An Outcome of Anthropogenic Factors

Changing weathers render portions of land both arid and foodless, creating food security threats. A growing population only aggravates the problem. The impact of climate change is thus extremely hazardous, and it becomes important to identify the root of this problem. Climate change is a direct product of global warming. As heat from the sun reaches the Earth, some of it is absorbed by the surface and the atmosphere, and the rest is reflected back into space. However, due to global warming, more and more of this heat is being trapped in the Earth’ s atmosphere, resulting in high temperatures.

The Earth’ s surface has warmed by more than 0.8 degree Celsius in the past century and almost by 0.6 degree Celsius in the 1970s-2000s [5]. The rise in temperature is attributable mainly to human activities which are termed anthropogenic factors. Global warming has increased over the years due to human activities of the burning of fossil fuels which release are harmful gases, deforestation and emission of chemicals. Other concerns are the use of gases such as Chlorofluorocarbons in refrigerators and aerosol sprays and the means of transport.

Most of this damage has occurred since 1750 after the heavy industrialization over the past three centuries. The impact was scientifically proven and presented by the Intergovernmental Panel for Climate Change (IPCC) in a series of reports. In 2007, the IPCC published its last assessment on the subject in which it asserted that human factors have in fact contributed widely to the resultant climate change. It is very likely that human factors are responsible for sea level rise, changing wind patterns, a risk of heat waves and droughts.

In fact, had it not been for the anthropogenic factors, the solar waves and volcanoes would more likely have cooled the Earth rather than warming it[6]. The IPCC incorporates into its findings the concept of “ radiative forcing” , a term which empirically measures the impact of each factor on the climate change.
