Improvements in a half degree atmosphere/land version of the CCSM
A decadal climate projection between 1980 and 2030 using a nominal 0.5° resolution in the atmosphere and land components has been performed using the Community Climate System Model, version 3.5. TheExpand

Improved sea ice shortwave radiation physics in CCSM4: The impact of melt ponds and aerosols on Arctic Sea ice
AbstractThe Community Climate System Model, version 4 has revisions across all components. For sea ice, the most notable improvements are the incorporation of a new shortwave radiative transferExpand

Climate Sensitivity of the Community Climate System Model, Version 4
Equilibrium climate sensitivity of the Community Climate System Model, version 4 (CCSM4) is 3.208C for 18 horizontal resolution in each component. This is about a half degree Celsius higher than inExpand

Predicting 21st‐century polar bear habitat distribution from global climate models
Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions onExpand

The Influence of Local Feedbacks and Northward Heat Transport on the Equilibrium Arctic Climate Response to Increased Greenhouse Gas Forcing
AbstractThis study uses coupled climate model experiments to identify the influence of atmospheric physics [Community Atmosphere Model, versions 4 and 5 (CAM4; CAM5)] and ocean model complexity (slabExpand

Greenhouse gas mitigation can reduce sea-ice loss and increase polar bear persistence
On the basis of projected losses of their essential sea-ice habitats, a United States Geological Survey research team concluded in 2007 that two-thirds of the world’s polar bears (Ursus maritimus)Expand

Impact of sea ice on the marine iron cycle and phytoplankton productivity
© 2014 Author(s). Iron is a key nutrient for phytoplankton growth in the surface ocean. At high latitudes, the iron cycle is closely related to the dynamics of sea ice. In recent decades, Arctic seaExpand

Centennial-scale climate change from decadally-paced explosive volcanism: a coupled sea ice-ocean mechanism
Northern Hemisphere summer cooling through the Holocene is largely driven by the steady decrease in summer insolation tied to the precession of the equinoxes. However, centennial-scale climateExpand
