Sorry, Ryan, the Natural Resource Defense Council led you the wrong way. John Murawski seems to have used them for his statement that Chris Hayes* questioned.
NRDC seems to have assumed that carbon dioxide is the only contributor to global warming, so whatever produces the most carbon dioxide must be the greatest source of global warming.
But the sun is global warming on Mars, and Mars doesn’t have any people burning coal. Other findings from ancient fossils have led even Princeton’s Michael Oppenheimer to admit at the very least, “the uncertainties are too great to draw any conclusions right now.”
UPDATE: Corrected the name of the RCC’er who posted. Max Borders at RCCC has also contributed.
