Inside Earth More Complicated than Realized

Tipping-point might refer to "geomagnetic field reversal"

In the churning movement of Earth's liquid outer core are weakening the magnetic field in some regions of the planet's surface, a new study says.

The changes "may suggest the possibility of an upcoming reversal of the geomagnetic field," said study co-author Mioara Mandea, a scientist at:

Trying to avert 'global warming?'
Try cooling the inner core/outer core, shell of liquid iron. This layer is cooler but still very hot, perhaps 7,200 to 9,000 degrees Fahrenheit (4,000 to 5,000 degrees Celsius!)

INSIDE FACT: The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the planet's magnetic field.

Natural magnetic fields are revealed as chaotic, ever-changing geometries. Scientists from NASA's Space Sciences Laboratory, excitedly describe their discoveries...

"In 2003 scientists found pronounced changes in the magnetic field in the Australasian region. In 2004, however, the changes were focused on Southern Africa.

The changes "may suggest the possibility of an upcoming reversal of the geomagnetic field," said study co-author Mioara Mandea, a scientist at the German Research Centre for Geosciences in Potsdam.
Survival Suggestion:
Programs which impact advocacy rather than science, are not likely to address new findings, nor cool this little blue-ball... We will achieve more success in placing majority of "global-warming taxes" toward accelerating colonization.

It is in a 'Stepped-up' Int'l shared Science pool toward colonization, rather than impacting tiny bursts of separate and competitive Space explorations; that human Life has a chance to avoid extinction... If we wait until meteorite escalations (2011) This may greatly complicate...

New Climate Sensors for Earth Malfunction on Aqua Satellite
...instrument on a new billion-dollar satellite designed to resolve questions about the changing climate is malfunctioning, NASA officials said today. The satellite, called Aqua, is the centerpiece of NASA's Earth Observing System, a suite...

The Aqua mission is a part of the NASA-centered international Earth Observing System (EOS). Aqua was formerly named EOS PM, signifying its afternoon equatorial crossing time. A timeline of Aqua on-orbit progress through the initial 120 day check-out period can be found here.

Why Does Earth's Magnetic Field Flip?
The computer-generated magnetic field even reverses itself, allowing scientists to examine the process...More.
