good to have you with us. a warm welcome to the programme — briefing you on all you need to know in global news, business, and sport. tributes are pouring in following the news of the death of niki lauda — so we'd love to hear your stories and memories this morning. do get in touch, just use the hashtag bbcthebriefing. let us focus on that right now. tributes are coming in to the three—time formula 1 motor racing champion, niki lauda, has died at the age of 70. he was a winner for ferrari in 1975 and 1977, and for mclaren in 1984. but more than that, he came to define grace and courage after being badly burned on the racetrack. a family statement said he died

peacefully with them by his side. jo wilson looks back on his life. niki lauda excelled and somehow survived in a desperately dangerous era. he defied his wealthy family's orders to be a racing driver. with ferrari, lauda dominated formula 1. already world champion in 1975, more glory seemed certain. this was his car at the 1976 german grand prix. other drivers had rescued him from the wreckage. this was lauda six weeks later, wounds barely healed, but ready to race again. he'd heard the doctors predict he'd die from lung damage. he'd implored himself to fight. when that feeling came you get a big fright, you know, you're really worried and frightened that you're going to die. and then that means you start everything possible to keep you going and you can't start your body, because the body doesn't react.

you only can start the brain. you hear voices, you ask, for example, names, why is he here and why is he not here? the thing is to keep the brain working. if the brain works the body starts to work sooner or later. in 1977, he was world champion again. the championship was lauda's. fourth place at watkins glen in the autumn was enough to regain the world title. a staggering feat, acknowledged when the bbc reviewed it at the end of the year. regaining the drivers‘ world championship only 1a months after his crash in germany, niki lauda wins the bbc trophy for the outstanding overseas personality of the year. applause. lauda was champion driver again in 1984, a victory for mclaren to go with the two titles that he'd won for ferrari. later he held managerial roles

in formula 1, notably at mercedes. niki lauda lived to inspire new generations in the sport which so nearly claimed his life decades before. even though the news broke overnight in europe the tributes are coming in. the former moto gp motorcycle champion casey stoner has tweeted... this one from mclaren motorsport... and the former champion jenson button has simply tweeted:

as i've mentioned, we would love to hear your memories and your tributes as well. do send them in and we will mention them later in the programme. scientists believe that global sea levels could rise far more than predicted, due to accelerating melting in greenland and antarctica. the long—held view has been that the world's seas would rise by a maximum ofjust under a metre by 21 hundred. this new study, projects that the real level may be around double that figure, leading to the displacement of hundreds of millions of people. caroline rigby reports. these vast icy landscapes are some of the most remote on our planet, but they play a crucial role in shaping the future of life on earth. global warming is causing ice sheets in antarctica and greenland to melt, but some scientists believe climate models have underestimated

the likely level of melting this century and, in turn, the extent of sea level rise. now a new study, drawing on evidence from 22 leading researchers, has warned of the situation could be far worse than generally accepted. in 2013, the un's intergovernmental panel on climate change predicted that by the end of the century global sea levels would rise by around one metre. but researchers now suggest seas could rise by twice that amount, that's if unchecked carbon emissions cause the world too warm by 5 degrees celsius, other than the 2 degrees scenario consistent with the paris agreement. the consequences of this on coastal communities and ecosystems would be catastrophic, with the poorest countries set to be the hardest hit. almost 1.8 million square kilometres of land could be lost and up to 187 million people displaced.

bangladesh and the nile delta would be particularly badly effected. while major global cities, including london, new york, and shanghai, would come under threat. it's not like all of a sudden it's going to submerge entire cities, it will just sort of start cutting away at significant parts of them. for instance, lower manhattan, unless they build defences, a good chunk of that would be underwater. yes, a good chunk of bangladesh. the dutch, who are very good at protecting themselves, would have to get scurrying and build fast. this is a situation we have to avoid. the authors of this report with the likelihood of this level of global warming and associated sea level rise atjust 5%. in essence, a worst—case scenario. but with such profound potential consequences for humanity, they are urging politicians to reduce carbon emissions urgently. caroline rigby, bbc news.

he seems to suggest she could be awarded public construction contracts in return for political and financial support. mr strache resigned on saturday. but that wasn't enough for his coalition partner, austria's chancellor, sebastian kurz. he said the far—right interior minister, herbert kickl, should be sacked as well, as he was unfit to oversee the investigation into mr strache. translation: all of this has, in my opinion, led to a conflict situation. it would have been better if, along with heinz—christian strache, the interior minister resigned as well. that would have brought a watertight resolution of this. but he didn't take this step. but the freedom party said that if mr kickl was fired, all its other ministers would quit in solidarity. mr kurz has suggested filling the empty posts with technocrats, but other opposition parties say they don't agree.

translation: i had a very good and in—depth conversation with the president. i told him that, in my opinion and in the opinion of the social democrats, only an interim government made up from experts for all of the government positions, including that of chancellor, could restore calm and stability and resolve the very tense situation in austria. and mr kurz‘s own future could be at stake. he now faces a possible vote of no confidence in parliament, a step which could lead to even more chaos. bethany bell, bbc news, vienna. now our top business story. the us government has eased some of the restrictions imposed last week on the chinese tech firm huawei. it means service and support will continue for existing phones — although huawei is still prohibited from buying american parts and components. so what does this delay mean for huawei? our tech correspondent dave lee in san francisco explains.

this move has scaled back a few of the restrictions announced by the us commerce department last week, but it has certainly not made the problem go away. huawei has been granted a temporary license to buy american—made goods. but only for existing uses such as maintaining networks or providing software updates to huawei smartphones. it will last for just 90 days, however, after that a full block will come into place — a block that threatens to completely destabilise huawei's ability to do business nutjust in the us, but globally. it can also prove extremely damaging to major us firms such as intel, qualcomm, broadcom and other chip and technology providers to the chinese giant. when huawei provided a list of its top global suppliers, 33 were american firms. they stand to lose billions of dollars if this ban is enforced in full.

us intelligence agencies say such drastic moves are necessary to protect national security. china argues it's a plot to pile on the pressure during ongoing trade talks. either way, companies in both countries are set to get hit hard. dave lee, bbc news in san francisco. we will have further analysis on huawei in business briefing, that is injust under 20 huawei in business briefing, that is in just under 20 minutes. spain's parliament will reopen today however not without controversy. five jailed catalan separatists who were elected as lawmakers in last month's national election will be allowed to attend but with a police guard. four will be sworn at the congress, while a fifth will take his seat in the senate. all of them will then return to prison according to a decision made by spain's supreme court. our correspondent guy hedgecoe is in madrid.

extremely unusual circumstances. just talk us through the day ahead. ‘s rate. in about four hours the 13th legislature of spain's modern era will open. the 350 congress members will take their seats. among them will be those four congressmen you mentioned, those catalan politicians who are in prison, are on trial, facing charges of violent rebellion. they will be among those who take their seats. there will also be that senator as well taking his seat in the senate. so it is going to be very unusual because of those catalan politicians and their involvement in the day's events. they will be able to take their seats. what we don't know is if those four congressmen will be able to ta ke those four congressmen will be able to take part in parliamentary activity, because there is a good chance that even later today the parliamentary residing council will suspend them from parliamentary activity —— presiding. so there

won't be able to actually take part in parliamentary business. in terms of those five separatists that have been jailed, of those five separatists that have beenjailed, as of those five separatists that have been jailed, as you say, today, they're going to be attending those of various events, what does the future look like for them, those five individuals? well, they have been on trial since the middle of february facing these very serious charges, violent rebellion, sedition, misuse of public funds. in the trial is expected to end sometime next month injune, possibly mid or late june. sometime next month injune, possibly mid or latejune. we don't have a set a date for that. with a verdict than expected robert lee not until after the summer. so at least september. —— probably not. we don't know what the outcome of the trial will be. it is very controversial. there is a possibility they could face a lengthy jail there is a possibility they could face a lengthyjail sentences if found guilty. all right, we have got to leave it there. we your time. guy hedgecoe, who is based on madrid.

become the world's newest nation. it was a bloody birth for a poor country and the challenges ahead are daunting. you are watching the briefing. our headlines: the three—time formula 1 world champion niki lauda has died at the age of 70. scientists are warning that sea levels could rise far more than predicted due to accelerating melting in greenland and antarctica. the rise of nationalist, eurosceptic parties is keeping the eu establishment awake at night as it prepares for european elections at the end of the week. in germany, the far—right party afd is expected to make gains, but it is likely to be dwarfed by the green party. with more on the rise of the german greens, here is our berlin

correspondentjenny hill. ploughing through germany's political landscape, the green party. staring up the centre ground. for this farmer, the greens can be trusted to safeguard the environment, and that, polls suggest, is now the most important issue for german voters. translation: i was surprised. the focus in elections has always been on immigration. i'm glad. i hope it's a proper change of heart, and not just a flash it's a proper change of heart, and notjust a flash in the pan. germany is failing its own targets on emissions. angela merkel admits she feels pressure from europe's youngsters to find solutions. once hailed as the climate chancellor, the government is still squabbling

over environment policy. this is basically, you know, the legacy of the nuclear incident in fukushima, yea rs the nuclear incident in fukushima, years ago, she was the one behind this very dramatic, you know, you turn in german energy policy, which meant going out of nuclear well at the same time also going out of coal. that hasn't gone particularly well. then there is germany's enduring passion for the combustion engine. this may be a country of recycling and renewables, but it is also the country of the car. of course, there is two parts. i think it is ok to have both interests, the carand it is ok to have both interests, the car and the environment, and there must be compromise. translation: they make it all about the cars, this man says, but really our problem in the world is overpopulation. no—one tells the truth about that. current solutions are politically divisive. driving bans, i proposed co2 tax, it is fuel

to the far right. rescue diesel, this poster says. anti— migrant, eurosceptic, the party denies man—made climate change. it is controversial, but it is expected to make electoral gains. these elections are significant because, in many countries, germany included, they are really about one story — they are really about one story — the clash between nationalist parties and european establishment ones. but in germany, another narrative is springing up as well, one which says the elections aren't just about the future of europe. they are about the future of the planet. new divisions, fresh alliances. as europe reshapes its political, perhaps even its literal, environment. our
