Change and Variability in the Sierra Nevada Cryosphere

Sign up Here

Date/time: September 25th, 2019, 2:00 PM-3:00 PM
Presenter: Benjamin Hatchett, Ph.D., Western Regional Climate Center, Reno, NV

The Sierra Nevada has experienced notable variability in weather and climate during the last decade with other significant changes occurring over the past century. Regional climate projections indicate further increases in precipitation variability and the intensity of winter storms. These precipitation changes will be superimposed with continued warming, leading to severe declines in snowpack. I will share insight from a variety of studies aiming to characterize individual historic extreme weather and climate events as well as longer-term changes. Recent trends in snow line elevations, the timing of achieving sufficient early season snowpack for recreation, the partitioning of cool season precipitation into rain and snow, and the types and origins of snow droughts will be explored. The value of long-term, high elevation observational networks and ongoing citizen science projects, namely the Community Snow Observations (http://communitysnowobs.org/) project, will be highlighted.

Fire in California

Sign up Here

Date/time: November 21st, 2019, 1:00 PM-2:00 PM
Presenter: Chris Anthony, Dividion Chief, CAL FIRE

Chris Anthony is a Division Chief with CAL FIRE. During the webinar, he will provide an overview of wildfire trends in California and discuss factors behind why these fires are becoming larger and more destructive. He will also address some of the current endeavors underway to address these issues and answer questions from the group. Over Chris’ career with CAL FIRE, he has worked in disciplines ranging from forest management, firefighter training and safety, law enforcement, fire investigation, administration, and fire suppression operations. In 2015 Chris was appointed as the Deputy Task Force Leader for the Governors Tree Mortality Task Force; helping to lead an effort of over 80 federal, state and local entities in response to the Governors Emergency Proclamation to address the massive tree die off in the Sierra Nevada.
