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.
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.
Health Impacts, continued Ozone and health: NO2 is a catalyst for ozone formation. Reduction in lungfunction, asthmatriggerandincreasedrespiratorysymptomsaswell as respiratoryrelatedemergencydepartment visits, hospital admissions, and premature deaths.

Human and Natural Drivers of Climate Change coal coal

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
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
