Global Temperature example essay topic

Global Warming The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO 2), and methane, which come naturally, mainly from animal manure. Other gases like nitrogen oxide and chlorofluorocarbons; man made gases, get caught in the atmosphere as well, also the decay of animals and respiration are two main natural sources of carbon dioxide. In my opinion, the people of the world should try to slow down the emission of man maid greenhouse gases and find ways to restore the natural balance so the climate does not change in an unnatural way. If we fail to do this, we will be forced to adapt to a new and uncertain climate.

If we had an international cooperation to put a damper on the production of chlorofluorocarbons and slowed down the use of fossil fuels it would dramatically slow done the process of global warming. Carbon dioxide pollution from the increase of industry and transportation is a major cause of global warming. These two causes are connected with the growth in the world population. As the population grows the necessity for food and other products increase, therefore industry must grow to keep up with the demand. The increase in transportation is directly due to the growing population and the need for jobs and the growing congestion on our highways.

Another cause in global warming is deforestation. Trees remove carbon dioxide from the air as they grow. The carbon dioxide is released back into the air as they are cut and burned. The forest ability to reduce the carbon dioxide from the atmosphere is decreasing rapidly due to massive deforestation of worlds rain forests. These causes are fixable, but if they are not fixed, the Earth and its inhabitants will become victims of global warming. Over the last hundred years, the global temperatures have been increasing slowly, but steadily.

Since 1980, the average global temperature has risen 0.2 degrees Celsius (0.4 degrees Fahrenheit) each decade. Scientist predict that if we continue putting the same amount of green house gases into the atmosphere, that by the year 2030 the temperature will be rising as much as 0.5 degrees C (0.9 degrees Fahrenheit) or more per decade. Overall, the global temperature could rise anywhere from 5 to 9 degrees over the next fifty years. If the temperatures do rise, as predicted, several things could happen. The increase of temperature could alter the growth of crops in areas near the equator due to insufficient rain and heat.

The loss of the ability to grow crops would inflict serious economic damages to un industrialized, third world countries that rely on agriculture as a major source income. With the high temperatures polar ice caps would melt and cause the sea level rise 1 to 3 feet. This would destroy small islands, coastal cities and some shallow rivers. The Florida Everglades, and costal cities, such as New York City and Miami would be destroyed.

I believe global warming is a big threat to our nation and the world. If we do not act now, it may be too late. Although there is no sure way of telling what the climate will be like in the future we must take steps to ensure the health of the Earth. If you look at what is happening to this world, and you will see that there is a pollution problem. There are steps being taken to reduce the amount of green house gases put into the air, but it still is not enough, we need to do more to reduce global warming, if we don't future generations will suffer the effects of global warming.
