Global sea levels could rise by more than 20 feet if the ice shelves in Greenland and Antarctica collapsed, which is a distinct possibility if temperatures continue to climb. Droughts and wildfires will occur more often. More than a million species worldwide could be driven to extinction by 2050. 3. Does the rise in the earth’s temperature cause more intense storms /hurricanes/ tornados here in the US? If so, how? Answer: While it is impossible to blame any single event on global warming, there are several reasons to believe that global warming will create more intense storms. Hurricanes are powered by warm water on the surface of the ocean. As global warming heats the surface of the water, hurricanes will increase in speed, power, and frequency. Tornadoes are caused by rapidly rising amounts of heat from the lower areas of the atmosphere to higher portions of the sky. While scientists are again reluctant to pin individual storms on global warming, global warming does create greater amounts of heat in the lower portions of the atmosphere, creating more tornadocausing energy to be released into the upper atmosphere. 4. What are the largest sources of global warming pollution in the world and in the United States? Answer: The US produces far more carbon dioxide than any other country in the world. According to the latest figures by the Department of Energy, the US produces 22% of all CO2 emitted into the atmosphere, at 5, million metric tons in 2020. That is more than China, and India together (17% and % respectively), more than Russia (6%), Japan (%), Australia (%) and the whole of Europe put together (%). In the United States, the major sources of CO2 emissions stem from burning fossil fuels, like coal, natural gas, and oil. We burn coal and natural gas to produce electricity and energy for our homes, businesses, and factories, while most of the oil is burned to power transportation, planes, buses, and especially cars. However, all of the technology that produces this energy is outdated and inefficient. We can continue to live our lives by putting more efficient technology to use, and by getting more energy from clean sources, like wind and solar. 5. Can we curb our emissions of global warming pollution without hurting our economy? Answer: Absolutely. In addition to being dirty and dangerous, America’s coal and nuclear power plants are wildly expensive, America39。 176。 I can39。 Look ahead in the distance, and you can see the lights of the village. 你往遠處看，便可以看見村莊里的燈光。 understandably, when tens of thousands of people are dead and most buildings are in ruins, there are more important things to do than to count bodies. However, there have been about five quakes in the twentieth century where reports of lives lost exceeded 100,000. Most experts accept that the most deadly earthquake in historical times occurred in Shanxi Province, China in 1556。 ways 過程與方式 Step I Revision Check the homework. Point out the mon errors students have made. Step II Awareness Ask students to read the three disasters on Page 17. Then they will discuss in groups. Each member will speak out what they know about the worst disasters. After they discuss what the worst disasters in history are in groups, each of them will write what he or she knows on board. The whole class will exchange their information. If students have an access to the Inter, they may find what they need easily. If they don’t, Teacher may provide some.
