Climate change is a phenomenon that takes place due to the changes in Earth's climate system. It occurs when new weather patterns are formed in earth's climate that last for few decades or maybe for millions of years. There are five interacting parts that constitute in climate change, the atmosphere, hydrosphere, biosphere, lithosphere and cryosphere. Earth's energy budget is determined by the balance of incoming and outgoing energy, and the passage of the energy via climate system. The factors that affect climate changes are cyclical ocean patterns, external forcing, human activities, etc. The actions that are used to limit the magnitude of long term global warming and its related affects fall under climate change mitigation. It is concerned with the reduction of greenhouse gases caused by human emissions. This book provides comprehensive insights into the field of climate change. It also unravels the recent studies in the field of climate change, its challenges and solutions. This book is a vital tool for all researching and studying this field.
