5. The Greenhouse Effect
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere trap heat from the Sun’s rays.
Greenhouses work by trapping heat from the sun.
The glass panels of the greenhouse let in light but keep heat from escaping.

7. Without the greenhouse effect, the Earth would not be warm enough for humans to live.
As the greenhouse effect becomes stronger, it continues to make the Earth warmer than usual.

8. Let’s Check out the Data...

9. Causes of Global Climate Change..
Increase in CO2 (carbon dioxide), CH4 (methane), O3 (ozone) (from burning of fossil fuels, release of ChloroFluoroCarbons)
Increase in the Greenhouse Effect (Earth’s natural heating process - gases in atmosphere trap heat (like a car window)

10. Effects...
NASA: Effects of Global Climate Change

11. Effects of Global Climate Change..
Raising sea levels  Flooding
Melting of Glaciers, Arctic shrinkage
Altered patterns of agriculture
Increase extreme weather (ex. hurricanes)
Increased evaporation ( greater rainfall and erosion  deforestation)
Expansion of tropical diseases (ex. Malaria)
Changes in timing of seasonal patterns in ecosystems
Acidification of Oceans
Increase respiratory & cardiovascular diseases
