3 Global climate is warming Warming has accelerated in the last 25 years Sea levels are rising, glaciers are melting Extreme weather events are changing in intensity and frequency CO2 emitted by fossil fuel combustion is a principal cause The World Health Organizations summary: Continued Warming could lead to abrupt changes

8 Strategies for Mitigation Federal Action Local Action Personal Measures


10 Framing Green Transportation Conserve Energy Protect the Environment National Security Clean Energy Cap GHG Emissions Energy Efficiency

12 Elevated concentrations of 6 GHGs Endangerment of public health and welfare Observed & Projected Climate Change The Air Pollutant Exposure mechanism Adverse health effects US EPA and Greenhouse Gases

13 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

14 A different kind of Technical Support Document U.N. Intergovernmental Panel on Climate Change -- 4 Assessment Reports U.S. Climate Change Science Program Syntheses and Assessments National Research Council -- 5 Reports

15 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

16 A different kind of causality Mediation by scenarios of causal sequences No dose-response relationship Projected effects Prospective harm Anticipatory action

17 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
