About book : The book 'GLOBAL WARMING & CLIMATE CHANGE' emphasis the major cause and process of global level warming. It explains how atmospheric chemical properties reacts with terrestrial rediation; creats reradiation and increases the global warming and also emphasis a broad classification of the atmospheric gases on the basis of their Thermo-Physical Properties (known as GHGs); Radiation Absorbing Capacity; Electromagnetic Properties (known as Ionized gases); Photo-chemical Properties (Photolysis and Photo-oxidation); Photo-synthesis Properties; Optical Properties (Reflection, Refraction, etc.) & Condansasion; Average Lifetime; Structure of Molecules mainly Linear molecules, Symmetric top molecules, Spherical symmetric top molecules and Asymmetric top molecules. The book elaborates a new view of atmospheric Heat Budget in reference to nature of atnospheric gases and their lifetime; Radiative Forcing and Global Warming Potential (GWPs). The book also provides a broad explainaton of causes of Ozone depletion createted global warming. Climatic Changes are elaborated in different forms of earth systems with their causes and effects on Biosphere. This book also provides a concise explanation of El Nino and La Nina.
