LLANDUDNO, Wales, July 11 (UPI) --" Solar scientists, armed with the best data yet regarding the activities of the sun, say the Earth is headed for a "mini ice age" in just 15 years -- something that hasn't happened for three centuries.

Professor Valentina Zharkova, of the University of Northumbria, presented the findings at the National Astronomy Meeting in Wales this week, Britain's Independent reported Saturday.

Researchers, saying they understand solar cycles better than ever, predict that the sun's normal activity will decrease by 60 percent around 2030 -- triggering the "mini ice age" that could last for a decade. The last time the Earth was hit by such a lull in solar activity happened 300 years ago, during the Maunder Minimum, which lasted from 1645 to 1715."

Winter is here

SOMETHING incredible happened late last night as the Antarctic Vortex unleashed its swirling fury on south-eastern Australia.

Thundersnow. Yes, thundersnow. It’s a very rare meteorological phenomenon, especially in Australia, where you mix all the elements of a tropical style thunderstorm with the bitter cold of a blizzard. It’s quite the climatic cocktail.

It was hard to capture a still from the video that illustrates the phenomenon well, but if you look closely, you can see fat snowflakes. And yes, that’s lightning in the background - the video was taken at 10.30pm Saturday night. Source: NewsComAu

But that’s exactly what was on the menu as an aperitif to the main storm front in the Blue Mountains west of Sydney last night, as thunderstorms roared through the mountains accompanied by heavy snowfalls in the mountains themselves and in nearby towns like Orange.

Blue Mountains local and weather enthusiast Lindsay Pearce, who runs the site blackheathweather.com, captured the phenomenon from his verandah. You can watch it in the video at the top of this story. Nice work, Lindsay.

“Typically for NSW, we experience most of our thunderstorms in summer,” explains Mick Logan, a forecaster at the Bureau of Meteorology. “But thunderstorms can happen any time of the year if atmospheric conditions are right.

“Last night we had a series of strong fronts coming through, with really cold air at the mid levels of the atmosphere that allowed the line of thunderstorms to form.”

Thundersnow is so rare in Australia, especially outside the alpine regions, that the Weather Bureau keeps no data on its occurrence. And the Bureau keeps data on pretty much everything.

“For the Blue Mountains, it doesn’t happen every year,” Mick Logan says with a scientist’s typical understatement.

Mr Logan says the intense cold which has now engulfed the southern states will stick around for several days.

“The system has stalled a little bit, but there is more cold air to come through and there will be bands of moisture coming through for a couple of to come on and off.

Meanwhile, snow closed the Mitchell Highway between Bathurst and Orange earlier this morning but it is now open again.

Who knows? They are talking about it happening due to the activity of the Sun. That's different from our putting CO2 emissions into the air. The two are apples and oranges.

Goodbye, kind world (George Monbiot) - In common with all those generations which have contemplated catastrophe, we appear to be incapable of understanding what confronts us.

Maybe it'll give us breathing room to clean up our act. Because after activity goes down it goes up again.

SAGAN: We are releasing vast quantities of carbon dioxide, increasing the greenhouse effect. It may not take much to destabilize the Earth's climate, to convert this heaven, our only home in the cosmos, into a kind of hell.

I never realized thundersnow was such a big deal. It's quite common in western New York - and I'm guessing western Ohio and Pennsylvania as well.

Any snow is pretty rare here unless you are in the high country. In any of the cities snow is an event, and it rarely settles, never in Sydney I dont think.

I live in the foothills on the edge of the city, so it's an occasional experience, but nothing at all like north america.

An occasional event? That's my kind of climate! Climate without snow is pretty boring ... on the other hand when you have months and months of it ...

How are you for thunderstorms and tornadoes?

Lots of thunderstorms, mostly in Summer. I didn't think we got tornadoes, but susposedly we do.... Not as strong as in the US, I always knew them as willy willies, or dust devils. You don't hear about them much.In the tropics, you get cyclones, like your hurricanes. they can be incredibly destructive.

There is a short snow season here Victoria, NSW and Tasmania enough to get a few weeks of skiing in on the Alps, but rarely anything at sea level.

edit. In northern Australia, they have two seasons, the Wet and the Dry. The Wet is over summer months and it buckets down, the Dry is winter. The temperature remains pretty constant.

Quick!!!
Everybody get out their gas-guzzlers and crank up the polution, or else we'll all freeze in 15 years.

Wait a minute. I thought Global Warming was due to cows farting instead of having any relation to extra emissions from Sol.

Sun’s Irregular Heartbeat driven by Double Dynamo

A new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 percent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645. Results were presented July 9, 2015, by Professor Valentina Zharkova at the National Astronomy Meeting in Llandudno.

It is 172 years since a scientist first spotted that the Sun’s activity varies over a cycle lasting around 10 to 12 years. But every cycle is a little different, and none of the models of causes to date have fully explained fluctuations. Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun. Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.

“We found magnetic wave components appearing in pairs, originating in two different layers in the Sun’s interior. They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97 percent,” said Zharkova.

Zharkova and her colleagues derived their model of the magnetic field observations from the Wilcox Solar Observatory in California using a statistical technique called principal component analysis. They examined three solar cycles-worth of magnetic field activity, covering the period from 1976-2008. In addition, they compared their predictions to average sunspot numbers, another strong marker of solar activity. All the predictions and observations were closely matched.

Looking ahead to the next solar cycles, the model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2022. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch, and this will cause a significant reduction in solar activity.

“In cycle 26, the two waves exactly mirror each other — peaking at the same time, but in opposite hemispheres of the Sun. Their interaction will be disruptive, or they will nearly cancel each other. We predict that this will lead to the properties of a ‘Maunder minimum,’” said Zharkova. “Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity. When they are out of phase, we have solar minimums. When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago.”
