Date: Posted 6/7/2002 100,000-Year Climate Pattern Linked To Sun's Magnetic Cycles HANOVER, N.H. – Thanks to new calculations by a Dartmouth geochemist, scientists are now looking at the earth's climate history in a new light. Mukul Sharma, Assistant Professor of Earth Sciences at Dartmouth, examined existing sets of geophysical data and noticed something remarkable: the sun's magnetic activity is varying in 100,000-year cycles, a much longer time span than previously thought, and this solar activity, in turn, may likely cause the 100,000-year climate cycles on earth. This research helps scientists understand past climate trends and prepare for future ones. Published...

After the sun sets on a summer evening and the sky fades to black, you may be lucky enough to see thin, wavy clouds illuminating the night, such as these seen over Billund, Denmark, on July 15, 2010. Clouds bright enough to see at night are not as hard to find as they once were. These so-called night-shining clouds are still rare — rare enough that Matthew DeLand, who has been studying them for 11 years, has seen them only once. But his odds are increasing. [Related: In Images: Reading the Clouds.] These mysterious clouds form between 50 and...

Credit: NASA/TRACE Researchers have discovered that one of the mysterious forces that sweep the sun's surface shows an unexpectedly strong connection with the number of sunspots, magnetic disturbances that can affect Earth's weather and telecommunications. The findings should improve predictions of the sun's dynamics and might even help scientists develop better climate models. Along with heat and light, the sun emits x-rays and magnetically charged particles that can endanger astronauts, fry circuits aboard satellites orbiting Earth, and overload electric power...

New sunspot 1035 is growing rapidly and it is now seven times wider than Earth. This makes it an easy target for backyard solar telescopes. ... The magnetic polarity of the spot identifies it as a member of Solar Cycle 24--the cycle we've been waiting for to end the deepest solar minimum in nearly a century. One spot isn't enough to end the lull, but sunspot 1035 could herald bigger things to come.

Climate Change: A team of international scientists has finally figured out why sunspots have a dramatic effect on the weather. It shows the folly of fearing the SUV while dismissing that thermonuclear furnace in the sky.Mankind once worshiped the sun. Now the world studiously ignores it as nations prepare to hammer out a successor to the failed Kyoto Protocol, which expires in 2012, in Copenhagen in December. Something is indeed rotten in Denmark. Our own government is committed to fighting climate change whether it be though Son of Kyoto or our own growth-capping, job-killing cap-and-trade legislation known as Waxman-Markey. Despite...

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...

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... But this dry statistic has more significance for the earth and its climate than all of Al Gore's gloom and doom about tailpipe emissions and rising sea levels. Whether the warm-mongers like it or not, the sun rules earth's climate — always has and always will.

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.

Unfortunately for Democrats, global warming is much more complicated science than what their theories predict. The greatest contributing factor to global temperatures isn’t atmospheric carbon dioxide, it’s the sun. The sun’s release of energy has natural variations and it is currently in a state known as solar minimum; the lowest energy output by the sun as it oscillates through an approximate 11 year cycle of activity, also known as the Schwabe cycle. This is the primary reason for the colder than normal temperatures recorded across the country this summer.

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. Yes, space has weather, in the form of solar radiation that varies with...

Climate Change: The Earth has been warming ever since the end of the Little Ice Age. But guess what: Researchers say mankind is to blame for that, too.s we've noted, 2008 has been a year of records for cold and snowfall and may indeed be the coldest year of the 21st century thus far. In the U.S., the National Oceanic and Atmospheric Administration registered 63 local snowfall records and 115 lowest-ever temperatures for the month of October. Global thermometers stopped rising after 1998, and have plummeted in the last two years by more than 0.5 degrees Celsius. The 2007-2008 temperature...

Climate Change: Channeling King Canute, G-8 leaders agree to wreck the world's economy, and ours, by pledging to prevent temperatures from rising more than 4 degrees by 2050. What if the Earth has other plans?Canute was the legendary king whose sycophantic followers praised his power and wisdom. He was The One of his time. He once stood on the shore and commanded the waves to halt. As the story goes, he was exercising his ego when in fact he was giving his followers a dose of reality — the power of man over nature is finite and inconsequential. We were...

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...

The sun's jet streams (in red, right) have reached their critical position, and soon the first sunspots of the new solar cycle may mar the star's currently placid-looking surface (inset).Credit: National Solar Observatory/GONG (main image); SOHO/MDI (inset) Maybe old Sol didn't hear the alarm clock. After a mysterious 2-year delay, the next 11-year solar cycle seems ready to begin, scientists say. That means the reemergence of sunspots, and with them periodic electromagnetic assaults on global navigation, communications, and power supplies--as well as brilliant auroras in the polar regions. For unknown reasons, the sun goes through cycles...

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...

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...

G‑d made the two great lights: the greater light to rule the day, and the lesser light to rule the night . . . And it was evening and it was morning, a fourth day.—Genesis 1:16, 19 One who sees the sun at its turning point should say, "Blessed is He who reenacts the works of Creation." And when is this? Abaya said: every 28th year.—Talmud, Tractate Berachot 59b Every 28 years the sun returns to the same position, at the same time of the week, that it occupied at the time of its creation—at the beginning of the fourth...
