Coupled modeling of land hydrology–regional climate including human carbon emission and water exploitation

Coupled Climate System Modeling

Modeling Carbon-Climate Interactions

How fast greenhouse warming will proceed depends on a large part on how fast carbon dioxide is increasing in the atmosphere. The abundance and growth rate of atmospheric CO2 is determined not only by the rate of anthropogenic emissions but also by the rates of biogeochemical processes that sequester carbon in the land and ocean. The biogeochemical processes in turn responds to and alters climat...

Impacts of urbanization on summer climate in China: An assessment with coupled land-atmospheric modeling

China has experienced unprecedented urbanization since the 1980s, resulting in substantial climatic effects from local cities to broad regions. Using the Weather Research and Forecasting model dynamically coupled to an urban canopy model, we quantified the summertime climate effects of urban expansion in China's most rapidly urbanizing regions: Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (...

Modeling Anthropogenic Impacts on the Carbon Cycle and Climate: From Land Use to Mitigation Scenarios

The impact of land use on the global carbon cycle and climate is assessed. The Bern carbon cycle-climate model was used with land use maps from HYDE3.0 for 1700 to 2000 A.D. and from post-SRES scenarios for this century. Cropland and pasture expansion each cause about half of the simulated net carbon emissions of 188 Gt C over the industrial period and 1.1 Gt C yr−1 in the 1990s, implying a res...

Land Use, Climate, and Water Resources-Global Stages of Interaction.

Land use and climate change can accelerate the depletion of freshwater resources that support humans and ecosystem services on a global scale. Here, we briefly review studies from around the world, and highlight those in this special issue. We identify stages that characterize increasing interaction between land use and climate change. During the first stage, hydrologic modifications and the bu...
