Global Climate essays

Global Climate essays The present situation of the global climate and more importantly the action taken to move toward safer environmental prospects is the issue in the sphere of climate change. However, in order to fully understand this topic a brief introduction of the sources of climate change, its subsequent effects and an explanation of why humans should be concerned is necessary. Only after considering that background, can present conditions and initiatives be comprehended to their full importance. Like that of a human, the temperature or climate of the world must be maintained at certain levels in order to sustain life. The Earths climate is a delicate balance between many natural and human forces. Solar energy, climate depends on this factor the most. Although one third of all solar energy is reflected back in space by the Earths upper atmosphere, the two-thirds that do penetrate the Earths atmosphere is the major proponent of weather. The atmosphere itself plays more of an ambiguous role. Cloud formation is a significant component of our atmosphere. It is known to shield solar rays yet still can be guilty of trapping heat in the atmosphere and yet sometimes is also found to let heat escape into space. However unpredictable the overall affect of the atmosphere on the Earths temperature, it does indeed affect it. What is certain about the atmospheres affect is the existence of heat trapping Green House Gases (GHGs), including water vapor, CO2, methane and nitrous oxi de that heat the Earths surface by blocking heats exit. The oceans, covering two thirds of the Earth are a key source of moisture and store heat efficiently as well as transport it across thousands of miles. Another key climate-affecting ocean issue is the carbon-dioxide consuming marine-life that relieves the atmosphere of huge amounts of CO2. The water cycle contributes a cooling effect by supplying water vapor that forms c...
