Washington - Global warming may not be occurring primarily because of carbon dioxide emissions, according to a report suppressed by the Environmental Protection Agency.
Alan Carlin, who has worked for the EPA for more than 35 years and has a bachelor's degree in physics and a doctorate degree in economics from Massachusetts Institution of Technology, co-wrote a report for "Endangerment Analysis for Greenhouse Gas Emissions under the Clean Air Act." According to the report, there are some inconsistencies with the theory that humans have caused global warming because of increased carbon dioxide emissions.
"The problems become particularly evident when one examines the downtrend period from roughly 1940 through the early 1970s," Carlin stated in the report. "There does not appear to be any relationship between carbon dioxide levels and global temperatures."
This report was written before a controversial climate change bill, also known as cap and trade, was discussed in the U.S. House of Representatives. The bill was designed to limit the amount of carbon dioxide industries released into the air, and would be one of the largest tax increases in U.S. history. But Al McGartland, director of the EPA National Center for Environmental Economics, decided not to release the information publicly and censored the report from lawmakers before they cast their vote.
