so obviously we're doing something right on the small screen. this is bbc world news today. i'm karin giannnone. our top stories... a dramatic warning ahead of the un climate summit — the signs and impacts of global warming are speeding up. we have been breaking records in main greenhouse gas concentrations, carbon dioxide, which is the most important one... the star treatement for narendra modi in texas — the indian prime minister holds a joint rally with president trump. the british government promises no holidaymakers will be stranded. fears grow the tour operator thomas cook might collapse within hours. and in sport, liverpool maintain their searing pace at the top of the premier league, beating chelsea 2—1.

hello and welcome to world news today. ahead of the un's climate conference on monday, scientists have warned the impact of climate change is already hitting harder and sooner than expected. a report compiled by the world meterological organisation says levels of greenhouse gases in the atmosphere are reaching new highs. and the world is heading towards three degrees of warming by the end of the century. i've been speaking to the head of the organisation, who told me things are looking grim. unfortunately, we have been the messengers of bad news. global emissions have grown by 2.1% and this was the case in 2017 and we have been breaking records in main greenhouse gas concentrations, carbon dioxide, which is the most important one and

also methane and nitrous oxide. those are all striking. and we have been breaking records in that system. we have seen this warming continue, lastjuly was the warmest single month since the 18505. and last 5ingle month since the 18505. and la5tjune 5ingle month since the 18505. and last june was the 5ingle month since the 18505. and la5tjune was the warmestjune on record. you describe this is bad news. i wonder if the extent of the increa5e news. i wonder if the extent of the increase has surprised you and outstripped productions? of course, this bad news is we signed the paris agreement in 2015 and there was a plateau in emission growth. but in the past two years we have seen this previous emi55ion growth continue.

and reaching the levels of the paris agreement... that will not happen if we don't change our emissions behaviour. what prospect you think of that message coming through and getting through, particularly on the eve of the climate summit in new york, which you have released this report in advance of? the reason we organised this summit wa5 in advance of? the reason we organised this summit was he would like to see the emission levels globally rai5ed like to see the emission levels globally raised and awareness of the5e globally raised and awareness of these facts will be the basis of the discussions tomorrow. at this summit, this is supposed to serve as raising the ambition levels of climate mitigation and we will have

a climate meeting in santiago in december this year. and most likely the uk will host the next climate meeting in 2020. and then we will agree how to raise the ambition levels of the paris implementations. the head of the world meterological 0rgani5ation talking to me earlier. and you can get the latest science and analysis ahead of the un climate conference on our website. go to bbc.com/news for all that. iran's president has said the presence of foreign forces in the gulf is a threat to regional 5ecurity. it's the latest ratcheting up of tensions between iran and saudi arabia following the attack on saudi oil sites — which iran denies carrying out. ha55an rouhani's comments came during a military parade in teheran. the united states is sending more troops to its ally, saudi arabia. the iranian president said foreign forces had always brought "pain and misery".

translation: at this sensitive and important historical moment, we announced to our neighbours that we extend the hand of friendship and brotherhood to them. we are even ready to ignore their past mistakes in this region. we announced to the world that the presence of foreign forces can be problematic and dangerous for the region. for international waterways, maritime 5ecurity, oil and energy security. but our path and our way is creating unity and coordination with the region's countries. jon alterman joins me from bethesda, just north of washington dc. he's the director of the middle east program at the centre for strategic and international studies. he also used to work in the us state department. welcome. what do you make of what we have heard today from president rouhani? did anything surprise you? not at all, you have been hearing

from iran that the us presence in the gulf makes everybody le55 from iran that the us presence in the gulf makes everybody less secure but all of iran's neighbours are desperate for the us to be present because they think iran makes the regent le55 because they think iran makes the regent less secure. there is a hope we can get to a better place but this week i think everybody is upping the us will stick in rather than pull out. what difference to the overall situation is the increa5e the overall situation is the increase in us troops to saudi arabia? the one announced earlier? they are very targeted for the very specific situation. it was 5urpri5ing specific situation. it was surprising that these cruise mi55ile5 surprising that these cruise missiles and drones were easily able to completely penetrate saudi defences. it is not like the saudis and neighbours have taken expensive 5te p5 to and neighbours have taken expensive steps to protect their oil infrastructure. we don't have a lot of evidence that i am aware of that any of those defensive measures were able to identify early or take down

any of these drones and cruise mi55ile5. they are generally designed for ballistic missiles which have a very high arc and they go which have a very high arc and they 9° up which have a very high arc and they go up and you can see them, they don't seem to have given much warning about these attacks. and the damage to infrastructure is really significant. i wonder if saudi arabia may have been hoping that the us response would have been 5tronger and more dramatic? i am not sure exactly what they were hoping for because if there is a ratcheting up of tensions, the saudis will take much more of a hit than the americans. what we have seen with the saudis being reluctant to this directly to iran, i think is an effort to not only build a little time but also to get more of the world on board. one of the interesting things over the next several weeks is whether china, a big buyer of oilfrom saudi arabia and a big investor in saudi arabia,

whether china can move to be a little more critical of iran and have more of a solution to the problem of iran and its proxies posing what its neighbours perceived to bea posing what its neighbours perceived to be a threat. what about the new gulf peace initiative that mr rouhani has been talking about? saying that would be presented at the united nations in coming days? donald trump reiterating he would like to meet president rouhani on the sidelines of the general assembly but that will not happen?” don't think it will happen. my guess is that in the winter some time we have the possibility after things get a little bit worse that the world will come together and they will try to push the united states and the iranians into some sort of negotiation to ratchet things down. the iranians are in a very conscious effort to try to create a crisis without creating a war to improve

their bargaining position because they are afraid that once they get into a negotiation with a much stronger power like the united states, they will have to give things up. so i get things before they get into the room? because there is this disparity in power. this week is not a week anything will be resolved, we are still gathering evidence and i think there isa gathering evidence and i think there is a very strong case against iranian involvement or suggesting iranian involvement or suggesting iranian involvement or suggesting iranian involvement and they will be playing for time to see how far they can move this into something that gets out of their deeper problem, which is isolated from the world, especially with the us being hostile to them. thank you very much indeed for joining to them. thank you very much indeed forjoining us. president trump and the indian prime minister, narendra modi, have been holding a joint rally in houston, texas. tens of thousands of indian—americans attended the so—called ‘howdy modi' rally. organisers have described it as the largest—ever reception for a foreign leader in the us, aside from the pope. mr modi praised president trump

as a friend of india. mr president... you have introduced me to your family mr president... you have introduced me to yourfamily in mr president... you have introduced me to your family in 2017. and today... i have the honour to introduce you to my family! cheering and applause president trump, in turn, praised the indian american community. i have also come to express my profound gratitude to the nearly 4 million amazing indian americans across our million amazing indian americans across oui’ country. applause. you enrich our culture. you uphold oui’ you enrich our culture. you uphold our values. you uplift our communities and you are truly proud

to be american and we are proud to have you as americans. cheering and applause we thank you, we love you and i want you to know that my administration is fighting for you each and every day. let's take a look at some of the other stories making the news... israel's president has called on the two main rivals in last week's election to come together to form what he called a "stable coalition". reuven rivlin held talks on sunday with representatives from prime minister benjamin netanyahu's likud party and benny gantz‘s blue and white, which now has the backing of the arab list group. there have been angry scenes in hong kong after pro—democracy activists held another demonstration — protesting against what they see as china's growing interference. police fired teargas following a stand—off at a shopping centre in sha tin. tens of thousands of people have marched in slovakia to demand a ban on abortions.

organisers estimate 50,000 people turned out in the capital, bratislava, with the slovakian parliament set to debate draft legislation which aims to restrict terminations later this month. the country currently allows abortions up to 12 weeks of pregnancy. the british government has pledged that holidaymakers will not be left stranded if the world's oldesr tour operator, thomas cook, goes into administration, but dampened hopes of a bailout. the compa ny‘s shareholders have been meeting with creditors today in a bid to find almost $250 million in extra funds. around 150,000 holidaymakers around the world could be stranded if the company collapses. our europe correspondent, gavin lee, has been meeting some of the thomas cook holidaymakers who've just flown in to palma

we have witnessed the last flag of the day. we can catch a quick word with people. quick word with the bbc, you have come from glasgow today? you could be on the last flight today? you could be on the last flight of the day? you could be on the last flight of the day, potentially, who knows, with the company, how are you feeling given that thomas cook is in a pretty precarious situation? yeah, it is kind of worrying, but there is nothing we can do about it. how has it affected your holiday so far? i mean, you'vejust got here. we just have to take it like it goes. when are you due back? next sunday, a week. will you be looking at your phones, looking at the news, orjust forgetting about it and have a holiday? we'll try to forget about it and just have a holiday, see how it goes. yeah? have you been with thomas cook packages before? no, it's our first time so... well, have a great, relatively stress—free holiday, you can say very little at the moment. a nice smile and business

as usual, thank you! great stuff. well, thomas cook staff have been told that they can't say very much to us, but i have spoken off camera, and there are a few that are worried that if suddenly this company collapses and their jobs ultimately end, people who live here say they'll have to look for something else. there are those who are based in the uk that have been saying to me privately, what do we do, asking us for information. and what we're being told from the company here at the moment is their advice to everybody coming here on the last flight of the day, who knows, possibly the last flight, unless they are rescued, this is the situation at the moment. stay with us on bbc world news. still to come... it's world car—free day. hundreds of cities kick cars to the curb. benjohnson, the ben johnson, the fastest man benjohnson, the fastest man on earth, is flying home to canada in disgrace. all athletes should be clean going into the games and this happened. it is a simple fact that this morning these people were in

their homes and tonight those homes have been burnt down by serbian soldiers and police. all the taliban positions along here have been strengthened, presumably encase the americans invaded. it is no use having a secret service which cannot preserve its own secrets against the world. so the british government has no option but to continue this action, even after any adverse judgment in australia. concord have crossed the atlantic faster than any plane before. breaking the record by six minutes. this is bbc world news today. the latest headlines... scientific data on climate change says the signs and impact of global

heating are speeding up. president trump and the indian prime minister does prime minister have held a joint rally in houston, texas, in front of tens of thousands of indian americans. we turn to our main story — warnings of the ever harder impact of climate change on our planet. switzerland's glaciers have all been shrinking at an accelerated rate in recent years. one of them — the pizol glacier — is set to disappear completely by 2030. scientists have been holding a memorial service for it, as imogen foulkes reports. grieving for a glacier. the old glacier was declared officially dead. a worrying sign, environmentalists believe, of the threat from climate change to the fragile environment. at the end of the ceremony i asked

for god's blessing for courage because only we will not succeed. climate change is important, protection of the environment is extremely important in the challenge to every human being is so great that we need the help of heaven. once a mighty sweep of ice high in the alps, it has lost 90% of its volume in just over a decade. now it is reduced to a few frozen lumps, and soon they will be gone, too. you'll see the ice is broken up into lots of small pieces — that shows what is left of the glacier is very thin and is about to disappear completely. all of switzerland's 1500 glaciers are sinking fast. it is normalfor it is normal for the

it is normalfor the ice to it is normal for the ice to retreat over time. this accelerated decline is due, scientists are convinced, to rising global temperatures. the glaciers are more than just parts of the alpine scenery, they are a vital water source for europe and they provide the glue that holds the mountains together. without them, rock and mudslides will become more frequent. and research by swiss scientists suggests that nearly all of switzerland's glaciers could be gone by the end of the century. james pearce has all the sport. hello and thanks forjoining us. we'll start at the rugby world cup — ireland lived up to their status as the world's top—ranked side with a clinical 27—3 victory against scotland in yokohama.0ur sports correspondent katie gornall was watching in the rain.

last year ireland were seen as the big cup glory at this world cup but the performance coming into this has been like the japanese whether dutch unpredictable. they were under pressure to perform against scotland but they dominated. from start to finish. scoring the first try after five minutes. three in total in the first half. including one from rory best, who retires at the end of the tournament. and there's more to come in the second half. andrew conway showing quick feet to square the fourth try. they have eight days to regroup before they play samoa in kobe and based on this performance, there was lots of work to do. england opened their campaign against tonga and started well with a 35—3 win.

but it wasn't as straightforward as the scoreline suggests. our sports correspondent, andy swiss, is in saporro. this was a comfortable victory for england, getting four tries in the bonus point but it wasn't always a convincing performance. they went into this match as one of the favourites and they were expected to have far too much for tonga but it was not easy for them at first. two tries from manu tuilagi putting england in control at half—time when they led 18—3. in the second half, they led 18—3. in the second half, the extended that lead thanks to further tries from jamie george and look cowan—dickie. but there were lots of handling errors and some nerves perhaps in the england team so nerves perhaps in the england team so they got the result, not perhaps the sort of stylish victory they would have looked for. plenty for them to work on before the next game against the usa on thursday. here are all the scores. italy conceded

an early try to namibia. liverpool retained their 5—point lead at the top of the premier leeague table after a hard fought 2—1win against chelsea at stamford bridge. a trent alexander—arnold free—kick and a header from roberto firmino gave them complete control at the interval, but chelsea had a goal ruled offside by var and then n'golo kante strike set up a nervy finish. we did not play the football we should play, to control the game more. we gave the ball away easily and there were opportunities. and diagonal balls inside. we can defend these situations but we should not force into it. so... kante scores a wonderful goal. it was tight until the end. but we deserve those three

points, it is a difficult place to go. when we do it at always was brilliant. in the other games, ten—man wolves snatched a point at crystal palace with a 95th minute equaliser and ten—man arsenal came from behind to beat aston villa 3—2. west ham beat manchester united 2—0. ferrari's sebastian vettel has won his first grand prix for more than a year. the german was chased home in singapore by teammate charles leclerc, who started on pole, but lost the lead after his pit stop. red bull's max verstappen finished third. championship leader lewis hamilton was in fourth but extended his lead at the top of the championship standings to 65 points, with six races remaining. that's all the sport for now. thank you. sunday is world car—free day — with hundreds of cities banning vehicles from their streets. people in paris have

been taking the opportunity to walk, cycle and scoot on the famous champs elysee, without the presence of cars and buses. the streets of belgian capital brussels were used for a community breakfast. london's financial district was turned into a festival space for families to play and relax. and children were free for once to bring their own sets of wheels onto the roads in hungary's capital, budapest. but while those cities are holding a car—free dayjust once a year, ethiopia does it every month. they've been doing it since the end of last year — and it's proving very popular.

a reminder of our top story... a new un report says the last five years are likely to be the hottest on record. it warns that the world is heading towards three degrees of warming by the end of the century —

much higher than the current goal. thanks for watching bbc world news today. thoughts on the victor come but firstly i have been thinking about september's rainfall. compared to an average month, see how dry it has been across eastern areas and even towards the west, we haven't had 100% as we would expect in an average month up to this point. for that, we have thanked high pressure at times and you can fit one into the jet stream as it meanders right across towards iceland. we are now dipping the other way and into that kink you can fit areas of low pressure and associated fronts. that is how many concluded the week and this is how we start the new week,

new area of low pressure and weather fronts coming in from the atlantic. the last of sundays weather pushing towards the northern isles and then an interlude of finer conditions but that will not last across western areas as the next weather fronts work in from the atlantic. not cold by any means, by day and night temperatures close to the seasonal norm. but as i say, the south—westerly release are laden moisture and they will at times force cloud, wind and rain in their wake. at the start of tuesday, it may well be that we have notjust one little system to affect southern parts but another following close on its heels. they might offer the prospect as you commute on tuesday, particularly across the southern half, of wet and pretty windy weather. we keep a close eye on developments here and it won't be just the south, with time we push heavy rain toward of scotland. i

don't think the rest of scotland or northern ireland will see the worst conditions but that wind will be a feature and some gusts around 45 mph and they might ramp up later across the south—western quarter as the next feature works further towards the east across the southern counties. that could give a windy start to wednesday but thankfully wednesday offers many of us a lull in proceedings. quieter with less wind and more sunshine and hoping to get temperatures into the teams. and a dryer interlude for sure. but it is just a dryer interlude for sure. but it isjust an a dryer interlude for sure. but it is just an interlude a dryer interlude for sure. but it isjust an interlude because a dryer interlude for sure. but it is just an interlude because looking towards the west for the start of thursday, another set of weather fronts and lots of isobars on the chart so another spell of wet and windy weather and initially towards the west but has a day goes on, spreading the prospect of the combination of wet and windy weather from cumbria through northern ireland into the heart of scotland.

the wind lighter than patio towards the south and east but that same weather system eventually drag the prospect of heavy bursts into east anglia and the south—east to start friday. before that frontal system quits the scene and then we go into something with more sunshine and showers to finish the day on friday. temperatures still around about the mid to upper teens. as far ahead as next weekend and we suspect low pressure will still dominate to start off with but look at this suggestion of a little higher pressure trying to build across southern counties. offering perhaps a somewhat dryer interlude and again, thatjet a somewhat dryer interlude and again, that jet stream a somewhat dryer interlude and again, thatjet stream beginning to ta ke again, thatjet stream beginning to take on that characteristic dome but that in its own right could be really short lived. lots going on — ta ke really short lived. lots going on — take care.

this is bbc world news, the headlines: the latest scientific data on climate change says the signs and impacts of global heating are speeding up. the warning comes ahead of the un climate summit in new york. tens of thousands of indian—americans have given a rapturous welcome to the indian prime minister narendra modi and the us president donald trump. the two leaders held a rarejoint rally called howdy modi in houston, texas. the british government says it's ready to fly holiday—makers back to the uk if the troubled tour operator thomas cook goes into administration. it's feared the company's collapse could leave about 150,000 british tourists stranded.

liverpool have maintained their searing pace
