Oregon experienced very low snowpack levels in 2014 and historically low snowpack levels in 2015; now a new study suggests that these occurrences may not be anomalous in the future and could become much more common if average temperatures warm just two degrees (Celsius),ENN reports.
The low snowpack levels were linked to warmer temperatures and not a lack of precipitation, the researchers say. Based on simulations of previous and predicted snowpack, the study suggests that by mid-century, years like 2015 may happen about once a decade, while snowpack levels similar to 2014 will take place every 4-5 years.
Results of the study, which was supported by the National Aeronautics and Space Administration (NASA) and the National Science Foundation, have just been published the journal The Cryosphere.
“It is a cautionary tale,” said lead author Eric Sproles, who conducted much of the research as a doctoral student at Oregon State University and has been working as a hydrologist in Chile. “California received a lot of attention for its drought, but the economic and environmental impacts from those two low-snowpack years were profound in the Pacific Northwest.”
