4.14- Enhanced Greenhouse effect

Understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences
  • Pollution of carbon dioxide, methane and water vapour (greenhouse gases)
    • If their concentration increases then the Infra-red light would be increasingly re-emitted rather than escaping into space
    • This will raise the average global temperature which is called global warming
  • Consequences:
    • Raised sea levels- melting of icecaps
    • Changing ocean and wind currents
    • This leads to climate change
This will lead to the worlds Biome distribution changing, polarised caps melting, etc.
