rising water temperatures are becoming an existential threat for the entire echo system. close up. next on d w. if you ever have to cover up a murder, the best way is to make it look like an accident. raring to me. you've never read a book like this. why don't you literature list under germany last reads. mm. ah ah, the arctic home to a giant ocean credits of the oca or killer whale off the coast of no way. we join an expedition under extreme conditions, the water,

his eyes cold, the air temperature below freezing. marine biologist lucas mila, is getting ready to observe. a pot of oak is up close. there world is on the threads from climate change. lucas, mila isn't the only expert concerned about dramatic consequences for the oceans, and their inhabitants were heading out to sea. lucas mila wants to know how climate change is affecting the arctic ocean. so he's looking for a school of herring. as temperatures rise, herring are expected to keep moving further. north. cold water is where they feed and it just so happens that herring attract oak is as their easy prey

live, forbidden, broadening the fuel and see are a deep and wide. so finding the oak is takes a bit of luck every day they could be somewhere else or wherever they are a herring. there are orchestra. it's lucas miller's 1st time here off the norwegian island of shelia, inside the arctic circle. he has no illusions about how serious the situation is here. meineke wished his august us. my greatest concern is that we're inflicting irreversible damage on the ocean is an ecosystem for d. v. domitian. time to rescue nature will never be as good as it is today. is august the sun before, if we destroy natural habitats to day, it will take hundreds or thousands of years to recover them after towers law. and in most cases, we don't have the motivation. that's the ability my,

all the knowledge to bring those habitats back to fish. we don't even understand how they work today. not profiting, busy hot of it's day one of the expedition. he and his team have been out since early morning, but so far they've not seen any herring. thank you. of time is of the essence. it's late november and there are only 3 to 4 hours of light a day of commit to this. took the very out of it. sure. the team also includes underwater camer, man, leonard, a horse and felt that is the front line. you have the blank and white contrast of the fuel, the waves coming up, the wind whips up the waves and sometimes it looks like there are whales coming up and breathing, but it's not bad. it's just wishful thinking. my darkness is closing in. it's early afternoon and there freezing as they returned to the harbor

was noise of circa. we covered about 100 kilometers to day. that's quite a distance kanaka. we didn't find any orchestra, and to morrow we'll try another fjord and hope that mother nature blesses us with a sighting of dignity, so we can get them on camera. for the lindsey top. it's not just here in the arctic that the ocean is changing. water temperatures are rising world wide because the oceans absorb a lot of the warmth created by greenhouse gases in the atmosphere. surveys down to a depth of 2000 meters showed that very clearly. since the 1980s, ocean surface temperatures around the world have been rising steadily in 2019, the temperature was 0.77 degrees celsius, above the average for the previous century, many small sea creatures are unable to survive in the warm water.

other fish species have begun migrating towards the poles in search of cooler conditions. those who can't cover such huge distances will presumably die out. and that will have consequences for humans to females. ziemen up from fish for more than 750000000 people worldwide, fish is an essential source of protein on a diesel. without that fish, many people will no longer be getting enough protein to survive in or whatever. ah, and there's another problem. the oceans take in huge amounts of c, o. 2, that's helped slow down climate change. but the moraine ecosystem con, continue like this indefinitely. as christopher simon from germany's institute of baltic sea fisheries knows all too well, actually about who had to feel the impact of climate change would already be far

more severe and far more visible if the oceans hadn't acted as a buffer. but at some stage that buffer capacity will be exhausted, and they will then needs centuries to recover it. he says profound changes are already visible along germany's coasts. in dallas, see this year we've proven for the 1st time that the productivity for one of our key caring stocks has dropped significantly, which will be reflected in the harvest in the coming years. i'm shocked as a productivity for this stock is half what it was 30 years ago because of climate change and so forth. and that will directly impact our coastal fisher research or mit adolfo for lucas miller. it's day 2 in the arctic. the biologist is once again off to look for hearing

about a bond, but but 1st he applies a naked flame to the protective coating of his new goggles. to prevent them from fogging up. next he prepares it belt with lead weights. he wants an extra 13 kilos to help him dive to a depth of 20 meters. we got thin, white jacket, b. all right. thanks. episode figure. we were ready to go with a lift. good. good. good. his brother said soon they get their 1st indication that hearing our round birds circling above the water and just a few seconds later the oak is arrived. this sense of anticipation is huge. even for these 2 experienced divers, neither have ever been in the water with these giant creditors.

lucas miller dives without an oxygen cylinder that allows him to move more quickly and get closer to the oak is without disturbing them. hold i let's all that. i took my last breath and dived. huh. it's like another world you're waiting in. the bit is huge shadows to approach that of does then the entire post winds passed out to sula f like itself. mm. bulk is used nachos sienna, known as echo location, to communicate with each other and navigate their surroundings. the group functions as a unit with the bulls swimming on the outside to protect the pod. very thumbs spider. i mom, it didn't yoga once, i'd been down with the oak as 2 or 3 times and the bulls understood that i posed no

threat. an inquisitive mother came right up close to me with her coffee. i am young to fo beishir. ah ah hawkiss are perfectly adapted to the frigid water, but lucas miller is pushed to his limits and beyond. on a day like today he burns around 5000 calories. after 4 diving sessions, it's time to call it a day. is offered if we're going to leave them in peace. the weather is deteriorating visibility. you starting to get cool. it can be dangerous. if you push your luck too far. hell sort of

a snow storm is building up its height time. they left the marine. biologist is not only interested in the arctic, he goes diving all over the world. we spend 6 months of the year at a marine national park off the coast of mozambique. here he's doing research in to endangered shock species for his doctoral thesis, focusing especially on both shocks. he takes water samples and then analyzes them with special filters for traces of genetic material left by the shocks. that way he can tell exactly where they've bain. he and his colleagues also work with microphones anchored to the sea floor. the microphones pick up signals from shocks that are tagged with transmitters. that way the ranges know exactly where the shocks are and can protect them more effectively. philip is. amelia found unlocked

the marine life his experiencing huge strength from human activity. was mangrove forests cleared to make way for shrimp farms, entire coastal june's being leveled for sand mines. and then you have uh, oil drilling and over fishing out of here as a marine scientist. i can't just stand by and watch these local stress factors destroying nature here along with global climate change that's endangering wonderful reserves like this blue savannah or torn truck to viet a blows up on i am the gotten back to no way it's late, but lucas miller is came to analyze the days material and study the behavior of the yorkers. dean from its own d, v of issamottom. the information we've collected about where the all cars are located. we pass that on to local scientists straight away lenses which few. and i spend a lot of time studying buick has behavior towards me am. and to put that into context

of what i'm learning each evening about the ecosystem. and what other experts here are teaching mainstay dazzles another expert for me by when one of those experts is ever to mo, from the norwegian institute for nature research, he spent several weeks a year out at sea. his research is focused on humpback whales, and ogres, or killer whales. huge mammals that a good at adapting to changes in their environment. all animals live in the sea will at some point be affected by the effect of climate change and in one way or another. and but both killer wilson humbug wills are quite an adaptive so they are a generalist species. that means that they are, can eat different. so sources of food, they can withstand a large variation in environmental variation and,

and they can travel over large distances. other species can't adapt to climate change so easily, including seals, ad, walruses. they live on the ice, a habitat that steadily shrinking. finding food is becoming increasingly difficult . oak is and humpback whales, on the other hand, have benefited from the change. as more ice melts, they have a larger area in which to hunt. but even they aren't safe from human activity. the noise of the fishing troll is along with a growing number of tourist boats is affecting the whale's ability to communicate, navigate and hun. huh. they have to be louder in order to, to communicate with each other, or it's simply not possible anymore for them to communicate with each other. and

that means that they've most likely leave the area. and then of course, there is a pollution, there's basically the accumulation of fha heavy metals in india, in the marine footwear many kiddos have alarming amounts of, of having metals and other pollutants in india, blubber kit. it's especially problematic when all kids and humpback whales run into fishing boats up to $100.00 can gather around a single boat drawn by all the herring in the huge nets. ringback was possible for cannibal to go over the edge of the nets and then into the, into the net, or you can for amber coil and, and that, that can be dangerous because they, they can drown in those, in those nets. and, and it's, it's, it's quite a big problem when that happens, because there's no really good way to get a will out of the net or other than to open the nets. but that means that the

entire hiring catch most of the hiring is, is already debt by the time will be, will be lost. and that is some, it's, it's not only a financial problem for the fission, but it's, it's even illegal to the, that's the ha, by in the coast to town of share boy draws fishing boats from across norway, the regions, industrial fisheries with their huge trawlers have benefited from climate change, that's because the warmer temperatures further south have driven numerous new fish species into no wage in waters. this feature is just changing over the next big, full casting out. again. fishing for harring mainly takes place in the hours of darkness when the fish are closer to the surface. what you have seen is that the hurrying is moving may be because for luring more and more north. when it comes to the cof. ricardo the 3rd cold, for example in the salt is sir,

is struggling. but i will call to this i live. i don't know. maybe it's so if i'm up, maybe it's a blue shadow mom, and maybe it's too much tricia. this factory in sheer boy processes many tons of fish every day before exporting them all over europe. they mainly deal with herring and to cod. but he had to a lot has changed in 15 years. i've been in this industry that that proficio increased at 4 degrees or degrees. when we started up in the north, there was only small cold milk much school. with temperature went up cold, calming, moving, moving more north. so in the end it might be that the cold ends up in there are

some, some boy on a pettus and never sees the catch made by the huge troll is all the official process directly on board. that trend has seen his workload plummet. petterson used to have 80 employees. now he only has 15. he plans to retire soon. his son will probably have to sell the business fishes like pen davidson who go out in small boats are also struggling. today he caught just 200 kilos of cod and 50 of harry. he and his wife travelled here from southern no way hoping for a catch of a 1000 kilos a day. he's also worried about the future. no, it's bigger boats and they go far out in the sea so they will, they can get the fish anyway. this can go or talk to mas from the coast.

and if you want to go for you need more, more safety equipment than for your radio and everything. so if you're out of cold close to the costs, we will have to think of something else. to live. for lucas miller, it's day 3 out on the water. each day the temperature drops a few more degrees. suddenly he spots humpback whales in the distance. it's you go, what do you think it's ah, let's check here. the side go bit farther. give it a bit more and then we draw. the team is hoping for the rare opportunity to listen in on humpback whales. they

lower a hydrophone into the water with a one. thus, as the company, that's the whales communicating with each other, coordinating their hunt this, it's amazing because it's so rare for us to be able to listen in on these wireless . it's pretty special on the platter, humpback whales grow up to 18 meters long and can weigh as much as $35.00 tons. ah. they mainly feed on plankton and crill. if climate change triggers even the smallest shift at the base of the complex food chain, even the giant humpbacks will eventually be effected.

graham could 100 as the planet cliffs taylor the pistol. fiona creal, a small crustaceans that occur in swarms forming a bio mass of up to 400000000 tons under the arctic or antarctic ice down. as the ice mill is thick, the habitat that the cruel need to thrive is also shrinking unbox. and that can lead to a dropping crill stalks over time. which could affect many other species that depend on crill zalman or consequence ma'am. feel under till a different color pinkson. ah. diving with a humpback whale is something even lucas miller has never experienced. but the water temperature today is just 3 degrees celsius. the divers soon have to leave the water. they get dressed quickly and head back to the harbor.

lucas miller can't imagine life without the sea. he's happy to face every challenge that his work presents him. the old sounds of shirts under fixes on the protecting the ocean and making sure that maybe my children or future generations will be able to experience the magic of the ocean. my that's my mission live. that's my purpose in life mine, i'm sure. and i couldn't imagine anything better limbs of every 2nd that i spend in the oceans, whether it's cold or warm it whether i'm with sharks or orchestra. karl is a 2nd that was worth living. i or i'm an orca is another. and as a corner this, that is to live but our oceans are under threat. the entire moraine ecosystem could become de stabilized if climate change continues to advance worldwide

ecologist underway fina is deeply concerned. mostly the, the, the wall is changing to quickly. it's changing because of our oil activities. my work is something that is bringing me to to a heart high degree is bringing suddenness. the impact of global warming is especially pronounced in the north and south pole, where once huge expanse is advised and snow reflected the energy of the sun. now dark areas of water are absorbing the heat. we talked about the global temperature and increasing by one degree in the 1st century. and the are to cause extreme savalst $2.00 to $3.00 degrees increase in temperature over the sing, tongue period. during the arctic we're really experiencing what the rest of the globe may see. very soon built comes 4 folding. positive to the side is the aquarium in the city of thompson has a number of species from the region onto

a plane as says it's already clear which species will lose at most in the process of climate change. these are some of this case is that the most threatened by a claim we're changing the arctic for people to boredom. they have small size and they don't move so much. so they are very, is approach the bigger predators that come from the boil area in the barren seems like the bigger cods, or wolfish or other other fish vicious. but mammals that require extremely cold conditions are also affected. polar bears are struggling to find food. in desperation, they've started 18 reindeer and birds even if they try to exploit new systems, it doesn't mean that they will survive nuclear well. science is really depend on the blubber of seals, which is high in energy that the polar bear needs. so the polar bear has been eating egg strong birth nests and things vall boards and that's just not enough for

them to come when thing the energy supply. but find a says, it's not too late. if we take action immediately to say both our environment and ourselves, we have been living on the plane into this curtis table for the past many thousands of years. and now we're making it christmas changed the way the function in the way that goes way faster than we thought else can adapt to both her biologically but also culturally. so it's true that because systems change and maybe they become something else, they maybe come something more impoverished or, or maybe something different. the question is, are we able to adapt to that? back to lucas miller? it's his last day out on the boat. he still hasn't managed to film orcus hunting in the school of harry norman smith of iowa. we now have an air temperature of minus 4

to minus 8 degrees and water temperature of $4.00 to 0 degrees them was so salt water at freezing point, we're pumped on. you notice that a hot shower and a trip to the sauna just aren't enough to warm up afterwards again, lucas was off to them. the skipper worn same of the risks he faces. the good getting up with her me a very fast, and it's quite dangerous. because your brain is not thinking straight. do you think you're warm and you start strip in the you actually just remind her and get me or send me the situation. but lucas mila remains undeterred. he's received word that a bad a 100 orkeys are hunting, not far from the coast line. just 15 minutes after leaving port. he's on his 1st. hey, this is the moment he's been waiting for. a huge swarm of harry has arrived.

the oak is not long in coming by blowing air and swinging their tails. the oak is work as a team to drive the herring to the surface and city will be done in in helix. one of them will lin swim into the group of herring bombs and with a targeted switch of the tail take out a whole sway. the fish duncan and sullen or yorkers can then goble up the hearing. and in some cases, you just find certain bits of hearing afterwards. the title of yorkers suck away the most nutritious parts of the fish and then spit out the head and owns them the copy one to great and good hours. he knows the oak is could kill

him any time if they wanted to even the planets, largest animal. the blue whale has been hunted and eaten by orcus and so has the great white shock. but oak is in the wild, have never been known to kill humans. diving into the water repeatedly in these temperatures and then sitting in the cold wind is exhausting. so i can hardly pull my socks own or feel my fingers on my feet of be numb for the past hour. i'm sure i've got cramp in my calf muscles of the semester. at some point, you just have to concede that we humans don't belong here. the ocean is stronger. and so now after a life changing day, we're heading home. all moraine climate change is advancing a pace and seems almost unstoppable. ultimately,

it will be humanity that decides the future of our ocean's. glimmer the theft ish. it breaks my heart when i'm out on the ocean, and i see how deeply we are impacting the lives of these animals that are just as intelligent as we are. if not more so it's hard to swallow here is to show on and whether we're impacting them directly through excess noise or marine pollution or indirectly by robbing them of all food. it's all deeply concerning. to me. i fired full survivor in because i don't want to be the last generation that has the privilege of being with these mammals off my courses. org. then even in to 3 or 400 years time, i want the legends to continue of noise, great black and white predators again and get fun. did shots wise, an oil on? no eggs? ah ah,

ah. is consumerism good or evil? how does the candy wrapper from germany end up in a river in malaysia? is basmati just the type of rice or the specific brand, the brain in packaging? why do we reach for certain products? it's all about marketing. made in germany. in 30 minutes on d w. o blue ah
