Default Solar Activity Diminishes; Researchers Predict Another Ice Age
Another mini ice age might be around the corner.

Link

Article:
Global Cooling comes back in a big way

Dr. Kenneth Tapping is worried about the sun. Solar activity comes in regular cycles, but the latest one is refusing to start. Sunspots have all but vanished, and activity is suspiciously quiet. The last time this happened was 400 years ago -- and it signaled a solar event known as a "Maunder Minimum," along with the start of what we now call the "Little Ice Age."
Tapping, a solar researcher and project director for Canada's National Research Council, says it may be happening again. Overseeing a giant radio telescope he calls a "stethoscope for the sun," Tapping says, if the pattern doesn't change quickly, the earth is in for some very chilly weather.
During the Little Ice Age, global temperatures dropped sharply. New York Harbor froze hard enough to allow people to walk from Manhattan to Staten Island, and in Britain, people reported sighting eskimos paddling canoes off the coast. Glaciers in Norway grew up to 100 meters a year, destroying farms and villages.
But will it happen again?
In 2005, Russian astronomer Khabibullo Abdusamatov predicted the sun would soon peak, triggering a rapid decline in world temperatures. Only last month, the view was echoed by Dr. Oleg Sorokhtin, a fellow of the Russian Academy of Natural Sciences. who advised the world to "stock up on fur coats." Sorokhtin, who calls man's contribution to climate change "a drop in the bucket," predicts the solar minimum to occur by the year 2040, with icy weather lasting till 2100 or beyond.
Observational data seems to support the claims -- or doesn't contradict it, at least. According to data from Britain's Met Office, the earth has cooled very slightly since 1998. The Met Office says global warming "will pick up again shortly." Others aren't so sure.
Researcher Dr. Timothy Patterson, director of the Geoscience Center at Carleton University, shares the concern. Patterson is finding "excellent correlations" between solar fluctuations, a relationship that historically, he says doesn't exist between CO2 and past climate changes. According to Patterson. we shouldn't be surprised by a solar link. "The sun [is] the ultimate source of energy on this planet," he says.
Such research dates back to 1991, when the Danish Meteorological Institute released a study showing that world temperatures over the past several centuries correlated very closely with solar cycles. A 2004 study by the Max Planck Institute found a similar correlation, but concluded the timing was only coincidental, as the solar variance seemed too small to explain temperature changes.
However, researchers at DMI continued to work, eventually discovering what they believe to be the link. The key factor isn't changes in solar output, but rather changes in the sun's magnetosphere A stronger field shields the earth more from cosmic rays, which act as "seeds" for cloud formation. The result is less cloud cover, and a warming planet. When the field weakens, clouds increases, reflecting more light back to space, and the earth cools off.
Recently, lead researcher Henrik Svensmark was able to experimentally verify the link between cosmic rays and cloud formation, in a cloud chamber experiment called "SKY" at the Danish National Space Center. CERN plans a similar experiment this year.

Even NASA's Goddard Institute of Space Studies -- long the nation's most ardent champion of anthropogenic global warming -- is getting in on the act. Drew Shindell, a researcher at GISS,
says there are some "interesting relationships we don't fully understand" between solar activity and climate. It happened 400 years ago. So it could happen again?

Discuss?

I doubt this is linked. But here in Australia we have had our worst drought on record, Most of Sydney's fresh water supply diminished (and they started stealing it from our water supply where I live). Food prices sky rocketed because crops and food where unable to grow. Extreme heats and humidity. Yet in the last couple weeks we've had nothing but rain. Sydney's water damn filled up by quite a lot, we've has mass flooding. Food prices a set to drop because crops and food are now growing on farms. Even our backyard has started growing lots of nice green grass which we haven't seen in years.

Thats very interesting, so global warming might be offset and then some by solar cooling.

I do have to wonder which one would be worse, global warming or cooling? I'm guessing cooling, but I'm no expert on these matters.

If everyone buys an SUV we can defeat the global cooling!

Warming is worse, cooling would be totally out of our control and something we'd just have to put up with but it has happened before and the world didn't end. It probably won't even be as bad as last time because of the greenhouse gasses we've dumped into the atmosphere. But it's not something we should all cling to as our great last hope. The cooling sounds like it'll take place over a long period of time, there still time for us to royally screw this place up.

What.

I would much prefer global cooling. Australia needs it. Its way to hot here. Even with the rains going. Might only be 22C at the moment. But this humidity is making me sweat badly.

Oh, silly me. For some reason Luke Skywalker popped in my head when I read your post[rofl]. Man my mind is being weird lately.

Meh, from what I've seen, we're supposed to be in an ice age at the momement. So the warming of the Earth is actually much greater because it's offsetting this. I'm not 100% about this, but it was a pretty creditable book.

Fact is we are in the middle of an Ice age.
believe it or not

The definition of an Ice age is the fact that there is ice on the planet,
which for an instance wasn´t the case back when the dinosaurs roamed.

Link? I didn't know about this. I knew there was a major ice age like 10k years ago. I had no idea there was one 400 years ago though. But currently in the middle? link?

If this is true, and earth is getting colder, I'm getting the hell out of Minnesota.

Hardly believable when Australia got record temperatures in January and I can't remember humidity being this high in a long time. Perhaps its only for those in the northern hemisphere. Perhaps the southern hemisphere is closer to the sun the the northern. Can't we switch places.

I don´t know any links,
but i do know that all that defines an ice age, is the fact that there is ice present on the planet.

A length of time during which ice sheets are found on the continents. Thus, an ice age is occurring at the present day, as a part of the Pleistocene glaciation, which began about 2 million years ago. Within an ice age there may be interglacial periods of milder climate. Ice ages last for some tens of millions of years with intervals of about 150 million years between them. The term is used more loosely to identify the last time that ice sheets covered much of Europe and North America.

I dunno, I can't remember a Minnesota winter this cold since I was a kid... if it gets any colder, we'll switch! [thumbup]

... Ever gotten frostbite before?
