CCR Section Spotlight:

Melting of Greenland and Antarctica.

A concern for the future is that the ice sheets of Antarctica and Greenland may respond to climate change more rapidly than previously thought, with grave implications for the rise of sea level. More...

Staff Spotlight:

Gokhan Danabasoglu

Ocean general circulation models routinely used in long climate simulations cannot afford to explicitly resolve some climatologically important small scale processes. These subgrid-scale processes include mesoscale and sub-mesoscale eddies as well as gravity current overflows. More...

Sensitivity of a model projection of near-surface permafrost degradation to soil column depth and representation of soil organic matter
The sensitivity of a global land-surface model projection of near-surface permafrost degradation is assessed with respect to explicit accounting of the thermal and hydrologic properties of soil organic matter and to a deepening of the soil column from 3.5 to 50 or more m. [article] [abstract]

Forests and Climate Change: Forcings, Feedbacks, and the Climate Benefits of Forests
The world's forests influence climate through physical, chemical, and biological processes that affect planetary energetics, the hydrologic cycle, and atmospheric composition. These complex and nonlinear forest-atmosphere interactions can dampen or amplify anthropogenic climate change. [abstract] [full text]

Improvements to the Community Land Model and their impact on the hydrological cycle

The Community Land Model version 3 (CLM3) is the land component of the Community Climate System Model (CCSM). CLM3 has energy and water biases resulting from deficiencies in some of its canopy and soil parameterizations related to hydrological processes. Recent research by the community that utilizes CLM3 and the family of CCSM models has indicated several promising approaches to alleviating these biases. [article] [abstract]
