Climate Change

• Q: What are two long term changes?

  A: average temperature and precipitation
• Q: What is climate change?

  A: series of long term changes in climate
• Q: What should we expect will change per year?

  A: level of rainfall, average temperature, number of typhoons
• Q: What is the rise of the earth's average temperature?

  A: global warming
• Q: When and why did the planet start getting warmer?

  A: 1980, Industrialization
• Q: What are the 5 things that cause global warming? (PMDFC)

  A: 1. power generation

  2. manufacturing goods

  3. deforestation

  4. food production

  5. car-centric transportation
• Q: What do greenhouse gases (GHGs) abnormally change?

  A: global temperatures
• Q: What are GHGs capable of doing?

  A: absorbing and emitting heat
• Q: What is the warming process caused by GHGs called?

  A: greenhouse effect
• FTB: CO2 emissions and global temperature are directly proportional because when one rises the other one does too
• Q: What are the four main greenhouse gases?

  A: carbon dioxide, methane, nitrous oxide, fluorinated gases
• Q: What is the most abundant greenhouse gas among the 4?

  A: carbon dioxide
• Q: What takes up 3% of the greenhouse gases?

  A: fluorinated gases
• Q: What takes up 5% of the greenhouse gases?

  A: nitrous oxide
• Q: What takes up 10% of the greenhouse gases?

  A: methane
• Q: What takes up 82% of the greenhouse gases?

  A: carbon dioxide
• T or F, replace: All of the sun's energy is reradiated from the surface

  A: F, some
• T or F, replace: GHGs absorb the sun's energy

  A: T
• T or F, replace: GHGs reradiate with some escaping energy back towards the surface, this makes the temperature hotter

  A: T
• Q: Is the greenhouse effect good or bad?

  A: depends
• Q: In what direction do typhoons travel?

  A: northwest
• Q: Give the characteristics of the natural greenhouse effect

  A: 1. more heat escapes into space

  2. less re-emitted heat
• Q: Give the characteristics of human-enhanced/artificial greenhouse effect?

  1. more re-emitted heat,
  2. less heat escapes into space
  3. more greenhouse gases
• SC: Too much of Carbon dioxide, methane, and CFC’s induce the __

  Greenhouse effect
• SC: One of the reasons for the increase of average temperature of the Earth is called __

  Global warming
• SC: One of the effects of global warming is __, we expect to have warmer dry seasons, stronger typhoons, and more precipitation

  Climate change
• Q: What is the percentage of greenhouse gases that human activities have added?

  A: 40%
• T or F, replace: Scientists expect that the next 20 to 100 years the world will cool a lot more

  A: F, warm
• Q: Give the top three carbon-producing countries in the world

  usa, china, russia
