The new Ice Age: Climate change could slow as sun simmers down

Sunspots are expected to disappear for years, maybe decades, after 2020
A sharp decrease in global warming might result
The last time the sun went to sleep, there were frost fairs on the Thames and ice extended for miles into the North Sea.
Now scientists have unearthed evidence that the sun is poised to enter its first period of ‘hibernation’ since the Little Ice Age of the early 1700s.
If they are right – and it’s a big if – it means global warming caused by greenhouse gases could be less severe over the next few decades than predicted.Frozen over: An engraving of an ice fair on the Thames in 1683
The sun goes through a regular cycle of activity that peaks every 11 years.During its most frenzied periods, huge magnetic storms erupt from the sun while vast sunspots appear on its surface. But during the quiet part of the cycle – the solar minimum – eruptions and sunspots are rarer.

But three separate studies reported at an astronomy conference in America this week have found clues that the sun is not waking up on schedule.
Dr Frank Hill, of America’s National Solar Observatory, showed that a regular jet-stream current within the sun – which was due in 2008 and 2009 – has failed to start up again.
A giant magnetic loop (right) filled with glowing-hot gas blasts away from the sun in 2003, while two Jupiter-sized sunspots erupt. Within ten years the sun will be in an unusual and extended period of hibernation that could trigger a mini-Ice Age, scientists claim
Meanwhile, Dr Richard Altrock, of Sacramento Peak Observatory – who has been studying the sun’s ‘atmosphere’, the corona, for 40 years – found that a tell-tale march of magnetic activity towards the poles that heralds the start of the solar maximum has failed to materialise.
And Matthew Penn, also of the National Solar Observatory, has shown that the strength of the magnetic field inside sunspots has been much weaker than expected and is in steady decline.
If this continues, the sun will have lost its spots completely by 2022.
The last time the sun went quiet was during the ‘Maunder Minimum’ from 1645 to 1715, when Europe and America suffered a succession of bitterly cold winters called the Little Ice Age.
The sun has already been unusually quiet for about four years with few sunspots – higher magnetic areas that appear as dark spots. Scientists predict the solar cycle starting in 2020 will see sunspots disappear altogether for a period of decades
The Thames – which was wider and slower in those days – regularly froze over, while sea ice choked the coasts of England.
Mike Lockwood, professor of space environment physics at the University of Reading, said: ‘Our research shows there is an eight per cent chance that we will return to Maunder Minimum conditions over the next 40 years.
‘But, given the observed and predicted rise in greenhouse gases, we find it would do no more than slow global warming a little.’
However, Joanna Haigh, professor of atmospheric physics at Imperial College London, said: ‘In a future grand minimum, the sun might again cool the planet by up to one degree. Greenhouse gases, on the other hand, are expected to raise global temperatures by between 1.5C and 4.5C by 2100.
‘So even if the predictions are correct, global warming will outstrip the sun’s ability to cool.’Read more: http://www.dailymail.co.uk/sciencetech/article-2004535/The-new-Ice-Age-Climate-change-slow-sun-simmers-down.html#ixzz1PWr08U5S
I wonder how they will tax us when they admit it´s global cooling?????????????????????
- Donovan, Norfolk England, 17/6/2011 10:23The global warming scam was inpart introduced to make a few people very rich, while diverting funds from the world’s poor. Shame on the scum who perpetuate this myth.

a quote from chris huhne; (eco fanatic and government minister) when challenged that the sun had a far greater impact on the earths climate than anything humans did’ ‘don’t be ridiculous, the sun has nothing to do with climate;’ so speaks the voice of the informed campaigner.

Global cooling taxes cometh.

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.
