GLOBAL WARMING, A FALLACY IN THE MAKING
For the last 20 years or so the subject of global warming has spawned heated debate among the world's brightest minds. Its causes and effects, if either actually exists, have been hotly debated. The most popular hypothesis is called the greenhouse effect with the agreed upon cause being green house gasses. These gasses are all naturally occurring and include water vapor, methane, oxygen, and the now infamous carbon dioxide. Greenhouse gasses exist in the atmosphere and have an effect on our global weather. They trap radiated heat and prevent it from exiting our atmosphere. This supposedly increases global temperatures and is, or will, cause melting of the polar ice caps. This in turn is expected to raise sea level and cause global coastal flooding.
A brief geology lesson
The world we live on is at least 4.6 billion years old. In that time span it has undergone immense changes. At one time most of the land surface was connected. The continents separated and migrated to their present positions. The force behind this is called plate tectonics. The sea floor is still spreading today and is the driving force for all of the earthquakes and volcanic activity that we experience today. Convection currents created by the tremendous heat and pressure of the inner core move the plates. This core is undergoing massive thermonuclear reactions. The heat produced migrates outward and the currents it produces move the plates. This process also releases enormous amounts of carbon dioxide and water vapor. This has been taking place since the Earth was formed. We know from geologic record that there have been numerous greenhouse and icehouse ages. The question is, is the greenhouse state caused by greenhouse gasses? Probably not, at least not entirely. There are several other factors involved - the most significant being the Milankovitch cycles. These are three cycles that describe the motion of the Earth...
