this is bbc news with the latest headlines for viewers in the uk and around the world. climate activist greta thunberg leads thousands of young protestors through the streets of glasgow to demand world leaders take stronger action at the summit on climate change. we are tired of their blah blah blah. our leaders are not leading! this is what leadership looks like! we report from a village in northern alaska where climate change is forcing people from their homes. the un security council calls for an end to the fighting in ethiopia, asking both sides to refrain from the use of hate speech. prosecutors in georgia allege that ahmaud arbery, an unarmed black man killed last year, came �*under attack�* from three white men charged with his murder. and resignations at yorkshire county cricket over the racism row which has

engulfed the club. the swedish climate activist greta thunberg has accused world leaders of deliberately postponing much needed drastic action against global warming and said they were 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 that a celebration of �*business as usual�*. here's our scotland editor sarah smith. 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. 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 are 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, drinking their tea, - are listening, and they're listening to what we sayl and trying to make a change. do not think they're trying to achieve the same thing as you, to lower carbon emissions and save the planet? yeah... i don't know. i think they are trying, i but we're trying harder. so far at this cop, there have 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 and 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 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. chanting: no more pollution, we need a revolution! - some locations have to grapple with the consequences of the changing climate every day. people living in a village on an island in northern alaska face being forced out of their homes by rising sea levels. alaska is home to rapidly retreating glaciers where the rate of melting is among the fastest on the planet. our climate editor justin rowlatt has been to see what's happening. we are here in alaska because this place, in a way, is the kind of canary in the mine for the climate issue. because temperatures

are so close to freezing, if you raise them only a little bit you get really big changes. so ice that used to remain frozen, and snow that used to fall and then stay until the spring or the summer is now melting or melting earlier. and that is driving profound changes here in alaska as i have been discovering. the top of our world is changing. warming twice as fast as the rest of the planet. and it is destroying communities. yeah, my house used to be about 20 feet out where you see the water breaks. this island is on the front line of climate change. as temperatures rise, less sea ice forms, exposing the coast. it is getting later and later every year, for this ocean to freeze up. it is tough. but you have got to keep going. as the climate changes, the animals and fish that people here used to live on are getting harder to find. right now we are supposed to be

fishing in the lagoon and up - the river, now we have got a wait until like, _ december, january, . to start going up there. parts of the main road have washed away and now the airstrip that is the community's lifeline to the outside world is threatened. if it gets to the runway, then we can't use it any more. we use the runway for medevacs, we use the runway for getting all our food flown in. the plan is to move the entire town onto the mainland. it will cost an estimated $180,000,000, but, says dennis, they have got no choice. the climate is changing so fast, and the storms are getting more violent, you know, ice is not forming and the water is warming. i mean, i would say within the next five or ten years this will all be covered. easy. just that one or 2 degrees

makes a big difference. and alaska isn'tjust struggling to cope with its new climate reality on the coast. a century ago, the glacier came all the way down here, the entire valley was frozen and as recently as the 1980s, they built this visitor centre, because you could still see the glacier in the valley. since then, it has completely retreated around the corner and you cannot see it at all. we are almost around - the corner, you should be able to see the glacier. these days, if you want to see the ice, it is now a tough hike up and over a high pass. this is all that remains of the once mighty glacier and mountain glaciers are not just melting here in alaska, they are melting all over the world, potentially affecting millions of people who depend on ice for their water supply. if we did not have glaciers, -

we are no longer going to have drinking water for our cities. we might not have any hydrol power potential and especially for agricultural needs, . we would have water only maybe during the winter months and not during l the summer months. for the dry periods, - there would be no water. back here, alfred is struggling to come to terms with the idea that his home will soon be gone. this place means a lot to me, because it has got a lot of heritage, a lot of good people, while we are here we just have to keep our traditions going. try to keep going strong. it isn't easy to let go of the place where you have spent your entire life, but if greenhouse gas emissions are not cut rapidly, it is something many millions more people are likely to have to face. so, really profound changes here in alaska. and it points to a much bigger picture, and when i say much bigger, i mean really big! because what climate experts are saying is that the rising

temperatures we are seeing could be taking the earth out of the cycle of ice ages that we have been in for the last couple of million years. pushing us into a new, and uncertain, climate reality. 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. mendonca — who was 26 — was a feminist icon of the brazilian country music style known as �*sertanejo'. she won a latin american grammy in 2019 — and in 2020 was the most listened to artist in brazil on spotify. the cause of the crash is not yet known. the un security council has expressed deep concern about the intensifying

conflict in ethiopia. it came as nine rebel groups formed a new alliance, aimed at removing the current government of prime minister abiy ahmed. the year—long was has left over 400 thousand people facing famine—like conditions. our africa correspondent, catherine byaru hanga has this report. in washington, dc a coalition of armed groups and political movements announce they want to remove ethiopians government. many of them come from historically marginalised ethnic groups. now with a stronger to great peoples fund which has been fighting federal forces for a year. the next step would be to organise ourselves and totally dismantle the existing government either by force or by negotiation, whatever they wish. and then transitional government as soon as possible. but back home the governments they opposed led by the prime

minister is defiant. and dismissed the alliance is a publicity stunt. pushing back his claims as undemocratic. it's quite worrisome that many allegations being lodged against the government being done so in a matter to discredit a tablet two democratically elected majority support. this majority support was demonstrated in a landslide victory following the 2021 elections. ethiopians government continues to be tested. it's lost significant towns and cities to tigre and rebel forces who are advancing towards the cup to net capital. they came to hold territory three km north on one of africa's biggest cities. on tuesday the government declared a state of emergency and urge citizens to arm themselves against its opponents. but there are fears the tough measures are being used to detain ethic to grands because of claims they support the rebels.

police took my brother with his friends while they were having dinner in a restaurant. all of them were from tigray. they usually ask you to show id and it indicates that you are from tigray they immediately take you to prison. it's hard to speak at any place in the city because we don't feel safe. the government says arrests were only made after obtaining evidence of illegal activities. ethiopians year long war has created one of the world's worst humanitarian crises. over 7 million people need emergency aid and 400,000 are on the brink of salmon. yet the warring sides are not listening to international calls to end the war. a reminder of the headlines. swedish activist greta thunberg has branded the cop26 climate conference

a "failure", describing it as a global greenwashing festival. the ethiopian government dismisses the threat posed by a new alliance of nine rebel factions — despite their advance towards the capital. 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. 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. 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...| 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. 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—i9. ii us states are suing the biden administration over its plans to get workers vaccinated or regularly tested for coronavirus. the missouri attorney generals 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. let's look more closely at one aspect of climate change. researchers say the carbon

footprint of the world's richest people threatens the goal of keeping global warming under one point five degrees celsius — despite commitments made in the run up to the cop26 conference. the carbon footprint of the world's richest 1% is on track to be 30 times higher than what's needed to limit global warming to i.5c. but emissions of the poorest 50% will continue to be below climate goals. noah diffenbaugh, climate scientist at stanford university, told us we all need to take responsibility. well, you know, we have known for quite a while now that the driver of greenhouse gas emissions and global warming is energy consumption. energy consumption is fundamentalfor human well—being, we also know that it's very unequal across the world band, you know, the richest people and the richest societies, the richest countries not only consume a disproportionate amount of energy, but are responsible for a vastly disproportionate amount of the greenhouse gas emissions. i'm here in the united states, the us is responsible for about a quarter

of the historical greenhouse gas emissions. the eu and uk together responsible for more than 20% of the historical emissions. so this has been well understood. what's clear is global warming is happening, it's going to continue the more emissions we have than the more global warming and climate change that we will get. in the world needs to simultaneously supply more energy than it does, and much more equitably for the needs of all of humanity, and in order to meet the un paris climate goals. you know, the fundamental physics of the planet earth dictate that we will have to reach net zero emissions. why should someone in beijing change the way they lived when they might look and see how people in the west live and think, you have had your industrial revolution, you got rich, are you telling us not to get rich? yet, so this has been a primary challenge for the international payment negotiations

for decades now. on a per capita basis, the us is a very, very high emitter compared to other major countries including china, including the eu, including india. so the real challenge is, again, how do we supply the world public needs while also meeting the un climate goals. the good news is that we do have options, would you have technologies now that are, that provide the opportunity to scale and critically to leapfrog. you know, if the whole world takes the development pathway that led to my well—being as an american, we are going to have a lot of global warming. the good news is that even though we are a fossil fuel dependent global energy system now, it is possible for it not to be that way. and we are seeing goals across major emitting countries. you know, the biting administration has a goal

of reaching net zero by 2050, the eu by 2050, china by 2060. goals are there, the question is really, is the world able to scale these solutions at a much more rapid rate than what is happening now? 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 and in his first interview 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 in the club to accept its findings or understand them or recognise them and since then that has been incredibly frustrating. the england and wales cricket board punished yorkshire by banning headingley

from hosting england matches, but hutton said it 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 do this investigation. that could not 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? if you are using that language, it is completely unacceptable. so why was there not 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. in a statement, the bbc said... this all comes at a time when cricket authorities are trying to 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 and 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. a reminder of our top story... the swedish activist greta thunberg has dismissed the climate cop26 summit as a failure, accusing world leaders of trying to maintain the status quo with distant non—binding pledges. addressing thousands of young people in the scottish city of glasgow, she said politicians were actively creating loopholes and profitting from the destruction created by climate change while neglecting urgent drastic cuts to co2 emissions.

much more on our website. 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 wendy 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 northwest. quite heavy bursts of rain across the west side of scotland, that ran more generally pushing south across scotland and northern ireland through the morning. that rain getting down into parts of northwest 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 northwest 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 with see this band of cloud and patchy rain pushing across the south. more pushing into the northwest where it'll be turning very windy indeed. exposed spots in northern scotland seeing gusts of wind in excess of 60 perhaps 70 mph. that could cause some disruption. 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, isobars squeezing together. indicative of a windy start. especially in northern scotland, we will keep some showers going through the day. most of the 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 for 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. what that means that the driest of the weather we found work to south and east, it closest to that area of high pressure. more chance of rain at times towards the northwest but for all of us it is going to remain mild.
