Greenhouse gases have the capability to trap heat and emit radiation within thermal infrared range. Carbon dioxide, nitrous oxide, methane and water vapor are some of the primary greenhouse gases present in our atmosphere. The concentration of greenhouse gases has increased considerably since industrialization. Due to their tendency of absorption and emission of heat in the earth's atmosphere, they tend to be responsible for melting glaciers, seasonal variations, changing weather patterns and ever increasing average global temperatures. This book consists of contributions made by international experts. It attempts to understand the multiple branches that fall under this discipline and how such concepts have practical applications. Also included in this book is a detailed explanation of the diverse aspects related to greenhouse gases. It will serve as a reference to a broad spectrum of readers.
