>> it's overwhelming to see this many people that have perished. >> lost lives are re-lived... >> all of these people shouldn't be dead. >> will there differences bring them together, or tear them apart. >> the only way to find out is to see it yourselves. >> which side of the fence are you on? borderland only on al jazeera america >> >> sna this is al jazeera america. live from new york city, i'm greg betzold, with a look at the top stories. >> fighting back - ukraine pushing back against what it considers are terrorists taking hold of government buildings. >> the blame game - who is behind more chemical attacks in syria. >> huge forest fires taking lives in the chilean coast. >> for hundreds of years, mariners used lithographic maps. why the is federal government

getting out of the business of printing them. i'm tonya moseley - with the april. -- with the answer. >> on this sunday, the u.n. second will be meeting in a few hours about the renewed threat of violence if eastern ukraine. that country launched what it calls an anti-terrorist operation. the target - pro-russian militants who seized a police station in the city of slovyansk. one officer was killed, five hurt. people were warned to stay indoors and away from windows. >> hoda abdel-hamid is in slovyansk, about 100 miles from the russian border muchized the building is still under control of the gun me who seized it on saturday. they appeared to be holed up inside. there's no sign of the anti-terror operation that the ukrainian interior americans

warned of. the people in the building at the time looks like they have fled much the street that is been barricaded. on top of the barricades me are unarmed, they are holding plastic shields and wearing helmets and are counting on the support of hundreds of resident of slovyansk, who came to show their appreciation. the government of ukraine is probably fearing that there is a replay happening here in eastern ukraine where in several towns did cities, either security buildings or lobing it will councils -- local councils have been taken obvious, and the reality that is developing is that the government of ukraine has not been able to counter. >> for more on the escalating crisis in eastern ukraine we turn to kim vinnell. >> tensions are spilling over in

eastern ukraine. ukrainian authorities say this e have launched an anti-terrorist operation. this video, which can't be independently verified appears to show a man taking cover, nearby a second sits apparently lifeless. in the city center pro-russian activists remain in control of the police station. ukrainian forces on sunday tried to retake the building, but retreated reportedly because of a risk to the public. >> translation: we are the residents of slovyansk. the national guard is coming here. there has been a shoot out this morning. we have nothing to hide. here is my face. i want to ask comrade vladimir putin he promised to protect us. please come here in protect us. >> this was the scene on

saturday, and the nearby city. amateur city shows the moment gunmen stormed the police station. after a tense stand off shots were fired and pro-russian activists moved in. a day later, the station remains under their control. >> when we were given access to the building, we were told we shouldn't film the outer barricades, just the front of the station people here underweary of how the unrest should be portrayed. >> people here maintaining the call for a referendum. >> downesque is like a bar. it is asleep. when you wake up the bear, there'll be trouble. please, do not ask me how far we will go go. >> this city council has been taken obvious and protest scores blocked entrance and exits to the military airfield. a few ukrainian -- they say if

ukrainian special forces return, they will not get past. >> many maintain that protesters do not represent the region, protests are occurring, and the use of force could be difficult. >> the ukrainian president says armed russians are launching the initiatives and launched its own campaign. >> translation: the national security and dense council made a decision to start a full-scale anti-terrorism operation. we will not allow russia to repeat the scenario in ukraine. >> the claims of using armed forces was said to be outrageous, he said:

>> u.s. says russia is behind the escalation of violence in eastern ukraine. washington warns more sanctions could be on the way. tom ackerman is live in washington with more on this. samantha powell, the u.s. ambassador for the u.n. had strong words for russia today. >> yes, she echoed the words of secretary of state john kerry in his call to his russian counterpart pardon saturday, in which he said that the russian would have a de-escalate what was going on in eastern ukraine, and move back its forces on the ukrainian border. as to who is responsible for the unrest in eastern ukraine, she basically said that it was clear who was depend it. >> it has all the telltale signs of what we saw in crimea - it's professional, coordinated. there's nothing grassroots seeming about it.

the forces in each of the six or seven cities, they've been doing the assume thing. >> it bears the tell-tale signs of moscow's involvement. >> now, on another sunday talk show, senator john mccain reiterated his demand for tougher response on the part of the united states, as well as its allies. >> unless we act with firmness and strength, including giving ukrainians some weapons to defend themselves and very severe sanctions that may cost our european friends - the other thing is the ukrainians will fight. they didn't fight in crimea, and probably not. but if they - he starts moving in further encroachment in this way into eastern ukraine. they will fight. we ought to give them some weapons with which to defend

themselves. >> well, the ukrainians asked for light weapons in the form of several thousand m16 rifle, but most military experts say it's of little avail if the russians regarded that as a provocation and crossed the border. a scenario is that the rush jobs could take the land bridge connecting russia directly with crimea, and that would obviously escalate the tensions further. >> yes, major concern. we have diplomatic talks called. how important is it for the united states to work together with europe and the youn when it -- uniyour when it -- european union when it comes to the crisis. >> british foreign secretary william hague said there must be a united front. they are meeting on monday ta

talk about sanctions. the americans do not want to get ahead of the europe yeens in terms of ratcheting up sanctions. with 28 members of the e.u., and them requiring a unanimous decision on how tough, some of these countries, which are vulnerable to russian counterpressures, particularly in energy supply may be hesitant to ratchet up the conflict. the question here is to what extent they are prepared to do what senator john mccain talked about, which is sacrifice in the short term to benefit by pushing the russians back in the lopping material. >> tom ackerman live in washington. thank you. >> let's bring in the ukrainian congress committee of america, andre. on set with us. russia - not introducing the term civil war - may be concerned about a civil war.

>> what you are seeing is invasion of ukraine by russian forces. there are russian troops in ukraine, intelligence and security forces in ukraine. they have been there for years. we are getting more information from the compounds saying this many agents will be in this part of the country, this many in this part of the country. what you see is the erasure of ukraine in the maps of europe in a way that has not happened sips poland at the beginning of the 20th century. >> you think russia is taking moves to take over eastern ukraine. >> yep. >> despite the fears that a lot have that russia will not do this, it doesn't make sense for the kremlin to further aggravate the west. >> it didn't make sense for russia to invade crimea, a land that has less rain than los angeles, no land bridge to russia, has foog to give in terms of arg culture or

resources. >> the black sea fleet. >> it's not intrinsic to crimea. there was no point for it to be invaded, yet it was. now everyone is saying there's no way russia will invade ukraine. and it was. we are seeing the same people that invaded georgia, we have citizen journalists taking the pictures. these are russian forces in ukraine. it's not a separatist movement. it's not a civil war. they are people from the russian government working to destabilize ukraine and prevent an honest election. >> weakening the crimean government and having regions like donetsk more independent. >> they are independent. if you are in ukraine, you are freer as a russian than in russia itself. you can speak whatever language, worship whoever you want. you have the prospects for jobs,

which you don't have in russia. they have higher pngss and less of a -- pensions and less of a chance of production. >> the thought is that the regions could have autonomy and something the ukrainian government suggested could be a possibility. >> after 20 years, no one on the ground wanted outon me. minority language is respected in terms of the constitution of ukraine. there's no need for an additional level of autonomy, they have more freedom than lusha. >> a lot support russia, they speak russian, we see cities shut down by the protesters. that's not a lot, from indications people have, of people fighting back. >> maybe you can check the gallop poll in march. the ira institute put out, over 80% of people, southern and eastern ukraine supporting ukraine, not supporting what

happened in crimea. and the national democratic institute put out a poll saying the same thing. 90% of people are not in favour of joining russia. >> how do you explain the picture we are seeing in the news. if it is russian soldiers, as you and others allege, they came to it on their own, they must have russian support. >> the people on the streets are paid by people. they are not representing the populous. especially in donetsk. there was one day of republic of donetsk, but the state and province had no idea what was going on. it was not a national movement. over 90% of people in donetsk voted to be a part of ukraine. it was a national referendum. this is not something that came out of nowhere. now after 20 years of independence, you see political moves by russia to buy off people, propping up people like they do in all of europe.

we see in france the national front saying we support russia, they are supporting the russian citizens, there are all different political parties propped up by russia. this is why ukraine is scared. they don't see a unified west. ukraine gave up the third largest nuclear arsenal. >> all for an agreement that you do not violate our borders, now it's erased. >> the west is trying to figure out how to deal with it now. thank you for yore perspective. >> barrels of chemicals have been dropped on three main provinces across syria, including damascus. president bashar al-assad and the rebels blame each other. an attack sparked out rage on foreign leaders, this time the international community appears to have fallen silent. >> this is the aftermath of a barrel bomb attack in aleppo. people are searching for

survivors under the rubble. the government has intensified the air raid across the country. rebels say this cylinder is all that is left of a barrel bomb that exploded in the town. activists say the bombs were filled with toxic chemicals. these videos are said to show victims of the attack taken to field hospitals. >> translation: on 11 april the city was targeted, gases were all obvious the place. we went to the scene. dozens were affected. they were almost suffocated. most were elderly people, women and children. two cases were severely affected, they died. >> the syrian opposition is demanding an international having. the government blames the attack on al nusra, a group availiated with al qaeda. this is a rebel stronghold. the area bombarded by the army,

which is pushing to recapture these areas. but the rebels hold out. >> translation: this military commander explains why the fighting in hama is important. our aim is to cut off the main government supply route that links hama. those that stop the army reinforcement reaching other areas. >> rebel attacks are expanding in idlib. there, helicopter crews dropped food and weapons to soldiers, besieged for months in a military base fear the city. recent gains by the opposition in aleppo and other areas allow the rebels to send in more weapons and fighters, as fighting escalates in the coast af province of latakia. into there is much more ahead on

al jazeera america. including the end of an era for charting your progress at sea. that is next. >> i'm rob reynold's in california - with a maritime mystery - what is killing the pacific sea stars.

>> suns the early 19th century mariners relied on large clunky charts to navigate the seas. now has the national oceanic and atmospheric association made them available online. it makes them quicklier to update and safer travels. >> tonne ya moseley joins us if the center for wooden boats. this is a big change for sailors. >> it is. i am on the rem licka of a boat -- republica of a boat used by george vancouver to chart the smaller waterways in the pacific north-west. that information was printed on lithograph k paper.

these charts came out a few times a year, until recently. thanks to technology, it's different. when captain tyson trudell was two, one of his first words was boat. by six he chaired he would be a captain, charting voyages around the world. >> you're a kid, you pull the map out and think about all the laces you can go. it's the same thing. >> the nautical chart - mariners rely on them to navigate through oceans, seas and rivers, avoiding shallow areas and other hazards. printed charts are an integral part of the nautical experience. >> first of all, it's really pretty. i have a few charts on the wall in my house, like, framed. just of the ones you can get for 25 bucks. >> since 1807 charts have been the signature product of the national oceanic.

the office printed and sold them. today noah has gone high tech, providing them online where boaters, fishing mariners can view them or print on demand. those that need commercial quality can purchase the latest version on specialty shops. the days ofs buying huge lithograph maps from noah are gone. >> we are print new information, but can only print for a few years. as soon as the chart is printed, it's out of date. >> out of date compared with the real-time ability of technology, which lieutenant commander evans says evolved rapidly. he notes mariners never only just use one fom of maps. with the decline in demand for versions, printing maps was a public service they couldn't

afford. >> when the mariner paid for the chart, he or she was paying for the cost of printing and distribute k, none of the cost of collecting the data, compiling it, producing the chart was passed on to the mariner. >> this captain says unlike the charts, you can't hang a computer map on the wall. but it is up to date and more precise than ever before. the end of an era, and the evolution of nautical charting. >> now, despite all of the advancements in technology and real-time information, aspiring captains have to know how to read the lithographic charts to receive their federal licence. back to you. >> thank you. i'm glad to see you have your life jack the on in the boat. appreciate it. >> for centuries star fish have fascinated people. some consider them good luck.

scientists are worried a strange disease is killing off the sea creatures. rob reynolds has more. >> in this rocky corner of the california coast, researchers are gathering offed. they are searching rock by rock, crevice by crevice for star fish. normally many species of star fish thrive in the tide pools, an important part of a complex ecole onlyical system. today the reachers can find hardly any. >> we have only seen two sea stars, a year ago at the sail election there were 145. to go from 145 to 2 is drastic. >> star fish lived in the oceans for 450 million years. now they seem to be in trouble. up and down the pacific coast, star fish have been dying off in huge numbers.

scientists have no idea what is killing them. >> divers noticed larm numbers of dead and -- large numbers of dead and diseased sea stars in brieing columbia -- british column by an and atlanta. >>. >> it's a massive mortality event. >> divers say they have seen the disease kill in a matter of horse. >> it starts as a little white legion, and basically they get deflated and arms just come off, and kind of creep away from them. at the worst statement you'll see, like, four or five arms that have obviously spread away from the center of the body. >> scientists believe some sort of virus for bacteria is killing the sea stacks but they are baffled by why the animals have suddenly become so susceptible to the infection. pete is the top marine biols at uc santa cruise. given -- biologist at us santa cruz. given it is a pathogen and

having an affect, why now? why is the pathogen virulent now, or why has it moved were wherever it was? >> possible causes unclued manmade chemicals, ocean ac acidification, waste water discharge or warming oceans due to manmade climate change. scientists are not ruling anything out. >> a new push in the middle east peace process begins this week ahead of an april 29th deadline. the ambassador martin indyk will try to arrange new talks for july. efforts have been stalled by both sides. israel has not released prisoners and announced new settlements and territories. the palestine authority started its campaign for international recognition. for more on the peace talks join us on 8:30 eastern for our regular segment "the week

ahead". >> a check of the stop stories in a moment. life and death along the border with mexico. and later... >> i'm andrew thomas on why pacific island nations are looking to australia's king island for now they can be empowered entirely by renewable energy.

>> welcome back to al jazeera america. here are the top stories - ukraine launches an antiterrorist organizations pitting the army against pro-russian forces. the u.n. council security council meets in a few hours to discuss the threat. >> three provinces in syria hit by chemical bombs. the government blames the opposition, and the rebels the government. >> illegal immigration to the united states has been a controversial issue.

in the past six months efforts to stop people crossing the border increased dramatically. in addition, there has been a string of recent shootings involving border control agents. paul beban is on the ground in a town trading the border and -- straddling the border and mexico. >> a dusty cross and faded plastic flowers mark the spot where a boy jose antonio rodriguez died, gunned down in his home town of kagisso, mogale, mexico. this is the scorery of a boy, a border and a wall of silence. some time before 11:30 pm on october 10th, the 16-year-old died instantly when hit by a bullet in the back of the head. as he fell face down eight shots hit him in the back. at least one border pottal agent

fired from somewhere around here on top of the cliff, through the fence down into the street into mexico. why? border pat ral says jose antonio was throwing rocks. one eyewitness says he was walking down the street. if he was throwing rocks, was shooting him a response? was he a threat to armed agents on the cliff, behind the fence. >> jose antonio's grandmother is an american citizens, living on the ordinary side of the fence in arizona. at a bedside shripe she prayers. >> translation: there needs to be justice. it seems to me a cold-blooded calculated crime. to me it's a crime with no justification because he wasn't doing anything. he was just walking. he wasn't doing anything.

>> almost a year and a half after the fatal shooting the border patrol at last formally responded to jose antonio's family. >> this is the claim of jose antonio's mother. their american attorney robert montiel showed me a letter he received dated march 149th: -- march 14th: >> and it's over, as far as they are concerned. >> robert montiel says the border patrol took 4 minutes from the time of the shooting to make this call to mexican authorities. >> let's listen to the call. >> robert montiel says the delay suggests indifference to the fact a mexican boy had been shot. >> if they are really worried about someone being hurt, you don't wait four minutes, because obviously the shooting had

stopped. >> jose antonio's mother araceli rodriguez says the letter from the border patrol is an outrage. >> translation: well i think they are mad. they are wrong. how can they not be to blame. it was an assassination. at no point did my son shoot at them. he didn't have a weapon. for me it was a murder. it needs to be paid for. justice has to be dealt with. people don't go around killing people. >> setting aside the unanswered questions of the jose antonio case, border patrol agents face soughts with rocks. this mem j went out to agents before -- memo went out to agents a week before jose antonio's shooting. it says: >> the memo instructs agents to

take cover and not shoot unless in danger. >> is shooting an appropriate response to rocks? despite the border patrol's letter to jose antonio's family, the department of justice and the fbi are investigating. local border patrol agents would not talk about the case or use of force policies. >> people feel like there's stonewalling, a lack of information and transparency. how does that affect the job? >> it doesn't affect it too much, because we don't have any control over the investigation. i explained that to people. overall, once the investigation is pending, we are out of it. you know, we cooperate with the investigative agency. as far as giving information to the public, we can't do that. >> surveillance cameras tower over the intersection where jose antonio was killed. whatever images caught that night have not been released. >> translation: show me the

video where my son throws rocks. with that they didn't do the right thing. i want to see the video, where my son hurts them. it's a pain inside me that will be there until there's justice, until i know who has killed my son and he has been jumed. om -- judged. only then will i think that all american border patrol are not bad guys. >> coming up tonight - al jazeera america with a new series called "borderland," tracking six diverse americans retracing the footsteps of three migrants who died trying to cross into the united states. tonight: >> at least 16 people are dead after a fire in central chile. more than 100,000 people have been evacuated from a port city. hundreds of homes have been destroyed. the blaze began yesterday in a forested area. it's the worst fire in the region since 1953, when 50 people were killed.

>> more than a decade of war has taken a toll on children in iraq. 5 million of them are orphans. not only have they lost their parents, but they miss out on an education. we have this report. >> this is no ordinary school. every child here is an orphan. in iraq you are an orphan if your father has been killed. in many cases both parent died as a result of violence, so they live with other relatives who can't afford to educate and look after them. the school is tucked away in a side street of baghdad, a neighbourhood that has borne much of the violence that the city has seen is since the american occupation in 2003. >> today, though, the children are grateful for the opportunity to be able to learn. >> translation: my father died in 2005. he was a taxi driver, shot by gunmen. my mother passed away two years

later. i live with grandparent, i offed to feel -- i used to feel alone at home. i come to stool and feel happy. >> this woman runs the school in three different shifts. 300 children are enrolled. for her it's a labour of love. she gets no help from the government and pays most of the expenses herself. >> i set the school up after my huss wand was killed -- husband was killed in sectarian violence in 2005. i realised so many children lost their parents and i needed to do something. with god's grace i opened the school in 2009 and run it by myself. i asked the government for help, but pleas fall on deaf ears. >> there's no accurate figures to tell how many residence and schools like this there are. there could be thousands of children attending united nations such as this.

for many, it's an indication that the government failed in providing the basic of services. >> this man runs a carte called childhood wishes for humanity. for her there's a long way to go before the needs of iraqi orphans are met. >> we are seeing more and more orphans every day. the security situation will see that more children will be left without families. we are under a tremendous amount of pressure, and without real help from the government, these children will be left without a future. >> for the orphans of baghdad schools like this are a vital life line. those running them fear they won't have the money to keep them open long term, and that these children and thousands like them will be forced to the streets. >> we have breaking news out of kansas. three are dead after two separate shootings at jewish related locations. overland park police say a

victim was killed in the parking lot of the jewish center in the greater kansas city and the other a jewish assistance living center. a picture is in custody. we'll follow the story and bring you more information as soon as we get it. >> only one month into the job and libya's interim prime minister resigned. he said threats from rebels was the reason for stepping down. since the toppling of muammar gaddafi, the government struggled to control the rebel brigades. the predecessor was fired by the libyan congress for failing to end a standoff between rebels who overtook oil reports. the gnc has not accepted the request. >> many offer traditional healing in nigeria over modern medicine. critics say it should be ruled out. but nigeria's government is trying to integrate traditional medicine into the health care

system. >> that man set broken bones for 20 years, using a traditional form of orthopaedic therapy. he has no medical degree, but took it up from his father who learnt it from his father. he's lanesed. one of -- licensed, one of thousands of medical practitioners recognised. >> if a bone is broken, form formation comes in, but in a tradition way, i tell you before six weeks he'll walk with it. >> patients say they find traditional healers more available, affordable and less invasive. >> my friend had a fracture like mine and went to a regular hospital. they amu tated his leg. we have more confidence in the traditional way. >> for many generations af the advent of modern science, traditional medicine appears to be doing as well as it has.

>> critics warn that it's not based on scientific research or evidence. some say it's difficult to draw the line between it and wich craft. >> but that's the impression the lagos alternative medicine board has been trying to change. >> it has been licensing. monitoring and training healers. including herbalist, bone setters and attendants. the 6-week course teaches anatomy, nutrition among other topics, and is a prerequisite to getting licence. the chairman of the board is a doctor and says it's about providing better health care. >> what we are doing now is trying to have a meeting between the conventional doctors and traditional healers so there can be a midway. we are talking about a country where we have 30 doctors to 200,000 patient. >> as part of the a push lagos is working on setting up a botanical center for herbalists

and scientists to capitalize on the country's medicinal plant, hoping they can offer home-grown solutions to endemic diseases such as malaria. they have been lobbying officials to build a hospital having them work said by side with fizz irnals. with the -- physicians. >>way with their practices here to stay, it's the natural thing to do. >> new orleans is known for music and festive atmosphere, but it made headlines with the number of college graduates moving there. more on the brain power in the big easy. >> known for its vibrant way of living, new orleans is fast becoming a brain power city, ranked number one, according to a new forbes study. despite the devastation of hurricane katrina, the big easy's population of college graduates grew by 20% fro 2007

to 2012, nearly double the national average. >> people were telling me "why are you going to new orleans, it was hit by a big storm?" paris is a ph.d. student at the university. she came to new orleans from iran. >> all the entrepreneurship here for my case, that i enjoy, that i can apply what you learn throughout the years of learning science. >> she met her colleague through the biomedical engineering program. hurricane katrina forced her away, but her ties brought her back. >> i enjoyed the program, the city and want to be part of the recovering. >> new orleans's population shrank. some saw a lost cause, and some saw an opportunity. it's attracting young people.

>> new orleans known for revelry, restaurants, unique culture, becoming home to tech companies from around the world. >> like paris based game loft and satellite company global star, who moved to the suburb of covington from silicon valley in 2010. >> louisiana is attracting megaprojects. some are tech. we spend a billion out of this office. >> the area benefits from a diversified economy says global star c.e.o. >> silicon valley was a challenging place to work. it was crowded. it was expensive. competing for the best talent was challenging as well. >> in new orleans, global star likes the prospect and playing field. >> we have a series of confluences allowing people to come, to stay and to thrive in different businesses that a few years ago didn't exist here. >> paris and elaine plan to stay

in the city after graduation. >> people want to visit new orleans. it's been a recent change that people want to stay. it's a positive outlook for the city. >> the ph.d. students have started their own business, and are optimistic about a sit that has a track record of overcoming extreme circumstances. >> still ahead on al jazeera america - climbtologists warn the time to switch to clean renewable energy is now. we show you how an experiment in wind power can help.

>> welcome back. the united nations panel is calling global warming a critical problem and is urging governments to act fast. harry smith has more. >> this was the third and final chapter in the panel's report on climate change. the message is clear. the world must cut its reliance on coal and oil and make a switch to renewable energy such as wind power. it is a result of intense negotiations. some call it a clash of interest. it offers reasons for hope, but also some staj warnings. >> the longer we delay, the higher would be the cost.

that is something which is clear. but despite that, the point i'm making is even now, the cost is not going to bring about a major difference. >> global surface temperatures are predicted to rise by 4.8 degrees celsius if no action is taken. the i.c.c. target is to keep it to 2%, beyond which dangerous impacts of the climate change will be felt. to achieve that carbon emissions will need to be cut by 2050. >> environmental campaigners lobbying the talks welcomed the report and urged world leaders to act on recommendations. this is the strong message of the report, there's hope. we have time to prevent

dangerous climate change, it will not cost money, it will save money. >> there are skeptics alarmed at the cost. tough negotiations will need to be reached on a global pact to reduce greenhouse gases bid enoffed next jeer. >> al jazeera spoke to a lead author about the report and asked about the economic effects of shifting to clean energy. >> i think that the messages that come out in the context of climate change mitigation have not changed dramatically from what we have heard in the past. that is true. there's a little more nuance. it is true that there will be cost to mitigation, that is true. one of the main results coming out of the report and in previous reports is that although there will be costs, there's nothing in the reports that indicates that mitigation will dramatically jeopardise economic growth. >> but there'll be costs. there certainly will. you need to use energy that is

more expensive currently. so there'll be effects to consumers. at the same time one has to realise that you are paying the cost in some sense to by something, and the thing you are buying is not going forward unabated. >> 2050, cuts of up to 60% - we are talking 36 years from now. if that does happen, what sort of changes will we be staving off. what state will the world be in by then? >> well, it's hard with climate change to know exactly what you are staving off. so what we generally do is say what would it take to hit particular concentrations of greenhouse gases giving us a good chance of not having temperature increase too much more and get the risk of harms coming from the increase. >> that's what you would be staving off. there's a number of estimates about how much we'd have to reduce by mid century, ranging for 50% reductions to closer to

75. that raises an issue of how much do we want to do now, versus in the long-term future. the more now, the less we have to do in the future. >> not only are you an expert in your field, i imagine you have a lot of conversations with your friends and the general republic. do you think people are coming around to the idea that no matter what others say it is. mann kind is ruining the planet. >> that issue is addressed in working group one. the concern i have is a dressing - what would it take to deal with climate change. that said, the results from working group one are unequivocal. climate change is happening, and it's pretty much unequivocally caused by human beings. it is becoming stronger and stronger. there's evidence of increasing harm from climate change. what we don't know is how much

harm we'll have if it continues to go up. in that context it's important to see it as a risk management problem. >> the u.n.'s climate change panel says advances in renewable energy will help countries shift to renewable energy. >> a power plant down under could set the standard in how energy is generated in remote communities around the world. andrew thomas explains. >> it's hardly a pumping metropolis. australia's king island between the mainland and tasmania has more cows than people. it's becoming a protio type for -- protofine for how island the world over can be powered. traditionally small communities rely tonne diesel generalities. but there are times it's powereded by wind energy, 2,000 customers and industrial customers. king island includes a high-end cheese-paying plant with powerful machinery.

>> we have run the island for 7.5 hours on wind energy, powering the whole island. total to date of 150 hours. >> ironically renewable energy targets have been reached by keeping diesel in the mix and wasting power deliberately. the traditional problem with window power is it's unreliable. not enough and the lights can go out. too much can be as bad. a surge can trip the system. the breakthrough is combining two innovations, a responsive generator that fires up and burns dossel when the power generated by the window and the sun, and a resistor, automatically tapping off power when overperforming renewables threaten to overwhelm the system. what we achieve with the enabling technology is evening out the variability in the renewable sources. the combination is what makes this a winner.
