afghanistan could be starving within weeks unless the world stepped in to help. the winter months are coming, we are coming out of a drought. the next six months are going to be catastrophic. it is going to be catastrophic. it is going to be catastrophic. it is going to be hell on earth. and after 600 days, the united states finally reopens its borders too much of the world's population. hello. welcome to our viewers on pbs in america and around the globe. we begin at the cop26 climate conference in scotland where barack obama has taken centre stage, urging young people to stay angry, as he put it, in their calls for more action. after a reception, he said the world is nowhere near where it needs to be in tackling climate change. the former us president also followed the lead ofjoe pride ——joe biden in followed the lead ofjoe pride —— joe biden in scolding leaders for not attending in person. ourscience leaders for not attending in person. our science editor was at the conference. deeper floods. biggerfires. higher temperatures. climate change is being felt around the world, so the talks in glasgow are notjust about the future, they're about coping with a hotter and more hostile planet right now. pushing for an urgent response is the former us president barack obama. getting a rock star reception here and saying it's not too late. our planet has been wounded by our actions. those wounds won't be healed today or tomorrow or the next. but they can be healed. and addressing young activists, he appealed to them to keep up the pressure for change. the most important energy in this movement is coming from young people. applause they have more at stake in this fight than anybody else. you are right to be frustrated. folks of my generation have not done enough to deal with a potentially cataclysmic problem that you now stand to inherit. many young people have suffered cataclysm already. a typhoon in the philippines eight years ago claimed 6,000 lives, and one survivor, the daughter of a fisherman, fears more violent weather to come. i have seen death myself, i have seen my family struggle. i still have so many dreams in this lifetime. i'm just 2a years old. i still want to have my family. i still want to have children. but i don't even know if they will have good future ahead of them. and with emotions running so high, activists here say even mr obama has broken a promise, to get climate aid to the poorest countries. we don't want to talk to him, what we need is action. he already knows what we want, he already knows what the people want and that is the us$100 billion pledge that he pledged in 2009 in copenhagen. more and more people are enduring the kind of extremes that scientists have long warned about as the planet heats up. so this is a chance to prevent a bad situation from getting worse. david shukman, bbc news. ican speak i can speak now to the founder and president of the pacific institute, and a world—renowned expert on climate and water issues. peter, thanks for joining us again. ito ask you first, where barack obama saying the world is not doing enough and yet we have had commitments even in the course of this summit on deforestation, on methane for example, on financing. which if carried through start bringing that global warming figure down and down. in a sense, is he right? and down. in a sense, is he riuht? and down. in a sense, is he riiht? ,., and down. in a sense, is he riuht? ., , right? 50 both of these perspectives _ right? 50 both of these perspectives are - right? 50 both of these l perspectives are correct. right? 50 both of these - perspectives are correct. the president, 0bama, perspectives are correct. the president, obama, is correct in saying we haven't done enough, and yet we are making progress at the meeting in glasgow. there have been new commitments that are better than any commitments we have had in the past. it is too soon to say whether this conference will ultimately be a success or a failure, but there is absolutely progress being made, and i think we need to give it and i think we need to give it a little more time, and again, the president is correct, we need to do much more, we should have been doing much more over the last many decades. i suppose we look for tipping points in a way, don't we? there is clearly a sense of some momentum behind the corporate swing behind a lot of climate action. is at the moment you look back on and say once you get buy in from the private sector on this scale, i think we were talking about $130 trillion being available through these corporate �*s, things really will change and could change quickly. that things really will change and could change quickly. that is a very important _ could change quickly. that is a very important point. - could change quickly. that is a very important point. there i could change quickly. that is a| very important point. there are a look a lot of tipping point. i am a scientist, we have what is seen as tipping points showing us humans are already changing the climate. we have also seen political tipping points, the incredible energy from the youth these days has helped drive the politics forward faster than some pessimists feared it would move forward, and we are seeing tipping points in the corporate sector as well. we are seeing commitments to end funding for fossil fuels, commitments to end funding for fossilfuels, coal, oiland fossil fuels, coal, oil and gas, fossilfuels, coal, oiland gas, and if the banks come on board and the countries come on board and the countries come on board and the countries come on board and cooperation come on board, we could see faster action than many of the pessimists had feared. but again, there is still a lot to be done and a lot remains to be seen what happens at the conference.— seen what happens at the conference. ~ . ., conference. we have lived for . uite conference. we have lived

yet enough to reach the target that we need to reach, but we need more than commitments. we actually need follow—through on those commitments, and one of the commitments that was made more than a decade ago for example was to provide 100 alien dollars to developing countries to help them reduce emissions and prepare for impacts that we can no longer avoid, and we have not met that commitment, the richer countries of the world have not provided that hundred billion dollars. so we need the commitments but we need the actions as well.— actions as well. that is the road ahead. _ actions as

attempting to force their way over to the polish side, and in response, poland palme government has ordered 12,000 troops to patrol the border. the eu says belarus wants revenge for the sanctions against it imposed because of human rights violations. accused of directing the surge of human traffic, president lukashenko's regime, which is welcomed in five thousands of migrants from around the world and is now pointing the way to the border with poland. but at that border, this was the welcoming committee. if the site and might abolish military helicopter was intended to turn them back, it didn't work. neither did the tear gas. soon, they were trying to prise their way through to their goal, eu soil. the polish authorities themselves accused of putting migrants back over the border illegally in recent months released this video to show what they are dealing with. this crisis have been brewing for months. six weeks ago we found these men who had been trapped in the forest between belarus and poland.— belarus and poland. belarus would push _ belarus and poland. belarus would push us, _ belarus and poland. belarus would push us, they- belarus and poland. belarus would push us,

on the greek macedonian border during the syrian migrant rises more than five years ago. president lukashenko who has enjoyed a sharp ausmat support claims all this is the eu's fault. but the european union says he is weaponising migrants in retaliation for sanctions. tonight, it is not more than 3000 are stranded on the border as the temperature falls low zero. let's get some of the day's other news for you. the us congressional investigation in into the deadly assault on the capitol building injanuary has formally requested testimony from six more people linked to donald trump, including top aides from his re—election campaign. more than 100 people are reported to have already testified about the storming of the capital. the pakistani government says it has agreed a ceasefire with local alabama militants. the move was confirmed by the band movement, ttp, which said the halt and violence would initially last a month. talks between the two sides are begun last month in afghanistan. thousands of ttp fighters are thought to be based in afghanistan. the new chairman of yorkshire county cricket club has said the former captain as rafiq should be praised for his bravery in blowing the whistle on the racism he suffered as a player. lord patel who has been drafted into lead yorkshire troop perhaps writers dwell in its history also apologised. the players that he now hope that there would be change. new york, here we come! that was one excited passenger this morning in london, boarding a plane to the us. america lifted the pandemic travel ban would have kept people out of the country, indeed from more than 30 other countries for some 20 months. there were joyful months. there werejoyful reunions at airports in the us as families who have been separated were together at last. 0nly vaccinated travellers can enter the us. we spent the day atjfk airport in new york. cheering that first embrace, that flood of relief. none of them could have predicted they'd spend such a long time apart. the international arrivals floor of new york's kennedy airport sprang to life with heart wrenching transatlantic reunions as passengers deplaned the first flights from london heathrow. and ran into the arms of loved ones. it's the best thing ever in the whole world. it's been so emotional and it has for millions of families all over the world, but this is the best thing that's ever happened to me. sisters gill and louise haven't seen each other in two years. thank you so much. what are you guys going to do now? just keep hugging each other! not being able to touch my sister and them not hugging my children has been the hardest part of it all. so many like the matthews have missed out on precious moments they can never get back. so they've missed the birth of my son, so he's 3.5 months now, so finally they get to meet him. and they haven't seen him since he was crawling and now he is a fully walking toddler with opinions and so it's going to be really fun for them to spend all this time with him. airlines are hoping for many more scenes like this in the coming weeks. it's a major milestone for separated families and it's a lifeline to the tourism industry right ahead of the winter holiday season. there is a much more, i think, pragmatic framework in place which is becoming more universal to allow travel to exist alongside the pandemic. the ban was symbolically lifted with a dual take—off between virgin atlantic and british airways. even with a watchful eye on covid case rises in europe, they're optimistic they can avoid any more turbulent family separations. nada tawfik, bbc news, new york. you can see the joy for yourselves. we are joined you can see the joy for yourselves. we arejoined by erin who lives in los angeles, and

in august and then he came to three months in october and left january 2020, and that was the last time he set foot in the last time he set foot in the united states. there is a nine month period when we didn't know when we would see each other again when the pandemic hit and there was another six—month period, but i am one of the lucky ones. i was able to get special permission from the french government to visit him in the middle of the pandemic because we were part of an unmarried couple. you are lucky could be because others didn't get that opportunity. it is going to be quite strange, isn't it? do you feel some apprehension along with the excitement? honestly, all i feel is excitement. you know, it's nearly two years waiting for the borders to open and it is like i can breathe again for the first time in years. there are no more barriers between me and my partner, and to be able to say that means everything. yes, how have you felt about that travel ban because it has been very restrictive but it has been there for a very good reason. yes, i think that is a really tough issue with a lot of complicated points to it, and it did keep a lot of people apart but it was therefore a good reason, as you said. so i think it isjust good reason, as you said. so i think it is just a difficult, complex issue that i couldn't even begin to touch on now. well, you don't have to because you can keep ripping the pages of the calendar into december, won't be too long now. erin, thank you forjoining us. thank you for having me, it was great. still to come on bbc news, the story of how one heroic dog and his handlerfrom the story of how one heroic dog and his handler from the second world war are being commemorated here in the uk. the bombastic establishment outsider donald trump has defied the pollsters to take the keys to the oval office. i feel great about the election results. i voted for him because i genuinely believe that he cares about the country. it's keeping the candidate's name always in the public. eye that counts. success or failure depends not only on public display - but on the local campaign l headquarters and the heavy routine work of their women volunteers. i berliners from both east and west linked hands and danced around their liberated territory. and with nobody to stop them, it wasn't long before the first attempts were made to destroy the structure itself. yasser arafat, who dominated the palestinian cause for so long, has died. palestinian authority has declared a state of mourning. after 17 years of discussion, the result was greeted with an outburst ofjoy, leaving ministers who long felt only grudgingly accepted among the ranks of clergy suddenly felt welcome. welcome to bbc news. i'm david eades. the headlines: barack obama urges the young people of the world to stay angry over climate change as he speaks at the un summit in glasgow. poland accuses belarus of trying to trigger a major confrontation along the border as it attempts to stop thousands of migrants from getting into the country. millions of people in afghanistan are facing starvation if somebody does mr ben. that's the warning from the united nations. the head of the world food programme says that the country faces being turned into hell on earth. he said 95% of people they already do not have enough food as winter approaches. many of the problems predate the return of the taliban to power, but a lack of foreign aid is also playing a part. our world affairs editor john simpson reports. winter's coming, and it looks like being a bad one. camels are on the move to warmer areas. we are heading west out of kabul through the taliban roadblocks. it's not long before we reach the snow. injalrez district, food aid is being distributed, flour to make bread. everyone here knows that things are likely to get really bad in a few weeks. "there is a real possibility we'll be frozen this winter," this man tells me. these people are so poor they can't afford to buy food orfuel for heating. a humanitarian disaster could bring the taliban down, so they are cooperating with the international aid agencies, even if they don't like them. the head of the world food programme, visiting kabul, doesn't mince his words. the winter months are coming, we're coming out of a drought. the next six months are going to be catastrophic. it's going to be hell on earth. we reach bamiyan, an agricultural centre which has been hit by drought, like many other parts of afghanistan and, of course, there was an infamous taliban crime here. a couple of hundred yards along the cliff from the place where the statues of the buddhas used to stand, until the taliban destroyed them, a woman called fatima lives. she's a widow raising her seven friendly, intelligent children on her own. before the taliban took over, she got by with occasional food aid and the money she and her eldest boy earned from weeding the fields and herding sheep. but the drought has put an end to all of that. and food aid doesn't reach here. within weeks, they could all be starving. "some women sell their daughters for marriage," i say, "would she?" "if it was absolutely necessary to keep everyone alive," she answers, but she would hate it. listening to all of this, it was hard not to think of your own family. imagine of this was your little girl or your little boy or your grandchild about to starve to death, you would do everything you possibly could, and when there is $400 trillion of wealth on the earth today, shame on us that we would let any child die from hunger. fatima's children leave for school, those who are allowed to go. like millions in this country, their lives are under real threat. the next few months will decide. john simpson, bbc news, bamiyan. in sierra leone, a mass burial is taking place for almost 100 people killed in a fire on friday, abbe starting after fuel tanker collided with a drug on a busy road. the nationbuilding president has declared three days of national mourning. a west africa correspondent reports. heading to theirfinal heading to their final resting place, this mortuary was overwhelmed with bodies in the immediate aftermath of friday's blaze. now, it is sending them to a mass burial site in a country that has already suffered many disasters, this one stood out. medical emergency of this magnitude i have never experienced before and all of my career as a medical doctor. this is big, really massive, and when i saw the incident, when i came to this hospital and i was called i was really taken aback to see what happened, and we are still yet to understand what happened because it is just too soon. at because it is 'ust too soon. at the because it isjust too soon. at the scene of the accident, reminders of friday's horror. it has been more than 48 hours since the blaze and there is still smouldering ash and the smell of rubber hanging in the air. this is one of the city's poorest neighbourhoods and the inhabitants are having to deal not only the of their livelihoods but also with the death of loved ones and neighbours. this woman'shouse was burned in an electric buyer back injuly, now she has lost her pharmacy as well. for all of the nights i am crying, i don't know how i am going to start my life for me and my sister because it is not easy for me. i have lost my pharmacy, my house, i do not know how i am going to start my life. locals have gone through more collective trauma than most. the country has been rocked by civil war, the country has been rocked by civilwar, natural the country has been rocked by civil war, natural disaster. now, one more challenge they must all overcome. here is a rather nice story for you, and heroic dog and his handler in the second world war have been commemorated by the community in the uk. a statue ofjimmy muldoon and his shepherd dog, khan has been unveiled. they came under heavy enemy fire in holland. together forever in bronze. lance corporaljimmy muldoon and his dog stop khan the german shepherd who served alongside them and save the solder�*s lie. in 1944 in holland, they were thrown into the sea, and jimmy was in trouble. it was an assault, the craft they were in. it got bombarded and sank, and it left everybody in the water. the dog managed to get to the shore, but you could hear the handle on the water, my father. he ran down, jumped back in, gotten by the scruff of the neck and pulled him out. i think it was about 200 yards to shore. after the war, khan had to be returned to his owners, a family emissary. he was awarded the dickin medal, the animalversion of the victoria cross. they decided he would take him home. . . , they decided he would take him home. ., ., , ., home. khan was treated in lanarkshire _ home. khan was treated in lanarkshire as _ home. khan was treated in lanarkshire as a _ home. khan was treated in lanarkshire as a hero. - lanarkshire as a hero. he used to get free meat from the local butcher, he was well looked after. what do you think your father would make of it? he would be over the moon, he would, yes, indeed. it is going to be a strange feeling walking through that green, watching that statue. it is going to be very strange. now, how much would you pay for address once worn by anyone else? right here, we just sold the dress. — right here, we just sold the dress, sold, sold, sold! $180,000 for the halter mini dress which she wore in belgrade, june, 2011, just one month before her death at the age of 27. it is 16 times what they expected. that is bbc news. thanks for watching. hello. we have some pretty quiet weather to come across the uk in the next few days. but the end of the we could definitely offer is something rather more dramatic. for now though, it's about light winds and those winds coming in from the south—west or the west will bring some relatively mild air. this amber colour behind me showing air that's been pulled in quite a long way south across the atlantic indicating quite a warm feel to tuesday across parts of england and wales. you may have noticed some colder air to the far north of the uk. temperatures will struggle to get the double figures across northern most scotland with some squally showers here. elsewhere, we are looking at i think at the low to mid—teens, there will be some rain to the day for northern england and wales. but we should see brighter skies north of the front for much of scotland and northern ireland, and to the south across southern and eastern england. and in this front is set to stick around through wednesday and thursday, slowly making its way south across the uk. turning things quite murky, i think, across southern and eastern england into the small hours of wednesday, but it will stay very mild here. that slightly colder air sneaks further south into scotland into the small hours of wednesday. we could see a patchy frost inside some of the sheltered glens to the north. here's our front on wednesday, still lurking to the south of the uk. it's looking much clearer further north. for scotland and northern ireland, there should be some sunshine, just the chance of a few scattered showers in the far north and west. some sunshine for northern england and wales and an improved picture on tuesday. whereas for southern and eastern counties of england, it will be much grayer, much gloomier and there's a chance some patchy rain on and off. and then for thursday, still the remnants of that weather front close to the south of the uk could mean some thicker cloud around here for a time and a little bit of rain. but actually for thursday, we are largely focusing on a ridge of high pressure and a lot of fine weather and light winds. i think potentially some rain getting into northern ireland by the end of the day, and the wind starting to kick up and here's why. this area of low pressure looks like it could deepen to the end of the week and come swinging our way from the atlantic. quite a bit of uncertainty as to when and where exactly on friday that low will move in, but do keep it in the back of your mind as the potential for strong winds on friday. hello. welcome to bbc news. our top stories: barack obama ba rack obama has barack obama has urged the young people of the world to stay angry over the climate as he addressed the un summit in glasgow stop he also followed the lead ofjoe biden scolding china's and russia's leaders for not attending in person. colin is accusing belarus of trying to trigger a major confrontation along the border as it attempted to stop thousands of migrants from getting into the country. poland palme government—held crisis meetings on monday and deployed 12,000 troops to control the border. after 600 days, the us has finally lifted the pandemic travel ban which has kept out people for more than 30 countries. there were joyful reunions at airports in the us as families who have been separated were together at last. 0nly vaccinated travellers can enter the united states.
