Evidence 1 Evidence 2 Evidence 3 problem The ______ is getting warmer and warmer. a warming ocean and atmosphere melting ice rising sea levels Earth Read each Para in detail to find out needed information. ✎ Read for details ✎ P2. In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology. Summarize the example of the increase in temperature that had an impact on Earth’s ecology. ✎ Read for details ✎ Summarize the example of the increase in temperature that had an impact on Earth’s ecology. Time 2013 Where ____________________________ What happened ____________________________ How did it happen? ____________________________ ____________________________ Norway’s Arctic island of Svalbard A bear starved and died. The bear couldn’t hunt seals as before due to the increase in temperature. ✎ Read for details ✎ P3.Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly. natural man-made 1. Heat from the sun enters the __________ and warms Earth’s ________ as _______-wave radiation. 1. People produce huge amounts of ________ greenhouse gases by burning __________. atmosphere Greenhouse Effect 2. Trap the heat,keeping Earth’s warm and ________. 2. More ______ energy is trapped in the atmosphere and causes Earth’s surface temperature to ____ quickly. ✎ Read for details ✎ surface short habitable extra fossil fuels heat rise Draw a diagram describing how the greenhouse effect works. Heat reflected back to Earth’s surface Reflected sunlight Atmosphere Sunlight Diagrams are very useful tools that can be used to brainstorm ideas, map out processes, show cause and effect relationships, explain a new idea or concept, and so on. When you read an essay about scientific issues, you can try drawing a diagram, which will not only allow you to visualise the problems more clearly but also can help demonstrate your creative thinking and problem-solving. Heat released back into space ✎ Read for main idea and structure ✎ P4.There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses. What are the consequences of global temperature rise? Finish the mind map. The rise in temperature led to extreme weather natural disasters result in extreme rainstorms heat waves serious damage costing human lives economic losses example ✎ Read for details ✎ P5.Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help? What are the solutions to the environmental problems? ✎ Read for details ✎ What are the solutions to the environmental problems? governments individuals make policies take appropriate actions and measures reduce our “carbon footprint” by… educate everyone about global warming solutions There is little doubt 1.________ our earth is becoming warmer and warmer.
