Greenhouse gas mitigation potential in U.S. forestry and agriculture

This technical report examines different future scenarios for sequestering carbon and reducing emissions of methane (CH4) and nitrous oxide (N2O) from U.S. forestry and agriculture. Net greenhouse gas mitigation estimates in response to carbon price assumptions are presented for…

Estimating combustion of large downed woody debris from residual white ash

The production of residual white ash patches within wildfires represents near-complete combustion of the available fuel and releases a considerable quantity of gases to the atmosphere. These patches are generally produced from combustion of large downed woody debris (LDWD) such…

Influences of boreal fire emissions on Northern Hemisphere atmospheric carbon and carbon monoxide

There were large interannual variations in burned area in the boreal region (ranging between 3.0 and 23.6x106 ha yr-1) for the period of 1992 and 1995-2003 which resulted in corresponding variations in total carbon and carbon monoxide emissions. We estimated a range of carbon…

CO2 emissions from wildfires in the U.S.: present status and future trends

From introduction: Wildfire is a majoar natural disaster in the United States. In 2002, for example, tens of thousands of wildfires occurred that consumed nearly seven million acres of forest and other land cover (NIFC, 2003). Wildfires contribute to increasing atmospheric CO2…
