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 Organization’s summary:
Continued Warming could lead to abrupt changes

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
![Page 16: Stephen H. Linder, Ph.D. © Duncan P. Walker, iStockphoto.com, 2007](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55156881550346486b8b4bd0/html5/thumbnails/16.jpg)
A different kind of causality

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
