. in australia, rafa nadal, roger federer, serena williams and novak djokovic have all been playing a charity match in melbourne in the lead—up to the australian open. they played against a group of firefighters to raise more money

for those affected by the bushfires, as australia experiences one of its worst wildfire seasons on record. 0ur sports correspondent andy swiss reports. announcer: the one, the only, the immortal, serena williams. cheering and applause. the biggest stars uniting for the biggest of causes. rally for relief — a chance for tennis‘s history makers to turn fundraisers. $100 to hit the giant letters? nice! no problem if you‘re roger federer. as for rafael nadal, well, he found a new doubles partner — deb, a firefighter who only on monday had been tackling the blazes near melbourne. it was a reminder behind the smiles of the reason why they were there. with two of the sport‘s great rivals leading the fundraising effort. talking with roger a couple of hours ago, we decided to give 250,000 australian dollars to the fires relief, together, so... cheering.

hopefully that keeps inspiring the people to support this terrible disaster that we are going through. earlier, the effect of the bushfires were still all too visible. with the air quality rated as unhealthy, qualifying matches in melbourne had to be delayed. they did eventually start, with thankfully no repeat of the previous day‘s drama when slovenia‘s dalila jakupovic had to retire with breathing problems. today, she said the conditions had been dangerous. we are used to pollution. like, we play in china, we play in more polluted countries, but, i mean, this smoke is something different and for sure we are not used to it. citizens and everyone who is advised to stay inside, and we didn‘t expect the tour would be playing yesterday. thunder and lightning. at last, though, some good news. rain, which forced qualifying to be suspended, but which should help the air quality. encouragement for organisers and players.

after raising more than £2 million, they will now be hoping the weather can offer some welcome relief. andy swiss, bbc news. and before we go tonight, a taste of what‘s to come in a special season which focuses on the future of the planet. i‘m in antarctica, satellite images show it‘s melting much more rapidly. the water is receding now, but then there are communities that have still not been reached. these soldiers in indonesia trying to clear a river blocked by plastic. walls of fire, 30, a0 kilometres wide. a crumbling norfolk cliff. this, though, could be the answer. a £20 million experiment. throughout 2020, across bbc news, there will be special coverage of issues affecting the climate and the planet. just a taste of what is to come on bbc news. now on bbc one, time for the news where you are. have a very good night.

good evening, i‘m asad ahmad. good evening, welcome to sportsday. i‘m also in hell would. coming up on the programme: a touch of class. manchester united march on to the fourth round of the fa cup. as preparations for the australian open continue to be hampered by smoke from bushfires, we hear the views of former champion kim clusters. of italy is not possible to play, then what‘s the point? italy is not possible to play, then what's the point? and draw for archer looks set to miss out on tomorrow‘s third test, as england plot to take the lead against south africa.

good evening, thanks forjoining us on sportsday. manchester united have edged their way into the fourth round of the fa cup, a brilliant goalfrom juan round of the fa cup, a brilliant goal from juan mata was the height of that 1—0 win against walls at old trafford, but their place in the next round may have come at a cost with a potential injury to a marcus rashford. patrick gary watch the action. a glance at old trafford stands, this was in the hottest tickets in town. but for wolves fans, it was among the most expensive. some paid £55 to get in, too much, according to their you to micromanager. somehow they ended up with... micromanager. somehow they ended up with. .. the teenager‘s micromanager. somehow they ended up with... the teenager‘s guilty look was telling, and in the va room, they spotted enough to take the goal

back. the next decisive wolves arm was there goalkeepers. how to deny danjames, it was there goalkeepers. how to deny dan james, it clearing was there goalkeepers. how to deny danjames, it clearing a united chance, creating a hole in the first game. but this was meandering until the wolves defence made it interesting. into the vacuum went juan mata, and what he lacks in velocity, he makes up for in sheer quality. those moments of belated i°y quality. those moments of belated joy gave way to another for concern for england. marcus rashford was soon off again, an injury that will be watched closely. wolves couldn‘t give them much else to look for, as the squad that has been playing sincejuly show the squad that has been playing since july show to the squad that has been playing sincejuly show to some of their mileage. united march on despite the detail. patrick gary, bbc news. mileage. united march on despite the detail. patrick gary, bbc newslj think detail. patrick gary, bbc news.” think you can see there‘s two teams there towards the end, they were tired. and to end an open game, which sometimes doesn‘t suit us, we wa nt to which sometimes doesn‘t suit us, we want to control the game. but you don‘t get an easier draw next
