Sensitivity Study Helps Salt Lake City Plan for the Future
A new study published in the journal Earth Interactions has found that rising temperatures challenge Salt Lake City’s water supply. The 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. The sensitivity study aimed to help the city, and others in the Intermountain West, plan for the future.

Observations from pole-to-pole show climate patterns such as La Niña and El Niño contributed to some climate events this year. Trends consistent with manmade climate change over the last 50 years are also continuing. These include warming temperatures, melting glaciers and saltier seas, which are related to rising atmospheric greenhouse gas concentrations.
