So whats the problem?

• Lets summarize!

5
CO2 is the major culprit, but

• CH4 Methane
• N2O - Nitrous oxide
• PFCs Perfluorocarbons
• HFCs Hydrofluorocarbons
• SF6 - Sulphur hexafluoride
• time in atmosphere relative warming

Why are we worried about global climate change?

• Loss of habitat
• Extinction of species
• More bizarre weather events
• More heat deaths
• Climate shifts will affect agriculture
• Drought in some areas, fires
• Flooding in others
• Spread of diseases caused by insects or other
  organisms that survive better at warmer temps.
