  • It is predicted that the average temperature will rise another 3 to 10 degrees F in the next 100 years.

“Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace”

  • Global warming – the gradual temperature change in the Earth’s atmosphere due to primarily carbon dioxide build up from burning coal, oil and gas.

These are Greenhouse gases!

Greenhouse effect
  • Greenhouse gasses allow sun to enter the Earth.
  • Guess what! There is a lot more to the sun then just visible light!
where greenhouse gasses come from
Where greenhouse gasses come from
  • Plant and animal respiration ( we exhale carbon dioxide)
  • Driving cars
  • Heating and cooling a living space
  • Drinking from plastic water bottles
  • Forest losses
  • Eating non – local foods
insulators
Insulators
  • An insulator does not allow flow of electrons.
  • Insulation is a material or substance that is used to prevent the transfer of heat, electricity or sound. In a building, insulation is placed in the walls and roof. When insulating a building, the quality of an insulation material is measured by how well it keeps heat out.
