Nano particles present in the atmosphere plays a major role in global warming and in radiation budget of our earth. Nano particles can have significant environmental consequences and further knowledge is required to evaluate their long-term effects on the atmosphere and living organisms. This book has broad information of atmospheric nano particles and its influence on earth's climate system. Information from various national and international organizations were also synthesized and given as table and pictures. It helps to find new area of research work.

Todays energy system is dependent only on hydrocarbons, especially oil, but increasingly also natural gas. Eighty per cent of the current global energy supply is of fossil origin.Gas hydrates (clathrates) are ice-like compounds in which gas molecules are held in crystalline cages formed by water molecules. They are widespread in areas of permafrost and in the continental margins where pressure and temperature conditions are appropriate for their formation. Methane hydrates are an energy source of potentially staggering magnitude compared with other known hydrocarbon deposits. This type of...
