This eruption may have come to nothing:
Huge Solar Flare’s Magnetic Storm May Disrupt Satellites, Power Grids: A massive solar flare that erupted from the sun late Tuesday (March 6) is unleashing one of the most powerful solar storms in more than five years, a solar tempest that may potentially interfere with satellites in orbit and power grids when it reaches Earth….
The sun’s activity ebbs and flows on an 11-year cycle. The sun is in the midst of Solar Cycle 24, and activity is expected to ramp up toward the solar maximum in 2013.
But just in case I’ll be unplugging my computer tonight. Whatever happens with this solar flare, the underlying risk remains:
1 in 8 Chance of Catastrophic Solar Megastorm by 2020: The Earth has a roughly 12 percent chance of experiencing an enormous megaflare erupting from the sun in the next decade. This event could potentially cause trillions of dollars’ worth of damage and take up to a decade to recover from.
Such an extreme event is considered to be relatively rare. The last gigantic solar storm, known as the Carrington Event, occurred more than 150 years ago and was the most powerful such event in recorded history.
That a rival to this event might have a greater than 10 percent chance of happening in the next 10 years was surprising to space physicist Pete Riley, senior scientist at Predictive Science in San Diego, California, who published the estimate in Space Weather on Feb. 23.
“Even if it’s off by a factor of two, that’s a much larger number than I thought,” he said.
Earth’s sun goes through an 11-year cycle of increased and decreased activity. During solar maximum, it’s dotted with many sunspots and enormous magnetic whirlwinds erupt from its surface. Occasionally, these flares burst outward from the sun, spewing a mass of charged particles out into space
There’s an interesting site here.
Quakes – California and South America: We’ve got a quake in South America – 6.1 in Argentina (which seems a bit odd) along with a 4.0 that the news is saying was in “San Francisco” but the map shows it in the East Bay (on that Hayward / Calaveras side I’ve been worrying for a year or three now… so the question now is: “One and done? Or Foreshock?”…) This one is on the Hayward that runs right through the heart of U.C. Berkeley.
On the subject of cosmic influences on earth, the reference frame has an interesting post from Nick Calder on the effects of cosmic rays:
Supernova remnants → cosmic rays → solar modulation of cosmic rays → variations in cluster and sulphuric acid production → variation in cloud condensation nuclei → variation in low cloud formation → variation in climate.
Essentially we appear to have experimental evidence supporitng the Svensmark hypothesis. Changes in the world’s temperature are not primarily driven by human induced emissions of CO2.
The human induced global warming hype is simply another example of vested interests expropriating our wealth for their gain. We are living in the time before the theft is fully recognized. We do not realize how poor we now are. The money spent on desalination plants, bats in and out of roofs, windmills, solar cell, insulation schemes and as a consequence of building codes is gone forever. The results of that expenditure is not generating a return. It was wasted, we are the poorer for it. All the money printing in the world can not bring the real value of that expenditure back. It can but deceive us as to our financial state, for a while. It can also help redirect our view of who is responsible for our impoverishment when that impoverishment is realized.
