Keith Smith is an Honorary Professor in the School of Geosciences at the University of Edinburgh. He has written extensively on climate change and was the Lead Author and Chair of the IPCC subgroup writing the chapter on Nitrous Oxide in the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.

'This timely book provides an excellent analysis of the key sources and sinks of the important greenhouse gas nitrous oxide, N2O, and of likely future trends in emissions and the prospects for mitigation. It will be a valuable source of information to audiences ranging from policy makers to professionals in climate change research and environmental science students.' James Galloway, Sidman P. Poole Professor, Dept. Environmental Sciences, University of Virginia, USA; winner of the 2008 Tyler Prize for Environmental Achievement
