Climate Change Analysis
Although everyone has heard about the global warming as the result of greenhouse effect and CO2 emission, no one believes it enough to start taking actions. The reason of populace’s unwillingness to accept the fact of the rapid climate change is hidden deeply in our psychology. Mostly, people do not pay attention to the changes that occur during the years, because every day the change is so inconspicuous that it is almost impossible to see or feel it without special equipment. Another problem is that people do not think about the life after them, in fifty, or eighty years later, as by that time they will not be alive nothing will matter for them. In a word: it is egoism.
CO2 and the Food Chain
In order to affect the living creatures and the food chain directly, CO2 concentration in the atmosphere must reach the level of 3%, which is 30 000 ppm. Now, it is 395.55 ppm. (Tans, n.d., p. 1), but indirect effect is observed even today. Marine food chain suffers the most. Every day, world’s ocean absorbs 6 million tons of carbon from the air, which turns the water into acid that is extremely dangerous for marine creatures. In some regions, corrosive level will be reached within ten years. At that stage, the water will dissolve the shells of mussels and other seashells causing disruption in the food chain (McKie, October 4, 2009).
Considering the idea of cycling matter, what enters the air should come back to the soil and so on. Though, this rule is not proper, especially in relation with CO2. The idea of positive feedback suggests that the outcome of the system will change the system’s reaction to the income, what is happening today. The amount of carbon stored in peatlands is about 400 gigatonnes, and every day this carbon is dissolved in water courses, which finally enter the oceans where carbon transforms into CO2 gas. Such process is the positive feedback for global warming (Freeman, Ostle, Kang, 2001, p 149), as the temperature rises causing the ice melting. It increases the amount of water including the water courses, which then absorbs more carbon and releases it into the atmosphere changing the reaction of the system.
The idea of negative feedback assumes that system’s outcome does not change its reaction to the income but stabilizes it. The example of such stabilization is provided by National Academies. The amount of CO2 increases slightly raising surface temperature. It increases the amount of water evaporated from the oceans, seas, and rivers, thus, more low clouds appear. Regarding the structure, clouds reflect the major part of sunlight, which is reflected back into space including the infra-red spectrum responsible for heating. The “positive feedback” model assumes enhancing the greenhouse effect due to the water vapor. With the reduced amount of heat, surface temperature slightly decreases stabilizing the overall temperature (National Academy of Sciences, 2008).
Stages of Climate Change Denial
Despite the great amount of climate change confirmations, there are a lot of people who disagree with this obvious fact. Michael Mann (2012) says that this opinion was financed and fabricated. Climate denial movement or “Serengeti strategy” isolates individual scientists and flings reckless charges of fraud or incompetence in the attempt to discredit climate science in general: with the ultimate goal being distraction from the realities of climate change (Cook, February 9, 2012). They decline the fact that anthropogenic factors affect the climate so much that they cause global change in climatic systems of the Earth. This difference has formed two struggling fronts in climate change.
One of the possible mitigations of CO2 problem and global warming is trees planting. Such plan has certain advantages arising from the basic chemical reaction, which is essential part of tree’s life. Photosynthesis is the reaction, which transforms carbon dioxide into oxygen under the effect of sunlight. The more trees we plant, the higher oxygen emission is. By planting billion of trees we will reduce the concentration of the CO2 in the atmosphere, and increase the concentration of O2, which will affect the whole planet positively. It is much easier to plant trees than to reorganize the emission systems at the factories, and reduce the number of automobiles. The advantages are weighty; but how can we provide this if deforestation of our planet is spreading so widely? Another question refers to the place. In order to plant such amount of trees we need much space, but expansion of cities will not let this happen.
