The ongoing discussion of "man-caused global warming" cannot be concluded without adequate facts.
Alan Carlin of the Environmental Protection Agency provided interesting insight to recent developments in this field in his paper entitled, "Comments on Draft Technical Support Document for Endangerment Analysis for Greenhouse Gas Emissions under the Clean Air Act," dated March. This is the document that the EPA was accused of suppressing.
If you Google the title of the paper, you will find the means to download the 100 pages of information, which should be reviewed before a "Cap and Trade" bill is brought to vote in the U.S. Senate.
