Understand how an increase in greenhouse gases results in an enhanced greenhouse effect & that this may lead to global warming & it's consequences.
The enhanced green house effect is whereby the greenhouse gases (carbon dioxide, methane, & CFC'S) are being released into the atmosphere at a far greater rate than would happen through natural processes and thus their concentrations are increasing ---> Climate Change/Global Warming (increase in average temps)
Consequences: Change in the worlds Biomes.
Example: Polar Regions (Arctic+Antarctica): melting of ice caps ---> raised sea levels --> change in winds + ocean currents. + Plants will die, & animal migrating patterns will change.
