Change is inevitable in every part of the world. It is something that we cannot run away from or avoid. One thing that does not change is 'change' itself. One should consider the outcome of change, which could be positive or negative. Therefore, change is everywhere, regardless of how one looks at the environment. There have been changes in the political, economic, and socio-cultural beliefs of people all over the world; they are fundamental as they provide the basis of human existence. But today, what should be considered the most critical change is the one occurring in the Earth's climate system, and it is so significant as it affects the overall environment of man. The prominent and permanent feature of world climates today is change. This ranges from variability through fluctuations, trends, and abrupt to gradual changes due to alterations in the Earth-atmospheric energy balance. This study considers the structure of the atmosphere, components of the atmosphere, the solar source of the Earth’s energy, climate change, its effects, and adaptation strategies.
