Sudden Global Cooling Has Scientists Perplexed

The past year has seen extraordinary and unexpected global cooling--inconsistent with global warming models, but completely consistent with the Superstorm model of how new ice ages begin.
For Great Britain, Ireland and Scotland, 2007 was a year without a summer. China has had its coldest winter in a hundred years. North America's snow cover is the most extensive in 50 years. The Antarctic is experiencing its coldest summer on record. It snowed in Baghdad for the first time in memory, and most of the world has seen exceptional and record breaking cold, and, across the US midwest, the most violent winter tornadoes ever recorded.
While scientists caution that this may or may not represent a trend, it is strikingly similar to conditions that appeared during the Little Ice Age that lasted into the 1740s, when there were very few sunspots and solar radiation appeared to decline.
At present, even though a sunspot of the type that usually heralds the beginning of a new solar maximum was observed in February, the sun's face has remained totally absent of sunspots.
While measurement of solar output is in its infancy, it is believed that solar variability is a major factor in the cycle of ice ages separated by brief interglacials that earth has been experiencing for the past three million years.
During the Little Ice Age, greenhouse gas levels in earth's atmosphere were low, with the result that the cooling resulted in ferocious winters and short summers, but not the extreme weather that has characterized past collapses from interglacial conditions to a new ice age.
That may not be true this time. Time will tell...
