Glabal 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 phenomenon 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.In one of his televised debates with Vice President Al Gore
"One of the main pieces of evidence global warming is based on is a rise in surface temperature over the last twenty years.” The evidence for global warming according to Justus and Fletcher is based on the temperatures from 1980 to 2000, with 12 of these years being the warmest years “since historical records have been kept.” While this may initially seem like significant evidence, closer analysis shows one major problem. The phrase “since historical records have been kept” suggests that these twenty years are being compared to a long length of time. However, in reality, “these temperature records only refer to around a century of data.” “The circulation of the ocean normally involves the sinking of cold water in higher latitudes and the replacement of that cold water with warm water from lower latitudes." This process “allows the inflow of warn surface currents that in turn warm the air above and held maintain relatively i
