permafrost is flowing with dramatic consequences for people and animals and higher waters. the egyptian coastal city of alexandria is fighting rising sea levels and its own demise. our planet consists largely of water around 70 percent of the earth's surface is covered by it. climate change is causing temperatures to rise until now oceans have absorbed a large share of the heat. helping to keep temperatures in check bouts has temperatures rise. so does the sea level. the entire planet is feeling the impact of melting lacey us. since 1900 sea levels have risen by around 20 centimeters and particularly sharp p since 1993. if this continues sea levels could be 1.10 meters higher by the end of this century than they are to day. worst case scenarios predict to rise of up to 1.7 meters in alexandria in egypt. the rising levels are already causing great concern most of the beach has already been swallowed by the sea. just a few years ago, sunbathe is lounged here on 6 rows of chairs. only one remains. almost 30 meters of beach are now under water. often the waves lapped directly against the buildings. like at this popular beach cafe, the view is unique, but the future is uncertain. tom, he made as income is crumbling. the 42 year old has been running his cafe for more than 20 years. but now it's days like this entire row of houses seemed numbered. lowe's to moraga. if this continues soon, there won't be a beach here. we show nothing at all. oh, certainly next year the sea water will come right up to the edge here. we will see cracks on the wall, testify to the danger, tommy. he made a has lived in fear ever since 2019, when the porch collapsed under the force of the waves. so do. i was bewildered, bewildered. i thought we were experiencing astronomy the former pull of the mediterranean is now threatened with ruin, founded more than 2400 years ago by alexander the great alexandria was once a major centre of civilization. to day it is egypt, 2nd largest city, with more than 5000000 inhabitants. and over 60 kilometers of shoreline, the voice creeps ever closer to the historic buildings. as the sea level rises, scientists fear that sooner or later they will be completely submerged. and if you, how well in loss of about half a 1000000 heckler's around alexandria and the nile delta, you will senior, the around 4000000 people will be affected in the summer. if possible rises by one and a half meters around 8000000 people in the delta and then we'll be in mortal danger unless i'm a fisherman delta water in lea at hotter the city council is desperately trying to hold back the waves. coastal protection workers are sinking tetra pods. wayne tens of thousands of tons along the coast. the project has been underway since september . the clock is ticking. palaces, historical bridges and lighthouses must be protected before it's too late. warns assa aysa the head of coastal conservation in alexandria, advanced scenario no more. in the worst case scenario, the historic defensive wall will collapse, part of it already broken away, but we repaired that idea of what if the wall collapse is completely the park of sinking to the c. $1000.00 beaches will also be protected with a wall of concrete blocks, cranes are gradually sinking the tetra pods into the sea, costing tens of millions of euros. it's a dangerous mission against the forces of nature. has i'm on by her yet that we've often had to stop our work and start all over again because of storms urges enough then in another place, all our equipment was submerged by water. that to the middle were these are already enormous challenges because we're working with c and severe weather conditions, especially in winter. in the cities narrow alley ways, residents are at the mercy of the she had volumes of water, the small apartment of ultimate ramadan and his wife, missouri was flooded 4 times last winter. as the result of rising sea levels and heavy rain, the pensioners don't have enough money to keep re painting the walls or even to move away. they make do with plastic top hollands and stones on to which they place they of our nature. mark them on that were really worried. of course our lives are in god hands to tell them what should we do? a letter in the last flood. they lost their furniture and most of their electrical appliances around for days they couldn't enter their apartment and was stuck out in the street. here was elena and alex, i'm scared will lose everything with alexandria. sewage system has long been unable to withstand the mix of rain and sea water. not enough pipes that are too thin and often clogged even though the city council regularly cleans them. new pipes are being built near the coast to re direct the water back into the sea. but all this is unlikely to solve the problem in the long term. thought i'd already, i'm affected by the to of course, as an employee, i sometimes feel i haven't done my job properly, but i do what i can. well, we work hard on what's happening here is beyond our capabilities. and yet many people in alexandria are hoping for a miracle, and that they'll somehow get off lightly for tom or he maida and his family. their very existence is at stake. morgan, her shot, do garza, i wish the coast would be like it used to be. am again, which we hardly have any beak here any more than almost nothing of the global minimum loma. i hope the government will implement its rescue plan quickly give more and more. i'm begging them to save the coast and west cafe will amo is to wish likely to go unfulfilled. the people of alexandria can't stop climate change with wishful thinking. now another place experiencing the effects of climate change 1st hand is alaska. it's getting warmer and warmer in the u. essays, nor than most state. last winter temperatures climbed to a record 19.4 degrees celsius. to put that in perspective, minus 20 degrees celsius is considered normal at this time of year. such changes a wreaking havoc with the lives of people and animals who live there ah landing, it would geography. the change is impossible to overlook. the permafrost is melting . the once frozen landscape is now littered with pools of water, reaching right up to the houses. residents in the united states northernmost town find the ground is literally melting beneath them. just a few kilometers away. scientists at a u. s. government observatory are busy tracking climate change. brian thomas has been in charge here for 15 years. for 50 years, the station has recorded c o 2 levels and the atmosphere, and track the temperatures and precipitation levels. we noticed over the 40 years old enough plus in a little bit more almost 50 years now. we noticed that big change almost a 100 parts per 1000000 change. now, the last time there was this much change. it was a 5000 year period after the last ice age when the war froze, warming. so what we've done in 50 years, humans have caused the same amount as what was naturally happening in 5000 years. new equipment has just been installed, designed to analyze the air even more precisely. it's an exact gauge of global warming. the scientists identify how much carbon dioxide is stored in the air or we bring it in from our really tall tower, outside, frieden, on these on, on the hoses, present to this instrument. and inside this instrument, we put a heat laser in there, just like the heat that's coming off the surface of the earth that's being trapped by the carbon dioxide. we recently, we create the conditions that are outside. we do that in the lab where we can measure and then we know how much carbon dioxide is in that sample. look chaotic, his want to for climate change observatories in the u. s. they're run by the national oceanic and atmospheric administration. it's the known sort and they're all located far away from cities as an industry on the bridge. we have alaska, we have hawaii. we have some of our, we have soft pull. we have this nice connection across the earth. when the when moves past and what we're looking for is we don't want to look at what's happening locally the point sources of pollution. we want to look at what's happening in the well mixed air that travelled around a lot. climate change is happening on the observatories doorstep. the snow is melting earlier in the year, and the summers are getting longer. the blocks of ice that once served as a natural protection against the waves and rising sea levels have gone. in recent decades, the air temperature in the arctic has risen twice as fast as the global average people here in new york vick have witnessed the change 1st hand the ocean used to freeze in october and now it's not freezing. sometimes until late january said the storm surges normally the northern winds in winter would be coming off of the ice. and now they're pushing the ocean waves up against the coast. so you're seeing a lot more erosion occurring because the ocean isn't freezing. you're seeing damages to the critical infrastructure in the community as the permafrost is dying . buildings are sinking, and they're, they're being cracked and damaged. how i remembered in the past like 20 years ago, their legs know and stars knowing before school because school would start like the 2nd week of august and, and like that kids would start walking to school in nash no. but now did a read the rising temperatures also pose a challenge to local hunters. the wild animals have started to behave differently. it's a real problem, says billy adams. he's one of the best known hunters and who catholic. his indigenous name is o'clock. we learn to exist with was that we depend and sharing the, the health of their population. the timing of the migration has changed a lot more for lease up to 3 to 4 weeks earlier than we have to change with that. also, for example, in the eighty's or ninety's, we could go a few 100 yards to gather some of the animals from mature. and now it could be 15 miles 20 miles further. but the risks have not only grown for the hunters. residents are also in danger. in winter, a growing number of polar bears are entering with their natural habitat melting. they come to places like this, searching for food and they bite to survive obnoxious services. as a polar bear ranger are required, we had over 90 years, come assure and they were within our community and into our communities. we had to make sure that they were safe and make way. we started pull a beer to turn the program and we made sure that the people were saved. the children were fav. lucky. know it's been hurt yet so same things happening in canada and they've not been quite as lucky. they've had some fatalities with barriers in town where they shouldn't be. it happens in kind of waves. it's sort of depends on sort of everything comes down to the sea ice. the entire ecosystem depends on the ice. so even just a small rise and temperature has a huge impact on nature and on the lives of the people who live here. and yvonne duke is a biologist. he's lived and worked in calgary for the past 7 years. be a great. the scale of change is huge and it's not getting better, it's just, it's slowly getting worse and less, less dependable. just like to say for my job, i can't do my job as easily as i used to because of the ice for a lack of ice on the famous, true for the wildlife, as well. back to the observatory the center received a rare visit from washington. the summer scientists, the representatives of numerous political institutions, attended an official open ceremony for a new state of the art research facility. we can see that if we don't do anything, right, i mean, we're going to continue to go up, right. so this represents warming that's already baked in, right? this warming is already going to happen because this is already in the atmosphere. so anything that we can do to change this right now picking it down, we would have to actively remove. right? but you know, the more we can bend it down by not putting as much in the atmosphere to better off . we will be experts often describe the arctic at the epicenter of climate change. in places like yuck. that change is dramatic. and it seems that no turning back mm plastic bottles, a practical and available everywhere every minute. 1000000 of them a sold worldwide. the number of bottles produced in a year would be enough to cover the distance from earth to the planet. mercury. emptied and thrown away, very few bottles of recycled most end up in the trash or in nature. which is a huge problem because plastic takes about 450 years to decompose. the world desperately needs ideas for how to deal with old plastic. we take a look at one in rio de janeiro, ah, how can skateboards help re as largest havana to reduce plastic waste? this question drives canadian, ari and roy agony, who is realizing his vision of sustainability here in the midst of thousands of bottle caps in his improvised open air workshop. the 28 year old has declared war on garbage, at least as far as the lids are concerned. i he said he might visit today, i've already gathered 400 kilos of caps and i haven't managed to recycle all of them yet. he has got all this, but things are progressing mileage. so michelle processed the process begins with one of his help is cleaning the lives of this of silkwood. yeah, a right now for villa ra senior, the lids used to be just throwing away. now these almost to kind of recycling fever that's broken out since arian showed us that you can make skate bullets out of them . on a, on by a ghani and mechanical engineer drew the plans up himself at the heart of it. it's this little mold in which 500 lids are melted into escape bought deck, using this pizza oven. didn't put a lot the case if that change those gate lords or an ideal product in my view or us because they're relatively durable, making good and i can recycle quite a lot of bottle caps in one go might voluminous blashley. a mac, was it the 1st time i saw a plastic skate board on the street? make one 0, i thought gauge mer, who is your faith and you blush. i can produce that and sustainably bluff. i said you blush with his club. every day he loads another tray of bottle caps to be melted at $180.00 degrees celsius. 80 years ago, at a young i agony traveled to brazil and fell in love with this area. the mounds of garbage generated by the veil as 100000 inhabitants inspired him to come up with his sustainability project. now a small army helps him collect the caps, the treasury, cyclists of ro cigna. one of them is muddy daughters audio from connecting plastic bottles, cans and glass. she has the equivalent of $650.00 euros a month. she puts the lids to one side for audi. andre agassi only so that yeah you for us waste is valuable act and brings and money is all been thinking about money . my son and i collect things for the recycling center, but the bottle camps. uh huh. we usually take them highly, be handled, but i've gotten many of her neighbors also dropped the bottle caps off with her with inside the keyboard they had thought we know the lids will be given a new life, so we get them on the rear. right, well we've got a local recycling economy here with class dale, the social worker, marcella played royce, also works with audi on the diagonal. he leads the recycling network in which maria does audio participate voice. thank you, maria. this is great and we can make some more skateboard, sagebrook with muddy added as audio lives with her 5 children in a small apartment in low cigna bedroom pros. yet like in the hospital there was a garbage recycling campaign here. melisha that that's why i started working at the dom by the might. that was 3 years ago. it was today's own mom must said okay, roy help to get started. this which what was the issue? we showed maria how she can earn money by separating waste bottles such valesh. i'd have to perform a total of 8 families. now make a living from waste, recycling at our 24 rubbish, thomas and raw senior. i'm. i do want bravo. he would be us like maria, they bring it all to the recycling center twice a week. my fidel bullshit. bother the bi, catch the bottle tops, end up in id, on gigantic skateboard. mold. the mold is dunkin water, to cool it down. my dog affiliation with i'm really happy that we develop the sustainable product. i give it that should also be fun for people to use. says i saw foolish man. the skateboard is trimmed with a sharp knife on an like on a re uses the excess plastic later. he still can't make a living for making skateboards. it's only recently that he's been selling his booth online for 90 euros each which includes requests for personalized designs. the entrepreneurs, he is part of the proceeds to finance a social project, food parcels for needy families delivering sugar. pastor flower and rice probably been lose me. when my baby was born, i lost my job. even more marathon for now. i'm unemployed. has them in my husband works, but his salary only just pays the rent that they that porker father of our gallagher coming home. i haven't eat meat for ages. i can only afford rice beans and ankles face to face the 2 men already have they side set on their next gulf. the arrival of a 2nd hand robot that will take plastic recycling to a new level. adiana agony paid for it with his savings. he's convinced that the project will soon pay off. i guess i missed the lawn technology in law of a whole. now i want to apply robotics and new technologies to engineering architecture and recycling it to create sustainable products that are popular product dish gates won't kid. i think it will work awesome with the yeah, the 1st tests for plastic tables and chairs are promising. this 3 d printer should soon be processing 6 killers of plastic per hour. good news for a senior, the fabiola where more and more people are helping to transform plastic waste into useful objects that are both colorful and fun. cities littered with plastic clogged rivers, dead animals. according to india's environment ministry, the country produces $3500000.00 tons of plastic waste a year. but experts believe it's actually much more. now the country has banned single use plastic. however, implementing the band is proving to be a big challenge. for student ashish, tomorrow's role models or the thieves from the t. v series. money heist. but he has a more sustainable goal in mind than holding up banks. he aims to make his home city of delhi plastic, free through what he calls, plastic height blotting over. we steal plastic from people, some just give it to us, but others get angry and refuse so that we often hear the companies need to stop producing plastic will only their level. so it's not use it any more at all rhythm, hard to really blustering when he india without plastic until now, hardly imaginable. but at the start of july, the government introduced to strict ban on single use plastic. anyone who continues to sell it thinks of she find vendor prakash. john gupta has already been targeted by the plastic ice robbers sometimes the death. yeah. the government is putting us under pressure of not the companies that produce the plastic in the end. it's the poor people who are being pressured and find we're being told to reduce waste and not lose any more place like what we would do that. but as long as plastic is being produced, we'll use it. a lot of time is up because then i have a plumb labor cutlery, and plates made from wood or cardboard are more costly. so they're not a viable alternative for many bumping activists. don't take that into account. they simply drown out any protest. look how much plastic this man has. let's get it. their leader since the tone. he's calm, the professor like the mastermind in the t. v series. one was i'm gonna go to beg. people need to understand that the government alone account change thing will the i, when the demand for plastic falls, they'll be less on offer until we all work together. nothing will change as madame name got to get up with resumes veiled along with their plastic ice. the activist also organized theater performances to illustrate just how big a problem, plastic pollution is, and to give passers by ponds for thought. i remember the was but sometimes you think about picking up the trash lying around, but then you just leave it there may go to them. but when others take the initiative that's quite encouraging to do so. hm. how may i please of the government? medically it makes it easier to do your part. you either got them up. the plastic robber st. most people don't realize just how destructive plastic is, but a sheesh kumar hasn't given up hope of making a real difference. especially now the group has had some success law sticky or that are many activities make a powerful impression big or people talk about what they've seen at home with their family and friends about them naturally. something like that has a factor. ah, the group plans to conduct more plastic high surround delhi in the coming months, even in the face of great resistance, they planned to keep raising a ruckus until india's capital is plastic free. ah, and and that, so from us at global 3000 this week, thanks for watching.
