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 it's consequences.

Pollution: CO2, CH4, water vapour
these gases re-emit UV light back to the earth, raising the global temperature.

Consequences:
Melting ice caps -> raised sea level -> change in ocean current and wind direction -> redistribution of ecosystems -> less land due to increase of water
