Recent NewsSierra NewsMeasuring Available Water Sierra Link: At the American Geophysical Union Meeting last week in San Francisco, researchers presented the results from the first trial of NASA’s Airborne Snow Observatory (ASO). ASO was initiated to carry out two tasks—to measure the amount of snow and to estimate the date when the water from that snow would be available. Using LiDAR to measure snow depth and density and a imaging spectrometer to measure the reflectivity of the surface, notifying the rate of sunlight absorption, scientists produced high-resolution maps that show how much snow is there and when it will be available. This new method could help in adapting to the lower amounts of snowpack in the sierra by helping managers manage water easier. Rim Fire recovery effort gets a $1 million boost. Sierra Link: The Sierra Nevada Conservancy, an organization dedicated to improving the environmental, economic and social wellbeing of the Sierra Nevada region, has allocated $1 million in grant funding to aid in the Rim Fire recovery effort. Recovery efforts will help restore and protect the watershed which will benefit the area in many ways. State NewsWildfire in California’s Big Sur region destroys 22 structures. Sierra Link: A wildfire rips through Big Sur region in California in December. The warmest November in over a century and the continued drought in California may lead to an increase in Wildfires throughout California in 2014. . The importance of controlling water Sierra Link: Considering the current drought and what has been a very dry winter so far in the Sierra, reducing our water use seems as prudent as ever. "Since we cannot control the weather, what we can control is how we use water now by making extra efforts to avoid waste. As individuals and families, we all can start to reduce water use. We can also collectively strive to make prudent investments, both individually and as a region, in water conservation and recycling, so if this dry winter worsens, we’ve done as much as possible to be prepared." National NewsPoop-eating Pikas More Resilient to Climate Change than Previously Believed, Study Suggests Sierra Link: Pika are thought to be one of the most sensitive species when it comes to the warming effects of climate change in the Sierra. Warmer temperatures at higher elevations are forcing populations to adapt. This adaptation suggests there is hope for the for the species to survive the estimated temperature rises in the Sierra to an extent. Interior’s Secretary Jewell Announces New Wildlife and Climate Studies at the Southwest Climate Science Center Sierra Link: The Interior’s Southwest Climate Science Center is awarding nearly $1.2 million to universities and other partners for research to guide managers of parks, refuges and other cultural and natural resources in planning how to help species and ecosystems adapt to climate change. This includes a project planned to "examine the changing effects of the North Pacific Jet on water resources and Sierra Nevada fires. The NPJ is a high-altitude narrow path of strong winds over the North Pacific Ocean, and a key determinant of snowpack variability in California. Changes in the NPJ trajectory are forecasted for the future as the climate changes, which could greatly influence California water resources, ecosystems and fire. The project will inform decision makers for proactive wildland fire management" |
