Abstract
global warming is recognized by scientists and most world governments as a major climate event that is currently happening. There has been much debate about its causes, which come from many factors and not all of which are known. Several major contributing factors have been identified, however. It is thought that global warming as we are presently experiencing it is due mainly to four things: an increase of greenhouse gases from man-made sources, man-made ecological changes, climate feedback loops, and solar radiation. The "greenhouse" effect is what happens when infrared radiation is absorbed by the atmosphere which in turn warms a planet's lower atmosphere and surface. The effect was discovered in 1824 by Joseph Fourier and how it works is well established as a science fact (IPCC 2007).
