Climate change refers to the changes in the statistical properties of climate system. The term is used to refer to anthropogenic climate changes, also known as global warming. Climate change includes both global warming as well as its effects such as precipitation that differs from one region to another. Global warming refers to the increase in average temperature of the earth's surface and the increased levels of greenhouse gases such as carbon dioxide, methane and nitrous oxide. The dominant cause of climate change is human activities like excessive emission from fossil fuel combustion such as coal, petroleum, diesel, natural gas, etc., carbon dioxide released by cement manufacture and deforestation. Alleviation of climate change includes the reduction of greenhouse gas release, the use of renewable energy, nuclear energy, enhancement of carbon sinks through reforestation. This book unravels the recent studies on climate change, and its impacts. It elucidates new management techniques and their applications in a multidisciplinary manner. This book will provide comprehensive knowledge to the readers.
