Greenhouse gases - dangerous

Environmental Protection Agency issued a final ruling that greenhouse gases “endanger” health and human welfare. Declaring that Carbon Dioxide endangers human health allows President Barack Obama to gloat at the Climate summit in Copenhagen. He may brag of this executive power to impose emissions caps on industry in the United States. Under the "endangerment finding," the EPA asserts the power to regulate CO2 and other gases blamed for global warming.

The Obama administration dismissed concern over the climategate controversy surrounding leaked e-mails from the British climate research center. Yet to be answered is the possible economic impact of regulations that constrain emmissions.
