Western Wildfires & Climate Change • 0.5⁰C is the difference between a high fire year and a low fire year.(http://news.discovery.com/earth/climate-change-yellowstone-fires.html ) Over this period, wildfire frequency was high whenannual average temperature was high and snowmelt was early.

AN INTRODUCTION http://socan.info Co-Facilitators: Alan Journet alanjournet@gmail.com Kathy Conway kathleendconway@gmail.com MEETINGS: Last Tuesday of the month (February 25th) ‘Do The Math – The Movie’ 6:00 pm Medford Pubic Library, 205 S. Central Ave.
Mission & Goal Statement The mission of SOCAN is: • To recognize the urgency for bold action against climate change • To promote awareness and understanding about the causes and consequences of climate change • To develop solutions and motivate concerned citizens to take action Our Goal: Collaborating with individuals and organizations throughout the world, we seek a reduction in the global atmospheric carbon dioxide concentration to 350 parts per million. To achieve this, we encourage both personal and governmental actions that reduce carbon dioxide emissions from individual to global levels.
