Does the Senate really need to confirm 1,200 executive branch jobs? By Brad Plumer By Brad Plumer July 16, 2013 Follow @bradplumer The Senate has been bickering all day over how to confirm President Obama's nominees for various executive-branch positions.
The climate calculated by the GCM is used as input at the edges of the RCM for factors such as temperature and wind. RCMs can then resolve the local impacts given small scale information about orography (land height) and land use, giving weather and climate information at resolutions as fine as 50 or 25km.
Modern climate change is dominated by human influences, which are now large enough to exceed the bounds of natural variability. The main source of global climate change is human-induced changes in atmospheric composition. These perturbations primarily result from emissions associated with energy use, but on local and regional scales, urbanization and land use changes are also important.
