high—level arrivals in delhi: joe biden meets the indian prime minister modi ahead of this weekend's 620 summit. the un calls for radical changes to slow global warming as extreme weather events hit areas from greece to hong kong. and jazz is enjoying a resurgence in the uk: we'll look at why. hello, i'm carl nasman. welcome to the programme. leaders from many of the world's largest economies are gathering in india for the 620 summit that's getting underway. while the theme for the meeting is sustainable development, the leaders are expected to tackle an array of issues

over the weekend in india's capital delhi, including global food security, climate change, trade and the war in ukraine. india's prime minister narendra modi would like the summit to promote his country as a major global power but russia's war in ukraine may be standing in his way. india is looking to put aside disagreements over ukraine, hoping it won't derail concerns of the global south and developing countries. in one of his first official duties as host, mr modi met with us presidentjoe biden for a 52—minute meeting. the two leaders discussed india's recent moon landing and investments in indian technology. they released a joint promise to deepen their relationship saying it was, quote, "based on trust and mutual "understanding." our south asia correspondent yogita limaye is in delhi and has more. ahead of the 620 summit, we saw presidentjoe biden meeting with indian prime minister narendra modi and soon after

that meeting, the trade disputes between the two countries was resolved. both countries was resolved. both countries saying we are really just furthering the discussions that we've had where modi went on a state visit to the us in june. of course, during the 620 summit, one of the big issues on the agenda and what is going to overshadow the summit, of course, is the war in ukraine. india will be hoping that irrespective of the deep differences between countries on that, irrespective of the fact that russian president vladimir putin is not attending, chinese president xi jinping is not attending, that there will be some joint form of wording that will be agreed to that can be released at the end of the summit. and i think what india is also hoping for is perhaps the focus can be on other issues like climate change, like globalframework change, like global framework for cryptocurrencies. change, like globalframework for cryptocurrencies. india has done quite successfully is that it is done what is an annual summit and it is done what is an annual summitand the it is done what is an annual summit and the presidency that they got because of rotation into a mega event to showcase its strength to the world and

trying to tell the world that they can be the voice of the developing world. prime minister narendra modi advocating very strongly for the african union to be included in the 620 so that this grouping can be more representative and fare. as far as the domestic audience in india is concerned, we are going into an election year here and i think what his government and party are trying to say to voters is all of these important leaders coming to india, the country's globally is growing and it is our government that has done that. of course, what we've seenin that. of course, what we've seen in delhi is the spectacular venue but what we have also seen is the impoverished areas, slums being destroyed or hidden from view, the disparity that exists in india's city being hidden from view, and people are saying what is the summit actually really going to get from us on the ground? 0nce really going to get from us on the ground? once these meetings are over? have also heard prime minister modi repeatedly referred to india as the mother of democracy and there are many

people who are asking questions about that phrasing because what we are seeing in india is increasing restrictions on press freedom. uk prime minister rishi sunak was also among the global leaders who arrived to delhi on friday. mr sunak made history, becoming the first prime minister of indian heritage to visit the country. his goal? a trade deal between india and the uk. mr sunak says he is hopeful but that it will take time. well, both modi and i are keen to see an ambitious trade deal between our two countries on both of us think there is a good deal to be done but trade deals always take time, they need to work for both countries and although we have made enormous progress, there is still hard work to go and that's what we need to keep going through. the 620 is not the forum for those discussions, of course. i will touch on that with my minister modi. —— prime minister. notably absent from this weekend's gathering,

china's president xijinping and russian president vladimir putin, who both sent their respective foreign ministers to attend in their place. it's mr xi's first time skipping the gathering, with no explanation offered. a little refresher now on what exactly the 620 is. the group of 20 is a bloc of the world's 20 largest economies that was formed in 1999 in response to the 1997 asian financial crisis, when thailand devalued its currency plunging much of east asia into a deep recession. originally, the 620 was a forum for the finance ministers and central bank governors of member nations to meet to discuss global economic and financial issues. by 2008, heads of state and government began meeting to address the 2007 financial crisis. and in 2009, the 620 summit became an annual forum focused on not only economic issues, but sustainable development, health, environment, and anti—corruption. the 620 itself is comprised of 19 countries and the european union. and together, its member nations account for

an estimated 86% of the world's gross domestic product and two—thirds of its population. the theme of this year's 620 summit is one earth, one family, 0ne future and against that backdrop, the un has warned that the world is falling behind in its fight to curb global warming. in a new report, the un says countries are making progress, but not nearly enough. it calls for radical changes in the way we work, eat, travel and consume energy to combat rising temperatures. but the report also suggests hope is not yet lost, asjustin rowlatt reports. wild raged through southern europe this summer, made more intense by heatwaves that would have been virtually impossible without climate change, according to scientists, today's un report says it is

not all bad news on global warming. virtually all of the nations of the world agree on the urgent need to tackle the problem, says the un, and they are already taking some action. the problem is itjust isn't anywhere near enough. i the problem is itjust isn't anywhere near enough. i am in a lace of anywhere near enough. i am in a place of hepe — anywhere near enough. i am in a place of hope and _ anywhere near enough. i am in a place of hope and despair. - place of hope and despair. despair because we have warmed the planet already well beyond one degree and we are on track for 1.5 and these are worrying places to be in. i also have hope because we see how countries are putting together real plans to change their entire economies. but progress is bein: entire economies. but progress is being made. _ entire economies. but progress is being made. just _ entire economies. but progress is being made. just look - entire economies. but progress is being made. just look at - is being made. just look at this global thermometer. back in 2010, un reckoned the world was on track a temperature increase of 4.8 degrees celsius. it warned that would be catastrophic. 2015, countries had promised cuts that brought that down to 3.2 celsius. by the end of the

climate conference in glasgow in 2021, it was down to 2.7 celsius. and the un now reckons we are headed towards a temperature rise of around 2.6 celsius. but that is still way over the 1.5 celsius target the world has agreed. this over the 1.5 celsius target the world has agreed.— over the 1.5 celsius target the world has agreed. this is about ace and world has agreed. this is about pace and it's — world has agreed. this is about pace and it's about _ world has agreed. this is about pace and it's about recognising| pace and it's about recognising that we need to speed things up, whether that's in the uk or, indeed, across the world, and that's why it comes back down to the appetite of world leaders to recognise the urgency of the situation and be willing to act. but urgency of the situation and be willing to act.— willing to act. but is the appetite _ willing to act. but is the appetite there? - willing to act. but is the appetite there? a - willing to act. but is the appetite there? a rapid | willing to act. but is the l appetite there? a rapid to renewable energy will be indispensable, says the un. the uk has made world leading progress on that transition but today, it appeared to falter. there were no bids for new offshore wind projects because my said energy companies, the cash on offerfrom my said energy companies, the cash on offer from the governmentjust didn't make it worthwhile. raising questions about the uk's commitment to

climate action. justin rowlatt, bbc news. with global temperatures rising, more countries are witnessing extreme weather conditions. 6reece witnessed its heaviest rainfall in almost 100 years this week. some areas were hit with a year's worth of rain in under three days. the bbc�*s sofia bettiza has more. a trail of devastation across central 6reece. this region was hit by the heaviest rainfall the country has seen since records began. entire villages have been engulfed by water. and a massive rescue operation is under way to evacuate hundreds of people trapped for days. many without food or drinking water. this woman has lived in her house for more than 30 years. and is that the one in the yellow tent? yes. it's completely submerged in water. yes.

translation: my home is completely destroyed. j i have nothing left. all i have is my work, this house and my children. and now our home is gone. climate change is causing more extreme weather. recently, 6reece faced the worst summer of wildfires on record. translation: it's a tragedy. we will suffer for a very long time. the damage to our homes is irreparable. a lifetime's work gone in a couple of hours. the damage to infrastructure is enormous. many roads are impassable and bridges destroyed, adding to the problems faced by emergency workers. many people here are furious at the greek government. they accuse ministers of using climate change as an excuse for poor building projects. take this bridge, for example. it collapsed three years ago because of a cyclone, so it was rebuilt. and now, it's completely

destroyed again. for many 6reeks, this is a symbol of government failure. the army has been brought in to distribute food. this storm has destroyed crops on some of 6reece's richest land. nearly a quarter of this year's agricultural production has been lost. tourism will suffer, too. another blow to 6reece's already fragile economy. dog barks. tonight, the search goes on for those still missing. the long—term damage caused by storm daniel will take many years to overcome. sofia bettiza, bbc news, larissa. a strong 6.8 magnitude earthquake has hit central morocco, sending people rushing into the streets. the epicentre was about 70km — or more than 44 miles — south—west of marrakesh, according to the us geological survey.

numerous buildings have been damaged and local media is reporting that five people have died. the bbc has not confirmed those fatalities. we'll have more on this story as it develops. here in the us, former president donald trump's white house chief of staff mark meadows has lost an effort to move his criminal case from fulton county, georgia to a federal court. meadows is charged along with 18 others, including trump, in connection with a 2020 election interference probe. this comes hours after a newly unsealed report indicates a special grand jury in the state also recommended charges against senator lindsey graham and two ex—lawmakers among others in the investigation into former president donald trump's efforts to overturn the 2020 election but authorites chose not to pursue those charges. people living in russian—occupied areas of ukraine are being asked to vote in what de—facto authorities are describing as local elections. kyiv and the organisation for security and cooperation in europe have denounced

the polls as illegal. candidates are all either russian or pro—russian and include governors hand—picked by moscow. 0ur diplomatic correspondent paul adams is in kyiv with more. this is the second time in a year, ukrainians living under russian occupation in the south and east of ukraine have been asked, invited, encouraged, maybe even cajoled to go to the polls. last it was a referendum for those areas joining russia, last it was a referendum for those areasjoining russia, a referendum condemned around the world is a sham and this year, it is about local and municipal elections, or part of russia saying that these areas are becoming more and more and integral part of the russian state. ukrainian officials say that they have ample evidence of people being encouraged

through text messages and other ways to vote for vladimir putin's ruling party. there are reports of people being expected to vote at mobile polling stations, where sometimes armed men are present. it does not look like anything remotely resembling a free and fair election and once again, it has been condemned both abroad and here in kyiv. the ukrainian authorities have not taken this lying down. they are saying they are compiling lists of any ukrainians who are participating in this election process and they have also been in the last couple of weeks ago couple of explosions at buildings that are not where the election was being prepared. a little sign of ukraine taking steps to try and influence events on the ground outside of areas under its control. paul adams reporting there. well earlier this week, us secretary of state antony blinken visited ukraine and announced a further $1 billion of military aid.

also this week, a russian missile struck the eastern city of donetsk, killing at least 17 civilians in a midday attack. earlier my colleague caitriona perry spoke with kurt volker — he served as us ambassador to nato and then as washington's special representative on ukraine negotations. kurt volker, thank you forjoining us. you are in ukraine this week. with the recent attack in a market in the middle of the afternoon by russia, is there a sense on the ground that this conflict is shifting? mmm, i wouldn't say that. these attacks by russia, which killed civilians and are fairly indiscriminate happen with some regularity. it's tragic, it's unfortunate, people are angry about it, they despair about it, but at the same time this is typical. so ukrainians have built up a tremendous amount of resilience and resolve, and they realise that the only way to guarantee peace and security in ukraine again

is for russian forces to be defeated. and so that is what they are focused on. and as you are in the country now, what you've seen of the counteroffensive, are those measures deterring russia at all? no, quite the contrary. i think that because russia is unable to have any significant military gains on the front line, they have resorted to indiscriminate attacks on civilian areas, just to create terror in the population and to show that they are still there and they can still create havoc. this doesn't change ukraine's attitude of resolve. but russia is willing to engage in those tactics because they don't have many other choices. that again underscores why it's so important for ukraine to actually defeat the russian forces to make these attacks stop. what do they need to do that? we saw secretary of state antony blinken this week

pledging even more, another billion from the us. what does ukraine need? i very glad that secretary of state blinken was in ukraine this week. i think that he will have a lot of work to do when he gets back to washington to convince others in the administration, and especially congress, that ukraine needs more assistance and we should be providing it. there's a request from the administration to the congress for $24 billion of additional military assistance. that is not enough to cover all of next year. it's only enough to cover the rest of this year. and we don't want to see multiple votes over this over time, and it could become more a domestic political issue. he needs to make the case for aid and frankly i think it needs to be a bigger case. what is the case, how is he going to make it? honestly, i think the most important thing for anyone to say is that ukraine's victory over russia is an american interest. it's a national security interest. because russia has now unveiled itself.

it is deliberately engaging in genocide, it is an imperial conquest to retake territories of the russian empire, and russia feels it has a right to them. this is exactly what caused world war ii, when hitler in germany and imperialjapan were doing the same thing. we run a risk that if this is not stopped, this will escalate. and so we have to actually help ukraine to stop the war in ukraine. and i hope that secretary blinken is able to make that case in the united states effectively. and frankly i also hope that president biden goes out and explains to the american people why this is an american interest, not just help for another country. on that point of escalation, notwithstanding international sanctions, international organisations have really not been able to deter president putin and push sufficiently

back that russian offensive. you've been writing, encouraging nato to declare red lines — what should they be? first off you mentioned deterrence. deterrence is preventing someone attacking because they know the consequences of doing so would be too great. we failed at that — russia attacked ukraine because it calculated that there would not be such significant consequences. maybe the withdrawal from afghanistan was part of that, maybe our experience in iraq and syria were part of that. maybe it was just vladimir putin's intent to build the empire that guided him on this path. whatever reason, we did not deter russia. now what we need to do is ensure that russian forces are defeated so that we can reestablish deterrence so that they know it is not worth it to do it again. what are the things that are needed? there are several things. first off i think air cover, air superiority, we're talking f—16s but that's going

to be a long time away. other things can also be done to help ukrainians with establishing air dominance in ukraine. second, we need to help ukraine open the sea lines. the port of 0desa is still blocked up and not able to provide the safe venue for imports and exports that ukraine as a country needs. so helping ukraine reestablish freedom of navigation through the black sea would be a significant thing. finally, air defences. ukraine is suffering from russian drone and missile attacks against civilian population centres almost every night. they do a good job of shooting down most of these but we can help them do more. we should begin to play a more direct role in ukraine's air defence. so if we look at the g20 summit taking place in india at the moment, russia and china are not there. is that an opportunity then

based on what you are saying for those leaders of the world's strongest economies to come together to put further pressure on president putin? yes, in a way. i think what we've seen is a pattern of countries in the global south to take a distance from the russian war against ukraine and say "look, it's not our war, it's "not our concern. "we were colonised, we're recovering, "this is your problem." i think they don't appreciate quite enough how much russia's war against ukraine affects the entire globe. farmers in argentina pay higher prices forfuel and that inhibits them from doing things in theirfarming. people in sub—saharan africa are paying far higher prices for basic foodstuffs, which means some people will not have access. people in india are getting cheaper russian gas and oil than they might�*ve otherwise gotten, but paying higher places on other things. and also looking at globalfood markets,

it has a tremendous global disruption. i think that bringing that home to people around the world is important so they see that russia's aggression has to be stopped. 0k, plenty more to talk about but we will leave it there for now. kurt volker, thank you so much forjoining us. turning to music now, and the uk is seeing a bit of a resurgence injazz. on thursday night, the band ezra collective won the prestigious mercury prize. this was the first time a jazz act won the award since it began 3 decades ago. david sillito has been looking into whyjazz is swinging back into fashion. the winner of the mercury prize... exra collective! it would be fair to say that the ezra collective enjoyed this moment — and it was also a chance to say thank you. this moment we are celebrating here is testimony to good special people putting time and effort into young people to play music, do you hear what i am saying?

and this is what he was talking about. meet tomorrow's warriors. jazz is cool. this workshop that nurtured the musicians of ezra is free and packed with a youthful passion forjazz. jazz speaks to my soul and as a way for me to express myself and it allows you to play through your different experiences, if you are going through something, i can speak that through the trumpet in a way that words can't. and for the man in charge over the last 30 years, jazz bassist gary crosby, this is a moment to savour. at first it was, oh my god, it is a benefit for all of us who are interested in playing this wonderful music we call jazz. but the music that is emerging in and around bands like ezra

isn't looking to jazz�*s 40s and 50s heyday. this grew out of a club night in deptford in south—east london, founded by this man here — and for him, the music from the scene represented by ezra is jazz but also something more. this is something different, music you can dance to, music you can socialise to in a world where most of us don't go to jazz clubs and don't go to sit down and listen to music. and very much born out of 21st—century uk? completely. this could only happen in the uk, in britain. i don't think it could happen anywhere else. it is a combination of all of my friends that come from all these different places. and it's also a reminder that music education like this is only possible because of a music charity. to see them recognised by

the industry and by their peers and to see them elevate all of this music that is happening that they have been part of was just such a great moment. for ezra and all the people following their footsteps, this really is a moment to enjoy. david sillito, bbc news. and before we go, an update from flushing meadows and the us open — tennis star novak djokovic has beaten the unseeded american ben shelton in straight sets to reach his tenth us open final. he'll now meet either daniil medvedev or the world number one, carlos alcaraz, who play each other in the second semifinal. djokovic sits one win away from a record—equalling 24th grand slam victory. that's all from us for now, i'm carl nasman. i'll be back in 30 minutes with a special look at the g20 summit.

stay with us here on bbc news. hi there. for many, this weekend is going to be hot and humid again, especially for england and wales, with temperatures only slowly coming down across scotland and northern ireland. and as the cooler air starts to invade in there, we're likely to see increasing chance of thundery downpours, some of which could be quite heavy in places. certainly england and wales on sunday. now we've had some cloud drifting up from the south as we move into the early part of saturday, some mist and low cloud around some coasts of south west england and wales. and it's here where we could see some showers or some thunderstorms, same too, across the north and the west of scotland. but elsewhere, it's a dry and a clear night. and again, another very warm and muggy one to start saturday morning with temperatures no lower than around 18 or 19 in one or two spots. so it's a very warm start to saturday, pretty much from the word go. we'll have sunshine around, but well, this weather front will be pushing

into the north west of scotland, bringing thicker cloud breeze, outbreaks of rain, a few showers elsewhere. and there will be some scattered thundery showers developing across england and wales as we see temperatures peak at around 32 or 33 degrees in the south—east. so this could be the hottest day of the heatwave. but these showers and thunderstorms, although well scattered, could be pretty intense if you catch one and there's a chance of some localised flooding as well. but most places will be dry to take us into saturday evening. we could see further clusters of showers and thunderstorms running up from the south. again, it's going to be a warm and a muggy night, especially so for england and wales with temperatures beginning to come down across the north—west. now the great north run on sunday across north—east england looks pretty decent actually, although there will be some rain around. some of it could be thundery. these temperatures will be pretty comfortable for running in, but we could start off with some thundery rain in the morning and then into the afternoon. heavy showers could develop with a bit of sunshine in between. but sunday is another warm and humid one for england and wales, with a scattering of thunderstorms developing into the afternoon. temperatures again up to 30

degrees in the south—east, but you'll notice the low 20s for scotland and northern ireland. so things are turning cooler and the trend as we head into next week is for this cooler, fresher, less humid air to spread southwards across the country. and that'll introduce north—westerly winds and also plenty of showers, particularly in the north and the west. it'll be much cooler by day, much fresher at night, but still some good spells of sunshine across the south.

voice-over: this is bbc news. we'll have the headlines for you at the top of the hour, which is straight after this programme.
