  1. Carbon and the Forest

  2. What is carbon?

  3. What has carbon? You!

  4. Carbon Cycle

  5. Elevated Atmospheric CO2 and Climate

  6. Carbon and Climate Change

  7. Atmospheric CO2 1 petagram = 2.2 trillion pounds

  8. How do we reduce elevated atmospheric CO2? Make this smaller Make this smaller Make this bigger Make this bigger

  9. How do our options for reducing atmospheric CO2 compare? • Biggest factor • “Easy” to control and track, especially for point sources • In some cases “large” economic cost, but in some cases large economic benefits • Subject to disturbance reversals • Harder to track • We already have the technology • Generally large “co-benefits” We don’t have much experience managing ocean biogeochemistry

  10. Solve the Six Bits Puzzle • Each group of six students will have a set of six cards. Distribute them so each person has one. • On one card is a question. • Use the information on every card to answer the question. • You can not show anyone your card!

  11. How do we reduce elevated atmospheric CO2? Make this smaller Make this bigger Avoided Emissions or Substitution Forest C Sequestration

  12. How can forests help?

  13. Graphing Carbon in the Forest

  14. Carbon Stored in Live Trees 1st harvest 2nd harvest 3rd harvest

  15. Carbon Stored in Dead Wood 1st harvest 2nd harvest 3rd harvest

  16. Carbon Stored in Short-lived Wood Products 1st harvest 2nd harvest 3rd harvest

  17. Carbon Stored in Long-lived Wood Products Wood from 1st harvest has decomposed 3rd harvest 2nd harvest 1st harvest

  18. Carbon Saved by Not Using Carbon-intensive Products 3rd harvest 2nd harvest 1st harvest

  19. Forest Pool 1st harvest 2nd harvest 3rd harvest Forest

  20. Forest + Dead Wood Pool 1st harvest 2nd harvest 3rd harvest Dead wood Forest

  21. Forest + Dead Wood + Short-lived Products Pools 1st harvest 2nd harvest 3rd harvest Short-lived products Dead wood Forest

  22. Forest + Dead Wood + Short-lived Products + Long-lived Products Pool Wood from 1st harvest has decomposed 2nd harvest 1st harvest 3rd harvest Long-lived products Short-lived products Dead wood Forest

  23. Forest + Dead Wood + Short-lived Products + Long-lived Products + Carbon Saved Pool Wood from 1st harvest has decomposed 3rd harvest 2nd harvest 1st harvest Carbon saved Long-lived products Short-lived products Dead wood Forest
