this is bbc news. the headlines: with new peace talks about to begin, un officials and aid workers are saying four years of war in yemen have left half the population in acute need. they call it the world's worst humanitarian crisis. fighting's thought to have killed nearly 7,000 civilians. thousands more have died from malnutrition and disease. a jury in california has awarded more than $2 billion to a couple who say roundup, the world's most widely used weedkiller, is responsible for their cancer. the german pharmaceutical company bayer bought monsanto, makers of roundup, last year, and it's the third time bayer has been ordered to pay damages. thousands of cases are pending. an american explorer has discovered plastic waste on the seabed of the pacific while setting a new record for the deepest dive in a submarine. he found a plastic bag and sweet wrappers, nearly 7 miles down in the mariana trench. the man in charge of

stadium safety at the time of the hillsborough football disaster in 1989 has been fined £6,5000. -- £6,500. 96 liverpool fans died following the crush at the ground at the match between liverpool and nottingham forest. the former secretary of sheffield wednesday football club, graham mackrell, is the first person to be convicted of an offence relating to the tragedy. judith moritz reports. hillsborough hasn't harmed your career, mr mackrell. isn't it time to resign? though he was responsible for safety at hillsborough, graham mackrell still works in professional football. will you resign from the league managers association, mr mackrell? now, he's the only person ever to be convicted in connection with the hillsborough disaster. on that day, wearing a buttonhole, he was dressed for a special occasion, playing host when liverpool met nottingham forest in the fa cup. but he only put on seven turnstiles for 10,000 fans. a huge crowd formed. police opened a gate, but supporters went on to terraces which were already full. 96 died.

thejudge said, while mackrell‘s actions set the scene for the disaster, they weren't a direct cause of the deaths. he fined him £6,500. our 96 are dead and all it's worth is £67.70 each. shameful. it's just another day in the life of hillsborough where, yet again, the families have been shafted. i just really don't think that they've got any regard for what the families have actually been through. this is an original match programme from the fa cup semifinal. you can see graham mackrell‘s name here on the back. and inside makes interesting reading as well. there's a letter from the sheffield wednesday chairman, bert mcghee, who talks about hillsborough as the perfect venue for all kinds of important matches. he says it's a stadium that befits such occasions and the large

crowds they attract. the next day, mackrell was one of those showing margaret thatcher around hillsborough. the match commander, david duckenfield, was there too. his recent trial ended without a verdict. a retrial is being considered. judith moritz, bbc news. now it's time for the travel show. this week on the show: the remnants of france's nazi occupation. in some ways, this place is immaculate. it feels in some areas as though the germans have just stood up and walked out of here. and a bird's eye view of california. it's called the ‘jug' when you do this. he grunts. that one wasn't so good! it's incredible up here. the normandy coast in north—west france.

next month marks 75 years since it saw the biggest seaborne invasion in history. 156,000 american, british and canadian troops landed along five of these beaches on d—day. this was the bloodiest flash point of d—day — 0maha beach, where 43,000 american troops stormed the beaches straight

into the teeth of the german guns — and really well defended positions here, as well. it took ten hours of brutal fighting before the beach was secured. looking around today, it is a really peaceful scene. it is incredible to imagine the horror of that day. there are museums here, but on the actual sands there is no evidence left, except for these. slowly being reclaimed by mother nature now, these bunkers formed part of the atlantic wall — a series of german fortifications which stretched from scandinavia along the dutch and belgian coasts and all the way around france. designed to repel an allied sea attack, many of the bunkers are still in place. like this one, hidden behind the beach huts and under the dunes on sword beach, metres from where the

british forces landed. has sentiment about structures like this changed since the end of the war to today? would people after the war have been so keen to commemorate, do you think?

but for the most visible bunker in the area, you have to go inland slightly, into the town of quistreham. inside, its five floors have been restored and put to use as a museum showing what life would have been like inside this thick concrete shell. so, the story goes that this place wasn't liberated on d—day, it was three days later that british forces came up, thinking this was an amunitions bunker, a storehouse, and when they blew the doors open there was a voice coming down from upstairs saying, "tommy, come up, were waiting for you!"

upstairs, lo and behold, 50 german soldiers who had been hiding out. and they said, "well, no, you come downstairs, actually." there is no lift to the roof. you climb in the same way that the soldiers stationed here would have done. how anybody did this under fire, absolutely... from up here you can see sword beach, where the british arrived. further along you've gotjuno. the point out there where the canadian forces landed. further along you've got gold, 0maha, utah. it's quite an extraordinary sight. in some ways, this place is immaculate. it feels in some areas as though the germans have just stood up and walked out of here, but it's not the only bunker in the region that has been restored. these ones, not far from dunkirk, have become an art project. some have been covered with slogans and another has been decorated with hundreds of shards of mirrored

glass, so when the sun shines it becomes a beacon. and here, in lorient, just across the peninsula from the landing beaches, there is this, the keroman submarine base. it was the biggest structure in the atlantic wall. in fact, it's the biggest germanic construction outside germany. there's enough space for 30 submarines inside. this place was designed to withstand allied bombardment and, looking around, it was pretty successful, but the result is, years later, it's almost impossible to destroy. so, after a long time spent scratching their heads and wondering quite what to do with this behemoth on their doorstep, the city of lorient decided to put it to rather a different use. some of the site is already used by sailing clubs and people come here for guided tours at weekends, but this spring, a company called hydrophone moved into one

of the submarine bays here and turned it into a studio space and a concert hall, though it's virtually impossible to remove the history. that's impressive. that's a door. that's a door?! a door, yes. a big door. 15 metres. with something like this, this is not an optional design feature, is it? no. this isn't moving! yes! it's very nice for the people, when the people arrive here, they say, "wow!" every people. "wow, that is a big door!" a big door, yeah.

this place has quite a dark past. has there been any controversy or sensitivity around using this space for a modern purpose? in the past, these fortifications held too many traumatic memories for them to be put to use in this way. but there is a new generation

in charge now who have a different relationship with the wall. oh, wow! look at this. and this is the concert hall. yeah. i think it's lovely that this space, that was built for not so good a purpose, is actually now being used as a lovely cultural centre for people to enjoy themselves. yes, it is motivation for us. the difference between the past and the future here, it's a motivation for us every day. it's like a new life. a new lifeline, exactly. and if you are thinking of heading to northern france this summer, here are some travel show tips that mightjust come in handy.

france hosts the women's football world cup injune and five of the nine host cities are in the north. reims, in the heart of champagne country, is arguably the most eye—catching of those venues. there can't be many better ways to prepare for the opening group games than a tour of the vineyards and a good look around the city's incredible gothic cathedral. the region's not bad for surfers, either. the stretch of coast between quimper and quiberon is a highlight if you're looking for some waves, but want to avoid the crowds. la torche, meanwhile, in south—west finistere also has great ocean rollers, but if you are going there in peak times it is worth getting up early to get the best all to yourself. this year, lille hosts lille 3000, a series of events, performances and exhibitions that take over the city once every three years. this time, the theme is el dorado — the mythical city of gold. look out for the three big weekends that mark the cornerstone of the celebrations. the first takes place next weekend, so you might have to move fast

if you want to be a part of it. and if you've been hooked to the new game of thrones season, then the new exhibit at bayeux might just be the thing. the game of thrones tapestry arrives in town in september. it's 80 metres long, it's been embroidered by a team at the ulster museum in northern ireland and it depicts scenes from every episode of the fantasy tv epic to date. if you're not a fan, then the world—famous 11th century original work is pretty good too! still to come on the travel show: mike's in california, seeing the impact of climate change in some of the world's tallest trees. temperatures are increasing, it's drying things out as temperatures get warmer and that's a big consideration for these particular trees because they need so much water. so, don't go away.

this week, i've been exploring northern france. this is the brittany coast, not far from lorient. the countryside around here is absolutely glorious, and green, especially on a beautiful day like today. if i can find it, there's somewhere i want to show you. many visitors to france will have tried crepes, the original french street food, but did you know they actually hailfrom brittany? this looks like it! so, which is the best crepe to order, do you think? so, the crepe she's making me is actually a kind called a galette and, while you might be more used to having yours with chocolate spread or ice cream, these bona fide local ones are usually savoury and each

province makes its own specialty. ok, so basically, a galette is a savoury version of a crepe, and a galette is definitely what you want to go for if you come to this part of brittany. it looks pretty good. we're hopping to the other side at the atlantic now to meet some

of the giants of the natural world. california's redwood trees are the tallest living things on earth and amongst the oldest too. but they are far from invulnerable. mike corey's been to big sur to find out why climate change is causing some to fear for the future of this amazing species. here in western california, there are complex beings that have lived for over a millennium. redwood trees have become an icon of the state, but some fear that our changing climate might threaten their survival. so i've come to the most southern tip of their range, where change could hit them hardest to join a scientist who's been working here to try and find some answers. it's absolutely amazing being out in the forest. i absolutely love it.

i'm listening to the birds, watching the sun move through the canopy, it's beautiful. i feel lucky to be able to be out there just amongst the trees, full of anticipation for the day to come and being able to go up into the canopy and, hopefully, see something that i haven't seen before. there's a presence to them that's really impressive, it's palpable when you're out there. and today, we'll be climbing this. it looks like it's ok. pretty good. so, ready for the bestjug yet? yep. it's called the ‘jug' when you do this. that one wasn't so good! 0k. that's a lot more work than i thought it was going to be! just wait till you get to 70 metres!

so these are coast redwoods. they're the tallest tree species in the world, reaching currently about 380 feet tall are the tallest ones. they are incredibly tough and resilient. they‘ re really important ecologically. they support the habitat and provide habitat for a lot of plants and animals and they're also just incredibly beautiful and iconic. so, i've been here trying to get a better understanding of how they're responding to climate change and how they might respond to future climate change. and how are they responding to climate change? so as the climate changes, temperatures are increasing, it's drying things out as temperatures get warmer. that's a big consideration for these particular trees because they need so much water, it's affecting their water balance and their ability to transfer more water to the tops of the trees. but now it's time to get to work. there we go. so, first we need a sample

of the tree's core. this is the halfway mark. when you get to the ground, we'll be able to pull that spoon out with the core on it. and so all the hidden secrets beneath the bark will be ours. yes! the knowledge will be ours. earlier on, anthony showed me some of those secrets this tree had already revealed. wow! these are the rings here? yeah, yeah. so each one of those is an annual ring, one year's worth of growth you can see here. so it really only grows a couple of millimetres a year. yeah, yeah. and sometimes it is even less than a millimetre a year, depending on how the conditions are. so we are back hundreds of years right now. yeah, yeah. once we polish this up and sand it and get a better view of the rings, there could be 100, 200, 300, 400, 500, 600, 700 maybe years here. wow. so this section up here hasn't seen sunlight for 600, 700 years. yeah. it's an amazing archive.

all right, so i have one end of the tape measure. yeah. we're doing the circumference measurement. yeah. so wrap it all the way around there, underneath the tubing there. 0k. so we are at 7.81; metres circumference. that's a big tree. it is a big tree. 7.81; metres around and we are five metres off the ground. the next plan is to go up to the top. all right. i will put that in my notes. upwards we go. to the top! this redwood stands at over 70 metres tall. climbing redwoods is forbidden in most places, but in this reserve we have special permission and what a privilege it is. 0k, a0 metres.

i can't get over how beautiful this tree is. we have got up to the canopy, so there are burn marks on this tree at a0 metres, which boggles my mind. it's incredible up here. and, as we inch upwards, jug byjug, i'm faced with more scorched bark. anthony told me that wildfires are another threat these trees are increasingly facing in the modern world. a bird's nest. i don't think there's anybody home, though. there's nothing else like this on the planet. i'm getting an appreciation for that right now. i'm also getting quite sweaty! it's not easy work. with anthony already at the top collecting samples, i make my final push upwards.

this view is definitely one of the wildest, most incredible views i have seen in my entire life. i can't believe we are 71 metres off the ground right now. condors get this view. condors and us. it's incredible. this is 700—years—old, which is before the colonisation of america, before the taj mahal, before machu picchu. it makes me feel like a speck of sand in a sandbox — insignificant. yeah, it's a pretty humbling experience, isn't it? if the climate change conditions dry things out sufficiently, than they might start to feel some impacts, they might not grow as well, they might not get as tall. they might, in the future, even start to die back and that is what we are trying to figure out.

do i feel the tree shaking a little bit? yes, it's moving. 0k. this is a normal thing, i'm assuming?! right, well, that's it for this week. coming up next time: lucy is in new york for a special look at a brand—new museum dedicated to one of the world's most recognisable names. liberty island receives nearly 11.5 million visitors each year. on a busy day, as many as 25,000 people come over and, right now, we've got it all to ourselves. this is incredible! and we go off—grid in norway to meet the man with an island all to himself. when we came around the point here and we turned off the engine and said, "well, this is it, this is the place". 0ur dreams became reality. that looks great. meanwhile, you can catch up with us on social media. just search bbc travel show on any of the major platforms and feel free to tag us in your travel posts too. for now, though, christa larwood
