The sun unleashed two powerful solar eruptions today (Jan. 28) in a spectacular double blast caught on camera by a NASA spacecraft.
The twin solar storms occurred in concert and marked an impressive start for the 2011 space weatherseason.
A video recorded by NASA’s Solar Dynamics Observatory shows the two sun storms erupting from opposite sides of the star. Neither of the events posed a space weather threat to Earth or its satellites, NASA officials said. Read more…
8 Strange Earth Changes That May Threaten Civilization
Say what, two suns may be visible from Earth in 2012? Everyday we seem to be getting bombarded with warning signs that our planet is changing rapidly. In fact, many of the changes are occurring for the first time in modern recorded history and all seem to indicate a need for civilization to adapt.
Record-breaking heat and cold are striking all corners of the globe; earthquake activity has spiked, even in places thought not to have active fault lines; birds, bees, fish, and other animals are dropping dead with no coherent cause, and there is a flurry of talk about galactic anomalies beginning to happen.
Since the man-made global warming theory has simmered down from a boil, many other concerns have surfaced that appear to minimize possible effects of CO2 concentrations as our greatest concern. Sure, many of these changes may be connected in some way, but the idea that there is a silver bullet to stop this train of collective events is unlikely.
One thing we can say is that we live in very interesting times. These unprecedented events are accelerating at a blistering pace, as we hurl through space on this ball we call Earth. It seems this turbulent cycle is going to continue to manifest despite our best human efforts to stop it. The only thing we can hope to do is digest the available information and plan for the worst, while hoping for the best. Assuredly, humans possess a far greater ability to adapt through technology than the animal kingdom, yet we certainly can’t thrive without protecting the entire biosphere.
Here are 8 strange Earth changes that should demand our attention: Read more…
POLE SHIFT PHENOMENA REPORTED by RUSSIAN SCIENTISTS
ALEXEY N. DMITRIEV
The Sun
Let’s begin with the Sun. The Sun is the center of our Solar System, and all life that is on this Earth came from the Sun. If there were no Sun, we would not be alive. This is simply scientific fact. And so any changes that occur in or on the Sun will eventually affect every person alive. The solar activity during this last sunspot cycle was greater than anything ever seen before. Yet every astronomer that I talked to about this except one insisted that everything was “normal.” That one person, who worked at NASA, claimed that what was going on within the Sun was absolutely incredible. She also said that she was not “allowed” to talk about it. But she talked anyway, because she felt that the world needed to know, but at the same time she asked that I not publicly discuss what she had said. Sort of a Catch-22. So the photo at left is just a hint (click on it for a larger view). It’s a recent picture of the Sun from, I believe, the year 2000, showing multiple sunspots ringing the sun on the two latitudes of 19.48 north and south. Some of you will see the significance of this much energy’s being emitted at this particular location.
So let’s look at the obvious question: Read more…
Earth May be Uninhabitable for Future Generations
Humans are in danger of making large parts of the Earth uninhabitable for thousands of years because of man made climate change, according to new evidence based on geological records.
The US study predicted that if society continues burning fossil fuels at the current rate, atmospheric levels of carbon dioxide could rise from the current level of 390 parts per million (ppm) to 1,000 by the end of this century.
The last time the world had such high levels of carbon dioxide temperatures were on average 29F(16C) above pre-industrial levels. Evidence has been found of crocodiles and palm trees at the Poles and only small mammals were able to survive.
Jeffrey Kiehl, of the National Center for Atmospheric Research (NCAR), who carried out the study, said the Earth could return to such temperatures over hundreds or even thousands of years.
But unlike last time, when it happened over millions of years, temperatures will rise too fast for species to adapt and change.
In the short term he said temperatures could rise by more than 10.8F (6C) by the end of the century, which will also wipe out species.
“This is happening at such a rate how will species, including humans, respond? The implications for the biosphere is of great concern.”
Dr Kiehl not only looked at geological records but also computer models to predict what will happen if carbon dioxide levels rise at such a rate.
He included ‘feed back factors’, such as melting sea ice, methane released from thawing permafrost and Amazon die-back.
This showed that temperatures will increase much faster than previously thought as a result of rising carbon dioxide.
“If we don’t start seriously working toward a reduction of carbon emissions, we are putting our planet on a trajectory that the human species has never experienced,” he said. “We will have committed human civilization to living in a different world for multiple generations.”
Dr Kiehl hit back at critics who claim that acting on climate change by reducing the use of fossil fuels will upset the world order.
“A truly conservative position is to conserve what we have, to not radically change things and if we do not want to radically change the environment then the conservative approach is to conserve the Earth as the human species has known it ever since we have been around on this planet.”
Earth Is Twice as Dusty as in 19th Century, Research Shows
ScienceDaily
If the house seems dustier than it used to be, it may not be a reflection on your housekeeping skills. The amount of dust in the Earth’s atmosphere has doubled over the last century, according to a new study; and the dramatic increase is influencing climate and ecology around the world.
Mahowald presented the research at the fall meeting of the American Geophysical Union in San Francisco Dec. 13.
Desert dust and climate influence each other directly and indirectly through a host of intertwined systems. Dust limits the amount of solar radiation that reaches the Earth, for example, a factor that could mask the warming effects of increasing atmospheric carbon dioxide. It also can influence clouds and precipitation, leading to droughts; which, in turn, leads to desertification and more dust.
Ocean chemistry is also intricately involved. Dust is a major source of iron, which is vital for plankton and other organisms that draw carbon out of the atmosphere.
To measure fluctuations in desert dust over the century, the researchers gathered existing data from ice cores, lake sediment and coral, each of which contain information about past concentrations of desert dust in the region. They then linked each sample with its likely source region and calculated the rate of dust deposition over time. Applying components of a computer modeling system known as the Community Climate System Model, the researchers reconstructed the influence of desert dust on temperature, precipitation, ocean iron deposition and terrestrial carbon uptake over time.
Among their results, the researchers found that regional changes in temperature and precipitation caused a global reduction in terrestrial carbon uptake of 6 parts per million (ppm) over the 20th century. The model also showed that dust deposited in oceans increased carbon uptake from the atmosphere by 6 percent, or 4 ppm, over the same time period.
While the majority of research related to aerosol impacts on climate is focused on anthropogenic aerosols (those directly emitted by humans through combustion), Mahowald said, the study highlights the important role of natural aerosols as well.
“Now we finally have some information on how the desert dust is fluctuating. This has a really big impact for the understanding of climate sensitivity,” she said.
It also underscores the importance of gathering more data and refining the estimates. “Some of what we’re doing with this study is highlighting the best available data. We really need to look at this more carefully. And we really need more paleodata records,” she said.
Meanwhile, the study is also notable for the variety of fields represented by its contributors, she said, which ranged from marine geochemistry to computational modeling. “It was a fun study to do because it was so interdisciplinary. We’re pushing people to look at climate impacts in a more integrative fashion.”
Magnetic Pole Shift May Close Airports
The recent changes at Tampa Bay International Airport regarding magnetic pole re-calibration and runway closure, chart alignment and runway number paint, could become a normal procedure for airports across the land. As an example nearby Peter O’Knight Airport is also scheduling similar changes at their facility.
It’s no surprise to many people that the Earth’s magnetic north pole has always wobbled over geological time, but what may be surprising is the speed at which the magnetic north pole has been recently moving and accelerating.
Although the magnetic north pole was first scientifically located in 1831, during 1904 it was discovered that the pole had begun moving to the northeast at about 9 miles a year (15 kilometers). Scientists in 1989 discovered that the pole shift speed was accelerating and had increased to 35 miles a year (56 kilometers), and was heading directly towards Read more…
Huge asteroid will hit Antarctica in 2012?
Update: Jan 13, 2011.
If you caught Starfire Tor on CoastToCoastAM last week you may have heard her mention that ‘they’, the PowersThatBe know that an incoming near earth object is going hit earth sometime in the next 2 years. There is evidence to suggest the object is going to strike one of the poles… most likely the south pole. Special Scientific teams have been down in Antarctica mapping the ice shelf for probable weak points. The object is rumored to be 800 meters wide and when it hits the south pole the entire ice shelf will collapse within months.
A University of British Columbia Professor published an online article that projected an 800m asteroid would hit Antarctica in the fall of 2012. His article was on the http://www.phas.ubc.ca website Read more…
Solar Wind to Reach Earth In Few Days, Spark Auroral Activity
A dark coronal hole at the Sun center was captured in extreme ultraviolet light by National Aeronautics and Space Administration’s (NASA) solar dynamics observatory on Jan. 10.

A dark coronoal hole at the Sun center was captured in extreme ultraviolet light by National Aeronautics and Space Administration’s (NASA) solar dynamics observatory. As the Sun continues to rotate, the high speed solar wind particles blowing from this hole will likely reach Earth in a few days and may spark some auroral activity.
Coronal holes are areas of the Sun’s surface that are the source of open magnetic field lines that head way out into space. They are also the source regions of the fast solar wind, which is characterized by a relatively steady speed of about 800 kilometers per second.
As the Sun continues to rotate, the high speed solar wind particles blowing from this hole will likely reach Earth in a few days and may spark some auroral activity, according to NASA.
Here, the solar dynamics observatory detected a giant solar filament that became unstable and erupted from the far side of the Sun. A filament is a large, bright feature extending outward from the Sun’s surface, often in a loop shape. Some filaments break apart and give rise to coronal mass ejections.
