Primarily, global warning is a matter that scientists can not stop for it increases everyday. First of all, the greenhouse effect is a huge disaster going on in this world that only a few take into consideration. "The actual greenhouse effect is a natural phenomenon, existing for eons before humans even appeared on the scene" (Salmon 25). Though the changes have been small they are expected to grow and speed up. "Warming occurs when various gases are trapped in the atmosphere and block the escape of the earth's radiation to space" (Edgerton 13). Because the extra gases are not allowed to expand, our summers feel like saunas and not like a cool 75 o F. Another characteristic of the greenhouse effect is its inability to brake down certain elements. One compound element that can not be broken down is carbon dioxide. "The only way to predict how much carbon dioxide will be released into the atmosphere in the decades ahead is to predict how much energy will be consumed- (Gribbin 119). The more CO2 man puts in the ozone the harder it will be to brake it down and release it into space. Furthermore, the greenhouse effect is the main reason why the earth continues to get hotter. According to Harold Bernard, "recent global temperature trends are a manifestation of the greenhouse effect" (13). Since carbon dioxide and methane are depleting the ozone layer, the sun's radiation is beating down on the earth. For instance, "[t]he year 1998 was the warmest since accurate records began in the nineteenth century- (Gribbin 7). Who knows, there will probably be warmer years to come? .
Moreover, there are many causes that increase the critical conditions of global warming. One major cause of global warming is the use of fossil fuels, which emit tons of CO2 into the atmosphere. "Carbon dioxide emissions into the Earth's atmosphere are causing warming trend [s]- (Mitchell 85) " due to fossil fuel burning.
