The Earths surface temperature has travel by about one head Fahrenheit in the agone century, with accelerated warming during the past three decades. on that point is stronger evidence and proof that closely of the warming over the kick the bucket fifty years is due to activities of merciful. Human activities charter changed the chemical composition of the cash machine and environs with the buildup of babys room vauntes, which atomic number 18 main cause of Global Warming. in that location are four steps in the glasshouse effect, which are, Ultraviolet rays from the sun, through space, to earth?s aura. The sun enters the atmosphere and hits Earth. Some of sunlight turns into heat energy in the abidance of infrared light. The heat gets impregnated by enclosing air and land, which in turn makes it hot. invisible rays that are remitted into the atmosphere are captured by greenhouse gases. The gas then absorbs the light and is sent support to the surface of Earth and warms it even more. According to the National academy of Sciences, the Earths surface temperature has uprise by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the brave out 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases ? primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping quality of these gases is undisputed although uncertainties be about exactly how earth?s climate responds to them.
