Green+House+Effect

The green house effect The sun creates energy in the form of solar radiation; the energy which reaches the earth is the short wave in the form of visible and ultraviolet light. Approximately a third of the energy from the sun is reflected back out from the earth. The rest of the energy is absorbed into the land and oceans. The green house gasses trap the energy and this warms the earth’s atmosphere. This is made up of 78% nitrogen, 21% oxygen and 1% other gasses. These gasses work together to create the natural green house effect which warms the earth to approximately 35oC.  When these there is variation in the quantity of gasses within the 1% other gasses this is when global warming occurs. It is thought by scientists based on extensive research that the increase in carbon dioxide is the stimulant for the increase in temperature for the globe.

As humans have the scientific methods to assess the climate history of the world it has been found that it is the carbon dioxide levels within the atmosphere that have controlled the drastic climate changes of the globe in the past. This has been found by ice core drills from Antarctica and Greenland. When the snow fell it compacted together to form ice but there were small air bubbles in the ice sheets, from these air bubbles the amount of carbon dioxide was analyzed, where it was found that the alteration in carbon dioxide caused dramatic changes to the earths temperature.
