tonight at ten, the world has now reached the point of climate change crisis. that's the stark warning from sir david attenborough. the effects of global warning, he said, make immediate action vital, action that countries have been putting off for year after year. the moment of crisis has come. we can no longer pick prevaricate. as i speak, south—east australia is on fire. we'll bring you more from his bbc news interview and also look at how australia is coping with the bushfires there. also tonight... donald] trump has abused the powers of the presidency. donald trump ‘s impeachment trial gets under way in the senate. the president denounces it as a hoax.

prince harry posts this, his only footage of his first public engagement since his announcement of stepping back from royal duties. cocaine —related deaths are at record levels in britain. we have a special report on the soaring use of the drug. and victory from the jaws of defeat, how this little book shop in hampshire went from no sales to global sales. and coming up on sportsday on bbc news — ben stokes plays his part for england once again, on day one of the third test against south africa. good evening. after this week's confirmation that the last decade was the hottest on record, sir david

attenborough has warned that the moment of crisis has arrived for the world over climate change. in some of his strongest comments yet, sir david said that countries have been dodging their commitments for too long and that every year that passed made it more and more difficult to achieve the necessary change. he added that it was nonsense to suggest the bushfires in australia we re suggest the bushfires in australia were nothing to do with climate change. we'll have more from australia in a moment but first, here's our science editor, david shukman. a stunning view of our fragile planet, the blaze of lights evidence of the many impacts we're having on the globe. whole forests in madagascar cut down to create farmland. in germany, huge mines gouging out coal for power stations. cities sprawling into natural habitats, and all this a scale so large that it's even changing the climate, and the world now faces crucial decisions. the moment of crisis has come. sir david attenborough tells me time is running out. as i speak, south—east

australia is on fire. why? because the temperatures of the earth have been increasing. that is a major international catastrophe, and to say it's nothing to do with the climate is palpably nonsense. and who has been affecting the climate? we have. we know that perfectly well. the biggest cause of rising temperatures is well known. burning fuels like coal gives off gases that heat the planet, and more of this keeps happening. and we're all involved in this. nearly every home in the uk is heated by a gas boiler, and they also give off carbon dioxide. the result, in a warming world, is that the level of the oceans keeps rising, which means that flooding is set to become more frequent. and life in many countries, including parts of britain, may change as well, from scenes that we're all familiar with to much more extreme heatwaves

and potentially much drier landscapes like this, the mediterranean section of the eden project here in cornwall. so a glimpse of what may be in store for some areas. the climate is already looking different. and it's striking how, over the last 170 years, the average global temperature has changed. relatively cool early on, then getting warmer and warmer until the present day. for elizabeth thompson and anyone younger than 35, temperatures have been rising for their entire lives. from when she was born in 1989, every single month as she has grown up has been warmer than the long—term average. she hopes the rise will stop, but fears more severe heatwaves if it doesn't. if we're seeing more heatwaves and more extreme events like this and they're becoming more frequent, then i'm worried that when i'm older, we won't have the capacity to deal with those, especially

if they're even worse than what we've previously experienced. but i am still optimistic because we are seeing a lot of action now notjust on an individual level, but at the local, national and global. one reason she is optimistic is the surge of climate protests by young people. and sir david attenborough is inspired by them as well. there has been a huge change in public opinion. people can see the problem. particularly young people can see the problem. and that must force governments to take action. flashes of lightning in a warming world. it's a key year for negotiations on the future of the climate, and many hope it will be a turning point. david shukman, bbc news. well, sir david talked there about the wildfires that have devastated parts of australia. hundreds are still burning, mainly across the south—east of the country, where the authorities are desperately trying

to prevent them from spreading further. there are at least eight weeks of the bushfire season still ahead. clive myrie joined weeks of the bushfire season still ahead. clive myriejoined one fire crew in new south wales. the fires eating this land have burnt from the mountains to the sea. in between, eucalyptus, bottlebrush and pine. it's hard, but save the forest and you save australia. man is having a terrible time trying to stop what mother nature is doing to us. but this is definitely the worst fire season that i've seen and most of my colleagues will have ever seen. you see how the wind really influences what the fire's doing. zeb is charged with protecting 2.5 million acres of forest in the state of new south wales. several villages and towns are just a few miles away, right in the path of oncoming flames. it wouldn't be that active if it wasn't so windy.

zeb‘s team has already cleared some scrub, taking away fuel for the fire, but wisps of smoke are creeping through like water under a door. how long before the main firefront appears? it's been a long bushfire season for zeb and his crew. it's 4.36 in the afternoon and we can't see anything. days bizarre when smoke has blocked out the light of the sun. and frightening days when people died. but time's running out to stop the latest blaze spreading. more of the forest needs to be cleared to create a big enough firebreak. it's a real shame to have to do this. but these fires this season are not behaving normally. and if we don't start putting these breaks in to stop it, more fires are just going to burn. zeb‘s team deliberately ignites

part of the forest, destroying fuel for the oncoming monster. well, this fire was litjust a couple of minutes ago and you can see how it has taken hold, blown by these really strong winds. and these are the conditions that the authorities have been having to deal with during this appalling bushfire season. night and day, fires are being deliberately lit by emergency crews. this, the neighbouring state of victoria. but are the latest attempts to hold back the firefront working? so that's about the last of it, eh? it's all lit up now. good job. doesn't take much, does it? well done. that's got that contained anyway. zeb and his team have won this battle, but is australia winning the war? well, we're having a go and we're steering them and at times we can have small wins. we bite off small pieces.

so we're not winning, but we're not losing either. clive myrie, bbc news, in southeast australia. well, we can talk now to our science editor david shukman, who is in glasgow, whether un's international conference on climate change will be held at the end of the year. what are the chances of that conference producing anything meaningful is yellow welcome as we've been hearing, sir david attenborough and of course many others are passionately hoping that this summit this year will see some kind of turning of the tide on climate change, and that's because it's at this summit the countries of the world a re this summit the countries of the world are meant to come up with new, tougher targets for cutting emissions of gases that are heating the planet. that's really matters because at the moment globally those emissions are still going up, when scientists couldn't be clearer that they need to full dramatically. it has to be said that there is not a great track record with these summits. the most recent one, in

madrid last month, ended with key issues being kicked down the road, so issues being kicked down the road, so the burden will really be on the british government in the coming months to try to get things back on track was white and david, there's big news tonight about a movement by microsoft? this is extraordinary, from the software giant, not to come out with some distant target for cutting emissions like many other companies, but actually to say that by2030, companies, but actually to say that by 2030, in ten years' time, it wa nts to by 2030, in ten years' time, it wants to be notjust carbon neutral but here's a new phrase, carbon negative, which means pulling in carbon dioxide from the atmosphere. now, quite how they are going to do that and how anyone might check remains to be seen, but imagine a flurry of announcements from major global companies of that kind in the coming months, that could possibly, conceivably, make a difference to how things turn out at the summit here in glasgow. many thanks, david shukman, our science editor in

glasgow. donald trump has been formally accused of abuse of power and obstruction of congress in charges read out in the us senate. it marks the start of his impeachment trial by the upper chamber‘s 100 senators, who have been sworn in as jurors. if found guilty the president will be dismissed from office. mr trump is accused of secretly putting pressure on ukraine to dig up dirt on a political rival and then obstructing the investigation, and in new evidence on aide who was involved had said president trump knew exactly what was going on. our north america editorjon sopel reports now from washington. across the marbled floors of congress the statues from a bygone age looking down on the team that will leave the prosecution of donald jtrump. will leave the prosecution of donald j trump. they carry under their arms the files contain the articles of impeachment. the serjeant at arms will make the proclamation. all

persons are commanded to keep silent oi'i persons are commanded to keep silent on pain of imprisonment. the language may come from a more genteel era but don't be gold, this isa genteel era but don't be gold, this is a 21st—century partisan scrap. house resolution 755, impeaching donald john trump, president of the united states, for high crimes and misdemeanours. the trial will be presided over by this man, john roberts, the chiefjustice of the supreme court. and all 100 senators, thejury, had to supreme court. and all 100 senators, the jury, had to swear this oath. do you solemnly swear that in all things appertaining to the trial of the impeachment of donald john trump, president of the united states, now pending, you will do impartial justice states, now pending, you will do impartialjustice according to the constitution and laws, so help you god? ironic, given the fact it seems every senator has already made up his or her mind and will vote along strict party lines, but donald trump isn't impressed by any of it. strict party lines, but donald trump isn't impressed by any of itm will go very quickly, it's a hoax,

it's a hoax, everybody knows that. it's a complete hoax. but last night, an 11th hour bombshell interview from a man who had been at the forefront of outfits to strong—arm the ukrainian leader to launch a corruption investigation into the former vice president, joe biden, the central issue of this impeachment. lev parnas, who had been working alongside the president's personal lawyer, accused donald trump of being a liar. 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 01’ without the consent of rudy giuliani or the president. donald trump says he scarcely knows who lev parnas is and the white house adds that this isa man and the white house adds that this is a man facing criminal charges and isn't to be believed. but that's a slightly awkward defence. it was certainly trusted enough to meet president zelensky en donald trump ‘s behalf and his lawyer to communicate what it was that the white house wanted. the trial proper

will start next tuesday and the fight that's about when siew will be historic, but in keeping with the times it will also be ugly. jon sopel times it will also be ugly. jon sopel, bbc news, washington. prince harry has appeared at his first royal engagement since he and his wife meghan announced they would be stepping back from their roles as senior royals. the prince was at buckingham palace to host the draw for next year's rugby league world cup. nicholas witchell has more. nicholas witchell has more. was this harry's way of saying farewell? there he is on the sussex royal instagram account tonight. the music, the stone roses and a song which includes the lyrics "i'd like to leave the country for a month of sundays." he was at buckingham palace. in the palace gardens he had been in his element, talking to young people about sport, rugby to be precise, and those who were with harry said he was relaxed, authentic and engaged. but you didn't need to be told that, you could see it in his face his actions.

face and his actions. harry, how are talks going about the future? reporters tried to ask questions about his future. unsurprisingly they were ignored. the occasion was the draw for the 2021 rugby league world cup to be staged in england. harry was being harry. well done. the old harry as someone said. he was there as patron of the rugby league, that is one of those things that the royals do. and something harry has done is highlight mental illness in sport. it's a cause which matters to him. the perception of rugby league is that you need to be tough, you can't show your feelings and you have to grin and bear it. but something like the mental fitness charter will help us make real progress in getting rid of the stigma associated with mental illness. by this time next week harry will probably be several thousand miles away, beginning a somewhat semi—detached royal life with his wife. and the veil is fantastic.

and the beard is fantastic. there will be fewer occasions like this, his easy charm will be missed. i have seen some beards in my time. nicholas witchell, bbc news. a record number of people in england and wales have been cautioned or convicted for carrying knives according to the latest figures. the ministry ofjustice says more than 14,000 ministry ofjustice says more than 111,000 cases were dealt with by police and the courts in the year to the end of september. the government has said it wants to make tackling knife crime a priority. sepsis or blood poisoning now kills more people around the world each year than cancer, according to a major international study. the discovery came after research put together globalfigures for the came after research put together global figures for the first time. 0ur health editor hugh pym is here for us now. startling statistics. 0ur health editor hugh pym is here for us now. startling statisticsm has been dubbed the hidden killer because it is hard to detect. it is

when the immune system goes into overdrive and starts attacking the body's organs. now we have a global study on sepsis cases. it shows in 2017 there were nearly 50 million cases globally and 11 million deaths with sepsis worldwide, more than cancer. here are some examples from leading economies. in japan cancer. here are some examples from leading economies. injapan there we re leading economies. injapan there were just over 7a deaths per 100,000, slightly more than in the uk where it was just under 72. but that was well above france where the figure wasjust that was well above france where the figure was just under 57, and a that was well above france where the figure wasjust under 57, and a lot more than in australia at 36 deaths per 100,000. there are questions about the precise comparability about the precise comparability about countries' data and it is true, but it raises questions about how sepsis is detected in the nhs and other health systems. the sepsis trust, which has campaigned for more awareness says it is certainly true that a lot of these deaths are

preve nta ble that a lot of these deaths are preventable and a lot of urgent action is needed to tackle this deadly condition. one of the candidates for the labour leadership, sir keir starmer, says his party's problem should not be blamed on than 2019 general election alone because it had been using support in its heartlands for years. in the first of a series of interviews with the labour leadership candidates he has been speaking to laura kuenssberg in his north london constituency. i think what labour needs is a leader who is capable of restoring trust in the labour party as a force for good and a force for change. he is the mps' favourite, but it is labour's members who will choose the next leader, the contest after a stinging defeat. you were, though, a very prominent part ofjeremy corbyn's team and it went down in a terrible defeat, so you were part of the problem. why should you be part of the solution? there are many reasons we lost the election in 2019, but we've lost four, we've lost four elections in a row

and therefore identifying a particular thing in this election isn't going to help. but on two big issues, the brexit plan, you were in charge of that, and anti—semitism, racism against jewish people that the party didn't take seriously enough, you say that now, but you were in the room at the top table. we need to understand what happened. as i said, i didn't meet anybody on the election trail who said, "everything is fine, i don't want anything to change." people were crying out for change, theyjust didn't believe our party was the party that could deliver that change. we need to unify the party and i think i can do that. we spent far too much time fighting ourselves and not fighting the tories. factions have been there in the labour party, they've got to go. i'm very sympathetic to the argument we've lost our heartlands, we've got to get them back. is this north london lawyer labour‘s answer? the party has lost touch with so many voters and so much of what was natural territory. it is easy to talk ideology, less so real life. you say you are a moral socialist.

what does that mean in practice? what i see is inequality everywhere and you see it in every community, you will see it in these communities here, and i don'tjust mean wealth and income, i mean influence and halth. i mean influence and health. and i've never walked past those sorts of wrongs and injustices. if i was to ask you if your politics are closer to the politics of tony blair, or the politics ofjeremy corbyn, where would you put yourself on that spectrum? look, tony blair was addressing problems a quarter of a century ago and jeremy corbyn took us through four really difficult years. but it's notjust about the period of time, it's about the spectrum within the labour party. where would you put yourself on it? i want to lead a labour party that is trusted enough to bring about fundamental change. i don't need somebody else's name or a badge in order to do that. what we forget in all of this is that all the labour party, all the teams of leaders,

they have to do it for the circumstances as they are. 0ne labour party member told us on monday this week that keir starmer is very sensible, but sensible is not very appealing. do you get that? throughout this leadership campaign you are going to get different views from everybody on all of the cabinet and i completely accept that. you need someone who is able to, as it were, be capable of being respected and seen as someone who is trustable and trusted across the whole of the united kingdom. the risk for sir keir perhaps, he may represent neither continuity nor big change, not clear in a detailed way yet what he plans to offer instead. laura kuenssberg, bbc news. people taking cocaine are putting increasing pressure on the nhs in england, according to new figures. data compiled for bbc news shows that since 2014—15 a number of

hospital admissions for cocaine poisoning has increased by 76% to over 4000. hospital poisoning has increased by 76% to over4000. hospitaladmissions poisoning has increased by 76% to over 4000. hospital admissions for mental disorders caused by cocaine went up by 70% to 15,500 over the same period. cocaine —related deaths are also at record levels, doubling in england and wales and tripling in scotla nd in england and wales and tripling in scotland since 2015. here is our social affairs correspondent, michael buchanan. to warn you, there are distressing images in his report. preventing cocaine from getting here is heavy work. the border force check containers, gather intelligence, seize drugs. though not this time. yet cocaine has never been more available. do you ever get impressed with some of the thinking that goes into the smuggling? absolutely. yeah, that's part of the challenge that we face as a border force is trying to stay one step ahead of those smuggling gangs. getting coke has never been a problem for lewis. most club toilets there's someone doing it. five o'clock in the afternoon,

there's people doing it in the toilets. it's everywhere. the 25—year—old started taking cocaine around six years ago after a friend offered him some. it became a habit. i basically had a heart attack, like, not...so my friends a nurse and she had a blood pressure thing on my arm and was taking my pulse. she was just like whispering, "call an ambulance." yeah, i'mjust like... my heart pounding out my chest. today, lewis only takes cocaine occasionally. the drugs appeal waned. the worst paranoia i've had in my life. i'd be sat by the window at night, hear a car pull up, like, looking over my shoulder. but more people than ever are using cocaine, enticed by different strands of varying purity. there's prop, expensive cocaine for around £100 a gram, down to as little as £30 a gram for so—called council coke.

from the age of 15, we've supported people to try and help them address their cocaine use. in lanarkshire drugs worker eddie baggy is seeing ever younger people developing a cocaine problem. it's easier to buy than alcohol. you don't need to walk into a shop to get it, and you use digital platforms to get as well, which young people are very familiar with. so online, snapchat, whatsapp, stuff like that. i remember sleeping in a telephone box, homeless, that's where drink and drugs took me. colin mcgowan is chief executive of hamilton accies football club but his passion is helping teenagers steer clear of drugs, with the help of former footballer colin mcnair. i was playing at ibrox in front of 50,000, 60,000 fans. colin discusses his footballing career to engage audiences, but he shows them his legs to emphasize his real message — the impact

of a two—decade—long drug addiction. he lost everything. people that are not in addiction and not experimented with drugs, they can't understand it. "you actually threw all that away?" i didn't throw it away — caught up in addiction, you've not got a choice. your choices are taken from you. that's how strong and powerful cocaine is. cocaine is no longer the preserve of the rich. it's now an everyday drug in britain, readily available, widely consumed, increasingly destructive. scotla nd scotland is expected to become the first country in europe to ban heading in youth football. the scottish fa is considering banning for the under 12 is after a study found former footballers were three times as likely to die of degenerative brain diseases like dementia than the rest of the population. but more research is needed. but more research is needed. "tumbleweed" — that's what the owner

of this antique and second—hand bookshop in hampshire tweeted in desperation this week. he hadn't sold a single book all day — the first time ever in its 100—year history, he thought. so he asked for help. and he got it as his tweet went viral and orders started coming in from all over the world, as duncan kennedy explains. once upon a time, there was an old book shop. but this isn't a fairy tale. it really exists. where quaint meets quirky. but last tuesday, there were no customers. not one. which led the shop to put out this forlorn tweet. it read... "tumbleweed, not a single book sold today, £0, we think it may be the first time ever." the message was spotted by best—selling author neil gaiman, who retweeted it to his 2.7 million followers. the orders then came flooding in.

somebody from inverness rung up and said they want to spend £10. they didn't care which book. somebody from california wants to donate $50. and it is just the love for books. you cannot beat a book. they become like oold friends. in a shop where weird meets words, new customers have been arriving all day. a second—hand book shop, an antiquarian book shop like this is a treasure trove of amazing things. it is the kind of shop that has every kind of title. and although the likes of oscar wilde wouldn't have known much about twitter, this shop has gone from having just over 1000 followers, three days ago, to more than 11,000 followers today. with e—books and amazon around, independent sellers won't always be busy on a wet january afternoon, but this one, like all the best books, really has captured the imagination. duncan kennedy, bbc news, in petersfield. now on bbc one, time for the news where you are.

have a very good night. hello and welcome to sportsday. coming up on the programme, and under beaten stand from bed so sent all he pope is england an edge in day one of the first test match in south africa. from bad saracens face relegation from the premiership if they have been found to breach the salary cap this season. and coco goff will face venus williams at the grand slam again as organisers of the australian open will not be affected despite concerns over the air

quality. —— organisers say that the are showing 0pen will not be affected. welcome to the programme, thanks forjoining us. let's start with the cricket and the search for test consistency for england. all eyes are on them in port elizabeth for the start of the third test today. they closed on 224—4 with man of the moment ben stokes and ollie pope at the crease. 0ur cricket correspondent jonathan agnew was watching. south africa's captain could foresee many scenarios when this test began. here's what he saw. england batting with assurance. they reached lunch without losing a wicket. probably

and simply, the signs were encouraging. but south africa set a trap specifically, a fielder right there. coffer 36, crowley did not see that but it didn't stop them from falling for. going for 34. the reaction to one of the highlights. the calmness of the port was with kos was sometimes smashed by the tranquility of the cricket. slow going, not vrbata. anytime a fast bowler does that, it's a triumph. but he had just dismissed england's captain, so drain everyjob of celebration. every drop. it's a tight match, a tight serious but all he pope and ben stokes will both resume but in once a narrative are, both could take control. joe wilson,
