S2 GEOGRAPHY 1 S2 Climate Change Unit Why should we learn about climate change? Many people make Climate Change and Global Warming a scary and difficult thing to understand, but it’s not. Scientists have warned that the world's climate has changed a lot, and has affected many living and non-living things. Many places that were warmer are now getting colder, and many colder regions are getting much colder or even warmer. Some people do not believe that these are caused by human activities. They think it is all political and story telling intended to cause panic among humans. Well, whatever it is, hopefully you would like to know more, and take a few good points from this confusion, and use them to make our world a better place to live. If there are any words that you are not sure of in the unit try checking the back of this booklet – there you will find a glossary of all the important terms we will talk about. If you don’t find what you are looking for there ask your teacher and they will help you. What are we going to learn about in this unit? Learning Objectives: To understand… what is meant by ‘global footprint’ and to calculate your own. what is meant by the term ‘global warming’. what the ‘greenhouse effect’ is and how it occurs. the natural and human causes of climate change. the role that humans play in contributing to climate change. how burning fossil fuels can create problems on a global scale. the difference between renewable and non-renewable energy sources. some of the effects of global warming around the world. how we might start to experience more extreme weather if global warming continues at it’s current rate. what our world might look like in the future if humans don’t change their ways soon. 2 The CfE Experiences and Outcomes you will cover in this unit include: I can identify the possible consequences of an environmental issue and make informed suggestions about ways to manage the impact. SOC 3-08a I can investigate the climate, physical features and living things of a natural environment different from my own and explain their interrelationship. SOC 3-10a I can discuss the sustainability of key natural resources and analyse the possible implications for human activity. SOC 4-08a I can develop my understanding of the interaction between humans and the environment by describing and assessing the impact of human activity on an area. SOC 4-10a I can identify threats facing the main climate zones, including climate change, and analyse how these threats impact on the way of life. SOC 4-12a I can carry out a geographical enquiry to assess the impact and possible outcomes of climate change on a selected region and can propose strategies to slow or reverse the impact. SOC 4-12b 3 Lesson 1: An Introduction to Climate Change Climate change has happened naturally many times before. The difference now is that the change is happening quickly and humans are speeding it up. Climate change is one of the biggest threats to our environment. It will have a massive effect on how we live. The earth is getting warmer because of a buildup of greenhouse gases in the atmosphere. These gases trap heat from the sun. The most important greenhouse gas is carbon dioxide. Scientists have calculated that for temperature increases to be held to a maximum of 2°C by 2050 the average global emissions per person should be 2 tons. Currently the global average is around 4 tons per person. Climate change is not a small challenge. Big reductions are needed and schools have to play a part in this. TASK 1: In groups of 3/4 write down in your jotters ways that you each contribute to the amount of greenhouse gases in the atmosphere, separate your answers into 3 sections: 1) Before School 2) In School 3) After School Each thing you do produces different amounts of CO2. These measurements are used to calculate your carbon footprint Ecological Footprint Your ecological footprint is the amount of land needed to sustain your life on earth. If all the land on Earth is divided by the world’s population we can get some idea of what our ecological footprint should be. The figure that has been calculated is 1.8 hectares. By asking ourselves questions about our own environmental behaviour we can get some idea of how big our individual ecological footprint actually is. 4 TASK 2: Calculate your eco footprint out of 50. Answer the questions on the separate sheet your teacher has given you. Once you have answered all the questions calculate your own footprint using the information below. Copy the paragraph that relates to your amount into your jotter. How Big Is Your Footprint? How did you do? For each a score 10, for each b score 5 and for each c score 0. Big Feet if you have a score of 35+ Oh dear. It does not look like you've been at you're greenest. What you need to realise is that adopting environmentally-friendly behaviour does not have to hurt. Perhaps you're worried that you'll have to sacrifice too much if you 'go green', but this needn't be the case. Small changes in behaviour can benefit the environment. Average Feet if you score 20-35 You're doing OK. Maybe you recycle your waste or try to save electricity. However, when it comes to green behaviour there's always more that you can do. Little Feet if you scored 0-20 Your halo is really shining. At this rate you'll soon be knitting your own tofu. Joking aside you're making a really commendable contribution to the wellbeing of the planet. Global Footprint EXTENSION TASK Draw two footprints onto plain paper. a) Divide one of the footprints into sections and decorate it to show each aspect of your footprint: water, heating, paper, holiday, waste, transport, food, electricity. b) Now using the other footprint that you have drawn on the paper, divide it into sections and decorate it to show how you could reduce each aspect of your footprint e.g. water - turn the tap off when you brush your teeth, heating - turn the thermostat down, etc. 5 Lesson 2: Global Warming The average global temperature has risen in the last hundred years – and the years since 1980 have been the hottest on record. Global warming has a two sided argument on the causes – these can be broken into natural causes of climate change and human activities that result in climate changes. TASK 3: Copy a table like the one below into your jotters. Complete the table using the words in the word bank. Natural Causes Word • • • • • • • • • Human Causes Bank Explosions on the sun, creating sun spots Large volcanic eruptions Burning fossil fuels Deforestation (burning trees producing CO2) Methane is released from rubbish dumps Changes in earth’s orientation towards the sun Nitrous oxide is released from car exhausts and fertilisers Changes in the earth orbit Chlorofluorocarbons CFC’s from aerosols and fridges 6 How Will Global Warming Affect Us? Scientists agree that the earth will continue to grow warmer during the 21 st century, but they do not agree about the causes or possible effects. The Sun is Blamed for Global Warming Scientists have dismissed claims that we can halt global warming by drastically cutting our consumption of fossil fuels. New evidence has shown that the main causes of global warming is in fact the sun. The temperature rise, previously blamed on fossil fuels, is mainly due to an increase in the suns energy output. This increases periodically making the earth warmer. An increase of just 0.2% in solar output has the same affect as doubling the amount of Carbon Dioxide in the atmosphere. Disaster Ahead, Warns the UN The UN has warned of global environmental disaster if rich countries do not cut back on their fossil fuel consumption. The increase in Carbon Dioxide from burning fossil fuels is mainly responsible for global warming. Industrialised nations such as Britain could have to cut back on their use of oil by as much as 90% to help avert catastrophic flooding and storms around the world. Global Warming is Natural, say Industrialists. An American report has concluded that global warming is almost entirely natural and will happen anyway no matter how little fossil fuel we burn. The amount of carbon dioxide added to the atmosphere by industry makes virtually no difference. Environmentalists say they expect the report to reach this conclusion, since the research was paid for by American Industrialists. The USA produces over 20% of the worlds Carbon Dioxide, although it has only 5% of the worlds population. Global Warming – Cooler Britain? Scientists in Britain are sharply divided over the possible effects of global warming on our islands. Some say that global warming will mean a rise in temperature of about 3oC by the end of the 21st centaury. An alternative viewpoint indicates that the opposite may happen, as the northern polar ice cap begins to melt, a vast surge of cold water from the North Pole could replace the warm North Atlantic Drift. The overall effect of this would be that temperatures in Britain could fall by 3oC. TASK 4: Read the above newspaper clippings and answer the questions below. 1) Summarise the view on global warming outlined in each extract. 2) Why do you think experts can’t agree about the causes or effects of global warming? 3) Why might some people such as industrialists want to argue that global warming is a natural process? 4) Write a short paragraph about your own opinion. Do you think global warming is a major problem? Is it important to you? Who should take responsibility for global warming? 7 Lesson 3: What Is The Greenhouse Effect? The Earth’s atmosphere acts like the glass in a greenhouse. It is needed to keep the planet warm enough for life to exist. Sunlight passes through the Earth’s atmosphere and the Earth gives out infrared radiation. Certain gases trap some radiation in the atmosphere, which keeps the Earth warm. This is called the greenhouse effect. Having some greenhouse gases is a good thing. If it wasn’t for these gases, Earth would be too cold to live on! However, the presence of too many greenhouse gases can have a negative impact on the Earth. TASK 5: Copy the following paragraph into your jotters The Earth is kept warm by the atmosphere, a blanket of gases that act like the glass of a greenhouse. The greenhouse effect is the name given to the process which causes the Earth to be warmer than it would have been in the absence of an atmosphere. Having some greenhouse gases benefits the planet…but humans keep adding to the greenhouse gases. TASK 6: Copy the following diagram into your jotters. Solar Radiation Some of this heat is then trapped by the atmosphere. The Earth absorbs some of the sun’s energy and gives it out in the form of heat. 8 TASK 7: Watch the following clip and then copy and complete the paragraph below using the word bank: https://www.youtube.com/watch?v=x_sJzVe9P_8 The _ _ _ _ _ _ _ _ _ _ allows heat in.

Word Bank Freezing Greenhouse Heat Atmosphere Gases 9 Lesson 4: Causes of Climate Change As we have already discussed, climate change has both natural and human causes. More than 100 years ago, people around the world started burning large amounts of coal, oil, and natural gas to power their homes, factories, and vehicles. Today, most of the world relies on these fossil fuels for their energy needs. Burning fossil fuels releases carbon dioxide, a heat-trapping gas, into the atmosphere, which is the main reason why the climate is changing. TASK 8: Watch the following clip and answer the questions below: https://www.youtube.com/watch?v=RHrFBOUl6-8 1) What is the driving force behind Earth’s climate? 2) What happens to energy from the sun that gets through the Earth’s atmosphere? 3) What do greenhouse gases act like? 4) What would happen if there were no greenhouse gases? 5) Explain how volcanoes can naturally affect Earth’s climate. 6) How much of our energy in the UK comes from fossil fuels? 7) What happens when fossil fuels are burned? 8) What is all the extra CO2 doing to the atmosphere? Why is this bad? 9) What do plants and trees do with CO2? 10) Why are forests being cut down? 11) How big is the Amazon rainforest? 12) How much are temperatures predicted to change over the next 100 years? 13) What has happened to large areas of the polar regions due to climate change? Why is this bad? 14) What did the United Nations set up to help review research on climate change? 15) What were the findings of the IPCC? TASK 9: Discussion: Do you think humans will be willing to cut back on their use of fossil fuels in the future? Write a short paragraph summarising your view and the views of your group. Make sure to fully explain why you and your group think the way that you do. 10 Lessons 5 & 6: Human Causes of Climate Change Deforestation Deforestation is the cutting down and clearing away of trees. Deforestation used to be something that few people apart from environmentalists talked about, but in the last 20 years or so it has received increasing attention from governments and the media, and is now considered to be one of the world’s most serious environmental problems. Deforestation leads to the extinction of many species of forest animals and the erosion of soil after trees have been removed, but the consequence of deforestation that we hear most about is its contribution to global warming. Trees naturally absorb carbon dioxide (CO2) from the Earth’s atmosphere, so less trees means higher levels of CO2, which contributes to the atmosphere becoming warmer. Many scientists estimate that about 20% of global warming is due to deforestation. Deforestation is taking place mostly in developing countries in tropical regions of South and Southeast Asia, Central and South America, and Africa. Perhaps the most well-known case is the decreasing size of the huge Amazon rainforest in northern Brazil. 11 Many people around the world say these developing countries should do more to protect their forests – although the developing countries could point out that most of the world’s developed countries destroyed most of their own forests many centuries ago. In some cases deforestation is caused by poor people who want to use the wood for fuel or to clear a small amount of land in order to grow food for their families. In many cases, however, it happens because there are large profits to be made – for example from selling the wood, or from growing crops (such as soybeans) or raising animals (such as cattle, for beef) on the land after the trees have gone. Produce from deforested land is often exported, so there is often a link between what people choose to buy in their local shops and what happens to forests in countries thousands of miles away. TASK 10: Your teacher will give you a blank map of the world. Use the map on the previous page and the PowerPoint to help complete your own map showing the countries where deforestation is the most extreme. Don’t forget to include a key to show what each colour represents! Increase of Methane Methane is the second most significant cause of greenhouse warming, behind carbon dioxide. Bessie, the cow, and her many brothers and sisters are one of the greatest methane emitters. Bessie's grassy diet and multiple stomachs cause her to produce methane, which she exhales with every breath. The sheer size of her herds makes a significant contribution to global warming. This cow is not camping, but living the green life. A catheter carries methane gas from her intestine to her backpack. It's part of a pilot program in Argentina to create energy for outlying areas. (Photo: intainforma.inta.gov). 12 TASK 11: Using the graphs above answer the following questions: 1) What do you notice about the world population and the amount of methane in the atmosphere? 2) Can you think of any reasons for this? Transport Emissions Transport accounts for at least 22% of greenhouse gas emissions in the EU and this is set to continue growing. Between 1990 and 2006, transport emissions increased by almost 35% while emissions from other sectors decreased by about 3%. UK Greenhouse Gas Emissions from Transport Vehicle Percentage Cars and Taxis 58 Heavy Goods Vehicles (HGVs) 17.2 Light Vans 12.5 Buses and Coaches 4.3 Motorcycles 0.5 Rail 1.8 Domestic Aviation 1.6 Domestic Shipping 1.3 Other 2.8 As you can see from the table above, car and taxi transport accounts for over half of all transport emissions. Total greenhouse gas emissions from all forms of road transport amounted to 125.3 million tonnes in 2002, an increase of 13% 13 since 1990. Greenhouse gas emissions from road transport now make up 18% of all greenhouse gas emissions compared with 14% in 1990. In 2015 Volkswagen became embroiled in one of the biggest corporate scandals of recent years. The German car maker had been installing "defeat devices" software that allowed cars to cheat in emissions tests, making them appear cleaner than they actually were. Volkswagen's software allowed it to beat the tests in a lab, but when on the road with emissions controls switched off, cars would pump out nitrogen oxide a pollutant - at up to 40 times the legal limit. The software "knew" when it was being tested, allowing it to switch emissions controls on and off. Volkswagen had been installing the software in certain models of its cars for at least six years. While investigating the scandal, VW found that around 800,000 cars also had irregularities around carbon dioxide (CO2) emissions, which contributes to global warming. Volkswagen has admitted that there were 11m vehicles with the cheating software, including Audi, SEAT and Skoda models, as well as VW vans. Around 1.2m cars in the UK were affected. However, Volkswagen is not the only car manufacturer whose cars emit more than they are legally allowed. TASK 12: Create a bar graph using the information from the table titled ‘UK Greenhouse Gas Emissions from Transport’ on the previous page. 14 Air Transport Organic farmers face ruin as rich nations agonise over food miles 50% increase of organic produce sold in Britain is imported. 140% increase in the carbon footprint of air freighted food to Britain since 1992 150,000 in Kenya depend on organic farming A group of 34 farmers, the Waging Organic Farmers’ Group, in a village outside Nairobi, Kenya, live in a brick and corrugated iron dwelling, have no car, use little electricity, fertilise with cow manure, live off less than 50p per day. They changed to organic farming 4 years ago by learning new techniques. This was a prime example of ‘Trade not Aid’. However, they are facing financial ruin because the Soil Association, which certifies 80% of organic produce in the UK, has threatened to take away their organic certification because their produce is transported to Britain by air. The Times Newspaper, August 2 2007 TASK 13: Write a letter to the times newspaper in reply to this report. In your letter you should write if you agree or disagree with importing food from different countries, you should give quotes from the newspaper report to back up your letter and also use your background knowledge in order to get your point across. 15 Lesson 7: Burning Fossil Fuels Fossil fuels include coal, oil and gas. These are called fossil fuels because they have been formed from the fossilized remains of prehistoric animals and plants. Fossil fuels provide around 66% of the world's electrical power and 95% of the world's total energy demands (including heating, transport, electricity generation and other uses). Each year the world releases more than 6 billion tonnes of carbon in the form of carbon dioxide (CO2) from the burning of fossil fuels (oil, coal and gas). These emissions have continued to increase at around 2% per year for several decades. The burning of fossil fuels is responsible for 80% of global man made greenhouse gas emissions. How it Works Energy Thieves 1. Electrical appliances – switch them off! TVs, DVD players, PlayStations, Xboxes, Wiis, phone chargers, computers, projectors, electronic whiteboards – all eat lots of energy in ‘standby mode’. A photocopier left on overnight uses enough energy to produce over 1,500 copies. 2. Radiators – turn down the heat! Keep your thermostat at 18-20°C. Put a jumper on if you are cold. 16 3. Lights – do you really need them on? Switch off lights when you leave a room. Traditional light bulbs waste 90% of the electricity they use as heat. Energy saving light bulbs last around 10 times longer – switching just one bulb could save 26 kilograms of carbon dioxide a year! 4. Windows and doors – keep them closed! When you leave doors or windows open, and radiators on, heat escapes through the open spaces. Your radiators will have to use more energy to heat your school or home. What a waste! Task 14: Energy Savers Game! You are going to play a board game to help you understand how YOUR energy use can link to global warming. Collect a set of instructions, a game board, a set of game cards, a bag of stars and a die from your teacher. Who has the most energy-saving stars? Task 15: Design a ‘Stop the energy thieves’ poster for other classes to look at. Homework 1: Another way that we can prevent energy waste is by reducing the amount of rubbish we create, reusing items whenever we can and recycling what we can’t reuse. Your teacher will give you a worksheet titled ‘How much of a waster are you?’ You are going to record the amount of rubbish that you and your family throw away in one week. Once you have completed this answer the questions based on your results. 17 Lesson 8: Renewable and Non-Renewable Resources Humans use the environment for lots of different reasons. We use the natural resources provided by the environment, such as coal and water. Resources are things that we need to live: for example, we use coal to produce power and we use water to drink, wash and cook with. We use lots of resources to give us energy – power. Some of these resources that provide us with energy are renewable. This means that they can be used over and over again. Other resources are non-renewable. This means that when they have been used they cannot be used again. TASK 16: Can you tell which of these natural resources are renewable and which are nonrenewable? Copy the following into your jotters and write beside each if they are renewable or non-renewable. Coal Water Wind Wood Oil _______________________________________ _______________________________________ _______________________________________ _______________________________________ _______________________________________ Renewable Energy 1. Hydroelectric Power (HEP) HEP is the most popular type of renewable energy. In some countries, it represents most of the energy produced. HEP provides over 70% of Brazil’s electricity and about 20% of world electricity supplies. A dam is built to trap water, usually in a valley where there is an existing lake. Water is allowed to flow through tunnels in the dam, turning turbines and driving electricity generators. HEP stations can produce a great deal of power very cheaply. 18 2. Solar Energy The Sun is 150 million kilometres away, and amazingly powerful! Just the tiny fraction of the Sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over. In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year…if only we could harness it properly. 3. Wave Energy Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy. The problem is that it's not easy to harness this energy and convert it into electricity in large amounts. At a wave power station, the waves arriving cause the water in the chamber to rise and fall, which means that air is forced in and out of the hole in the top of the chamber. A turbine is placed in this hole, which is turned by the air rushing in and out. This turbine turns a generator which then supplies the electricity. 4. Wind Power A wind energy system transforms the moving energy of the wind into mechanical or electrical energy that can be used. 19 A wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which connect to a generator and make electricity. 5. Geothermal Energy The centre of the Earth is around 6000°C- easily hot enough to melt rock. Even a few kilometres down, the temperature can be over 250°C if the Earth's crust is thin. In general, the temperature rises 1°C for every 30 - 50 metres you go down. Sometimes we can use that heat. Geothermal energy has been used for thousands of years in some countries for cooking and heating. The name "geothermal" comes from two Greek words: "geo" means "Earth" and "thermal" means "heat". Hot rocks underground heat water to produce steam. We drill holes down to the hot region, steam comes up, is purified and used to drive turbines, which drive electric generators. 20 TASK 17: The Lewis Wind Farm Debate A new wind farm is proposed to be located on the Isle of Lewis in Scotland. Isle of Lewis The £500 million project could make the UK a leader in clean energy. The projects first stage would see 234 of the world’s largest wind turbines towering over thousand of acres of land on the Isle of Lewis. Britain could double its renewable energy capacity! The electricity generated would be exported via a 350 mile undersea cable, possibly to Merseyside or North Wales. 1. Put the heading ‘The Lewis Wind Farm Debate’ in your jotter. 2. Divide your page into 2 – on one side put the heading ‘for’ and on the other put ‘against’. 3. Now you will be divided into groups of 3/4. Each person will be given a card that represents the view point of different groups. 4. Take it in turns to read out your view point to the rest of the group. 5. Then as a group decide whether the views are for or against the development. 6. List them under the correct headings in your jotter and say why they are for or against the wind farm. 7. Having heard the arguments for and against, what do you think? Write a paragraph in your jotter explaining your opinion. 21 EXTENSION TASK Listed below are six ways that you can help conserve energy. Match the start of the sentence (the head) with the correct end of the sentence (the tail). Copy each complete sentence into your jotter. Heads 1. Do an energy audit in your home. Check ways to make your home more energy efficient. Make energy… 2. Plant shade trees around your house. This will make your house… 3. Recycle where possible. Recycling certain items such as aluminum cans can save… 4. Try to buy recycled products, and buy products that… 5. Use your appliances efficiently. For example, run dishwashers and washing… Tails …exercise and it saves energy! …saving changes if possible, such as improving insulation, installing storm doors and windows, stopping drafts under doors and around windows, and installing devices that reduce hot water consumption. …warm clothes inside your house! In the summer, wear cool, loose clothes. Try not to turn on heating until it gets really cold. … enormous amounts of energy. … use minimum packaging. 6. Dress for the season! In the winter, wear…. …machines only when you have full loads, wash clothes in cold water, don’t overheat your hot water, use a clothes line instead of the dryer. 7. If possible, walk or ride a bike to school or around town. It’s good…. … cooler and lessen the need for air conditioning in the summer. 22 Lesson 9: Effects of Global Warming Global warming is already having significant and costly effects on our communities, our health, and our climate – locally and on worldwide scale. Increasing global temperature means that ecosystems will change; some species are being forced out of their habitats (possibly to extinction). Lessened snow cover, rising sea levels, and weather changes, may influence not only human activities but also plants and animals. Animal and plant species are becoming extinct at an alarming rate. It has been estimated that in the rain forests alone, over a hundred plant, animal and insect species are lost each day! Some other effects of global warming are show in the diagram below: We are now going to look at some of these effects in greater detail. 1. Rising Sea Levels If global warming continues, the oceans will heat up and expand causing an increase in the level of the sea. The melting of ice sheets in Greenland and Antarctica could be another major cause of sea level rise. Sea levels have been rising by about 1-2mm each year for the past 100 years. Current predictions suggest that the sea level may rise by another half a meter in the next 100 years. Higher sea levels will threaten the low-lying coastal areas of the world such as the Netherlands (Holland) and Bangladesh, and many low-lying islands in the Pacific and Indian Oceans. 23 TASK 18: 1) Write a short paragraph on what the comic above is trying to show. 2) Draw your own comic or series of comics with the theme of ‘sea levels rising’. 2. Species Threatened Animals and plants that are suited to cooler climates will need to move further towards the poles when the climate becomes even just that little warmer. Fish in the North Sea have been observed moving northwards too – fish stocks that used to be common around Cornwall have moved as far north as the Shetland and Orkney Islands! Scientists predict that global warming could contribute to the mass extinction of wild animals in the near future. An overheating world is creating a big change in climatic conditions and this can harm the delicate ecosystems in which species live. Threatened species can already be found all over the world. TASK 19: ICT – Complete for homework (2) Choose an animal from the next page, or any other species that are at risk as a result of climate change, and write a report on that animal. You should include: • Where the animal lives. • Why is it under threat? • Possible ways the species can be helped. A useful website to use is the World Wildlife Fund: http://wwf.panda.org/about_our_earth/aboutcc/problems/impacts/species/ 24 Species Threatened By Climate Change Canada - The Polar Bear South America - Sea Turtles America - The North Atlantic Right Whale China - The Giant Panda Indonesia - The Orang-Utan Africa - Elephants Australia - Frog India - Tigers 25 Lesson 10, 11 & 12: Extreme Weather Extreme weather and natural disasters occur all the time all over the world. These include heat waves, river and coastal flooding, droughts, landslides, storms, hurricanes, tornadoes. However, if the Earth warms up because of manmade pollution, some of these extremes may become more intense and may occur more frequently. This may have a negative effect on society as these events damage homes and villages and can lead to loss of life. Global warming is expected to increase the amount of moisture in the air because more water is evaporating from ponds, rivers, lakes, and oceans. In many places this will lead to an increase in rainfall causing more frequent floods and landslides. However, some places may receive less. TASK 20 1. Your teacher will let you watch PART of the DVD – “The Day After Tomorrow.” 2. While watching the film you should be taking notes on some of the main effects of global warming and how the environment and the weather change. 3. In small groups write your own 5 minute short film script based upon what you have seen in “The Day After Tomorrow”. 4. Perform your play in front of the class. 26 Lesson 13: Global Warming in the Future TASK 21: It is the year 2106. Global warming has happened, with a 5°C rise in global temperatures and the melting of the sea ice at the poles. London is no longer Britain's capital city, weather patterns all over the world have changed, and huge areas of the world, including Bangladesh and much of Egypt, are under water. Write a report as though you were a historian looking back to the events of 2000–2015. You might want to mention: • How climate change began to happen? • Why was so little done to prevent the problem? • Who was to blame? • What lessons have been learnt? Plus any other information that you can include. The report should be a minimum of 1 A4 page.
