Don't expect to see pictures below much in the future. From the LA Times:
By mid-century, the amount of snow draping the mountains could decrease 30% to 40%, researchers say. If greenhouse gas emissions continue unabated, the ranges could lose two-thirds of their snow by century’s end.
That means fewer and fewer days in coming decades will reflect the classic images of sun and snow that have idealized life in Southern California since 1920s citrus-crate labels beckoned to Easterners.
“It kind of cuts to our identity,” said Jonathan Parfrey, a commissioner with the Los Angeles Department of Water and Power who is also executive director of Climate Resolve, a local nonprofit concerned with climate change.
This has been my experience, walking up to the snow in our local mountains (the Topa Topas) every winter. Even at 6000+ feet, it snows less frequently, and when it does snow, it snows less.
It's impossible to remove the natural variability, thank God, but still -- much less snow.
