In recognition of the all-pervasive role global warming - and the related phenomena of ozone hole, ocean acidification, and acid rain - are set to play in the affairs of the world, these topics have been given a strong emphasis in the undergraduate and graduate degree courses all over the world. This book is one of the outcomes of the authors' curriculum-development efforts on the subject of global warming. Besides giving a comprehensive coverage to the general state-of-the-art, the book specifically dwells upon the highly debated issue of the contribution of wetlands to global warming. Besides students the book will be invaluable for teachers, researchers, industrial professionals, and all those who have stakes in global warming control.
