4.14 Enhanced Greenhouse effect

1. The greenhouse effect is brought about by pollution.
2. Molecules such as Carbon dioxide, water vapour, and methane are greenhouse gases.
3. The concentration of these gases reemit the infrared light back to earth instead of allowing it to escape into space. This raises the average global temperature. This is known as Global warming.
4. The consequences of global warming are the melting of ice caps in the polar regions, resulting in the rise of sea levels. This would change the ocean currents. It would also change the direction of the wind.
5. This would result in climate change.
6. Raising the average global temperature would change the distribution of the world's biomes (major vegetation ecosystems). Due to this deserts would expand
