In case you weren't already convinced of the awe-inspiring power of TPMDC, yesterday we corrected the many errors House Minority Leader John Boehner made during his Sunday appearance on This Week with George Stephanopoulos. We even provided the good congressman with a primer on cow flatulence and how it contributes to climate change. Last night, Ed Schultz provided a similar service. Watch:

For what it's worth, methane is about 20 times more potent a greenhouse gas than is carbon dioxide, but is only the second most important contributor to climate change. That's because it doesn't loiter about in the atmosphere or very long (in scientific jargon, it has a short half life in the atmosphere) and, for that reason and others, exists in the atmosphere at much lower concentrations than does carbon dioxide.
