Snowfall unchanged in Sierra Nevadas?

A recent study has concluded levels of snowfall in the Sierra Nevada mountains have remained steady for the last 130 years, contradicting current climate-change models.

The study’s author, Alabama state climatologist and climate-change skeptic John Christy, analyzed snow measurements from loggers, railroad officials, mining companies, hydroelectric utilities, water districts and government organizations dating back to 1878, according to SF Gate. Perhaps most striking, Christy’s analysis showed no dramatic decrease in snow levels in the past 50 years, the period in which greenhouse gases are widely supposed to have increased the rate of global warming.

Critics of the study point out that many of Christy’s sources were unreliable amateurs, but Christy maintains there is no noticeable trend in the data. “The dramatic claims about snow disappearing in the Sierra just are not verified,” he said. “California has huge year-to-year variations and that’s expected to continue.”
