The debate on how much climate change is likely in the future is overshadowed by the still greater debate on what, if any, should be done to reduce or reverse global warming. How to tackle the consequences is another issue that is engaging the attention of environmentalists and policy makers across the world. HD Kumar's book is likely to increase appreciation of this phenomenon which is not limited to territorial boundaries of certain countries though political debates may make it look so. It makes an incisive analysis of what causes these changes and how.

The book is useful for students of climatology, geography, meteorology, global climate change and environmental science. Even lay readers of environmental issues will find the book extremely useful in understanding the problems facing mankind. Policy makers across the world will find the book useful in helping them take wise, balanced and informed decisions concerning present and future humanity living on the fragile and rapidly crowding greenhouse. Kumar tries to explain the issues, various international protocols and the jargons associated with this field of specialisation in simple and easily comprehensible expressions.
