hardware and humanity and make doing it the way. this is a show about science i find. everything. here. ok so this conversion they see behind me is a bunch of people already getting ready to dive in the great barrier for the first time much like me. techno is married to davison travel to queensland to see firsthand one of the seven natural wonders of the wild. and to explore the scientific efforts to save it. ask a thousand different people to describe what makes australia's great barrier reef special and you'll get a thousand different answers and sometimes none at all just to be new silence

a nod to the fact that there exist things on this earth so beautiful he defied description and yet for all its capacity to inspire us on an intimate level it's when we step back that we are even more amazed the great barrier reef. covers three hundred forty five thousand square kilometers roughly the size of germany it stretches twenty three hundred kilometers in length nearly equal to the entire coastline of china and it's the only living structure on earth that can be seen from space and therein lies its vulnerability because it lives it can also die. although coral reefs cover less than two percent of the ocean floor twenty five percent of all marine life depend on them for their survival and yet according to the world resources institute by the year two thousand and fifty nearly all coral reefs worldwide including the great barrier reef will be threatened with death

a scientific prediction that if correct will mean the disappearance of one of the earth's most vital and enduring ecosystems within most of our lifetimes. off the coast of northeastern australia where the great barrier reef meets the shallows i meet with over who goldberg director of the global change institute at the university of queensland for him a hope for the best approach is no longer on the table i mean world wars we're quite willing to spend half of the supposedly come solving a problem this is as big or even bigger than a world war and we need to get those sort of resources and we need to get everyone behind the solutions solutions to problems that are becoming legion. there are multiple stresses that face colorists like the great barrier reef is sediments a new transit flying down rivers and smothering corals and other organisms that has been too much fishing in some cases where we've knocked out case bases but the real

showstoppers now are the global changes that we're inflicting on on coral reefs and it's the showstoppers that could be potentially catastrophic according to the world resources institute the absorption of an increased level of atmospheric carbon dioxide into the oceans has caused them to. become more acidic this change in water chemistry inhibits the ability of corals whose skeletons are composed of calcium carbonate to grow and increase in carbon dioxide emissions has also led to a trapped atmosphere of heat which in turn has led to higher water temperatures warmer water disrupts the symbiotic relationship that a coral has with a micro algae called. the belly is responsible for the corals food supply and when it leaves the coral begins to starve the effect turns the coral white and is known as coral bleaching the heart of the problem is this scientific models show both

ocean acidification and ocean temperatures spiking to unprecedented levels over the next one hundred years levels that without intervention would spell the end of coral reefs. it was against this backdrop that in two thousand and sixteen the great barrier reef experienced one of the most severe bleaching episodes ever recorded initial surveys by researchers at the a.r.c center of excellence for coral reef studies put the areas affected by bleaching at ninety three percent and estimates about the resulting mortality figures ran the gamut few climate related events in history have captured the media and the public's attention more it included an obituary for the great barrier reef that quickly went viral it sent the g.r.s. tourism industry into an uproar and even gave the scientific community pause and actual mortality survey conducted in late two thousand and sixteen also by the a.r.c center of excellence for coral reef studies proved a mixed bag the northern third of the reef was devastated losing an estimated sixty

five percent of live coral coverage but the lower two thirds of the reef the area where the vast majority of reef tourism occurs escaped relatively unharmed spared by cooler waters from the coral sea. just outside the city of townsville which sits at the southern tip of the great barrier reef a group of scientists are fighting to save coral reefs not just from bleaching events now but from the effects of climate change yet to come one of the goals of marine research in a time of global change is to gain insight into how marine systems like the great barrier reef may look into the future to achieve this researchers need to replicate and manipulate ocean conditions in controlled environments in other words literally bringing the ocean into the lab and that is exactly what is being done at the most advanced research aquarium in the world australia's national sea simulator. a

thirty five million dollars facility completely dedicated to tropical marine research for a scientific discipline whose researchers are used to working with simple tubs of water system is nothing short of revolutionary that's giving us the opportunity to do the research that we've not been able to do before dr nicole webster is one of the lead coral scientists working at c so sorry you know in the past if we were trying to do an experiment about climate change free markets and corals and stick them in a sort of small nalley bin size tank then hate them up a little bit but it doesn't really very closely reflect what's actually happening out on the brain and the driving idea behind system is that if you have the tools and technology to accurately reflect conditions on the reef today then you can accurately replicate what conditions on the reef will look like tomorrow yes so we've got a number of tanks here what what's going on this is our newest experiment which

we're calling evolution twenty one and it's about trying to assess what's going to happen in terms of evolution in the twenty first century but these really large tanks which enable us to establish these maze of pauses and one of these a cousin is that is it's not just one particular species of whole we've got all of these things in the tank tenuously that we've got corals we've got some giant plans in the tanks with but you're essentially trying to recreate the ecosystem but under controlled conditions about them and i believe the things you're interested in that's right and what we're interested in many colliding with this experiment is the temperature and the c o two so it's caught up on local climate change the surface temperatures are rising the oceans are becoming more sedate so what this experiment is is we're looking at current day condition and then we're looking at conditions which are projected by the i.p.c.c. we choose the top and mental panel climate change on conditions which predicted for the year twenty fifty and in conditions which are projected to be twenty one

hundred three so. of tanks one an ambient tank that reflects temperature and ph conditions as they exist on the reef today a second that reflects those conditions for the year twenty fifty and a third that reflects the predicted conditions in twenty one hundred. but the level of control and detail in the system goes beyond even the. tell me a little bit about the tanks that we're looking at here i know this is our ambient yes and then you're manipulating temperature and carbon dioxide so that right give me give me some of the stuff here like a city and be a tank is set at about one hundred ten hot and know you have a dark side which is currently condition so to generate out endian values we've taken the last ten years of temperature data and we've averaged that and that for this day is about ninety nine point four degrees or something like that so that would that would be the temperature at this particular time on this particular day

in the ambient conditions and then how are you manipulating the conditions off of your baseline here yeah your other train so it's a three on top of the outside conditions or ten six hundred i t. which is what's being projected particularly in hot million or i'm twenty feet deep and nine hundred twenty one hundred so that's what they rejected by the i.p.c.c. with the temperature how we take the temperature values from the ambient thanks and then we apply plus one degree offset perhaps twenty fifty set of conditions and a plus two degree offset for at twenty one hundred which is that level of control and manipulation is available to every experimental room at the sea some facility and all of their tanks it's a system that requires nearly one hundred kilometers of piping seven hundred to eight hundred thousand liters of new seawater daily and a computer system that not only must keep water temperatures and ph levels accurate to within one hundredth of one percent but also controls it all through the touch

of a button keeping it all running twenty four seven is the job of operations manager craig humphrey they just for example or bring up an experiment that is within your climate train generation divination ok so the example here is is that we have the. temperature one each one of these rectangles represents i think tank with an ordinary car or front ok so some of these are some of the tanks that we've already looked out exactly thirty temperature one is indicated by these color rectangles each color represents a different page ok there is a different concentration of c o two yes exactly so what we have in this room we have four different temperatures we have four different pages and every combination of these sixteen different water is running into this room so i'll just let temperature three for example i can see the red thanks for trying to say this is there any good enough time but all of the cutting edge research that system's technology and engineering now allows ultimately one thing stands out we've never

been able to run such a long time experiments because the quality of the water and the good quality of the controls put sophisticated enough that we could actually produce offspring after all it's not whether the corals on the reef today will be able to adapt and exist on the reefs of two thousand and fifty and twenty one hundred it's whether their descendants will researchers are seeking to determine not just whether corals can be conditioned to withstand future ocean conditions but whether those manipulated corals can pass those survival traits on to future generations the process is known as assisted evolution so the main goal of this is the evolution for a day is to develop still. hasn't monsters in the climate so it's better to withstand high power from the city because. if we can perhaps mix from the strong the skeletons hasa grown closer i get an ideal world all of the about madeline van oppen is

a principal research scientist at ames and leads its assisted evolution program and how are you going about this to walk me through some of the nuts and bolts of how this research goes about we are and crossing different species a and rational basis at home like meat. and provide new characteristics to that that they can and if they do. what we were then the son of three grown these high risk pools on the public the future ocean and this isn't place where you have nothing else left and think those individuals that perform to take you out i'm really curious about this how do you go about the cross-fertilization what are the what are the mechanics involved in creating a coral yes a person would need to send a team out to the rig so to collect whole phone use that have ritual acts so we need to go around and pick those ponies that are ready to go. as seen in this video shot at regular speed the collected coral colonies are brought back to the sea

simulator to spawn. the corals packaged both sperm and egg into what are called bundles when they are ready to release the coral pushes the bundles through the mouth openings of their polyps creating a distinct visual image i miss some of my christmas space like decorated christmas presents waiting with them look like for once again this is a those bomb no stay close to the surface of the bed and we kind of scoop them up with various and hard facts and remember to bring them into our rearing area the bundles are than separated into sperm and egg and crossbred according to the breeding match scientists wish to attain selected sperm and egg are reintroduced to each other through and in vitro process two hours later fertilization is complete and what are now coral larvae are moved into rearing tanks were dr lena berry looks after them while they are at their most vulnerable so point out to me what i'm looking at i mean you can look like little dust particles but there are baby corals

that's exactly right and each one of those can grow into food and karo you're. lucky enough to find the right spot on the me and that they have the right conditions so therefore it is old that's what's going to happen come next so now we're going to take these small larvae and we're going to actually expose them to a very hot temperatures to see whether we can identify when it is under these conditions well that the limits on them and individuals from from this function all right and you're doing that just next door just over here all right so baby coral go from those tanks over there and they wind up here yeah that's right so we have the nursery on one side and over here is the sauna say this is not this is essentially where we space the lab it's a very tough and we did that for about three days to see which ones

survive not all coral spawn them. lab are crossbred some are simply manipulated or evolved but the endgame is the same all right so this is one of the rooms where you're you have an experiment running and i see little plugs with teeny tiny little girl wire these guys so important this this little corner somebody's euro and but it was initially it's several dozen a lot of those brats here in the sea simulator and hopefully and then brought another to you this and this whole actually able to reproduce itself with the project that you have going on i mean it seems to me like it's it's very solutions oriented right i mean a lot of the time you know scientists are are documenting the decline of a system and that can be a very demoralizing thing to do but in this case here you're trying to come up with a solution here what is in your opinion what is the end game of of your research what is the final result here are we are you driven to action i think is first that

we could improve the success of requests and i certainly am but also we hope that we will be able to increase resilience around the family how things are in systems vibrating maybe someone some of those snow and hans poles you know releasing them into the environment and bringing with the native force we would hope that that would increase resilience and loosen them up so negatively in fact that for over two goldberg the threat to coral reefs goes beyond simply the concerns of scientists when you take what coal reefs represent to paypal and this is the amazing numbers right so there's an estimated five hundred million people on the planet who come to call results on a daily basis to get food and income now that's about one in every twelve people that is dependent on coral reefs worldwide four hours north of the. the syllabi is

the port city of cannes the primary maritime gateway to the great barrier reef more than two million people visit the great barrier reef every year many of them beginning their tour right here and that's what we're here to do to see the reef through the eyes of those who make it an economic engine as well as an ecological one. call mckenzie is the executive director of the association of marine park tourism operators his job is to represent the interests of the g.b. r.s. tourism industry both with the government and with the scientific community look there is no doubt that tourism is the backbone of the of the kane's region and that's underpinned by the fact that something like justin keynes the sixty thousand people employed in the marine tourism industry across the whole industry it's a six billion dollar industry and employs about sixty three thousand people it's

a six billion dollar industry that's huge that's a six billion a year just billion a year just pointed in the last especially last couple of years with a follow up of a huge leaching event that was reported in the media you know the great barrier reef has really received a lot of attention what do you think about all that publicity that's coming your way where one of the publisher he was incredibly negative and also untruthful. we had stories of no what he's free to send the wreath laying dead and dying and we've seen stories where people are written lee you treat for the great barrier reef how has that impacted the tourism activities in the perception of tourism here in cannes what good will bleaching event happen this year so like in the season most people who are already booked their trips to coming out so we've had a really good tourism season i worry about next year and next year is where the people who were sitting in in america or in in europe are going to go or should we get the barrier of should we go somewhere else the morning that i choose to go see

the reef for myself starts off ominously a squall pushes through cannes luckily blowing out just as quickly as it blew in. like the thousands of travelers from around the world do each day i book a trip on one of the reef leads boats the vessel is the reef cast the captain is mark albert. the rate we're going to today is briggs right. you know to go models southeast of cannes saw it way go to one briggs right is about six made his day perfect for in tried but all around greg's right his water that's thirty five to forty made his day so you have the snow ice cold water of it's coming up in the rain bringing all these nutrients into the right excellent sought for fish and flight simming in an aquarium the trip out to briggs' reef is about an hour and forty minutes and without land markers it's seemingly a trip to the middle of the ocean until you arrive and the water settles and you

are able to see just under the surface and the perspective of where you are and how large it is begins to settle it. once for moored it's a simple equation the quicker you get in the water the more time you get to spend there. it's not working out dive boat that we're on right now michael ribeiro reef is one of the world's leading natural treasures a channel for sure i'm super from lives and i'm going to bounce i'm about to dive off a boat ready to dive there check out the amazing coral reef the bucket list check off very. well. from above the water surface the break will be a brief appearance majestic but still. the corals looking like rocks for which they are often mistaken. it's when you get beneath the surface of the water that you are truly able to appreciate what's meant by the phrase rain forest of the sea.

we're diving in the middle third of the great barrier reef which has been largely spared the devastation felt by the g.b. has northern third there are signs of bleaching but overall the reef is beautiful and full of life. for myself it's especially rewarding to see the contents of the ames mizo cozzens full. life out in their natural environment. so i am the absolute last person out of the water it was amazing down there we saw fan corals brain corals we saw all sorts of fish chaya clams probably going to stay there for another couple hours but exhausting lunch back ends and off we go. we returned to cannes with the rest of the briefly and the thousands of tourists

they ferried to one of the world's natural wonders for many it was their first time visiting the g.b. are the looming question will this generation be the last we're able to do so for those who seek to save the reef through science and for those whose livelihoods depend upon it the answer is no provided that action is taken if we continue on a current pathway where we're pumping c o two into the atmosphere worth it if i mean oceans we won't have coral reefs within twenty thirty forty years from now business as usual is going to be devastating but even if we do something to to halt or to mitigate some of the impacts of climate change we're as a as a human society going to have to live with the fact that we're going to lose a lot of coral reefs all right we're going to lose a lot of color race but there's no doubt about it if we if we followed the paris agreement where we cut greenhouse gases such that temperatures don't rise above two

degrees and kept well below its estimate it will still lose ninety percent of coral reefs but the important thing is that if we done. fulfill the paris agreement. they were mid century they go on thinking we're going to have a good healthy rate for the next five ten years maybe even longer even if we don't do much more than what we're currently doing but if we really want to come to grips with it we're going to be on the comma only we want people to think that there is some hope and there is. hope i think that. is incredible in the trouble it can cause but it's also incredible in terms of the solutions and the fixes that it can. they're all solution and the great barrier. you know saveable most of that we can cite but we've got to start with. that we've got a really good. while the great barrier reef. action

on his behalf. time something that the new. techno. next time. we here to jerusalem bureau covered israeli palestinian affairs we cover the story

with a lot of internet we cover it with that we don't dip in and out of the story we have a presence here all the time apart from being a cameraman it's also very important to be a journalist to know the story very well before going into the fields covering the united nations and global the policy for al-jazeera english is pretty incredible this is where talks happen and what happens there matters. what are you seeing like how i might a suspected terrorist people of all faiths fell victim to a suicide bomber in manchester but if the bomb was indiscriminate was the placing of blame this is nothing to do with us this is about an individual who's psycho you know nobody could do this unless they were completely unhinged how much just as muslims responded to challenging questions in the aftermath of the deadly attack people in power manchester united at this time want to.

jews here. where every. bone in circus is on a mission to help local children break the poverty cycle one on east follows their journey of sacrifice become top class performers. when one used at this time and now to zero. hello i'm daryn join into how the program out of the top stories here u.s. president donald trump has laid out an aggressive new strategy on iran he says he won't certify terence compliance with a twenty fifty nuclear deal and is calling on congress to put more pressure on

iran's missile program kimberly harkat reports from washington d.c. he's often threatened to tear out the landmark deal with iran but in the end u.s. president donald trump stopped short of pulling out of the two thousand and fifteen agreement to limit its nuclear program for now and even though his own administration has twice certified that iran is complying with the deal he now says he won't do it again i am announcing today that we cannot and will not make this certification we will not continue down a path whose predictable conclusion is more violence more terror and the very real threat of iran's nuclear breakout that is why i am directing my administer.
