hello, i'm ros atkins, this is outside source. president trump's impeachment trial has formally begun in the us senate. supreme court chiefjustice john roberts has been sworn in to preside over the trial which starts next week. this is the democrat's central allegation. president trump's solicited the interference of a foreign government, ukraine, and the 2020 united states presidential election. a global study has found that sepsis — also known as blood poisoning — is the cause of nearly a fifth of all deaths worldwide — that's more than double the number previously thought. as the bbc begins a special series on climate change, sir david attenborough warns that the world has reached a pivotal moment. the moment of crisis is calm. we can

no longer pre—barricade. —— the moment of crisis has come. as i speak, southeast australia is on fire. and ministers from five nations which lost citizens in the ukrainian airliner shot down by iran are demanding compensation and full co—operation. the stage is set for the impeachment trial of donald trump. it will begin on tuesday. here is the chief justicejohn roberts. he's been been sworn in to preside over the trial — along with the 100 senators who have been are being sworn in as jurors. prosecutors appointed by the lower house, the house of representatives, have been reading out the charges. impeaching donald john trump, president of the united states, for high crimes and misdemeanors.

donald] trump has abused the powers of the presidency in that using the powers of his high office, president trump solicited the interference of a foreign government, ukraine, in the 2020 united states presidential election. the impeachment inquiry in the house of representatives was full of drama — particular long testimonials from witnesses. the republican leader in the senate is promising things will be different this time. this chamber exists precisely, madam president, so we can look past the daily dramas and understand how our actions will reverberate for generations. so that we can put aside animal reflexes and coolly consider how to best serve our country in the long run. so, madam president, the house's hour is over. the senate's time is at hand. for more on what's at stake

here in us politics, here's our correspondent in washington, gary o'donoghue. this is history in the making. to throw a cliche at you if you like. this just doesn't happen very often. we know this is only the third time in the history of the united states that this has happened. it is meant to be rare, the founders hoped it would be rare and it has been rare. so here we are, with the articles of impeachment having been delivered to the senate, as mitch mcconnell was saying, it is now time for them to turn themselves into a quasi—court, but a court in many ways staffed with jurors, who are also politicians at the same time. they have taken their oath now, they've had the articles read to them, they have suspended their proceedings until 1pm next tuesday, when the real business of the trial will begin. the ceremony not the only important moment of the day.

remember, the central accusation here is that the trump administration held back military aid to ukraine in order to pressure the ukrainian government to investigate mr trump's political rivaljoe biden. now today, the government accountability office has said that the white house broke the law when it withheld military aid to ukraine in the summer. on this, here's speaker of the house nancy pelosi. these are the words of the gao — faithful execution of the law does not permit the president to substitute his own policy priorities for those that congress has enacted into law. the office of management and budget withheld funds for a policy reason which is not permitted under the empowerment control act. for more on the significance of the trump administration being found to have broken the law, here's gary o'donoghue again. it is not significant in the sense of any prosecution or anything like that. this is thejudgement of any prosecution or anything like that. this is the judgement of a government watchdog in effect and what they are saying is congress has

the power of the purse, under the constitution, when it is decided to use suspend money in a certain way, as it did with the military aid to ukraine, you better go and spend it. and how it holding onto it, as they did at the white house, for almost a year, holding on for that length of time, and for the reasons we think you held onto it, it is against the rules. having said all of that, the budget office inside of the white house, the office of management and budget, completely disagree with them and say we had every right to hold onto it because of the president's foreign policy concerns. you have a clash of the watchdogs if you like, one says yes, and the other says no. also — the ukrainian government has started an investigation into claims that marie yovanovitch, the former us ambassador there, was subjected to illegal surveillance. these text messages released to the us congress on tuesday suggest her movements were being monitored. this one says for example says: "she talked to three people, her phone is off, her computer is off. " the texts reveal that an associate

of mr trump's personal lawyer rudy giuliani, called lev parnas, seen here together in washington, was apparently given updates on the ambassador‘s location and mobile phone use by this man robert hyde, a republican congressional candidate in connecticut and a donor to the trump campaign. mr hyde has denied being involved in surveillance of ms yovanovitch, saying he was "justjoking" in the texts to lev parnas. for her part, marie yovanovitch is calling for an investigation into the messages. her lawyer has said in a statement: "the notion that american citizens and others were monitoring her movements... is disturbing. for more on this, here's jonah fisher in kyiv. ukraine has been spurred into launching this investigation by the publication in the united states on tuesday of text messages, more accurately, whatsapp messages, that were sent between a close

associate of president trump's personal lawyer rudy giuliani, a man called lev parnas, and a trump supporter in the united states called robert hyde. those messages clearly indicate that the american ambassador here in kyiv in the first part of 2019, a woman called marie yovanovitch, was being pretty closely watched. they suggest her movements were being tracked, communications were being tracked and in fact there are pretty sinister messages there, almost implying that there might be some sort of possibility of paying people here in ukraine for something bad to happen to her. so today ukraine's interior ministry responded by saying it was launching an investigation into what is said was possibly illegal surveillance that might contravene both ukrainian law and international conventions on how diplomats should be treated.

so at long last, there is a bit of an irony in this, ukraine is launching an investigation, but this isn't the investigation that president trump has been calling for so long for. it is an investigation into whether the american ambassador here in ukraine in the first part of last year was basically being spied on, being monitored, by the close supporters of president trump. lev parnas is a ukrainian—american businessman and republican party donor. he has accused the president of lying about what he knew of his administration's dealings with ukraine. mr parnas was asked in an interview on msnbc: "what do you think is the main inaccuracy or the main lie that's being told that you can correct?" this was his reply. that the president didn't know what was going on. president trump knew exactly what was going on. he was aware of all of my movements. i wouldn't do anything without the consent of rudy giuliani or the president.

i have no intent or reason to speak to any of these officials. they have no reason to speak to me. why would president zelensky‘s inner circle or the minister or all of these people meet with me? who am i? there's a photograph that's been published in us media of president trump with mr parnas. although the president denied knowing him when asked about it byjournalists at the white house. if i have a picture where i'm standing with somebody and a fundraiser, i saw a picture with this man, but i don't know him. i never had a conversation with him that i remember. let me just tell you. you have to take a look at the polls. well for more on why this aide to rudy giuliani has been speaking out against the president, here's gary o'donoghue again.

well, he is trying, according to his critics, to ingratiate himself with the authorities and to keep himself out of prison because he is facing those charges. and he is handing over a lot of this material to congress, his lawyers have done that. interestingly, he changed lawyers early on in the process after he was charged initially. he had a lawyer who worked for president trump before but now he is working with some different lawyers. and his credibility is being questioned as you can imagine. but the question will be is whether or not some of this evidence he has given, he is talking about pressure being put on notjust zelensky but the previous president as well, whether any of that will see the light of day during the trial, democrats would like that very much. 0h oh howi oh how i feel coverage of the trial starting on tuesday. —— we will have full coverage.

a global study has found that sepsis kills more people than cancer. the study‘s extraordinary finding was that sepsis kills 11 milion people a year — equivalent to almost a fifth of all deaths worldwide — that's more than double the previous estimates. the nhs website defines sepsis as "a life—threatening reaction... when your immune system overreacts to an infection and starts to damage your body's own tissues and organs." the study published in the lancet found the problem was most acute in sub—saharan africa. he also can see india and parts of south america are affected. one doctor here in the uk tweeted... sepsis is already something health services across the world are very alert to the dangers of. ron daniels from the sepsis trust here in the uk can tell you how to spot it. we all know what having an affection

feels like. we feel unwell in my go to bed, but if something is triggering an alarm bail, be prepared to phone 111 ehrlich senior gp and ask her to be sepsis. —— an affection feels like. there are six key symptoms to look for. they spell the word sepsis. we have asked for slurred speech or confusion, e4 extreme pain in the muscles or joints, p for passing no you're in, no water in a day, as for severe breathlessness, ie for it feels like i'm going to die and people really do describe that, in the final s for muscle discoloring or pell. any one of those symptoms are on a website on the nhs website, get yourself straightaway to be checked. we talk about climate change daily on outside source — today, sir david attenborough has had this to say. we have been putting things off year after year. we have been raising targets and saying if we do it within the next 20 years, or... the moment of crisis has come. we can no longer pre—barricade.

sir david has presented natural history programmes for over 50 years — many for the bbc. and his comments mark a year of special coverage of climate change on the bbc. it's called our planet matters. its website has news services, programmes and coverage of climate debates and events. so what does sir david mean by a ‘moment of crisis‘? this graph shows the annual mean land temperature since the 1800s, our world is getting warmer and warmer. and this graph shows how much worse the problem will get if countries do not cut emissions. here's more from our global science correspondent rebecca morelle. once it is gone, it isjust gone. our planet is heating up fast.

causing long—term changes to our weather. that is basically what we are talking about when we say climate change. it was overwhelmingly terrifying. the damage is immense. it's been linked to a year of extremes, from australia's devastating fires to the torrential rains in indonesia and europe's record—breaking temperatures. some say that 2020 is our last real chance to tackle the problem. but what has brought us to this point? throughout the earth's history, the temperature has changed but the record rise now is down to us. humans. from the 19th century, coal, oil and gas, known as fossil fuels, have transformed the way we live. but it was only later that we discover the problems they cause and by then we had tvs, planes, cars, and microwaves. burning fossil fuels releases gases that trap heat from the sun, that is why they're known as greenhouse gases. carbon dioxide is one of the major offenders. there is now more of it in the atmosphere then there has been for millions of years. sir david attenborough has also been

speaking about the bushfires that are raging across australia. as i speak, southeast australia is on fire. why? because the temperatures of the earth have been increasing. that is a major national, international catastrophe. and to say it is nothing to do with the climate, it is palpable nonsense. and who has been affecting the climate? we have. we know that perfectly well. so we have to realise that this is not playing games. this is notjust having nice little debates and arguments and then coming away with a compromise. this is an urgent problem that has to be solved. as the world grapples to find an adequate response to climate change, many countries look at china. remember this from australia's prime minister at the weekend. we could close down every

single power generation facility in the country, and those emissions would be taken up by china in about nine days. now we discuss the merits of mr morrison's ‘there‘s no point taking action because china emits a lot more than us‘ argument. in particular because china imports millions of tonnes of australian thermal coal — which then produces some of china's emissions. but scott morrison's right that china does emit an awful lot. this bbc graph shows the world's top emitters of carbon dioxide per year. china is top by far. that's a huge challenge no doubt — sir david attenborough sees potential too. if china become leader of world opinion, then that is a huge slab of the human population. if they will take major steps to control the carbon emissions, that is a huge advance and i hope to goodness it will happen,

because if it does, i'm sure it would be easier for other nations to fall into line. so what chance is there of getting china's emissions down? here's our asia pacific editor michael bristow on that. china is the world second—biggest economy. it has 1.4 billion people and accounts for more than a quarter of all greenhouse gas emissions. anything china does will have a major effect on global warming and without china, the world will have little chance of tackling and controlling climate change. traditionally, china has done pretty well in terms of emissions, it is a well‘s biggest developer of renewable energies and over the last few years, greenhouse gas emissions did plateau. recently, they have started to rise again. china slowing economy has led to the government putting a lot more money into steel and cement, those industries that produce a lot of greenhouse gases.

china quite rightly says it is on target to meet its commitments according to the paris agreement. those commitments were to buy 2030 have a fifth of its energy output and renewable sources and to have a submission speak by that time but experts say that is simply not enough if we will tackle climate change. stay with us on outside source — still to come... more on climate change — microsoft pledges to remove from the enviroment all the carbon it has emitted since the company was founded more than 40 years ago. one of the frontrunners for the labour leadership, sir keir stamer says his party risks "missing the facts" if it only focuses on its most recent election defeat— pointing out labour has now lost four times in a row. sir keir backed remaining in the eu, and was part responsible for labour's rather confused message on brexit — but says he is the man

to pull the party together. what i did, along with hundreds of thousands of our members, was to go out and campaign with energy and positivity, but in the end, people didn't have trust in us. partly that was to do with the leadership, rightly or wrongly. partly that was to do with brexit, anti—semitism came up and the overload of the manifesto. all of these things came up. we need to restore that trust. and if we only look at the 2019 election, we are missing the fact that we have lost four in a row. this is outside source live from the bbc newsroom. our lead story is? the impeachment trial of president trump has formally begun — the charges have been read out in the senate —

and the presiding judge has been sworn in. russia's parliament has voted overwhelmingly to confirm russia's new prime minister — mikhail mishustin. this is earlier. as the vote went through. mr mishustin was picked by president putin — and this is part of a major kremlin shake—up. this all happened after president putin made a speech yesterday announcing constitutional changes which weaken the presidency. that may sound counter—productive — but he can only serve as president til 2024 — that's the end of his second term. beyond then if he wants to stay in power, a weaker president will be no bad thing. pro—opposition commentator andrey malgin... i never doubted that putin was a cynical rascal, but today, he simply went ahead and announced his plan for staying on to rule the country for ever. usually such things are planned and carried out in secret."

this image that's currently being heavily on twitter is making a similar point. there's a picture of the president though an old age filter from that russian app which went viral last year. now vladimir putin says this isn't to do with him staying in power — the constitutional changes are for the benefit of all russians. let's see how the local press is reacting. this is a pro—kremlin tabloid. there's putin — under the headline "how can we defeat poverty." the new pm just makes it in. while this business paper — which isn't particularly loyal to the kremlin — features the new pm saying he was chosen because of his successes in his previous role as head of the tax office. and this is state tv.

you can see the new prime minister being featured there. that's being played continuously on state media — the new prime minister is being hailed for his tax collection system. adam robinson follows the russian media for bbc monitoring. it is kind of a 2—story depending on who you watch or listen to or read. the state media or independent commentators. an proposition media. the state media say this is a revolution. this exchange and to portray the new prime minister as a figure who will push the transformational change. they are having this stretching a bit to try and portray that because he has this slightly great cv, very much a technocrat come a long history of service and taxes, the tax service, but they are using this to say he transforms the tax service while he was in power and turned it from this rusty old institution and to a world beating tech service. and if the world. for mr putin is there any acknowledgement from ctv this could

be an effort for him to maintain power and influence beyond his next term? no, that has not been mentioned at all. they are not really speculating that much about what he would do. they are very much focus on the announcements about welfare that he made and that this would bring changes to russians last and that this will raise living standards government through the sort of maternity benefits and child benefits he announced. microsoft has announced two ambitious climate change targets today. firstly it plans to become carbon negative by 2030. that means removing more carbon from the environment than it emits. here's the compa ny‘s president on the second pledge. by by the year 2050 we will remove from the environment all of the carbon that microsoft has emitted historically. either directly or for our use of electricity since the company was founded in 1975. it is a bold set of goals but i think even more importantly it is really a

required in detail set of plans. we have spent many months working on this and we shared with people today. michelle fleury is in new york. how is microsoft going to meet these targets ? how is microsoft going to meet these targets? these are incredibly come a statement from this company. here's why. it is notjust trying to reduce carbon emissions, it is talking about going carbon negative. put to put this in context for you before i get to how they would do it, it is joining ikea and a handful of companies that are promising essentially to remove all the emissions the company has ever released. how will he do this? as well as part of its daily business practice, forcing employees to think about emissions when they make decisions, the company says it is going to try and also move things across its entire supply chain. they are not thinking about reducing business, but they are looking at how do we power our data centres

because those obviously emit a lot of emissions. that is why they are trying to buy 100% renewable energy and the intend to rely on electric vehicles going forward. this will ta ke vehicles going forward. this will take time, but we have some reaction with the extension rebellion group in the uk activist they're basically saying this is an important step in the right direction. quickly, microsoft will say it is doing this because it is the right thing to do but is there a business case for it as well? what was interesting when brian smith of the presentation, he showed how carbon emissions and gdp, all of this was beginning to align together and so companies are not waiting for governments to act but are saying economic motives and a profit motive for this. it is worth pointing out microsoft employees protested against the company in septemberfor work protested against the company in september for work with oil giant saying it wasn't doing enough. thank you, michelle. speakto saying it wasn't doing enough. thank you, michelle. speak to you next week. next we have brexit cast.

good evening. news the limit for quality across europe. want chill continues in canada and storm on the way to fiji, but first let's head to australia. this meant in the headlines for a few weeks now. cooler conditions and the south and the east and the weather front bringing outbreaks of rain to take us bringing outbreaks of rain to take us to the end of the week. anywhere from northwards, the most torrential of the rent will be northern parts of the rent will be northern parts of new south wales all the way through eastern queensland and that will continue into this weekend. the storms can be pretty vicious where they occur in some damaging winds and large hale, potentialfor flooding. and of course with thunderstorms mixed in. lightning strikes set off further storms but things are cooler, staying that way in city until the first part of next week. cumbria and melbourne into the start of next week will see some

rain arrive again. just a short hop away from australia and the south pacific, this world of cloud here. this is a developing tropical cyclone, they can impact on fiji toward sa m oa cyclone, they can impact on fiji toward samoa going to the next few days. strengthening winds can bring pretty rough damaging sees, torrential rain storms as well and of course those winds which could cause an issue. away from that, less airto canada cause an issue. away from that, less air to canada where we have talked about the chill. calgary today, winnipeg at —25 today. bitterly cold and the british air pushing his way southwards now across the us and towards the east. we will see things which over the next few days in the cold air focusing towards eastern areas and turning milder but it is in the west where the cold air has beenin in the west where the cold air has been in place, we see weather system pushing off of the pacific, three feet of snow falling in parts of british columbia. a lot of snow in california as well over some areas on thursday night. that will work is what use swears, joining forces with

developing weather systems do the planes, some parts of central canada and the midwest come huge amounts of disruptive snowfall, torrential rainfall on the southern flicker of could sponsor pretty damaging winds and flooding and the cold air will be setting and across eastern parts of the us as we finish the weekend and into next week. you are now, a rather murky scene in krakow over the past few days. —— in europe now. air pollution has been an issue. this is an area of high pressure. temperatures have been above average for the time of the year. we will see things clear air out as we go into the weekend thanks to this weather system which will bring outbreaks of rain, gusty winds and from the west come and across the mountains of norway into the western alps become a good dose of snowfall to ta ke alps become a good dose of snowfall to take us into the start of the weekend. still some mist and fog problem for the ease and the mediterranean looking quieter, but that weather system works is what use words as we go through this weekend and emotional to come on the alps. in the uk, no snow but a bit

ofa alps. in the uk, no snow but a bit of a respray from the wind in the rain this weekend. more details in half an hour. now it's time for brexitcast. website brexitcast. .. brexitcast... from the bbc. danny dyer: no-one's got a (bleep) clue what brexit is! donald trump: brexit is, errr... dominic raab: i hadn't quite understood the full extent of this. we are particularly reliant on the dover—calais crossing. keir starmer: this election blew away the argument for a second referendum. boris johnson: i urge everyone to find closure. let the healing begin. ursula von der leyen: i am sorry. we will miss you. yanis varoufakis: a process which i can only describe as a dog's brexit. this is katia adler and adam and brussels and chris in westminster. picking up on last week, the news,

compared to what it was, has lost its capacity to excite but there are still stuff to get into if we return to the tradition of brexitcast delighting in the nuance and detail. huge news and other parts of the news landscape. but from your end, although he set out in london, something familiar but important from one of the people who will matter in the next 12 months? this is phil hogan, known as big phil! he is phil hogan, known as big phil! he is super tall, about a foot six! he has other attributes that she is irish, he was the agricultural commissioner in the last commission and is now the trade commissioner. he isa and is now the trade commissioner. he is a big character, very forceful. and he will be involved in the trade negotiations and we think with the uk although not clear and he was actually in america talking to doing an interview with peter

mandelson at a conference
