Contributions To Biogeochemistry
Schlesigner is the author or coauthor of over 200 scientific papers on subjects of environmental chemistry and global change and the widely-adopted textbook Biogeochemistry: An analysis of global change (Academic Press, 2nd ed. 1997). He was among the first to quantify the amount of carbon held in soils globally, providing subsequent estimates of the role of soils and human impacts on forests and soils in global climate change.
He is a proponent of sound environmental policies and has testified before U.S. House and Senate committees. Environmental issues that he has advocated for include: preserving desert habitats, addressing global climate change, and carbon sequestration. His efforts have influenced tangible legislation such as the Clean Air Act, and California Desert Protection Act. His work has led to a better understanding of human impacts on the chemistry of the Earth’s surface, including an analysis of the sources and fate of industrial sources of nitrogen (e.g., fertilizer) in the natural environment.
