Last year the ball was set rolling by Roland Emmerich in his magnum opus “2012”, now NASA issued a public awareness about a probable Apocalypse which might have ticked the funny bones of Stanley Kubrick for a much coveted sequel of his “2001 : A space Odyssey”. Besides the light side of it, a board of NASA scientists are issuing a notice in public interest to warn us about a probable series of Solar Storms. These storms are reported to play a huge part in the extinction of the world. The scientists are also of the opinion that USA will be the worst hit nation in this crisis of the whole planet. This radiation also will destroy the communication system of USA.
The scientists are of opinion that during 2012-2015, coronal mass ejections and massive solar flares would wreck havoc with satellites and will also destroy high voltage power transformers all over the globe. The scientists at the National Oceanic and Atmospheric Administration said that such storms were an event of the past, as well. A solar storm of this pattern occurred long back in 1859, destroying all telegraph machines due to the lack of proper resistant technology. In 1921, another solar storm with lower intensity took place but without such damaging proportions.
Now! If you want to worry yourself to death over a cosmological issue, … every 16,000 years or so, [based on magnetic data contained in Hawaiian lava flows], the Earth’s magnetic field flips, changes polarity.
When that happens, everybody dies.
Because until the magnetosphere stabilizes again, there is NO magnetosphere to protect us from cosmic rays, charged particles from the Sun, etc.
And the flip is over due. Apparently.
Now, THAT is something worth worrying about.
Can’t do anything about it.
Except, just stay in the state of grace … or … kablooey!!!
That was not in the report- just the article, which as you can see, is not from a source noted for scientific accuracy. This storm cycle isn’t supposed to be of apocalyptic proportions- it’s expected to be weaker than those in the late 50’s which, as you may have noticed, failed to end the world.
Earth’s magnetic field reverses every few thousand years at low latitudes and every 10,000 years at high latitudes, a geologist funded by the National Science Foundation (NSF) has concluded.
The magnetic field has exhibited a frequent but dramatic variation at irregular times in the geologic past: it has completely changed direction. A compass needle, if one existed then, would have pointed not to the north geographic pole, but instead to the opposite direction. Such polarity reversals provide important clues to the nature of the processes that generate the magnetic field, said Clement.
Since the time of Albert Einstein, researchers have tried to nail down a firm time-frame during which reversals of Earth’s magnetic field occur. Indeed, Einstein once wrote that one of the most important unsolved problems in physics centered around Earth’s magnetic field. Our planet’s magnetic field varies with time, indicating it is not a static or fixed feature. Instead, some active process works to maintain the field. That process is most likely a kind of dynamic action in which the flowing and convecting liquid iron in Earth’s outer core generates the magnetic field, geologists believe.
Figuring out what happens as the field reverses polarity is difficult because reversals are rapid events, at least on geologic time scales.
“It is generally accepted that during a reversal, the geomagnetic field decreases to about 10 percent of its full polarity value,” said Clement. “After the field has weakened, the directions undergo a nearly 180 degree change, and then the field strengthens in the opposite polarity direction. A major uncertainty, however, has remained regarding how long this process takes. Although this is usually the first question people ask about reversals, scientists have been forced to answer with only a vague ’a few thousand years.’”
The reason for this uncertainty? Each published polarity transition reported a slightly different duration, from just under 1,000 years to 28,000 years.
Clement examined the database of existing polarity transition records of the past four reversals. The overall average duration, he found, is 7,000 years. But the variation is not random, he said. Instead it alters with latitude. The directional change takes half as long at low attitude sites as it does at mid- to high-latitude sites. “This dependence of duration on site latitude was surprising at first, but it’s exactly as would be predicted in geometric models of reversing fields,” Clement said.
All it pretty much says is this about the solar maximum and how it might affect satellites and power grids, it has nothing to do with an “apocalypse”:
From the 2006 article:
This week researchers announced that a storm is coming–the most intense solar maximum in fifty years. The prediction comes from a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). “The next sunspot cycle will be 30% to 50% stronger than the previous one,” she says. If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958.
Like most experts in the field, Hathaway has confidence in the conveyor belt model and agrees with Dikpati that the next solar maximum should be a doozy. But he disagrees with one point. Dikpati’s forecast puts Solar Max at 2012. Hathaway believes it will arrive sooner, in 2010 or 2011.
From the 2010 article:
The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity…
The National Academy of Sciences framed the problem two years ago in a landmark report entitled “Severe Space Weather Events—Societal and Economic Impacts.” It noted how people of the 21st-century rely on high-tech systems for the basics of daily life. Smart power grids, GPS navigation, air travel, financial services and emergency radio communications can all be knocked out by intense solar activity. A century-class solar storm, the Academy warned, could cause twenty times more economic damage than Hurricane Katrina.
