Global Warming - Fact or Fiction
For many years now, the subject of global warming has been the cause of heated debates throughout the world. The theory is based on the idea that greenhouse gasses are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Debates have covered its causes and effects, and whether or not it actually exists and is a true threat to the planet. I, for one, do not believe that global warming is a real issue, but one created by environmentalists and scientists with a need for funding for additional and continuing research. I believe that research shows while there may be cyclical changes in temperature and weather on our planet, they occur naturally and not affected by man in any real way. One of the most popular theories being debated is the "greenhouse effect" which is caused by greenhouse gasses - naturally occurring gasses such as water vapor, methane, oxygen and carbon dioxide. As the Earth is a living planet, it is constantly undergoing change. Plate tectonics continue to change the face of the planet. The sea floor is still sp
It seems, however, that even the environmentalists have a hard time deciding if the Earth is warming up or cooling down. According to the NewScientist.com Greenhouse Timeline, it was during the 1800's that "greenhouse gasses" began to be studied and the idea of global warming was first introduced. But, during 1940 through the 1970's, worldwide cooling dampened scientific interest in the greenhouse effect. Some climatologists even predicted a new ice age. These and many other discrepancies have prompted the World Climate Report to develop a list of their top 10 fallacies about global warming and climate change. Some of the fallacies that they site are: In conclusion, when one takes all of the differing scientific evidence and interpretation into consideration, it would be very hard to agree with the theory "that artificial greenhouse gasses are causing unnatural global warming". I believe that it is too large of a leap for mankind to make to think that he can actually affect the global climate that has its own checks and balances and has been in the making for some 4 billion years. reading, and we still have earthquakes and volcanoes. Convection currents created by the tremendous heat and pressure at the core of the Earth move the plates. These processes release tremendous amounts of carbon dioxide and water vapor (greenhouse gasses). We know that these processes have been taking place since the beginning of time and, according to the geologic record, there have been numerous greenhouse and icehouse ages. Additionally, we know that the motion of the Earth, known as the Milankovitch cycles, also affect the Earth's atmosphere. These So in light of all this evidence, is global warming actually occurring? According to Accu-Weather, the world's leading commercial forecaster, "Global air temperatures as measured by land-based weather stations show an increase of about .45 degrees Celsius over the past century. This may be no more than normal climatic variation... [and] several biases in the data may be responsible for some of this increase". According to the Cooler Heads Coalition, a subgroup of the National Consumer Coalition, satellite data indicate a slight cooling in the climate in the last 18 years. These satellites
