There are variations in the 11 year cycle and other cycles of longer duration also seem to be at work here. Naturally, scientists have tried to predict the changing activity of the sun by examining the historical records and, more recently, using computer models. This is not to say that the predictions are always correct, no one correctly predicted the current ebb in solar activity. “In our professional careers, we've never seen anything quite like it,” said Dean Pesnell of the Goddard Space Flight Cente. “Solar minimum has lasted far beyond the date we predicted in 2007.”When will we stop worrying about global warming and prepare for the coming Little Ice Age II.
“It turns out that none of our models were totally correct," admited Pesnell, NASA's lead representative on the prediction panel. “The sun is behaving in an unexpected and very interesting way.” Though the face of the sun is not as blemish free as it was a few months ago, the latest images from SOHO show sunspot activity is picking up a bit. But the current level of activity is still quite low. In fact, the sun has gone more than two years without a significant solar flare. What does this portend for the weather here on planet Earth?
According to expert long-range forecaster Joe Bastardi, areas from the northern Plains into the Northeast will have a “year without a summer.” This is a reference to the year 1816, also known as the Poverty Year, during which severe and abnormally cold summer weather destroyed crops in Northern Europe, the American Northeast and eastern Canada. According to Bastardi the jet stream is displaced abnormally southward this spring, which is suppressing the number of thunderstorms that can form. The ones that do form in areas of the Ohio Valley and West are forming in places with very cold temperatures, which can lead to thunderstorms more electrically active than normal.
Despite claims by global warming activists that rising temperatures are extending growing seasons around the world, the opposite seems to be happening this year. Cool weather has pushed growth of Western Canada's wheat and barley crop at least 10 days behind schedule, according to the Canadian Wheat Board. “You're pushing development into a period with better likelihood of getting a frost,” said Bruce Burnett, director of weather and market analysis for the Canadian Wheat Board. “It's not particularly what we need at this moment. It's just too cool.”
Proving that this isn't only a Northern Hemisphere phenomenon, Brazil may cut this year’s corn output forecast for a third consecutive time, as a frost in several states caused more crop damage. According to Silvio Porto, agriculture policy director, corn growers may harvest less than the 49.9 million metric tons forecast previously announced as frost struck Parana and Mato Grosso do Sul states in the past two weeks. “It’s a worrying situation as corn has already suffered with a severe drought,” Porto said. “Still, it’s too early to know the size of the damage.”
New record cold temperatures have been seen in a number of locations around the world, marking this as one of the coldest springs in years. With reports of late season frost and snow falls, some are already forecasting a very cool summer. Not trying to sound alarmist or start any rumors but scientists' best conjecture regarding the conditions that signal the start of a new glacial period are cool, cloudy summers. Is this the beginning of Little Ice Age II, the sequel? If so, we will look back fondly on the time we were all so concerned about global warming. Remember, in the words of SF author Orson Scott Card, “'global warming' is just another term for 'good weather.'”
