this is bbc news. i'm lewis vaughanjones with the latest headlines for viewers in the uk and around the world. president biden urges world leaders to unite and fight climate change together as he pledges to cut us emissions by at least 50% of past levels by 2030. this is the decisive decade. this is the decisive decade. this is the decade we must make decisions that will avoid the worst consequences of the climate crisis. the funeral of daunte wright, a black man shot dead after a routine traffic stop, has been taking place in the us city of minneapolis. well, we come today as the air fresheners for minnesota. we are trying to get the stench of

police brutality out of the atmosphere. india's covid crisis — the country records the world's highest—ever number of new infections in a day. buyer, by baby. baby, goodbye. # bye, bye, baby. # baby, goodbye. and the lead singer of the bay city rollers, hello and welcome to the programme. first, the un secretary—general, antonio guterres has claimed "the tide is turning for action" after a number of world leaders, including president biden, made new pledges to cut emissions on the opening day of a global climate summit. the us, canada, japan and south korea all announced revised targets but two of the biggest emitters,

india and china, made no fresh commitments. the latest data shows china is the world's biggest emitter of carbon dioxide estimated at 28% in 2019. the us was second at 15% and india was third at 7%. 0ur science editor david shukman reports. the more the world heats up, the more dangerous it becomes. that's what this is all about. more intense flooding in the uk and many parts of the world is more likely, while in some regions like central america, the big fear is droughts getting even worse. failed harvests are already forcing thousands to leave their homes. all of a sudden, we can see the whole, whole sphere... it's one reason why, with a video, president biden is making climate a priority. we knowjust how critically important that is because scientists tell us that this is the decisive decade.

this is the decade we must make decisions that will avoid the worst consequences of the climate crisis. this virtual gathering saw the leaders of the world's biggest economies, and some of its most vulnerable nations, all calling for action on climate change. we're suddenly getting a flurry of promises, counted in different ways, but all significant. the united states to cut its emissions by up to 52% by 2030. the european union, 55% by the same year. and the uk, 78% by 2035. china, the world's biggest polluter, says its emissions will fall from 2030, but president xi wants more developed nations to cut first. translation: developed| countries need to increase climate ambition and action and make concrete efforts to help developing countries accelerate the transition to green and low—carbon development. to make any real difference,

every country has to play its part, and despite all the talking in recent decades, the scale of the challenge has got even bigger — that's because human activity every year emits something like 50 billion tonnes of the gases that are heating up the atmosphere. now, scientists say that needs to come down by nearly half by 2030 to have any decent chance of keeping a lid on the rise in temperatures, and emissions should then fall to basically zero by 2050. but at the moment, the world is not heading in that direction. so, what's likely to happen? well, electric cars are on their way. we're going to see far more of them. fewer flights may be on the cards because prices may have to go up if there are charges for pollution. eating less red meat is another recommendation from government advisors, who say it'll save carbon. and heating our homes, not with gas boilers, but with heat pumps or hydrogen, but the details still need to be worked out.

we're working with everybody, from the smallest nations to the biggest emitters, to secure commitments that will keep change to within 1.5 degrees. but for younger people, this is all too slow. this earth day protest was in indonesia, and american politicians got a similar message from greta thunberg. we, the young people, are the ones who are going to write about you in the history books. we are the ones who get to decide how you will be remembered. so my advice for you is to choose wisely. already, green technologies are becoming far cheaper but the transition to a zero—carbon world will need a lot more political will and help for the countries most at risk, and all of that still needs to be negotiated. david shukman, bbc news. in minnesota, hundreds of people have attended the funeral of daunte wright,

the 20—year—old who was shot dead by police near minneapolis. the usjustice department announced a federal investigation into the city's police department on wednesday — the day after derek chauvin was convicted for the murder of george floyd. from minnesota, here's the bbc�*s lebo diseko. it's a moment no parent should have to endure — daunte wright's mother and father arriving at his funeral. mourning with them, the community in which he lived and was loved. i never imagined that i'd be standing here. the roles should be completely be reversed. my son should be burying me. sobbing. my son had a smile that was worth a million dollars. when he walked in the room, he lit up the room. he was a brother, a jokester and he was loved by so many. he's going to be so missed. daunte leaves behind six siblings and a son, dauntejr.

i didn't get to tell him i loved him before he left. he didn't deserve this. minneapolis. here, too, the families of george floyd and others of black people killed by police, lending their support to another enduring a pain they know all too well. daunte wright's life mattered! all repeat: daunte | wright's life mattered! it's almost two weeks since daunte was shot dead by police during a traffic stop. the officer, kim potter, says she meant to use her taser. she has since resigned and been charged with manslaughter. the wright family says this was murder. they want her charged and convicted as such. they said that, well, the real reason they stopped was because his tags had expired. well, i come to minnesota to tell you your tags have expired.

your tags of racism have expired. your tags of police brutality have expired. daunte's death has raised questions yet again about the value of black life in america, how it is that something so routine as an expired tag on a licence plate can result in the death of a brother, son and father. lebo diseko, bbc news, minneapolis. india's coronavirus outbreak is getting worse and hospitals in the indian capital delhi have run out of oxygen to treat seriously ill covid patients. india has reported the biggest daily rise in infections of any country since the pandemic began — nearly 315,000 cases — and it's feared this second wave hasn't even peaked yet. 0ur south asia correspondent rajini vaidyanathan reports. the scale of india's loss

is becoming hard to comprehend. thousands dying every day, each pyre a family in grief. and for some, it's turned to anger. my father is now dead. he was cold—blooded murdered. nobody else helped me. i called each and every hospital. i called all the oxygen suppliers. nobody helped me. vinay srivastava was a father and a freelance journalist. like so many others in india, he'd made a desperate plea on social media to find a hospital bed. ..he tweeted. a day later, his oxygen had dropped to 31. ..he begged. the last photo he shared, his finger attached to an oximeter showing a dangerously low reading. five hours later, he died.

covid—19 is crippling india's health care system. people are struggling to find icu beds, and oxygen is in short supply. we are the doctors, we are the hospital, we are supposed to give life. if we cannot give them oxygen even, we're in the situation where the patient will die. in delhi, dozens queued to buy oxygen canisters for their loved ones. today, many hospitals in the capital were perilously close to running out. this man's family spent the day searching for oxygen for him. his niece told me relatives drove five hours to find supply for today. they'll have to do the same again tomorrow. it's distressing. i can't imagine what his daughter, who's younger than me, my cousin, and his son, they must be going through right outside the hospital. they're stationed outside and running here and there at every lead to fill a cylinder or to get their oxygen.

a desperate second wave which many health experts believe could be down to a new strain of the virus — one they fear is more infectious and deadlier. rajini vaidyahathan, bbc news. i'm nowjoined by professor bhramar mukherjee. she is a professor of biostatistics and epidemiology at the university of michigan. thank you very much forjoining us on the programme. thank you very much for “oining us on the programmeh thank you very much for “oining us on the programme. thank you for having — us on the programme. thank you for having me — us on the programme. thank you for having me on _ us on the programme. thank you for having me on the _ us on the programme. thank you for having me on the show. - for having me on the show. we've seen in that report today and yesterday actually some really shocking images from india when we assume lots of people assumed things basically were under control. what do you think has been responsible here for things deteriorating so quickly? for things deteriorating so cuickl ? ., for things deteriorating so cuickl ? . ., for things deteriorating so cuickl? . ., quickly? yeah, so that, you know, quickly? yeah, so that, you know. last- _ quickly? yeah, so that, you know, last- the _ quickly? yeah, so that, you know, last- the first - quickly? yeah, so that, you know, last- the first wave l quickly? yeah, so that, you| know, last- the first wave in know, last— the first wave in india, the virus started declining from september 2020 and steadily declined until

february. but in the middle of february, we started noticing this uptick and i think the ferocity and the velocity that we are seeing in like a vinous inferno is like a confluence of different factors, it is a lapse of covert appropriate behaviour as soon as the country opened weddings were happening, massive election rallies were going on, religious gatherings were happening, cricket matches were being played, shopping centres and restaurants opening and kids went back to school and we need immunity from past infection probably also contributed but even with all of these factors folder then it is very hard to explain the exponential surge that you are seeing in india without the potential of more transmissible mutant data circulating in the country. mutant data circulating in the count . ,, ,, �* mutant data circulating in the count . ,,,, ~ g , mutant data circulating in the count . ~ g , ., mutant data circulating in the count . ~ g , country. crosstalk. just to be clear, is that you _ country. crosstalk. just to be clear, is that you pointing - country. crosstalk. just to be clear, is that you pointing to i clear, is that you pointing to variants, then? new variants that are right across the world that are right across the world that we're all worried about, you think it must be a

now it's turning to its state owned companies to persuade or pressure millions more people to get vaccinated. 0ur china correspondent robin brant reports from yiwu near the east coast. music. here we are again. we've come back to zhejiang hospital in this district of yiwu because it was here six months ago that we discovered they were doling out the vaccine for the first time in china, we think the first time in the world, to anyone who wanted it. any member of the public could turn up, pay their money, get the jab. what's happening here in china is it's being rolled out to the public. six months on, here we are again. china's ramping up its inoculation programme. so, we've come here to find out who's getting it, why they're getting it, do they trust china's vaccines and do people feel like they're being forced? i don't think she's got the jab, but let's ask her anyway.

the village asked you to come to get your vaccine? really important for china and for yiwu. more important. do you think people here should be forced to take the vaccine? your choice? 0k. it's the best interview i've ever done through a helmet. look, everyone, it's bbc. be careful about your words. laughter. let's look at the numbers because scale is huge here.

china currently has four homemade vaccines on offer, tou can't get foreign ones. 200 million people so far have been vaccinated, and it's aiming for 40% of the population inoculated by the end of the summer. have you had the vaccine? oh, good, 0k. feel 0k? six months ago, there was no pressure. now, though, china really ramping up its inoculation, and there is pressure. there's pressure from people personally, theirfamilies. there's pressure in terms of the country and opening up again, particularly here in this city that depends on business. but we've also heard about, you know, pressure in compounds, universities, people being told you can't live here or can't study here unless you get this vaccine.

clashes have erupted in eastjerusalem between israeli security forces and rival demonstrations by palestinians and a far rightjewish group. hundreds of activists from the ultranationalist lehava group shouted �*death to arabs' and �*revenge' as they marched towards the city's damascus gate where palestinians had gathered in a counter protest. there were confrontations between the two sides, and between palestinians demonstrators and the israeli police, who were trying

to keep the groups apart. dozens of people have been hurt. the bay city rollers singer, les mckeown, has died suddenly at the age of 65. the band — which had hits with tracks like �*bye bye baby�* and �*shang—a—lang' — experienced a level of fan hysteria similar to the beatles in the uk and the us during the 1970s. lets take a listen: # bye bye baby. # bye bye baby. # bye bye baby. # bye bye baby. # don't make me cry. # you other one girl in town i'd marry. —— are the one. adored by teenagers, who copied the rollers tartan look, they became one the biggest pop sensations the uk has ever seen. they were hugely successful, selling more than 120 million

records worldwide, and according to some, the invention of boy bands became an industry thanks to the bay city rollers. we can now speak to the music promoter sean mclusky, a very close friend of les mckeown and his family. thank you so much for coming on the program. a difficult time for you. we will come on in a second with the songs and hits and fashion but first of august your reflections are somebody who knew him so well. this must a difficult time. it who knew him so well. this must a difficult time.— a difficult time. it definitely is a difficult _ a difficult time. it definitely is a difficult time. - a difficult time. it definitely is a difficult time. i - a difficult time. it definitely is a difficult time. i knew i a difficult time. it definitely. is a difficult time. i knew les mckeown and first met him in his wilderness years after his global success after his solo career injapan when he was backin career injapan when he was back in the uk after taking the world by storm. and just sort of making a new life for himself. i always knew about his cultural significance and i was really aware of his history

that is it from me. you can reach me on twitter — i'm @lvaughanjones. i'm lewis vaughnjones and this is bbc news. hello. we're seeing big temperature differences from night to day at the moment. we started yesterday morning at around —6 in a few spots. thursday afternoon, under clear skies, sunny skies, you can see from the satellite imagery, we got to 17—18 degrees. problem is, as soon as you lose that sunshine, the temperatures plummet again. and this morning, another widespread frost across the country, maybe as low as —3 or “4 in some spots of england and south—east scotland. frost—free towards the north but that's because we've got more cloud, even though we're under this same area of high pressure. that's what's keeping things dry at the moment. but around it, we are seeing some blustery conditions, particularly towards the far south and the west. most, though, light winds through friday, early morning mist and fog patches quickly clearing. that cloud stubbornly persistent across the far north—east of scotland, maybe

a few showers for shetland. high cloud may turn the sunshine hazy in one or two spots, but overall, it's a sunny day for many. a windy one, though, through the english channel and the south—west. the winds could gust in excess of a0 mph, whipping up some rather choppy seas, and that will limit the temperature rise here to between around 12—14 degrees for many. it may get up to 18 on the north coast of devon and around these western areas — 18 celsius quite possible. northwest england, north wales could get to around 20 degrees during the afternoon. but for all, just about, away from where we've got the cloud in the north—east of scotland, it's going to be a day of high tree pollen. now, as we go into friday evening and overnight, we could see the odd mist or fog patch form. the cloud still there in the far north—east of scotland, but for most, it's clear skies into the weekend. and high pressure is still there as we start it. now, with that high pressure strengthening a little bit to the north—east of us, it does mean the winds across the south and the west will start to strengthen a little bit more, so it will be another blustery day

across southern and south—western areas of the uk. breeze picks up a little bit for the rest of us. still some cloud in the north—east of scotland. a bit of patchy cloud forming elsewhere but for most it's another sunny day. cool down some of those eastern coasts, but in the west, we could still get up to around 17—18 degrees. the frost becoming less abundant as we go through this weekend as the breeze picks up. and it will pick up further into sunday, bringing more cloud across the country. cloudiest of all, central and eastern parts of england, best of the sunshine in the west, with the highest of the temperatures. but a cool day down those eastern areas, especially where the cloud lingers. and there'll be more cloud and cooler conditions next week, too.
