For the past 100 years scientists have been warning people of climate change. The general opinion has flip-flopped about three times, from cooling to warming to cooling, and back to warming again. The fact is that earth's climate is constantly changing. It has periods of cooling and periods of warming. However, studies have shown that short-term temperature change cannot be used as a gauge for future predictions. The fact that the earth has experienced warming throughout the last century is not proof that the industrialization of humans was the cause. If we want to even try to predict what the climate will do in the future, we must look back over a longer time interval. The recent global warming is not a result of human activity, but of natural causes.
97 percent of carbon dioxide in the earth's atmosphere comes from nature, not from man. Volcanoes, swamps, rice paddies, fallen leaves, and even insects and bacteria produce carbon dioxide, as well as methane. According to the journal Science(Nov. 5, 1982), termites alone emit ten times more carbon dioxide than all the factories and automobiles in the world. Natural wetlands emit more greenhouse gases than all human activities combined. (If greenhouse warming is such a problem, why are we trying to save all the wetlands?)
The earth's climate has run on a fairly clear pattern over the last 700,000 years. Throughout this time period, there have been a series of glaciation cycles lasting around 100,000 years each. The cycle begins with 90,000 years of cooling, known as an ice age, followed by 10,000 to 12,000 years of interglacial warming. The average temperature of the last ice age we had reached about 9 to 12.6 degrees Fahrenheit cooler than it is today at its lowest point. This peak took place around 18,000 to 20,000 years ago. We are currently in an interglacial warm period that began 10,700 years ago.
Within the last 1,000 years the earth has been through much warmer temperatures than what we are dealing with today. A report from the National Academy of Sciences affirmed the existence of a Medieval Warm Period from about 900 A.D. to 1300 A.D. During this period, the temperature rose by more than 1° F to an average of 60° or 61° F, as much as 2° F warmer than today.
Within the last 150 years the earth has experienced a period of irregularly cool temperatures. The same National Academy of Sciences report that affirmed the existence of the Medieval Warm Period also affirmed the reality of what is known as the Little Ice Age. During the Little Ice Age, which lasted from about 1500 to 1850, global temperatures plummeted. In the summer of 1816, temperatures were recorded in Connecticut to be 2.5 degrees Celsius colder than the average of 1780 to 1968. Temperature differences such as these appeared around the world. This was a period when the average life expectancy for the Vikings in Greenland was 10 years because of the harsh conditions and lack of crops. People in Europe...
