Cause and Effect of Global Warming
One of the hottest topics in the United States is the issue of global warming. This issue, once discounted and ridiculed as the wild imaginings of over enthusiastic environmentalists and "tree lovers," is now being taken seriously by scientists, politicians, business leaders, and the American environmentalist community. Environmental scientists have been trying to warn these groups that our continued use of coal and petroleum products, as well as established business practices such as dumping industrial wastes into the air and waterways, would be the cause of a natural phenomena called the greenhouse effect, or global warming. Now, when the earth's biosphere is obviously suffering adverse ecological effects from a century of carbon dioxide, nitrous oxide, and methane emissions, it is apparent to even the most skeptical anti-environmentalists that global warming is real. Effects such as El Nino and uncharacteristic seasonal changes are real occurrences in our lives.
Global warming is an ecological issue that has been caused by humans who overload the earth's natural ability to metabolize carbon, and the effect is that world temperatures and climate conditions are beginning to drastically change. An examination of the cause and effect of global warming show that this is an issue that cannot be ignored if the earth and its people are to survive.
How important is the issue of global warming in today's society? It is considered by most environmentalists to be the top priority item because if the problem persists, the earth will eventually be uninhabitable and all of the other problems of the human race will be moot. Phenomena such as El Nino are a direct consequence of global warming. Global warming is defined by The Concise Columbia Encyclopedia as a gradual increase of the temperature of earth's lower atmosphere as a result...
