  • The carbon cycle
    • It’s a natural process: What’s the problem?
  • Should we be concerned?
    • Three main reasons
  • What’s going to happen next?
    • Good Question
what are your concerns

  • East Anglia University(Climate Change Unit from where you can download actual data and plot your own graphs!)
climate models
Climate Models
  • EdGCM(Educational Global Circulation Model: Written by NASA scientists and pretty impressive. Runs on Mac or PCs)
  • Climate Prediction (Lots of information plus the chance to run a climate model on your PC as a screensaver)
  • The Hadley Centre (Met Office Centre for Climate Modelling: World leader in its field)
  • BBC News Story (Story about a new climate model)
ice and glaciers
Ice and Glaciers
  • World Glacier Monitoring Service(Lots of very technical data about glaciers)

  • Interesting article about surface temperature measurement (The 'Greening Earth Society' takes an interesting perspective on this debate which is distinctly American)
  • CO2 Science(Problem? What Problem?)
  • BBC News Story (About the important role of water vapour (humidity) in climate)
