4.14 - Enhanced Greenhouse effect



- Greenhouse effect caused by pollution - CO2, CH4, Water Vapour  (greenhouse gases) 
- The gases increase their concentration in the upper atmosphere 
- leads to the infrared light from the planet being increasingly reemitted back down towards the earths surface rather then escaping into space. 
- This raises the average global temperature = global warming. 


Consequences: 
- Melting of ice capes in the polar regions resulting in more water in the oceans so..
- Raised sea levels this would then change the.. 
- Ocean currents 
- Change the way wind is generated 
- All lead to the larger Picture = Climate Change. 
- Result in the change of the distribution of the worlds biomes
