Heatwaves constitute a major threat to human health and ecosystems. Projected increases
in heatwave frequency and severity thus lead to the need for prediction to enhance …

Anthropogenic climate change is decreasing seasonal snowpacks globally, with potentially
catastrophic consequences on water resources, given the long-held reliance on snowpack …

Mediterranean climate regimes are particularly susceptible to rapid shifts between drought
and flood—of which, California's rapid transition from record multi-year dryness between …

California is currently in the midst of a record-setting drought. The drought began in 2012
and now includes the lowest calendar-year and 12-mo precipitation, the highest annual …

A suite of climate data sets and multiple representations of atmospheric moisture demand
are used to calculate many estimates of the self‐calibrated Palmer Drought Severity Index, a …

Abstract In most Mediterranean climate (MedClim) regions around the world, global climate
models (GCMs) consistently project drier futures. In California, however, projections of …

Daily precipitation in California has been projected to become less frequent even as
precipitation extremes intensify, leading to uncertainty in the overall response to climate …

In the Southwest and Central Plains of Western North America, climate change is expected
to increase drought severity in the coming decades. These regions nevertheless …

The causes of the California drought during November–April winters of 2011/12–2013/14
are analyzed using observations and ensemble simulations with seven atmosphere models …

Precipitation extremes will likely intensify under climate change. However, much uncertainty
surrounds intensification of high-magnitude events that are often inadequately resolved by …
