Internal variability in the climate system confounds assessment of human-induced climate
change and imposes irreducible limits on the accuracy of climate change projections …

Exceptional drought events, known as megadroughts, have occurred on every continent
outside Antarctica over the past~ 2,000 years, causing major ecological and societal …

Groundwater provides critical freshwater supply, particularly in dry regions where surface
water availability is limited. Climate change impacts on GWS (groundwater storage) could …

Snowpack stores cold-season precipitation to meet warm-season water demand. Climate
change threatens to disturb this balance by altering the fraction of precipitation falling as …

Drought is a complex and multivariate phenomenon influenced by diverse physical and
biological processes. Such complexity precludes simplistic explanations of cause and effect …

Efforts to understand the influence of historical global warming on individual extreme climate
events have increased over the past decade. However, despite substantial progress, events …

Mountain areas provide disproportionally high runoff in many parts of the world, but their
importance for water resources and food production has not been clarified from the …

Abstract In the western United States, the seasonal phase of snow storage bridges between
winter‐dominant precipitation and summer‐dominant water demand. The critical role of …

Despite the importance of precipitation phase to global hydroclimate simulations, many land
surface models use spatially uniform air temperature thresholds to partition rain and snow …

Documenting the rate, magnitude and causes of snow loss is essential to benchmark the
pace of climate change and to manage the differential water security risks of snowpack …
