TranscriptionSegment 96: Climate Change Air Date: December 14, 2004 Anchor Intro: A group called the Sierra Nevada Alliance is out with a troubling new report on how global warming and climate change could affect the Sierra snow pack. Scientists from the Desert Research Institute, the US Geological Survey and University of California all contributed to the report. Shelly Purdy takes a closer look in tonight's Lake Tahoe Report. ((Take PKG)) ((Track 1)) 65 percent of northern California's and nearly 100 percent of northwestern Nevada's water supply comes from the Sierra snow pack. The scientific data gathered in the Alliance's new report called "Troubled Waters of the Sierra" raises concerns about what could happen to that snow pack over the next century. ((sot @ 3:47 Joan Clayburgh, Sierra Nevada Alliance)) "All the scientists who are looking at climate change say we're going to see a 2 ½ to 10 degree rise in the temperature and what that means for snow is less snow. And why we care about that for water is snow is a great storage system. It comes down in the winter and stores that water and slowly melts over the spring and summer." ((track 2)) If wintertime temperatures rise, instead of snow…rain would fall. And it's impossible to capture and store all that rain. That's why the Sierra Nevada Alliance put out this report. It's a wake-up call of sorts to encourage better planning, conservation and preparation for the future. ((sot @ 5:48)) "We're concerned about planning. When we relicense a dam or look at future growth and putting new houses in and what are they looking at? Our concern is they look at the last 100 years and expect that to be the future, so they expect the water to keep working the way it has. The snow to keep coming down in the same way. And that's clearly not true." ((track 3)) Climate scientists estimate that in 50 years there will be 50-percent less snow pack in the Sierra. And in 100 years, our wintertime snow pack will be nearly 90-percent less than it is today. Numbers like that are certainly troubling, but it's not too late to take action. ((sot @ 6:49)) "The more efficient we are with water the less dependent we are on a lot of water. They make washers and dryers that use less water. If you put in low flow showerheads in your home. If you buy homes with landscaping that doesn't require as much water that you like and looks nice. All of that makes it easier for you to adapt to a future maybe where we're going to have less water." ((track 4)) With the Lake Tahoe Environmental Education Coalition, I'm Shelly Purdy for KOLO News Channel 8.
