According to KQED, warming temperatures have pushed the snow line in the Sierra up by 1,200ft – 1,500ft in recent years. To come up with this data, researchers used a special snow-level sensing radar to monitor the rain-snow line over the course of 10 years.

After gathering that data, they cross-checked the results with temperature data from the mid-20th century to examine the changes in the snow line over the years.ย Some are skeptical of this study, as it was relatively short. Although, these results aren’t a shock with warmer ocean temperatures and more frequent atmospheric river events, which tend to produce rainfall at higher elevations.

โ€œWhat weโ€™re saying is not that all storms are getting warmer,โ€ stated Ben Hatchett, a researcher at the Desert Research Institute In Reno. โ€œbut in a statistical sense, weโ€™re having more warm storms than we are cool storms. and thatโ€™s concerning because the future is projected to have more of these strong, warm storms.โ€

This study revealed that each year, from 2008-2017, 3% more precipitation fell as rain than snow in comparison with the previous 5 years.ย This is especially concerning for the state of California as a whole, as the state depends on the sierra snowpack to hold about a third of its water supply.
