Environmental Protection Reading and Thinking Unit 3 1 Leading in 1.What disasters are mentioned in the video? drought flood global warming animals dying fire Glaciers melting By the end of this class, we will be able to 1. know the causes and consequences of climate change. 2. explore practical ways to address climate change. 3. figure out effective information on graphs and diagrams. Learning objectives Look at the graph. What information can you get from it? The earth is becoming warmer and warmer. Pre-reading The Global Surface temperature is abnormal and rising. The graph shows the change in the Global Surface Temperature between 1920 and 2016. Now, let's read the passage to find out whether you are right. 5 What can you see in the photo? The polar bear (北极熊) was skin and bones and starved to death. While-reading: read for the structure and main idea Part 1: (para.1-2 ) Part 2: (para. 3) Part 3: (para. 4) Part 4: (para. 5) The evidenceof dramatic climate change that had an impact on Earth’s ecology The causes of the increase in the global average surface temperature The consequencesof the rise in temperature The solutions to reducing greenhouse gas emissions Match the main idea with each part. the development of the passage problem example reasons influences solutions phenomenon cause effect solution Expository writing 按照“现象—原因—危害—措施”的逻辑顺序展开，环环相扣，步步深入。标题Climate Change Requires the World’s Attention点明了作者的诉求：气候变化对地球生态系统的影响是巨大的，需要全人类共同关注和面对。 8 Read for details Evidence (para.1-2) 1.What evidence of climate change can you find? Evidence 1: Evidence 2: Evidence 3: a warming ocean and atmosphere melting ice rising sea levels climate change Evidence 4: a dead polar bear 9 2. Can you describe how climate change has influenced the polar bear’s life? Climate change low sea-ice levels could not hunt had to travel greater distances for food starved to death Read for details Causes (para.3) natural man-made Definition Heat from the sun enters the __________ and warms Earth’s __________ as _________ radiation. Function Keeping Earth’s warm and_____________ Definition People produce huge amounts of_________ greenhouse gases by burning_____________. A big problem More ________ energy is trapped in the atmosphere and causes Earth’s surface temperature to ________ quickly. habitable extra fossil fuels atmosphere surface short-wave heat rise Greenhouse Effect 11 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? The rise in temperature led to extreme weather natural disasters result in extreme rainstorms heat waves serious damage costing human lives economic losses example Consequences (para. 4) 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? Solutions (para. 5) solutions governments make policies take appropriate actions and measures individuals reduce our “carbon footprint” by… educate everyone about global warming Heat released back into space Heat reflected back to Earth’s surface Reflected sunlight Atmosphere Sunlight Draw a diagram to show how the “greenhouse effect” works. Draw a diagram 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.

Group discussion As a student, what can we do to reduce our “carbon footprint” ? As a student, what can we do to reduce “carbon footprint” in our daily life? litter tree transportation light eat ... Thinking A carbon footprint is historically defined as"the total set of greenhouse gas(GHG) emissions caused by an organization, event, product or person", usually expressed in equivalent tons of carbon dioxide (CO2e). 碳足迹指的是由企业机构、活动、产品或个人引起的温室气体排放的集合。温室气体排放渠道主要有:交通运输、食品生产和消费、能源使用以及各类生产过程。通常所有温室气体排放用二氧化碳当量(CO2e)来表示。 2.Discuss in groups:what can we individules do to help reduce “carbon footprint”? Turn off the lights, computers etc. the moment you don’t need them. Sort out the garbage Use renewable energies Stop using plastic bags Use the minimum paper, backing paper etc. Take green transportation Take a shower instead of a bath plant more trees Take the stairs instead of elevator Earth provides enough to satisfy every man’s needs, but not every man’s greed.— Mohandas K.
