If you add to this the evidence Roger A. Pielke, Sr. offers in his rebuttal of RC propaganda, I think one can safely and sanely declare that the AGW proponents are working with a house of cards: it looks like a great integrated, well designed structure, a consensus — especially to the so - called environmentalists and to their media and political allies — but so many of its foundational data sets (ocean temps, net ice melt, etc) don't support their model; at the very least, they don't support the hysterical, «save the planet» nuttiness that is rampant today.
