A "little ice age" in our future?

Previous DailyTech stories have detailed recent cooling experienced by the planet, and highlighted some of the scientists currently predicting extended global cooling.  Even the UN IPCC has stated that world temperatures may continue to decline, if only briefly.

Now, an expert in geophysics at the National Autonomous University of Mexico has added his voice to the fray. Victor Manuel Velasco Herrera, a researcher at UNAM's Institute of Geophysics, has predicted an imminent period of cooling intense enough to be called a small ice age.

Speaking to a crowd at a conference at the Center for Applied Sciences and Technological Development, Herrera says the sun can both cool and warm the planet. Variations in solar activity, he says, are causing changes in the Earth's climate.

"So that in two years or so, there will be a small ice age that lasts from 60 to 80 years", he said. "The most immediate result will be drought."  Herrera says satellite temperature data indicates this cooling may have already begun.

Recent increases in glacier mass in the Andes, Patagonia, and Canada were given as further evidence of an upcoming cold spell.

Herrera also described the predictions of the Intergovernmental Panel on Climate Change (IPCC) as "erroneous". According to Herrera, their forecasts “are incorrect because are only based on mathematical models which do not include [factors such as] solar activity".

Herrera pointed to the so-called "Little Ice Age" which peaked in the 17th century, as a previous cooling event caused by solar fluctuations.

Herrera made his remarks at UNAM, located in Mexico City, is the oldest university on the North American continent.

This is not really a new prediction, its has been pretty much common knowledge since we started recording solar activity (sunspots) since the 1600's. Our last 'mini' ice age was called the Maunder Minimum and scientists noticed that during this time there were fewer spots on the sun then ever before, with some years having 1 or zero sunspots. Compare that to today where solar activity was once very high, and has now significantly dropped since 2004.

I am not saying this will come true, all I am saying is chances are, it will happen again. But for all we know next year the sun could suddenly become active again, its not exactly an exact science.
