Presentation Transcript

  1. Science Starter At night the moon is -387F, and during the day it is 253F. Why do you think temperatures are so much more extreme on the moon than on earth?

  2. Agenda • Science Starter • What is Global Warming? • Global Warming Effects • Climate Change Prediction Group Work • Global Warming Foldable • Exit Ticket

  3. Lesson Essential Question How do human activities impact global climate change?

  4. NPR-National Geographic Global Warming Video • http://www.npr.org/news/specials/climate/video/ • Part 1, 4 and 5

  5. Think about it… In the summer, why does the inside of a car get very hot when it is sitting in the sun? • The heat from the sun goes into the car. The windows on the car trap the heat inside. This makes the inside of the car heat up

  6. GREENHOUSE EFFECT When incoming solar radiation (heat) is absorbed by gases in the atmosphere. (Just like the windows in a car trap heat, the gasses in the atmosphere trap heat.) Without the atmosphere, earth would be 59 F colder!

  7. GREENHOUSE EFFECT • What traps the heat? • Water vapor (H2O) • Carbon dioxide (CO2) • Nitrous oxide (N2O) • Methane (CH4) • These are called “greenhouse gases.” • The more greenhouse gases in the troposphere, the warmer our planet gets.

  8. methane Nitrous oxide CO2 water vapor

  9. Climate Change Reading: • As you read the article, ANNOTATE: Underline important phrases Circle key terms Exclamation point or star in margins of important sections * !

  11. Rising Sea Levels • https://www.youtube.com/watch?v=-xLokKVdk7I

  12. SO CLEARLY… • Climate change affects different places in different ways • IN A GROUP, you are to: • Read the description of your country • Answer the questions about how climate change will specifically affect your country

  13. Foldable - outside Global warming

  14. Foldable - inside

  15. EXIT Ticket • 1. Which greenhouse gas is the most abundant in our atmosphere? • Oxygen b. Carbon Dioxide c. Nitrous Oxide d. Methane • 2. Which of the following has caused the greatest increase in global warming? • a. Burning of fossil fuels c. People breathing out • b. Increases in atmospheric nitrogen d. Turning lights off • 3. The burning of fossil fuels is causing an increase in the following: • Atmospheric nitrogen b. Atmospheric oxygen c. Atmospheric carbon dioxide d. Atmospheric phosphate • 4. What is the main source of methane in our atmosphere: • a. Chemical manufacturing c. Cow flatulence and feedlots • b. Cutting down trees d. humans exhaling

  16. Foldable - inside

  17. Greenhouse gases • Carbon Dioxide (CO2) • Emitted through burning fossil fuels • Methane (CH4) • Emitted during production of fossil fuels • Nitrous Oxide (N2O) • Emitted during farming and industrial activities • F-gases • Ex: hydrofluorocarbons • Emitted during industrial processes How are greenhouse gases emitted into the atmosphere?

  18. How is agriculture affected by climate change? • In the long run, climactic change would affect agriculture in many ways • Lower quality/quantity of crops • Agricultural practices like fertilizers and insecticides • Soil drainage and erosion • Reduction of crop diversity • Less competition among organisms

  19. How is species diversity affected by climate change? • Species that depend on one another may become out of sync. • For example, plants could bloom earlier than their pollinating insects become active

  20. How is ecosystem balance affected by climate change? Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Ex: Polar Bears • Discovery ed: The Impact of Climate Change on Polar Bears

  21. How are oceans impacted by climate change? Ocean Acidification: The ongoing decrease in the pH of the Earth's oceans caused by the uptake of CO2 from the atmosphere. A more acidic ocean could wipe out species, disrupt the food web and impact fishing and tourism.

  22. How are sea levels impacted by climate change? • Higher temperatures cause ice to melt • Water absorbs more heat than ice so temperatures will continue to rise • This causes shoreline erosion and coastal flooding • http://www.youtube.com/watch?v=-xLokKVdk7I

  23. How are weather patterns changed by climate change? More intense heat waves and droughts in some region and fewer events in other places are predicted.
