Understanding utility disincentives to water conservation as a means of adapting to climate change pressures
A management model that systematically provides incentives for consumption more so than conservation may no longer promise the greatest social benefits. Read the full article at Journal of American Water Works Association.

Combined impacts of current and future dust deposition and regional warming on Colorado River Basin snow dynamics and hydrology
The Colorado River provides water to 40 million people in seven western states and two countries and to 5.5 million irrigated acres. The river has long been overallocated. Climate models project runoff losses of 5–20% from the basin by mid-21st century due to human-induced climate change. Recent work has shown that decreased snow albedo from anthropogenic dust loading to the CO mountains shortens the duration of snow cover by several weeks relative to conditions prior to western expansion of the US in the mid-1800s, and advances peak runoff at Lees Ferry, Arizona, by an average of 3 weeks.

WWA and CWCB release Climate Change in Colorado report
WWA and the Colorado Water Conservation Board (CWCB) today released the report “Climate Change in Colorado: A Synthesis to Support Water Resources Management and Adaptation,” which updates and expands on the 2008 WWA-CWCB report of the same name. The report, authored by WWA team members Jeff Lukas, Joe Barsugli, Imtiaz Rangwala, and Klaus Wolter, and WWA affiliate Nolan Doesken of the CSU Colorado Climate Center, presents findings on observed climate trends in the state, linkages with global changes, and projections of future climate and hydrology, as well as guidance on incorporating climate change into planning. Download the report here.

National Climate Assessment report describes impacts of climate change in U.S.
On May 6, the Third National Climate Assessment (NCA), Climate Change Impacts in the United States, was released by the U.S. Global Change Research Program. The comprehensive 829-page report assesses the science of climate change, and the impacts of climate change occurring now and through the 21st century, with the goal of better informing public and private decision-making at all levels. WWA’s Kristen Averyt was a lead author of the “Energy, Water, and Land Use” chapter. Kristen and several other WWA team members also contributed to regional and sectoral reports used as technical input for the NCA report. Explore the findings and download the NCA report here.
