California's snowpack is deeper than last year, but more is needed, officials say

La Times: First, the good news: Thanks to a series of frosty winter storms, California`s snowpack is now double what it was last year at this time, according to officials. Now the bad news: The amount of water actually contained in the fluffy white stuff is still well below average. Snow levels measured statewide on Tuesday showed that water content was 56% of the historical average for Dec. 1. One year earlier, the water content measured just 24% of average.

Water supply for 2 billion people at risk as snowpack declines across northern hemisphere
2015-11-18 07:06:11| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Snowfields once considered permanent are shrinking from the Rocky Mountains to the Himalayas. Nearly 100 drainage basins across the northern hemisphere that currently supply water to 2 billion people in the American West, southern Europe, the Mideast and central Asia are at considerable risk over the next century. Dwindling water supplies will not be a universal impact of declining snowpacks due to climate change, however. Scientists have observed declining snowpack accumulation across the...

Sierra Nevada snowpack at historic low
2015-10-07 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: On April 1, California Governor Jerry Brown stood in a Sierra Nevada meadow atop parched, brown grass at an elevation of 6,800 feet, where there would normally be five feet of snow at that time of year and announced the states first-ever mandatory water restrictions. The Golden State is still in the grip of a severe drought that began in 2012, and new research suggests it is one of the worst in centuries. The day Gov. Brown announced the statewide water restrictions, snowpack in the Sierra...

California Epic Drought Leads to Lowest Snowpack in 500 Years
2015-09-15 16:19:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: The snowpack for the state of California--a critical source of drinking water for the state--hit its lowest level in the last 500 years, according to a study published yesterday in Nature. When the snowpack was measured in April--historically the high point for the season`s snowpack--it was just 6 percent of average for the past century. California`s 2015 Sierra Nevada mountains snowpack was "the worst in the past 500 years" http://t.co/v0NzH7AXdQ pic.twitter.com/v61PIWq4IG -- NYT Science (@NYTScience)...

Sierra Nevada snowpack lowest in 500 years; new study says
2015-09-15 15:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Canada Journal: The Sierra Nevada snowpack that is a critical water source for California fell to a 500-year low last winter far worse than scientists had estimated and underlining the severity of the current drought, according to new research. For the study, published in the journal Nature Climate Change, researchers compared the snowpack on April 1 with estimates from the last 500 years derived from tree ring studies. Tree rings provide a window into the climate of centuries past, expanding during warm periods...
