of england, speaks to the bbc about the debt right—offs, international finance will have to make to obtain net—zero. what is needed to get us to 1.5 degrees is companies will have to do notjust say theoretically this is what is going to happen but actually i do have to write off some of those. immense relief as a 11—year—old girl, missing in australia for more than a fortnight, is found alive and well. this week, we have been driving less and walking more and also using hand sanitisers. and we'll be talking to one family about the practical changes needed to play a part in the fight against climate change. live from our studio in singapore, this is bbc news. it's newsday. welcome to the programme. we begin in glasgow, at the cop26 climate change conference. the british prime minister and host of the cop26 summit, borisjohnson, has said he's cautiously optimistic after some progress has been made by nations trying to find ways to reduce the effects of global warming. he added a note of caution though, warning against false hope. our political editor, laura kuenssberg, has been following the day's events. when cultures clash can they still agree? when there is so much difference, there can be dissent. shouting. there are so many faces in glasgow, so many facets of what could be done. mr dicaprio, are you pleased with what has happened this week? hollywood stars might campaign but less developed countries may well complain. the united nations fee as there is not enough trust to bridge the gaps, but deals are being made. more than 100 leaders signed a promise to stop the destruction of forests in nine years�* time. the american president displayed a real sense of progress. we are preparing to wrap on another busy day in scotland. i think we got a lot done. but there are obstacles. he was less than impressed that not every country is willing to be part of the journey. the fact that china, trying to assert a new role in the world as a world leader, not showing up? come on. the single most important thing that has the attention of the world is climate, everywhere. from iceland to australia. it is a gigantic issue. they have walked away. how do you do that and claim to be able to have any leadership now? the same with putin and russia. this is how tough it will be. away from the main stage, down a quiet corridor in a tiny office is big resistance. instead of president xi, one of the most powerful people you probably have never heard of in his place — china's climate negotiator. translation: my discussions l with john kerry and alok sharma were highly constructive. we found there were still huge gaps. he criticised developed countries for not coming up with cash to help the less wealthy go green and warned focusing too much on limiting global warming to 1.5 degrees, as borisjohnson wants, could destroy the consensus. but his attention was cast across as many foreign leaders as possible today but they have departed now, leaving instructions for their negotiators. around 100 countries have already signed up to cut the potent greenhouse gas methane by nearly a third by the end of the decade. the prime minister can bank progress on clean technology, as well as those promises on methane and forest but, remember, there are good reasons why only a day ago he was warning, overall, these talks could fail. i am cautiously optimistic in the sense that on the way to the g20 in rome i said to somebody on the plane, that if this was a football match then the current score would be 5—1 down in the match between humanity and climate change. i think today after two days of talks with around 120 world leaders is that we have pulled back a goal or perhaps even two. and i think we are going to be able to take this thing to extra time, because there is no doubt that some progress has been made. what, or who is going to score the extra two or three goals you need? if there is one thing that gives me confidence, optimism anyway, is that we are starting to create, for the countries that find it most difficult to transition away from fossil fuels, we are starting to create those coalitions of support to help them to move on. the first 48 hours here have been frantic and today there has been a flurry of promises that should hypothetically make a difference but it is now the hard bargaining really starts. remember, borisjohnson wants a deal that keeps global warming within safe limits but here in glasgow right now, it is far too early to be sure if that is in reach. there will be clashes and arguments, different voices and different views. do not underestimate how hard this is but borisjohnson cannot be sure what may greet him in glasgow if, at the end of this vast summit, he returns. laura kuenssberg, bbc news, glasgow. one of the significant deals approved by more than a hundred countries is a pledge to cut emissions of methane gas — a major contributor to global warming. the plan is to cut emissions by nearly a third by 2030. less encouraging is that three of the countries responsible for the highest level of emissions, russia, china and india, are not part of this agreement. 0ur science correspondent, rebecca morelle, has the details. from emissions from cows to rubbish rotting in landfill sites and flares from oil and gas, methane is escaping into the atmosphere but, today, more than 100 countries agreed to cut the gas by 30% in a deal brokered by the united states and the eu. we have to cut emissions fast. and methane is one of the gasses we can cut fastest. doing that will immediately slow down climate change. methane is an important greenhouse gas, making up about 20% of global emissions. it's extremely potent and has caused about 50% of current global warming. cutting all methane by a third by 2030 would reduce global temperatures by about 0.3 degrees by 2040. tackling methane from the oil and gas industry will be a priority. the easiest way to reduce emissions is to plug any leaks. you can't see methane unless you use a special camera like this one. it's a colourless, odourless gas but because it doesn't last for very long in the atmosphere, if you cut methane emissions now, you make a big difference fast. it's why reducing methane is seen as one of the easier climate fixes. but there will be challenges. agriculture, including rice production, is one of the biggest emitters of methane. solving that will be much harder. the countries who've signed up to this deal account for about half of global methane emissions. but there are some notable absences, namely china, russia and india, who haven't come on board. to achieve this 30% global target, we will need them to step up. but having more than 100 countries on board, including some of the largest emitters, and covering the vast majority of globally traded natural gas is a very big deal. this shows methane emissions around our planet. now, for the first time, there's a target to cut the greenhouse gas. this is a significant step for the world. rebecca morelle, bbc news, glasgow. mark carney is boris johnson's finance adviser for the conference and he's been speaking to the bbc�*s christian fraser. i think we will increase the links see, as government policy toughens up, what is needed to get us to 1.5 degrees is companies will have to do not just say theoretically this is what it will happen but actually i do have to write off some of those. with a tiny bit of that earlier, last year, about a year ago with some of the major oil companies who wrote off some of the excess reserves that just don't wrote off some of the excess reserves thatjust don't make sense in a 1.5 degrees world but it is a drop in the bucket thus far. i but it is a drop in the bucket thus far. ~ ., but it is a drop in the bucket thus far-— thus far. i know you are a supporter _ thus far. i know you are a supporter of _ thus far. i know you are a supporter of the - thus far. i know you are a supporter of the carbon i thus far. i know you are a - supporter of the carbon market as a way of generating financing getting finance to parts of the world that need it but one of the problems at the moment is what we call carbon leakage. you get territory like the eu who put the price up of carbon, carbon taxes, more expensive for companies, and then companies relocate to another part of the world where it is cheaper. do you think there needs to be thought about a global carbon price? i do think we — a global carbon price? i do think we need _ a global carbon price? i do think we need a _ a global carbon price? i do think we need a global - a global carbon price? i if think we need a global carbon price. it wouldn't exactly match the price, may be higher in the uk then it is in sub— sahara or developing africa or a small island state given the relative resources, but everyone should have a price on carbon but i am not naive about it. i don't think it will happen overnight. 0ne it. i don't think it will happen overnight. one of the objectives that prime minister trudeau and the prime minister of sweden and president biden and the head of the world trade organization and myself talked about yesterday was to get the coverage of the carbon price up to two—thirds of global emissions by the end of the decade. that will help reduce carbon leakage and of course, as you know, another issue in the absence of that is they could be trade barriers put in place because, to prevent the carbon leakage. let's take a look at some other stories in the headlines: voting has ended in a closely watched election for governor in the us state of virginia. exit polls suggest the race is tight between the democrat, terry mcauliffe, and the republican, glen youngkin. a number of other contests are taking place elsewhere, including for mayors and state legislatures. an advisory panel for the us centers for disease control has unanimously recommended that pfizer's covid vaccine be given to children aged 5 to 11. the regulator, the food and drug administration, has already signed off, and the biden administration plans to distribute 15 millionjabs. it could mean that younger children will get their first jabs in days. ethiopia's government has declared a state of emergency as war intensifies in several regions in the country. officials have urged people in the capital, addis ababa, to arm themselves as rebels from the northern tigray region advance towards the south. thousands of people have been killed since the conflict began a year ago. facebook�*s parent company says it's shutting down its facial recognition system and deleting a billion faceprints in response to privacy concerns. the decision affects a feature that automatically identified people who appear in digital photos. passengers travelling through terminal one at berlin's new airport are being warned not to drink water from any of the taps after potentially harmful bacteria was discovered. the bacteria, coliform, can cause vomiting and diarrhoea. a four—year—old girl, who went missing from a campsite on the coast of western australia more than two weeks ago, has been found alive. cleo smith was last seen in her family tent on october 16. police on wednesday morning broke into a home around 70 kilometres from the campsite and found the child in one of the rooms. phil mercer has been following the story for us from sydney. "my name is cleo", they were the four words spoken to police officers who broke into the property in carnarvon have entered a family pass nightmare, stretching back as you say, more than two weeks. authorities in western australia say they were acting on a tipoff, information leading to this address in carnarvon. we're not sure if a $1 million australian reward was significant in the breakthrough but cleo smith is safe and well and the authorities say she has been reunited with her parents. 836—year—old man with no apparent connection to the family has been into custody and is still being questioned. i as you said, a man is still in custody, do we know anything more about him? 0h in custody, do we know anything more about him? oh what we do know about him is that this has been one of western australia's biggest missing persons investigations. we have had drones and aircraft and satellite technology but also dozens of investigators trying to hunt down any clue for cleo smith. when she went missing on october 16, there was a huge land, air, and the search for the little girl. she arrived in the little girl. she arrived in the campsite when it was dark on friday evening. she was in bed by eight o'clock. sometime during the night she woke mother up for a drink of water and at 6am she was gone and police all the way through the investigation believe this was an opportunistic abduction because clio was sleeping in a separate room of the tent with her —month—old sister and the door to the tent, the zip was drawn up to a height that she couldn't reach and that was the basis of the investigation and safety say that an entire nation is usually relieved that this little girl has been found safe and well. you're watching newsday on the bbc. still to come on the programme: the family making the practical changes needed to play a part in the fight against climate change. the israeli prime minister, yitzhak rabin, the architect of the middle east peace process, has been assassinated. a 27—year—old jewish man has been arrested and an extremistjewish organisation has claimed responsibility for the killing. at polling booths throughout the country, they voted on a historic day for australia. as the results came in, it was clear — the monarchy would survive. of the american hostages, there was no sign — - they are being held somewhere inside the compound — - and student leaders have threatened that, should i the americans attempt. rescue, they will all die. this mission has surpassed all expectations. voyager one is now the most distant man—made object anywhere in the universe, and itjust seems to keep on going. tonight, we prove once more that the true strength of our nation comes not from the might of our arms or the scale of our wealth, but from the enduring power of our ideals. this is newsday on the bbc. i'm mariko oi in singapore. our headlines: leaders at the climate change summit in glasgow make progress in the race to limit global warming. the cop26 host, boris johnson, says that so far he is cautiously optimistic about the advances being made. let's stay with events at cop26 and talk about what president biden is calling a �*game—changing commitment�* — world leaders have pledged to cut methane emission levels by 30% by 2030. dan lashof is a director at the us branch of world resources institute, a global environmental think tank. thank you so much forjoining us. what do you make of these new rules? is mr biden right to call them game changing? i think it is. methane is the second most important heat trapping pollutant in the atmosphere and this concerted effort both globally and through a set of rules announced in the united states todayis announced in the united states today is taking the biggest step yet to curb emissions and that can have a rapid effect on curbing global warming because of the relatively short lifespan of methane in the atmosphere. lip lifespan of methane in the atmosphere.— lifespan of methane in the atmoshere. , ., atmosphere. up until now we have been — atmosphere. up until now we have been focusing _ atmosphere. up until now we have been focusing on - atmosphere. up until now we have been focusing on c02 i have been focusing on co2 emissions. can you talk us through weight is so important to curb methane and why now? over a 20 year period methane emissions trap about 80 times as much heat as carbon dioxide and methane has been rising more than twice as fast as carbon dioxide in the atmosphere. we know that there is a diverse set of sources of methane but leakage from the oil and gas industry is one of the biggest sources and one of the biggest sources and one of the easiest to tackle because we have new technology to detect lee's and we can impose requirements for oil and gas companies to detect leaks and repair them when they are found. you mentioned oil and gas but, also, the agriculture sector is crucial as well. and when china and india are not part of this, is this commitment actually going to make that much of a difference? cultural sources of methane are harder to address but there are innovations being worked on and i think over 100 countries that are part of this pledge will be working on agricultural innovations as well as controlling oil and gas ethane and if those innovations are successful then i think we can expect to and india to adopt them as well which will increase their impact. what is our increase their impact. what is your assessment _ increase their impact. what is your assessment on - increase their impact. what is your assessment on the - increase their impact. what is| your assessment on the biden administration? what more can the us administration do? this methane initiative _ the us administration do? t�*i 3 methane initiative today is one part of a comprehensive agenda that president biden is putting in place. he has done more in his first year in office than any other us president in that time period and in addition, the methane rule announced today he is taking steps to tighten rules on emissions from automobiles and also proposing rules to curb emissions of h c —— h rules to curb emissions of h c -- h fc's rules to curb emissions of h c —— h fc�*s super pollutants and before congress is a historic investment, over $550 billion investment, over $550 billion in climate action that we expect will pass sometime in the next few weeks.- expect will pass sometime in the next few weeks. thank you so much for — the next few weeks. thank you so much forjoining _ the next few weeks. thank you so much forjoining us - the next few weeks. thank you so much forjoining us on - the next few weeks. thank you so much forjoining us on the l so much forjoining us on the programme. we've been hearing about the grand agreements leaders are trying to reach, but what can the rest of us do? reducing carbon emissions could mean all of us changing our habits — from what we buy, to what we eat. our science correspondent victoria gill has been to meet one family who are looking to the future. busy family life makes it difficult to count our carbon emissions, but for this family in leeds, decarbonising their daily routine has has become a priority. i think edie constantly likes to remind me that i need to be better. do you think it could be made easier, you know, to make the changes that you would like to make? it would be better for the environment if we switched to eating more plant—based things, but we don't really do a lot of that at the moment and we could be better that. as a parent, iam busy, but actually, i need to just make these changes for the better, really. it's kind of the next generation that will be left with these problems. and we'll all need to be part of the solution. according to one in—depth study of our energy use, the uk could halve its demand for energy by 2050 without compromising our quality of life. we've got to reduce emissions so quickly over the next ten years that it means that everybody needs to be involved in the debate and in positive changes. low emissions, researchers say, means less consumption. as well as cutting our meat intake, most of us could reduce how many calories we eat. buying less and repairing more could help make a dent in the mountain of electrical waste we produce every year, and researchers are calling for investment in public transport and cycling networks to increase tenfold in the next decade to help us all decarbonise our travel. to work out what that means for the day to day, we organised for edie and jo to get expert advice. i'd never want anyone to feel guilty about their carbon footprint. it's not always easy to make changes. you could consider journeys under a particular distance, a shortjourney, could be done by cycling or walking. well, we are definitely up for the challenge, aren't we, edie? yes, we will try our very best this week. come on, mister! we are just about to walk to the shop. this week we've been driving less and walking more and also using plant —based alternative. edie, jo, how did it go? the challenge? we started this week. we tried really hard to walk where that was reasonably practical, but i don't think we ate as many plant—based alternatives as we could have done. i think they've done fantastically well. lots of the changes can lead to a healthier, more active lifestyle as well, and i think that is what's positive about this. to slash our emissions as quickly as we need to, scientists say most of us will need to rethink our daily habits and consume a little bit less. victoria gill, bbc news. and before we go we want to wish a happy birthday — to ourselves. bbc tv is 85 years old. at 3pm local time on november 2nd, 1936 the bbc launched its first regular tv service from north london. there was a newsreel, a variety show, music — including the first—ever performance by the bbc tv orchestra. viewers were called �*lookers in�*, and there weren't many of them. only about 400 on the first day. then — as now — our mission was to inform, educate and entertain. and now for some glamour. royal jewels smuggled out of russia during the 1917 revolution are going up for auction next week in geneva. they include a pink diamond weighing more than 25 carats expect it to fetch up to $6 million. that is a little out of my budget. that's all for now — stay with bbc world news. hello there. it's staying pretty cold now for the rest of this week. there will be quite a bit of sunshine around by day, but it will be chilly at night with frosts and fog in places. now, through the day there will be quite a bit of sunshine in central and southern areas, but also some showers. this mainly affecting coastal areas. got low pressure to the north of the uk, this is where we are seeing the strongest of the winds today and weather fronts enhancing the shower activity. although most of them will be affecting coastal areas all around the country down into west wales and the southwest, northern parts of northern ireland and much of the eastern side of the country. some of the showers across the northeast, east of england will push into the midlands. so a bit cloudy here, more than we have had the last few days. some of the showers heavy with some hail and thunder mixed in, and they will be wintry over the high ground, particularly across northern scotland with the strongest of the winds. further south the winds will be lighter. it's going to be a chilly day wherever you are, highs of six to eight in the north, nine to 11 further south. through wednesday night it stays quite blustery in the north, further coastal showers and many central areas will turn dry with lengthy clear skies again. winds will be lighter here. but stronger winds across the eastern side of england, more cloud. not quite as cold here as what it will be further west, and across the north we will have some frost and also some patches of fog. now as we move towards thursday into friday we start to see a change to the weather. this area of high pressure begins to build in from the west. it kills off lots of the showers, but what it is also going to do is cut off the arctic air supply as our wind begins to veer more west and southwesterly direction. so that will bring milder air back to our shores as you can see here from the orange and yellow colours. thursday, then, another cold start with frost and fog around. and then it is bright. plenty of sunshine around, more sunshine around on thursday. still a few showers across the eastern coasts again down into the far southwest. later in the day, thicker cloudy, patchy rain pushing into the northwest of the uk as we start to pick up westerly winds. temperature slowly rising here, otherwise for most again it is a chilly day. as we move out from thursday into friday we start to see an area of high pressure toppling down towards the south of the country, and that will allow this area of low pressure to move in across the north at the start of the weekend. so it will be turning milder towards the end of the week, particularly as we head on into the weekend. low pressure will start to bring wetter and windier weather to northern areas, and will tend to stay drier and brighter the further south and east you are. this is bbc news. we will have the headlines and all the main news stories for you at the top of the hour, straight after this programme. this week — catching carbon. scannable snacks. and food, made from thin air. tick, tick...
