No matter what conclusions one gravitates towards regarding climate change and potential solar impacts, the data is irrefutable: the sun is slowly becoming more active. The 10.7cm radio flux spiked in late September with its highest reading in 18 months; now, and this is very significant compared to the pattern since March 2008, it has spiked again, exceeding the late September number and reaching a Cycle 24 maximum of 76.9. This is still a very low value compared to the solar maximum flux numbers, which routinely exceed 200. However, it is an upward move from the “basement” numbers of the...

"We're experiencing the deepest solar minimum in nearly a century," says Dean Pesnell of the Goddard Space Flight Center, "so it is no surprise that cosmic rays are at record levels for the Space Age [i.e. past 50+ years or so -etl]." Galactic cosmic rays come from outside the solar system. They are subatomic particles--mainly protons but also some heavy nuclei--accelerated to almost light speed by distant supernova explosions. Cosmic rays cause "air showers" of secondary particles when they hit Earth's atmosphere; they pose a health hazard to astronauts; and a single cosmic ray can disable a satellite if it...

Better dig out that wool hat and earmuffs. At the UN's World Climate Change Conference in Geneva over two weeks ago one of the worlds top climate change scientists, predicted that we are facing 10-20 years of global cooling. The Scientist, named Mojib Latif said the cooling would be the result of changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO). Latif also said that the NAO may be partly the cause of warming during the past 30 years. Latif says that he is not a global warming skeptic, and...

The average person doesn't associate coolness with the sun. The sun releases energy through deep nuclear fusion reactions in its core and has surface temperatures as hot as 10,000 degrees Fahrenheit, according to NASA's Web site. Not cool at all. But the sun's recent activity, or lack thereof, may be linked to the pleasant summer temperatures the midwest has enjoyed this year, said Charlie Perry, a research hydrologist with the U.S. Geological Survey in Lawrence. The sun is at a low point of a deep solar minimum in which there are little to no sunspots on its surface.

SOLAR MINIMUM VS. GLOBAL WARMING: From 2002 to 2008, decreasing solar irradiance has countered much anthropogenic warming of Earth's surface. That's the conclusion of researchers Judith Lean (NRL) and David Rind (NASA/GISS), who have just published a new analysis of global temperatures in the Geophysical Research Letters. Lean and Rind considered four drivers of climate change: solar activity, volcanic eruptions, ENSO (El Nino), and the accumulation of greenhouse gases. The following plot shows how much each has contributed to the changing temperature of Earth's surface since 1980: Volcanic aerosols are a source of cooling; ENSO and greenhouse gases cause heating;...

A new sunspot is emerging about 15o north of the sun's equator: map. Pete Lawrence sends this picture from his backyard observatory in Selsey, UK: "It is small, but a welcome sight, especially after the current long run of no surface activity," he says. Indeed, if this active region consolidates into a true dark-cored sunspot, it will break a string of nearly 52 spotless days, one of the longest quiet spells of the current solar minimum. Readers with solar telescopes are encouraged to monitor developments.

A new study in the journal Science by a team of international of researchers led by the National Center for Atmospheric Research have found that the sunspot cycle has a big effect on the earth's weather. The puzzle has been how fluctuations in the sun's energy of about 0.1 percent over the course of the 11-year sunspot cycle could affect the weather? The press release describing the new study explains: The team first confirmed a theory that the slight increase in solar energy during the peak production of sunspots is absorbed by stratospheric ozone. The energy warms the air in...

This image of the sun shows no sunspots continuing to be the case The sun seems to be back to its slumbering ways as we head towards the fall 2009. During the spring and summer months, sunspot activity, one measure of the sun’s energy output (another is the 10.7cm radio flux), was quite active. In July, the strongest flare in two years erupted from a spot that was rotating across the face of the sun. July was the third month in a row with heightened activity; this suggested a trend which would at last fall in line with projections...

NASA’s David Hathaway has adjusted his expectations of Solar Cycle 24 downwards. He is quoted in the New York Times here Specifically, he said: ” Still, something like the Dalton Minimum — two solar cycles in the early 1800s that peaked at about an average of 50 sunspots — lies in the realm of the possible.” NASA has caught up with my prediction in early 2006 of a Dalton Minimum repeat, so for a brief, shining moment of three years, I have had a better track record in predicting solar activity than NASA.

Climate Change: NASA predicts the lowest sunspot activity since 1928. Is a major solar storm in the offing? While we worry about man-made warming, the sun may soon show us who's boss. It's the sort of news that makes one's eyes glaze over. "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," said Doug Biesecker of the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

A sluggish, jet stream-like flow deep inside the sun could be to blame for the delay in increased solar activity that has been stumping astronomers. (Read "Sun Oddly Quiet—Hints at Next 'Little Ice Age'?") The jet stream, which is actually a plasma current called a torsional oscillation, has been migrating more slowly than usual through the star's interior, according to a team led by Frank Hill of the National Solar Observatory in Tucson, Arizona. Every 11 years the sun generates new jet streams near its poles. These streams slowly shift from east to west toward the solar equator over...

          Solar awakening: Two sunspots shown / July 4, 2009 / Dave Tyler During the past four years, the sun has been in a prolonged quiet phase which has led some to claim this signals a period of global cooling. The number of “blank” sunspot days, a measure of overall solar energy output, has been more than 30% above the long-term average.The year 2008 saw the sun with its lowest number of sunspots for any year in a century. This only fueled the speculation of an impending global cooling scenario.In fact, slight cooling has been observed since the year 2001, but the...

Inside the sun: more than just a glowing ball The unusually long quiet period of the Sun’s present activity may be due to the motion of “sluggish” jet streams beneath the solar surface, according to scientists at the National Solar Observatory (NSO) in Arizona, US. The scientists’ observations, which show an east–west jet stream has taken a year longer to migrate south by 10° than in the previous solar cycle, also indicate that the sun is moving into its next cycle. “We need to continue these observations for many, many more years to fully understand what is going on,” said...

Washington, May 5 (ANI): Some scientists say the prolonged lull in solar activity hints towards the next “Little Ice Age”, which could occur in the near future. The sun is the least active it’s been in decades and the dimmest in a hundred years. The lull is causing some scientists to recall the Little Ice Age, an unusual cold spell in Europe and North America, which lasted from about 1300 to 1850. The coldest period of the Little Ice Age, between 1645 and 1715, has been linked to a deep dip in solar storms known as the Maunder Minimum. During...

The Sun normally undergoes an 11-year cycle of activity. At its peak, it has a tumultuous boiling atmosphere that spits out flares and planet-sized chunks of super-hot gas. This is followed by a calmer period. Last year, it was expected that it would have been hotting up after a quiet spell. But instead it hit a 50-year low in solar wind pressure, a 55-year low in radio emissions, and a 100-year low in sunspot activity. Evidence from tree trunks and ice cores suggest that the Sun is calming down after an unusually high point in its activity. Professor Mike Lockwood,...

Cliff's Weather Gems By Randy Mann Since early in 2008, sunspot numbers (storms on the sun) have greatly decreased. Some scientists are concerned that the recent decline in our sun's activity is unusual and could persist. Others say that our sun is expected to start seeing an increase in sunspots based on previous long-term cycles, but those numbers were earlier predicted to pick up by the fall of 2008, which didn't happen. In August of 2008, there were no sunspots. Since that time, there has only been a slight increase in solar activity. Within the last 30 days, there were...

But inevitably this provoked the question as to why quality control seemed to be so poor on one of the world's leading official sources of climate data that it had taken an outside observer to point out that something was wrong. This is by no means the first time that data on which the official case for global warming rests have had to be...
