Political activist Michael "Patron Saint of Charlatans" Mann denies solar influence on weather: "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”
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.

Numerous recent studies provide further support for the correlation of wheat prices with solar cycles.
See google scholar: wheat price solar cycle
So, if I understand, Mann (who now claims that his hockey stick was not important) is trying yet another way to make the MWP and LIA regional and and also crush the temperature amplitudes.
"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,"
Really? And CO2 is? Thats right, a fraction of parts per million. Got it?
He conveniently forgets about positive feedbacks when it suits him.
200 years ago there were great men of science. As the science got greater, the men got smaller.
Dr. Mann, our Sun's output warms our Earth from +2Kelvin "background" interstellar value to over +400 Kelvin: a change of 1 degree Kelvin would then be 0.025 per cent - a small bit indeed, but which would account for most change noted since the early Nineteenth Century.
Not saying the Sun is the only influence, but you and others such as Dr. Hansen have previously claimed the Sun can not have any effect.
i have heard that the sun pours 126 trillion horsepower onto the planet every second . humanity is truly a miniscule effort.
