Those who are concerned about global warming will be happy to discover when they read the Washington Post that the federal government has limits on greenhouse gas emissions. The Post had a page two article that told readers how the world would be different if the Tea Party folks, as personified by the House Republicans, ran the country.
The second item in the Post's list of differences is:
"It would no longer have federal limits on greenhouse gases."
Yes, that would be a big difference if the country actually did have limits on greenhouse gas emissions. The bill cited in the article would prohibit the Environment Protection Agency from using its regulatory powers to restrict emissions of greenhouse gases. However, there is no current statute that actually limits greenhouse gases, so the Tea Party folks don't have very much that they could change in this area.
