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.

right... I also read and saw a science movie where the entire northern hemisphere was plunged into an ice age in a matter of a week....

Don't believe everything you read or hear or see

Where will you be the day after tomorrow?

It'll happen, you'll see! ITS GONNA GET COLD, AND BADLY ANIMATED WILD DOGS WILL APPEAR FROM NO WHERE AND TRY TO EAT YOU!!!

Then the mutants from the umbrella corp. pop up and we have to take them down. Banding the human race together and ending all wars to fight the zombies (in the snow)..

Bring on the cooling.. Invest in Potatoes.. They saved Europe during the little ice age..

The one thing I can tell you is, at one time Antarctica was a warm and nice place; Sahara Desert was like the FL everglades and N.America plains were once swamps.

P.S. This is good to hear, I hate the summer heat..

You're thinking of the movie I AM ONE. :)

During an ice age, glaciers can indeed cover a continent in a very short period of time. This has been confirmed by a considerable body of research.

Even today, a glacier such as Greenland's Jacobshvan is moving at up to 8 miles a year.

even a mini-ice age? Say 200 years. Is there enough time? Keeping in mind average temp drops but does not drop 30 to 40 degrees.

For a little ice age? No. We didn't see glaciers advance more than a few dozen miles during the last Maunder Minimum; I don't believe anyone is predicting even that much for this one.

Still, the next significant Ice Age is due at some point. No one can predict when it will occur, but its definitely coming eventually.
