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 spreading, and we still have earthquakes and volcanoes. Convection cur

2. Model forecasts are correct, but confounded by sulfates, volcanoes, etc. They feel it is convenient to blame climate model errors on rare events such as volcanoes, El Nino, solar flares, etc. They state that models do not do a good job of handling rudimentary atmospheric variables such as temperature, precipitation and wind.

Other fallacies sited are: In the United States, recent years have been the warmest on record; northern hemisphere temperature increases over the last century correspond to human-induced warming; more CO2 yields much higher surface temperatures; climate models are correct but are limited by computer technology; the climate will be more extreme; and, summers will be extremely hot and dry. None of these theories have been proven by any scientific data that is available to date.

As for the man-made greenhouse gasses, according to many environmentalists and the EPA, since the beginning of the industrial revolution atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15% . These increases have enhanced the heat-trapping capabilities of the Earth’s atmosphere. Sulfate aerosols cool the atmosphere by reflecting light back into space; however, sulfates are short-lived and vary regionally. Some scientists believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. The Committee on the Science of Climate Change states that temperatures are, indeed, rising with the global mean surface air temperature warmed by about 0.4-0.8°C during the 20th century. The Committee also states that the changes observed over the last several decades are “likely mostly due to human activities, but the Committee cannot rule out that some significant part of these changes are also reflections of natural variability”. This committee believes that human-induced warming and associated sea level rises are expected to continue through the 21st century. The secondary effects they expect include increases in r
