Algore got so many innocent and well-intentioned but scientifically-uneducated people upset with his fear-mongering silliness. It's a damn shame. Those with a familiarity with how science works, and who had no political agenda to drive, just stood back and watched bemusedly.
Finally, even the HuffPo gets it. Harold Ambler's Mr. Gore: Apology Accepted. (h/t, No Looking Backwards, whence the borrowed image.) One quote:
If not carbon dioxide, what does "drive" climate? I am glad you are wondering about that. In the short term, it is ocean cycles, principally the Pacific Decadal Oscillation, the "super cycle" of which cooling La Niñas and warming El Niños are parts. Having been in its warm phase, in which El Niños predominate, for the 30 years ending in late 2006, the Pacific Decadal Oscillation switched to its cool phase, in which La Niñas predominate.
Since that time, already, a number of interesting things have taken place. One La Niña lowered temperatures around the globe for about half of the year just ended, and another La Niña shows evidence of beginning in the equatorial Pacific waters. During the last twelve months, many interesting cold-weather events happened to occur: record snow in the European Alps, China, New Zealand, Australia, Brazil, the Pacific Northwest, Alaska, the Rockies, the upper Midwest, Las Vegas, Houston, and New Orleans. There was also, for the first time in at least 100 years, snow in Baghdad.
If Lefties want to take over the world's economy, they need to try Plan D.
