CORVALLIS, Ore. -- Oregon's snowpack cut down in half over the past 77 years, and scientists say global warming is to blame for the decrease.
According to a report released Tuesday by the Oregon State University, the warming trend is most apparent in the spring. Compared to 1958, temperatures during the months of January, March and April are now almost 4 degrees higher. The precipitation level, however, has maintained a steady trend.
The shrinking snowpack continues to be the most evident sign of global warming, according to Geosciences professor Julia Jones. The snowpack in the mountain areas is a crucial natural reservoir for rivers that sustain the salmon population, as well as farming and ranching.
