  • 4. What do these maps mean?
    The air downwind of the Navajo Nation power generating stations as polluted as large western cities, including Phoenix, Salt Lake, Denver and Las Vegas.
  • 5. Health Impacts
    NO2 andhealth:
    asthma; respiratory irritation; airway inflammation; headaches; pulmonary emphysema (chronically reduced lung function); impairment of lung defenses; oedema of lungs; eye irritations; loss of appetite;corrosion of teeth, and increased emergency room visits.
    The most vulnerable groups are young children, asthmatics, as well as individuals with chronic bronchitis, emphysema or other chronic respiratory diseases.
  • 6. Health Impacts, continued
    Ozone and  health: 
    NO2 is a catalyst for ozone formation.

  • 9. Many Changes Signal A Warming World
    Rising atmospheric temperature
    And……
    • Atmospheric water vapor increasing
    • 10. Glaciers retreating
    • 11. Arctic sea ice extent decreasing
    • 12. Extreme temperatures increasing
    • 13. ………….
    Rising sea level
    Reduction in NH snow cover
    IPCC WG1 (2007)
  • 14. What’s in the pipeline and what could come
    Warming will increase if GHG increase. If GHG were kept fixed at current levels, a committed 0.6°C of further warming would be expected by 2100. More warming would accompany more emission.
    CO2 Eq
    3.4oC = 6.1oF
    850
    2.8oC = 5.0oF
    600
    1.8oC = 3.2oF
    0.6oC = 1.0oF
    400
  • 15. What does this mean for Black Mesa?
    Warmer Temperatures
    More Intense Rainfall
    More Droughts
    More Dust storms
    More extreme weather

    And
    15.67 billion tons of coal in Black Mesa  3.5 ppm increase in carbon dioxide in the atmosphere,
    Increase in the carbon dioxide since the Long Walk is
    ~100 ppm
