[1] Sea level rise (SLR) is an inescapable consequence of increasing greenhouse gas concentrations, with potentially harmful effects on human populations in coastal and island regions. Observational evidence indicates that global sea level has risen in the 20th century, and climate models project an acceleration of this trend in the coming decades. Here we analyze rates of future SLR on regiona...

In addition to the new cirrus cloud scheme described in Sect. 2.2, a prognostic cloud droplet number concentration (nl) equation for liquid clouds is added in the version of CAM3 used in this study compared with the version used in Liu et al. (2007a). Together with the prognostic liquid water mass (ql), ice water mass (qi), and ice crystal number concentration (ni), the complete set of equation...

Tian et al., (2004a), Oleson et al., (2003), and Tian et al., (2004b) recently identified significant differences between the current land surface parameters of the Community Land Model (CLM) used with the Community Climate System Model (CCSM), and global land surface descriptions from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite mapping. Specifically these investigations ide...

Wildfire risks for California under four climatic change scenarios were statistically modeled as functions of climate, hydrology, and topography. Wildfire risks for the GFDL and PCM global climate models and the A2 and B1 emissions scenarios were compared for 2005–2034, 2035–2064, and 2070–2099 against a modeled 1961–1990 reference period in California and neighboring states. Outcomes for the G...

Recent global climate model simulations for the IPCC Fourth Assessment report show a realistic North Pacific storm track and Aleutian Low for the present-day climate conditions. Under climate change, the storm track and Aleutian Low move northward and intensify. These changes shift precipitation northward along the Pacific coast of North America. In particular, precipitation is intensified over...

Mountain waters, glaciers, hazards, and biodiversity are vulnerable to the impacts of global warming. Warming is projected to amplify over mountains by global climate models, yet meteorological records do not show a uniform acceleration of warming with elevation. Here we explore warming-elevation relationships using records from 2660 meteorological stations and determine that the vertical gradi...
