the world is facing a moment of crisis over climate change — the warning from sir david attenborough. forest fires, melting ice, drought, flooding — sir david says the world can no longer wait. action is needed now. the moment of crisis has come. we can no longer prevaricate. as i speak, south—east australia is on fire. in australia, firefighters forced to cut down trees to take away fuel for the fires as the forests burn. well, this fire was lit a couple of minutes ago and you can see also on the programme tonight... prince harry walks out to face the cameras on what may well be his last royal engagement for a while — posting this, his own footage, on social media. just beyond there as the british

library. what went wrong for labour at the last election? one of the candidates for the party's leadership, sir keir starmer, says they need to look back a lot further to find the answers. cocaine—related deaths are at record levels in britain — we have a special report on the soaring use of the drug. and not a single book sold all day for the first time in its history — how this bookshop‘s fortunes were suddenly turned round by one message on twitter. and coming up on bbc news, good repair work from ben stokes. and ollie pope gives england the edge on day one of the first test in south africa. good evening and welcome to the bbc news at six. sir david attenborough says a moment of crisis has arrived for the world over climate change and action is needed.

in some of his strongest comments yet, sir david says we have been putting matters off for too long. his warning comes as bbc news begins a year of special coverage on the subject of climate change ahead of the un's international conference in glasgow at the end of the year. 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 on 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 have 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. in australia, hundreds of bushfires continue to burn. so much forest has already been devastated, but now firefighters are reluctantly having to cut down even more trees to try to create fire breaks and take away the fuel for the blazes. clive myrie joined 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. a nearby backburning. 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. our science editor david shukman is in glasgow. clearly the issue is

on everyone‘s mind? we heard sir david attenborough‘s morning. could we be about to see a turning point? he certainly hope so. he regards this as a critical year in discussions about climate change. not only is the science of climate change becoming clearer, but the demands, especially from younger people, are becoming stronger and later this year here in glasgow at the conference centre behind me, there will be what could be the largest gathering of world leaders ever on british soilfor a united nations summit on climate change. and governments gathering there are meant to come out with new, tougher targets for cutting the emissions of the gases heating the planet. but at the gases heating the planet. but at the moment, those emissions are still going up rather than down. tell us about the proposal is that the government has come up with for farmers in england? yes, the government has come up with a radical plan. some say it is

potentially the biggest change for farmers in a generation, where they will be rewarded not for owning land, but for looking after it environmentally, to encourage them to use the soil and the trees to store carbon. just one of many measures to try to tackle climate change. but the details of that have yet to come out. david shukman in glasgow, thank you. and you can find out more on the bbc news website and app at bbc.co.uk. and app at bbc.co.uk/news. prince harry has carried out his first royal engagement since he and his wife meghan announced last week that they would be "stepping back" from their roles as senior royals. prince harry hosted the draw for next year's rugby league world cup at buckingham palace. our royal correspondent nicholas witchell has more. was this harry's way of saying farewell? the music the stone roses and a song that includes the lyrics,

i would like to leave the country for a month of sundays. he was at buckingham palace. in the palace gardens, he has been in his element, talking to young people about sport, by, talking to young people about sport, rugby, to be precise. and those who we re 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 and actions. 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, someone said. he was there as patron of the rugby league. that's 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.

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. there will be fewer occasions like this. his easy charm will be missed. nicholas witchell, bbc news. the most comprehensive study of sepsis around the world has found sepsis is triggered when the immune system's response to an infection is out of balance and can become life—threatening. the figures, from the university of washington, are twice as high as previous estimates. the problem is most acute in sub—saharan africa. one of the candidates for the labour leadership, sir keir starmer, has warned that after losing four elections in a row

his party risks "missing the facts" if it only looks at what went wrong in the last election. he said the factions in the labour party had "got to go" and that he could pull the party together and restore trust in it. as part of our series of interviews with the labour leadership candidates, he's been speaking to the bbc‘s political editor 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 is a force for good and a force for change. but you were a 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 have lost four. we have 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 againstjewish people, that, and anti—semitism, racism against jewish people, that that, and anti—semitism, racism againstjewish 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. i didn't meet anybody on the election trail who said everything is fine, i don't wa nt 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, andi change. we need to unify the party, and i think i can do that. we have spent far too much time fighting ourselves and not fighting the tories. factions have been in the labour party. they have got to go. i went to leeds university. then i went to leeds university. then i went to leeds university. then i went to oxford university, studying law. i then became a barrister and then became director of public prosecutions was that came into parliament in 2015. i, keir starmer, do declare... only five short years ago, and it seems like somebody has

shoved 50 years' worth of change into those five years. you say you area into those five years. you say you are a moral socialist. what does that mean in practice?” are a moral socialist. what does that mean in practice? i see inequality everywhere. you see it in every community. you will see it in these communities here, and i don't just mean wealth and income, i mean influence and help. i have never walked past those sorts of wrongs and injustices. if i were to ask if your politics are closer to the politics of tony blair or the politics of tony blair or the politics of tony blair or the politics ofjeremy corbyn, where would you put yourself that spectrum? look, tony blair was addressing problems a quarter of a century ago. and jeremy corbyn took us century ago. and jeremy corbyn took us through more really difficult yea rs. us through more really difficult years. but it's notjust about the period of time, it's about the spectrum within the labour party. period of time, it's about the spectrum within the labour partym is, but 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 badge to do that. what we forget in all this is that all the leaders in

the labour party, all the teams of leaders, they have to do it for the circumstances as they are. one labour party member told us on monday that keir starmer is sensible, but sensible is not very appealing. you get that? throughout this leadership campaign, you will get different views from everybody on all of the candidates, and i com pletely on all of the candidates, 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 united kingdom. some people think you're out for a decade now. it is a mountain to climb, but i'm determined to claim that mountain. laura kuenssberg, bbc news. the time isjust the time is just after quarter past six. our top story this evening... the world is facing a moment of crisis over climate change — a warning from sir david attenborough. and children are set to be banned from heading footballs during training by the scottish fa.

and coming up on sportsday on bbc news, 15—year—old coco gauff will face venus williams at the australian open, as organisers say the tournament will start on time despite concerns about air quality. cocaine—related deaths are at record levels in britain — they've doubled in england and wales and tripled in scotland since 2015. at the same time more and more people are ending up in hosptial after taking the drug and it's putting a lot of pressure on the nhs. according to new figures for england, the number of hospital admissions for cocaine poisoning since 2015 has increased from 2,500 to more than 4,000 — that is a 76% rise. hospital admissions for mental disorders caused by cocaine increased from 9,000 to 15,500 over the same period — up 70%. our social affairs correspondent michael buchanan reports on britain's soaring use of the drug. just to warn you, there are some

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 bradwell. 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. this 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 buggy 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 to 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. "he actually threw all it 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. michael buchanan, bbc news. tomorrow michael reports from colombia, where cocaine production has reached record levels. 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 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. the nhs is calling on the gambling industry to end aggressive advertising that it says fuel dangerous addiction. the head of the nhs in england said officers were stopping people escaping a vicious gambling cycle. the official body

said bookies had already taken steps to protect vulnerable customers. children in scotland could be banned from heading footballs during training because of fears over the links to dementia. it's understood the scottish fa will introduce the changes later this month after a report found that former players have a higher risk of dying from the disease. the english football association say more research is needed. here's our sports news correspondent, chris mclaughlin. on the outskirts of glasgow, children training. in a few weeks, these players and others under the age of 12 across scotland will be told no headers. it's all because of a study that found former players are three and a half times more likely to die from dementia. when you are older you can do it but maybe not when you are younger because you might get brain... because they are hard balls. at that age they don't really need to headed the ball, the ball should be played

oi'i the ball, the ball should be played on the ground. this confirmed what many people feared, there is a link between dementia and football. what the findings didn't show is why but the findings didn't show is why but the scottish fa are taking no chances. we can't wait on the evidence one way or the other on heading, we need to take pragmatic steps and that's largely to try to reduce the overall burden and number of times that young players head. that was a massive part of my game. managers bought me because i could head the ball. it's the correct decision if ultimately it's going to stop players getting illnesses as they get older. the family of the former west brom striker geoff postel who died of dementia in 2002 have been campaigning for football authorities to do more. but on heading the fa have said this...

tonight at a training session in north london, reaction to the news that for now things will change in scotla nd that for now things will change in scotland only. i watched enough kids games to see that during the course of the game they don't header the ball that much. i think it is a good thing and it shouldn't be banned. when you score goals like that you feel proud of yourself. the research will continue but some feel the time to act is now, as football's fight with dementia goes on. cricket now and england have just edged the first day's play in the third test against south africa. england looked in trouble when captainjoe root was clean bowled for 27. but after that, an unbeaten stand from ben stokes and ollie pope saw

england reach 224 for four. the series is level at one apiece. tumbleweed — that's what the owner of this antique and second hand book shop in hampshire tweeted in desperation this week. he hadn't sold a single book all day — the first time ever in its 100 history, he thought. so he asked for help. and he certainly 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 fairytale. 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 this may be the first time ever." the message was spotted by bestselling author neil gaiman, who retweeted it to his 2.7 million followers.

the orders then came flooding in. someone from inverness rung up and said, "i want to spend £10. i don't care what the book is, just send it to me and i'm going to get my friends to do it." someone from california wants to donate $50. and it's just the love of books. you cannot beat a book. you touch and feel them, they become like good friends. in a shop where weird meets words, new customers have been arriving all day. a second hand book shop, a book shop like this is a treasure trove of amazing things. it's 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 1,000 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. a lovely story. time for a look at the weather. here's philip avery. i will soon put an end to that merriment! thanks to the low pressure, the cloud is thickening down through the central and western parts of the channel and that's why we will see some intensity about the rainfall getting into the south—east during the course of the evening and into the wee small hours. the met office have a weather warning about that, local radio and ourselves will keep you up—to—date with that. weather front eventually gets away from the far south—east, clearer skies behind for some. temperatures tumbling into single figures. plenty of showers, the low pressure still close to the north of scotland, windy there throughout the day and showers getting down through scotla nd showers getting down through scotland and northern ireland.

showers that were in wales and the south—west gradually migrating east through the day and generally speaking a fresh fields of the day, certainly away from the south—eastern quarter. that is nothing compared to what we achieve through the weekend because high pressure builds and we haven't seen that for a while. the week has been driven by low pressure and a lot of wind. the weekend starting on a frosty note with showers coming in ona frosty note with showers coming in on a noticeable north—westerly breeze, but elsewhere that is a glorious day. no more than double figures on the temperature front. despite all of the sunshine, and it is followed under the clear sky is by no surprise a chilly start and a frosty one is a sunday morning. but it isa frosty one is a sunday morning. but it is a great weekend for the outdoors provided you are not expecting he'd to go with the sunshine. not too much in the way of breeze and we are looking at plenty of sunshine and are high on sunday of sunshine and are high on sunday of seven or eight. sophie. thank you. that's all from the bbc news at six

so it's goodbye from me and on bbc one we nowjoin the bbc‘s news teams where you are.

hello. this is bbc news. the headlines... we are out of time, as world leaders need to make lyford let billy make that the decision on climate change andi that the decision on climate change and i possibly one from sir david attenborough. we have been putting things off year after year. —— a warning from. we have been raising targets and single year, if we do it within the next 20 years,... the moment of crisis has come. number showed the figures of knife crime are at the highest they've been in a decade. what went wrong for labour party the last election? one of the candidates in the party leadership sir keir starmer says they need to

look back a lot further
