The sun is in the pits of a century-class solar minimum, and sunspots have been puzzlingly scarce for more than two years. Now, for the first time, solar physicists might understand why.

Solar Activity to Have Lowest High in 90 Years? Inc. Comments from Leif Svalgaard

Image AttachmentThe article, by National Geographic, contains quotes from Leif Svalgaard concerning the current Solar Cycle (24).

After a perplexing quiet spell, the sun appears to be stirring—but astrophysicists remain divided about what our star is going to do next.

The sun was expected to hit a low in 2008 as part of its normal 11-year cycle of activity.

But it stayed quiet until very recently, confounding scientists and sparking speculation of a sun-triggered "little ice age."

Solar physicists have denied that potential, saying that today's greenhouse gases have much more influence on global temperatures than the sun

Little Ice Age II, The Sequel?

Image AttachmentThe lingering cool temperatures being experience by much of North America has weather forecasters wondering it we are entering a new Little Ice Age—a reference to the prolonged period of cold weather that afflicted the world for centuries and didn't end until just prior to the American Civil War. From historical records, scientists have found a strong correlation between low sunspot activity and a cooling climate. At the end of May, an international panel of experts led by NOAA and sponsored by NASA released a new prediction for the next solar cycle: Solar Cycle 24 will be one of the weakest in recent memory. Are we about to start a new Little Ice Age?

According to the report, Solar Cycle 24 will peak in May 2013 with a sunspot count well below average. “If our prediction is correct, Solar Cycle 24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78,” says panel chairman Doug Biesecker of the NOAA Space Weather Prediction Center. This does not mean that we won't feel the results of renewed solar storm activity here on Earth.

NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming

Report indicates solar cycle has been impacting Earth since the Industrial Revolution

Some researchers believe that the solar cycle influences global climate changes. They attribute recent warming trends to cyclic variation. Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.

Now, a new research report from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

The Interplanetary Magnetic Field, It comes from the Sun!

Image AttachmentThe Sun is a big magnet.

During solar minimum the Sun's magnetic field, like Earth's, resembles that of an iron bar magnet, with great closed loops near the equator and open field lines near the poles. Scientists call such a field a "dipole." The Sun's dipolar field is about as strong as a refrigerator magnet, or 50 gauss. Earth's magnetic field is 100 times weaker.

During the years around solar maximum (2000 and 2001 are good examples) spots pepper the face of the Sun. Sunspots are places where intense magnetic loops -- hundreds of times stronger than the ambient dipole field -- poke through the photosphere. Sunspot magnetic fields overwhelm the underlying dipole; as a result, the Sun's magnetic field near the surface of the star becomes tangled and complicated.

New Solar Cycle Prediction

May 29, 2009: An international panel of experts led by NOAA and sponsored by NASA has released a new prediction for the next solar cycle. Solar Cycle 24 will peak, they say, in May 2013 with a below-average number of sunspots.

"If our prediction is correct, Solar Cycle 24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78," says panel chairman Doug Biesecker of the NOAA Space Weather Prediction Center.

It is tempting to describe such a cycle as "weak" or "mild," but that could give the wrong impression.

The ‘Baby Grand’ has arrived

No we aren’t talking pianos, but Grand Solar Minimums. Today a new milestone was reached. As you can see below, we’ve been leading up to it for a few years.

(Update: based on comments, I’ve updated the graph above to show the 2004 solar max by sliding the view window to the left a bit compared to the previous graph. – Anthony)

A typical solar minimum lasts 485 days, based on an average of the last 10 solar minima. As of today we are at 638 spotless days in the current minimum. Also as of today, May 27th, 2009, there were no sunspots on 120 of this year’s (2009) 147 days to date (82%).

NOAA: Mild Solar Storm Season Predicted
Thursday, May 28th 2009, 3:38 AM EDT

Although its peak is still four years away, a new active period of Earth-threatening solar storms will be the weakest since 1928, predicts an international panel of experts led by NOAA’s Space Weather Prediction Center and funded by NASA. Despite the prediction, Earth is still vulnerable to a severe solar storm.

Solar storms are eruptions of energy and matter that escape from the sun and may head toward Earth, where even a weak storm can damage satellites and power grids, disrupting communications, the electric power supply and GPS. A single strong blast of “solar wind” can threaten national security, transportation, financial services and other essential functions. The panel predicts the upcoming Solar Cycle 24 will peak in May 2013 with 90 sunspots per day on average. If the prediction proves true, Solar Cycle 24 will be the weakest cycle since number 16, which peaked at 78 daily sunspots in 1928, and ninth weakest since the 1750s, when numbered cycles began.

Scientists proclaim climate change is natural

Press Release: Citizens Electoral Council

As the Rudd government geared up its push for a CO2 cap-and-trade emissions trading scheme (ETS), which would annihilate what’s left of Australia’s collapsing physical economy, a public symposium last Sunday heard evidence from several leading Australian scientists that climate change is a natural phenomenon.

The symposium, ignored by the lying mainstream media, was held at Monash University and convened by Emeritus Professor Lance Endersbee. Several scientists identified hard evidence that severe cooling is the biggest climate challenge that we face—and its cause is entirely natural.

Professor Lance Endersbee, former Pro-Vice Chancellor of Monash University, clearly pointed out that for thousands of years human civilisation has endured natural climate variation much greater than any climate change in the last century. When warm climate prevailed civilisation flourished such as in Ancient Greece, whereas cold climate led to crop failure and mass migration of people escaping the bitter cold, for example during the Dark Ages.

Solar cycle 24: solar flares & social collapse or ‘crushing cold temperatures and global famine'? - by Alfred Lambremont Webre

Image AttachmentThis article is one of a continuing series on the impacts of Solar Cycle 24 (2009-2020).

On May 19, 2009, record low temperatures were recorded in 28 states, more than half the states in the United States of America. Many of these record low temperatures are the lowest in 100 years, and some the lowest in 115 years., a web portal tracking global temperatures reports, “If there had been record warmth in 28 states, your would have seen ‘we're-causing-global-warming’ headlines plastered across the front page of almostevery newspaper in the country, and TV hosts would have gleefully announced the dire news. . . . But had you even heard about this?”

NOAA’s full report on these locations and record low temperatures is set out at the end of this article.

In an April 2, 2009 article, retired U.S. Navy physicist and engineer James A. Marusek writes: “The sun has gone very quiet as it transitions to Solar Cycle 24…. We are now at a crossroad. Two paths lie before us. Both are marked with a signpost that reads “Danger”! Down one path lies monstrous solar storms. Down the other path lies several decades of crushing cold temperatures and global famine.” “A quiet sun will cause temperatures globally to take a nose-dive. We will experience temperatures that we have not seen in over 200 years, during the time of the early pioneers.
