Global warming: A threat to life
Planet earth is facing a serious crisis in the form of global warming. Citizens of earth no matter wherever they are living, all are equally affected. Global warming is showing its “Ecosigns” (Achenback and Heidi 1) such as changing monsoon pattern, expanding arid regions, fluctuating seasons, decreasing fresh water, and rising sea levels. The world is often divided about the reasons of global warming, as some believes that it is a publicity stunt (Horgan), whereas others link it to anthropogenic actions. The global warming and the resultant climatic changes are due to uncontrolled human exploitation of earth, and its resources thereby emitting large volume of greenhouse gases into the atmosphere. The greenhouse gases forms a layer around the earth’s atmosphere, trapping and reflecting the sunlight back into the earth’s surface thereby increasing the atmospheric temperature. In addition, greenhouse gases have the capability to damage the ozone layer that protects the earth from harmful ultraviolet rays.
The Intergovernmental Panel on Climate Change (IPCC), a scientific body established in 1988 by the United Nations Environmental Program (UNEP) and the World Meteorological Organization (WMO), studied about reasons of climate change. The IPCC’s assessment report found that carbon dioxide, methane, nitrous oxide, hydro fluoro carbons and fluorinated compounds which are of anthropogenic origin, are the major greenhouse gases that cause global…
