 A reception and book signing will follow the presentation.

McKibben says that “350 is the most important number in the world” – the number that leading scientists say is the safe upper limit for carbon dioxide measured in “parts per million” in our atmosphere. “If we can make this number known across the planet, that mere fact will exert some real pressure on negotiators. We need people to understand that 350 marks either success or failure for these climate negotiations.” 

With carbon dioxide levels already exceeding 350 parts per million, Bill McKibben, the Paul Revere of our time, is traveling the world to awaken people to the dire threat of global warming. In this special appearance, he’ll explain how Sonoma County can join thousands of others to send its own unique message through a countywide day of climate actions on October 24. “Our hope is for a powerful and unified call to action- a call that is global, scientific, and specific.”
