♪ anchor: i am in washington and this is bbc world news america. the world's oceans hottest ever recorded, having major implications for the planet. two u.s. sailors arrested for allegedly sharing secrets with one of the country's largest naval competitors. countries have provided ukraine billions of dollars in weaponry but russia is making problems for ukrainian troops. ♪ anchor: welcome to bbc world news america. we begin with a dire warning about climate change. scientists say the average surface temperature of the world's oceans has had a record high just under 21° celsius or

nearly 70 darren heitner in august -- or nearly 70 degrees fahrenheit in august. our climate editor reports. correspondent: they have been taking measurements of temperatures here in plymouth for more than a century and for the last 50 or so years, they have showed a slow but steady increase, up a third of the degree in a decade. >> [indiscernible] something around 18 or 19. correspondent: it has been a similar pattern globally, rising sea temperatures and increasing marine heat waves, and it has just reached the new peak, 20.96 degrees celsius, the highest global average sea temperature recorded. the worlds warming waters are a dangerous trend say experts. >> peoples perspective is the ocean is so big and so fast that it can buffered anything

humanity can throw at it and the reality that is not the case. everything has its place within the ocean and it is incredibly easy to break that and influence it and upset it. correspondent: take plankton, these tiny animals are crucial to life on the planet, the basis of the entire marine food chain and produce half the oxygen in our atmosphere, so every other breath you take, and they are sensitive to heat. many species have been migrating north as the world's oceans warm. >> personally i am really concerned that the heat waves we are experiencing on land and the marine heat waves we are seeing are happening in unusual locations where we have not expected them. correspondent: there is hope. scientist are learning more about how the oceans ecosystems function every day with renewable technologies that tackle climate change by reducing our use of also feels.

we just need -- use of fossil fuels. just need to make the change quickly. anchor: for more we can bring in carl nelson standing by in washington dc. carl, why are the world's ocean so important to the global climate? carl: they are incredibly important. united nations calls oceans are greatest ally in the fight against climate change. you heard justin touching on that but what oceans do is they soak up the extra co2 we produce by burning fossil fuels. it is a carbon sink, one of the most effective ways that art has absorbing emissions and the excess heat that humans produce, absorbed by the oceans. once those oceans start to warm up, warmer water is not as effective as soaking up that heat so we get one of those feedback loops warmer oceans

means warmer temperatures on land. we saw those extreme temperatures playing over the last few weeks and months. another thing to watch for is warmer waters lead to more frequent and more intense hurricanes. the atlantic hurricane season is on its way and scientist are bracing for that and trying to look into the reasons why. [birds singing] these are extreme temperatures very out of the norm, especially in the atlantic notion -- ocean p one theory is the sahara desert, normally dust from africa will be blown over the continents over the atlantic ocean and the atlantic ocean and that does can basically serve small reflectors bouncing light and heat away from the ocean and back into the atmosphere. we have not seen those coming across the atlantic ocean recently. that could be one reason why we are sink these record-breaking temperatures. [birds singing] anchor: carl, interesting information. thank you.

now, two new developers in the story of the american soldier in north korea. the u.s. had the claim to classify army private travis king as a prisoner of war despite the fact that he is in north korean custody after crossing into the country last month. this decision could mean mr. king is not covered by the protections given to prisoners of war under the geneva convention. this incident has become a question of the mid to late with its commitment to leave no soldier behind enemy lines. king willingly crossed into north korea during a tour in the u.s. is negotiating his return. two u.s. navy sailors have been arrested facing charges of providing sensitive military information to china. the 22-year-old is accused of conspiring to send national defense information to a chinese agent, and the 26-year-old petty officer was arrested on charges of accepting money for sensitive photos and videos. prosecutors say they were

allegedly approached separately by chinese agents who paid them each thousands of dollars for classified information. if convicted, they could face decades in prison. china has denied any knowledge of the alleged activity. the u.s. attorney for the southern district of california spoke in detail about the charges. >> our indictment alleges over the course of more than a year and on multiple occasions, he sent national defense information to china including documents, photos, videos and technical manuals. in exchange, his intelligence officers paid him thousands of dollars, the officer even congratulated him when he became a u.s. citizen in 2022. throughout this relationship, he provided his chinese handler with information regarding defense and weapons capabilities of u.s. navy ships, vulnerabilities potentially of the ships, and information related to ship movement.

anchor: in russia, president vladimir putin's fiercest domestic critic aleksei navalny received 19 years to a jail term on friday. he is already serving sentences totaling 11.5 years on fraud and other charges he claims are bogus. steve rosenberg sent in this report. correspondent: this is the closest we were allowed to get to russia's most famous prisoner . we have been let in the high-security jail where aleksei navalny is already incarcerated. but journalists were not 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 and handed a 19-year prison sentence. we may have been allowed in here to watch verdicts on the tv screen, but keep in mind with this court case, the actual proceedings were closed to the press and public, and held in a

high security prison. describing this trial as behind closed doors feels like an understatement. ahead of the verdict, and a message online, aleksei navalny wrote that a long prison sentence for him was designed to scare russians. he revealed he would soon be on trial again for terrorism. a charismatic protest leader and anticorruption crusader, aleksei navalny filed fell -- fell foul of the criminal years ago. he was poisoned with the nerve agent and airlifted to germany and claims the kremlin tried to kill him. the russian authorities denied it. on his return to russia in 2021, he was arrested and jailed. ever since, he has faced trial after trial, punishment after punishment. >> this regime is ready to be

extremely cruel. it sends messages to a broader audience, we will not stop. the mission is working. it means that they are ready to continue trials against all possible dissidents. correspondent: that includes this man, he is no pro-democracy liberal. the russian nationalist backs the war in ukraine, but has criticized vladimir putin's handling of it. now he is under arrest, as the criminal and tries to crack down on any kind of criticism. back at the aleksei navalny trial, once the verdict was delivered, we were ushered off the penal colony premises, but after today's conviction with possibly more charges to follow, aleksei navalny looks set to remain locked away for years to

come. steve rosenberg, bbc news, russia. anchor: in reaction to the sentence extension of an outside navalny, the u.s. state department said "for years the criminal has attempted to silence aleksei navalny and prevent his calls for transparency unaccountably from reaching the russian people. by conducting this latest trial in secret, russian authorities demonstrate again the basis of their case and the lack of due process afforded to those who dare to criticize the regime." a video has emerged showing a siege run driving into the side of a russian naval vessel in the black sea. the bbc has not verified this video, but the nighttime footage appears to show a drone driving into the side of a large ship and cutting out on impact. the video was released by ukrainian security services claim this ship suffered a serious breach, but russia's defense ministry says it repelled an attack and did not admit to any damage. james waterhouse filed this

report. correspondent: unlike these drone attacks we have seen deep inside russia around moscow for example, kyiv seems to be more willing to admit being behind the strikes using c drones on the black sea -- sea drones on the black sea. security services said they damage a major landing ship and a port on the russian coast. it is a major terminal where 1.8 one million tons of oil make their way out from there every day and it is also an important naval base for moscow. the security service sources have shared with those footage of the apparent moment of impact with an onboard camera. there is unverified footage of the vessel subsequently listing to one side, suggesting it has indeed been damaged, but in a fortnight where ukrainian ports have been pummeled by russian drones, it seems ukraine has been keen to respond.

it is interesting, because president zelenskyy has previously warned of the were coming to russia, and has been keen to apply pressure wherever possible, but in the same breath he said peace talks could happen as soon as autumn, but you need to look only at the invasion to see that in the above side is setting the conditions for peace talks to take place. anchor: in the early days of the full-scale invasion of ukraine borussia many observers were surprised how poor the army's electronic warfare units performed. 18 months later, their causing significant problems, affecting the most sophisticated weapons troops have received from nato countries. the bbc has more details. correspondent: the battles are invisible but the danger they face is real. this is a ukrainian electronic intelligence unit. their job is not to find the guns, but to monitor

transmissions, signals used by drones, air defense systems, multiple rocket launchers, and other weapons. we cannot show their faces for security reasons. the team leader says russian forces constantly hunt down units. their mission is part of a hidden confrontation called electronic warfare. how does it work? almost every modern weapon uses radio waves, microwaves, infrared or other signals to send and receive data, and electronic warfare uses this for nobility to disrupt communications, gather intelligence and identify targets. for the first time since world war ii, we are witnessing a conflict where both sides are heavily relying on electronic warfare systems as part of their military strategy. drones have become a key feature in this war, but this is what happens when they are jammed by

a laconic warfare systems. it is not just runs it can be affected. more sophisticated arms ukraine has received from nato countries use a gps link for navigation. so when russia jams the signal, even high precision weapons including high mars rocket artillery can mr. target. that is why russia and ukraine keep their electronic warfare or ew capabilities in secret. >> this wart represents us new and very effective -- war represents is new and very effective abilities of drones, radars, communications, and all of the system could be affected with ew means. if we destroy russian jammers, we improve capabilities of our troops in detection and the ability to have a precise strikes. correspondent: here, ukrainian special forces have spotted a

russian system the jams gps signals. ukrainian artillery put it out of action. but russia is on the hunt for ukrainian electronic warfare units too. the group comes under fire, meaning russian troops have discovered their antenna and are looking for their base. he tells everyone use single rounds in order to last until the morning. he decides to change their location because the position is compromise. the key in electronic warfare is being invisible to your enemy. bbc news, kyiv. anchor: let's get a quick look at other headlines. republican presidential nominee and former new jersey governor chris christie met with volodymyr zelenskyy in a surprise visit to kyiv on friday. he expressed his support for

ukraine and praised its president for having the resolve to survive war. the visit comes as the former trump ally turned rival makes a run for the 2024 election for the republican party nomination. new numbers showed job growth in the u.s. was weaker than expected. official figures show 187,000 new jobs while the unemployment rate dipped to 3.5%, a near record low, suggesting the labor market is cooling to analysts saying it is the latest on the u.s. will be able to bring down inflation without triggering a recession. former president donald trump is facing mounting legal woes. on thursday, he was arraigned for a third time over charges related to his alleged attempt to overturn the 2020 election. so let's take a look at what is coming next for the former president. the is still hitting the campaign trail. he spoke to a packed house of more than 2000 people in alabama today. he will not be attending his

superseding arraignment in the classified documents case after waving his right to be present. he is still waiting to hear back from the fulton county district attorney in georgia where he could be handed another indictment, including voter and election fraud charges. on august 28, the former president is due back in court in washington dc for a case. trump claims the charges are election interference by the justice department because he is currently the front runner for the republican presidential nomination. staying in the u.s., the two expelled members of the tennessee three have reclaimed their seats in the tennessee state house after they were expelled for their involvement in the gun-control protest on the house floor. justin j pearson, justin jones, gloria johnson took place in the demonstration just days after a fatal shooting in nashville. republican bob makers declared their actions violated house rules and moved to expel their three colleagues. johnson narrowly avoided

expulsion but the other two were ejected. the move briefly left voters in primarily black districts without representation in the tennessee house and drew national attention. joining us now is justin j pearson, one of the tennessee three reelected and thursday special election. great to have you back. i want to ask you and your colleague were heavily favored to win her districts but how does it feel to win your seatback? >> i am humbled and honored that district 86 representation has been restored. our district lost its voice temporarily i'll be at -- temporarily due to the actions of the super majority republican party tennessee. it was not just the expulsion of one or two members, it was people who went to the posters month before to get their voices heard to make sure that democracy was able to prevail, but the reality is we are dealing with a mobocracy in

tennessee where there is abuse of authority taking people's rights and taking people's voice away. anchor: so what message do you think your victory sends? >> it sends a loud and clear message that you cannot expel a movement. you cannot expel hope. and you cannot expelled the desire and will of people who want to see real action on the issues that matter such as gun reform and gun safety legislation, environmental protections,, the of elation that people who are in and have been made poor by the policies of economic exploitation. i think the message sent by the thousands of people who went to the polls in our district at the other district is we will not be silenced and we will not quit in advancing the issues that matter. anchor: there was national and international attention on your story after your colleagues and you were expelled in march and this was a name for reforming gumballs in your state after the shooting at covenant school in nashville.

what has changed since then? correspondent: i believe what has changed for the republican party and people across the country are two things. one, the republican party and others see there are millions of people ready to stand up and ready to fight back against the national rifle association, the tennessee bar association, the american firearms association that is profiting off the violence and the harm happening in our communities. the other thing that has been recognized across our state, country and world is we are losing our democracy, and when democracies are in peril, the communities that suffer the most are black communities, indigenous communities, community's of color and those made socially economically depressed, so everybody has to pay attention to what is happening because the erosion of democracy has serious implications for the united states of america but for other countries across the world. anchor: so there is a special legislative session called later this month by the republican governor in your state but have

republicans shown any flexibility for compromise on the issue of gun reform? >> the reason the governor called the session was the activation of tens of thousands of people who marched, protested, sent emails and wrote letters and had phone calls, so we are seeing the power of people, people power pushing this conversation forward, and i believe that some republicans who continue to see mass mobilization are realizing they cannot keep with the status quo and that children need to be safe in their schools, walking home, and their communities, because of a lot of places in memphis, we deal with gun violence every day and it is a tragedy to go to the funerals of 18-year-olds in young people, in some republicans are realizing their ability to remain in power and have political power will rest on whether they serve the entire community, including addressing gun violence. anchor: i want to ask you about how people feel in your state about gun reform laws. a poll from vanderbilt

university show 80% support red flag policies that separate people from their guns as they pose a threat to themselves. it is an issue that has not gained much support among republicans and they do dominate the legislature, so do you believe your colleagues in the legislature will meet you halfway on this issue? >> yeah. we need them to meet us 100% of the way on this issue. the super majority of the state want to see action with extreme risk protection orders, action as it relates to background checks, do everything in our power to make sure children and our communities are safe. gun violence is the number one killer of children in tennessee, not illness, car accidents, but gun violence. we have the power to do more as legislators than offer thoughts and prayers, so we would demand that the republican party do their jobs of making sure our communities are safer. anchor: what do you think

democrats nationally can learn from what you have done in tennessee? >> that people power movements work and we have to be proximate to the community suffering and the people experiencing harm and lift up their voices and praise up their voices to create change and there is no part of our country that can be left behind, where the the read estates on the reddest communities and, we have to be a party that elevates is voices. anchor: you and your colleagues saw a big boost in fundraising after the international coverage, as i mentioned. the plan to run for congress or senate? >> i plan to serve district 86 as a state representative as long as they will reelect me. anchor: justin j pearson, thank you for joining us. great to have you back on the show. >> thank you for having me back. let's keep going. anchor: all right. you can find more on all the days news at our website, plus see what we are working on
