The world has changed weather is getting more extreme. Today be a struggling when the talking of people in the mood in dominions than in talking up of people in the billions of drought floods hurricanes best areas are being devastated by environmental catastrophe how many people will be forced to leave their homes by the mid century not due to conflict in war but due to Climate Change we appear to be on the path to a. Troubling future. From mr hill region to Southeast Asia from the pacific to the caribbean some people are fleeing rising waters others drought. The worlds population began to soar about 200 years ago soon it will top 10000000000. 00 Greenhouse Gases are rising apace the resulting warming of the earths atmosphere is wreaking havoc on the climate humankind which is responsible for this warming is becoming its victim more and more people are forced to leave their homes. Inequality is being exacerbated by Climate Change wealthy industrialized nations are polluting our air while the main victims live in the global south for example indonesia. Pontypool hadia which means happy beach lies on the indian ocean due to rising seas and heavy rainfall the village is sinking into the sea. The flooding continues even now during dry season. The local Primary School is down and smells of rot parents say conditions are intolerable and more than half the children have been taken out of school. Teachers in primary grades. He attended the school herself and is determined to persevered. His classroom flooded for the 1st time in 2013. But none that conditions here are very very difficult for us we often have to send the Children Home when the classrooms flood the children sit with their legs in water. Regular instruction has become impossible the children are falling behind within the next 5 or 6 years rahmatullah believes the school will be submerged. It will be abandoned along with the village. What will it look like here 3 decades from now in the year 2050. Them there will be the most extreme conditions. For what with our 17000 islands of coast and that will be if not by the sea so life will not be the same and thats a lot of illness it will be plagues and the. Growth of the whole world will be disturbed by horizontal strife. One against the other because fighting for food water maybe erasure that very sad picture 2050. For the for the Indonesian Special envoy the catastrophic impact of unchecked Climate Change is the biggest challenge facing humankind today 10 years ago the topic was barely on the radar. Jakarta the capital of indonesia with some 10000000 residents its the largest city in Southeast Asia around 30000000 people live in the metropolitan area making it the 2nd largest urban conglomeration in the world. In the fish markets are located in North Jakarta the scent of the ocean lies in the air mixing with the odors of the city. Just a few kilometers from the city center the problems confronting this tropical metropolis become apparent residents struggle with small heat heavy traffic pollution population density and poor hygenic conditions and with increasing frequency flooding. The slum district of data is located near the airport its 5000 residents used to live near the sea but these days it almost looks like they live in it. Eco zoom are no has lived in since the 1970 s. He and his neighbors have watched the rising sea level with concern. At least once a mom says the flooding reaches his knees. Sometimes the water remains 2 days sometimes a week you know. It floated here for the 1st time around the year 2000. First it was just a few centimeters. Since 2010 the flooding has been getting higher and higher but its never been as bad as it is now. And yet while english at. In jakarta the districts closest to the coast face the biggest problems poor neighborhoods like that up will be among the 1st to meet complete relocation. Of the slums most at risk are situated along a wide corridor that snakes through the city says urban planner Marco Cousteau my view jaya. Floods all. The coastal areas and the flag. Was so ops teams in the city center of their god of a view from my wolf is. The job is director of the root jack center for urban studies which searches for solutions for climate related problems right now their focus is the depletion of groundwater from the area the declining water table has even more serious consequences than rising sea levels. Its causing the ground to sink and large parts of the city with it it may get in most of the other because on the big dark the sea level rises at between 4 to 6 millimeters when your butt was used dylon to. Subsiding by. Tree to 20 sente metres. In february 2013 nearly half of jakarta was underwater. Scenes like this are likely to become increasingly common. Ocean levels continue to rise the land is collapsing and heavy rains are becoming more frequent. About one 3rd of jakarta is currently below sea Level Environmental problems are causing a growing number of people to flee the city but most want to remain or have no other choice in an effort to protect the capital the government has begun building a seawall. But only 6 of the plan 50 kilometers have been built. And even their water is finding its way through its becoming clear that ever. Thing located directly on the water will one day fall victim to it like this mosque. The bad thing is actually most of the poor neighborhoods would be flooded because the rich neighborhood effort raised them so you know but exactly because they have raised their good all so the water column. Will actually flow into the surrounding poor neighborhoods. Poor districts located along one of jakartas 13 rivers often stay submerged for weeks when the floodwaters rise. Areas near the chilly one river are most at risk like this low income district by the chilly one tributary tom call situated just 400 meters from the ocean the drivers housekeepers fishermen construction workers and such that live here all face Climate Change related risks. This estimates are that 65 percent of the patients of it will be directly. Affected by sed me that mr people of 65 percent of the 300000000 philip 1000000 this 170000000 people in. An island nation and 6007 that. This would be destroyed if they came up with figures of 14000000 for 0000000000 because they are the people and those are the. Effects of landslides. Along 40000000 people. And then those involved may have to leave their homes. Elite. Indonesia is prone to a variety of natural disasters from cyclons to mudslides flooding to drought but there is one place that has that risk of all of these the island of java. And its here that one of the worlds most densely Populated Areas is located jakarta. The citys infamous traffic jams last almost until midnight only to resume again at dawn. More than 3500000 people commute into the city every day. And. Just 100 kilometers southeast the bustle of jakarta is a distant memory. Shown your district is situated at the foot of 2 and active volcanoes. Its one of javas most fertile farming regions. The rice vegetables and fruit grown here help feed the countrys capital the village of surrounding is accessible only by motorbike or on foot. To do wrong he runs a small Coffee Plantation here like his father and grandfather he is a farmer. Coffee used to be a safe choice it fetched a better price than vegetables and was hardier than rice. But thats changing. When i was younger all farmers would plant during the rainy season so january february and march. And then everyone would harvest during dry season. But now my colleagues and i are desperate. Because its often dry in the rainy season and in the dry season it rains. But we are paying the price for Climate Change our harvests have dropped massively by about 60 percent. Nearly half of local farmers have given up theyve moved to other parts of indonesia or left the country altogether some have become construction workers in saudi arabia but due to ronnie doesnt want to join them. So. I cant imagine doing anything else. But i will stay here as long as possible but im a farmer thats who i am. Im going to try to somehow it down to Climate Change if its too dry when its time to plant for example ill just wait. These mountainous regions dont just supply food to the cities and their forests also help store rainwater but extreme weather conditions are growing increasingly common here. And still forests are falling victim to logging leaving rainwater to flow unhindered into the valley sometimes the water sweeps away everything in its path. Thanks. Mudslides have had fatal consequences these images state some 201728. Special climate envoy veto law says that by mid century Climate Change will have forced 40000000 people to flee their homes in indonesia alone farmers who can no longer till their fields slum dwellers whose 10 roof tugs have sunk into the sea. Most experts agree that its the worlds coldest regions that have become the cauldron for Climate Change these are the arctic the antarctic alaska and much of the permafrost of russia. Z. Im all for trained as a mathematician. But his father sergei is lifelong commitment inspired nikita to change course. Now. Now like his father he has dedicated his life to preserving russias permafrost. Hes come to the collene a river in northeastern siberia an 8 hour flight from moscow to gather evidence that the promise frost is vanishing. The ground has warmed up to 3 degrees celsius causing the top layer of the ice to melt one side effect is that more and more rare fossils are surfacing. For paleontologists this would be a treasure trove. A field of riches from the distant pleistocene epoch. So think of that moment. Not the biggest one but every stage. 20 so here was in the present because the snow here was huge and never as quick a moment and there were 4000 years and all there was here on the square kilometer now were around 600. So every once in a while there. All along the kalima soil is a road sliding into the river as a consequence of the melting permafrost. Nikitas him off because plants like these zombies because the soil in which they are growing was barren for 40000 years. This vegetation will also soon end up in the river the big. Changes taking place here could soon be a reality across wide expanses of russia. And it could also have a dramatic impact on the Global Climate and mass migration of peoples for there is an immense amount of biomass still trapped within the palm of frost. If that trap c o 2 in methane were to be released into the atmosphere the pace of Climate Change would increase dramatically. So theres a group of grasses which grew here maybe i dont put a 1000 years ago and they prove that this is a huge storage of carbon and they call this little roots and put them on the one side of the balance and on the other side of the balance put all the above ground vegetation of the point so basically all the trees and shrubs of the burnet you will see that these tiny little sweet more and the better for us will start to be great everywhere all these we will become what we were before microbes to eat and they were very soon gotten to Greenhouse Gases. Thats ice pure ice out there and you see well this ice is melting the water is mixing with this soil and creating this month full of children down the thought and legal issues have been very rapidly here so its a combination of both a lot of carbon and there was a fight and thats that give you a very rapid carbon but for every problem that will be kept in it with the Global Warming worldwide which they think will be a problem before right. So you could do its and see if its going to be bad somewhere it didnt vary but so if there is a week to stop that from happening like we need to apply that because if not you know. You can write any apocalyptic night if you want and probably most of them will come true. Its breakfast time and nikitas the most guest house. Interest in permafrost has soared over the past decade so now the guest rooms here at the station are usually booked year round with researchers from all over the world. This is a group from Oxford University here to study the transformation is currently underway in what used to be frozen earth. During the soviet era this enormous satellite used to broadcast Television Programming from moscow. This ng laughs turned the station into a home base for scientists from around the world. Well though the data that has been collected in siberia and across russias far east are alarming normally the vegetation binds Greenhouse Gases in the summer and only releases very small amounts back into the atmosphere in winter. So out here you can see that. Here one of which is. What got us. But for the past few years the permafrost thats stalling more and more in the summer is releasing ever increasing amounts of methane and c o 2 during the winter. 2 2 some of the finest is acting as a focus area as a friend is a moderate brake on Climate Change so if about 40 percent of the Carbon Dioxide we emit is being absorbed by the biosphere and thats acting to slow down Climate Change if i wasnt happening Climate Change of even faster than that it is one of the big concerns we have as a system scientists is understanding how long well the biosphere keep acting as a brake and is there a danger that at some time in the future or if this break will turn into the accelerate. Scientists from all over are turning their attention to the permafrost and its potential impact on Climate Change. This group of researchers from prague is being hosted by the institute of applied ecology of the north and the republic of soka. The researchers have just returned from a crater that is carved into the permafrost. The soil samples are a gift to the institute. In return the researchers hope to obtain permission to exhibit some of their spectacular finds in a museum at home remains of a mammoth in the mummified remains of an extinct horse from the pleistocene epoch you. Know. Here. The when the if they were going to go. With them in the crater and which the fossilized remains were found was named the bottom gaika crater but locals call it the gateway to the underworld. Its easy to see why. In the 1960 s. A small section of forest was cleared to make way for a new road. The problem frost originally beneath the trees began eroding. That 1st the hole was just a few meters deep. The stupid on average the make a crater is between 40 and 60 meters deep and in some places its 100 meters deep its 1. 5 kilometers long and about one kilometer wide right now but its hard to determine exactly how wide it is because its expanding so quickly because these kinds of catastrophic events could become increasingly common and not just in residential areas but anywhere in the wilderness wherever there are pipelines and natural gas facilities our entire infrastructure could be impacted. As opposed to. Most of the cities in siberia and in russias far east could be affected about 25000000 people in all. How big would the impact be if all the worlds permafrost were to melt so far there isnt enough cross Regional Research to answer that but there are findings regarding the polar region from a global terrestrial network for permafrost in 1906 the problem melted to a depth of 45 centimeters in the summer by 2017 it melted to a depth of 87 centimeters a nearly 100 percent increase over just 20 years. This poses a danger to both people and infrastructure. Natural gas and Oil Pipelines are particularly affected. Greenpeace has estimated that leaks in pipelines caused by falling soil are leading to about one percent of oil being lost that oil some 5000000. 00 tons of it each year seeps into the ground. The residents of the arctic city of chere city in the far northeast of russia are bare. And witness to this rapid transformation. Temperatures are rising and exorbitant. Asphalt on the streets is beginning to buckle. And several buildings are showing signs that the solid ground on which they once stood has begun to sink. The city of chere ski on the kalina river is also home to nikita zeem off. Even though temperatures drop here to minus 60 degrees celsius in the winter the erosion of the permafrost soil appears unstoppable. This is especially apparent at the former Water Treatment plant. Like all the buildings here it stands on pillars. The earth began to sink here just 2 years ago now the crater is already 10 meters deep. Into the ground is going where there are so what i was here a week ago there with them those 2 points with you in the air and now we came they already could go up down and there is a huge nish going underneath there for the way this in this ice has been there all that and eventually all that full fuel coops so this for us its going to go in and its you know centimeters a day maybe tens of something in the same day when the whole day of the week of cities in the powerful and now with climate getting warm up there for them both are getting warmer and we begin to bake and it off like that so all the infrastructure in the next few decades will probably be caught up. Elsewhere the heat of the sun is relentless this is cameroon and central africa. Here in the stream bed of the mile below river signs of despair are everywhere. In. The north of cameroon receives 2 months of rainfall a year at most in august and september during the rest of the year people must walk far to find water or dig deep. Older people who live here say that water used to flow abundantly through the mile below river into the low gone river and eventually discharging into lake chad. But those days are gone. They do are cut up our works for the Current Charity organization in the region his job is to ward off the looming humanitarian catastrophes. Access to Drinking Water is an enormous problem for people and animals here in the far north of cameroon. Often visits village
