Status of the Matter 1. A Knowledge Gap - What is Understood (scientists) - What is Known (public/policymakers) 2. The Climate Crisis - Climate Inertia Pipeline Effect - Positive Feedbacks Predominate Danger:Tipping Point Different Planet 3. Good News in Bad News: Opportunity - Must Keep CO 2 & Pollution Low - + Health, Agriculture, Environment!

Outline of Solution 1. Coal only in Powerplants w Sequestration Phase-out old technology. Timetable TBD 2. Stretch Conventional Oil & Gas Via Incentives (Carbon tax) & Standards No Unconventional F.F. (Tar Shale, etc.) 3. Reduce non-CO 2 Climate Forcings Methane, Black Soot, Nitrous Oxide 4.Draw Down Atmospheric CO 2 Agricultural & Forestry Practices Biofuel-Powered Power-Plants
