"Hockeystick" Mann is very selective about the facts

What he says about the direct effects of variations in total solar output is perfectly true but he ignores indirect effects as pointed out by Svensmark. And Svensmark is supported not only by direct experimental evidence but also by history. That's a lot to ignore -- enough by itself to identify the hoaxer that Mann is -- JR

Pat Robertson Proves Global Warming is a Hoax: No SUVs On Mars!

There have been claims by those not-in-favor of man-made global warming arguments that recent warming trends on Mars prove that man has no stake in the whimsy of Earth’s climate. Penn State meteorologist Michael Mann calls that scapegoating (though suspiciously not answering the charge made against the argument!)

“The small measured changes in solar output and variations from one decade to the next are only on the order of a fraction of a percent, and if you do the calculations not even large enough to really provide a detectable signal in the surface temperature record,” Mann explained.

“Solar activity continues to be one of the last bastions of contrarians,” he added. “People who don’t accept the existence of anthropogenic climate change still try to point to solar activity.”

Flashback: Wheat Crops and Sunspots

IT is now more than 200 years since the great astronomer William Herschel observed a correlation between wheat prices and sunspots. When the latter were few in number, he noted, the climate turned colder and drier, crop yields fell and wheat prices rose.
