Churchville, VA—California’s southern Sierra snowfall has not changed over the past century, according to John Christy, a native Californian and atmospheric researcher who’s now in charge of the global temperature-measuring satellites. Christy reconstructed snowfall records at Huntington Lake, CA, from 1916–2009. The station’s data since 1972 had been missing, but Christy found two nearby stations had very high correlations with Huntington Lake. That allowed him to assess southern Sierra snowfall over nearly the past century.
