Snowpack in California’s Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report. The research is the first to show how the 2015 snowpack compares with snowpack levels for the previous five centuries. California’s current record-setting drought began in 2012, the researchers note in their report.
