and just before we go, a reminder of our top story at this hour grace is facing, it's a long as heat wave on record has temperatures in the south approach. 45 degrees celsius. the countries national weather institute says the current heat wave will last around 16 days. veteran is a fax, our a documentary coming up next looks at active us trying to combat climate change, or news and analysis to on our website at w dot com. or you can check us out on social media apps piece of the universe. i'm sorry, richardson, thank you so much for joining the image of so many portion of loves us turn out in the world climate change. the story faces much less the way from just one week. how much was going to really get

we still have time to act. i'm going to like this, the mountains of always being a sole school and donny arnold and his friend derrick stream mountain is here on a quest for the ultimate swim. the best scaling. the pitts pending at healey falls 1000 meters above sea level. once lakes in the color, i knew him or in your axe and here the attention of cracking and hissing sound as it breaks into the ice blocks. it's just awesome to make a mistake. reading number of scientists saying this adventures like this might soon be some impossible. political roaming is nothing that can i see is

usually tall people, one big cliff teeth even years ago. you had 5 more days during the winter when you could really go climbing female. all cx over the course of a range of trips to africa, asia, and to europe. i've been else few years. we monitor the impact of climate change, torrential rain, and floods. devastating droughts on the home and a stretch of permafrost, so that hope is not enough. thanks to an unprecedented number of people working to come back to climate change from as such is around the planet to industry. lead is the global community of the united nations. these efforts are probably too late for particular regions on mountains, for example, have less no less ice and few iglesias the european alps as we know them now will

soon be many a memory the we live in critical times. if we do not respond to nature's warnings, we will find ourselves at the brink of the human maids. change the, the, i guess, the hyphen here, endorsement. of course we do here in germany as a major impact on greenhouse gas emissions and on the country. so we can see lots of impulsively on the palm loan and all of these activities mean deforestation, and extra emission somewhere else order as well. and so behavior mats are seen as

the ones are for height, and see it back to all stadium analogy and the model of calculating greenhouse gas reductions. we're now at the end of category number 2 devised by the time it takes stats. and if i decide to go, we find mass 9 seconds, category, emissions, where we already know how they would require further stay. which means following those that are already making progress though fast, don't worry about speeding up the expansion of renewables and stopping deforestation. and expanding electron mobility, implementing all of that would save us a further 12 giga tons of greenhouse gas emission. just one, a title is going to say those reductions from the 1st category and now joined by a variety of meshes together. adding up to 12 giga tons, almost half of the target using temperatures con, as seen in the alps, leads to water shortages even results at high altitudes now often rely on

artificial snow, which is extremely volta and energy intensive to create almost every village in the alps is dependent on tourism and therefore on snow and keeping winter sports enthusiasts high paid takes absolute priority. the show must go on while it still can, with half of the cost. increasing scarcity of voice originating from high altitude sources is a hub into a risk potential disaster vacation in pumps of the outs. notes for to is an especially short supply in this area. in the past, the water level in lake violation to be deliberately reduced. the precautionary measure was due to a risk of flooding from the vast amount of mount more today in the spring. we have seen distribution by just sort of us to be so much stone mountain. we have to make room for it and the lake wanted to put for a while. now there's being much less need to make the legs can absorb, it decides to balls. we don't need to reduce that water level. this you can think

of, you didn't see how he's supposed to bite off, and there are profound changes on the way across the out. here in australia, teams of specialists, their own constant duty to prevent mountain hillsides from sliding down prolonged periods of drought tend excessive heat, frequently result in devastating forest fires seen here in it's in these piedmont region, climate change sometimes a shortage of water sometimes falls too much the indonesian island of java being a prime example. the forests of mountainous regions help to store re more to the folding victim, to increasingly intensive loading, leaving rainwater to flow on handed into the valleys. sometimes the water sweeps away everything and it's tough to to choose from 20172018 the

the next. but it's estimate the by mid century climate change would have forced 14000000 people to flee that homes in indonesia were like thomas who can no longer till the fields. some dwellers whose tin roof tops have sunk into the sea and the residence of small communities like con, tie behind you. for them too, it's only a question of time until that'd be forced to flee from the rising bushes. around 1000 people were buried in the cemetery on the edge of the village called happy

beach. for some that will be no resting in a tunnel piece. the temperatures are rising everywhere, not least in urban areas. sites also to more air conditioning for homes and offices . and this is where experts from often technical university come in. one of the pilot projects is this kitchen studio. the energy saving technology is visible. once you literally look behind the facade, the entire building is enveloped in a fabric that keeps the sun's rays at bay. take just one step back, and it becomes practically invisible again from the inside. it's an experiment that has paid off the kitchen design to susanna, all of the scale, you know,

the cooling costs in the summer and lower greenhouse gas emissions. and the lessons is a good advice for you. um, what was the magnitude of this is an excellent example for the whole thing. it's on a very small scale because the motor, its amount of placing the focus, but still this text on facade surrounding the building can alone is safe around $1.00 tons of c o 2 per year in the buildings, climate control freak about if you much is the pro, while now it's not just being fashionable fabrics that has being was in by the machines of the universities institute of tech style technology. they also make sustainable products that can help to save the climate reset. some of the tech style facades is an interdisciplinary undertaking. here at this co working space in

a former church and on architect's work alongside civil environmental and climate, to engineers. and even some ologist and the results of the joint efforts a huge, the promising. i'm kind of a single item and actually put sending you a classical building will have a 90 percent proportion of placing a couldn't, which is already highly transparent that we can save up to 70 percent, including energy to convert to 60 or 65 percent of total energy consumption. yeah. and with an additional text office and a 4 because that's who takes the test out of it sounds like to more as well. and sometimes looks like it to this parking garage and benefit at the end of a to facades from often improves both the buildings climate footprints and it's a specific appeal we know already in the 3rd and final category of potential greenhouse gas reduction is proposed by the new climate institute in cologne. this involves particularly challenging meshes the to ready been implemented to dates

among the level of greenhouse gas emissions in the cooling of buildings as seen just now as well as reductions in industry and foaming. economist ought to my aid and whole fact co direct to us to post the institute for climate impact research accompanied by his colleague him on lots a comp. and on the right, the agricultural economist wants to see must have productions and the farming set to see production is responsible for a quarter of old greenhouse gas emissions in gemini, for example, people use an average of 1.2 chinos of meat a week government. i'm just now in become decimal, vital to people to see and often within for this need further reducing that figure to around a quarter of current meet consumption would have massive dividends on pool. 300 grams per week is a quarter of the current amount. so we'd still be eating meat maybe only once or twice a week, but it would go a long way toward reducing emissions. this was for those who own few good tom,

according to climate specialist nicholas who now the implementation of all 3 measures belonging to the final category could cuts an additional $3.00 giga tons. we'll add it together that would make around 20, giga tons. but some way show to the so she could get tons required. so game of it would seem, despite all those efforts more is not possible with conventional means. so what now if i invited who, if we carry on regardless and it by the end of the century, will reach a temperature increase of a little and a 3 degrees celsius. that would be a disastrous climate change. i don't, i'm not eligible situation in implementing the measures. no 3 categories. could nina, reduction of 20 giga tons by 2030, leading to a temperature rise of 1.8 degrees by the end of the century. well, if i would unfortunately not be quite enough to hit 1.5 degrees, i don't know, it's been a huge impact is a very important step forward. i imagine as ever speakers with here along the bed,

the maya, whoever, if uh there are signs of dispatch, every, with the newest, have kinda ruined, received 72 months of rain fully yet in august and september, during the rest of the people have to vote considerable distances to find who to dig deep. all the people who live here say was a used to flo. abundantly through the mail, beula and into the little go no river before discharging into lake chad. but those days ago and due to continually decreasing rain for the comfort room, this suffering from devastating droughts as these neighboring chad, the lakes, atlanta, its name to the last, the country, is the sole natural source of for 2 in the region. michelle remotely arrived from the u. n's migration organization to spend is touring, the saw hel, region the

in the spouse shade of a friend, child looking tree. he speaks with mohammed abraham. he's a honda and tell us a visit to about the terrible o d o. his family suffered before finally arriving at lake chad. yeah. that and i show him the actual climate change has a huge impact on us. here it is. if there's no rain, no plants grow and without green plants to eat, our animals die. so herders like mere hit very hard by the want. ok, so i up from the chart, the chop sides, nigeria inside the country, not inside any websites. the only dependent on this. so you can utilize that.

dyslexia is unique, is just a fresh, what are we seeing? i'm not a good area so. so many live your dependent on this. let me try and if they like, charge us it to be a serious environmental cost or fee because we don't, they like charge. we can hardly talk about living at most of the intellect, tried to reach on to get the group sets out to inspect the livestock, which are right now being high, did a few kilometers away by mohammed abraham sun along the way. the small caravan of cause passes through one of the countless strongly dumped depressions and the land numbering in the 10s of thousands. they used to be a positive lake chance, but within the space of just a few years,

the lake has shrunk, cutting almost unfathomable right. in 1963 lake chad covered in area of of 25000 square. economics has by 2007. it was just 2500 square kilometer is more than 90 percent smaller. a trend that set to continue the millions of people in central africa have already left the increasingly average region and headed sounds. well, some try to go said the newest to europe. almost 40000000 people still live on the sinking shores of the lake. if lake chant was a completely dry up more than $50000000.00 people would probably become climate refugees, mohammed people, him and his extended family already come on to the category of environmental migrants.

it was the cook. i had a lot of animals $60.00 to $70.00, but there's no water anywhere and nothing grows anymore. all of the cam most except for 5 have died. we were 1st in the share then in nigeria, and now we're in chat. one is, it's been no better here either, and we'll soon have to move on to wherever they're stillwater in the south. i need you to, i didn't, you know, the late charge remains the source of nice the millions of people. but as it continues to shrink water was becoming and of a sketch and move, i nibbled results. and so i rode the land and the fish in the lake as a can't get smaller competition for these resources will become increasingly bitter . even now fishermen in the region face dwindling stokes of comp nile patch until

up here. but there are projects that give reason for hope such as here in neighboring saddam we were present when a local fed trade organization was paid to visit by its funding department at cozier. a green online search engine based in berlin. replanting officer katerina should be mine is a sign of the sustainable approach taken by my time back comp. for years, his small and g o has been helping women in sit down to grow a cation. the numbers are checked regularly. how many seedlings have been counted? and how many have survived the full 100000 seedlings were planted in 2021. a number scheduled to almost double in 202290 percent of the trees of whether the conditions a minor miracle. the women often have to carry the water from very far away. at temperatures in excess of 40 degrees celsius. off of the precious commodity is for

the families. the other half of the trees in the projects involves full 100 women and has the, the pump strength every several. doesn't need to deep to reach the ground floor to the survival specialists in a very hostile environment. and they also provide an actual product that yields a decent profet i have some boma education, technical for i. it has the big advantage of starting to produce income after a short number of years. it's called a team and there's some arrows i mean, so each treat them with 4 or 5 year olds, which can increase over time as the transportation form and the so it's a tree that generates a continuous and kind coming in on the launch pump system. a bone dry,

awesome with little oh no vegetation insights the but suddenly that changes dramatically as we reach the village of shad gra, home to some 20 sounds indications. a veritable forest of trees constituted by nadia abraham mohammed was seemingly inexhaustible energy and the help of other local women. she shows us how to make cops and the bulk of the trees so that they release the sap that hawkins into the valuable will. material, gum arabic is used in a wide variety of food products including coca cola, mat let's the fees. um, you should get a heads up. why? because some of the the a cases give us the gum, which means the regular income be the 2 seconds they stabilize to swim that the way they prevent the desolate spreading. oh female. they protect all the vegetation in all regions and fish, because the cases are so strong, intensifies here,

but they provide shape to for one single seasoning in itself doesn't mean much, but in the millions of budding trees, main hope to done. and should the scale increase to the billions, they could even help to alleviate our climate problem. nadia, even a mohammed and other local women from the village of shedra know the importance of the trees for the saw how region. most of the children are now able to go to school, thanks to the profits from the prize to come. and with a little luck, they'll go on to enjoy further education or training and find a job. seems spend 3 years traveling the wild,

investigating climate change. our immediate focus was on the appalling consequences of unabated global warming, the increasing frequency of minor and major catastrophes, the growing threats to people on the ground and the associated rise and people seeing that homelands. we also talk to those who are actively combating climate change and refuse to see it as a lost cause. among them is kristy and call the founder of the cozier. some would call him an idealist. he turned to successful company into a non profit operation. since then, instead of going to invest as any excess income is channeled towards new trees. for every 50 search queries on its website. because the has committed to prompting a new ceiling in one of the 35 country, primarily around the a quite to ebay. now, number of a $175000000.00 guys with guns by $1000.00, which is

a fun part of the onboarding. it'd be great for us as a team to have planted a few 1000000000 trees by twin to, to teens. that's the really important thing is to come to the big green thinking society and there cuz there's, i've to no longer pump out c o 2 into the yeah. but also getting some serious thoughts. i need of to how we can repair what we've destroyed over the past few decades use motivates, here's a couple of combust how many notes notes in the sometimes even if any occasion in a you might say climate change in the surrounding debates with many a transit tree spec to take january 2018 when it seems that when so was finally back to how it used to be on lacey as 3000 in switzerland. the fabulous conditions for skiing and tube opening. perfect key chris snow and happy ski lift operators and vacationing families from around the well

the h. d. in spring 2018. the mood was positively u for rank also among scientists. a team lead by lacy rex. but to mathias whose from the switch to federal institute of technology in zurich, visits the mountains twice a year. once in spring, i think i know since when the next season begins, the they investigate how much fresh snow falls i have worked in winter. and the sickness of the snow comes over the ice. the most snow, this being the best to the condition of the place. yes. on this day, the 25th of april 2018. it was in better shape than it had been for quite a while. the of the move in 5

meters of 6, no fell in winter. me? do you want me to hit tough? it's a saving glitch on the nose lights may. so when these a sneak of us like you only measured this non water equivalent one who has substituted 7 places across switzerland. and i think it showed that in 2018 the smoke couple was well above offer. and just by assessment wasn't quite as deep everywhere in switzerland you'll stay was here. housing. but it does look like that was perhaps as much as 50 percent more than in a normal year meal alternate in pneumonia. macias hosts would be back in the fold as would we the on the more kind of full sense of climate change. fatalism is no better than naive but blind ignorance savers such as visionaries and all those ceasing counts of the books. some ideas might seem to be on the fantastic hillside pies in the sky and sometimes

loud ones that dance this kite launched above the danish gem and buddha is punch of an attempt by humbug based going sales to harness wins power where it's available in almost unlimited quantities far above the grounds, the kite strikes the re pop into the a to a height of around 700 meters in process hollering, an electricity generates at the end of the cycle, the power line to is pulled back down to the ground with a minimal energy outlay and the game of yo yo, begins the fresh maureen power from the winds in abundance. the fox may i altitude way and gives us more energy and a steadiness supply than we near the ground and are at the height of a normal wind farm. the sun, i'm no mind and i don't know mind uncomfortable unless we start on instead of being

slowed down by trees, buildings, or mountains, we can move free man bag and that kind of which kind of thing. but then that's why we have a far greater physical potential to harbor college has put inside of us double wind speed and 8 times the energy yields. the kind to operate is what with smaller devices like this to replace climate damaging diesel generators. but there are times where much logic heights producing of a one megawatts of power the on these i can, the system is on the reasons particularly suitable for being used at as the off shore. in larger wind farms as a large scale power plant as tests throughout its close customer on these a lot of these high can be mounted on a small floating pontoons on without the need for expensive foundation in the open from them into the the kind spilt by sky sales are in,

in swooning way to produce small, green palate in the long time as one component of germany's energy transition in this crucial decades. that one of many ideas bordering on science fiction from geo engineering technical intervention on a planet tree scale, the cirrus clouds at high altitude are akin to a done with hate to trumped underneath. if you destroyed them with chemicals, the heat can escape from the atmosphere into space. or conversely, you produce small accounts, but at low altitudes, via turbines, on thousands of ships with the fleecy cloud serving a shade providers. from here things really assume gigantic as i mentioned, space shuttles this to beat sofa dioxide in the stratosphere like

a big volcanic eruption. the dust will then cool this, instead of sofa of the climate fix is trying to use trillions of minute to shields to block the sun together forming a giant stationary power as solid sky vote. and g o engineering on an unprecedented scale is an incredibly costly and risky concept. critique say that manipulating the clouds, for example, could throw the world's climate completely into disarray. but to his time being of the essence, every option deserves to be considered. one idea is to remove the home for greenhouse gas c o 2 from the atmosphere as is being attempted by switzerland based climax. failing to meet emissions goes despite progress leaves us limited options says the team. but as of yet me to ease us younger and sense on the home phone, so you know, around 2015 will have to actively remove around 10. you get tons of c o 2 from the

atmosphere every yes on this and we don't have many options. there are biological options like reforestation, and all the possibility of deploying machines, which would increase c o 2 removal by a 1000 fold. and so as high as i don't, i think the time works. pilot venture was installed on the grounds of a waste to energy power plant. that's because the filtering greenhouse gases from the via these enormous collect has, requires a lot of energy on to the concept to make sense that the energy has to be renewable c o 2 molecules of filter dash of the and then it quit find uses of the 900 tons produced annually like the nearby industrial green house. i'm in the a drop in the ocean climb looks who's thinking in completely different dimensions. several 1000000 tons per year. which is why the company has signed and co operative deals with the energy experts in no way. for example,

this is this like mount royal and gas turning platform for a quarter of a century. it's norwegian operators have been experimenting here with the injection of c o 2 into the ground, deep below the sea bed. and now the venturing into a new dimension, special ships will soon be cooling at the major ports of northern europe to pick up liquefied c. o 2 mainly from polluting industries such as steel and cement production from the the material will be transported to the coastal town. if you got this will be the terminal for new ways, new c o 2 receiving facility. critics say it would be better to prevent emissions in the 1st place, instead of capturing them off the woods and as the argument that the greenhouse gas could damage the sensitive underwater ecosystems. in new way itself, there are

a few opponents, the countries parliament to prove the idea with a large majority. while the government is not quite as the strong back cover of the polar light projects, the comp and capture and storage or c. c. s is probably the most feasible concept currently emerging from the worlds of g o. engineering. according to current estimates, the norwegian continental shelf can observe a t goes homes of c o 2, the same amount as your ups entire greenhouse gas emissions the next 100 years. the 1st chips, the set to don't care as early as january 2024. so right now we're at the northern lights, receiving terminals. this is where we will receive c o 2 from all over europe. this is the justice where we will take the c o 2,

the ships will adults we will take one and a half 1000000 tons of c o 2 per year and stores here temporarily before it comes off shore and injected in a deep the rest of our steps the, the noise from the i got the liquid c o 2 will be pumped through a 100 kilometer long pipeline and then injected into a pool rest today of sandstone. 2600 meters under the sea bed. a 75 meters thick layer of shale prevents leakage in origin. despite sort of these efforts, it's unlikely that they will succeed in lowering all greenhouse gas production to a tolerable level by 2030. so an additional plan is to actively remove c o 2 from the atmosphere and essential step also in the eyes of the un inside governmental panel on climate change. the risks appear to be manageable on how to

buy. uh, we have experience from uh, the sub surface in the north sea, having done oil and gas explorations there for more than 50 years. now we take that to experience all the knowledge that has been developed on the geology and apply that now to c o 2 storage. we have experts in the field who have evaluated this up surface to say that because of the primary and the secondary seal that we have in place because of the geological structures they success, which is even if capturing and storing greenhouse gases with to one. however, it's not a silver bullet solution. any realistic coke depends on further research and further reductions, everywhere is the one and a half degrees target still feasible. a tom finish really disillusioned this and

he managed to decrease from it, but we can consider. so it's fortunate because we can't give in, we are not allowed to give in. we have to divide this. i do the best that we can for the, for the future on fall change in time. the next 5 or 6 years will be decisive, spoke of okay, we will really have to pick up the sy, starsky, unless you're missing diets. we absolutely have to keep on going. and also when the indications of an impending sheet age can be found everywhere. as all individuals determined to take action, however unconventional in russia's far east climate champion nicki to the most, has fence still around 20 square. columbus says that the large tracts of land he's bought. this is where he plans to realize his vision of a bank to cold, the wealth projective ma'am us proportions seem of wants to use a professor of animals to create an ecosystem corresponding to that last scene in

the pre historic place to seen era he already has a 100 animals great, and even a small head if he acts. if everything goes to plan that will eventually be $5000.00 on an invoice here. the time it to colleges to wants to prompt a natural muffle in the winter. and she's animals have already begun. as they trampled down the mountains of snow, the cold can penetrate the soil unheeded. the the, the scientist shows us how his place to seeing park has its cold, is working deep underground. over the course of several weeks, he calls down to private permafrost tunnel system that serves as one long

scientific club or a tree. high quality senses and countless soil sample evaluations show above all one thing how vitally tools to compress the masses of snow. above, with the help of his 4 legged associates, its horses buys and yet the seats, the horses yaks, bison reindeer that dig through the snow in the winter because they have to reach their food. and when they travelled down the snow, instead of one meter of snow, we have 10 to 15 centimeters of really dense snow. instead of a thick winter jacket, you just have a thin please think winter jackets, you're good, like a tiny, tiny, please. so sensors changes, i'm sensors show that in places where there were no animals. the ground temperature in march dropped to minus 10 degrees at a depth of half a meter. but in the park where our animals trampled the snow, the temperature dropped down to minus 24 degrees. so this is a huge 14 degrees difference. i felt saint cloud different

the on the door. definitely. so this will definitely help humanity use wavering between a horrible future scenario and an extremely horrible future. so we have to fight and listen. it's not a question of defeating climate change or global warming. so the point is simply, to what extent we are unable to save human existence against the visionary who came out of the cold and wants to return to it. the key to the most may never succeed in his mission to save the world with huge heads of animals. but

what he has already achieved is a growing number of people realizing the devastating effects of fed up and for us to mount and the resulting release of more greenhouse gases. the trip to the republic of sako then takes us to the capital get quotes, which is this group of for such as from prague, is being hosted by the institute of applied to college g s. the no. it's like just returned from a crate to carved into the permafrost, where they discovered bones belonging to extinct prehistoric animals. the site to the 1st, an ice remains were found, was named the battery guy, cook crates, but locals call it the gateway to the under. well, it's easy to see why the

in the 1960 is a small section of forest was cleared to make way for a new road. the time of for us to reaching any bernice, the trees began eroding a test. the resulting hole was just a few meters deep. the sea that missed, i mean, limits of, on average the mega creator is between 40 and 60 meters. looks and in some places it's 100 meters. it's 1.5 kilometers long in about one kilometer wide right now. but it's hard to determine exactly how wide it is, because it's expanding so quickly to use these kinds of catastrophic events could become increasingly common and not just in residential areas, but anywhere in the wilds forever the oil pipelines and natural gas facilities in our entire infrastructure could be attracted to the physical world in september

2018 place cx, but mathias, who sent his team, paid another visit to switzerland. school a c, a 3008 pro. heaping highly encouraged by the enormous amounts of snow and now the sky. and if the sweat from climate change, if we invest anything less than maximum effort, is already a parents, here, iglesia, the crossing is going all the snow that should be covering it is going in the space of just one. some of the it wasn't gonna play to see about, i'm talking it is well the here in a phone that was just an incredible small government fund. if we just please me, the smell was compassed and compressed. think about it. 5 meters, every single, forced in 3000 meters of sea level outgoing mail. today, of course of a,

the you're watching due to the news coming to live from berlin, greece sizzles as it faces it's longest heat wave on record. extreme temperatures have prompted the closures of tourist attractions, like a proper list. and sparks wildfires and evacuations in several areas. also coming up on the show.
