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 whats 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. Heres 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. Lets 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 years 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. Thats 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, im really concerned. Peoples perspective is that the ocean, you know, its so big, its 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 its 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, theyve been surveying the worlds plankton continuously for almost a century. Over the last 50 or 60 years, weve been seeing some plankton species having to move further north, and thats having a direct impact on the wider ecosystem. So plankton are incredibly important, they provide over half the worlds oxygen, so thats 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, arent they . They are worried. About this, arent they . They are worried it about this, arent they . They are worried. It is about this, arent they . They are worried. It is a about this, arent they . They are worried. It is a global about this, arent they . They are worried. It is a global average. Worried. It is a global average taking across all of the worlds 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 worlds 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, whos 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 didnt post online. Police body cam footage of her and her mothers 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 didnt repay him money that he claimed hed 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 hed 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 dont 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, theyre trying to ram us off the road. Please, im begging you. I think im 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 victims family, who said this was the verdict their children deserved. The jailed russian Opposition LeaderAlexei 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 russias most famous prisoner. Wed been let inside the High Securityjail where Alexei Navalny is already incarcerated. But journalists werent 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 hed 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, hes 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 Putins handling of it. Now hes 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 todays 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 crouchs 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 crouchs 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 todays 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 wasnt 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 hadnt asked for help. Even when they were arrested, she and crouch continued to pretend they didnt know what happened. Despite his injuries, if either had takenjacob to a doctor in the hours before he died, he couldve 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 countrys 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. Weve been on site for a while supporting our team and our members here as well. Were 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. Thereve 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, theres been issues with not getting enough drinking water, theres been issues, just basics, really, like not having enough food. With a week still to go, the uk Scout Association has tonight decided its unsafe for its 4,000 members to stay here any longer. Theyre 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 theyve 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 provinces withdrawal leaving the event with no immediate future home. Behind the scenes with londons 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 countrys black sea naval fleet. Ukraine has claimed responsibility it tends to whe
