debut since facebook. are you in the a warm welcome to the programme — briefing you on all you need to know in global news, business and sport. cientists at the university of cambridge have unveiled plans for a new research centre to re—examine old ideas to tackle climate change. today we want to know — what ideas do you have to repair the ea rth‘s climate? join in the conversation on twitter, just use the hashtag #bbcthebriefing. as we go on air, new us tariffs on chinese goods are due to come into effect.

levies on $200 billion worth of chinese goods will rise from 10% to 25%. it comes as talks in washington between trade negotiators fail to produce a breakthrough. more discussions are scheduled later on friday. the international monetary fund says the row poses a threat to the global economy. following all the latest developments from shanghai is our correspondent robin brant. pis p is the deadline has passed in $200 billion worth of good, vacuum cleaners, wi—fi router is, they are going to see the tariff, the tax placed on them by the us government more than doubling from 10% to 25%. no change on that. negotiations in washington dc, the meeting and a

working dinner, were not able to produce a temporary deal which would see this escalation frozen. the trade war has escalated. the thing now is, markets are in china, shanghai and elsewhere are a little positive in early trading because they're just happy the trade talks are going to continue into tomorrow. more talks tomorrow but the most significant event what about donald trump said because china broke the deal, as happened three minutes ago, that new wave of tariffs has been implemented. it was this in fact in? —— who is this effect in? implemented. it was this in fact in? -- who is this effect in? prices will go up. i mean, it's a wide range of goods. almost 6000 on the

list. but also originating from china. it ranges from vacuum cleaners, printed circuit boards, wi—fi router is. the us has been wide ranging. china sends a lot more to the us than the us sends to china. initially, people importing those goods would have to be the ones we pay the increased tariffs. more than doubling, and there is assumption that the many, that cost will be passed on to consumers. the next significant thing is to see what china does in riyadh —— retaliation. it says it's prepared for further action retaliation. it says it's prepared forfurther action on the retaliation. it says it's prepared for further action on the question is, will that be proportionate, a mirror of what the us has done, or will china go further? it has a far smaller pool of goods that come here from the united states that it can

target but in the past, it's targeted set is that a politically important for the present expect resident, particularly agriculture like soybeans. in south africa, with nearly two thirds of election results declared, the african national congress is on course to retain power. but the anc is heading for the worst performance in its 25 years in government. and that's likely to make it harder for president cyril ramaphosa to tackle corruption and fight poverty. this report from ramzan karmali. for most south africans, they all expected the african national congress to win the election but the real question was by how much? it seems the ruling party hasn't been able to prevent a slide in its support but party officials were putting on a brave face. so we have a very solid

idea of the response that we were going to get from the electorate and so no disappointment, no surprises, we are where we thought we would be at this point in time. and despite looking like it has gained less than half the anc‘s vote, the main opposition party leader was still feeling optimistic. as his party appears to have gained a larger section of the vote than the previous election in 2014. i've just looked at the initial projections, we are happy that we will retain the western cape, we are very clear about the fact that gauteng is still on a knife edge which is part of the work that we've done and i'm most grateful the fact for the fact that we've built an organisation that works for all south africans. one key issue in this election was the economy. unemployment currently stands at 27% which has led to a rise in the popularity of a new party, the economic freedom fighters. it was founded by an expelled member of the anc, julius malema. he's been calling for

a redistribution of wealth and the expropriation of white land. this looks unlikely, but his party is still on course for around a 10th of the vote. clearly, repairing an ailing economy will be high on the list for mr ramaphosa, but when he took overfrom his predecessor, jacob zuma, around two years ago, he vowed to crack down on corruption, something many voters will feel not enough has been done just yet. ramzan karmali, bbc news. i'll be speaking to a young member of the main opposition the democratic alliance in just a few minutes. let's brief you on some of the other stories making the news. the former us army intelligence analyst chelsea manning has been released from prison after serving a two month sentence. she'd been jailed for refusing to give evidence before a grand jury investigating wikilea ks. but she'll have to appear again before a grand jury next week, and refusla to testify could lead to another spell in jail.

three venezuelan mps have taken refuge in the italian and argentinian embassies as the government of nicolas maduro increases pressure on the opposition. they're among ten mps stripped of congressional immunity earlier this week on the recommendation of the pro—government supreme court. it said they should be investigated for conspiracy, rebellion and treason for allegedly taking part in the botched uprising at the end of april. a german woman who scammed her way into new york high society has been sentenced to up to 12 years injail. the opulent lifestyle of russian—born anna sorokin was paid for by a string of unpaid loans and bills involving hotels, restaurants and banks. she pretended to be a wealthy heiress. it's the most anticipated flotation on the new york stock exchange since facebook.

later on friday, shares in the ride — hailing company uber will go on sale. but it looks like the firm is playing it safe when it comes to the starting price. it is looking more like $82 billion, it was thought to be $120 billion. we will see at trading. low end of the market, are they playing safe? 0r the market, are they playing safe? or is that an overestimation? they are playing it safe. we've seen what's happened with uber‘s rival, lyft. lyft‘s ipo didn‘t what's happened with uber‘s rival, lyft. lyft‘s ipo didn't go so well.

it's lost about a third of its value. they are playing a bit cautious. just for our viewers around the world, ipo means initial public offering. to offer its share for the market for investors to buy. they prioritised institutional investors. people they hope will be holding onto the stock for a long time. is this a long—term bet. holding onto the stock for a long time. is this a long—term betm has to be because uber is very unprofitable. part of the reason it's going public is to raise a huge tranche of funding that will fill up its balance sheets and cash pile, give itan its balance sheets and cash pile, give it an immediate injection of funding. it's not clear to anyone that it will be profitable anytime soon. you have to take a long—term view. perhaps longer. they have

serious plans. scientists at the university of cambridge, in eastern england, have unveiled plans for a research centre to develop new ways to repair the earth's climate. the centre is the first of its kind and has been created because of fears that current approaches on their own won't be enough to stop dangerous and irreversible damage to the planet. this report by our science correspondent, pallab ghosh. a scorched earth where people are poorer and have less food because of severe droughts. there will be more flooding and all the coral has gone. that is what we are headed for u nless we that is what we are headed for unless we do more to cut emissions of carbon dioxide. scientists at cambridge university fear that reducing c02 cambridge university fear that reducing co2 emissions on its own won't be enough. the man whose lead effo rts won't be enough. the man whose lead efforts at the heart of government to combat climate change for 20 yea rs to combat climate change for 20 years is helping to set up a new

research centre. its role will be to repair the damage that's already been done. looking for processes that are scalable, by which i mean processes that can take out billions of tons of greenhouse gases each year. with trillions of tons of ice gone from both the earth's polls, the new centre will look at ways of refreezing them. one idea is to have boats spray seawater into the clouds above the ice to reflect sunlight away from them. another is to develop forests of artificial trees to absorb carbon dioxide, just like real forests, only better. to absorb carbon dioxide, just like realforests, only better. and to absorb carbon dioxide, just like real forests, only better. and some think releasing shiny discs into space might act as a planned trip parasol, reflecting space might act as a planned trip pa rasol, reflecting sunlight space might act as a planned trip parasol, reflecting sunlight and cooling the earth. scientists here leave the earth's climate can be repaired but they say new solutions need to be found and implemented

within the next ten years otherwise it may be too late. pallab ghosh, bbc news, cambridge. stay with us on bbc news — still to come — we'll have all the sport. including why it'll be an english clean sweep in europe — as chelsea and arsenal reach the europa league final. i, nelson rolihlahla mandela, do hereby swear to be faithful to the republic of south africa. after six years of construction and numerous delays, the channel tunnel has been formally opened by the queen and president mitterand. but the tunnel is still not yet ready for passengers and freight services to begin. for centuries, christianity and islam struggled for supremacy. now, the pope's visit symbolises their willingness to coexist. roger bannister became the first man

in the world to run a mile in under four minutes. memories of victory as the ve celebrations reach their climax. this night is dedicated to everyone who believes in a future of peace and freedom. you're watching the briefing. 0ur headlines: the us has carried out its plan to raise tariffs on chinese imports in the past few minutes after last—ditch talks failed. beijing says it will retaliate. the anc is on course to win south africa's general election with a reduced majority, but what now for cyril ramaphosa's plans? let's stay with this now:

with me is sibongile zulu from the democratic alliance abroad. the main opposition party, i should say during these general elections. 0ne say during these general elections. one of the major issues for voters? following are the 2014 general elections and, of course with the onset of the eff, it seemed land would be the most... do land reform? yes, land reform however, now on the ground it seems like economic issues, the lack of economic growth, unemployment, the state of higher education and basic education were the most salient issues with voters. i have read south africa is the most

unequal country by the world bank standards and 55% live in poverty. it isa standards and 55% live in poverty. it is a very devastating statistic andi it is a very devastating statistic and i think it speaks true to the fa ct and i think it speaks true to the fact that some of the policies that have been implemented or not implemented by the anc have not worked for voters. they have introduced the black economic empowerment which was supposed to mitigate some of these structural legacies of apartheid and reduce the state of economic inequality between blacks and whites but what has resulted now is as if it can gap within racial groups and between racial groups so it has not really responded to these issues of economic inequality as we would have liked. let's talk about the inequalities. the anc promised to

crack down on corruption. is there any sign of it? definitely not. just ta ke any sign of it? definitely not. just take a look at cyril ramaphosa's cabinet at least this time around for his cabinet. some of the people implicated in corruption scandals are set to be on this cabinet after this election so i feel thatjust attests to the fact that, although he has said he would deal with corruption, in practice that is not true. jacob zuma has been deployed to campaign on the anc after he was recalled by the partyjust to campaign on the anc after he was recalled by the party just shows that commitment is not true. we have a country full of young people, how engaged are they in politics?|j think they are very engaged. there

is movement from students and they are very engaged. within universities, they have a very robust student representative council ‘s which are usually politically affiliated. however, that does not translate as well in terms of the youth turnout in elections. unfortunately, by looking at the registration numbers, it looks like there was a low turnout of young people, people below the age of 35. if you like, political parties have to do more in terms of enticing younger people to turn up to vote and engaging with them more. thank you very much. here's our briefing on some of the key events happening later.

the parent group of airlines including british airways, iberia and aer lingus returns its first quarter results — investors in iag will be hoping for more of the same after it returned profits last year despite a 30% rise in fuel costs. in london, anti—knife crime protesters will march on youtube's london headquarters. the group including bereaved mothers want the video sharing platform to do more to tackle clips glorifying gang violence. in paris, facebook boss mark zuckerberg comes up against one of his sharpest european critics as he meets french president emmanuel macron who's warned him to do more to tackle hate speech if he wants to avoid regulation. now it's time to get all the latest from the bbc sports centre. hello, i'm tulsen tollett and this

is your friday sport briefing where we start with the europa league and the news that chelsea won a penalty shootout against eintracht frankfurt to reach the europa league final. after it finished 1—1 on the night at stamford bridge and 2—2 on aggregate. first kepa arriza balaga brought his side back into the shootout with successive saves , before eden hazard sealed their place in the final where they'll play fellow london side arsenal, to be played on the 28th of may in the azerbaijan capital of baku but the chelsea manager isn't happy about one thing. we played the match number 61 today. in italy you can play 50, 52 matches but it is a big difference, eight, ten matches is a big difference because there are two months without training so it is a big difference. while pierre emerick aubameyang scored a hat—trick for arsenal against valencia as they moved through to the final winning 4—2 on the night in spain

and 7—3 on aggregate, meaning for the first time ever four teams from the same nation will contest both of the european finals in the same season. iam i am proud of them, how they worked defensively. today, the big players, they can big strikers but with commitment like today, defence also working to help us, it is amazing. roger federer will face dominic thiem in the quarter—finals of the madrid 0pen later on friday. it's his first clay tournament for 3 years but the swiss 20 time grand slam champion survived two match points to beat gael monfils 6—love 4—6 7—6. meanwhile world number three simona halep will play belinda bencic in the semi—finals. the romanian who would move to world number one if she wins the tournament accounted for ashleigh barty to make the last

four and will be looking to claim her third madrid title while bencic knocked out current world number one naomi 0saka. reigning nba champions golden state warriors will be without their star man kevin durant for game six against the houston rockets on friday. the top scorer strained his right calf late in the third quarter. the two—time reigning nba finals mvp limped to the locker room after landing awkwardly following a baseline jumper. the warriors will take a 3—2 lead into the western conference semi—finals but will have to dig deep to complete the victory. the spanish grand prix which is the fifth race of the formula 1 season heads out on sunday. sebastian vettel has stressed that his ferrari team need to start beating mercedes, after the world champions' dominant start to the season. mercedes have taken one—twos in all four races and vettel is 35 points off championship leader valtteri bottas, who is one ahead of lewis hamilton.

and what about this for a mistake, imagine you get an email saying that you've won 2 vip tickets for the champions league final only to find that it was an error. that's what has happened to customers of online retail company zavvi! the company sent an email to each one of their thousands of subscribers telling them that they had won the prize, only to have to backtrack and say that there had been a mistake. what a let down. you can get all the latest sports news at our website — that's bbc.com/sport. but from me tulsen tollett and the rest of the team that is your friday sport briefing. we are often told that school days are the best days of our lives although not everybody agrees. terrible meals, boring lessons may put people off. but in one town in croatia, they have found an unusual

way to shake things up. at first glance, glina's secondary school looks just like any other. but things here are not quite what they seem. the woman on the right is the school principal. the young man on the left is also the school principal, albeit for one day only. here, the teachers have become pupils and the pupils have become teachers, both learning how the other half lives. reporter translation: did any of the real teachers skip classes? translation: two of the real teachers did not show for class, but everything else is going as planned. why weren't they there? we still need to establish why. the aim of all this is to strengthen the relationship between children and staff. some youngsters took lessons, others worked behind the scenes, and the real teachers got the chance to learn a few things. translation: the greatest value of the project is that we teachers are back in school, sitting as pupils for six or seven classes in a day.

we all probably ask ourselves whether we can be focused on lessons the whole time. a couple of teachers had to have their mobile phones confiscated, but otherwise, all went to plan. next year, the hope is they will do it all over again, and the rules of school will be turned upside. tim allman, bbc news. i like that idea. get in touch with us on i like that idea. get in touch with us on twitter. i am, i promise, watching and reading. scientists at cambridge university are trying to open a new research centre to look at some of the old ideas to tackle climate change and today we are asking you what are your ideas? 0ne tweeting that direct act capture removing carbon dioxide from the atmosphere. we will not be able to reduce emissions fast enough

otherwise. another tweets, can we stop interfering with the ecosystem in the first place. another says change the stupid political narrative. lots of people saying it isa narrative. lots of people saying it is a little bit too late. hello there. we've got a couple more showery days in the forecast, before things start to settle down during the weekend, as high pressure begins to build in. low pressure influencing our weather. we started off quite chilly across central and northern areas. the south with a less cold start. a band of cloud through central part stop as temperatures begin to rise into the afternoon, showers becoming widespread with a few heavy, thundering ones. it is a slow moving because the wind is very light.

later in the day, more persistent rain moving to the channel islands and the south coast of england for a while, through friday night. on the weekend, an area of high pressure building in. the blue colour easing away as we import warmer air from the continent. it is a slow process but a drying trend through the weekend. 0n but a drying trend through the weekend. on saturday, a chilly start with northerly winds plenty of sunshine. as the temperatures rise in the afternoon, showers and eastern areas. further west, in the afternoon, showers and eastern areas. furtherwest, dryer. sunny spots we could get 17 degrees. enter sunday, high pressure is right on top of us. light winds indeed. lots of sunshine. some fairweather cloud. most places should be dry.

temperatures responding. high pressure still with us as we head to the start of next week. some of the warmerair the start of next week. some of the warmer air drawn from france and spain. lots of sunshine into the afternoon. perhaps some showers in the morning. a warm day with 18—19, may 20 degrees in one or two places. the week stays largely dry. quite warm with plenty of sunshine but signs of turning cooler by the end of the week as we pick up a north—easterly.
