Climate Change in my Life
Before know about climate change believed that this was only a synonym of global warming, however I realized that my colleagues, family and friends used inappropriately the term by ignoring its true concept, since the climate change refers to the global variation of the climate of the earth. For the United Nations Information Center (2015) is understood as climate change, a change of climate directly or indirectly attributed to human activity that alters the composition of the atmosphere and that affects the natural variability of climate, which can be observed over comparable time periods, i.e. how has evolved this phenomenon caused by the society.
Similarly, I did not understand the importance of addressing these issues in a matter of university students from various races, however as a result of filing this matter I note that at the moment this issue gains further momentum in the public sphere, the media, political activity and the scientific community or experts concerned about global warming and its impact on climate change.
It should be noted that at present the global warming and climate change are expressed in various ways in the biological cycles, behaviors of the ecosystems, etc. For example in a class we were talking about that great part of Antarctica and Greenland is surrounded by barriers of floating ice, that are being affected by the increase in the temperature of the sea, and adelgazándose quickly. These barriers make support for glaciers that cover these continents polar, however when these barriers disappear, melted by the rise in the temperature of the sea generated in turn by the global warming, glaciers increase their speed of fall and fall down into the sea, generating melting.
It should also be noted that in the field Current Issues taught me that human activities intensified the use of fossil fuels in the industrialization. In 1896 the Swedish scientist Svante Arrhenius was the first to proclaim that the fossil fuels could lead to or accelerate the warming of the earth. Established a relationship between concentrations of atmospheric carbon dioxide and temperature.
The transport, mining, deforestation, among others; the use these fossil fuels have made that accumulate carbon dioxide levels “had not been recorded in the earth from makes 200,000 years. They have also increased in the atmosphere considerable amounts of gases such as: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and chlorofluorocarbons (CFC’s), which form part of the phenomenon known as: The Greenhouse Effect. In the long term, these changes in the atmosphere would be translated into “an increase between 1 and 3.5 degrees centigrade in the average global temperature” land, same that will trigger significant changes in precipitation patterns: increase in the level of the sea, intensification of extreme temperatures in some regions of the planet, as well as an increase in the moisture from the air.
However, with the purpose of establishing common agreements, responsibilities and commitments for the mitigation and adaptation concepts learned in class that make reference to the reduction or coupling of these climatic phenomena, the international community established the United Nations Framework Convention on Climate Change, the result of which was the Kyoto Protocol (Japan 1997). In which a set of 39 developed countries and economies in transition, undertook to reduce its emissions of C02, establishing: (a) Limit the average global temperature to an increase well below 2C (3.6F) through the reduction of greenhouse gas emissions (Kinver, 2015). Every five years the countries will have a review in order to see its progress of reductions, b) You must change the way you do business: i.e. the way in which we produce consumer goods (McGrath, 2015).
Similarly before had ignorance about what in the present climate experts described and is climate change as a problem of stock and flow, refers to the fact that the greenhouse effect and climate change in turn depends on the concentration of greenhouse gases in the atmosphere which is the “stock”, while human beings are the ones responsible for the emissions of C02 which would be the “flow”. In the matter of Current Issues i also learned that the total amount of greenhouse gases in the atmosphere depends on the difference between emissions made by the man and the natural elimination of greenhouse gases from the air, above all by the oceans and plant life.
That is to say, the sun sends the solar rays to the earth, the same in turn impact against the surface of the planet, these are returned or sent outside the atmosphere toward the sun, this action is known as feedback by the response or reaction that has regard to solar radiation. The earth to be a hot mass surrounded by the cold of space, as all the masses emits radiation from the planet earth whose distribution of the frequency and intensity depend on the temperature of its surface, while more hot this land, the greater the flow of the energy radiated back to space, which produces a balance due to the incoming solar energy is heated with the ground until it is warm enough for the radiated energy go back to space.
In addition, solar rays when they come in contact with the surface of the earth, a percentage of its radiation remains in it this is known as stock. Because gas found in the atmosphere, by its composition, do not allow the energy radiated back to space. Similarly, us as human beings we must respect and take care of our planet as we have already seen and spoken these changes many irregularities in the world , such as we heard in the news that sometimes farmers lose their crops by heat or by the lack of rain , often called droughts and this in large part of the country and the world is reflected as well as in animals which are already some in danger of extinction by not having their habitat to which they were accustomed; we must therefore help not to contribute more in the air pollution for the welfare of the world and of ourselves in the future.
