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!

Time (Ma) 5 Global deep-sea foraminifera 18 O isotope records from 40 sites. Temperatures apply to ice-free state, i.e., before Antarctic glaciation (~35 Mybp). Dashed blue bars are times of ephemeral ice or ice sheets smaller than at present. Solid bar indicates ice sheets of modern or greater size.
