Many and varied but humans are behind all of them. In uganda and new hydroelectric plants promises clean energy but will locals also benefit. First though we talk to scientists about the connection between Climate Change and Natural Disasters. Extreme weather events are growing ever more frequent Natural Disasters more destructive and deadly h one reignites the debate was it a freak of nature or a result of Climate Change and human activity. Recent hurricanes javi and maria killed over two hundred people in the u. S. In the caribbean and they cause nearly a trillion dollars worth of damage. From an outspoken Climate Change skeptic visited the disaster area. And he continues to rule out that human activity could have caused the catastrophe. But now theres a field of science which for the first time is able to estimate whether a Natural Disaster was likely due to human caused Climate Change or not but young german physicist at Britains Oxford University is studying hurrican harvie similar studies on the floods in louisiana last year produced clear results. In those studies we discovered that Climate Change had on average doubled the probability of this torrential rain occurring. And so it would be surprising if we got a totally different result in a neighboring state at the same time of the year just twelve months later calls came in so far the discussion about Natural Disasters and their possible link to Climate Change has been largely a political one its a high stakes debate involving powerful industries on the one hand and a risk to peoples lives on the other. Hand i thought that was in myself and in the fog in most cases its always been politicians who put forward and says in the debate that was what motivated us to say over the past five years weve developed these methods that allow us to make a qualified assessment and we need to publicize that. Its a whole field known as attribution science the date of recent extreme weather events as compared with long term climate models last winter for example the arctic saw record temperatures at the north pole they even rose above freezing in december. Thats more than twenty degrees celsius above normal. Whats new about autos work is that she can calculate how the weather would be in a World Without human induced Climate Change factors like greenhouse gases. When she compared that model for the arctic with the latest data from the heatwave there she was shocked by the results im on linux teammates of and if you look at extreme heat waves in summer they might be six degrees celsius above normal but not twenty degrees seventy two and logical terms it was a really really strain event extremis i guess moto has built a Computer Network to process the huge volume of data her climate models involve it allows her to calculate how much Climate Change has increased the probability of an extreme weather event like here in the arctic. And does this indian fire in this case all result. Showed that without Climate Change this kind of weather event would have been practically impossible this was the greatest increase in probability that weve seen to date on average human induced Climate Change made it three hundred times more probable a shine and. Conversely we need a link auto and her team can also prove a Natural Disaster was not a result of Climate Change for the record floods in southern germany in twenty thirteen for example the climate data showed no significant deviation in expected rainfall so there must have been other reasons for the floods buildings too close to rivers perhaps a lack of dredging a lack of flood plains in other words failure as a government level. But elsewhere in europe Climate Change has led to Natural Disasters the south of the continent has experienced repeated record heat waves in the last few years attribution Scientists Say thats because the probability of extreme temperatures has multiplied leading to more forest fires water shortages and drought worldwide habitable zone so shrinking which could have drastic knock on effects millions of people could potentially be forced from their homes. By hits of in with all the heat waves that we studied on various continents europe in summer is in fact one of the hot spots if you like for Climate Change not on the same level as the arctic but nevertheless its a place where you can see that Climate Change to significantly increase the probability of this kind of heat wave and thats of course an on offer and. The implications of this relatively new science could change our world three coastal communities in california have now filed a lawsuit against exxon mobil and other fossil fuel producers saying that rising sea levels of links to harmful emissions. And countries like the United States or germany might one day act. To be called to account for failing to achieve their environmental goals by promoting Climate Change. On the basis of evidence produced by attribution science. By twenty forty experts expect renewables to be supplying huge amounts of energy and the industry is also driving job growth the sector already employs nine point eight Million People three point six million of them in china alone. Thats a forty percent rise worldwide in the last five years. Global Energy Supplies already come from a range of sources by twenty forty power we harvest from sunlight is set to triple wind power will double. A coalition of forty eight developing nations acutely affected by Climate Change have pledged to become one hundred percent reliant on Climate Friendly energy by twenty fifty. Theres no question that Global Energy demand will rise its forecast to double by twenty forty not least because many people in now only gaining access to energy for the first time like in uganda. The seven only family make their way to their former home. They were forced to move away from here four years ago because their house was too close to the site of a new hydroelectric power plant. Feels good to be back here in the mountains this is where i was born. I was born here. And so one moment. We had all kinds of crops. Well call it. Coffee so we always have something to eat and we have money. The family farm three acres of land here at an altitude of fifteen hundred meters they can still use a small area of it so they return regularly for other families were also forced to move to make way for the new power plant. The concrete channel where the loop eally a river is to be redirected in the future is almost ready peter to mouli works as a project manager for a Danish Company called Frontier Energy it specializes in developing Renewable Energy projects in africa. Natural cause. You know especially the dry months but during the what month. It will be. Almost no difference. The channel is two kilometers long whats decisive for producing power is the force with which the water drives the turbines so from here the water will pass through steel pipes plunging two hundred sixty four meters down the mountain. The reason we need. To this point. Between this point. Is that. The entire project is set to cost sixty Million Dollars before the work even began a Feasibility Study was carried out to show whether the location was suitable that study alone cost six hundred thousand dollars the United NationsGreen Climate fund snow provides money for these kinds of initiatives in the past it was always difficult to get funding for feasibility studies. Because of the risk i mean. Youve got to youve got to get a group of people that you know ingenious that know what theyre doing and are able to look at a site from the very beginning and you know says you know what. These projects. You know that becomes very easy. To turbines are due to arrive soon the hydroelectric power plant is designed to produce over five megawatts of electricity one running at capacity thats enough for thirty seven and a half thousand households the plant is supposed to provide electricity to this remote region on the border to the democratic republic of congo but the local residents arent yet linked to the power grid so for the time being they wont benefit. What we tell them that will. Tell them that i think. You can be and not have the right you know because to do anything with them but what you can do. It to intercede with the saudi. Government or the media to bring about the i think. Just enough but if you want them to know that thats what. This still will be used to make a wedding cake its all part of a cookery course for local women. Then you can use your hands so you need to wash your hands remove all the balance in your hands. Two hundred thirty eight families have been affected by work on the power plant so the company has to give back to the community in other ways really ties in charge of the course she has also set up lessons in beekeeping and arable farming if you have them i think like baking they will produce a product and send it off they would be able to sell them so. Basics thinking they dont have to us for the men everything. Back to the seven only family. For the past eight months theyve been living in their new home on the plains fifteen kilometers from their old one. The first time i came here i was very happy with our new home but gradually we realised that our new life was very hard we hardly had anything to eat even though we had a nice home. From january to june this year there was a drought that meant the family was unable to harvest anything the house only came with a small plot of land and the banana plants are still too young to bear fruit. If they didnt have the remainder of their farmland up in the mountains the family would be even worse off once a week employees from front to your energy visit them four of the children are no longer going to school because the family cant afford to pay the fees. To look into the. Issue being far and. You know just go back and you know just look at what led us or what led them to choose that place. And then you know find some way of. Bringing to them a piece of land that is closer to. The father and one of his sons are currently working as day laborers to help the families scrape by the Hydroelectric Power Company still has their work cut out for them. Kids for climate have plenty to do to vision and are committed to protecting the environment and slowing the pace of Climate Change. Eleven year old giana writer is organizing a close what party at her school its the second time shes done it. I think because its important that we all do something to reduce the level of consumerism that we take a stand against so much new stuff being bought if you buy less because you swap more theres less need to grow so much cotton which in turn means that fewer pesticides are released into the environment that. Environmental protection is important in lessons to yana believes it will be one of the biggest issues for her generation. And. If you are many you can bring about real changes and we have to tell adults what to do because this is our future and at some point they wont be alive anymore then well be the adults so we have to do something for our future. I read a quote by bertold brushed change the world it needs it that really stayed with me because its so important its about our future. And. Fifteen year old. Lives in a small town in south west germany where hes surrounded by nature. And his team set up protest rallies seeking to persuade politicians to do more to protect the environment. To the north it would be even more fun if theyd actually listen to our arguments and responded. But all in all of course it is fun for the team to be out there getting involved in politics. Them and yet somebody. Twenty years ago for example there werent any marbled fish larry butterflies here yet and now i see them all the time in the summer. So its clear that Climate Change is having an effect and that. Im a uploads have pictures to an online database its a place for people to document the flora and fauna in the state shes already uploaded about seven hundred entries each discovery is flagged on the map. Im a protection is fun because it gives me something in return i feel like im doing something worthwhile with my time i really enjoy it but i think. Doctors in new delhi have declared a Public Health emergency the problem poor air quality and its not the first time cold air forces the small down into the city so pollution levels of particularly bad in winter the air is so toxic right now that most schools have been closed the Indian Government is enforcing driving restrictions to try to get the situation back under control in twenty fourteen the World Health Organization named to the city the worlds most heavily polluted capital. Every year over a Million People die prematurely in india because of toxic particles in the air thats according to a un study in new delhi theres no escaping the pollution. More. Than i. Hope. Judge no pundit is seventeen years old shes very concerned about the air pollution in her home city. So by leaving them to the doctor and. I have this. Car sales across india reached record levels this past year the capital alone has ten million registered vehicles. Many have diesel engines which are particularly toxic last Year Emissions in new delhi when he thirty times higher than World Health Organization limits indias former environment minister says for years the governments main focus has been on Economic Growth whatever the cost i didnt mean you know people want jobs people want brodrick to be one factory was there when those are the risible signs of progress right usually seem to be you know ok weve got a little you know thats something that we need to do. Or really had to do in order to industrialize and organize but i think thats probably going as increases as. Civic movements and i gather a p s i think a lot of governments will have to be sensitive to these issues. Citizens initiatives like help delhi green being the pressure they want the government to tackle the problem after ratifying the Paris Climate Accord last year the Indian Government is taking some steps its drawn up plans to overhaul or shut down some of the countrys coal fired power plants. The Agricultural Sector is also coming under pressure every year farmers around the capital burn off the stubble left from harvesting rice to make space for the winter crop of wheat the thick plumes of smoke waft into the city that alone accounts for one quarter of delhis air pollution surrender punj owner has been farming his fields in the district of party island for fifteen years but these days he does things differently. To burn the stubble every year but it was bad for the environment now the governments restricted this practice so some of us are seeking a solution we want to protect the environment. With em. His solution is to use a mulcher and a rotovator which he bought together with another farmer to cut down the straw or left after harvesting then he can just leave it lying in the field that helps protect the winter seed and eventually to decompose it but many farmers are still burning their fields turn it if it involves buying equipment which few can afford the government now office subsidies for machines that can help keep farmers from burning their fields local n. G. O. S are seeking to persuade the farmers to sign up but not everyones convinced. Takes ages to apply for the subsidies and even then there are no guarantees youll get the money. Theres a lack of awareness. We have to work hard to persuade farmers of the advantages. Thats the biggest challenge we have are trying to point out that its for their benefit. Progress is being made but its slow india has set some on bishops goals by twenty thirty all public transport is supposed to be fully electric along with many private Passenger Vehicles the government is also looking to promote Renewable Energies to meet the countrys huge power any. Nuclear costs not going up. By. Plummeting and i think. That works to our advantage that gets reflected in the commitment that we were made by producer do we were forty percent or five liters of you from now on fossil fuels are all green thats an reasonable target because already we are knocking on thirty percent but judging a pundit feels twenty thirty is too long to wait shes decided to start protecting the environment herself. So i have no firsthand experience what children go through when theyre subjected to dust particles why dont i begin initiative to do something for the environment. Together with two friends shes developed and filter they entered a competition organized by the un in tandem with Indian Industry in schools and won an award for their invention. And it does collect inside the bags it forms a pick bad idea which for that improves the efficiency of the penetration. I believe its up to the
