Repeat photos and supplemental measurements show that this warming is causing the retreat of glaciers and contributing to the elevational advance of alpine treeline. Additionally, a local drying trend (−3.80 mm yr −1 p < 0.001) was observed during the period 1955–1995. Furthermore, the annual trend is a result of both summer- and wintertime warming (0.037 ☌ yr −1, p < 0.001 and 0.036 ☌ yr −1, p < 0.001, respectively). Results show that mean annual temperature in the last two decades of the 20th century has been increasing locally at a rate of 0.06 ☌ yr −1 ( p < 0.001).
