Dearth of sunspot activity

“Following the end of the Sun's most active period in over 11,000 years, the last 10 years have displayed a clear cooling trend as temperatures post-1998 leveled out and are now plummeting.
“The reason? Sunspot activity has dwindled. There have only been a handful of days in the past two months where any sunspot activity has been observed and over 400 spotless days have been recorded in the current solar cycle.
“The sun's surface has been fairly blank for the last couple of years, and that has some worried that it may be entering another Maunder minimum, the sun's 50-year abstinence from sunspots, which some scientists have linked to the Little Ice Age of the 17th century,” reports one science blog.
“Long-time man-made global warming advocates NASA assure us that significant sunspot activity will return in 2012, but a recent a paper on recent solar trends by William Livingston and Matthew Penn of the National Solar Observatory in Tucson, predicts that sunspots will all but vanish after 2015.
“Since the sun, and not carbon dioxide, is the principle driver of climate change, a dearth of sunspot activity would herald a repeat of the Maunder Minimum, the name given to the period roughly from 1645 to 1715, when sunspots became exceedingly rare and contributed to the onset of the Little Ice Age during which Europe and North America were hit by bitterly cold winters and the Thames river in London completely froze.
“The observatory notes that solar cycles 21 and 22, which were characterized by being short and intense in their activity, led to the natural global warming observed in the 80s and 90s.
“Based on the past Armagh measurements, this suggests that over the next two decades, global temperatures may fall by about 2 degrees C - that is, to a level lower than any we have seen in the last 100 years.
“Temperatures have already fallen by about 0.5 degrees C over the past 12 months and, if this is only the start of it, it would be a serious concern,” concludes David Watt.”
