ABSTRACT
Global warming is the rising average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Many studies have pointed out that human activities have contributed to a number of the observed changes in the climate. This contribution has principally been through the burning of fossil fuels, which has led to an increase in the concentration of GHG in the atmosphere. It is an issue to avoid the critical situation caused by the rapid change of climate and to secure sustainability.
