"Atmospheric Methane" is a specialized book that addresses the role of methane as a significant greenhouse gas. It highlights the alarming increases in methane concentrations in the atmosphere, which are now nearly three times higher than they were several centuries ago. The majority of atmospheric methane originates from human activities, including agriculture, coal mining, natural gas use, biomass burning, and livestock farming. The book provides a comprehensive analysis of the trends and causes of elevated methane levels and examines the impacts on the stratospheric ozone layer as well as the oxidizing capacity of the atmosphere. These insights are crucial for developing emission reduction strategies that can be part of a program to combat global warming. Edited by Mohammad A. K. Khalil, this work offers valuable scientific information for professionals and interested parties dealing with the challenges of climate change.
