Climate Change Q & A Whats going on with the earth? What is threatening us in the future? Climate Change has brought destructive influences. The global warming effect is an accumulated result and human beings are the contributors. To save the earth, everybody should know what we can do to help cool down the earth. Lets answer the following questions to learn how we have to face our future.
Climate Change Q & A Q1: What causes global warming? A: That mankind uses too many fossil fuels has increased the release of greenhouse gases (GHGs) into the atmosphere and contributed to rising global surface temperature and climate change. Greenhouse gases cause global warming.
Climate Change Q & A Q2: How do greenhouse gases affect the earth? A: If greenhouse gases emit too much, the earths temperature rises and they cause global warming.
Climate Change Q & A Q3: What are greenhouse gases? A: They are carbon dioxide (CO 2 ),, methane (CH 4 ), chlorofluorocarbons (CFC S ), nitrous oxide(N 2 O) ozone (O 3 ), and so on.
Climate Change Q & A Q4:What are these gases? A: Carbon dioxide-Due to extensive use of coal, oil, natural gas and other fossil fuels. Chlorofluorocarbons-Such as the use of air conditioners, refrigerators of Freon, electronic parts cleaners, aerosol sprays, five extinguishers, etc.
Climate Change Q & A A: Methane-Arise from changes in the process of fermentation and corruption, mainly from livestock, rice paddies and landfill emissions. Nitrous oxide-Caused by the burning of fossil fuels, microbial and chemical decomposition of emissions is expected to take. Ozone-From the ground contamination, such as steam, locomotives, power plants, oil refineries emit nitrogen oxides, ozone photochemical role.
Climate Change Q & A Q6: How does global warming affect the earth? A: Due to global warming, climate change brings the earth destructive disasters. They include droughts, floods, severe storms, tornadoes, hurricanes, ice storm, and so on. Climate change could also increase the frequency and intensity of typhoons and floods. These disasters make living things on earth narrow their living region and lack water and food.
Climate Change Q & A Q7: Because climate change increases the intensity of typhoons and floods, how did it hit Taiwan heavily this year? A: On August 7-9, Typhoon Morakot brought the worst flooding in 50 years. Many people died and a lot of roads were washed away. Agricultural and fishing losses were great.
Climate Change Q & A Q8: Owing to climate change, how is Taiwan affected by in the future? A: Taiwan, a subtropical island, is very vulnerable to the impacts of climate change. The impacts could include a rise in the sea level and a lack of water resources, as well as adverse effects on primary industries, public health, and ecosystems.
Climate Change Q & A Q9: What can people in Taiwan do to help the earth cool down? A: In Taiwan, the government has to fulfill its duty as a member of the global village. People in Taiwan also should help to reduce GHG emissions. We have to conserve energy. By sharing our common responsibility, we can protect the earth's environment together and achieve sustainable development for our future generations.
Climate Change Q & A Q: Give two examples of natural disasters in ecosystem due to climate change. A: A particular species of purple-spot butterfly will migrate to the place at a higher latitude. The time of animals hibernation will be disturbed.
Climate Change Q & A Q: Give some examples of natural disasters due to climate change. A: Such as reduction of arable land, widespread shortage of water, lack of food, economic damage, desertification, and loss of land.
Climate Change Q & A Q: Who should take responsibility for solving the problems of greenhouse effect? A: Everyone should help.
Reflections on Climate Change These years, we have been suffering from floods or drought caused from climate change. Since we know all these disasters result from what we have done, we should take responsibility for it and help solve the problems.
