Warming and Earlier Spring Increase Western U.S. Forest Wildfire Activity

TL;DR: It is shown that large wildfire activity increased suddenly and markedly in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons.
Changes toward Earlier Streamflow Timing across Western North America
TL;DR: In this paper, changes in the timing of snowmelt-derived streamflow from 1948 to 2002 were investigated in a network of 302 western North America gauges by examining the center of mass for flow, spring pulse onset dates, and seasonal fractional flows through trend and principal component analyses.
Human-Induced Changes in the Hydrology of the Western United States

TL;DR: A regional, multivariable climate change detection and attribution study, using a high-resolution hydrologic model forced by global climate models, focusing on the changes that have already affected this primarily arid region with a large and growing population.
Trends in Snowfall versus Rainfall in the Western United States
TL;DR: In this paper, a regional trend toward smaller ratios of winter total snowfall water equivalent (SFE) to winter total precipitation (P) during the period 1949-2004 was documented, with the most significant reductions occurring where winter wet-day minimum temperatures averaged over the study period, were warmer than 5°C.

TL;DR: It is found that annual temperature increases nearly double from the lower B1 to the higher A1fi emissions scenario before 2100, and three of four simulations also show greater increases in summer temperatures as compared with winter.
