The carbon cycle and hurricanes in the United States between 1900 and 2011.

Hurricanes cause severe impacts on forest ecosystems in the United States. These events can substantially alter the carbon biogeochemical cycle at local to regional scales. We selected all tropical storms and more severe events that made U.

Forest cutting and impacts on carbon in the eastern United States.

Forest cutting is a major anthropogenic disturbance that affects forest carbon (C) storage and fluxes. Yet its characteristics and impacts on C cycling are poorly understood over large areas. Using recent annualized forest inventory data, we estimated cutting-related loss of live biomass in the eastern United States was 168 Tg C yr(-1) from 2002 to 2010 (with C loss per unit forest area of 1.
