Outline The consequences of human interaction with the atmosphere and assess responses to these.
Driving, creating electricity, keeping food fresh and smelling good. These are all ways humans interact with the atmosphere. There are many other ways humans can interact with the atmosphere but I will talk mainly about how human interaction is creating holes in the ozone, how we have created the enhanced greenhouse effect and contributing to global warming.
The ozone is a thin layer of O3 that surrounds the earth and helps to regulate climate and temperature. Without the ozone there would be a lot more insolation and the earth would probably be too hot to populate.
Chlorofluorocarbons or CFC’s were used in refrigerators, air conditioners, aerosol cans and have also been used in fire fighting.
In September 16, 1987 a group of nations signed the Montreal Protocol to protect the ozone layer by phasing out the use of numerous substances believe to be responsible for ozone depletion.
Even with the work removing the CFC’s there was still, for some time, a hole in the ozone layer above Australia and New Zealand, and there is a large hole over Antarctica, increasing the possblity in skin cancers.
Today the use of CFC’s has greatly decreased so the ozone is getting better but industry and other pollution is still harming it.
Today there are basically no uses for CFC’s any more because of the phasing out.
The green house effect is the natural atmospheric occurrence. Before humans the ozone layer protected the earth from most insolation and would let in heat, it would then bounce of the earth and then most would leave the atmospere, leaving just a small bit while more comes in. These factors all contributed to keep the earth at the perfect temperature.
The green house effect has now been strengthened with the introduction of the human element. Burning fossil fuels in industry,...
