Global Warming - Nonrenewable and Renewable Energy Sources

Climate Changes
Some possible effects of climate change resulting from a warmer earth are that the temperature rises. This temperature increase causes sea levels to rise due to the melting of ice sheets in the northern hemisphere and the slowing down of the ocean's circulation of warm water to the North Atlantic. This change in the sea level will eventually lead to once dry land to be covered, erosion of beaches, and coastal flooding. Other results of the climate change will be that the amount of rainfall increases, extreme weather events will happen such as hurricanes and typhoons, and there will be a rise in tropical diseases.

Ozone Depletion
Ozone depletion affects human health in that it causes humans to have more exposure to the sun's dangerous ultraviolet rays, which increases the possibility of developing either nonmelanoma or malignant melanoma skin cancer. With ozone depletion the rays are not as filtered as they are with normal ozone levels.

Ozone depletion affects crop yields in that the increased ultraviolet rays cause a decrease in crop productivity as the damaging ultraviolet rays cause changes in the growth of the crops, how the crops absorb the required nutrients to make them grow, and alters how the crop develops to maturity. Ozone depletion affects forest productivity in much the same way as crop productivity. The increase of the harmful ultraviolet rays causes a decrease in growth of trees and vegetation within the forest. It also increases the possibility of disease and affects the growth cycles of the forest life.

Ozone depletion affects materials such as plastics and paints because these materials have special additives added to them to protect them from normal solar ultraviolet rays. When more of the rays are let through due to the ozone layer being depleted, it causes these materials to breakdown faster and therefore, they do not last as long as they normally would outdoors.
