Snowpack Trends & Projections

In the Pacific Northwest, small increases in winter temperatures have already caused significant loss of snowpack. Warmer temperatures change snow fall in low elevation areas to rain fall and cause earlier snowmelt. Recorded data shows that snowpack has decreased by 25% in the past 40 to 70 years. Projections show that for each degree Celsius of temperature increase snowpack will decline by 20% without any indirect influences. Factoring in increased precipitation due to warming, the projections show a 16% decrease in snowpack.
