State of the Environment, 2015 - 2016June 30, 2016
by Diana Liverman and Jonathan Overpeck, Co-Directors, Institute of the Environment
This past year had its share of environmental challenges—from dashed hopes for abundant rain and snowfall in the Southwest to historic low levels in Lake Mead and record-breaking temperatures across the globe.
Closer to home, unprecedented drought continues in both California and the Colorado River Basin. Sixteen years of warmer-than-normal temperatures and near-average snowfall have led to big reductions in Colorado River flow and plunging levels in Lake Mead and Lake Powell, the nation’s two largest reservoirs. We now sit on the edge of the first-ever official Colorado River water shortage, an event that will disproportionately impact Arizona, six other states, and Mexico if it comes to pass.
June 2016 CLIMAS Southwest Climate PodcastJune 30, 2016
In the June 2016 episode of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido look back at May and June to discuss the relatively mild weather of May, the near-record heat in June, and the transition into the monsoon. In the second half of the podcast, they dive into the weeds on monsoon climatology and the variable spatial and temporal patterns that characterize the monsoon in the Southwest. They highlight what we might expect in the next 90 days, along with a discussion of the difficulty of creating regional monsoon season forecasts (given the high degree of spatial and temporal variability, and the randomness of weather).
New Information From Watching a Forest BreatheJune 30, 2016
Using highly sensitive isotope analysis, a UA-led research team has obtained detailed measurements of carbon exchange in a temperate forest.
From Tucson to Paris for Global Well-beingJune 28, 2016
Last winter, University of Arizona faculty, researchers, and students joined delegates from around the world at a high-stakes climate change conference in Paris. As countries worked to make meaningful reductions in worldwide carbon emissions, the UA delegation shared expertise, research, and hope.
