GREENHOUSE GASES
Carbon dioxide and other greenhouse gasses from power plants, cars, and other sources can harm human health directly. Ground-level ozone, for example, can contribute to asthma and other lung diseases.
The six greenhouse gasses are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
Global warming has broader health effects on the population. It has been found that global warming could increase rates of heat stroke, infectious diseases, drownings due to higher water levels, more frequent and intense wildfires, and water-quality problems.
In both magnitude and probability, climate change is an enormous problem. The greenhouse gases that are responsible for it endanger public health and welfare within the meaning of the Clean Air Act as announced by some agencies such as the "Environmental Protection Agency" in Washington.
The EPA announcement was the result of a review ordered by the Supreme Court. The court ruled that the EPA has the authority to regulate carbon dioxide and other greenhouse gasses if the agency determines they endanger health and welfare.
