article imageLack of Sunspot Activity Equals Ice Age

By Gar Swaffar     Sep 2, 2008 in Environment
No observable sunspots in the month of August correlates to a paper by two astronomers refused in 2005 by the journal Science for being too controversial. And is a possible signal of an Ice Age on the way. Not global warming!
Three past events in the observed life of the planet earth have led to much colder climate extremes. They are the reduced sunspot activity periods , Maunder, Dalton, and Spörer Minimums.
They correspond respectively to the periods, 1645-1715, 1790-1830, and 1420-1570*.
As reported in Daily Tech, the paper and the authors William Livingston and Mathew Penn suggest by extrapolation, a total disappearance of sunspot activity in ten years, which would be 2015.
At the time the paper was submitted to Science, sunspot activity was extremely active and the pair of researchers were ridiculed by most of their peers.
Abstract: We have observed spectroscopic changes in temperature sensitive molecular lines, in the magnetic splitting of an Fe I line, and in the continuum brightness of over 1000 sunspot umbrae from 1990-2005. All three measurements show consistent trends in which the darkest parts of the sunspot umbra have become warmer (45K per year) and their magnetic field strengths have decreased (77 Gauss per year), independently of the normal 11-year sunspot cycle. A linear extrapolation of these trends suggests that few sunspots will be visible after 2015.

The link between sunspots and the reduction in the solar magnetosphere affects cloud formation here on Earth, which in turn modulates climate.
Physicist Henrik Svensmark was the first to suggest the theory, and he as published several papers on the subject. One noticeably intriguing experiment was his "SKY" experiment which was being performed to consider the effects of galactic cosmic rays on the production of cloud cover on the Earth.
From the "SKY" link
To investigate the role of cosmic rays in cloud formation low in the Earth’s atmosphere, the SKY experiment used the natural muons (heavy electrons) that can penetrate even to the basement of the Danish National Space Center in Copenhagen. The hypothesis, verified by the experiment, is that electrons released in the air by the passing muons promote the formation of molecular clusters that are building blocks for cloud condensation nuclei.
The opinions and experiments as noted above are still subject to interpretation, the one incontrovertible fact though is that the climate is far too complex at this point in time to be considered easily predictable.
That is the essence of my argument against the concept of the global warming proponents who are seemingly in possession of a second set of Tablets from The Mount on which the Goracle has pronounced the existence of, and the inevitability of global warming due to the excesses of mankind, while he (Al Gore) travels the world in his private jet.
At least when California Governor Jerry "Moonbeam" Brown was telling us to "lower your expectations" he did so while driving an old state owned Plymouth sedan, from his apartment in Sacramento to his office.
NOT from his 21,000 sqaure foot mansion.
*The Spörer Minimum is also considered by some to have run from 1450-1550.
