NOAA’s Space Weather Prediction Center (SWPC) produced their monthly solar cycle progression update yesterday. The news is not encouraging. We’ve had a drop in solar activity again in December, The sunspot count is lower, but the really worrisome thing is the Ap geomagnetic index. The solar dynamo has now dropped to magnetic activity levels last seen in late 2009. Readers may recall this post from December 23rd: Solar Geomagnetic Ap Index Hits Zero which was a bit unusual this far into cycle 24.

Dr. Horst Borchert, the Director of the Department of Physics of the Johannes-Gutenberg Institute, Mainz, Germany, presented a paper, Using Satellite Measurements to study the Influence of Sun Activity on Terrestrial Weather at the Space Weather Workshop held in Boulder, Colorado earlier this year. Dr. Borchert finds from satellite measurements that global warming between about 1980 to 2008 was "not anthropogenic but caused by natural activities of the Sun’s surface." He relates changes of the solar magnetic field to cosmic rays and cloud formation (the cosmic ray theory of Svensmark et al) and to effects on the North Atlantic Oscillation, which affects weather phenomena around the globe.

Using Satellite Measurements to study the Influence of Sun Activity on Terrestrial Weather

Abstract: The time rows of Terrestrial Climate Components (TCC) since the Eighties have shown some strong Influences by Extraterrestrial Components with the beginning of the 22. Sunspot period. Therefore the increase of ground near temperature on earth and oceans (2 –3 m above ground), called Global Temperature, during the warming period between about 1980 and 2008 seems to be not anthropogenic but caused by natural activities of Sun’s surface.

Northern Lights Still Rare due to Ongoing Solar Minimum by Angela Wang

The Northern Lights are at their lowest period of activity for the last 100 years, according to a Finnish Meteorological Institute study released on Tuesday.

The colourful light display, also known as the Aurora Borealis, is caused by photons emitted when solar winds hit the Earth’s atmosphere, and usually appears in the night sky.

The Northern Lights tend to follow an 11-year “solar cycle”, with the last solar minimum in 2008. But scientists have observed that solar activity and hence the appearance of the phenomenon remain at a minimum.

Researcher Noora Partamies said the solar minimum seems to be continuing, according to AFP.

Editorial: The sun’s activity has a place in climate science

THE idea that changes in the sun’s activity can influence the climate is making a comeback, after years of scientific vilification, thanks to major advances in our understanding of the atmosphere.

The findings do not suggest - as climate sceptics frequently do - that we can blame the rise of global temperatures since the early 20th century on the sun. (ICECAP NOTE: no you can blame a goodly portion on the global data center manipulation and population more than quadrupling enhancing heat island contamination)."There are extravagant claims for the effects of the sun on global climate,” says Giles Harrison, an atmospheric physicist at the University of Reading, UK. “They are not supported.”

Where solar effects may play a role is in influencing regional weather patterns over the coming decades. Predictions on these scales of time and space are crucial for nations seeking to prepare for the future.

Over the famous 11-year solar cycle, the sun’s brightness varies by just 0.1 per cent. This was seen as too small a change to impinge on the global climate system, so solar effects have generally been left out of climate models. However, the latest research has changed this view, and the next report by the Intergovernmental Panel on Climate Change (IPCC), due in 2013, will include solar effects in its models.

A new website launched this week allows the wonders of the northern lights to be viewed from the comfort -- and relative warmth -- of your own home.

The AuroraMAX website operated by the Canadian Space Agency is streaming a live feed of the colorful auroras from northern Canada each night from now until May.

Auroras are ribbons of colorful light that can be seen sweeping across the northern skies on winter nights. They are created by charged particles from the sun colliding with gasses in the Earth's atmosphere.

"Armchair skywatchers everywhere can now discover the wonder of the northern lights live on their home computer screen," CSA President Steve MacLean said in a statement. "We hope that watching the dance of the northern lights will make you curious about the science of the sky and the relationship we have with our own star, the sun."

Say Goodbye to Sunspots? by Phil Berardelli
Wednesday, September 15th 2010, 7:50 AM EDT

Scientists studying sunspots for the past 2 decades have concluded that the magnetic field that triggers their formation has been steadily declining. If the current trend continues, by 2016 the sun's face may become spotless and remain that way for decades—a phenomenon that in the 17th century coincided with a prolonged period of cooling on Earth.

Sunspots appear when upwellings of the sun's magnetic field trap ionized plasma—or electrically charged, superheated gas—on the surface. Normally, the gas would release its heat and sink back below the surface, but the magnetic field inhibits this process. From Earth, the relatively cool surface gas looks like a dark blemish on the sun.

Astronomers have been observing and counting sunspots since Galileo began the practice in the early 17th century. From those studies, scientists have long known that the sun goes through an 11-year cycle, in which the number of sunspots spikes during a period called the solar maximum and drops—sometimes to zero—during a time of inactivity called the solar minimum.

The last solar minimum should have ended last year, but something peculiar has been happening. Although solar minimums normally last about 16 months, the current one has stretched over 26 months—the longest in a century. One reason, according to a paper submitted to the International Astronomical Union Symposium No. 273, an online colloquium, is that the magnetic field strength of sunspots appears to be waning.

The upper panel shows the variations in North Atlantic Ocean basin wide sea surface temperatures in a simulation that includes historical variations in total solar irradiance and volcanic aerosols (blue), and in a simulation that in addition to the natural external 'forcings' also include anthropogenic 'forcings' for the last 150 years (red). Up to year 1900, the blue curve is consistent with available temperature observations, whereas only the red curve matches the observed temperature evolution in the 20th century. The lower panel shows variations in the large-scale ocean circulation in the Atlantic (black) and dates of major volcanic eruptions. (Credit: Image courtesy of University of Bergen)

ScienceDaily (Sep. 13, 2010) — A study presented in Nature Geoscience suggests that changes in solar intensity and volcanic eruptions act as a metronome for temperature variations in the North Atlantic climate.

A research team from the Bjerknes Centre for Climate Research in Bergen, Norway, has studied the climate in the North Atlantic region over the past 600 years using the Bergen Climate Model and the observed temperature evolution. They point to changes in the solar intensity and explosive volcanic eruptions as important causes for climate variations in the North Atlantic during this period.

Sun's Fluctuations Caused Partial Collapse of Earth's Atmosphere
Friday, August 27th 2010, 5:23 PM EDT

As the sun's energy rises and falls, so goes the Earth's atmosphere, a new study suggests.

These fluctuations in the sun's energy explain a recent partial collapse of the Earth's upper atmosphere, which had previously puzzled scientists.

A sharp drop in the sun's ultraviolet radiation levels triggered the collapse, according to the new study, detailed in the Aug. 25 edition of the journal Geophysical Research Letters. The researchers also found that the sun's magnetic cycle, which produces differing numbers of sunspots over an approximately 11-year cycle, may vary more than previously thought.

"Our work demonstrates that the solar cycle not only varies on the typical 11-year time scale, but also can vary from one solar minimum to another," said study team member Stanley Solomon of the National Center for Atmospheric Research (NCAR) in Boulder, Colo. "All solar minima are not equal."

The findings may have implications for orbiting satellites, as well as for the International Space Station.

Solar Sun Spot Cycles Impact on Crop Yields, Energy Use and Weather Patterns by Joseph Dancy

Last month we listened to Donald Coxe's weekly presentation to institutional investors. Coxe is the Chairman and Chief Strategist of Harris Investment Management. He has been a bull on the commodity markets for some time now and has correctly pointed out numerous investment opportunities in the energy, metals, and grain markets.

We were surprised when he mentioned the historical nature of the solar cycle and its' potential impact on global weather patterns and the agricultural sector. Most of the time Coxe he restricts himself to ‘worldly' indicators of supply and demand. Apparently an article on the subject recently appeared in Investor's Business Daily.

Since the performance of so much of our portfolio is driven by the weather – especially companies in the energy and agricultural sectors – and since Coxe notes the current sunspot cycle may point to lower global temperatures, we decided to examine the issue. Other long term forecasters we follow have not raised the issue to date.
