welcome to newsday. reporting live from singapore, i'm arunoday mukharji. the headlines. the us supreme court deals a major blow to efforts to tackle climate change, with a ruling limiting government powers to cut greenhouse gas emissions. president xijinping has arrived in hong kong, on his first trip out of mainland china since the start of the pandemic. as nato leaders wrap up their summit in madrid — president biden says the united states and its allies will stick with ukraine for as long as it takes. sri lanka's worst economic crisis deepens — the island is close to running out of fuel

and — temperatures in japan are the highest in nearly a 150 years, amid fears the electricity grid could be overwhelmed hello and welcome to the programme. the us supreme court has issued another landmark ruling, this time limiting the government's ability to regulate emissions from power plants. it marks a victory for the coal industry, but the united nations has described it as �*a setback in our fight against climate change�*. the us is the world's second biggest emitter of greenhouse gases, and the decision is a major blow to president biden�*s plan to reduce emissions. from washington, here's our north america editor, sarah smith. in california today, wildfires burning out of control are a vivid reminder

of the urgent need to take action on climate change. america is a large part of the problem — the second biggest emitter of greenhouse gases in the world after china — but also a victim. you can see from the water line above the vast lake how much it has shrunk in recent years, impacting the water supply for millions of people in the south—west. president biden came into office pledging to lead a global effort to reduce carbon emissions, promising in glasgow last year to lead by example. will we act and do what is necessary? will we seize the enormous opportunity before us? will we condemn future generations to suffer? future generations may not thank the us supreme court for a decision that restricts the federal government's ability to regulate energy producers. this ruling makes it harder forjoe biden to try to meet his climate change goals. the court has decided the environmental protection agency does not have the authority

to impose carbon limits unless there is new legislation coming from congress, and that's something joe biden knows he doesn't have enough votes to get past. coal lies at the heart of the problem. america still relies heavily on this most polluting fossil fuel to keep the lights on. a supreme case court was brought by 90 mostly republican states afraid they may be forced to move away from call to generate electricity. they have an outside share of america's carbon emissions and have done little so far to reduce them. a democrat—run state, its spending billions — more than most countries to protect the environment — but that effort will be undermined by the supreme court ruling. the idea that the us supreme court moved to take away one of the most significant, historically powerful tools to address the ravages of climate change is incomprehensible. in the states that won this

case, they are celebrating a ruling that gives them a right to make their own rules on carbon emissions, rather than be told what to do by washington. and they say it will prevent a rise in the price of electricity. andres restrepo is a senior attorney with the us based environmental organisation the sierra club who were involved in the case. he says despite the supreme court ruling, there are other legal means to fight climate change in the us. the rationale of the court, which is a harsh blow, which the cell is that the court read the cell is that the court read the governing provision for this regulation to limit the authority of epa not to control greenhouse gases period. i was not quite right. it still has

authority to control greenhouse gases —— that was not quite right. epa is able to impose regulations and can only consider technology and measures that can be implemented at each individual source as opposed to what the obama administration had done, which was that the stringency based upon the ability of plants to shift generation away from those fossil fuel sources and towards new renewable energy, which is the most effective tool that epa has for controlling the pollution. although the authority to control greenhouse gas emissions does remain, its ability to a set limits our six seriously curtailed by this. the us accounts for nearly 14% of greenhouse gas emissions. what are the legal resources

available?— available? well, the agency will still have _ available? well, the agency will still have authority - available? well, the agency will still have authority to i will still have authority to control existing fossil fuel power plants. but the agency, it's power plants. but the agency, its authority to control vehicle emissions from cars and trucks remains fully intact, and that's a sector with even more significant greenhouse gas emissions. at the same time, this case does nothing to affect state authority to control fossil fuel fired generation. as we've seen in a significant amount in the last five to ten years, there's really been dramatic move away from fossil fuels, even under the trump administration, which did its best to stop that. we've seen the retirement of 357 coal plants in the united states, and we will see more of that thanks in no small part to

efforts in the you environmental community. although this decision is certainly a blow, there are still tools the government has to control notjust power plants, but the transportation sector, oiland plants, but the transportation sector, oil and gas and governments to facilitate that away from fossil fuel generation. china's president xi has arrived in hong kong to take part in events to mark the 25th anniversary of the handover by the uk. this was the scene at the railway station as mr xi arrived. he was greeted by the outgoing chief executive carrie lam, as well as lines of schoolchildren waving flags. the chinese leader is expected to attend a ceremony to inaugurate hong kong's new top officialjohn lee. but earlier, british prime minister borisjohnson said china had failed to meet its commitment to respect a �*0ne country, two systems' arrangement agreed

under the deal that ended british colonial rule in 1997. on the 25th anniversary, we recently cannot avoid the fact that for some time now, beijing has been failing to comply with its obligations borisjohnson there on hong kong. well, mrjohnson was one of the nato leaders to pledge more financial aid and weapons for ukraine. the alliance also renewed calls for president putin to end the invasion. nato's secretary generaljens

stoltenberg insisted that ukraine must prevail as an independent state. here's our political editor, chris mason. salisbury plain, usually a place where british troops train. now those in ukrainian uniforms are here, too, being taught how to use the weapons and equipment being given to them by the uk. this as the prime minister, at the end of the nato summit in madrid, promised more money to help ukraine further. the best way for us to win the argument around the world about our values is for the ukrainians to win. that's why i'm pleased today that we've announced another £1 billion worth of military support. so, prime minister, what is the overall objective of the uk's help and strategy for ukraine? we want to give them the means to repel the russians, to expel the russians from the territory that they have occupied, because that is the right thing under international law.

this gathering of the world's biggest defence alliance has had a sense of urgency — even emergency. an invasion in europe, a hostile russia, an ongoing war without obvious end — huge human suffering, profound global economic consequences. president putin has been meeting his allies in turkmenistan. his decision to go to war in ukraine has spooked others close to russia's borders. for years, sweden and finland felt sufficiently safe to be neutral. no longer — russia's aggression means they're joining nato. translation: we don't - have a problem with sweden and finland, as we do with ukraine _ ukraine and its people's well—being is not the aim of nato or the west. it's just a means to defend their own interests. the prime minister has spent the last few days urging other countries to commit more to defence spending, while facing criticism at home that the british army

is shrinking. nice to meet you, how are you doing? he's also faced criticism from the scottish and welsh governments, who feel, while helping ukraine is noble, they've been pickpocketed by the government at westminster to help pay for it. but he's set a big, long—term goal, saying that, by the end of the decade, the money allocated to defence will rise to 2.5% of national income — much more than most other countries. borisjohnson�*s been out of the country for eight days, and a return to the domestic fray awaits. chris mason reporting. wall street has had its worst performance for the first half of the year since 1970. the s&p 500 closed down almost a full percentage point today on the last day ofjune — putting it 20% off its peak injanuary. investors are wary amid high

inflation and supply chain issues, which are fueling fears of recession — in the us and in the world's other major economies. the president of sri lanka is under continued pressure, amid the country's worst economic crisis since its independence. the island is close to running out of fuel which it can't afford to import. this week, it closed schools and stopped providing fuel to all but essential services. now, president gotabaya rajapaksa has written to vladimir putin to discuss buying cheap oilfrom russia. our south asia correspondent rajini vaidyanthan reports from the capital colombo. an endless struggle for this island nation. queues that go on and on and on. sri lanka's running out of fuel... ..and of hope. with only days of petrol left in the country, all they can do is wait. at the front of the line, taxi driver ajeevan. you're number one in the queue,

how long have you been waiting? two days, maybe. two days? yeah... translation: i've been sleeping in my taxi. - sometimes i leave to get food, then i come back here and sleep. that's how i've been living in the last few days. i can only survive if i have fuel. here, the pumps are dry. with no international shipments due for at least few weeks, what's left in the country is being rationed. these tiny pieces of paper have become one of the most sought—after things in sri lanka. they're fuel tokens, and everyone in this stretch of the line could be waiting days just to get one. and once you have one in your hand, you then have to wait for your petrol station to say that they have supplies of fuel. now, the owner of this particular token got it on tuesday, and his local station says they still don't have any fuel for him to pump. near the end of the queue, we find jayinda. he drove here from his

village, using up fuel, in the hope of finding more. only without gas, petrol, everything, we need everything, but it's difficult, not supplying continuously. that's why we are in deep trouble here now. and that's led to deep frustration and anger towards the government. the country's president's appealed to russia for help. a delegation is due in moscow at the weekend to discuss the purchase of cheap oil for this nation. do you usually ride bikes? back at the queue, jaganathan�*s just bought his first ever bike to get around. now, no petrol, no diesel, everything, j bicycle very expensive. the cost of cycles has tripled. inflation�*s at more than 50%. sri lanka's economic crisis keeps getting worse. how long must they wait for things to get better? rajini vaidyanathan, bbc news, colombo.

we heard on the ruling of us powers to tackle emissions. let's turn to japan now, where an unprecedented heatwave has got many worried about a possible shortage of electricity to keep air conditioners going. tokyo reported record breaking temperatures on thursday — making it the worstjune heatwave injapan since records began nearly 150 years ago. our tokyo correspondent, rupert wingfield—hayes, reports. in this town, it is another blazing hot day. at 11am, the temperature is already somewhere north of 40 celsius. for masaya, his wife and brother, working outside in these conditions isn'tjust hard, it's dangerous. masaya shows me the electric fans in his jacket, designed to keep him cool, but they hardly seem up to the task. "it went up to 47 degrees on the car's thermometer yesterday," he tells me. "is it dangerous?" i ask. "yes, it's dangerous.

"we've never had temperatures like this before injune. "usually, it's raining now." a week ago, most people had never heard of this little city, 100 km north of tokyo. now, it's suddenly famous. this is now officially the hottest place injapan. it's been above 40 degrees twice already this week, and according to my thermometer, it's well above that out there in the sunshine today. this has never happened before injune anywhere injapan. this should be the middle of the rainy season, and it's causing huge problems forjapan�*s electricity—generating system. it's just barely keeping up with demand, and if it fails, people are going to die. these heatwaves are notjust a natural fluctuation in weather. man—made climate change is making them more extreme and more dangerous. over the past 100 years, the average temperature for the japan has risen by about one degree, which is

more than a world record. for tokyo, it was like three degrees higher, so temperatures have been rising. so, definitely, climate change is part of the reason. the increasingly frequent heatwaves are particularly dangerous for old people, of which japan has many. so, here in the north of tokyo, they've opening a cooling—down centre, where i find this 86—year—old taking refuge from the heat and playing japanese chess. "i'm overwhelmed by the heat," he says. "coming here to cool down is really important. "i don't want to use the air—con at home, "but we've been told if we don't, we could die." four years ago, another heatwave killed scores of elderly people and put 20,000 in hospital. this one is expected to break on sunday, and for millions of people across japan, it won't come a moment too soon. rupert wingfield—hayes,

bbc news, in tokyo. let's take a look at some other stories in the headlines. at least six people have been shot dead and many injured during pro—democracy protests in the sudanese capital, khartoum. large crowds gathered in several cities, calling on the army to leave politics, following a military coup which toppled the government last october. bridges in khartoum have been blocked and the internet has been cut off to try and stop people marching. poland says it has completed a new steel fence along its border with belarus to curb the flow of undocumented migrants. the $350 million barrier is overfive metres high and will be equipped with surveillance cameras. it was built after a surge in the number of people fleeing poverty and conflict — mostly from the middle east. poland has accused belarus of actively encouraging people to make the journey. the ice cream maker ben and jerry's has said it doesn't agree with a deal made by its parent company, unilever, which allows its ice

cream to be sold in israeli settlements in the occupied west bank. ben and jerry's stopped selling its ice cream in israeli settlements last year, saying it was inconsistent with the company's values. in afghanistan, the taliban are holding a gathering in kabul of more than 3000 muslim clerics, scholars and tribal leaders from across the country. religious, social and economic issues are being discussed, but no women have been included in the meeting. from kabul, the bbc�*s south asia correspondent yogita limaye reports. for the first time since they seized power in august last year, the taliban are holding a national meet. for more than 300 districts of afghanistan, clerics and tribal elders have come to kabul. but no media allowed. and no photo or video of the gathering has been released so far. the roads to

the meeting tightly secured, but earlier in the day, a gun battle took place outside. a little known anti—talleyrand group claimed responsibility —— anti—tele— band. on wednesday, this video was released showing preparations for the meeting. in which the taliban hopes to get an endorsement from muslim scholars and tribal leaders in the country. but women and people from different ethnic groups have been excluded. and when asked about whether a decision on lifting the band on secondary schools were girl would be discussed, the answer was vague. translation: girls' exit patient is definitely an issue. people want it. it is a need for the future as well. but for the conditions to be suitable and all religious scholars to reach

kabul. tennis now — and it was a rainy day four at wimbledon — where rafael nadal is through to round three — and britain's katie boulter, who had a wildcard, was a surprise winner. our sports correspondent, chetan pathak, was watching the action. the great champions have a habit ofjust finding a way to win. that's exactly what rafael nadal showed here on thursday on centre court. he hasn't played on grass for three years when you consider these championships were postponed in 2020 and he missed wimbledon entirely last year. but he's finding his feet underneath the grass. again, he may have dropped a set against ricardas berankis, but his hopes of winning a third wimbledon title continue in this extraordinary year, where he's already won the french open and, before that, the australian open. his biggest fan is the world number one, iga swiatek. she survived a big scare and also progressed to the third round. thursday's stand—out result here — for the british fans, at least — involved home favourite boulter. at 25 years old, her career plagued by injuries. she's now ranked

outside the top 100. she knocked out last year's beaten finalist, karolina pliskova, the biggest win of boulter�*s life. she's never reached the third round of a grand slam until now. after the match, she dedicated her win to her grandma, who died only two days ago. and also worth keeping an eye out for two former champions looking very good — simona halep is through to the third round, as is the two—time winner petra kvitova. and in the men's draw, all eyes on a fascinating third round match between the fourth steed stefanos tsitsipas, who won earlier in straight sets. he's now going to play nick kyrgios, who always gives us unmissable moments here at wimbledon. he also went through in straight sets against filip krajinovic. and we will be tracking all the developments right here on the bbc. you can find all on our

website. that's all for the moment. thanks very much for watching and do stay with bbc world hello again. well, thursday was a day of sunshine and showers. but the day showers were a lot bigger, there were loads more thunderstorms around than we've seen over the past few days and whenever you see big cloud tearing upwards through the skies like these, well, you know someone is getting soaked. someone lived in south newington as those heavy downpours came through here. really hefty shower. the showers and thunderstorms that developed through the day have actually kept going for the first part of the night as well and they have tended to migrate towards the pennines, north east england and will generally begin to fade away over the next few hours by the same time, will probably see some rain to spinning its way across the north sea and grazing northeast scotland over the next few hours. here are your morning temperatures. now, for friday itself, we've got low pressure in charge.

it's a day of sunshine and showers broadly speaking. however, we will see another low bringing some more general rain into northern ireland as we go through the afternoon. here's the forecast for wimbledon — the computer reckons it's dry. well, you might be lucky, i suppose. but i'd go for a chance of a shower, to be honest. the shower�*s going to be quite widespread, they'll get going to the morning and come the afternoon, some of them will turn heavy and thundery. the greatest chance of seeing those heavier showers will be across eastern areas and down the eastern side of england. down to about norfolk, i suspect. temperatures similar to recent days, high teens across western areas, low 20s in the east. feeling warm in the sunshine with a bit more of a breeze around on friday compared with the last couple of days. the weekend sees further weather fronts diving eastwards across the uk and so on saturday, we start off with this weak weather front. a band of rain pushing eastwards across england and wales and what follows is sunshine and showers again. some of them heavy, particularly across northwestern areas this time. it's here where we've got the greatest chance of seeing some thunder. and those temperatures not

really changing a great deal. low 20s in the east, but generally for most of us, we're looking at temperatures into the high teens. now, pressure starts to gradually rise from now, pressure starts to gradually rise from the southwest as we go through sunday. so, probably dry for wales and most parts of western england and probably the midlands, too. a few showers elsewhere, notably across scotland and northern ireland and temperatures, well, they haven't changed very much, have they? pressure will rise more generally into next week. so, more of us will enjoy drier weather, a bit more sunshine and it will start to get a bit warmer, as well.

welcome to hardtalk. i'm sarah montague. when the uk handed hong kong back to china 25 years ago, the last words of the departing british governor to the people of the territory were, "now hong kong people are to run hong kong. "that is the promise, and that is the unshakeable destiny."

the man who said those words, chris patten, now lord patten,
