this is bbc news with the latest headlines for viewers in the uk and around the world. president biden hosts a virtual climate summit with world leaders and pledges to cut america's carbon emissions by at least half. we're here at this summit to discuss how each of us, each country, can set higher climate ambitions that will in turn create good—paying jobs, advance innovative technologies and help vulnerable countries adapt to climate impacts. # go home to my lord and be free...# 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're trying to get the stench of police brutality _ out of the atmosphere. india buckles under the impact of the covid pandemic — the country records the world's highest number of infections in a day. a formal uk government apology after failing to commemorate properly more than 100,000 black and asian people who died fighting for the british empire during the first world war. 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 it's 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 has this report. 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.. i 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. 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! 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 more than a year ago, more than 315,000 cases.
and it's feared this second wave hasn't even peaked yet. 0ur south asia correspondent rajini vaidyahathan 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. the indonesian navy is continuing to search for a submarine with 53 crew members on board which went missing during a torpedo drill on wednesday, and time is running out to save those on board. the navy's chief of staff says the nanggala only has oxygen to last until saturday.
i'm joined now by natalie sambhi. she's an expert on indonesia's military and security. we can speak to her live from perth. it is very good for you to give us your time. what is our understanding of what we can expect about the submarine before we get to it self in the military equipment bring us up—to—date with what you know about it. up-to-date with what you know about it. ~ , , ., y up-to-date with what you know about it. ~ , ,., , ~ , up-to-date with what you know about it. ~ , , ~ , ., it. absolutely. at this moment there are facts that — it. absolutely. at this moment there are facts that are _ it. absolutely. at this moment there are facts that are not _ it. absolutely. at this moment there are facts that are not confirmed - it. absolutely. at this moment there are facts that are not confirmed butl are facts that are not confirmed but the priority is located in the submarine and then finding out whether or not the crew is still alive. at the moment there is a singaporean rescue vessel and a malaysian rescue vessel in the area above the singaporean vessel will only reach the site to sleep by saturday. only reach the site to sleep by saturda . �* ., , , ., saturday. and what is your understanding _ saturday. and what is your understanding of - saturday. and what is your understanding of how- saturday. and what is your understanding of how this | saturday. and what is your - understanding of how this happened with matt how the submarine could have gone missing?— with matt how the submarine could have gone missing? again there are a number of scenarios. _ have gone missing? again there are a number of scenarios. the _ have gone missing? again there are a number of scenarios. the theory - have gone missing? again there are a number of scenarios. the theory at i number of scenarios. the theory at the moment is there was a power outage during the drill and the submarine sank to a depth of between 600 and 700 metres. but at this point it is not known if we take the san juan
point it is not known if we take the sanjuan argentinian summer in the sink a few years ago, again that was a power outage caused by water leaking into a battery pack and was with this point there are a number of scenarios but the power outage theory seems to be the most prominent. theory seems to be the most prominent-— theory seems to be the most rominent. �* .., ., prominent. and it will come to the submarine — prominent. and it will come to the submarine itself, _ prominent. and it will come to the submarine itself, tell— prominent. and it will come to the submarine itself, tell us _ prominent. and it will come to the submarine itself, tell us a - prominent. and it will come to the submarine itself, tell us a little . submarine itself, tell us a little bit more about it because from my understanding, it's pretty old. yes. understanding, it's pretty old. yes, it is not unusual _ understanding, it's pretty old. yes, it is not unusual for _ understanding, it's pretty old. yes it is not unusual for militaries around the world to operate older platforms, but that is well is on mrs platforms been well maintained. this piggly submarine, a westerman one, has been with the indonesian navy since 1991 in his head to refit since then. a complete refit in 2012 by south korea. so to some degree it was seaworthy, it was operational but these platforms are only as good as a maintenance systems and so if these submarines or any platform for that matter can be well resourced and the skills and knowledge maintained and they can continue a little bit further. but obviously it is indonesia's intent that it's submarine fleet and the rest of its
navy be modernised because simply it is more difficult and more expensive to maintain ageing platforms. so is more difficult and more expensive to maintain ageing platforms. 50 in to maintain ageing platforms. so in that case, to maintain ageing platforms. so in that case. in _ to maintain ageing platforms. so in that case, in terms _ to maintain ageing platforms. so in that case, in terms of— to maintain ageing platforms. so in that case, in terms of indonesia possible enable hardware, if you talk us through a little bit about how it compares to other countries with more money to invest in their military infrastructure.— military infrastructure. indonesia ist in: military infrastructure. indonesia is trying to _ military infrastructure. indonesia is trying to invest _ military infrastructure. indonesia is trying to invest more - military infrastructure. indonesia is trying to invest more in - military infrastructure. indonesia is trying to invest more in terms | military infrastructure. indonesia l is trying to invest more in terms of its naval modernisation but if you look at navies in the region like singapore, the indonesia capability is a hind that. indonesia has got rid of resource constraints, a large population deal with in all sleep —— obviously with kevin nothing as well so there are other pressures but its defences have been more of a priority in recent years but has much more catching up to do. interesting to speak to you. an expert on the indonesian military and security. thank you so much for your time. and security. thank you so much for yourtime. fascinating and security. thank you so much for your time. fascinating stuff, thank

wednesday sitting somehow uneasily with the abiding memories at the shame of watergate. and lift—off of the space shuttle discovery, with the hubble space telescope, our window to the universe. this is bbc news. the british prime minister has offered an "unreserved apology" for the failure to commemorate properly the deaths of tens of thousands of black and asian troops who fought for the british empire during the first world war. the commonwealth war graves commission found that at least 116,000 people who died weren't given headstones because of what they call "pervasive racism". mark easton has the story.
the imperial war graves commission was established with a remit to remember every individual who died for their country regardless of rank, class, religion or race. in france, the immaculate thiepval memorial is an example ofjust that. but outside europe, the commission enacted a policy of discrimination, categorising the fallen as white, indians or what it called "natives". this village in punjab, then part of british india, sent 460 men to fight in the first world war, the largest number of any village in south asia. and yet the war dead are not named. a shock to a british gp who went to research his ancestors from there. i just came across the whitewashing of history when it came to the world wars. and growing up born and bred in nottingham, in history lessons, i never saw a photograph or any story of a black soldier or an indian soldier. in southern kenya, white war dead lie beneath named memorials in a well—tended cemetery.
beyond the fence is where their african comrades are buried — no names, no gravestones — a legacy of this man, lord arthur brown, who headed the war graves commission in the 1920s and believed that african natives were not civilised enough to appreciate individual headstones. unlike the war graves at this south london cemetery, today's report finds at least 116,000 casualties of world war i, mostly africans and indians, were not commemorated by name or were not commemorated at all, a consequence of pervasive racism. it was a policy encouraged by winston churchill, then secretary of state for the colonies. shortly after sunrise, a bugler brings the dusky warriors... . the commission has known for years there were significant issues with the way black and asian servicemen had been honoured, a century too late. today, the prime minister
gave his personal backing to an apology delivered in the house of commons. i want to apologise for the failures to live up to their founding principles all those years ago and express deep regret that it's taken so long to rectify the situation. they are inviting me to come and have a conversation that's going to be very difficult to have and have somebody like me pointing out what they should've done years ago without glorifying colonialism and without glorifying the empire. there are promises to act, but true healing will take time. not only has there been a great historical injustice to black and asian servicemen, but our nation's story has been missing vital pages. mark easton, bbc news. china has vaccinated more than 200 million people since it first began rolling outjabs to the pubic six months ago. it was slow to start — covid has been all but eradicated there for months now — but it's borders remain effectively closed.
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 one city 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 cos
the scale is huge here. china currently has four homemade vaccines on offer. you can't get four on 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 wrapping 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.
finally, could this be the beginning of life on mars? in an extraterrestrial first, nasa's perseverance rover has succeeded in producing pure oxygen from the atmosphere of the red planet. a toaster—size device on board the unmanned vehicle converted carbon dioxide into sufficient oxygen to allow an astronaut to breath for ten minutes.
c02 makes up nearly all of the martian atmosphere. nasa described the experimental technology as a critical first step towards seeing humans on mars. 0ur science correspondent jonathan amos has the latest. this is another technology demonstration on the perseverance rover mission to mars. so, when the robot landed in mid—february, it took a number of experiments with it. one of them you'll know, which was the helicopter that it flew this week. the second one was to trial making oxygen from the atmosphere of mars. now, mars' atmosphere is dominated by carbon dioxide. something like 96% by concentration is c02. and if astronauts are ever to go to mars and live off the surface, then in all likelihood they'll have to find their oxygen and maybe some of their water locally. they won't be able to take it all with them. so, this experiment, it's called moxie.
the device itself is about the size of a toaster. it's able to strip oxygen atoms out of carbon dioxide molecules. so, carbon dioxide is one carbon atom and two oxygen atoms. so, it takes those oxygen atoms away to make molecular oxygen, which we can breathe. and the exhaust product, the by—product, if you like, is carbon monoxide, which can be simply vented. now, in this instance, because it's just a trial, the amount of oxygen produced was quite small, so we're talking about five grams over the course of an hour. five grams is about enough for an astronaut to breathe for ten minutes. but you can imagine down the road in the years hence that they would be able to develop next—generation machines, and these might be able to put out tonnes of oxygen. cos that's what you would need, tonnes of oxygen. notjust to breathe, but also to use in rocket engines, because if you're down on the surface of mars
as an astronaut, you need to get off as well to come home. you certainly do. our thanks to jonathan and thank you for watching. 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 southeast 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 northeast 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 southwest. 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 northeast 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 northeast 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 northeast of this, 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 southwestern areas of the uk. breeze picks up a little bit for the rest of us. still some cloud in the northeast of scotland.
a bit of patchy cloud forming elsewhere, but for most it's another sunny day. cool down some of those eastern coast, 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.
the headlines... president biden has promised to cut america's carbon emissions by at least half before the end of this decade. he called on other leaders at a virtual climate summit to take decisive action. the funeral has been held in minneapolis for daunte wright, a 20—year—old african—american man shot dead by police earlier this month. the officer said she meant to use an electric shock device on him, but mistakenly pulled herfirearm instead. india has recorded the highest single day total for new covid—19 cases seen by any country so far in the pandemic. deaths from coronavirus reached a new high on thursday, and hospitals are struggling to cope. the uk government has apologised for failing to commemorate properly more than 100,000 black and asian people who died fighting for the british empire during the first world war.
