Climate Change Could Slash Snowfall in Southern California Mountains
Climate change is likely to wipe a lot of the white from those postcard winter scenes of Los Angeles ringed by snow-capped mountains, according to new research.
A UCLA study released Friday projects a significant decline in snowfall on the ranges that provide a dramatic backdrop to urban Southern California.
Scientists at the UCLA Department of Atmospheric and Oceanic Sciences downscaled 30 global climate-change models to the regional level, factoring in local topography. Professor Alex Hall, a coauthor of the study, said the regional simulations allowed researchers to examine the impacts of rising temperatures at an exceptionally small scale.Researchers compared the results with snowfall from 1981-2000, when an average of more than 10 inches a month could fall during the winter at high elevations of the Tehachapi, San Emigdio, San Gabriel, San Bernardino and San Jacinto mountains. More than 40 inches a month can coat the peaks.
