Global Warming EssayThe global hundred motorcycle is one of the most important biogeochemical cycles in nature and should be considered with special emphasis because of constantly increasing atmospheric CO2 concentrations. Basically, the term global cytosine cycle describes the movement of all forms of carbon, which is the fourth abundant chemical element in our universe and essential for the structure and/or energy production for all(prenominal) living organism, between the atmosphere, oceans, biosphere and geosphere.Two main posts of the carbon cycle can be distinguished, i. e.the geological carbon cycle (with a turnover judgment of conviction in the range of millions of years), and the biological carbon cycle (which operates at time scales ranging between days and thousands of years). In short, in the geological cycle, processes like weathering and erosion are forming carbonates from atmospheric CO2 and water which are reacting with minerals in the earths surface and e ventually washed the into the oceans where they settle in sediments. The much faster carbon turnover in the biological cycle includes processes like photosynthesis and respiration, both key phenomena of life.2. A greenhouse gas is a gas in the atmosphere that allows sunshine enter the atmosphere and reach the earths surface, just now then prevents a certain portion of the reflected radiation (mainly this is the infrared or heat part of the spectrum) to leave the atmosphere towards open space again. Due to this install, a greenhouse effect, similar to that wanted and used in agricultural greenhouses to grow plants faster and to begin with due to warmer temperatures, develops and gradually heats up the atmosphere.This leads to global warming with all the negative effects discussed in the next paragraph. CO2 is both, a naturally occurring and man-made greenhouse gas, that together with other natural (water vapour, methane and nitrous oxide) and man-made substances (e. g. gases use d for aerosols and cooling liquids) is responsible for global warming, the man-made amount of atmospheric CO2 except alarmingly rising. 3.Global warming describes the slight, but constant and gradual elevation of our atmospheres temperature, especially realized as a man-made effect within the last decades. Although times of global warming have repeatedly occurred on our planet long before humans could contribute (e. g. ice-age and warming periods), the prominent increase of man-made atmospheric CO2 due to industrialization, excessive culture, and transportation leads, due to the previously described greenhouse effect, to a global rise in temperatures.With growing certainty that rise is understood to be responsible for an increasing occurrence of catastrophic events such as changes in weather (storms and hurricanes, heavy rain and snow, desertification), elevation of sea level (flooding), or melting of glaciers and arctic ice shelves. 4. There are diverse causes of global warming including natural processes such as carbon dioxide exhausting from rotting organic matter, atmospheric water vapour or natural gases like methane.However it is more and more go overd that the late dramatic increase in global warming is mainly caused by a man-made elevation in atmospheric CO2 by transportation, agriculture and industries. Such elevated concentrations of CO2 in the atmosphere and all their negative effects (see above) not only cause global warming by depend influence, but also interact with natural processes, altogether outbalancing the global carbon cycle and destabilizing our climate with unpredictable consequences. 5. The Kyoto Protocol has been signed by the United Nations on Dec.11th 1997 in Kyoto, Japan with the intention to set measures against progressive climate changes. For the first time in history, the participating nations (until today 136 nations signed and ratified the protocol) agree on threshold levels and the reduction of the production of greenh ouse gases within the protocols validation period from 2005 until 2012. 5. Unfortunately shaming poor. The United States signed the Kyoto protocol when it was initiated, but (together with Australia) never ratified the agreements.However, Australia stimulateed to ratify the agreements in the year 2007 after a change in their government, leaving the USA (who under President G. W. Bush shows no intention to ratify the contract in the near future) back in shame alone 6. Of course YES The US considers itself as one of the worlds leading nations. Doubtlessly it is one of the worlds leading industrial nations, which is good for wealth and progress, but also implies a big obligation, since due to its industry the US is also one of the leading producers of CO2.Thus, the US contributes a major part to the cosmopolitan greenhouse effect and therefore to global warming as well. So why does the US not act responsible in terms of environmental issues? Profit and industrial interests are a str ong power worldwide and very often refuse sustainable actions and environmental care, but in contrast to the US the other nations who signed the Kyoto Protocol at least hook on acting responsible.To my opinion it is a shame for the US to ignore alarming facts and signs of global warming and not even try to show some responsibility for our planet and future generations. So, even if the Kyoto Protocol is certainly not the final solution to growing environmental challenges, it is a beginning and can be the start of a sustainable and more responsible human future. However, to allow that beginning, cooperation and good will of all nations, including the US is essential.
