Presentation transcript:

Global Warming Status 1. Knowledge Gap Between - What is Understood (science) - What is Known (public/policymakers) 2. Planetary Emergency - Climate Inertia Warming in Pipeline - Tipping Points Could Lose Control 3. Good News & Bad News - Safe Level of CO 2 < 350 ppm - Multiple Benefits of Solution

Assessment of Target CO 2 Phenomenon Target CO 2 (ppm) 1. Arctic Sea Ice Ice Sheets/Sea Level Shifting Climatic Zones Alpine Water Supplies Avoid Ocean Acidification Initial Target CO 2 = 350* ppm *assumes CH 4, O 3, Black Soot decrease

The fraction of CO 2 remaining in the air, after emission by fossil fuel burning, declines rapidly at first, but 1/3 remains in the air after a century and 1/5 after a millennium (Atmos. Chem. Phys. 7, , 2007).

Coal phase-out by 2030 peak CO2 ~ ppm, depending on oil/gas Faster return below 350 ppm requires additional actions
