hit their highest average surface temperature on record, as they soak up warmth from climate change — and scientists are warning this will have serious consequences for the health of the planet. the average temperature this week was nearly 21 celsius, far above what's typical for this time of year. the global average is around half a degree celsius lower — which might not sound much, but experts say they are worried. the oceans are vital to help regulate our climate and drive weather patterns, and are home to a vast range of species. here's our climate editorjustin rowlatt. marine scientists send down an array of instruments to assess the impact of warming sea water off the coast of plymouth. have we got a reading for today yet, do you know? i heard them say something around 18—19, which is 4 degrees higher than it should be. one of the most dramatic heat waves ever recorded in uk seas hasjust subsided, part of a global trend of warming waters. the ocean temperature, or the ocean itself, is what regulates the temperature of the globe, so when we see the very thing that regulates the temperature of the globe increasing in temperature, that should be a cause for concern. some 90% of the additional heat trapped on earth by man—made climate change is absorbed by the seas and the oceans. let's take a look atjust how high average global sea surface temperatures have been this year. the grey area shows the range of temperatures over the last a0 or so years. now look at this. the red line shows this year's temperatures. look how it peaks at 20.96 degrees celsius — far above the average for this time of year. and now look at this, that peak temperature is the result of a series of heat waves in the seas and oceans around the world. the redder the colour, the more intense the heatwave. and just look at the heat building up in the north atlantic and also in the mediterranean. and you could also see heat building in the pacific ocean. that's the beginning of the regular el nino weather fluctuation. it is a disturbing trend, say scientists. water temperature is a key driver of ocean currents, and they in turn help determine the weather. if currents change, if the gulf stream slowed or stopped, for example, that would have a huge effect here in the uk. personally, i'm really concerned. people's perspective is that the ocean, you know, it's so big, it's so vast, that it can buffer anything that humanity can throw at it, and the reality is that that is not the case. you know, everything has its niche within the ocean, and it's incredibly easy to break that niche and influence it and upset it. take plankton. these tiny plants and animals are crucial to life on the planet. virtually every sea creature either eats plankton or eats something that eats it. and plankton are sensitive to heat. at the marine biological association in plymouth, they've been surveying the world's plankton continuously for almost a century. over the last 50 or 60 years, we've been seeing some plankton species having to move further north, and that's having a direct impact on the wider ecosystem. so plankton are incredibly important, they provide over half the world's oxygen, so that's every other breath that we are taking right now. and they are also providing food for so many species within the marine food web. the fish species in the seas of the uk are already changing, but there is hope. scientists are learning more about how the ocean ecosystems function every day. we have the renewable technologies that can tackle climate change by reducing our use of fossil fuels. we just need to make the change quickly. and justin is with me now. and scientists really are worried about this, aren't they? they are worried. about this, aren't they? they are worried- it _ about this, aren't they? they are worried. it is _ about this, aren't they? they are worried. it is a _ about this, aren't they? they are worried. it is a global— about this, aren't they? they are worried. it is a global average . worried. it is a global average taking across all of the world's oceans but from that graph it is more than half a degree celsius above where it should be. that is a very significant change. the other thing is this record temperature has been recorded at the wrong time of the year. 60% of the world's oceans are in the southern hemisphere and it is in the middle of the southern winter. in march you would expect global peaks that we are seeing at the end ofjuly and august. and the third thing i mentioned in my report is the el nino which means the pacific ocean is warming. that is just beginning. we have a record temperature and we know it is building on the pacific ocean and we can expect many more hot days and weeks and many more records to be broken, i suspect. weeks and many more records to be broken, isuspect. just weeks and many more records to be broken, i suspect.— broken, i suspect. just then, thank ou for broken, i suspect. just then, thank you for nova _ a tiktok influencer and her mother who were accused of killing two men during a high—speed car chase near leicester, have been found guilty of murder. mahek bukhari, who's 2a, and her mother ansreen bukhari were convicted of the murder of saqib hussain and mohammed hashim ijazuddin in february last year. 0ur midlands correspondent navtejjohal reports from leicester crown court. mahek bukhari wanted to be known as a social media influencer, spending much of her time on tiktok. but it was the events in her life offline that have now made her infamous. where were you? where was that? this is a video she didn't post online. police body cam footage of her and her mother's arrest on suspicion of murder in february last year. they arrived at this point due to a three—year relationship between her mother, 46—year—old ansreen bukhari, and 21—year—old saqib hussain. the court heard that when bukhari broke off the affair, saqib hussain threatened to send sexually explicit material of her to her husband and son if she didn't repay him money that he claimed he'd spent on her. in response, the jury were told the bukharis hatched a plot with the help of others to seize mr hussain�*s phone, containing the explicit material. he agreed to meet them in leicester under the belief that he'd be receiving payment. he was driven there by his close friend hashim ijazuddin. but the proposed meeting quickly became a deadly chase with the bukharis and their group in two cars following the two young men in their vehicle. in a police interview after her arrest, mahek bukhari lied, claiming she was an innocent driver just witnessing a chase. so i looked at mum, i go, mum, what is going on? what is wrong, are they. ..7 i don't know if they drunk, what are they. ..? what are they trying to do to this blue car in general? a short distance from here on the a46 is where the crash took place. just beforehand, saqib hussain was on a 999 call telling the operator that he was being followed by people wearing balaclavas. he says, "they're trying to ram us off the road. please, i'm begging you. i think i'm going to die. " mehek bukhari and her mother have been found guilty of their murder. raees jamal, who was driving the car that hit the victims. and rekhan karwan, who was driving the vehicle carrying the bukharis, have also been convicted of two counts of murder. three other defendants have been found guilty of two counts of manslaughter and one cleared of all charges. navtejjohal, bbc news. as the verdicts were read out here at leicester crown court at the end of a trial that has lasted more than three months, mahek bukhari burst into tears. there was little reaction from the other defendants. a short time ago we had a statement from the police in which they describe the actions of the killers as callous and cold—blooded and we also heard from the victim's family, who said this was the verdict their children deserved. the jailed russian opposition leader alexei navalny has today had his sentence in prison further extended. mr navalny who is already serving a nine—year sentence for fraud and contempt of court was found guilty of new offences of setting up an extremist network. the charges are widely viewed as politically motivated. 0ur russia editor steve rosenberg sent this report. this is the closest we were allowed to get to russia's most famous prisoner. we'd been let inside the high—securityjail where alexei navalny is already incarcerated. but journalists weren't allowed into the makeshift courtroom. we had to watch on a screen. for the kremlin critic, this is a trial behind bars. he was found guilty on extremism charges. punishment — more jail time. he was handed a 19 year prison sentence. we may have been allowed in here to watch the verdict on a tv screen, but keep in mind that in this court case, the actual proceedings were closed to the press and to the public and held in a high security prison. describing this trial as "behind closed doors" feels like an understatement. ahead of the verdict, in a message online, mr navalny wrote that a long prison sentence for him was designed to scare russians. he revealed he'd soon be on trial again for terrorism. they chant a charismatic protest leader and anti—corruption crusader, alexei navalny fell foul of the kremlin long ago. in 2020 in siberia, he was poisoned with a nerve agent and airlifted to germany. he claimed the kremlin tried to kill him. the russian authorities deny it. on his return to russia in 2021, he was arrested and jailed. ever since, he's faced trial after trial, punishment after punishment. it indicates that this regime is ready to be extremely cruel. it sends messages to the broader audience. we will not stop. the machine is working, and it means that they are ready to continue all possible trials against all possible dissidents. that includes this man. igor girkin is no pro—democracy liberal. the russian nationalist backs the war in ukraine but has criticised vladimir putin's handling of it. now he's under arrest, as the kremlin tries to crack down on any kind of criticism. back at the navalny trial, once the verdict was delivered, we were ushered off the penal colony premises. but after today's conviction, with possibly more charges against him to follow, alexei navalny looks set to remain locked away for years to come. steve rosenberg, bbc news, russia. a man has been sentenced to life in prison for murdering his io—month—old stepson. craig crouch was told he will serve a minimum term of 28 years. jacob crouch was found dead in his cot with dozens of injuries at his home in derbyshire in december 2020. his mother gemma barton was jailed for 10 years, for allowing his death and for child cruelty. you may find some of the details in this report from phil mackie distressing. a family member who spoke in court today said that since jacob crouch's murder, no holidays, birthdays or christmases would ever be the same again. another said the pain of his loss would be with them for a lifetime. his stepfather, craig crouch, inflicted the injuries that killed him. his mother, gemma barton, allowed him to die at crouch's hands. he was a happy, smiling, bubbly baby, who never complained about the horrific treatment he was receiving. he had to put up with it, and he did, often with a smile and laughter in defiance of his tormentor. even those of us who never knew jacob personally will miss him. during today's hearing, we heard how crouch had exerted coercive control over gemma barton, who was described as being vulnerable when they first met. there always has to be a leader in everything that we do. this is part of a bizarre voice message he left which was played in court, and shows how crouch set out to take control of the relationship. this also has to stand at home. jacob died at the end of 2020 after a series of lockdowns and a period of social distancing. and even though he wasn't known to social services, craig crouch was able to use that and his coercive control of gemma barton to isolate the family to avoid scrutiny and to hide what was going on behind closed doors. while no sentence can bring jacob back, i hope that today brings the family some closure on what has been a horrific two and half years. i would like to thank them for the respectful and dignified manner in which they conducted themselves throughout the trial. today, one family member asked barton directly in court why she hadn't asked for help. even when they were arrested, she and crouch continued to pretend they didn't know what happened. despite his injuries, if either had takenjacob to a doctor in the hours before he died, he could've been saved. phil mackie, bbc news, derby. more than 4,000 scouts from the uk who are attending the world scout jamboree camp in south korea have been moved to hotels, after people had to be treated for heat related illnesses. hundreds of children have fallen ill at the outdoor event, after temperatures hit 35 celsius in one of the country's hottest summers. 0ur correspondentjean mackenzie reports from seoul. this is the glastonbury festival of the scouting calendar. but from the minute 40,000 scouts arrived here to camp in the scorching heatwave, it morphed into a real—life survival mission. we are fully aware of the temperature conditions. we've been on site for a while supporting our team and our members here as well. we're putting in lots of support for our young people to make sure they have an incredible experience. these teenagers, trying everything to stay cool. but the lack of shade and air conditioning has made it impossible. hundreds have already needed medical treatment. but the heat is not the only culprit. there've been complaints about the facilities, the food and access to water. some have saved for years for this once—in—a—lifetime adventure, leaving parents back in the uk frustrated and concerned. i would suggest that the south koreans were not prepared for this event. i mean, obviously they knew there were 47,000 young people coming from all over the world, and there have been issues with sanitation, there's been issues with not getting enough drinking water, there's been issues, just basics, really, like not having enough food. with a week still to go, the uk scout association has tonight decided it's unsafe for its 4,000 members to stay here any longer. they're being moved to hotels at the capital, seoul — a huge disappointment for many. "be prepared" is the scout motto. south korea, it appears, was not. jean mckenzie, bbc news, seoul. our top story this evening. scientists say our oceans have hit their warmest ever recorded temperature as they soak up heat from climate change. coming up... the afghan families facing homelessness after being told by the government to leave the hotels they've been staying in. coming up on bbc news... first victoria, now alberta, the commonwealth games is too expensive for its two next prospective hosts, with the canadian province's withdrawal leaving the event with no immediate future home. behind the scenes with london's air ambulance. ukraine says it has successfully attacked a russian navy ship using an unmanned sea drone, which was carrying nearly half a tonne of explosives. the ship was docked in the port of novorossiysk, which is a major hub for russian exports. a video released by the ukrainian security services appears to show such a weapon hitting the side of a russian naval vessel. from kyiv, our ukraine correspondent james waterhouse reports. in waters dominated by russia, ukraine relies on stealth. under the cover of night, this sea drone moves towards towards the 0lenegorsky gornyak, a russian warship typically used for carrying supplies, meets a hunter designed to detonate on impact. under the light of the next day, the vessel appears to be badly damaged and is towed to shore while leaning to the side. novorossiysk is a major russian export hub for oil and grain. it also supplies the country's black sea naval fleet. ukraine has claimed responsibility — it tends to when it comes to sea drone assaults on the black sea, as with the recent damage to the kerch bridge, connecting occupied crimea to mainland russia. it's also been a fortnight where ukrainian ports have been pummeled by russian missiles. ukraine hopes attacks like these will make russia think twice about flexing its muscles on the black sea. it's clearly trying to hit back where it can in the face of relentless missile attacks. kyiv�*s allies have long been worried about this war spilling over. so what do they make of these attacks further afield? according to one presidential adviser, they seem to be more relaxed. translation: it is clear - that it is impossible to win the war if you are not actively attacking. you can'tjust watch it happen. we are at war. our partners have already realised it is notjust a small conflict. war is war. it is necessary to destroy the capabilities of the other side. what kyiv doesn't admit to are the increasing number of drone strikes closer to moscow. it claims to draw a line on what it targets, sayong occupied territories like crimea and threats in the black sea are fair game. regardless, this war�*s footprint seems to be getting bigger. james waterhouse, bbc news, kyiv. the controversial influencer andrew tate and his brother have been freed from house arrest in romania, pending a trial on rape and human trafficking charges. the brothers have been under house arrest since march and were charged injune — they deny the charges. they are now free to move around the capital bucharest and the surrounding district, but have to abide by various legal rules for 60 days. the partner of a pregnant woman who was killed by a man filming himself speeding at more than 120 mph has called the killer's prison sentence insulting. adil iqbal was jailed for 12 years after admitting causing the death of frankiejules—hough, a former hollyoaks actress. she'd pulled onto the hard shoulder of a motorway in greater manchester with a puncture, when she was hit by iqbal�*s car. her partner calvin buckley has been speaking to bbc breakfast and said iqbal�*s sentence didn't reflect the harm he had caused, and should be increased. matt cole reports. thoughtless, reckless, and ultimately life—taking. driving one—handed so he could film himself at i23mph, these were the moments before adil iqbal lost control of his car, crashing into frankiejules—hough on the hard shoulder. 30 minutes before the incident, said goodbye, said i love her, which i'm really happy that i managed to do that, because we did get a proper goodbye, and then i got a phone call saying that she'd been involved in a collision. frankiejules—hough, a former hollyoaks actress who was 17 weeks pregnant, died two days later. she never regained consciousness. her eldest son and nephew, who'd been with her in the car, were left with life—changing brain injuries. last month, adil iqbal was sentenced to 12 years in prison. not enough, say herfamily, who claim new sentencing guidelines brought in injune, which enabled life sentences, should have been applied. if people aren't getting tough sentences for this, they're going to keep doing it, and it's just disappointing and also insulting to the family that, to us, thejudge has been really lenient. the ministry ofjustice says law officers are currently considering a request for adil iqbal�*s sentence to be appealed as unduly lenient, adding in an statement that, "new laws have increased the maximum penalty to life imprisonment for causing death by driving to ensure punishments fit the severity of the crime. a week before the fatal crash, frankie and her partner, calvin, revealed their unborn child was a girl. now, without them, he's promising to campaign against dangerous driving, hoping to spare others loss like his. matt cole, bbc news. some afghan families given refuge by the uk are facing homelessness after being told by the government to leave the hotels where they've been staying since fleeing the taliban. the organisation which represents councils in england and wales says one in five afghans being evicted from a hotel have nowhere else to live. 0ur political correspondent ione wells is with me and has been looking at the details: these were the scenes in afghanistan two years ago — thousands of afghans trying to flee after the taliban seized control of the country in august 2021. the uk set up two legal routes for refugees to come here — for afghans who worked for or with the uk government, and other vulnerable citizens. in april, the home office said 24,600 people had been brought to the uk through these schemes. it said while over 10,500 afghans had been supported into settled homes, about8,000 remained in uk hotels ? half of whom are children. in march, the veterans minister johnny mercer said any afghans still in hotels would be written to and given at least three months' notice to move. but some have not yet found a place to live. the local government association says one in five afghans leaving hotels are telling local authorities they are homeless. amir hussain ibrahimi is 24 and has been living in a hotel in southend for two years, but has struggled to find a home. he has four days before he needs to move out of the hotel, and is worried for the future. i tried to find some place and i spoke with lots of landlords inside london, around london. but none of them would accept me to live with them or hire a room in their houses. i don't know what is the reason. the government says home office teams are working with councils to help afghans find accommodation. i think we have to understand what we mean by the term homelessness to start with. none of these people are going to end up sleeping rough. we've done a huge amount of work to help get these afghan families out of hotels and into long—term sustainable accommodation forthem in the uk, as was always the promise, as is what's best for them and what's best for british taxpayers. the home office says it's provided £285 million of funding to speed up the resettlement of afghan nationals into long—term homes and states that "hotels are not, and were never designed to be, long—term accommodation for afghans resettled in the uk". it is set to stop paying for the remaining hotels in the coming days and weeks, meaning the problem could continue to grow. ione wells. the knock—out stages of the women 5 world cup begin tomorrow ? and there 5 already been plenty of drama and upsets, including for two—time champions germany, who failed to qualify for the last 16 for the first time in their history. it means england's lionesses are now among the favourites to win the tournament ? but first they must beat nigeria on monday. katie gornall reports from sydney. in the tranquil surroundings of gosford on the central coast, england are plotting their next move. expectations are rising round sarina wiegman�*s side after they soared into the knockout stages with a perfect record, and a 6—1 win over china. there's been a few shocks and surprises at this world cup, but so far, england haven't put a foot wrong. how the tournament goes, it's such a high level. and that's why it's important we just stay focused on what we are doing. we're not a team that takes anything for granted, and i think that's, that is what everybody should be looking at, the big names that have gone home, and reallyjust embrace every single minute. there have, of course, been challenges. keira walsh's knee injury against denmark sidelined one of england's best players. the barcelona midfielder is back training in the gym, with no time frame given for her return. without her, england have had to adapt. they played a new formation against china, which seemed to bring the best out of the squad. laurenjames, what a goal! and it got everyone talking. we don't necessarily know what sarina wiegman is going to do next, and that means the opposition don't either. is this a team that can win the world cup, though? yes. in a word, i think so. i thought it was tough for them with the draw the way it was, i really did, and i think there was a little bit of pressure on them going into that china game, and we saw it with the euros last summer, they got better and better in that tournament, and they played their best football in the knockout rounds, and i think we're seeing that again. i think england have to see this as they might never have a better chance to win a world cup, and yes, they are missing players, but they are really stepping up at the right time. with germany gone, the draw has opened up for england. the opportunity is there — now can they take it? katie gornall, bbc news, sydney. time for a look at the weather. here's louise lear. it is trying our patients at the moment, isn't it? this is the weekend. it says it all. another wet and windy story, i'm afraid, as we go into the weekend. but i have found a silver lining in all that cloud. it took some looking, but next weekend we have got high pressure building and we can offer you something a bit more settled and more summer—like. but let's talk about the cloud, the wind and the rain, i'm afraid, because this area of low pressure has been named storm anthony and is moving its way in across northern ireland as we speak. that is going to bring some heavy rain overnight. across northern ireland, the bright yellows and greens are denoting the intensity of that rainfall as it sweeps eastward through the isle of man. so we are going to see 20 to 40 millimetres quite widely. they have just had that what is july on quite widely. they have just had that what isjuly on record, which could lead to localised flooding. as the low drives eastwards, the winds will pick up, 50 to 60 miles an hour gusts of winds. the awful conditions for trying to sleep under canvas or even getting your caravan or camper van to its location. through the day, that low drift east, spiralling around, plenty of frequent showers. the best of the drier weather is in scotland, but look at these temperatures. yes, it is august and we are only seeing temperatures between 14 and 18 degrees. that is very disappointing. on sunday, it will be a quieter story. it's going to start off dry, even with some sunshine as the storm is as a way, but a rash of showers will develop from the north and west. some of these may be with the odd rumble of thunder mixed in. top temperatures a degree or so warmerfor thunder mixed in. top temperatures a degree or so warmer for sunday, because we will have a little more sunshine. hopefully, we should see them peaking at 22 degrees. monday and tuesday, still showers or longer spells of rain. but let's get to the glimmer of good news because wednesday into thursday, high pressure is set to build. we haven't seen this for quite some time, which means to the end of next week, we are likely to see a return to some summer sunshine and some summer pleasant warmth for most of us. we will hold you to that, louise! thanks. and that's bbc news at six. the news continues here on bbc one, as now it's time to join our colleagues across the nations and regions for the news where you are. goodnight. hello and welcome to sportsday — i'm hugh ferris. the headlines this evening. last season they were two divisions apart, but now they'll share a pitch on the new football season's opening night we also look ahead to how the scottish premiership might play out with an old new manager at the helm of the champions
