US EPA and Greenhouse Gases Elevated concentrations of 6 GHGs The Air Pollutant Observed & Projected Climate Change Adverse health effects Exposure mechanism Endangerment of public health and welfare
Key Elements for Endangerment Analysis (1) Amounts being emitted by human activity (2) Accumulation (3) Changes in energy balance (4) Observed temperature and climatic changes (5) Observed changes in other climate sensitive sectors (6) Observed changes due to human induced buildup (7) Future projected change under different scenarios (8) Projected Risks to health society and the environment
A different kind of Technical Support Document U. N. Intergovernmental Panel on Climate Change -- 4 Assessment Reports U. S. Climate Change Science Program -- 21 Syntheses and Assessments National Research Council -- 5 Reports
A different kind of air pollution No direct respiratory or toxic effects No significant contribution required Not attributable to one source Global and regional Time scale of several decades
A different kind of causality Mediation by scenarios of causal sequences No dose-response relationship Projected effects Prospective harm Anticipatory action
Different kinds of health effects Changes in air quality -- strong and clear support Increases in temperatures -- support Changes in extreme weather events –- clear support Increases in vector-borne pathogens and aeroallergens -- not primary Susceptible populations
