  1. Greenhouse Effect Kate Tracey Grace Tita Amanda Richey

  2. What is it? • A naturally occurring and necessary process that warms the Earth.

  3. Why is the greenhouse effect necessary? • The gases trap in heat that the Earth’s inhabitants need to survive • Without the greenhouse gases the Earth would be 86 degrees Fahrenheit cooler at all times.

  4. Can it be a bad thing? • Yes… • Too many greenhouse gases can cause extra heat to be trapped within the Earth’s atmosphere. • This causes the Earth’s temperature to rise, which in turn, affects many other things.

  5. Average Global Temperature by Decade, 1880-2004

  6. What makes up the Earth’s Atmosphere? • 78% Nitrogen • 21% Oxygen • 1% Greenhouse Gases • Carbon Dioxide • Methane • Water Vapor • Ozone

  7. What are the natural sources of greenhouse gases? • Carbon Dioxide • Humans and Animals Breathing • Volcanoes • Methane • Cattles Digesting Food • Rice Fields • Ozone is naturally occurring

  8. What are the man-made sources of greenhouse gases? • Methane • Released from buried waste • Coal mining • Carbon Dioxide • Burning of coal, oil, and gas • Cutting down trees

  9. What things are affected? • The weather • Hotter summers • Possible temperature change year round • Water • Changes in rain fall patterns • Farming • Weather patterns affect crops • Sea Levels • Melting ice • Warmer oceans

  10. What can be done to slow down global warming? • Plant more trees • Recycle • Reduce man-made emissions • Solar Power • Hydro Power • Wind Power • Carpool, bike, walk • Use power carefully
