Global Warming: Cause and Mitigation

Global warming is the gradual, but steady increase in heat on the earth’s surface and atmosphere that is caused by excessive greenhouse effect. This greenhouse effect is as a result of increased pollutants in the air, high levels of carbon dioxide as well as uncontrolled release of chlorofluorocarbons (CFCs) into the atmosphere. The sun releases short wavelength of ultraviolent rays. About 33.33% of this solar energy reaching the earth is reflected back to the space. This means that only 66.67% of this energy is absorbed into the atmosphere (Seinfeld & Pandis, 2012). The earth balances the absorbed energy by radiating equal amount of energy back into the space. However, since the earth is at a lower temperature compared with the sun, it radiates wavelengths that are much longer (infra-red).This is mainly thermal radiation from the land and vast oceans, which is absorbed and later radiated back to the surface of the earth causing the natural greenhouse effect. This natural greenhouse effect is the one that is responsible for ensuring that the life on earth is possible (Samimi & Zarinabadi, 2012).

Other than the natural greenhouse effect, which is necessary for sustainability of life on earth, human beings have taken up activities that intensify this greenhouse effect causing the undesired effect of global warming. Such activities include the indiscriminative cutting down of trees and clearing of vegetation as well as burning of fossil fuels. Scientists are in an agreement that most of the global warming experienced is from burning of coal and gas. This is because these activities cause greenhouse gases to build up in the atmosphere. When these gases build up in the atmosphere, they thicken the atmosphere preventing radiation of heat causing global warming. The most important gases that are as a result of human activities include carbon dioxide, methane, nitrogen oxide, Chlorofluorocarbons (CFCs) and water vapor (Ziska & Beggs, 2012).

            As a result of global warming resulting from human activities, climate change is inevitable. Burning of coal and deforestation alter the natural atmosphere leading to this change. Such activities on land lead to accumulation of carbon dioxide, especially in the tropic regions. Methane is released from human activities, such as rice farming and ranching. It is also released from burning of coal and on average; there has been an increase of 145% of methane concentration in the atmosphere due to human activities. Nitrogen Oxide is mainly released from industrial activities and some agricultural activities. Currently, it is 15% above the natural concentration. Chlorofluorocarbons (CFCs) are widely used in homes for activities, such as air conditioning and as solvents. These gases cause depletion of the ozone layer causing penetration of harmful gases into the earth’s surface. Therefore, human activities have been accredited to the current climate change. In the absence of such human activities, only the natural climate change would be experienced. This is caused by the revolution of the earth around the sun, which causes seasons. However, due to human interference, this natural phenomenon is modified, resulting in the anthropogenic climate change.

            Global warming is a phenomenon that is happening. Several evidences exist to support this matter. Scientists have come up with ways of proving that global warming is an actual phenomenon. Other than their empirical findings, such as plants and animals response to changes in seasons and redistribution of other species such as vertebrates towards the pole, other physical happenings evidence global warming. Such include:

Melting of glaciers – This is the significant and observable melting of the ice covering high mountains of the world. This melting is observable and can be explained by the reduction in the amount of the ice covering the mountaintops. For instance, according to Lonnie Thompson who is a geologist at Byrd Polar Research Center, the amount of ice lost in a week by Peruvian Andes glaciers is equal to the total amount that was previously lost in one year. According to him, one can actually sit and watch as the ice melts away.

Changes in rainfall patterns- This is experienced in most parts of the world. This is because the air is getting warmer meaning that there is a lot of evaporation from the land and the sea, and therefore increased precipitation. However, this precipitation is not evenly spread across all regions (Dai, 2011). There are places that get heavy down pours causing floods while other areas are exposed to long dry spells that wipe out vegetation, livestock, and human lives. Places experiencing such floods include the UK, which has experienced dangerous floods in the past eight years. According to BBC weather center, the amount of rainfall experienced in the UK in the year 2007 was at the highest since 1879. It was higher by 20% and caused many damages and affected many people. Other areas affected by such floods include China and Bangladesh (Dai, 2011).

Spread of diseases- Diseases such as malaria are known to dominate mainly in areas that are hot especially the tropic regions. The increase and spread of such diseases in the tropic regions and other areas is an indication that global warming is happening. These are the diseases that are related with precipitation, heat and humid; which are the ideal conditions for both tropical and sub-tropical regions (Dai, 2011). For instance, a mosquito-borne dengue fever, which was successfully wiped out of Florida Key, has re-established itself recently. This is a tropical disease, which is an evidence of the global warming that is happening. Other Areas experiencing such diseases include Burma and Singapore.

Due to the perceived dangers of global warming whose effects are already being felt, several mitigating factors have been put in place in order to control global warming. Most importantly, use of clean coal technology has been put in place in order to reduce the amount of harmful gases that are released into the atmosphere when coal is burnt. It entails chemically washing away of impurities in the coal as well as other minerals, using fuel efficient plants and using plants that use technologies that reduce emissions (Samimi & Zarinabadi, 2012).This strategy has been very effective is reducing the amount of emission hence reducing the rate of global warming. It has, therefore, received great support from the stakeholders such as the Environmental Protection Agency (EPA). In 2013, this agency issued a ban on all coal-fueled plants based on the permissible level of carbon emission. With low carbon emissions, global-warming related diseases and other disasters will be reduced. This means that funds that were previously directed into controlling such calamities will be used for more productive programs leading to growth in the economies.

            Another effective method for mitigating global warming is carbon taxation. This is where tax is imposed based on the level of gas emission, for instance, Greenhouse Gas Emissions. This tax is imposed on every ton of gas that is emitted into the atmosphere. In order to reduce the amount of tax that they pay, companies and individuals ensure a reduced amount of fuel consumption. It, therefore, works as a main incentive for decisions to use cleaner fuels and to adopt better and newer technologies that are line with environmental conservation strategies. This strategy also helps in reduction of cost of fuel since alternative sources of fuel are the renewable sources of energy such as the solar energy and biogas, which are cheaper and cleaner. This lowers the cost of production leading to growth and sustainability of the economy (McLure Jr, 2014).

Recommendations

Currently, most policies directed towards the issues of global warming place great emphasis on the issues of carbon emissions. However, there are other major factors that adversely contribute to global warming (Ziska & Beggs, 2012). One of them is the indiscriminative felling of trees as discussed earlier. In order to help mitigate this calamity, I would propose heavy fines on individuals and businesses that fell down trees. There have not been effective policies to deal with this issue within the existing policies. Even heavier fines should be imposed in countries where the forest cover of 10%recommended by the UN has not been met (Samimi & Zarinabadi, 2012).

This policy should also be designed to offer incentives to individuals, businesses, and countries that are at the fore front in ensuring massive planting of trees as well as taking other measures to ensure environmental conservation. This will ensure a global combined effort in mitigating global warming since in terms of effects of pollution the world is just a small village. This means that carbon emission in Japan will affect the dwellers of the interior of Africa.
