Warming and Earlier Spring Increase Western U.S. Forest Wildfire Activity
Western United States forest wildfire activity is widely thought to have increased in recent decades, yet neither the extent of recent changes nor the degree to which climate may be driving regionalExpand

Changes in the Onset of Spring in the Western United States
Abstract Fluctuations in spring climate in the western United States over the last 4–5 decades are described by examining changes in the blooming of plants and the timing of snowmelt–runoff pulses.Expand

Changes toward Earlier Streamflow Timing across Western North America
Abstract The highly variable timing of streamflow in snowmelt-dominated basins across western North America is an important consequence, and indicator, of climate fluctuations. Changes in the timingExpand

Latent and sensible heat flux anomalies over the northern oceans : driving the sea surface temperature
Abstract A part of the large-scale thermodynamic forcing of the upper ocean is examined by relating monthly anomalous latent and sensible heat flux to changes in sea surface temperature (SST)Expand

Climate change scenarios for the California region
To investigate possible future climate changes in California, a set of climate change model simulations was selected and evaluated. From the IPCC Fourth Assessment, simulations of twenty-firstExpand

Emissions pathways, climate change, and impacts on California.
The magnitude of future climate change depends substantially on the greenhouse gas emission pathways we choose. Here we explore the implications of the highest and lowest Intergovernmental Panel onExpand

Human-Induced Changes in the Hydrology of the Western United States
Observations have shown that the hydrological cycle of the western United States changed significantly over the last half of the 20th century. We present a regional, multivariable climate changeExpand

North–South Precipitation Patterns in Western North America on Interannual-to-Decadal Timescales
The overall amount of precipitation deposited along the West Coast and western cordillera of North America from 258 to 558N varies from year to year, and superimposed on this domain-averageExpand
