welcome to our viewers on pbs in america and around the globe. we begin in america where the us house of representatives has approved president biden�*s $1 trillion infrastructure bill, a key part of his programme to rebuild the united states following the coronavirus pandemic. it's the final stage in its legislative progress before it's signed into law. a vote on a second bill, on social policy and climate change, has been delayed. our north america correspondent, david willis, joins us from los angeles. bring us up to speed. a major bring us up to speed. a ma'or victory for d bring us up to speed. a ma'or victory for president i bring us up to speed. a major victory for president biden. it| victory for president biden. it was a landmark centrepiece of his legislative agenda and it looked at one stage as though it threatened to get bogged down in interparty wrangling which has gone on now four weeks if not months. the senate actually signed off on this trillion dollar plus infrastructure bill in august and has taken all this time for the house of representatives to agree on it. at one point there were progressives who were looking to tie the passage of this particular legislation to a separate bill of $1.8 trillion social spending and climate control bill which was close to the hearts of many of them. the house speaker, nancy pelosi, decided to take this to the house floor for a vote tonight. she has always said in the past that she will only do that sort of thing she is confident of winning a vote and at one point that looked a bit unlikely because some of the liberals, disgruntled liberals, were actually threatening to withhold their votes of support for the infrastructure bill because of the declining fate of the social spending legislation but in the end with the help of some republicans, they pushed it over the line tonight. president biden will be delighted, he was due to go to delaware, to his home state. he held off doing so to put his political might behind the effort to get the legislation over the finish line tonight and he will be well pleased as and he will be well pleased as a result. �* , , a result. i'm sure he will be breathing — a result. i'm sure he will be breathing a _ a result. i'm sure he will be breathing a sigh _ a result. i'm sure he will be breathing a sigh of - a result. i'm sure he will be breathing a sigh of relief. . a result. i'm sure he will be l breathing a sigh of relief. you know what the $1 trillion will be spent on? know what the $1 trillion will be spent on?— be spent on? yes, roads, bridges — be spent on? yes, roads, bridges and _ be spent on? yes, roads, bridges and ports. - be spent on? yes, roads, l bridges and ports. basically overhauling this country's creaking infrastructure. broadband internet access and our people, overhaul —— overhaul of the nation's roads, railways and so on. this is a massive measure that the president says will create. it will boost the economy considerably and he needs that because the results last week from those governor elections in both virginia and newjersey showed that a democratic popularity has plummeted in the yearin popularity has plummeted in the year in which mr biden has been in office. largely it is thought because of this legislative inertia that we've seen. no longer now the democrats have something to share. the swedish climate activist greta thunberg has accused world leaders of deliberately postponing much needed drastic action against global warming, and says they are fighting instead to keep the status quo. addressing thousands of young people at a rally in glasgow, she called the cop26 climate summit — a �*failure' — and little more than a celebration of �*business as usual�*. the bbc�*s sarah smith sent this report from glasgow. a rare opportunity for protesters to loudly deliver a message almost within earshot of the global decision makers gathered in glasgow. greta thunberg, who inspired the fridays for future movement, says those leaders have so far failed to deliver. young kids, inspired by greta, have drawn their own pictures of her. i know that she put out a sign and then everybody else started following her, just like this. how do you talk to children this age about climate change without scaring them too much? i don't have to — they themselves are aware. they know about plastic, about pollution, about air pollution. what do we need? climate justice! as the government announced measures to put climate at the heart of education, kids — mostly with their parents�* permission — were skipping school to take part in this youth protest. your sign says "now means now, not later". why did you write that? i wrote that because they're saying "we need to do this now. "we need to get this now. "we're going to sort this now." but they're not sorting it. they're just going to make promises they can't keep. do you think that's what the world leaders at cop are doing? making promises that you don't think they're going to keep? yes, this has happened a lot of times before. people say they're going to do things and they don't make enough change to actually have an impact. i'm really hoping that the folk in cop, sitting there, drinking theirtea, are listening, and they're listening to what we have to say and trying to make a change. do you not think they're trying to achieve the same thing as you, to lower carbon emissions and trying to save the planet? yeah... i don't know. i think they are trying, but we're trying harder. so far at this cop, there have already been commitments to reverse deforestation, cut methane emissions and promise more money than ever before to tackle climate change. greta thunberg, who's at the front, doesn't seem very impressed with the progress of cop so far. what do you think? i think it's fair enough. you know, it's cop26. i'm 26 years old, it's been 26 years, no progress has been made and our carbon emission keeps increasing. we need action. on stage, ms thunberg dismissed cop26 as a pr exercise. this is no longer a climate conference. this is now a global north greenwash festival. a two—week—long celebration of business as usual and blah, blah, blah. they cannot ignore the scientific consensus. and, above all, they cannot ignore us, the people — including their own children. tomorrow, even larger crowds are expected, hoping to keep up the pressure before the final week of climate negotiations. sarah smith, bbc news, glasgow. and the first demonstrations have begun in australia, in what's being billed as a global day of action for climate justice. sydney, where it'sjust gone 3pm, is one of nearly 200 cities where protests are being held. the day is aimed at encouraging political leaders to make stronger commitments to limit climate change. organisers say the people that have done least to cause the climate crisis are bearing the brunt of its effects. in other news, the brazilian country singer, marilia mendonca, has been killed in a plane crash on her way to perform in a concert in the southeast of the country. four other people — her uncle, her producer and two crew members — also died when the small private plane went down in a mountainous area. ms mendonca, who was 26, was a feminist icon in the country and won a latin american grammy in 2019. the bbc�*s courtney bembridge gave me more details. well, the plane crashed not far from where the concert was due to take place on friday evening. as you said, it was a mountainous area beneath a waterfall, and television images show the damaged aircraft there as rescue crews went in, but unfortunately, all five people on board were killed in that crash. an investigation is now under way into exactly what happened. there's been some reports that the plane may have hit powerlines, electricity lines, in that area — as i said, it was not far from it was due to land — so that investigation is ongoing. but marilia mendonca was one of brazil's most popular contemporary singers and so at the moment, the country is in mourning. she won a latin grammy, as you said, in 2019 and last year, she was the most listened to artist on spotify in brazil, the streaming service. so one commentator described her as a kind of country singing adele. she had shows of a beyonce scale in terms of the crowds that were there. that commentator also said that her death will hit brazil in the same way that amy winehouse hit the uk, so it gives you an idea ofjust how big a personality she was in that region and in brazil. she started her careerjust as a teenager there, had a big hit in 2016 and her popularity has soared since then. she was known as the queen of suffering because she sang about breakups and but she also focused on female empowerment and that won her legions of fans — she had a huge social media following, 39 million followers on instagram — and not long before the plane crash, she actually posted on twitter a video of her boarding the plane, asking her fans for tips of what she should eat in that local area where she was going to perform so herfans have paid tribute to her and the whole country is in mourning. what are we seeing in the way of tributes? well, brazil's presidentjair bolsonaro has tweeted, and we can bring that up — it is in portuguese — but he said "the whole country receives in shock the news of the death. "she was one of the greatest artists of her generation. "with her unique voice, charisma and music she won the affection and admiration of all us." so that was shortly after the announcement. also, herfriend the brazilian footballer neymar has also released a tribute and he tweeted a very simple message, "i refuse to believe, i refuse" with a crying emoji there. so tributes are starting to come in. very sadly, she leaves behind a two—year—old son and millions of fans and the country is coming to grips with the fact she was only 26 years old, and killed very suddenly when she was at the peak of her career and increasing in popularity. let's get some of the day's other news. it's emerged that a russian diplomat was found dead in october outside the country's embassy in berlin. his body has been returned to russia. foreign ministry officials declined to be drawn on a german press report that the diplomat was suspected of being an undercover agent for russia's fsb security service. der spiegel said the man had apparently fallen from an upper floor. it quoted the russian embassy as saying the incident was a tragic accident. a memorial service has been held at washington's national cathedral for the late colin powell, who died last month. president biden was among those attending. powell was the first black us secretary of state, a retired army general and a former national security adviser. he died at the age of 84 due to complications from covid—19. and 11 us states are suing the biden administration over its plans to get workers vaccinated or regularly tested for coronavirus. the missouri attorney general�*s office says it's seeking a judicial review and that the federal agency in charge of the plan doesn't have the authority to issue it. the biden administration has said all companies with 100 staff or more will have to comply with the rule from january or risk big fines. staying in the us, and the trial of three men accused of murdering a black man while he was outjogging has begun in the us state of georgia. the death in february last year of 25—year—old ahmaud arbery sparked protests across the us. further controversy has followed after a nearly all—white jury was selected for the trial, in which the defendants have pleaded not guilty. our north america correspondent aleem maqbool is in brunswick, georgia, and sent this report. as the trial opened, video of ahmaud arbery�*s final moments was played. all too much for his mother, who let out a cry. sitting in front of her in the foreground here, the man who pulled the trigger. this was the video they were watching — three armed white men had pursued ahmaud, saying he resembled a burglary suspect. they cornered him and shot and killed him. ahmaud arbery, an avid runner, had been jogging through this area just a short distance from his own home when the men decided tojump into their trucks and give chase. their own statements show one of the men involved in the killing of this 25—year—old used a racial slur as he lay dying. well, sadly, murals of unarmed black men who have been shot and killed are now dotted in towns and cities right across this country. but in ahmaud arbery�*s case, he didn't die at the hands of the police, but at the hands of people who believed they could act as an extension of law enforcement and do what they like — and that, after his death, appears to be precisely how the police treated them. policewoman: that's fine, that's fine. there's body—cam footage that's too distressing to show, where we see ahmaud arbery writhing on the ground, dying, not being given attention. throughout the encounter, police provide comfort to the men who killed him. do what you need to do, man. that's. .. i — i can only imagine. they certainly don't appear to be treated as murder suspects. you're not putting me in cuffs, are you? no, no, no. why would you be in cuffs? well... in fact, it was only ten weeks later, after protests when the video of the killing taken by one of the men went viral, that travis mcmichael and his father greg and roddie bryan were even arrested. they were eventually charged and now go to trial. you can intentionally and deliberately kill another person in self—defence and not have committed murder. you would be not guilty. and it's still self—defence if they chased him? that's because they were attempting to execute a citizen's arrest. ahmaud's case has already led to the scrapping of a civil war—era citizen's arrest law in georgia. before the trial started, his mother told me she hoped somehow, good would come out of this tragedy. i hope that in losing ahmaud, that people that look like ahmaud would be able tojog, they'd be able to run, they'd be able to do whatever and be free and not to be worried about being chased with guns and killed. for the trial — taking place in a city that's majority black — there will be only one african—americanjuror. and here, it appears easier to overturn laws than to change the attitudes that undoubtedly contributed to ahmaud's death. aleem maqbool, bbc news, brunswick, georgia. this is bbc news. our main story this hour: a breakthrough for biden: the us house of representatives approves the president's $1 trillion infrastructure programme. swedish activist greta thunberg has branded the cop26 climate conference a failure, describing it as a "global greenwashing festival". staying with climate, conferences like cop26 don't talk enough about threats to the species that make up the natural world, according to the director—general of wwf international. marco lambertini told our environment reporter navin khadka that that more attention should be paid to animals in all ecosystems. it is true that when we talk about nature, we seldom go down to the level of species and individuals that are making up the natural world of today and by the way, species and individuals, which are declining sharply, in the last 50 years, we have seen two—thirds decline of wildlife population globally. less than 50 years, the blink of an eye compared to species that have been around on the planet for millions of species, and suddenly because of our intervention, their population has plummeted. 1 million species are on the brink of extinction. all these are tragic figures that on one hand affect the productivity, the functionality, the resilience of the natural world, it provides so many services to us, so that is a utilitarian perspective, but also on the other hand, these creatures have the right to exist and we have the duty to coexist with life on earth because this is not our planet, this is the planet that we are passengers on, we are not the captains. so you agree that wildlife, flora and fauna are by and large ignored in these meetings? until recently, nature and wildlife conservation was based on a moral duty to coexist, but the new narrative that is emerging, which is actually equally powerful, it's notjust the moral duty but also it is a fundamental necessity, because our economy, our society, health depends on nature. but it doesn't mean that looking at nature as a service and all the goods and services it provides to us should alienate and make us ignore the rights and value of nature and the right of all these creatures to exist and share the planet with us. how badly has wildlife been impacted because of climate change, and how has that increased the challenges for you in nature conservation? climate change has been rising in the number of threats to wildlife steadily over the last few decades. right now, it's considered to be the third biggest threat. the first threat is habitat conversion, so particularly forfood production and feed for farmed animals around the world. that the number one threat. but climate change is already the third, and it is affecting species in mountain levels because they are changing the climate, they cannot move up any more, it is affecting through droughts, wildlife everywhere in the world, it is affecting wildlife through wildfires, forest fires around the world as well. high—temperature heat waves are becoming an issue as well, particularly in the ocean, half of the great barrier reef has been killed by underwater heatwaves. we have the of fruit bats in australia that have died of heatstroke, things that have never happened before, and unfortunately now are beginning to happen. the row over racism at yorkshire, one of english cricket's most famous clubs, has intensified with the resignation of its chairman. the worst crisis in the club's history has been sparked by a year—long investigation that found former player azeem rafiq had been the victim of racial harrassment and bullying, but no disciplinary action was taken. former england captain michael vaughan was one of those named in the investigation, accused of making a racist comment to a group of asian players — something he strongly denies. here's our sports editor dan roan. the racism that cricketer azeem rafiq suffered at yorkshire has plunged the county into an unprecedented crisis. today, as the fallout continued, the chairman bowed to intense pressure to step down and, just hours after announcing his resignation, roger hutton told me that the club had let their former player down. i am sorry that he did not have his allegations investigated in 2018. i am sorry that it has taken so long. i am sorry that ultimately, the club has not shown the right contrition. i have not personally met anyone that i would consider a racist at yorkshire county cricket club. what i have seen is a culture that is locked in the past. amid more resignations at headingley today, hutton blamed senior management who, he said, resisted change after a report found rafiq had suffered racial harassment. there was a failure by many within the club to accept its findings or understand them or recognise them and since then that has been incredibly frustrating. the ecb has banned headingley from hosting england matches, but hutton said the governing body should have done more to support the investigation. i heard a statement last night from the ecb that they repeatedly offered to help me and yorkshire county cricket club through this investigation. that couldn't be further from the truth. yorkshire batsman gary ballance had admitted repeatedly using a racial slur towards rafiq about his pakistani heritage, but a panel regarded it as "friendly banter" and no action has been taken against any member of staff, sparking outrage. do you accept that conclusion that they reached? that it was friendly banter? is that how you would deem that expression, that phrase, towards a colleague? no, if you are using that language, it is completely unacceptable... so why was there no action taken? because you have not seen the context of the whole of the report — and the club had legal advice that actually, that was not something that you could take disciplinary action in relation to. is ballance the only current member of staff that there has been an allegation upheld against? no. former england captain michael vaughan, meanwhile, has become the second player to reveal he is named in the report; rafiq alleging that he had made a racist comment towards a group of asian players in 2009. vaughan denies the claim but today, one of those players said he had heard the alleged comment. a prominent pundit, tonight he was stood down from his radio show next week. in a statement, a bbc spokesman said: this all comes at a time when cricket is desperate to engage with the south asian community and make the sport more diverse, and some fear that this damaging episode may send the game backwards. it is more about trying to get systemic change in a club like yorkshire, which, change has proven to be very difficult and the club, i think, has failed to evolve quick enough in the way that society is changing in our attitudes towards race and racism. this has been a devastating week for the most successful club in county cricket, but the ramifications of this remarkable saga now extend well beyond headingley. scientists in chile have unveiled dozens of fossils that they've found in the country's atacama desert. tim allman has more. some call this the desert graveyard — an arid, desolate place. but dig down deep beneath the sand and the topsoil, and it is somewhere rich in hidden knowledge. fossils and bones, an insight into life on this planet from another age. translation: we found different types of vertebrates. _ without a doubt one of the most striking is a wonderfully large fish, a shark. it is the megalodon. it is famous because of the hollywood movie the meg and this is the place where the largest number of their teeth have been found. and this is what that wonderfully large fish might have looked like. it is believed the megalodon lived somewhere between 23 million and 3.6 million years ago. they could grow up to 20m in length, a fierce and terrifying predator. quite the discovery, but no surprise to anyone around here. translation: atacama is nature's laboratory. i to understand the origins of the universe, and also how vertebrates have evolved, as well as the lineage of marine animals over the last 8 million years. after being neglected for decades, around 2,500 hectares of this land are now preserved as a protected site. a place for discovery, and the uncovering of secrets. tim allman, bbc news. you can reach me on twitter — i'm @richpreston. from the ember team, goodbye now. —— me and the team. hello there. after what was, at times, quite a chilly week of weather the weekend is getting off to a relatively mild but relatively cloudy start. you can see that cloud spilling in from the west on our earlier satellite picture. with that, though this feed of westerly winds and mild air certainly making its presence felt through the day ahead. so we can sum saturday's weather up like this, it will be mild, it will be turning windy though. increasingly windy, particularly in the north of the uk and for some there will be some outbreaks of rain. courtesy of this area of low pressure and this frontal system pushing in from the north—west. some quite heavy bursts of rain across the western side of scotland, that rain more generally pushing south eastwards across scotland and northern ireland through the morning. that rain getting down into parts of north—west england and north wales during the afternoon. ahead of that, eastern and southern counties of england will stay predominantly dry, but rather cloudy. limited sunny spells. the skies will brighten in the north—west of the uk, but with some showers and some windy weather later in the afternoon. top temperatures 11 to 1a degrees. it will be mild out there. during saturday night we see this band of cloud and patchy rain pushing across the south. more pushing into the north—west where it'll be turning very windy indeed. exposed spots in northern scotland seeing gusts of wind in excess of 60, perhaps more than 70 mph. that could cause some disruption. a relatively mild night once again — eight, nine, ten or 11 degrees to take us into sunday morning. as we start sunday, low pressure passing to the north of the uk, all the white lines, the isobars squeezing together. indicative of a windy start to the day, especially in northern scotland, we will keep some showers going through the day. most other areas will be dry and there is a decent chance of seeing some spells of sunshine through sunday afternoon. temperatures may be down a little, but still quite mild. 10—13 degrees. and then as we head through the coming week, high pressure will try to hold on towards the south of the uk. whereas we will see frontal systems from time to time pushing across northern and western areas. so what that means that the driest of the weather will be found towards the south and east, closest to that area of high pressure. more chance of rain at times towards the north—west but for all of us it is going to remain mild. this is bbc news, this is bbc news, the headlines: the headlines: the us house
