Podcast Leave us in 4.5 billion years. Our world has gone through many natural changes. That has now changed again, but this time we have contributed to these changes ourselves. If we continue like this, the world will heat up. Our children and grandchildren will face extreme and potentially catastrophic changes that could be drained and burned by the vast Amazon rainforest, and the oceans could be changed by the destruction of much of the life they currently contain. The Arctic can change, its ice can melt, and its most famous animals will be gone forever. The rising tide can damage the lives of millions of people. Many of our coastal cities have been flooded. Drowned, we still have time. There are ways to reduce these changes. If we all choose to accept them now, but if we miss the opportunity, our future could be the green of life on earth, then the next few years will be decisive.
Most scientists now agree that our planet is warming and that humans are at least partially responsible for it. So the question is: what will happen and what can we do? We know that there has been more carbon dioxide in the atmosphere for the past 650,000 years than ever before. Carbon dioxide is a greenhouse gas, invisible and tasteless. It's heating up on our planet like a blanket, we add 25 billion every year, and I spit on them like fear.
When the blanket gets thicker. The earth is warming, this is a forecast for 2006. It can be a forecast for 2050. Yes, you won't hear a sound in 44 years that can become another powerful feeling. Now that the temperature is at the dawn of the 21st century, the records of 38 degrees in London and 33 degrees in Scotland are better suited for the stadium. Well, for many fairly warm nights when the temperature off London is no less than 6 degrees, it will be the next day. The weather will be dry again tomorrow and the high temperatures will continue. Without alleviating the drought in south east England, this isn't good news for The Gardener's
. There is a possibility of absorbing heat. I still remember the summer of 2003. But that summer had a dark side, tens of thousands of Europeans died in the scorching heat. Although such summers are still rare. It is possible that such a brandy would appear every two years by the middle of this century and be so popular until the end of this century. The summer of 2003 will be very cold. It sounds terrible. Ah great?
Everyone wants to know what will happen to our climate in the future, be it a heat wave or a panch tide. Scientists can only show us a number of possibilities and say that our world will warm up between four and five hours in the temperature range in the next century. The consequences of global warming will be severe to catastrophic. Any type of weather forecast is not easy, but the Hadley Center Weather Bureau meteorologists have one particularly difficult problem. They looked at what our climate would be like. A hundred years later, we willthrough a process called climate modeling
discuss four degrees, where the climate model is essentially derived from the weather forecasting model. Depending on the many possibilities on which our actions on climate change depend, humans have to decide which of these paths to take. Modelers use one of the most powerful supercomputers in Europe and reduce 10 billion calculations per second. It's like a flight simulator for the future climate. You can ask him questions. For example, what if our CO2 emissions double or how hot it gets
? All in all, what lies ahead seems like an odd course, and there are many customer models around the world. Now I agree, for example, that greenhouse gases will heat up the system, and there is hardly a model in the crowd, let alone climate change. Everyone said it was actually between 2 and 6 degrees. In the eyes of many people, climate change is already 2 degrees dangerous. A warming of up to six degrees in a hundred years will heat up so quickly. It's hard to see that it's not doing irreparable damage to things.
For easier viewing. What is in store for us? Pierre, Cox. He invited me to see this film. It is a vision of how and where the world will warm up if we continue on this path. Our current forecast shows that the average temperature in southern England will rise by 2 degrees by 2100. Most people think it's good, but it won't be bad. I mean, maybe the south of France came to the south of England like this, and it would be warmer there. There is no doubt that the weather is getting warmer, but climate change in the south of England is obviously multi-faceted and we are particularly concerned about the drought. That way someone gets very hot. The paintings. Then again, people will think it's okay. But also expect ever changing extreme events,
more storms and floods. The problem isn't just warming up. Last summer was relatively dry. But when you see the rain it is very strong. Likewise, local lightning can occur in almost any location during the day and it becomes a fairly salty day in Scotland due to the flooding caused by these torrential rains. The archives office assumes that this will be the case in the future. If it rains it will flood somewhere in the UK, especially in winter. Our forecast could increase the likelihood of flooding by a factor of five. In another corner there was a devastating heavy flood that destroyed the house and left several walls in two hours when the tide flooded the old part of the village near the port. The absence of Mirsada means being utterly
shocked by the destruction beneath me. Filled with chewing gum. The Royal Air Force's Thompson was one of the rescue teams who saved hundreds of people when the castle was flooded in 2004. My first impression is how many people will survive if our climate changes. Extreme events like Boss Castle are more likely, and emergency services are already preparing for them. Well, the gearbox is something that we have to deal with. So when we observe changes in the weather, weto
need to be prepared for babies to be overwhelmed by dangerous situations like flooding and readyresume emergency services. . Another valley with great privileges works in such a way that it can really happen anytime, anywhere. We always build houses and roads according to the weather, but the constant efficiency of our construction is important. We can no longer take this for granted. This
Essex dam was built to protect the houses behind it from tides and storms, and it works well. The climate is changing, however, and there is no guarantee that such protection will exist in the future. The house that stands behind this wall, like millions of houses around the world, is perilously close to sea level. There are many such places along the Gulf Coast of the United States and the Haddiq pops up every year. In August 2005, many New Orleans citizens were battling Hurricane Katrina, which was just one more person to feel safe with the extended and reinforced levers built since the 18th century.
Oh no i'm fine But yeah, it sounds more dangerous than a storm so you'll be fine. However, Hurricane Katrina caused a storm in New Orleans that was higher than the tsunami in Asia. The dam interrupted the flooding and 80% of the city drowned, killing more than a thousand people. You get a house, that's a situation. How do you connect? But Greg Holland thinks we need to strengthen ourselves. Our defense, now we are preparing for the future.
The industrial sewer is obviously broken here, you just imagine a huge wall of water rushing in all the way and taking everything away. I mean, nobody in the area died or was in very bad shape. Imagine what kind of an accident it would take on the highway to make this type of damage truly incredible. What is worrying is that all of the damage we've seen here was caused by Hurricane Katrina, which wasn't a particularly powerful hurricane. The destruction we see around us tells me the future is here
and we really need to act now. On the other side of the world, too, many Australians will have to find new ways to fight old enemies. It has nothing to do with rising sea levels, it's a fire. Concerned about climate change, what seems to be happening? We don't know what it is. Fires are part of the Australian phenomenon that has been around for millions of years. Weather conditions and unstable weather are changing. It really makes us afraid of the power and frequency of fires.
Russell Reese has been putting out fires in Victoria for 30 years, but after a record-breaking year he's in the future. This requires a new approach. We built it. Traditionally, the fire brigade is based on a mature belief and theory of fire behavior. Fire is more difficult to control. They become more unpredictable and our usual fire measurement methods and behaviors are challenged. If the situation changes, think about it. We only consider factors of consideration, our resources, our tactics and our strategy. We do this so that we can defend ourselves and protect ourselves from such changes.future
Forest fires could even break out in the UK in the. By the middle of this century it will be a major risk, and the risk of grassland and forest fires will increase because it is. After the dry weather and heat, the weather is bone dry, there is no sign of this subsiding and there is talk of heat and potential forest. How reliable is this forecast? It depends on how you look. I think if we look at the next few decades, these patterns will coincide with the warming we might see. We don't have much of a choice of
what will happen in the next 25 years as it is largely due to the promises we made in the past that the UK is warming 122 degrees. For example, it's almost inevitable. Whether we end up with four, five, or six, we still have a lot of control. How climate change will develop in the next few years depends on how we think, how we think soberly. We know that human activity is large-scale. Massive deforestation, the almost universal use of fossil fuels is changing the climate, but can
I do something on my own? Can that have any effect? Well, more than half of the carbon dioxide produced by humans comes from our family activities. Meet the carbon there. A fictional family that lives somewhere in the western world. They live in ordinary suburban houses outside the ordinary cities. Coppini depends on the average performance. They come from an energy network that is mainly supplied with coal, oil and natural gas. Carbon isn't bad,
but as westerners, you have one of the most energy-intensive lifestyles in the world. Dad pig. Mr. Carbon's car, like most people, emits a lot of carbon dioxide. The Carbon family has two cars each year
that emit 20 tons of carbon dioxide into the atmosphere. Cars are 10 tons, but not just cars. Operating a single-family home made of carbon fiber with all the comforts consumes almost as much energy as your vehicles. Every function or entertainment device has an impact. At the
power plant. The scientist is scared. At this rate, these daily emissions could push our climate to critical point in the 1950s, and the changes are no longer gradual, but sudden and extreme. In the Arctic, thousands of kilometers from the Carbon House, the ice is already melting. The loss of the sea ice really shocked us. It's one of the most widespread changes out there and the most widespread. We saw it in the arctic system and it really opened our eyes.
If we compare the amount of arctic sea ice. Compared to what we have today, we had it in 1979. In just 20 years we've lost about twice the size of Texas. It's a very alarming rate of change that we've seen. Texas is twice the size of Great Britain and more than five times the size of Great Britain. And it's not just the North Pole in 2002. On the other side of the world, Antarctica, the entire Larsen Ice Shelf, B. When white ice replaces the dark ocean, it is "the beginning of a sudden and dramatic change in tilt" . Pointheats
where itup strongly. This ice cap is so bright and white. It will reflect a lot of solar energy that will fall on it in space, but when we start warming the North Pole and that ice sheet starts to melt. What will we do when we start uncovering dark ministries? Dark ocean and dark ocean absorb much more solar energy than white. I stress that the Arctic is getting warmer, which means that the snow and ice caps are melting and getting warmer. Some people predict that the Arctic could be completely ice-free by the summer before 2070 and all of these dark oceans will warm the land. And more.
In fact, we are doing a big worldwide experiment and we have to accept the results of that experiment. I don't want people to react to that. Of course there will be big problems in nature. In fact, we've spent a century keeping the state of pace, it's here, it's one of the biggest worries, it's happening. Now of course, right? I mean, Mediterranean species come to England. Yeah, but the people on top of them have nowhere to go.
that's right. Of course, this also applies to species that migrate to the mountains. So, they expect to see results first. You think there is already evidence that this happened to Captain Mountain. I installed an ever changing species, and eventually a great number of plants and animals. He'll go away. It is a problem. Yes, the earth will change. I think all of this will happen. Now the earth will change. The question is, can we give it a soft landing? Nobody knows exactly what effects global warming will have on the flora and fauna of the world:
some speculate that by the end of this century, with fundamental changes in the environment, up to half of the world's species could be threatened with extinction. Animals with special lifestyles. Like the south, the American eyebear is just one of hundreds of endangered mountain species that have warmed the Andes. South Africa is expected to be one of the hardest hit regions. Yes. In other places, when the habitat changes, animals are forced to migrate on a large scale.
There will certainly be many sacrifices. The carbon house is not threatened with extinction. On the contrary, there is often food here. By the time he got to her kitchen, he had traveled to all continents. Transporting this type of food is responsible for more than a tenth of greenhouse gas emissions and more.
Waste carbon produces more carbon dioxide. The Energon landfill is warming as it decomposes and releases greenhouse gases into the air. From the beginning, the carbon dioxide layer around the earth has become thicker and thicker and has brought the planetary ecosystem to a point where there is no going back. Let's look at Amazon. Yes. What happens now, we believe that if these predictions come true by the middle of this century,
carbon dioxide will continue to rise. As a result of climate change, forests could actually begin to die, which would be completely catastrophic. The Amazon rainforest is already suffering, the devastating effects of the 2005 drought have dried up rivers, and scientists are like bloody warts. In doing so, they discovered that the forest was exposed to threats previously unimaginable. Decades and decades. Then, assuming these forces did not ignite, some researchers began to find charcoal underground. The deep forests of the Venezuelan Amazon. We must warn the government that there is
a disaster of ... The first answer is no, these forces cannot help but burn. But more and more, with this type of drought, more and more serious. We have seen these forests marginalized. Netstat has found evidence that the world's largest forest has a devastating future. For me, this is one of Amazon's most terrifying visions of the future. It is a forest shrub. It's very ugly. It burns all the time, is flammable, and of little value to local residents, but it
doesn't just affect local residents. If all of the most ridiculous things are destroyed, the 15 year old global emissions of carbon stored in tree tissue will be released into the atmosphere, further exacerbating warming. So this is one of the turning points in the climate system where you can hit unsustainable levels of carbon dioxide in the forest and at this foot. So that means you get more carbon dioxide and more climate change. This is a turning point, and
not only are we going to lose the most diverse ecosystem on earth. We could also lose the earth's irreplaceable cooling mechanism. We almost think of it as the most perfect air conditioner in the world. This means that it absorbs all sunlight and converts about half of the sunlight into water vapor. It's true. It cools the planet and is big enough to affect the size of the entire planet. Amazon may not be there. It is terrible for me
. Mr. Carbon dreams of a vacation in the rainforest. Today, however, he was on a business trip, but when he flew it was contributing to the fastest growing source of carbon dioxide. Even if fuel tanks are equipped with more efficient engines, emissions from aircraft around the world will continue to double in the next 25 years.
Carbon produces up to 45 tons of carbon dioxide annually. In developed cities. Millions of simple families will produce a lot of carbon dioxide if they just take care of their daily lives. The western world produces most of the greenhouse gases. But this will change. And the lady. Sunbathing.
These are fictional couples who currently live in ordinary Chinese suburbs and only use 1/7 of the household's CO2 energy. But the life of the city dwellers is changing rapidly. With 1.3 billion Chinese, they are moving towards a more energy-intensive lifestyle. During the recent market development, Mr. Tan got a new job and owned an apartment and the most modern energy-consuming appliances that have contributed to their economic prosperity. China has a great source of cheap energy.
Oh, it's the most highly carbonated source of energy we have today. China plans to build a large coal-fired power plant every week for the next seven years. 5. China is likely to become a global producer of greenhouse gases in the next 20 years.
This is an explosive growth in global energy consumption. We will double the number of recognitions by 2050. Not all of the carbon dioxide we produce will stay in the atmosphere forever. The oceans take it in all the time. When the concentration in the atmosphere increases. As a result, the ocean absorbs more of it, which can lead to another of these twists on the sea. Biologists like Steve Widcombe are beginning to worry about this effect. This means that carbon dioxide does not remain in the atmosphere.
Almost half is dissolved in the ocean. As a result, the surface of our ocean is more acidic. When carbon dioxide is dissolved in water, the acidity increases. It can be deadly to many of today's secret treasures. Take a look below. Here we have a very common animal on our shores, beautiful animals. Here is a piece of music. the third. This poor creature will be affected in two ways. First, the acidity of the ocean dissolves its shell and, second, the chemicalswith
it was builtmissing. Here we have another animal closely related to sea urchins. It is a thorny starfish and can affect animals such as starfish. In the ocean, hedgehogs can be difficult for animals to form bones, and they will also have difficulty eating and reproducing. It should have a starting point, a threat not just to individual species but to the entire food chain. Plankton are floating plants and animals. Some are so small but so numerous that they can be identified by the acidification of the universe during flowering, which can destroy plankton that deceives various fish. It is, in turn,
the food of increasingly large marine life. It could even affect the largest mammals in the world. The effects of acidification extend far beyond the ocean. Millions of people around the world depend on marine life for their survival. I mean, it's almost like a warning. This will happen if we don't correct ourselves as a species. We have many choices, and people have many choices about where we will finish by the end of this century, because that much depends on the amount of carbon dioxide we emit by
the end of this century. So how do you reduce CO2 emissions? Professor, some of the greatest scientists in the world believe that there is an urgent need to find a solution. Steve Baccarat is one of them. I have faced various environmental issues in my life and you tend not to worry too much. The problem of global warming, on the other hand, is paying more and more attention to experts and people who deal with it. As time goes on, this has become the most pressing environmental problem for me, and it is the problem that we need to solve
now. We every year the amount of emissions into the atmosphere is the same as in 50 years. To solve the global warming problem and prevent the atmosphere from doubling, we will be using more than double the air and will need to freeze emissions at current levels. Level in the next 50 years. Because there is no single way to solve the global warming problem. Picanha divides it into seven equal parts. Then he came up with a different approach. Each slice can be saved individually until we reach the final goal of stopping. I'm watching the rise in CO2 emissions closely; I believe this generation will save it. If we form a collective will to implement, then there is already a technology to solve the problem of heating greenhouses.
The first Steve Bakar who can process the disks with the existing technology, I met a master of carbon counting. Dave, Ray, let's think about how we're going to decorate our house. This is a newly built house. Climate change has really changed here. Our house has started. In the UK they represent a large amount of emissions per household and cause around 25 tons of greenhouse gases each year. They are therefore enormous. Contribute to our climate impact. Let's look inside. So this is a good example of high energy consumption in a home, in fact, much of
the function of this thermostat is wasted. Yes, really. Yes. In any case, this setting is too high for the reduction and saves about a third of the greenhouse gases every year. So this color is going down. Yes. I wear a swimsuit, yes. Clothing adapted to the weather is essential. The coal collected in winter reduces the thermostat by 3 ° and saves electricity bills. It stores a ton of carbon from the atmosphere every year. Watch TV. Yeah, it's
huge. If we look at some of the following devices, even if you aren't watching TV and are in an ordinary house together, we hardly have any electricity-consuming lines, and now they make up about 10% of all those lines. Things pending. This is how they get electricity from the grid. 10% of household electricity consumption. Yes, it's a complete mess, just you sit on the sidelines. Basically, electricity is only there for electricity. It's a little light, I have to say I don't know. It's as high as the rules, if you run out of something, turn it off. It's not that opening our damage causes the
manufacturer to have serious problems, it has to fix them. We can do a lot of things around the house, from composting and plant waste to switching to low-energy bulbs, so it really helps. Just by replacing the lightbulb to protect the arctic ice cap. Some little things are going in the right direction. That's good news because it happens because it's hot, it turns on gas, and it's electric. More insulation, each better than average, you can see 200kg of greenhouse gases. Keeping it clean and buying locally grown food can reduce the number of miles of food in the ground. That's great. If everyone makes the most effective choices
at home and in the office, we'll cut those emissions by a quarter and stop using a Steve Bacale spice for global warming. Maybe the easiest way. Most of us can fight global warming by changing the way we drive. The carbon chose a more economical car. If there are 2 billion cars in the world that can travel 60 miles per gallon by the middle of this century, then that will be seven of the otherthat will cope
rates. Or, if we drive half as much as we do now, it may mean using public transport, and we're adding another part. Another major challenge is to find carbon-free energy. However, it is three times more controversial. Global nuclear power will reduce our future emissions. This is a 3 hectare solar park that aims to collect energy
directly from the sun. Renewable energy sources like solar panels can generate carbon-free electricity in the atmosphere. These can be added to make an important contribution to solving the global warming problem. In a country like China, sola will be very important. However, the UK's climate has never been perfect for solar energy, and there are other natural resources as well. We have many hot countries that are the windiest cities in Europe. It is impossible
to understand the size of these towers unless you approach them like me. Nothing can give you a scale, but they have a rotor diameter of 90 meters. It's almost as long as a soccer field and in my opinion they are great. The best thing about them is that they don't emit carbon dioxide when they work. However, they are not cheap and can be found all over the world. We also need 700,000 turbines. This will reduce another part of global emissions.
It's a very strong wind. Of course, wind farms are just one of many potential sources of new energy. Of course, if we are serious about climate change we need to think more about it. Steve, Popcorn firmly believes that the technology we already have can save us. He'll see newer technology, but it's not much bigger. A hundred kilometers. The coast often lies. Small corkscrew 气 平台。 gas platform. It is one of the largest objects in human history. It sits on the ocean floor and is used only to prevent
damage to the atmosphere. People mining fossil fuels like oil and natural gas have now found a way to emit carbon dioxide into the ground. One million tons of carbon dioxide are pumped into the rock every year. Hundreds of meters under the sea: Norwegians believe it can reduce all carbon dioxide emissions in Europe in the next hundred years, but it will take thousands of such rings around the world to come closer to a solution. It's not a magic ball. This can be the next generation 15% solution. What isto Karres
importantis that we didn't fully understand many things, I call them the monster behind the door. This technique prevents these monsters from entering behind the door. This creates an additional bridge into the future for our children and their children and their children. This is our time and we must begin it so that we can leave them a world where the monster is always behind the door. I'm done. Change is happening in the air and people around the world are aware of the urgency. The problem of global warming needs to be solved. Large economies like China are developing new technologies to cope with rising emissions
and encourage people to get involved in tree-planting drives. Even the smallest ones. Splendid. Okay, let's be clear now. It's not about stopping making tea. The life we are talking about is more or less our previous way of life, but more efficient. Yes, waste is a problem. He's not really alive, make me a cup of tea, I definitely will. So I'll fill it up with water or a seat first. All we need to mix is water.
It doesn't matter what ethnicity it is. He said it was important. Don't waste it. Now that you're making the tea, make it while it's hot. Yes, you don't have a hot pot and I don't have a hot pot. We will see the quality of the teachers. Applause. As you move into the future, it is clear that we can take large and small steps to reduce
CO2 emissions. But since we are talking about the future, we cannot be sure. Where are we going. But one thing is certain. If we do this, we won't end up in deep water. If we continue to heat our planet, we can accelerate the melting of the world ice, which will lead to a catastrophic rise in sea levels. Recent satellite data suggests that the Greenland ice sheet is not just melting. Its execution speed is twice as fast as previously assumed. Scientists are now saying that we are nearing a tipping point and that the complete melting of the Greenland ice is inevitable.
When it melts, the sea level rises up to seven meters. It can take forever, but we should all care. Our actions today can plunge the world into disaster in the future. The combination of melting ice and warming sea water will expand the ocean. This could increase their level by half a meter before the end of this century. If we remember that half of the people live in coastal areas in the world.
Rising sea levels are a daunting decision. There is no email in the British Isles. When the Greenland Ice Sheet melts, the sea will inundate most of the southeast, including central London. Indeed, many of the world's most famous cities will be covered by the sea.
It takes much less time to flood most of Florida. With a height of only 5 meters, most of the land is flooded. The city of Miami is 80 kilometers from the sea, the same altitude will destroy half of Bangladesh. The country has almost 20 million inhabitants, the map has been almost completely flooded. Millions of people are displaced. Scientists around the world predict that in 50 years' time global warming could displace 150 million people from
their jobs. Are you making that kind of change for it, right? Did you get up very deep in the morning and survived? I mean, I think if you treat it as a preconception, prospects can't avoid depression, but I think all climate modelers won't be wrong. So if I just look at these, I will no doubt be very frustrated, not necessarily
my own cause, as we may be able to handle them in the next few decades. In any case, it will be very frustrating for my children, and for some children, for my grandchildren. But I still think there is something we can do. It's a big challenge. Now, on behalf of future generations, certain actions must be avoided. Some of the more serious effects. I have to say, I thought if I looked at my grandchildren and said yes, I knew it was going to happen, but I didn't bother to do anything. Make it terrible. When a generation says we are leaving something like this for future generations, and we know it, isn't that the worst
we know about the problem, but we haven't addressed it? It will be the worst situation we have ever faced and we must avoid it, sir. In the past we did not see the effects of our actions. We sown the wind and now we reap the storm, but we no longer have that excuse. We are now aware of the consequences of our actions. Before we condemn future generations, we must, in any case, individually and collectively reform them nationally and internationally. For the disaster.
