2.14

understand how an increase in greenhouse gases results in an enhanced greenhouse effect that may lead to global warming and it's consequences

pollution molecules are; carbon dioxide, methane, suplhur dioxide, nitrous dioxide, water vapour

these gases increase in concentration in the upper atmosphere, which raises the average global temperature (global warming)
simple ideas of the consequences are
*melting ice caps
*raised sea levels
*ocean currents changing
*winds generated elsewhere
this contributes to CLIMATE CHANGE
which changes the distribution of the worlds biomas. ecosystems
polar ice cap melt, forest distribution changes, deserts expand.

  1. well done, just to emphasis the absorption of UV light and it redistribution/ emission as IR radiation which raises the average KE (temperature).
