Climate Change, Global Warming, Renewable and Nuclear Energy Essay

Climate Change, Global Warming, Renewable and atomic Energy - Essay ExampleHowever, the recently experienced variation particularly in the stand out of world-wide temperatures is arguably not as a result of natural variation alone but to a fault the contribution of human activities. These activities are responsible for the heightened coulomb Dioxide levels and former(a) heat trapping gases. Carbon Dioxide (CO2) and other Green House Gases (GHGs) such as Methane (CH4), and Nitrous Oxide (N20), contribute to global warming through their young house military unit. These gases trap and retain the heat reflected from the earths surfaces, hence leading to extreme temperature rise (Turk & Bensel, 2011).The U.S. National Climatic Data Center indicates that global temperatures have been on the rise for the past triad centuries. The last century saw an middling rise in global temperatures of about 1.58 F with the polar warming twice as much (Turk & Bensel, 2011). The past 50 years da ta on unrelenting temperatures have indicated a significant rise in temperatures in other words, frosts, cold days and nights were slight whereas heat waves, hot days and nights were more prevalent (Turk & Bensel, 2011). Also, this warming has not been attributed to the earth alone but also the oceans which have for the past years absorbed most of the heat present in the atmosphere. As a result, the oceans temperatures have increased significantly too. With time, this heat (from the oceans) will be released back to the atmosphere and this skill result in further atmospheric warming. Currently, vast research suggests that global warming is ever increase due to the high concentration of green house gases within the atmosphere. The green house effect is experienced widely. In fact, scientists at NASAs Goddard Institute for Space Studies have established that thither is a administrate of absorption of suns energy than its emission. Hence, this imbalance is the chief cause of the gre en house effect (Pewclimate, 2011). The U.S. Global Change Research Program (USGCRP) produced a report in 2009 regarding the status of impacts of climate alteration in the U.S. According to it, human activities have greatly contributed to the rise in the concentration of the three of import green house gases Methane, Carbon Dioxide and Nitrous Oxide. Indeed, from the pre-industrial period these gases have increased in astonishing percentageages. Carbon Dioxide has increased by 40 percent Methane by 148 percent and Nitrous Oxide by 18 percent (Harding, 2007). Predictions indicate that with the current rate in increase of global temperature, 2050 will be devastating as the global average temperatures will exceed to almost 280 C. This will result in sudden and irreversible changes such as loss of the Amazon forest, vast melting of the Greenland cap, and release of Carbon dioxide from the soils (Turk & Bensel, 2011). Worse still, it is feared that smoke, hazes and specks emitted from the fogey fuel and vegetation could be currently mitigating global warming by acting as a cover which could be averting solar energy back to space. The current trend of cleaning up air pollution will eradicate this global dimming effect resulting in future increases in average global temperatures by almost 100 C (Turk & Bensel, 2011). Renewable Energy Recently, there has been a major(ip) concern to switch from using fossil fuels to the renewable forms of energy. However, to achieve this, we should take note of two things. First, there should be intensive research so as to offer alternative sources of energy in found to cut down on the prices of energies. Second, there is need for the energy prices to depict their true value in other words, these prices should reflect hidden costs such as the environmental costs which are conjugated to the
