ABSTRACT

Climate changes have been usually caused by major, long term variations in the key global weather conditions. Climate changes have often led to changes in the typical weather of a region over a long period. Climate changes have led to higher global temperatures and global warming. These have then led to more frequent climate- induced extreme weather incidents. The global greenhouse effect is usually defined as the process whereby the major greenhouse gases (GHG), such as water vapour, carbon dioxide and methane, have been impacting the earth’s climate and environment. Scientists have shown that climate change has been caused by human activities, which include rising global industrialisation, growing population, manufacturing and transport activities worldwide. One of the most serious climate change impacts is global warming. This is driven by the higher re-absorption and trapping of heat energies on earth by GHG emissions.
