SLCgreen, Dr. Mann & HEAL Utah Host Climate Event

On Wednesday, Dr. Michael Mann – one of the world’s most highly respected climate change scientists – gathered with SLCgreen program director Debbie Lyons, Salt Lake City water resources manager Laura Briefer, BYU geologist Barry Brickmore, University of Utah atmospheric scientist Court Strong and HEAL Utah policy director Matt Pacenza to call for immediate action to reduce greenhouse gas emissions.

Mann is the scholar behind the striking “hockey stick” graph demonstrating a sharp post-industrial increase in temperature.

The leaders highlighted a trio of definitive recent reports – from the Intergovernmental Panel on Climate Change, the National Academy of Sciences and the National Climate Assessment – demonstrating that climate change is already happening, and that in coming decades its effects will intensify.

The National Climate Assessment – released just last week – warns that Utah will face heightened drought, forest fires, protracted high temperatures, decreased stream flows and earlier snowmelt.

Rising Temperatures Challenge Salt Lake City’s Water Supply

Sensitivity study helps the City, others in the Intermountain West, plan for the future

In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the annual flow of streams that provide water to the city.

By midcentury, warming Western temperatures may mean that some of the creeks and streams that help slake Salt Lake City’s thirst will dry up several weeks earlier in the summer and fall, according to the new paper, published today in the journal Earth Interactions. The findings may help regional planners make choices about long-term investments, including water storage and even land-protection policies. Read more
