Climate change is a hard reality and changing weather patterns, retreating glaciers, polar ice melt, sea level rise, increased severity and occurrence of natural disasters like flood, super cyclone, drought, changes in hydrological cycles, crisis in freshwater and drinking water resources, uncertainty in cereal output, increasing vector borne diseases, changing migration pattern and flowering time, are just some of the consequences already being experienced by us. Fragile and delicate ecosystems like coral reefs and mangroves are extremely sensitive to the slightest variation in climate. In developing countries like India, climate change may contribute an additional burden on ecological and socioeconomic systems associated with rapid urbanization, industrialization and economic development. Climate Change : Man and Environment is an attempt to compile various aspects of climate change, its causes and impacts on different facets of life and environment. Mass awareness and technical understanding of the cause and impacts of climate change is necessary to adopt necessary mitigation/adaptation strategies to ensure out own existence. The present compilation is enriched with 25 lead articles contributed by the authorities in their respective fields and is meant to serve as an important resource material for students (both undergraduate and postgraduate), researchers, academicians, naturalists, environmental and wildlife activists as well as for common people having concern for nature and environment.
