Long-Term Aridity Changes in the Western United States
TLDR
Using gridded drought reconstructions that cover most of the western United States over the past 1200 years, it is shown that this drought pales in comparison to an earlier period of elevated aridity and epic drought in AD 900 to 1300, an interval broadly consistent with the Medieval Warm Period.Abstract:
The western United States is experiencing a severe multiyear drought that is unprecedented in some hydroclimatic records. Using gridded drought reconstructions that cover most of the western United States over the past 1200 years, we show that this drought pales in comparison to an earlier period of elevated aridity and epic drought in AD 900 to 1300, an interval broadly consistent with the Medieval Warm Period. If elevated aridity in the western United States is a natural response to climate warming, then any trend toward warmer temperatures in the future could lead to a serious long-term increase in aridity over western North America.read more

TL;DR: A hydraulically based theory considering carbon balance and insect resistance that allowed development and examination of hypotheses regarding survival and mortality was developed, and incorporating this hydraulic framework may be effective for modeling plant survival andortality under future climate conditions.

Drought under global warming: a review
TL;DR: Wiley et al. as mentioned in this paper reviewed recent literature on the last millennium, followed by an update on global aridity changes from 1950 to 2008, and presented future aridity is presented based on recent studies and their analysis of model simulations.

TL;DR: There is a broad consensus among climate models that this region will dry in the 21st century and that the transition to a more arid climate should already be under way, and the levels of aridity of the recent multiyear drought or the Dust Bowl and the 1950s droughts will become the new climatology of the American Southwest within a time frame of years to decades.

Pacific and Atlantic Ocean influences on multidecadal drought frequency in the United States
TL;DR: Should the current positive AMO (warm North Atlantic) conditions persist into the upcoming decade, it is suggested two possible drought scenarios that resemble the continental-scale patterns of the 1930s and 1950s drought.
