Can we dismiss the effect of changes in land‐based water storage on sea‐level rise?
Thomas G. Huntington
2008, Hydrological Processes (22) 717-723
The rate of global mean sea-level rise (SLR) during the 20th century is estimated to be 1.7 mm yr−1 ±0.3 yr−1 (Church and White, 2006). SLR during the 20th century was a result of thermal expansion of the oceans and the release of water from terrestrial storage reservoirs (Bindoff et al., 2007)....
Principal hydrologic responses to climatic and geologic variability in the Sierra Nevada, California
David H. Peterson, Iris Stewart, Fred Murphy
2008, San Francisco Estuary and Watershed Science 1-21
Sierra Nevada snowpack is a critical water source for California’s growing population and agricultural industry. However, because mountain winters and springs are warming, on average, precipitation as snowfall relative to rain is decreasing, and snowmelt is earlier. The changes are stronger at mid-elevations than at higher elevations. The result is...
