In the industrial age, the atmosphere has been polluted by certain gases called Green House Gases (GHG). These gases allow the solar radiation of shorter wavelength to pass through downwards through the atmosphere heating the earth surface; but GHG do not allow the infrared radiation of longer wavelength emanated by the earth to pass through. Resultantly, the captured heat warms up the earth and the atmosphere. This phenomenon of warming is similar to induced heating in the horticultural Greenhouse where the heat is entrapped inside the glass walls of greenhouse. Thus the polluting gases in the atmosphere are called Green House Gases (GHG). The principal GHGs are carbon dioxide (CO2), methane (CH4), CFC (Chlorofluorocarbon) and nitrous oxide (N2O) etc.

Generally speaking, global temperature rise should affect the quality of rainfall, duration of rainfall and timing of rainfall, upsetting agricultural production schedule and even productivity, glacial melting and rise of sea level, occurrence of storm and possibly other geological and meteorological phenomena. But the effect of the global warming will not be uniform, some countries will have more rainfall and other countries will suffer from intense aridity and long-term fear of desertification.  Most of the nations will be losers in one way or the other and therefore the potential loser nations will wish to prevent global warming, which can be achieved mainly by reduction of emission of GHG.

In Part I, we introduce the fundamentals of the Climatic Science and Climatology. In Part II, we have highlighted the IPCC studies of anthropogenic global warming and climate change in some details. The Part III of the book studies the economics of climate change at basic level and the associated sociological impacts.

Climate change is a subject of global concern and hence will be of interest to a wider readership of policy makers, sociological and political professionals, scientists, economists, and students, researchers and teachers of universities and academic institutions. Though the book is not specifically designed for a university course, graduate students will find it highly useful for all environment science and sustainability programmes.

This book may serve as a sequel to author's two earlier books Renewable Energy and Water Resources – Strategic Overview for Global Sustainability of this publisher. There are two other books of this author on relevant subjects Sustainable Development – Environment, Energy and Water Resources (Ane Books, New Delhi/CRC Press US) and Green World Green Energy (Gyan Publishing House, New Delhi). The readers may find all of them as useful and relevant reading.
