4.14 Enhanced Greenhouse effect

Key point:
The enhanced greenhouse effect is brought about my pollution, molecules such as CO2 H20 known as greenhouse gases, increase the concentration in the upper atmosphere and this causes the infra-red light would be remitted back to the surface, and this would raise the average global temperature. This is called global warming. An increase in the average temperature.
The consequences might include the melting of ice caps in the polar regions resulting in more water in the oceans, raised sea levels and this would change ocean currents and change winds and this start to contribute to the larger picture known as climate change. This would result in the redistribution of the worlds biomes, polar ice caps would melt, deserts would expand and distribution would change.
