Global Warning

1. Carbon Dioxide

   • Decomposing plant material
   • Rice paddy fields, cattle, coal mines

2. Water vapour

   • Evaporation from oceans, lakes and rivers
   • Burning hydrocarbon fuels

3. Methane

   • Decomposing plant material
   • Rice paddy fields, cattle, coal mines

4. greenhouse effect work

   • 1.Electromagnetic radiation at most wavelengths from the Sun passes through the Earth’s atmosphere
     • 2.The Earth absorbs electromagnetic radiation with short wavelengths and so warms up. Heat is radiated from the Earth as longer wavelength infrared radiation.
       • 3.Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere
         • 4.The atmosphere warms up
