lighter winds, temperatures are set to struggle. this is bbc news with the latest headlines for viewers in the uk and around the world. we're live in glasgow where the cop26 summit — the crucial climate change conference — is getting under way. if we don't act now, the paris agreement will be looked at in the future not as the moment humanity opened its eyes to the problem but the moment we flinched and turned away. us presidentjoe biden said the 620 countries had made tangible progress on climate,

the pandemic and the economy and that the world was ready for american leadership on global issues. what we've seen again here in rome is, i think, the power of america showing up and working with our allies and partners to make progress on issues that matter to all of us. the british government says it's up to france to solve the post—brexit fishing row with the uk, by stepping back from threats over access to its ports. and in bangladesh, our science editor visits a village where rising sea levels are having devastating effects. hello and welcome to glasgow at the start of the long—awaited

climate summit, c0 p26. world leaders, prominent scientists and advisers are ready for 12 days of discussion with one principal aim, to get the world to commit to reduce carbon emissions and avoid a climate catastrophe. already today, we had a glimpse of the problems ahead. the world's richest nations, the g20, met in rome, where leaders were accused of failing to make the necessary commitments. the united nations secretary—general said the time for diplomatic niceties was over, and that the summit in glasgow was the last hope. we start with this report from our political editor laura kuenssberg, on events in rome. a roman sunday stroll. a stylish canine seems the perfect accessory among the ancient alleys. what conflicts, what epic political struggle lives have these streets seen? history around every corner. then spot 15 of the most powerful leaders in the world

taking in the sights. a coin in the famous fountain to guarantee a wish, but it might take more than tradition to stop the uk and france pulling away. others watch on as the two allies are stuck in a spat over fishing rights in channel waters. even borisjohnson wanted italy to inspire progress ahead of the cop climate meeting getting under way at home. if we don't act now, the paris agreement will be looked at in the future not as the moment humanity opened its eyes to the problem but the moment we flinched and turned away. what chance do you think you really have of making progress with 200 countries in glasgow, when you haven't made enough progress with 20 countries here and you don't seem able to sort out the question of a few dozen fishing permits with one of your closest allies, with the french? and we had a wide—ranging and frank discussion,

as you would expect, between long—standing friends and very close allies. downing street even contradicted his claim that both countries had agreed to sort it out. for number 10, it's up to france to back down on its threats to disrupt trade across the channel. the view from his presidential palace is that both countries had agreed to take mysterious sounding measures to resolve the spat. the irritation on both sides of the channel shows no signs of fading, and for borisjohnson, a rumbling row with an important ally like france is not exactly helpfuljust when he is trying to achieve a far wider, grander aim, persuading all his counterparts around the world that slowing down the changes to the climate is a non—negotiable whose time has come. it's not easy, though, some countries don't want to move as fast, the russians questioning the uk ambition for countries to absorb as much carbon as they emit by 2050. why do you believe 2050 is some magic figure?

i want an answer, because you are asking the question, being convinced that 2050 is non—negotiable. but the prime minister has regal backing, and for the heir to the throne, it has been a moment long in the making. now, after i suppose very nearly 50 years of trying to raise awareness of the growing climate and environmental crisis, i am at last sensing a change in attitude. cop26 begins in glasgow tomorrow, quite literally it is the last—chance saloon. as the diplomatic caravan moves from rome's streets to scottish streets, borisjohnson still has a lot of arm twisting to do. do you like roma? i love rome. hope may spring eternal, reality does not. the us presidentjoe biden has spoken about the result of talks

between global leaders at the g20 summit in rome. he said tangible progress has been made on climate change, the pandemic and the global economy, in part due to america's role in the negotiations. i'm proud that g20 endorsed the global minimum tax. this is something the united states has been driving for for over a year, building momentum up to this achievement. this is an incredible win for all of our countries. instead of nations competing each other to attract investments by bottoming out corporate tax rates, this sets a minimum floor of 15% to ensure that giant corporations begin to pay their fair share, no matter where they're headquartered, instead of hiding profits overseas. we've also agreed to establish a fund in the future for countries to draw on to help prevent, if necessary, and responded to the next pandemic, to prepare for the next time around. yesterday, together

with prime ministerjohnson and merkel and president macron, we came together to reiterate our shared belief that diplomacy is the best way to prevent iran from gaining a nuclear weapon, and we discussed how best to encourage iran to resume serious, good—faith negotiations. 0ur correspondent mark lowen has more on the g20 summit�*s final communique. in terms of the climate pledges, the final communique was a bit of a mixed bag, really. 0n the aim of capping global warming ati.5 degrees above preindustrial levels, the g20 leaders said they would pursue efforts to limit global warming to 1.5 degrees and use meaningful and effective actions to do so. but really, beyond that, there were very few concrete actions and concrete ideas as to what they would do in order to keep that dream of 1.5 degrees alive. and that will now probably go

through to the glasgow summit for days of wrangling to try to get to the nitty—gritty of the actions they have to take to move towards the 1.5 degrees cap. in terms of the other thorny issue, which is achieving net—zero carbon emissions by 2050, well, that was the aim of some western leaders, including italy we understand, and quite possibly america, to have 2050 in the final communique, but it doesn't appear because all they talk about is net—zero carbon emissions by or around mid century. and we understand that has been watered down because of opposition to a 2050 date from the big emitters, including china, india, russia, who have talked about 2060 instead of 2050. i think that will disappoint a lot of environmental activists. disappointing alsojoe biden, because he said in that press conference that some people found it disappointing, this g20, "i too find it disappointing

because russia and china did not "show up in terms of their commitments." so that gives you a sense of the disputes and the tough talks there have been at this g20 summits, which will continue at the cop26 glasgow talks over the next 11 or 12 days. tangible progress, said president biden after they communique had been published. that is not how been published. that is not how smaller states who have gathered today at cop26 have seen it. joining me is baroness patricia scotland, secretary—general of the commonwealth. good to see you. you too. i saw uuote good to see you. you too. i saw quote from — good to see you. you too. i saw quote from you _ good to see you. you too. i saw quote from you recently - good to see you. you too. i saw quote from you recently saying | good to see you. you too. i saw- quote from you recently saying that we are right in the eye of the storm but not all in the same boat. i think unfortunately, that's true. if you look at the small states and the commonwealth, we had 5a state but 32

of them are small. so we have 2.5 billion people. but for the small states, they are seeing this as an existential threat. and notjust because it is climatically difficult but because also what is happening with covid—19. they are facing a double whammy. many of them haven't been able to get the vaccines, their industries are therefore held down and fighting really to get a sustainable environment going, as well as a sustainable economy. right now, 1.5 for these small and vulnerable countries is really talking about is whether they survive or they don't. we are talking about 1.51 to greece now, and people think that is just a figure, the 1.5to and people think that is just a figure, the 1.5 to stay alive. if you're a small states and have been subject to some of the biggest hurricanes of the last century in

the last four years, if you to mimic seen your whole island devastated and your economy wiped out and the sea rise and going up and up, you are looking at annihilation. for then, the recent they're here is they are having to say to the world, this is real. it is not a joke. and for us when, if we cannot get a real tool, is that 100 billion does not get delivered every year, and we've been promising it for more than ten years, at minimum, and people say we need trillions. but if we haven't even got the 100 billion, this is a death knell for many of our small states. and that's why they're here, round the table, banging the drum, saying please hear us. we round the table, banging the drum, saying please hear us.— saying please hear us. we were talkin: saying please hear us. we were talking about _ saying please hear us. we were talking about your _ saying please hear us. we were talking about your native - saying please hear us. we were - talking about your native dominica. just explain to people the ferocity of the storm are they're now facing.

these would be once—in—a—lifetime stance and now they come along with that much more frequency. what does that much more frequency. what does that mean for people who live there? it's terrifying. in the days, you would say, i'm going to face a category five storm, a category five hurricane once every 25 years. so once in my life i will face annihilation but then i can build back and hopefully be secure. in 2015, dominica, the country of my birth, suffered from tropical storm erica, it destroyed 95% of the gdp. so everyone thought this was the end of the world, it was terrible. two years later, not 72 years later, they were hit by the biggest hurricane of the world had ever seen at that stage, hurricane maria. it took away 226% of the gdp. and when

i went to see dominica, i couldn't recognise it. it was supposed to be the nature island, the most beautiful, lush island, it looked like armageddon. the hurricane had even struck depart from the trees. there was no green anywhere. a lot of people not only left the island but they lost everything. some people were literally left with what they were standing up in and everything else was gone. fine they were standing up in and everything else was gone. one of our everything else was gone. one of your other _ everything else was gone. one of your other members _ everything else was gone. one of your other members are - everything else was gone. one of your other members are india, i everything else was gone. one of. your other members are india, who has not come forward with a contribution, not committed to net—zero, and you sit in the same room as a commonwealth. but net-zero, and you sit in the same room as a commonwealth. but the issue in terms _ room as a commonwealth. but the issue in terms of— room as a commonwealth. but the issue in terms of india, _ room as a commonwealth. but the issue in terms of india, india - room as a commonwealth. but the issue in terms of india, india will. issue in terms of india, india will say, we have submitted ourfirst thought might, but were looking at how to upgrade those. every single country in the commonwealth

submitted the first ndcs and 44 of them have upgraded it. india is facing 1.36 billion people and they will say, if you look at what we've done, we've done more than many other countries, but there is a challenge and they are looking at is the other big guys, we are doing more than you, so we're going to argue about it. what the small islands are saying to india is, please help us. and the truth is, india has been very, very supportive of small island states, so are we hoping that everybody will come to the table, everybody will listen, everybody will see the reality? yes, we are, but every single country is looking at how they can help their own people and i understand that, i really understand that. but for the 32 small states in our commonwealth,

they may not have a tomorrow. for they may not have a tomorrow. for the 42 small states of the world, we can fix this for them. so maybe if we had the money of loss and damage, if we had the money to help with medication and adaptation, they may have more time, but right now, there is no time at it is going to take all of us. this is the really heartbreaking thing that, it's not that i can fix myself, i can't fix it unless you fix it with me. the truth is, it'sjust like with it unless you fix it with me. the truth is, it's just like with the vaccine is, none of us is going to be safe until all of us are safe, and up to now, the small states are like the canaries used to send down the mine and wait wait to see if they came back? they are our canaries and they are not coming back. the commonwealth has been fighting it since 1989 when we came up fighting it since 1989 when we came up with the conference. we fighting it since 1989 when we came up with the conference.— up with the conference. we have to leave it there _ up with the conference. we have to leave it there but _ up with the conference. we have to leave it there but thank _

up with the conference. we have to leave it there but thank you. - up with the conference. we have to leave it there but thank you. come | leave it there but thank you. come and see us again this week because there is a lot of debate and negotiation ongoing. thank you. the effects of climate change are already clear for some nations more than others. bangladesh is among the most vulnerable, so our science editor david shukman looks now at one village there and what it needs. in a village on the coast of bangladesh, people are using mud to try to hold back the sea. it's all they've got. the rising level of the ocean means they are getting flooded more often. and we saw the same villagers struggling in the same way back in 2009. the people who have done least to cause climate change are suffering the most from it. if the forecasts of climate scientists are right and the sea rises even more, maybe by a metre by the end of the century, how on earth are these millions of people going to cope? with life so precarious, this community has long been

desperate for international help. that is why this woman wanted to share her story at the climate summit in copenhagen 12 years ago. she told me she was pleased to be there and believed that world leaders would do something. they didn't. now her life is tougher than ever. extreme weather is striking more often, and there is still very little assistance. translation: we have no idea what we can do. - if people can help us, something can change. we don't have the money to move to other places. i have nothing that i can give to my children. along some stretches of coast, there are now rows of sandbags to try to keep the sea at bay. a new school provides shelter during cyclones. but fresh water is harder to find. most supplies are contaminated

by the rising sea. more than a decade ago, developing countries were given a promise that by now they would be getting $100 billion a year in climate aid. here we are at the glasgow summit, and that promise still hasn't been fulfilled. the 100 billion was just a promise that has not been kept, and its importance is that leaders who made the promise are not keeping their promise and therefore, these leaders have no credibility. back in bangladesh, she says she doesn't want her children and grandchildren to suffer more than she has. but they are facing a hotter and more hostile climate, so there's real pressure for the talks in glasgow to get somewhere. joining me is our science editor david shukman. we've been looking at the g20 communicate tonight and the new ones to language and what it means, it

doesn't matter to people in bangladesh, does it? they want help. that's right, it's a straightforward story of human needs. there are people around the world who are suffering more than most from the effects of climate change. in that village in bangladesh is having the whole lot chucked at it. the sea is rising meaning there is more coastal erosion and flooding and salt water will get into the field so there is less fresh drinking water. the pressure is very real and now. and thatis pressure is very real and now. and that is what you hear from people in bangor were so many other countries, that climate change isn't something to worry about in the coming decades, it's happening now, very acutely, and the need for help as immediate. acutely, and the need for help as immediate-— acutely, and the need for help as immediate. , ., ,, ., , ' immediate. they talk about this 1.5 de . rees immediate. they talk about this 1.5 degrees target. _ immediate. they talk about this 1.5 degrees target, that _ immediate. they talk about this 1.5 degrees target, that would - immediate. they talk about this 1.5 degrees target, that would help - immediate. they talk about this 1.5 degrees target, that would help us | degrees target, that would help us to something more like what we have at the moment but every degree, every 0.1 degrees after that, things get exponentially worse. it’s

get exponentially worse. it's sli -e get exponentially worse. it�*s slippery slope, it's not like the world is safe up till 1.5 or two degrees, we're in it now. and every extra degree, part of a degree, gets added, as you say, just adds more pressure to the system, it makes it, not immediately, that tomorrow is we're going to die in floods, but it makes the likelihood greater that you're going to get more extremes. and baroness scotland said it is an existential threat. it's not an existential threat. it's not an existential threat. it's not an existential threat sometime into the future, this is within eight years, it's now. �* , ., . it's now. i've been on pacific island nations _ it's now. i've been on pacific island nations which - it's now. i've been on pacific island nations which are, - it's now. i've been on pacific island nations which are, at| it's now. i've been on pacific- island nations which are, at their highest points, to follow is 1m above sea level. most are only a couple of metres above sea level. all it takes is a pretty high tide and there is a lot of flooding anyway. if you look at the climate models and projections, the 1.5 and beyond, its hard to see how they

won't be toast really quite quickly. and it's notjust little islands, it's bigger countries as well, think about all the cities on the coast around the world. and all this pressure is building and it does add to the urgency that ought to be applied here. to the urgency that ought to be applied here-— hundreds of passengers hoping to travel to glasgow for the cop26 climate summit by train have been left waiting inside london's euston station after a fallen tree halted services. pictures on social media showed the concourse packed with people, many of whom were hoping to travel north for the climate conference, which began today. travellers acknowledged the irony of the situation, as many were forced to book domestic flights to the conference on climate change as a result of the cancellations. let's speak to our reality check correspondent chris morris, who is also here in glasgow. i think you also came up by train,

my sympathy is to you, it has been a long old day. thank you forjoining us. we were talking about than 1.5 degrees targets, talk to us about the number and why it's so significant.— the number and why it's so siunificant. ., �* , ., ., significant. yeah, it's the amount of temperature _ significant. yeah, it's the amount of temperature rise _ significant. yeah, it's the amount of temperature rise there - significant. yeah, it's the amount of temperature rise there might i significant. yeah, it's the amount i of temperature rise there might be above preindustrial levels before we started chucking all these greenhouse gases into the air with industrial processes. as you heard from baroness scotland, at the moment we have 1.1 degrees, and the worrying thing, i think, is if you look at all the official clients that have been submitted to the united nations from countries around the world, if they all get plummeted as they are nothing else happens, we reach 2.7 degrees above preindustrial levels by the end of the century. that was in a un report last week, the un is very clear, that would mean catastrophic consequences. so they push to reach 1.5 is really an urgent one. part of the problem with the net—zero target

in 2050 is that it's quite a long way away. if you want to keep 1.5 within reach, you need to see real change in the next decade, by 2030. and at the moment again, looking at all the pledges that have been made, it's a lot lower thanjustice but years ago. for example, around 130 countries have now got legally defined targets ticketed net—zero or are actively looking at ways to get to net—zero by around the middle of the century. just a couple of years ago, no more than 20 countries, so you can see the pledges are building up, but it is turning the pledges into action and doing it the next few years, it has to start now. the litre sing tonight they have at least kept 1.5 alive but some big questions about the commitments made and allowing language in the communique. we have to leave it there, thank you very much indeed to

you. now let me handover to kasia madera in our studios for other news. some breaking news. a train has derailed on the line between salisbury and andover in the south west of england. the bbc understands there are no serious casualties reported, but around a dozen people have been injured at the incident near london road, close close to the city. these are the latest pictures we have received from the scene. british police say no one was killed in the train crash. let's cross to our correspondent frankie mccamley, who has more on this. this is coming into the newsroom but want to we know about what has happened with this rail derailment? these details are very much still emerging we arejust these details are very much still emerging we are just whining about

what has happened here but what we understand so far, this crash happened at about 6:a5pm this evening on the line between andover and salisbury. the rear of the carriage from portsmouth harbour that was travelling to bristol temple meads to wales after striking an object on its approach to salisbury station. we don't know what that object was. this derailment, they say, knocked out all of the signalling in the area and subsequently, the 17:20pm at south western railway service from london waterloo to honiton then collided with this bristol train. this derailed train is believed to have a carriage on its side, the train next to it is still up right at the moment but as you say, in the last few minutes, who had a bit of good news that british transport police say no—one has died in this railway crash. we just know a number of people have been injured and are walking wounded at the moment. qm.

walking wounded at the moment. ok, somethin: walking wounded at the moment. 0k, something for new there, thank you for bringing us up to date. we are monitoring the situation there, british transport police giving updates on social media and we are also monitoring here at bbc news. not the weather with louise. the rain cleared northwards and has been linking the far of scotland, a trail of showers following behind. as we say goodbye to october, what's in store for the beginning of november? we will start with sunshine and blustery showers and then it will turn quieter by the middle part of the next week. not speak over for most of us and we could see them overnight frost, something sinton not have so far this season. today's low moves away and we can track the isobars back to the north, so a

northerly wind take over before high pressure then builds in and quieten things down through the middle part of the week. it is that northerly wind that will be key to the story, noticeably cooler, driving in the blue turns across the country, temperatures just below par for the time of year. so, monday will be a case of sunny spells and scattered showers, most frequent out to the north and west. there will be some breaks, some sunshine coming through, but those temperatures dipping down a little. 944 degrees as a high. as we move out of monday into tuesday, the isobars will open up, the winds will fall a little lighter, we could have some frost and fog first thing on tuesday morning. but once that lifts away, there will be some sunshine around. most of the showers on tuesday on the exposed north coast of scotland, northern ireland and some running down through the irish sea as well. but even in the sunshine, it's not going to be very warm with it. a top temperature of between 9 or 12 celsius. moving out of tuesday into wednesday, similar story, still plenty of showers along the coast, but further inland,

it will be largely fine and dry. again, the potentialfor a frosty start first thing in the morning, but again that northerly wind just making it feel rather cool, really, and a bit of a shock to the system, particularly if you're caught in those showers. top temperatures between seven and 11 degrees as a maximum. high pressure builds in, then, as we move out of wednesday into thursday — that is going to quieten the weather story down. that'll kill off some of the showers as well. so thursday and friday looks likely to be drier and brighter, but not necessarily warmer. that is it. take care.

hello, this is bbc news. the headlines...

the crucial climate change conference has got under way in glasgow. the cop26 summit is widely seen as the last chance to save the planet from irreversible damage caused by climate change. earlier, the leaders of the world's richest nations were meeting in rome, where the climate challenge was spelled out clearly. if we don't act now, the paris agreement will be looked at in the future not as the moment humanity opened its eyes to the problem, but the moment we flinched and turned away. us presidentjoe biden said the g20 countries had made �*tangible' progress on climate, the pandemic and the economy and that the world was ready for american leadership on global issues. in our breaking news tonight — a number of passengers have been injured in a crash between two trains on the line between salisbury and grateley in wiltshire.

dorset and wiltshire fire and rescue have declared a critical incident
