4.14 Enhanced Greenhouse effect

Enhance of greenhouse effect -> produce by pollution ( carbon dioxide, Methane, water vapour). These gasses Increased in their concentration in the upper atmosphere.


Consequences are that infra-red light re-emitted backward to earth. This raise the average global temperature = GLOBAL WARMING. 


Diagram showing the process.
Red = Infra-red light 

Consequences of global warming 

• Melting Ice caps
• Raised Sealevels
• Ocean current
• Winds
• Climate change
