hello, i'm ros atkins. this is outside source. thousands of scientists from around the world have joined forces to declare a global climate emergency. they say forty years of data points to a world facing "untold human suffering" if significant change isn't made. in the us, more impeachment inquiry testimony is being released. america's ambassador to the eu revised his testimony to say aid to ukraine was dependent on president trump getting what he wanted. anthony zurcher in washington will be here to talk us through. cheering a smiling springbok player and his

coach. this is south africa's rugby world cup winning team being given a hero's welcome injohannesberg. here in the uk, parliament has been dissolved ahead of the december election. a senior member of the conservative party, jacob rees—mogg, has had to apologise for suggesting the victims of the grenfell fire lacked common sense. a group of 11,000 scientists has endorsed a stark message on our climate. it's based on a new study that looks at a0 years of data and which concludes, "the climate crisis has arrived and is accelerating faster than most scientists expected. it is more severe than anticipated, threatening natural ecosystems and the fate of humanity." it does, though, also say action taken now can make a difference. here's the bbc‘s science editor david shukman. what we have here is a very large

number of scientists who, actually, in a sense, lost patience. they point out that exactly a0 years ago, there was a world climate conference which warned of the urgency of tackling climate change, as greenhouse gas emissions were due then to shoot up and cause a whole range of impacts. and they say that, effectively, nothing has been done. and i think what we are seeing more and more is scientists breaking out of the straitjacket you'd expect them to be in. what you want from scientists, or what the public might think of hard facts, hard analysis, no emotion. what the scientists themselves are coming up with now are projections, warning signs that they feel are so worrying that they have to speak out, they have to get emotional. they say there's now a moral obligation on scientists to speak up and to use ever blunter language, so that's what we're seeing now. the report names six areas where improvements would have an immediate impact — including energy,

land clearing and food, as well as population growth. scientists says the world needs to stabilise the global population which is growing by around 200,000 a day. here's david on why that's controversial. it's incredibly sensitive. because if you start saying, "oh, there are too many people" — and sort of statistically, scientifically, you could make thatjudgement — what are you actually going to do about it? so the chinese had their one—child policy and say that that created a climate benefit for the planet, which they haven't been rewarded for, they say. what are you going to say to the catholic church, the vatican, about birth control? you immediately smack into some terribly difficult, culturally, religiously sensitive issues. but this document suggests that some scientists are willing to do that? that's indeed the case. and for some years, you've had people becoming perhaps a little more outspoken about this topic, bringing it up or saying it should be brought up in internationalfora.

but that isn't really happening. imagine you've got a room full of all the governments on the planet. all kinds of trade—offs, difficult negotiations, sensitivities. population is something that, so far, they've steered away from. also relevant to the climate emergency is america's withdrawal from the paris climate deal. we knew this was coming — but it's now been formalised — and will be completed in a year's time. it will make america the only country not participating. this is president trump in 2017 when he took the decision. the united states will withdraw... applause ..but begin negotiations to reenter either the paris accord or an entirely new transaction with terms that are fair the paris deal commits 187 countries to keeping global temperatures to below two degrees celsius above pre—industrial levels — with the goal to stay below 1.5 degrees.

well, america might be out, but emmanuel macron is in china to sign a declaration that states the irreversibility of the paris accord. and he's been speaking. translation: if we are to comply with the paris accord, we will have to increase our commitments on emissions next year. we will need to confirm new commitments for 2030 and 2050 and cooperation between china and the european union is decisive in this respect. going it alone is not a good decision for anyone and is not possible for everyone. now, this is a report by the institute of international and european affairs last year. now, this is a report by the institute of international it suggests president trump's decision to leave the paris deal has done "very real damage" to it. the institute says it created "moral and political cover for others to follow suit".

but so far, others haven't followed suit. here's david shukman again. the big worry is if america isn't playing ball in this process, will other countries think, "well, how seriously do we need to take it? will our international reputation be damaged if we're not really stepping up to the plate on cutting emissions if america isn't doing that?" i think the really key thing here is china, the response of china. we are waiting, in the coming months, for the next chinese five—year plan. and there've been hints that they will step up, they will increase the level of their ambition to cut their greenhouse gases in the coming years. that's a hugely significant step. if they decide they're going to show climate leadership, they're not going to worry about america, well, maybe the process will run as before. if they decide, the other big partner isn't playing, we won't bother, that will be very serious indeed.

next to washington. congress has released more testimony from the impeachment inquiry into donald trump. this all centres around a phone call mr trump made to the ukrainian president injuly. in it, he asked ukraine to investigate his poltical rivaljoe biden. the accusation is us military aid to ukraine was being withheld until that investigation was agreed to. first, the us ambassador to the european union, gordon sondland, says he told senior officials in ukraine they probably wouldn't get military aid until they launched the investigation intojoe biden, and his son hunter. kurt volker, the former us ambassador to nato, says president trump told white house aides to talk to his personal lawyer, rudy giuliani, about issues to do with ukraine. let's speak to anthony zurcher live with us from washington, dc. first

on the process here, it feels very choreographed from the democrats, with testimony peering the day after day. is this design for political impact or is this the standard process 7 impact or is this the standard process? i think you have to view everything in a political context in this point. the democrats have released two of the transcripts today. before they release the actual transcript, they released state m e nts actual transcript, they released statements that highlighted what they thought were the most important portions of it. clearly, they are trying to time this for the maximum political effect but the relativity is eventually, the information gets out there and all of us can pick over it then. and the issue that eve ryo ne over it then. and the issue that everyone is looking for is, is there proof that donald trump tied the military aid to the investigation intojoe military aid to the investigation into joe biden? does military aid to the investigation intojoe biden? does the testimony today back that idea of?” intojoe biden? does the testimony today back that idea of? i think the key thing and what we found out about today was gordon sondland's revised statement that he released today, that was appended onto his testimony from last monday to make

—— the last one. he is saying... tim morris, the national security officer reported this. that he had this meeting with ukrainian officials and he told them directly that's it was likely this military aid wasn't going to be resumed until you had this anti—corruption statement. what he meant by this was the ukrainians announced that they we re the ukrainians announced that they were investigating the energy company with ties to joe were investigating the energy company with ties tojoe biden‘s son. it also investigated the 2016 election for this kind of off the wall theory that ukraine was actually behind it and not russia. here you have a real tangible first—hand evidence from a political appointee, where he was saying that this was likely a quid pro quo, that they were going to get the military aid in exchange for doing these investigations. and just quickly before let you go, another question

on the process. the democrats here all this testimony, what happens? they add this up to what they think might have happened? yeah. they will have public hearings next, in the coming weeks, and will be reviewed by thejudiciary coming weeks, and will be reviewed by the judiciary and they will decide whether to draft articles of impeachment. i want to add the white house has already come out with a statement and they have said that gordon sondland's testimony does not change anything, that he was making assumptions about the white house intended. that was his doing and nothing that would alleged impropriety by the president himself. anthony, thank you very much indeed. in the white house maintains all of this is to do with the election coming in a year's time. let's focus on that. national polls indicate that joe biden remains the frontrunner in the race for the democratic presidential nomination. the first vote on who will be

the democratic nominee will happen in the state of new hampshire, in 100 days' time. jane 0'brien is there for us. have you have gone 0utside source. help me out here. if we look into history, is new hampshire a good guide for how the democrats will go? what it does is actually windows the field. by the time the you have your primary is over and done with, we will know who the serious contenders are. will that include joe will know who the serious contenders are. will that includejoe biden? we wa nt to are. will that includejoe biden? we want to know. in new hampshire in 2016, they actually voted for bernie sanders. he is sending for the nomination yet again, and everybody here loves bernie but they are also very worried that if they pick a candidate too far to the left, they're going to ruin their chances for gathering support from independents and moderates that they're going to need if they're going to unseat the president. and thatis going to unseat the president. and that is why you're seeing a discrepancy between joe biden, topping the national polls, and others like bernie sanders, elizabeth warren, who are topping

the pulse here in new hampshire. but there is nojoke here. you any democrat in new hampshire who they're going to vote for as the candidate and they will say, i don't know, i've only met them twice, because all the candidates are here all the time at the moment and one person who is been following this very closely is this democrat. i spoke to him earlier and asked him who he is going be voting for. i have a few who are my favourites, and they're all wonderful. but there are couple that stand out. lisbeth warren is so smart with the economy and pete buttigieg is so smart with people on the margins, and cory booker is so good at understanding people of all flavours, including those in the inner—city, and so we are going to be great with the nominee is. why is it so difficult to decide? what are you looking for? what do you balancing here? in my

opinion, what mexico located is they we re opinion, what mexico located is they were so opinion, what mexico located is they we re so many opinion, what mexico located is they were so many who opinion, what mexico located is they were so many who are opinion, what mexico located is they were so many who are incredibly smart and good —— what makes it incredible he complicated. especially when you put that up against what we have in the white house right now, a lot of concern about fairness toward our neighbour, and understanding about being honest and understanding about being honest and truthful, and all of the people oi'i and truthful, and all of the people on the democrat excited or so capable. it's a wonderful time to be a democrat in the united states. but are republicans going to be persuaded by the person you pick? do you think they will actually vote for a democrat given that the country is so polarised right now?|j cannot country is so polarised right now?” cannot speak to that, of course. i hope that my neighbours, who identify as republican, take this as an opportunity to think deeply and really wrestle with themselves about what it means to be a good american, who we are, our whole history of

welcoming people in carving out space for people who maybe need some, someone space for people who maybe need some, someone to advocate for them. we have spoken many times about the washington newsroom, the never ending maelstrom there. i wonder if there are other issues driving the cause of choice of candidate? that's a very good question because i feel like i am ina good question because i feel like i am in a parallel universe. in washington, the impeachment inquiry. up washington, the impeachment inquiry. up here, no one is talking about it. people saying, it is ridiculous, it just shows there is a democratic elite getting donald trump. it is difficult to pin point the one thing, the economy really important, health care, the afforded ability of health care, the afforded ability of health care. but i think at the end of the day, this isn't going to be

so of the day, this isn't going to be so much an issue led campaign, it's going to be about the candidates. can donald trump hold onto his face? can donald trump hold onto his face? can he pull some independence if there are any left onto his side? he is going to need them if he is going to win. and candy democrats come up with a candidate who will give them a warm, fuzzy feeling and get them out to the ballot box as well? i think at the end of the day, it's going to be personality rather more than issues. jane, lovely to talk. see you soon, i'm sure. life for us in new hampshire. 100 days until the primary new hampshire. about a year until the 2020 election. stay with us on 0utside source. still to come: we'll report on the deadly attack on a us family in mexico. with the help of bbc mundo, we will outline what happened. scientists say a do—it—yourself test

could revolutionise screening for cervical cancer, which is at a 21—year low. 0ur health reporter michelle roberts has the details. smear tests can be life—saving, but millions of women are not going for them. women aged 25 to 64 in the uk are invited for checks, but the number taking up the offer has been falling. now researchers say a new form of test carried out by women themselves at home could get more people screened. it is detecting 96% of women who have a high grade lesion, or a precancer lesion. so it is very efficient, but, because it is to replace another test, we need to do this in 10,000 women. campaigners say home testing would be popular, but larger trials are needed before the nhs can decide whether to offer it. michelle roberts, bbc news.

this is 0utside source live from the bbc newsroom. scientists from around the world are warning about a "clear and unequivocal" climate emergency. their study is based on more than a0 years of data. in mexico, at least nine americans have been killed in a attack by suspected drug cartel gunmen. this happened in sonora on the us—mexico border. this is the aftermath. you can see a completely burnt—out suv. the victims include six children. the family are linked to a breakaway mormon community which settled in mexico. a cousin of one of those who died has been speaking from salt lake city in the us. helpless families are being innocently killed down there. these are us citizens. it's notjust got caught in gunfire in the wrong

place at the wrong time. this was a whole new level of cartel violence. as of this point, it's not over. we still don't know what's going to happen next. a family portrait has emerged of one of the victims and her children, several of whom were killed, including the babies in arm. donald trump has tweeted about this. a message to president lopez 0brador, and he replied with this. translation: we have all the cooperation we need now. i'm going to tell president trump thank you very much and see how they can help, while preserving our sovereignty — as they do and as all countries do. bbc mundo's cecilia barria. in the northwest of mexico, at least there are two cartels that are

trying to get control of that area. nevertheless, we don't know exactly which one of the cartels could have been involved in this incident. and it's comic hated because some of the family members have said that they could be caught in crossfire or they could be caught in crossfire or they could be, could have been the target of some of the drug cartels that are operating in this area —— and is complicated. what is more shocking related to this incident is some of the family members, particular children, may have been burned alive. so this is not the first of —— first time these incidents are affecting the mormon community because they been the target of kidnappings and also extortions throughout the last decade. and tell us more throughout the last decade. and tell us more about the history of this mormon community and how it came to be in this part of mexico? they are breakaway of the mormon church in

the united states. decades ago, they moved from the us to mexico trying to have a peaceful life and they have a kind of peace agreement at that time with the central church in the us. they have been living there. basically, doing some farming activities, and they have been able to have a kind of economic situation over there but they have been in the middle of this fighting between drug cartels, try to control the territory. the older sister of former islamic state group leader abu bakr al—baghdadi has been captured in northern syria. she was detained in a raid on monday near the town of azaz, in an area of aleppo province under turkish control. president erdogan's senior aide said... i was going to show you, is not

there. the arrest of al—baghdadi's sister is yet another example of the success of our counter—terrorism operations. al—baghdadi lead is for a number of years. but he killed himself during this us raid last month. this is footage of the raid the americans released. his sister, who is 65 years old, was ca ptu red his sister, who is 65 years old, was captured last night in a camp with her husband, daughter—in—law and five grand children. her husband and daughter—in—law were interrogated by turkish officials, and one of the turkish officials, and one of the turkish security officials says it's a golden mind to find her, to get more information about isis. we don't know she was a part of isis, but we know is he trusted most of his family and to the husbands of his family and to the husbands of

his sisters, actually, so what turkish officials hope is to get more information about his daily life, how he used to make his decisions about the organisation and how he ended up in invalid. —— in idlib. apparently to capture more isis fighters who are on the run. think to abc turkish. —— thanks to bbc turkish. let's talk about facebook. it is rebranding itself to convey optimism, it tells us. you ready for this? here is the old logo — and this is the new one. it'll be used by the parent company that owns whatsapp and instagram but the facebook app and website itself won't change. if that's clear. help me out. we have got essentially

two entities with the same name but different logos? we will have facebook the company, and that is where you will see the all caps, which will be separate to facebook the app, which many people use every day. i will remain using smaller letters a nd day. i will remain using smaller letters and the blue and white colouring we are all so familiar with. facebook is trying to do a few things here. i think it is try to make a differentiation the app also is also taking ownership of the fact that it owns so much of the social media landscape, and i had a look at my own phone before coming to talk to you, and just try to see where it was on whatsapp and instagram that facebook knowledged those platforms. i found it a very small font, and facebook knowledged those platforms. ifound it a very small font, and in a few weeks, we can expect to see the new, all capitalised logo, and will be brighter. whether that is optimistic and the people have to make them —— whether that is optimistic, people and to make up

their minds for themselves. have to leave it there, vivian. thank you. if you're in the uk and want to fly a drone weighing more that 250g, you will need to register online and pass an online test. 250g is less than a tin of soup, i'm told. theo leggett explains. drones come in the use of them come has been growing massively of the past for years. if you to commercial drones. back in 2010, i think there we re drones. back in 2010, i think there were five commercial licenses. now there are 4500. and there were hundreds of thousands of the things. and really come of the rules have not kept up. this is about bringing the rules in line, making sure if you're operating something more than a very light weight, you are not going to fly into areas you should not do and be careful around people so not do and be careful around people so that if it does drop out of the sky, which happens from time to time, it does not fall on someone. what relators are doing here is catching up. the industry has overta ken catching up. the industry has overtaken the regulators, but most countries have something similar. under 250 grams, lightweight little

models, toys, you're pretty much ok. over 250 grams, and up to between 20 and tony five telegrams, in france, the limit is axley100 grams. in canada, anything over 250 grams come up canada, anything over 250 grams come up to 25 kilograms, it's got to be registered. you have to have a certificate. in nigeria, it's over 250 grams. in the united states, yes, similar sort of thing. in about three minutes, when i come back with outside source, we have heard from all the parties. boris johnson has been talking about brexit, jo swinson has been talking about brexit and — you'll see where iam going about brexit and — you'll see where i am going here —jeremy corbyn has been talking about brexit. all three parties talking about what they would do, talk about why there are flaws in with the others would do, so we flaws in with the others would do, so we will look at that, play all the relevant clips and look at what

is increasingly a bitter online information battle. see you in a couple of minutes. hello there. what has been going on in east africa. some flooding problems in different countries but these are the latest scenes coming out of somalia, with people struggling in neckdeep floodwaters in places. it's difficult to verify just how much rain has fallen over recent days and weeks. according to the united nations high commissioner for refugees, some 270,000 people have been displaced by flooding in the last two weeks alone. there are eight flights going into these parts of africa. on the side like picture, we have more storm clubs working to central areas of somalia and there is more rain in the forecast over the next few days. the flooding likely to get worse in places before it gets better. we'll probably start

to see the ring turn heavier once again and part of kenya and eastern areas of tanzania as well, where we could see flooding issues. the rain is heavier than normal because of the extra warmth or is in the western indian ocean. not1 million miles from there, we - this, a miles from there, we have this, a cyclone. you can miles from there, we have this, a cyclone. you 1 tropical
