4.14 Enhanced Greenhouse Effect



1) Pollution:
- molecules such as CO2, CH4 and water vapour (all Greenhouse gasses) = increase in concentration in their upper atmosphere
- consequences: The infra-red light from the planet surface will be increasingly re-emitted backwards towards the surface rather than escaping into deep space.
- consequences of this = raise the average global temperature = global warming
- consequences of global warming:

  • Melting of ice-caps in the polar regions = raise sea levels, Ocean currents changed, Change the way which winds are generated
  • Deserts would expand
  • Carnivorous forest distribution would change = Changes in the distribution of the worlds biomes to the major vegetation ecosystems
  • Climate change
