you're watching bbc — i'm rich preston. our top stories. the world's biggest economies — china and the us — agree a joint approach to climate change at the cop26 climate summit. the united states and china have no shortage of differences but on climate, climate, cooperation is the only way to get this job done. migrants on the belarus border continue to suffer — as they try to enter poland. russia is accused of manipulating the situation for its own ends. the us teenager accused of shooting three people during a black lives matter

protest last year breaks down in tears on the stand. and more than 4 million people have shared a post on instagram in the belief that for each share, a tree would be planted. but was it all it claimed to be? we'll be hearing from the man behind the trend. welcome to our viewers on pbs in america and around the world. at the cop26 climate summit in glasgow, the world's two biggest producers of greenhouse gases — the us and china — have agreed to co—operate more closely on climate issues over the next decade. the two countries issued a joint statement pledging to help keep alive the hope of limiting global temperature rises this century to

1.5 degrees celsius. but they didn't say whether they'd back a draft international agreement, and instead called on all nations to reconvene next year with tougher carbon cutting targets. our science editor david shukman has the latest. can the world agree to slow down the release of the gases heating the planet? can it do what it takes to reduce the melting of the polar ice? and will this be enough to limit the rise of the sea? with the conference now entering its final days, delegates are trying to find common ground, and the uk, as host, has come up with a draft of a possible agreement. seven pages of text, welcomed as a first step by some but criticised by many. the words are almost meek and mild in many places, and the world is on fire. we've seen the australian wildfires, koalas being burnt alive. we need to make sure that we have got power and proactive commitments on the table.

any document like this is bound to be a compromise, so it calls for the first time for coal to be phased out — the dirtiest fossil fuel — but it doesn't give a date. it pushes for 1.5 celsius to be the limit of global warming, but currently, no one is on course to achieve that, and it urges countries to update their climate plans not in 2025, but far sooner, in fact next year, but there is no obligation. it needs to be really clear. there is no room for ambiguities and fudges. i see in this latest text, there's a lot of "urging" and "calling for", that kind of soft language, and it will need to be sharpened up, otherwise it will be very difficult to claim that this summit has succeeded. so the prime minister has stepped in, briefly, but, faced with an uphill struggle, he is now trying to manage expectations.

the cop26 summit here in glasgow is not going to fix it in one go. we're not going to arrest climate change right here, right now, that isjust impossible, and i think everybody has got to be realistic about that, but there is the possibility that we will come away from this with the first genuine road map for a solution to anthropogenic climate change. and that possibility was given a boost when china's top negotiator made a surprise announcement of a joint climate plan with the united states. the world's two biggest polluters agreed to reduce methane, a highly potent greenhouse gas, a positive signal of cooperation. the united states and china have no shortage of differences, but on climate — on climate — cooperation is the only way to get this job done.

we will soon see what that adds up to in this last phase of the talks, where china is among industrial giants worried about brakes we will soon see what that adds up to in this last phase of the talks, on its development. and others, like madagascar, victims of climate change, are desperate for this conference to get them help. kevin rudd, the former australian prime minister and now the president of the asia society, which has been working on global agreements on climate change, joins us now. what's your take on this agreement? thejoint statement by the chinese and the americans i think is a significant step forward. it's not a game—changer, as with the us china agreement back in 2014 in the lead—up to paris but it's a big step forward and for two or three reasons. the current state of geopolitics between china and the united states, whichjohn kerryjust

inferred is "goddamned awful" so the fact that you can extract this climate specific agreement between washington and beijing now is an important piece of momentum. the second thing is it re—establishes the us china climate working group which had been fluorescent in the wilderness for many years now. now been formally reared published and with an explicit focus on bilateral actions between the two countries in the 20 20s. not in the never—never. so i regard this as a significant development. positive but both countries in the past have made promises they have either not kept all gone back on. does the world have cause to believe this would be any different? figs have cause to believe this would be any different? as far as the united _ would be any different? as far as the united states _ would be any different? as far as the united states is - as the united states is concerned, we have a disaster of the trump administration where the united states walked away from all of its national and international commitments on climate change. on that we

would be subject to the electoral process in 2024 over which the rest of us have no control. god forbid we end up with another climate denying president in the white house but under the barden administration there is clear commitment to act domestically and internationally, hence why kerry was able to do what he did today. for beijing, the arc of history bends slowly towards climate action. i remember copenhagen where china was actively in the business of blocking any form of international agreement. paris, they step up to new forms of agreement and now, what you see with this re— energisation of their bilateral collaboration with washington, looking at sectoral specific initiatives, evenin sectoral specific initiatives, even in methane, forestation and regulatory standards which i assume refers to electric vehicles as well, this is a positive step forward so not perfect but i would certainly give it more than the six out of ten on the richter scale of

achievements.— achievements. president xi didn't go — achievements. president xi didn't go to _ achievements. president xi didn't go to cop, _ achievements. president xi didn't go to cop, china - achievements. president xi l didn't go to cop, china didn't sign up to the pledge to shift away from coal. it's going carbon neutral by 2060, a decade behind most other countries. it didn't sign up to the big methane agreement early on in the summit. is it doing enough at home to limited zone emissions? the rest of us would say internationally know because china is now the world's largest emitter and by mid century, cumulatively will have more greenhouse gases in the atmosphere coming out of china and the united states, when you take the historical emissions into account but the bottom line is, the trendline in terms of chinese action is like this, i would prefer it was like that, but it is like this, and that is better than we have been before. 0n methane in particular, what i find significant is that china, having excluded its name from the international agreement, which was put forward at cop

recently, nonetheless explicitly identifies methane is an area which will now work on with the united states in the headset frankly full marks to john kerry and the headset frankly full marks tojohn kerry and his chinese counterpart to pull this out of the ashes and remember, we are probably less than a week away from a bilateral summit between xijinping and president biden. hopefully that will further stabilise the us chain of relationship and create more political space for active approaches to this climate change agenda in both capitals for the 12 months ahead. great, we will leave _ for the 12 months ahead. great, we will leave it _ for the 12 months ahead. great, we will leave it there. _ for the 12 months ahead. great, we will leave it there. kevin - we will leave it there. kevin rudd, former prime minister of australia. thank you for being with us. let's get some of the day's other news. the us plane maker, boeing, has admitted liablity for a crash two years ago in ethiopia of one of its seven—three—seven max aircrafts. -- 737. all 157 people on board were killed. in a submission to a court in chicago, boeing acknowledged

that the plane was unsafe. the firm said it was committed to ensuring that the families of those who died were compensated. the un security council has expressed deep concern at the latest violence in myanmar between the ruling military and opposition groups. in a rare statement agreed by all its members, the security council called for an immediate end to fighting and urged the military authorities to exercise utmost restraint. a french court has sentenced a man who killed an 85—year—old jewish woman to life in prison. yacine mihoub was convicted of murdering mireille knoll in her paris apartment three years ago during a botched robbery that was motivated by anti—semitism. she was stabbed 11 times and her body set alight. the german chancellor angela merkel has told president putin that russia must stop what she called the �*inhumane' exploitation of the migrant crisis on the border between poland and belarus. thousands of people have massed in the area wanting to cross

into poland and enter the european union. poland's prime minister has accused belarus of �*state terrorism' in its handling of the crisis. 0ur correspondent nick beake sent this report. for those who'd hoped to find a new life safe in the european union, there is a grim realisation that this could now be home — trapped between belarus and poland. the bbc was sent these pictures as journalists and, crucially, aid agencies are being kept away. it is very, very bad. we managed to contact ilias, who was a scientist in iraq. he wants eu member poland to let them through. my message is, i want open the border to poland. why should poland open the border to you? one day, two day, three day, after, have died. you fear that people will die?

yes. poland has been accused of pushing back migrants illegally. but it wants to highlight this — belarussian troops appearing to force migrants along the border, the polish accusing belarus of terrorism, masterminded by russia. and tonight, angela merkel appealed directly to moscow. translation: you are all following these - disturbing images. i had russian president vladimir putin on the phone today and i asked him to take action with president lukashenko because people are being used here. but, russia has hit back, claiming the eu is provoking belarus. moscow released this footage which, it said, showed two bombers being sent to patrol its ally�*s airspace in a show of solidarity and strength, as international tensions rise from this border chaos.

this huge forest, called bialowieza, is one of europe's oldest woodlands, but it's now the epicentre of the continent�*s newest migrant crisis. thousands have been trying to make their way from belarus, through these trees, to here in poland. and many more are set to follow, determined to take their chances in this wilderness, if it means reaching eu soil. because, in belarus's capital, minsk, more families were preparing to head to the border after being welcomed by president lukashenko's regime, undeterred by the spiralling misery tonight in the makeshift camps that soon awaits them. nick beake, bbc news, on the poland—belarus border. stay with us on bbc news, still to come: $1 million better off — we meet the teacher who's just won a unesco—backed, global prize.

the bombastic establishment outsider donald trump has defied the pollsters to take the keys to the oval office. i feel great about the election results. i voted for him because i genuinely believe that he cares about the country. it's keeping the candidate's name always in the public. eye that counts. success or failure depends not only on public display - but on the local campaign l headquarters and the heavy routine work of their women volunteers. i berliners from both east and west linked hands and danced around their liberated territory. and with nobody to stop them, it wasn't long before the first attempts were made to destroy the structure itself. yasser arafat, who dominated the palestinian cause for so long, has died. palestinian authority has declared a state of mourning. after 17 years of discussion, the result was greeted with an outburst ofjoy, leaving ministers who long felt only grudgingly accepted among the ranks of clergy suddenly felt welcome.

this is bbc world news. the latest headlines: a surprise move as the world's biggest economies, china and the us, agree to a joint approach to climate change. migrants on the belarus border continue to suffer as they try to enter poland. russia is accused of manipulating the situation for its own ends. a rust film crew member who witnessed the fatal on—set shooting of a cinematographer has filed a negligence suit against actor alec baldwin and the producers. in the lawsuit, chief lighting technician serge svetnoy, accused the producers of rust of �*negligent acts and ommissions�*, stating �*there was no reason for a live

bullet to be on set�*. halyna hutchins was shot and killed by baldwin during rehearsals for the western in new mexico. director, joel souza was injured in the incident. a us teenager charged with shooting three people during civil unrest on the streets of wisconsin last year has taken the stand in his own defence. kyle rittenhouse broke down in tears, forcing a brief recess, as he described how he was cornered by several men and acted in self—defence. the teen has pleaded not guilty to all charges against him. i was cornered from in front of me with mr zelenskiy and there were... there were three people right there.

friendly, friendly". he says one of the men threatened him after he hit him in the head with a skateboard and another pointed a gun at his face. as we havejust seen, he broke down in tears while providing his testimony. the trial had to be put on hold for a short while. and then they came back and he was cross—examined by the prosecutor. and that led to the prosecutor. and that led to the judge actually criticising the judge actually criticising the prosecution for the line of questioning and he said the prosecutor had doubted the sincerity of the tears that everyone had just witnessed while he was on the stand. and he also referred to a statement he also referred to a statement he had made in social media that he wanted to be famous, this is kyle rittenhouse, and also reference to a photograph that prosecutors they showed him standing next to some extreme right—wing protagonist. the judge extreme right—wing protagonist. thejudge said extreme right—wing protagonist. the judge said that that scope

of questioning was beyond the questioning that had been agreed and was allowed for that stage of the trial.— stage of the trial. peter, when does the trial _ stage of the trial. peter, when does the trial go _ stage of the trial. peter, when does the trial go from - stage of the trial. peter, when does the trial go from here, i does the trial go from here, there had been some suggestions that there might be claims of a mistrial, which means it goes no further for mistrial, which means it goes no furtherfor mr mistrial, which means it goes no further for mr rittenhouse. yes. after that confrontation, if you like, between the judge and the prosecution it was the defence that made a call for a mistrial and thejudge defence that made a call for a mistrial and the judge has yet to rule on that. so we don�*t know where that is going to go at the moment. it seems for now the trial will continue. kyle rittenhouse testifying on his own behalf. and that is a very unusual move for a defendant in a very serious case like this, it is seen by lawyers as being quite risky in legal terms, you don�*t know what is coming from the cross examination by the lawyer on the other side. but he has testified on his own behalf. he is the third defence witness. and, for now, the trial continues.— trial continues. peter, we believe — trial continues. peter, we believe it _ trial continues. peter, we believe it there. - trial continues. peter, we believe it there. thank i trial continues. peter, we l

pushing through northern ireland, parts of wales, northwest england on toward self with scotland today is the day goes on with the fresh wind in the west. these are average speeds, some gusts of around 40 miles an hour developing on the western coasts by the end of the day. but with that, the milder air is coming back into belfast at 14 degrees. it will start to creep northwards across scotland once again with this area of rain. and as we go on through thursday night, there will be a few spells of rain running into northern ireland and scotland, northern england, wales and a few patches of rain just starting to push a little further east across england as a going to friday morning. it is a mild night, mild start to friday. let�*s take a look at that area of low pressure. looks to be working across scotland during friday but of course the weather from around it will be impacting all of the uk. doesn�*t mean to say we�*re all get to see a huge amount of rain. the further south you out to just be a few splashes here and there. closer to that low pressure system through northern ireland but especially central southern parts of scotland and england the chance of seeing the heavier dampers on friday for the early rain on the far north of mainland scotland the rest of the day looks dry. it�*s a blustery day across the uk again,

it�*s another mild one of us up into the weekend this area of low pressure will move away quite quickly allowing high pressure to build in behind but that settles the weather down again. it will become mainly dry over the weekend, there will be a lot of cloud around, sunshine at a premium regardless though, we have a mild weekend on the way.
