Water Resources Research is becoming a fully open access journal
AGU remains committed to open science and open data. As part of our mission, we are focused on making science available to the widest possible audience.
With the growing open access requirements placed by funders on researchers around the world, this transition to an open access model also makes compliance easier.
All articles in the journal will be open access as of 1 January 2024. New submissions received after 12 July 2023 will require payment of an open access article processing charge (APC) of US$3,000 or an approved waiver in order to be published. To ensure that lack of funding does not become a barrier to publishing, AGU offers various funding support for APCs, including full waivers. For more information, please visit the FAQ.

Aridification of Colorado River Basin's Snowpack Regions Has Driven Water Losses Despite Ameliorating Effects of Vegetation
- Water Resources Research
-  20 July 2023
Key Points
-
A 10.3% reduction in Colorado Basin's present-day natural flow exists due to anthropogenic warming despite vegetation response to CO2
-
Anthropogenic warming reduced Colorado Basin's natural flow by roughly the storage of Lake Mead during the ongoing megadrought (2000–2021)
-
Greater aridification in snowpack regions is causing water losses to occur roughly twice as fast compared to non-snowpack regions
Plain Language Summary
The Colorado River Basin provides a crucial source of water for an expansive water-limited region covering the southwestern US and its major cities. Several studies have demonstrated that this basin has experienced substantial reductions in water availability due to warming. Here, we quantify how reductions in water availability have varied from 1954 to 2021 across this basin due to human-driven warming that has occurred since 1880. As a part of this analysis, we include how the vegetation response to historical increases in CO2 has impacted water losses. We find that the basin has roughly 10% less water available under present-day conditions due to warming since the 1880s. The majority of water loss has occurred due to a heightened sensitivity to warming in the basin's regions associated with snowpack, compared to regions without snowpack. We also demonstrate that without this warming, the Colorado Basin would have had significantly larger amounts of water available, equal to the size of Lake Mead, over the duration of the 2000–2021 megadrought.
