=** TOPIC 5: Describe how climate can be influenced by human activities (eg. Greenhouse gasses, depletion of ozone layer) **=

=** We humans affect the environment. What are the causes of these environmental changes that are happening around the world? Cars are one of the main causes of this change in the environment. Cars use fossil fuels, when your car burns the fuel it release a gas called carbon dioxide. These gases have been breaking down our Ozone layer from carbon dioxide from the burning fossil fuels. It creates more green gases and a thicker atmosphere and it trap heat. That why it becomes more hot. The global temperate increased by 1 F past the 20th centuries. It is increasing 3 times faster on the century scale. Everyone has work, and the gas prices are over priced. This over use of natural resources is slowly hurting our environment. **= == = = =** The effects of global warming are, rising sea level temperature and the northern hemisphere snow as decreased. This increases of temperature will cause more precipitation, this will slowly break down the northern hemisphere and make the polar region warmer. These sudden changes in temperatures can mostly lead to areas that are dought meaning that there is no rain for a long period time. More tropical cyclones will occur, and it will be stronger and more intense. **=

=** Green house gasses is not really bad. It a good thing in a sense. Pretend if the sun die all of a sudden (of course it wont happen!) the plant would still be warm even if the airs is polluted. The only thing that we humans are worry about that the impossible things that might really happen. **=
