welcome to bbc news. i'm gareth barlow. our top stories: the united nations is warning half a million children under five are at risk of death by the middle of next year. we meet one family dealing with the direct impact of climate change before this last drought, dahirand his family were doing 0k. they had fields and crops, they had six cows and some goats. they were middle—class farmers. suddenly left destitute, bankrupted by drought and by climate change. world leaders are in bali for a summit of the 620 group of nations. high on the agenda — the energy crisis, the war in ukraine, and the stability of the global economy.

presidentjoe biden shook hands with xijinping for the first time since taking office and played down fears of a confrontation with china. i absolutely believe there need not be a new cold war. i have met many times with xijinping and we were candid and clear with one and other across the board. one of the world's richest men, the amazon founderjeff bezos, pledges to give away most of his wealth. eight billion and counting — the world's population hits another milestone as it doubles in less than 50 years. and exactly 100 years ago, the bbc began radio broadcasts in britain.

already on the front line of climate change, somalia is enduring its worst drought in a0 years. and the presence of one of the deadliest islamist extremist groups, al shabab, complicates the distribution of aid. the united nations is warning that half a million children under the age of five are at risk of dying by the middle of next year. somalia urgently needs another billion dollars in humanitarian aid. six weeks ago, we brought you andrew harding's first report from the town of baidoa. he's now returned there, to the heart of the crisis, and a warning — you may find some of the images in his report distressing. we're tearing through baidoa. our guard is driving faster than on our last visit. the threat of ambushes by islamist militants is growing here. suddenly, we stumble across a funeral, for a six—year—old boy who starved to death yesterday. 11 more children were

buried here this week. but it's one particular family that's drawn us back to a desolate camp on the edge of town. fatouma mohamed is heating breakfast for her children — a cup of tea. they will eat late in the day. nice to see you again. we have returned to see how the family is coping. hi, dahir. this was dahir here six weeks ago, mourning his younger brother salat, who died of hunger on the journey into baidoa. today, he's in good spirits. she's feeling hot? but his two sisters are now struggling. they have suspected measles. perhaps pneumonia, too. the illnesses that seem to feast on hunger.

and which lead so often to this. in a nearby hospital, this two—year—old looks like a burn victim. in fact, her body is reacting, painfully, to prolonged starvation. as on our visit last month, the ward here is still full of such cases. does it feel to you like the world is paying attention now to somalia? now we can say that the attention of the international community is on somalia, especially the droughts here. so, you are getting more aid because of that? we are not getting enough, but we hope it will come soon. it's a desperate situation. back at the camp, 11—year—old dahir is heading to school. he's bright, alert. our presence might be part of that but around him — listless children and

a chorus of coughing. the teacher tells us that most of his class struggle to attend or to focus. many here will be stunted for life. across the road a sudden crowd. a mood of near panic as frustrated mothers try to register for new food hand—outs, but there is not enough. it's overwhelming. we are not getting the resources on time with adequate amounts. you're only getting half what you need, is that right? that is exactly the right picture, we are getting half of what we want. later in the day, fatouma hauls water home for her children. dahir here is quick to help out. "i'm getting by," she says, "but my children are not well. "i must work to make sure they survive." coughing

somalia is struggling right now, but it is worth remembering that before this last drought, dahir and his family were doing 0k. they had fields and crops and six cows and some goats. they were middleclass farmers. suddenly, left destitute, bankrupted, by drought, by climate change. inside their heart, the girls slump. do you worry about yoursisters, dahir? he says yes, he does. what do you worry about? we are straying here towards painful memories of dahir�*s brother. "i just want my sisters to get better." he says it three times. coughing an exhausted fatouma joins her daughters on their blanket. one family in a nation

still overwhelmed by hunger. andrew harding, bbc news, somalia. world leaders are meeting in bali in indonesia for a summit of the 620 group of nations. the main focus is the stability of the global economy, but there will also be lots of discussion of the war in ukraine. the british prime minister rishi sunak said russia would hear a chorus of global opposition to its actions. and after nearly three years of covid isolation, this summit is also an opportunity for world leaders to meet face to face. our north america editor sarah smith reports. president biden looks eager to meet again with a man he always says he knows well. this is his first face—to—face with president xi as leaders of their nations, but they spent many hours together when they were both vice presidents — hence the relaxed body language and maybe even a cooperative mood, despite relations between their countries being at their worst for decades. there is much to discuss, from economy, trade and climate

change, to human rights, the war in ukraine and of course taiwan. no wonder the meeting lasted for over three hours. as leaders of our two nations, we share responsibility in my view to show that china and the united states can manage our differences, prevent competition from becoming anything anywhere near conflict. they agreed — nuclear weapons must not be used or even threatened by russia in ukraine. the biggest problem is taiwan. president xi called it the first red line america must not cross. the recent visit by the senior us politician, nancy pelosi, to the democratic self—governing island enraged beijing. china responded with military exercises around the island. president biden today warned his chinese counterpart against trying to change the island's status, but also told him the us has not changed its policy which acknowledges taiwan is part of china.

after today's meeting, he said he does not think there will be an imminent attempt to invade taiwan. we're going to compete vigorously, but i'm not looking for conflict, i'm looking to manage this competition responsibly. and i want to make sure, make sure that every country abides by the international rules of the road. i absolutely believe there need not be a new cold war. there was never an expectation of any binding deals coming out of today's meeting. instead, it was an attempt to lower the temperature, with each country setting out what it will not tolerate from the other in the hope of preventing disagreement turning into conflict and to try to avoid a new cold war. sarah smith, bbc news. let's go to washington now and speak tojosh lipsky. he's the senior director of the atlantic council's geoeconomics centre. thank you so much forjoining us. so comparatively positive

words and motions coming out of that meeting between president biden and xijinping. do that meeting between president biden and xi jinping. do we expect that to set the tone for the meeting, do you think? i think so. as the best we could have hoped for coming out of that meeting and the expectations were understandably low going in. but you saw causal relationship as they saw each other for the first time with president biden as president and then a three—hour meeting stop and that was substantive. they cover taiwan, they covered human rights abuses, they cover trade issues. and we didn't expect any major agreements coming out of it, but it was a positive start to the 620 and the indonesians in the host country were especially pleased to see it because vladimir putin and his shadow are really dominated the lead up to this 620 and so to start on the somewhat positive constructive note with the leaders of the two largest economies meeting face—to—face was exactly what

the 620 is there to do. we will see if it can continue today as all the leaders meet. with re . ards all the leaders meet. with regards to the _ all the leaders meet. with regards to the 620 itself, | all the leaders meet. with i regards to the 620 itself, in an era of currency, of billionaires worth more than countries, future emerging economies who aren't members of the 620, is it still fit for purpose?— the 620, is it still fit for --urose? ~ . v purpose? well, that's the fundamental _ purpose? well, that's the fundamental question - purpose? well, that's the fundamental question of. purpose? well, that's the i fundamental question of this 620, different than any other 620, different than any other 620 that has preceded it. usually you go into a 620 summit anything about what is on the agenda, what do they need to make progress on, and is not that we have a shortage of issues to talk about, inflation, debt relief, but the fundamental question of this 620 is will the 620 continue to exist after this meeting and that's because the war in ukraine has fractured at the g20 ukraine has fractured at the 620 between the countries are sanctioning russia and the countries that are not sanctioning russia. in this 620 needs reform, and needed reform before the war in ukraine, is now. one idea put forward is to expand and rethink the membership of the 620, hasn't changed it was created and 1998 over 1999, changed it was created and 1998 over1999, but changed it was created and 1998 over 1999, but the top 20 economies of they will have

change of that period of time as i have call for countries like poland and thailand to join, but the point is, to succeed in the long—term, only 620 should, because it is an important it does need to adapt. important it does need to ada t. important it does need to ada t, ., important it does need to adat. ., , , important it does need to adat. ., , ., ., adapt. so on the basis of what ou 'ust adapt. so on the basis of what you just said. _ adapt. so on the basis of what you just said, what _ adapt. so on the basis of what you just said, what will- adapt. so on the basis of what you just said, what will we - you just said, what will we consider to be a successful summit in 2022? so consider to be a successful summit in 2022?— consider to be a successful summit in 2022? so two things. you know. _ summit in 2022? so two things. you know, first _ summit in 2022? so two things. you know, first of _ summit in 2022? so two things. you know, first of all _ summit in 2022? so two things. you know, first of all we - summit in 2022? so two things. you know, first of all we can't . you know, first of all we can't expect any unity. not going to get anything that the us and russia and china and all of the countries are going to sign onto, a joint statement like we're used to saying, but you can make progress on the sidelines. just one small example, we saw today an announcement about debt restructuring for chad, this was the first debt restructuring on the 620 was a common framework that has been two years in the making, that is one country, there is more thanis is one country, there is more than is redone, but you might see a few small items like is, at least positive, constructive movement forward, you will see leaders meeting face—to—face with ever many years and i do

think there is something positive to take away from that. so it is incremental steps with the hope that the g20 steps with the hope that the 620 can continue to succeed and thrive when india takes over next year in 2023. but as long as vladimir putin remains in ukraine can never function like it did before.— it did before. josh lipsky “oininu it did before. josh lipsky joining us _ it did before. josh lipsky joining us from - it did before. josh lipsky . joining us from washington, it did before. josh lipsky - joining us from washington, dc. you so much. thank you. the president of ukraine has been to the southern city of kherson, just days after russian troops withdrew from the city. volodymyr zelensky addressed soldiers in the main square saying ukraine is moving, step—by—step, towards liberating all occupied territories. losing kherson is a major strategic blow for russia, though moscow insists it remains russian territory. we are going forward. we are ready for peace. but lps for our country is all of our country, all of our territory. we respect the law and respect

sovereignty of all the countries, but now we're speaking our country. let's get some of the day's other news. the director of the cia has met the head of russia's foreign intelligence service in the turkish capital ankara. the white house said william burns spoke about the consequences of using nuclear weapons, and the risk of escalation — adding that it was not conducting negotiations of any kind, and not discussing a settlement to end the war in ukraine. kurdish groups in turkey and syria have denied being behind a bomb attack that killed six people in istanbul on sunday. two organisations, the pkk and the sdf, said they didn't play any role in the explosion, which happened on a busy shopping street. the turkish authorities say kurdish militants were to blame. police have arrested the woman suspected of planting a bomb. the uk will pay france £8 million more a year under a revised deal to try to stop people crossing the english channel in small boats. the money will pay for increased surveillance of french beaches, while uk police officers will also be able to observe patrols within france.

britain's stock market has lost its position as europe's most—valued with france taking the top spot according the new data. a weak pound, fears of recession in the uk and surging sales at french luxury goods makers are thought to be behind the shift. the american comedianjay leno has said he's "ok" after being burned in a fire. the 72—year—old was taken to hospital on sunday after one of his cars burst into flames inside his garage. the former talk show host said he'd suffered serious burns but was now in stable condition. stay with us on bbc news. still to come: the bbc celebrates the 100th anniversary of its first official radio broadcast. before this last drought,

an international charity says the drought in somalia has led to the biggest movement of refugees in more than a decade, and 500,000 children under five are now at risk of death by the middle of next year. world leaders are gathering in bali fora summit of the 620 group of nations. high on the agenda — the energy crisis, the war in ukraine and the stability of the global economy. the global population is projected to hit a new all—time high on tuesday, reaching the landmark figure of 8 billion people according to the united nations. the world's population has doubled in less than 50 years and is set to keep rising. 0ur medical editor fergus walsh has been examining the figures and what it means for us all. 0ur planet has never held so many people as the era of huge population growth continues. back in 1800, there were around 1 billion people on earth, and it took over a century for that to double. then it really took off in the 20th century,

reaching 3 billion in 1960 and putting on nearly a billion each decade after that. it reached 7 billion in 2011. we're now set to hit 8 billion people on the planet. so what about the future? the un projects they'll be 9 billion people by around 2037 —— there'll be 9 billion people by around 2037 and 10 billion by 2058. 6lobal population could peak at around 10.4 billion in the 2080s, and then plateau before declining in the next century. the united nations says more than half the projected population increase to 2050 will be in just eight countries, half of them are in sub saharan africa. indeed, the total population of this entire region is set to almost double to 2 billion by 2050. remember, it includes some of the world's least developed countries, many already experiencing food insecurity. india and china are the world's

most populous countries. both are home to more than 1.4 billion people, but india will overtake china next year. china's population, along with scores of other countries, is set to fall sharply later this century. now, that's because global fertility is declining dramatically. back in 1950, women gave birth, on average, to five children. that has since more than halved to 2.3 births and it's set to fall even further. but there are so many people of child—bearing age now, that explains why the global population will keep rising for much of this century. another reason is we're living longer. average global life expectancy reached almost 73 years in 2019, up almost nine years since 1990. covid actually pushed it down by nearly two years, but it's projected to keep rising.

the world's population is also ageing. about one in ten people on the planet is now 65 or older. by 2050, it will be almost one in six. so that will put a greater burden on the young. 0ur growing population also puts increasing pressure on resources — food, water, energy, as well as infrastructure. huge issues for society with lasting implications for our planet. jeff bezos, the billionaire founder of amazon, has previously been criticised for not giving more of his money to charity. now, in an interview for cnn, he's announced he's going to give a majority of his fortune away. but he says he's finding it difficult to choose where the money should go. 0ur north america technology reporterjames clayton has more. jeff bezos is one of the richest people in the world. he's worth more than £100 billion. and yet, mr bezos has been criticised for his lack of charitable focus. his detractors say

he's more interested in burning his money on going to space, which he did last year, than saving the planet that he actually lives on. famed for turning his idea for an online book store into a tech giant, some have argued that the amazon founder has so much money, he could buy much of the amazon rainforest to protect it. now, his first statement saying he'll give away most of his fortune. do you plan to give away the majority of your wealth in your lifetime? yeah, i do, and the hard part is figuring out how to do it in a levered way. it's not easy. building amazon was not easy. it took a lot of hard work, a bunch of very smart team—mates. and i'm finding, and i think lauren's finding the same thing, that philanthropy is very similar — it's not easy, it's really hard. mr bezos has a very strange, very big tech problem, in that he has so much money, he doesn't quite know what to do with it. he says he wants to focus on climate change, homelessness and food insecurity,

and with, frankly, mind—boggling wealth, he could have a huge impact. he said he'll give $100 million to dolly parton's charity, which focuses in part on child literacy. but that could be the tip of the iceberg. some of the poorest, their toilet may look like this — a pit latrine. bill gates has given away a fortune to charitable pursuits. jeff bezos could afford even larger donations. however, like many other silicon valley billionaires, he's been criticised for paying relatively little tax on his huge fortune. and withjeff bezos still an influential figure in amazon, some say he should be doing more to make the company he derives his money from greener too. james clayton, bbc news, california. the bbc is celebrating the 100th anniversary of its first official broadcast, a news bulletin from london. 0ur correspondent david sillito reports. hello.

2l0 calling, 2l0 calling. november 1a, 1922, and the beginning of the bbc. 2l0 was the call sign of the bbc station in london. and 100 years on, the six o'clock radio news has been marking how it all began. bell tolls this bulletin marks the moment 100 years ago that the bbc began broadcasting. back in 1922, the newsreader at 6pm was arthur burrows. arthur burrows at this point is the first voice of the bbc. he's almost had the idea of broadcasting a few years earlier as well, and within a month, he'll be director of programmes at the bbc and one of ourfirst children's presenters. yes, arthur was also �*uncle arthur', children's entertainer. it wasn't a large organisation on day one. how many staff at the beginning, in november 1922? november 1922, the bbc has a staff of zero. there are no employees. there are no official staff? there are no official staff.

arthur burrows does that first broadcast essentially in his spare time. was itjust london in november 1922? no, london was day one, and then day two was birmingham and manchester, and that's where you get musical concerts, children's programmes come in there, the general election results as well, all mixed in together. singing and the bbc has only now been discovering how many of its pioneering programmes came from manchester and birmingham. 0verto you, birmingham. it's adding details to its online radio times history about satire, concerts. and this is puppy from the children's programme from glasgow. but it began with the news and it was nerve—racking. arthur burrows later wrote he could think of no more exacting a test of physical fitness than the reading of a news bulletin. david sillito, bbc news. can you solve a rubik's cube? george scholey, a so—called �*speed—cubing champion' has set a new world record

by solving the puzzle 6,931 times in the space of 2a hours. his average speed per cube is 12 seconds, but he can do it in nearly half that time. here's george on bbc news earlier. watch and marvel. just remarkable. i will blame the fact that i am hopelessly colourblind rather than incapable of doing it myself. a reminder of our main news — a summit of the g20 group of nations has begun in bali in indonesia with the host, presidentjoko widodo, warning that the world is facing crisis after crisis. in his opening address, he said the war in ukraine was impacting food, energy and financial security, with developing countries worst hit. he appealed for an end to the war, saying it would be difficult for the world to move forward until it was over.

plenty forward until it was over. more details on our website. you can reach me on twitter — i'm @garethbarlow. thanks for watching. hello there. 0n the whole, it was a relatively quiet start to our working week, but a change is on the way, and you can see that as we close out the day in cornwall on monday with this blanket of cloud closing the curtains across the south—west and, yes, there's a weather front that's bringing some wet and windy weather. you can see the extent of the cloud on the satellite picture, actually, and it's this frontal system tied in to an area of low pressure, which will continue to move further north and east. so, for the next few hours, be prepared for some heavy rain, but more importantly, some gale—force gusts of winds — gusts in excess of 50—60mph, as that rain continues to push its way

steadily north and east. so, first thing in the morning, the rain heaviest perhaps across parts of dorset, moving up through hampshire. then that's going to drift its way steadily northwards through the east wales, into the midlands, to north—west england, and eventually, it'll push its way steadily north and east. there will be quite a clearance behind, some sunshine and a scattering of sharp, blustery showers in the far south—west. the winds will be a feature, but the strongest gusts still with that rain, so gusts in excess of 55mph plus in the northern isles as that rain pushes its way steadily northwards. temperatures, 11 to 1a degrees, about where they should be for the time of year, but obviously, it'll feel cooler with the cloud, the wind and the rain. so, the rain pushes its way steadily north, we'll see a cluster of showers through wednesday night across west and south—facing coasts, but where we do have some clearer skies, we'll see low single figures, so it could be a bit of a chilly start to our wednesday morning. 0n the whole, wednesday is a chance to get a little bit of a breather in. there will be some showers across the south and the west first thing, slowly improving

into the afternoon before the next system moves in, more wet and windy weather still yet to come. a cooler day, top temperatures between 10 and 13 celsius. now, it looks likely that we'll see another spell of wet and windy weather through the latter stages of wednesday into thursday before a little ridge of high pressure fills in behind — that's worth bearing in mind. so, all in all, as we close out this week, it looks likely that we will see another unsettled day on thursday, friday, the best of the dry weather, and it's probably a good opportunity to make the most of it. the weekend looks wet and windy once again.

this is bbc news. the headlines: an international charity says the devastating drought in somalia has led to the biggest movement of refugees into kenya, in more than a decade. save the children said hundreds of people were arriving every day. nearly 70,000 more are expected to arrive by april next year, as somalia edges closer to famine. world leaders are gathering in bali in indonesia for a summit of the g20 group of nations. high on the agenda — the stability of the global economy, the energy crisis and how to address the ongoing war in ukraine. president putin is not attending, but president zelensky will address the gathering by video link. president biden has played down fears of a new cold war with china after holding his first talks with xi jinping. the white house said the us would compete vigorously
