Industrialization in the globe has led to increased production of greenhouse gases into the atmosphere (Mank, 2005). Still, deforestation, mainly due to human activities such as clearing forests for farming and settlement has also has also led to increased greenhouse gases in the earths atmosphere (Michaels, 2p004). Being less dense that air, these greenhouse gases such as carbon dioxide and other hydrocarbon gases have been established to rise up and form an impenetrable blanket in the earths atmosphere outer limits. This layer absorbs infrared radiation from the surface of the earth preventing it from escaping into space and emitting it back to the earths atmosphere thus increasing the earths atmospheric temperatures, a phenomenon otherwise known as the greenhouse effect (Mank, 2005).
Over the past several decades, the human community has experienced many unpredictable climate changes. Sea water levels are on the rise, either due to melting of polar ice caps or due to expansion of sea water as a result of increased temperatures on the earth surface (Johansen, 2002). Again, the world is experiencing extreme weather conditions such as droughts, flood, heat storms, and diminishing plant and animal populations. All these are attributed to global warming.
With greenhouse gases being the leading cause of global warming, man must be the main cause (Johansen, 2002). The world forest cover, responsible for absorbing carbon dioxide gas, has reduced by over 30 percent over the past two decades (Mank, 2005). Industrialization has been termed as a main economic activity over the past century. Therefore, with the unpredictable climate changes witnessed and the scientific evidence on their cause, global warming is a serious problem that must be address for the good of the present and future mankind generations.
