My research examines the interactions of terrestrial ecosystems with climate. This research integrates ecological, biogeochemical, hydrological, and atmospheric sciences to study terrestrial ecosystems, their responses to climate change, feedbacks that amplify or mitigate climate change, and human perturbations in land cover, land use, and ecosystem functions that alter climate. I specialize in the development of and experimentation with coupled models of Earth's biosphere, atmosphere, hydrosphere, and geosphere system.
Ecological Climatology, 2nd edition (Cambridge University Press, 2008)
Ecological Climatology introduces an interdisciplinary framework to understand the interaction between terrestrial ecosystems and climate change. Written for advanced undergraduate and graduate students studying ecology, environmental science, atmospheric science and geography, the textbook reviews basic meteorological, hydrological and ecological concepts to examine the physical, chemical and biological processes by which terrestrial ecosystems affect and are affected by climate.
Forests and Climate Change
In a review paper appearing in the 13 June 2008 special issue of Science magazine on "Forests in Flux," Gordon Bonan presents the current state of understanding for how forests impact global climate. "As politicians and the general public become more aware of climate change, there will be greater interest in legislative policies to mitigate global warming," said Bonan. "Forests have been proposed as a possible solution, so it is imperative that we understand fully how forests influence climate."
Nitrogen and Climate
In a 19 November 2010 Congressional Briefing on "The Role of Nitrogen in Global Change," sponsored by the American Meteorological Society, Gordon Bonan presents the current state of understanding for how human modifications of the nitrogen cycle affect climate.
The Ecological Theory of Climate Models
Models of Earth's land surface for climate simulation now represent the physics, chemistry, and biology of terrestrial ecosystems (both managed and unmanaged), the responsiveness of ecosystems to and their influence on atmospheric processes, and the pervasive influence of human activity on the biosphere. In the April 2010 issue of the iLEAPS Newsletter, Gordon Bonan outlines these ecological processes and their climate feedbacks in an article on The Ecological Theory of Climate Models. He was the guest editor for the November 2010 issue of the iLEAPS Newsletter on Terrestrial Feedbacks and Earth System Models. Key terrestrial forcings and feedbacks include biogeochemical cycles, anthropogenic land cover change, and their influence on climate change over the 20th and 21st centuries.

Linking Climate and Terrestrial Ecosystems
Kate Ravilious, contributing editor for environmentalresearchweb, writes about Gordon Bonan's research in a 7 June 2010 article Linking Climate and Terrestrial Ecosystems. "There is a good reason why summer clothes are often pastel shades - they reflect heat and help to keep you cool," Ravilious writes. "Exactly the same principle applies to the Earth, although our planet has more exotic clothes to choose from. Over the last couple of centuries mankind has drastically re-fashioned the Earth's surface and now this change in outfit is starting to affect the planet's climate."
William Henry Chapman, Mosby's Rangers
William Henry Chapman (April 17, 1840 - September 6, 1929) was second-in-command of John Singleton Mosby's famed "Mosby's Rangers" during the American Civil War. Learn more about Chapman's life story in The Edge of Mosby's Sword: The Life of Confederate Colonel William Henry Chapman. Published in 2009 by Southern Illinois University Press, Gordon Bonan's scholarly work is the definitive biography of Lt. Col. William H. Chapman.
