Sunspot cycles may hold key
to global warming, cooling

24 May 08 – “The 2008 winter was the coldest in 40 years for the upper Midwest, Plains states and most of Canada. … Mississippi barge traffic, delayed by three weeks, was the latest since the modern waterway opened in 1940.

“Eau Claire, where "old-fashioned winters" have been a thing of the past, recorded 43 days of below-zero temperatures, while folks down in Madison shoveled away at a 117-year record snowfall throughout the season, as did many in New England and Canada.

"Rare snowfalls struck Buenos Aires, Capetown, and Sidney during their mid-year winter, while China continually battled blizzards. Even Baghdad experienced measurable snowfall.

“Antarctic pack-ice far exceeded what Captain Cook saw on his 18th century voyage into the Southern Ocean. On the continent itself the miles-thick ice continues to accumulate despite peripheral melting along the Antarctic Peninsula and occasional calving of an ice block. At the opposite pole, flow-ice once again spans the entire Arctic Ocean, and by April it had extended into the Bering Strait, making up for the much heralded melt-back last summer.

“From January 2007 through the end of January 2008, the average global temperature fell by nearly a degree Fahrenheit, based on data obtained by the MET Office in Great Britain and other international temperature monitoring networks.

“What are we to make of this? (At the) recent climate conference held in New York City, sponsored by the Heartland Institute … Solar experts highlighted how sunspots, and associated magnetic storms on the Sun's surface, affect Earth's weather and climate. The previous (very strong) 11-year sunspot cycle, associated with the recent warmth, ended in 2007, after having peaked in 2002. The new cycle should have already begun, but hasn't yet.

“In the absence of sunspots, solar flares are minimal….And when sunspots are at a minimum, more clouds form and correspondingly more sunlight is reflected back into space. The enhanced reflectance (albedo) cools the Earth…

“Past cool periods, identified with the late stages of the "Little Ice Age" and with the Maunder and Dalton climate minima, closely correlate with low sunspot numbers (astronomers have kept close tabs on sunspots since Galileo's time). Some solar-physicists are now saying if the current cycle doesn't begin to produce spots soon, we can expect a cool-down like the 19th-Century Dalton minimum - or worse. Decades-long cooling in the past brought crop failures to Europe from repeated summer frosts and restricted growing seasons.

“With grain shortages already staring us in the face, we'd be advised to begin thinking about a global cool-down instead of a warming that may or may not continue.”

Balgord, a consultant and writer, heads Environmental and Resources Technology in Middleton.
