the hosts france a 2—1 in paris. the american captain proved to be at the difference, she scored an impressive goal, france did get a consolation late on but the usa saw the game and despite a late claim for handball. the semifinal against the usa will be in lyon. you have to give it up to the french team, i think they are plagued out with the ball today but we we re plagued out with the ball today but we were so plagued out with the ball today but we were so good defensively, so strong. we had so much it hurt, we took our chances. this team are just unreal, and unreal amount of heart. england is reaching the semifinals means there will be a pretend women's team at next years olympic games. britain last play in the 2012 london olympics. but the british tea m london olympics. but the british team will compete in tokyo, there will be 12 nations feuding women's

size. england fans will be keeping a close eye on pakistan's world cup match afghanistan. afghanistan won the toss, chose to bat, lost two wickets early on. afghanistan have just lost another wicket, they are struggling at the moment, there are 126-5, struggling at the moment, there are 126—5, from 28 overs. pakistan will move above england into the semifinal places with a win. england play india tomorrow. in at the women's one—day tour match england are 187—3 with 22 overs left. england knit netball coach, tracey neville, has told the bbc this use world cup will not be her last in charge. neville had said that she would step down to have a family. this is not my last world cup. i

think the girls want to do it for themselves, they dug for themselves la st themselves, they dug for themselves last year. i want them to do it for themselves because they so deserve that. i can only focus on this netball world cup and for the girls, i know they want this world cup as well. if they want to do it for me, that's fine. but we are doing for everything we have worked towards over these last four years because they have been absolutely outstanding in their professionalism to it at this point so far. manchester city striker, said aguero, had a hand in both goals as argentina set up a semifinal with brazil by beating venezuela 2—0 na, america match. aguero's low drive was flicked into beautifully by marchioness, a lovely finish. when did not create much and their goalkeeper spilled a shot for a tap in. that is all your spot for now,

110w in. that is all your spot for now, now it is time click. 999 — this is a climate emergency. and this week we have greener, cleaner buildings, robot boat exhaust sniffers, and artificial trees. i want to share with you a fact that i hadn't fully understood until i met climate scientist ed hawkins last year. now, i'd known that our weather was getting worse and our sea levels were rising, and i'd known that global warming was happening because we were emitting carbon dioxide and methane into the air at a runaway rate, but what i hadn't

fully understood is this — simply reducing greenhouse gas emissions will not bring global warming under control. for every ton of co2 that we put into the atmosphere, the temperature goes up a little bit more. in order to stop global warming, we need to do something very drastic indeed. if we end up in a world where our emissions are net zero, we're not increasing the amount of carbon dioxide in the atmosphere any more, then that will stabilise global temperatures at the point at which we do that. but it's not realistic. to reduce global temperatures, we would need to somehow remove carbon dioxide from the atmosphere. now, there are already ways of capturing co2 at source — on its way out of power stations, for example. but this doesn't get it all, by any means. what you need is something to pull

co2 back out of the air. what you need is something like this. it's called the artificial tree. the air passes through these filters, which are made of a very special material because the co2 actually clings to this material as the air passes over it. now, once these filters are saturated with carbon dioxide this whole thing moves down into a container of water where this particular material releases the co2 into the sealed container and then, congratulations, you've captured yourself some co2 from the air. this is the brainchild of klaus lackner, here at the aptly named negative emissions centre at arizona state university. they realised very early on this was a waste management problem. we are dumping co2 into

the atmosphere and it just stays there. so was very clear to me in the early 90s that sometime in the 21st—century we will have to stop emitting. klaus was the first scientist — back in 1999 — to publish a scientific paper suggesting carbon capture from the air was a feasible way of combating climate change. the problem was no—one seemed to be listening. if you look at the climate change problem, in the ‘90s we had models which told us it's happening, but you couldn't really set out in the real world, except with a microscope. in the 2000s, you could measure it. it was happening. in the teens, now, you can see it happen, even as a non—expert. climate has changed. in the next decade, as it grows out of the noise, it becomes loud and clear and it starts to hurt. and once it hurts people say "what will we do about it?" klaus argues that since we are failing to meet our targets

for co2 emissions, carbon capture from the air is now unavoidable. and now people are listening, as technology has recently received commercial investment. we have put so much co2 in the air that we actually have to come back. so we call ourselves the center for negative carbon emissions because we are thinking about having a period in this century in which we will have to take 100 ppm back. now, that is more co2 than the world emitted in the 20th century. how many of these do you think we will need? a lot, a lot. now, these are very small. but go to the size of a shipping container, if you wanted to actually match current emissions you would need 100 million of them. right. now, these are bigger than that. but 100 million sounds like a horribly large number until you start deconstructing it. we build 80 million cars.

shanghai harbour is sending out about 30 million full shipping containers every year. so i would argue that as far as industrial scale goes, this is large, but not outrageously large. so who would you suggest pays for these in the future? ultimately, it's part of the energy consumption, so you the consumer, and some form or another are on the hook. and as people around the world started to reach the conclusion that carbon capture is needed, a start—up scene is beginning to grow — with differing approaches. because co2 is everywhere, it doesn't really matter where you put your devices. and in iceland, caerix has something very useful — green geothermal power. using this, they claim to be able to capture way more carbon than klaus's artificial trees.

and once you've captured the carbon, the next problem is — what are you going to do with it? there are so many r&d projects underway trying to make use of the to make use of the co2, so that it's notjust rubbish, but we can actually make something valuable from it. we can use the co2 to create drinks, beers or soda or whatever. we can also use co2 forfuel production. there are also currently studies ongoing to see if we can somehow use the co2 as a building material. yeah, in the future we may be able to lock co2 into concrete. although the amount of rock we'd create has been estimated to cover a landmass the size of egypt. and, in fact, to do this any other way also requires a scale that is pretty unimaginable. you could say we can do it with trees and real forests,

and you can calculate if you wanted to do the same 100 million of these these units in forests, or any agriculture, any photosynthetic systems, you suddenly realise that the land area or the area you need is larger than current agriculture. you know, pastoral lands, fields, everything added, we would need more than that. welcome to the week in tech. it was the week where a city in florida paid almost £a00,000 in bitcoin to get its data back from ransomware hackers who'd locked up their computers with malware. engineers at toyota built a world record breaking free throwing basketball droid. 03 managed 2020 executive successful shots.

this new form of deepfaking is the work of samsung's ai centre at imperial college london. deepfakes can now be generated using just one image of a subject before the ai algorithm goes to work. # halo... this is quite a scene. the dancers here are being choreographed by artificial intelligence, which has learned from moves created by a leading choreographer — and it's quite something. wayne mcgregor has been running his dance company for 25 years, so has an archive perfect for thejob. wayne is actually here today, but he seems to be focusing on perfecting the moves rather than designing a whole dance. a computer algorithm is analysing hundreds of hours of his dance creations, sparking new personalised routines ready for a show in la next month.

so how does he feel seeing what the technology musters up? you see it on the screen and it's surprising, it's something you've not seen before. you can't quite work out how your body can do that and then the dancers in the room have to translate it, they find, they have to look at it and find a way of themselves embodying the physicality. the imagery used could improve over time, but there is also a reason for the imperfections. this has been the creation of the man behind google cardboard, who greatly values technology as a tool to enhance — not reduce — creativity. of course the dancer, the choreographer is the artist and the ai is there to stimulate creativity and not to replace it. we display some stick figure just to display the whole output of the algorithm, but we are also making a rendering which is something in between abstraction and the skeleton. and if it was too perfect then it would look like a video and it would be less stimulating

for the dancer to be inspired. and as well as the idea of immortalising talent and teaching, there seems to be some other added value. what it's doing is supplementing, enhancing, dealing with data in a way that we couldn't deal with it, offering us opportunities that we would never be able to see. and so in a way it becomes like an 11th dancer in the studio with you, it's a kind of a creative partner rather than one that's replacing your kind of creative gifts, if you like. the other thing is, it's really important, it's about the dialogue between machine and body, between the thinking body and the thinking machine. so was not ever that we set the system going and just learn the choreography, that's not interesting to us. these dancers make every move looks so graceful, so it's hard to imagine a bad outcome being created here. but how do they feel

about being taught by ai? usually you have wayne come in and he either gives us creative tasks himself, which could be based on anything, it could be a poem, it could be audio inspiration from a track, but to have these really intelligent quick systems that kind of generate movement that then we have to learn from, an ai system, it's very different. whatever the google stick men are demonstrating, just take something from it. you know, we don't spend too long analysing. it's really find each other. it's just whatever you see, take something from it. at the moment it doesn't understand momentum and physics and gravity, so it makes us move our bodies in an incredibly different way. you know, we have a typical vocabulary, each and every one of us, that we kind of go into that we try to strive away from, and i think that this helps us do that. so while its early days for this technology and it doesn't seem to be making the real—life choreographer redundant, maybe, just maybe, artificial

intelligence could push creativity to a whole new level. that was lara. now, one often unseen cause of air pollution is shipping. the enormous cargo vessels which criss—cross the world produce enormous amounts of sulphur and nitrous oxides as well as particulate matter. by some calculations, one large container ship can produce the equivalent of tens of millions of cars' worth of these pollutants. but it is a field where much more measurement is needed to truly understand the scale of the problem and what can be done. paul carter has been to denmark to investigate how authorities there are using tech to better understand shipping and the pollution it causes.

this sleepy remote part of denmark may not look like it's at the cutting edge of emissions detection and enforcement. but looks can be deceiving. the danish maritime authority, in partnership with the european maritime safety agency, are using drones like this one as the latest weapon to detect and identify ships that are breaching eu regulations on emissions. this aircraft is equipped with a range of detectors and sensors, as well as 360 and infrared cameras, to identify ships and effectively sniff their emissions, by flying through the plume of smoke they leave behind. i am standing on the takeoff and landing zone for the drone that they use here, or rpas, to actually give it its correct term — it's out behind me somewhere finding a ship to sniff, for want of a better term, and i'm not sure if our camera can actually pick it up, but along the horizon there is a yellow band which is actually the pollution that these ships are emitting.

if you can imagine what it was like before these regulations came in, and that is exactly what this aircraft is trying to detect. so this is a very innovative project, to protect the environment. how does it work, what we try to do is take as many measurements as possible of the sulphur content of the plume of the vessels, and this type of drone is adding proof of that infringement. because up to now what happened sometimes is that they were changing fueljust when entering the port, so this type of drone allows us to also take measurements while they sail. now, it is going to be coming back in to land soon, and to be honest, i don't really want to be stood here when it does, so i'm going to make a sharp exit. it is piloted by two people from a ground—based control centre. one flying, and one monitoring the payload, as well as a team of ground—based

engineers and observers. what's it like to fly one of these? it is quite good fun, it is different, i used to fly helicopters, so it is very different in that respect. but it is, in many ways as well, there is many similarities. drones react the same way as a helicopter would do, so then i can use experience of the helicopter pilot in this type of industry. it is nice to be able to do something for the environment as well. we can see when it's polluting a lot, then you can see the black smoke, but most of the time you don't see it, especially if the wind is pushing it down onto the side, you might not be able to see it. but we also have extra tools, like an infrared camera to be able to see it, it might help us sometimes as well. so we have a sensor which monitors the co2 and the n02, and we also have the payload camera which you use to be able to see where you are going. the rpas, or remotely piloted aircraft system, is detecting for a wave of pollutants. all the data recorded is shared

directly with the host member state, and also with emsa. now we can extend our reach by a huge margin, by flying these drones over the ships and collecting samples of the emissions, and then calculate back to how much sulphur is in the fuel. are they breaking the rules, or are they not, and then we can follow that up with actual inspections when the ship comes into port. and here it is coming into land, you can see it swooping around slightly just to accommodate for the wind, it is quite bizarre to think that even just a couple of minutes ago, that was us back out there on the horizon, it has been out there for the last hour, hourand a half, inspecting any ships it has come across, now it's coming back in to land for a well—earned rest. we are the first movers with the type of technology used in this way, but as it gets easier and the regulation behind it matures, i think you will see this all over the place —

and it is notjust for sulphur emissions, you could do so many things on sea, and that's what we are trying to do, we are trying to extend our reach, where can we go and enforce the rules that we are trying to enforce. denmark are the first eu member state to use this technology, but as regulations and legislation continue to emerge, soon no ship will be safe from similar sulphur sniffers. ok, we're off to switzerland now for an innovative way of building homes more cleverly and more sustainably. dan simmons has been to see some unusual buildings, and the robots and very old wisdom used to build them. in zurich, the experimental odd—shaped dfab house has recently opened its doors. it has been partially built

by robots, and the lack of any tea breaks isn't the only cost saving. this flexible mesh mould allows for fast, creative design. the bots build the wall from digital models. these 1—offs would typically mean more materials are wasted than standard straight walls. but doing things this way results in hardly any material waste. elsewhere, these dynamic casting machines create both load—bearing functional supports and lighter facades, while 3d sand printers produce ultralight ceiling slabs. again, all with minimal waste. and that's important. because you may be surprised to learn that we are just a decade or two away from running out of materials to build with. we are rapidly running out of resources. as funny as it may sound, we are even running out of sand to make concrete.

this particular floor actually is printed out of sand, but other materials could be compressed dirt, basicallyjust dirt locally found on site, or clay, or a combination of materials like that. these lighter and more varied choices of material will help us save the planet's resources, and to test what will and won't work, they need a huge sandpit in which to play. the university is home to one of the biggest robots, if you like, in the world. this is a large, well, house building plant. it has four or five of these huge arms to create different things, this is a floor that's in progress. the only problem is that once they have built it, they've got to get it out these doors. but look again at those ceilings and floors. they are more important than you might think.

using different materials is all very well, as long as they are as strong as concrete, right? well, no. in fact, a change of design inspired from europe's stunning architectural past, is solving that problem. just like the flying buttresses of gothic cathedrals, arched slabs can support a lot of weight without requiring steel reinforcement. by studying traditional vaulted construction methods, researchers then use 3d printing to make super—thin floor slabs that can withstand heavy weights. what all these designs have in common is that they have strength through their geometry, through their design. they spread the weight of various areas and can take more weight once people are on them and support them, often with less material. in this example, the form that's needed to create the bridge is just a piece of material like this. rather than building up a huge support structure and pouring

the concrete over the top. it uses less material, as do the slabs that the university have created now. through a different geometry, they can save up to 70% of the concrete needed. the upshot could be buildings that are just as strong as today's, but that end up weighing half as much — because the floors alone usually make up about 80% of a building's total weight. researchers say they comply with all swiss and eu building regulations, although the new designs are yet to be signed off. that was dan, and that's it for click episode 999. i know! we've been on air every week for over 19 years. and next week is our 1000th programme. to celebrate, we're doing something very special, and you're all invited.

for the first time, rather than us deciding what you watch, you will be in the driving seat. because for our 1000th episode, the bbc is letting us pioneer a completely new way of making tv. we've created an interactive world of stories for you to explore however you wish. more than a year in the making, from the self driving capital of the world — phoenix, arizona — to magical malawi to meet the inventors using ai and ancient technology to solve everyday problems. combining the production techniques of videogames with that click storytelling that you know and love, you will be able to shape our show. and there'll be wizards. we've all worked really hard on this, and we are incredibly proud of the result. we hope you enjoy it too — that's next week.

thanks for watching, and we'll see you for click 1000. hello. rising heat and humidity are the main features of the weather today across many parts of the uk, particularly for england and wales, not quite as hot for scotland and northern ireland as yesterday. this is the picture taken earlier this morning in west sussex, beautiful blue skies there, looking across the english channel. today could see temperatures as high as 3a celsius under the blue skies, and with all that sunshine, the hottest place towards the london region today. yesterday we had temperatures of 30 celsius across scotland, it won't be quite as warm today. we have some heavy, thundery showers pushing across parts of northern ireland and south—west scotland, in particular, one or two of them into

the north west of england too. further south, across england and wales, we are looking at a dry day, with southerly breezes developing, top temperatures will be about 33—34dc. quite widely in the low 30s for england and wales, typically the mid 20s for scotland and northern ireland. into the evening, a fine one for many across central and eastern parts of england but some heavy showers for northern england and scotland. heavy showers and thunderstorms push their way out to the east through tonight, with something fresher following on from their west so not quite as hot and muggy as it was last night across the north—west of the uk, overnight low of 16—17 towards the south—east. it could still be quite a humid start to the day on sunday, but in general, sunday will feel different to today, a much fresher day to come with a mixture of sunny spells and a few showers. the heat with us, and across france today, will be pushed further east into europe so it will be germany and poland that will feel the brunt of that extensive heatwave through the course of tomorrow. for us, it will be a fresh

appeal to the day, a mix of sunshine and showers, most of the showers in the north—west, initially for northern ireland and western scotland. a few of them getting into parts of northern england and north wales by the afternoon. the southern half of england and wales should stay dry through the day, with temperatures up to 25 celsius in the warmest spots, most of us getting high teens or low 20s on a sunday, still above average for the time of year. as we look ahead, sunday night into monday, we have got high—pressure out toward the south—west, low pressure sitting towards the east, that combination means a little more of a north—westerly influence to our weather into the new working week. so it's still a largely dry, a bit of sunshine here and there for monday and tuesday, those temperatures return to something more typical for the time of year. bye— bye.

this is bbc news. the headlines at one: president trump wraps up the g20 summit in osaka with news that us companies will be able to sell goods to the chinese tech giant huawei. we are talking about equipment where there is no great national emergency problem. us companies can sell their equipment. at her last g20 summit as prime minister, theresa may says she hopes her successor is able to secure a good brexit deal. i believe they want us to deliver not just what that means in terms of leaving the eu, but the brighter future that we believe the uk can have outside of the european union. that's what i was working on, it is what my successor will work on.
