greenhouse effect news
GREENHOUSE EFFECT – NEWS?

  • It is what makes life on earth possible…
  • …and it’s the reason that the surface of Venus is hotter than the surface of Mercury
  • BUT the bad news is that human activities have exceeded the capacity of natural systems to maintain a balance and GHG concentrations in the atmosphere are rising
for a 30 chance of avoiding dangerous climate change
For a 30% chance of avoiding dangerous climate change
  • Global figure of 450 ppmv CO2
  • This implies a UK carbon budget of 4.8 Gt C for 2000 – 2050
  • But 1.2 Gt C have already been emitted from 2000 – 2006

Education – the call to arms
  • Schools have a vital role to play in changing behaviours – not just of tomorrow’s citizens but by exporting messages to families and communities now
  • Ultimately we need a new value set and a new economic paradigm to live by
  • Our best chance of achieving this is through our young people
  • By building sustainable schools we can help build a sustainable world
