USGS - science for a changing world


There is compelling evidence that observed changes in global climate are associated with radiative forcing from increased concentrations of atmospheric greenhouse gases (GHG). Anthropogenic activities such as the burning of fossil fuels and land-use change are recognized as the principal sources of the elevated GHG levels; thus, policy makers are seeking ways not only to reduce GHG emissions, but to mitigate them through processes such as carbon sequestration. Considerable resources are being invested into the study of climate change and GHG mitigation, with research spanning local and global scales. In the Great Plains Region of the United States, agro-ecosystems have been identified as an important component of the regional GHG budget [...]
