Atmospheric Methane - Its Role in the Global Environment
M A K Khalil
Methane is an important greenhouse gas that can contribute to climate
change. The present concentrations of methane are nearly three times higher
than several hundred years ago. Today, more than 60% of the atmospheric methane
comes from human activities, including rice agriculture, coal mining, natural
gas usage, biomass burning, and raising of cattle. Methane affects the
stratospheric ozone layer and the oxidizing capacity of the atmosphere, which
in turn control the concentrations of many man-made and natural gases in the
atmosphere. This book brings together our knowledge of the trends and the
causes behind the increased levels of methane. Based on the scientific
information on the sources and sinks, and the role of methane in climate
change, strategies to limit emissions can be designed as part of a program to
control future global warming. The contents are as follows:
