offer 2 meetings for media professionals in times of crisis. the global media for june 2020 to get your ticket. now, nico is in germany to learn german lodge. benita, why not learn with him? d w e learning course, glucose fake. ah ah, the arctic pond to a giant ocean credits of the oka 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 thread from climate change

. lucas mila is that 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 laid, forbidden broaden the fuel woods here, a deep and wind. so finding the oak as takes a bit of luck every day, they could be somewhere else, or wherever they are

a hearing. they're an 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 the knocker towers law. and in most cases, we don't have the motivation. that's the ability my, or the knowledge to bring those habitats back. fish, we don't even understand how they work today. they're not profiting, busy, hopefully. 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. and your 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 tick the very out of here. me the team also includes underwood's a camera man, leonard, a horse and felt that is the font by you have the black and white contrast of the fuel. the waves coming up, the wind whips up the waves and sometimes it looks like there are a whales coming up and breathing, but it's off. but it's just wishful thinking. my darkness is closing in. it's early afternoon and they freezing as they returned to the harbor was lloyd's 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 citing of dignity so we can get them on camera for the lens. and so 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 kula conditions. those who can't cover such huge distances will presumably die out. and

that will have consequences for humans to premier z one up from fish for more than 750000000 people worldwide in a 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 can't continue like this indefinitely. as christopher simon from germany's institute of baltic sea fisheries knows all too well that he had a few, that 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 need 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 herring stocks has dropped significantly, which will be reflected in the harvest in the coming years. i'm shocked as a productivity for this doc is half what it was 30 years ago because of climate change and awful and that will directly impact our coastal fisher research or mit adolfo for lucas miller. it's day 2 in the arctic. ah, 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 a 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. all right. thanks. episode figure. we're ready to go for the lifting those, but soon they get their 1st indication that harring our round birds circling above the water and just a few seconds later the oak is arrived. the 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. all right, let's all that. i took my last breath and dived. huh. it's like another world. you're waiting in the bits, these huge shadows to approach sort of just then the entire po wins past the school . i have like its own. 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 venice . don't spider i. monmouth didn't younger to 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 hawkers 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 on friday, we're going to leave them in peace. the weather's deteriorating. visibility is starting to get cool. it can be dangerous. if you push your luck too far, like hell sort of a snow storm is building up. it's high time. they left the marine biologist is not only interested in the arctic. he goes diving all over the world.

he spent 6 months of the year at a marine national park off the coast of mozambique. here he's doing research into endangered shark species for his doctoral thesis, focusing especially on bull shocks. he takes water samples and then analyzes them with special filters for traces of genetic material left by the sharks. that way he can tell exactly where they've been. he and his colleagues also work with microphones anchored to the sea floor. the microphones pick up signals from sharks 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 is experiencing huge stress from human activity. was mangrove forests cleared to make way for shrimp farms, entire coastal june. so being leveled for sand mines and then you have 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 is endangering wonderful reserves like this blue savannah or torn truck to be here, the blows up on i am, but also 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 a to interview because i'm out of 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 the oak as 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 a teaching me. thus was another expense 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 orchids, or killer whales. huge mammals that are good at adapting to changes in their environment. all animals live in the sea will at some point be affected by the effects of climate change in one way or another. and but both killer wilson humbug rules are quite adaptive. so they are an a generalist species, that means that they are, can eat different. so sources of food, they can withstand large variation in an environmental variation and, and they can travel over large distances. other species can't adapt to climate change so easily, including seals and wall versus 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 hunter 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 heavy metals in india, in the marine footwear many killer wills, have alarming amounts of,

of having metals and other pollutants in india, blubber. kit it's especially problematic when oak is 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. ringback ringback as possible for cannibal to go over the edge of the nets and then into the, into the net or even for amber crew. 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 to net other them to open the nets. but that means that the entire hiring catch most of the hiring use 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 that's the ha,

by in the coastal town of cher. voy, draws fishing boats from across norway, the regions, industrial fisheries with their huge trawlers have benefited from climate change. that's because the warm temperatures further south have driven numerous new fish species into norwegian waters. this fisher is just changing over the net before casting out again. fishing, the 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. maybe because they're moving more and more north. when it comes to the cove, we heard of the cold, for example in the salt is a struggling. but i will. course it is. so i don't know. maybe it's so climb up. maybe it's the flu,

shall i don't know. and maybe it's too much visual. this factory in sheer boy processes many tons of fish every day before exporting them all over europe. they mainly deal with herring and 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, but temperature went up cold, calming, moving, moving more north. for in the end it might be that the cold and so the rocks and 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 pear davidson who go out in small boats are also struggling. today he caught just 200 kilos of cod and 50 of herring. 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 undergo for alt on the sea, so they will, they can get the fish anyway. this can go talk to mas from the coast when, if you want to go for you need more, more safety, chris mountain figure radio and everything. so if you eltoff called close to the

coasts, 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. if you go, what do you think it's ah blitzer check here the side go both farther vividly 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. does the sticker with the whales communicating with each other, coordinating their hunt? it's amazing because it's so rare for us to be able to listen in on these wireless or it's pretty special on the glad filter. humpback whales grow up to 18 meters long and can weigh as much as 35 tons they mainly feed on plankton and crill. if climate change trig is even the smallest shift at the base of the complex food chain, even the giant humpbacks will eventually be effected. graham could 100 as this planet cliffs. taylor di, pistol fuel not 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 her unbox. and that can lead to a dropping crill stalks over time. which could effect many other species that depend on crill was almost a consequence ma'am. feel that under tiller different companies, some 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 see. he's happy to face every challenge

that his work presents him then old sounds, the shirts mondor fixes on the protecting the o and making sure that maybe my children or future generations will be able to experience the magic of the ocean. the my that's my mission that live, that's my purpose in life. my them so and i couldn't imagine anything better. them said every 2nd that i spend in the ocean, whether it's cold or warm, 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 ecologists under a finer is deeply concerned. mostly the that the wall is changing too quickly in stretching because of are all activities. my work is something that is bringing me

to to a high degree is bringing southerners. the impact of global warming is especially pronounced in the north and south pole, where once huge expanses of ice and snow reflected the energy of the sun. now dark areas of water are absorbing the heat. we talked about the global temperature increasing by one degree in the 1st century. and the article experience about $2.00 to $3.00 degrees. increasing comparative goes way faster than weight loss helps, can adapt to both her biologically, but also culturally. so it's true that because history change and maybe they become some pianos, they maybe consulting more impoverished or, or may be 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 or curse hunting in a 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 to 0 degrees watts. so salt water, correct freezing point. the a point on you notice that a hot shower and a trip to the sooner just aren't enough to warm up afterwards. lucas was off to them. this skipper warns him 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. you think you're warm and you start strip in the you actually just remind her the deadline. give me your sending me the situation. but lucas miller remains undeterred. he's received word that about a 100 orchestra hunting not far from the coast line. just 15 minutes after leaving port. he's on his 1st dive. 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. i'm city it'll be done in in helix. one of them will, lynn swim into the group of herring bumps and with a targeted switch of the tail tank 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 herring afterwards, them to tile. yorkers suck away the most nutritious parts of the fish and then spit out the head and owns them. cup would be great and good owls he knows the oak is could kill him any time if they wanted to. even the planets,

largest animals, the blue whale has been hunted and eaten by all his. so has the great white shark, but oak is in the wild, have never been known to kill humans. diving into the water repeatedly in these sandwiches and then sitting in the cold wind is exhausting. so i can hardly pull my socks own or feel my fingers on my feet. have been um for the past hour. i'm sure i've got cramp in my calf muscles of the submissions. 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 marine climate change is advancing a pace and seems almost unstoppable. ultimately,

it will be humanity that decides the future of erosions glimmer, the theft and ish. it breaks my heart when i'm out on the ocean, and i see how deeply we're 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 rubbing them of all food. so it's all deeply concerning to me. i fired for survivor 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 23 or 400 years time big, i want the legends to continue of noise, great black and white predators again and get from. did france weiss, an oil on know, eggs landscape
