DESCRIPTION: Graphic representation of major sources of greenhouse gas emissions
ADDITIONAL TALKING POINTS: Most of the global warming we’re seeing today is caused by carbon pollution from fossil fuels.* Other important contributors include deforestation, transportation, agriculture (crops and livestock), and industrial processes.**

2. Climate change in Oregon
Water Resources
Forests
Agriculture
Coasts and Ocean

3. Water Resources
Mountain snowpack
River and stream levels

4. Advanced technology Semiconductors and electronics
OR’s largest industry: Employment ~ 85,000
Water use ~ 2-4 million gallons per day (a small city!)
Increased costs of hydroelectric power

5. Oregon Forests Store carbon Filter pollutants Stabilize soils
Recreation
Endangered species habitat

6. Sustainable timber
Bioenergy

7. Climate change risks to OR Forests
Increased incidence of forest fires

8. Risk factors from climate change: Higher temperature
Less rainfall (2015 drought)
Med. scenario – 4x more by 2080 (2 million acres/year)

9. Other impacts of climate change on forests
Mountain pine beetle
Human health risk from fires
Insect predator risk

10. Oregon Agriculture: $5B in 2008
Vulnerable: water shortages, extreme summer heat,
increased insect pests

11. Oregon wineries Narrow optimal climates for grape varieties
Higher costs from changed plantings

12. Oregon beer! Benefits from: Moderate climate Abundant rainfall
Oregon hops
Benefits from:
Moderate climate
Abundant rainfall
Fertile soil
