    1. Global Warming Solutions Dr. Eban Goodstein, Lewis & Clark College, Portland, Oregon

    2. The “Carbon Blanket”: Getting Thicker Every Year Pre-industrial: 280 PPM Today: 384 PPM 2050: ??

    3. Clear Impacts: 1º F degree warming

    4. Temperate glacier retreat is global

    5. Portland, Oregon

    6. Local Impacts: PR Coastal flooding Coral extinction Change in rain patterns Change in temperatures Effects on Coquí population Hurricane intensity Economy, Etc….

    7. Global Impacts • The BAD: (worse as it warms more) Water shortages from snowpack loss… Increased floods and droughts… Extinction of many species & ecosystems… Spread of pests & diseases… More heat related illnesses and deaths… More intense hurricanes and typhoons

    8. Global Impacts • The GOOD (<4° F)Longer growing seasons… fewer cold-related deaths…more good golf days? • The SCARY – impacts to economy, social impacts, conflicts, …

    9. Catastrophic Impacts • Ocean acidification: potential collapse of marine foodchains • Fire-driven deforestation of Amazon: accelerated warming • Methane release from tundra: accelerated warming • Continental Ice Sheet Collapse: sea level rise of 35-40 feet

    10. “How far can it go? The last time the world was three degrees warmer than today – which is what we expect later this century – sea levels were 25m higher. So that is what we can look forward to if we don't act soon… How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree. That will be warmer than it has been for half a million years, and many things could become unstoppable.…We don't have much time left.” Dr. James Hansen, Director, NASA Goddard Institute for Space Studies. – The Independent 2/ 17/2006

    11. Emission Reduction Profile to achieve 450 PPM

    12. The model for a clean energy revolution Source: Goodstein 2004

    13. The Greatest Generation will transform the global economy from 2025-2045.

    14. FOCUS www.focusthenation.org

    15. Focus Components • The 2% Solution: Interactive webcast • The National Teach-in: Colleges & Universities • Green Democracy: Non-partisan political roundtables • Choose Your Future: National solutions vote

    16. 75 Days: Change the Future 1. Plant flags– today! 2. Build a teach-in with at least 50 faculty and engage thousands of students. 3. K-12, Faith groups, civic organizations: “The 2% Solution”
