The professional green CAGW alarmists predicted that global warming would bring climate change to Sierra Mtns. in the form of decreased snowfall levels - empirical evidence proves prediction to be without merit

Read here. Another 'Big Green' climate change prediction. Another climate change prediction fail.
As the adjacent chart shows, the snowfall trend for the California Sierra region has not been impacted by human CO2 emissions or the modern global warming since the late 1800's.
"The analysis of snowfall data from as far back as 1878 found no long-term trend in how much snow falls in the state, especially in the critical western slope of the Sierra Nevada mountains...There isn’t a trend significantly different from zero for the whole period,...just the past 50 years and there is no trend over this recent stretch either."..."Monthly snowfall totals from over 500 stations in California, some of which date back to 1878, are examined. Most data were accessed through the NOAA archive...For those regions characterized by consistent monitoring and with the most robust statistical reproducibility, we find no statistically significant trends in their periods-of-record (up to 133 years) nor in the most recent 50 years. This result encompasses the main snowfall region of the western slope of the Sierra Nevada Mountains." [John R. Christy 2012: Journal of Hydrometeorology]
