WASHINGTON -- America smashed the record for billion-dollar weather disasters this year with a deadly dozen -- and counting. With an almost biblical onslaught of twisters, floods, snow, drought and wildfire, the U.S. in 2011 has seen more weather catastrophes that caused at least $1 billion in damage than it did in all of the 1980s, even after the dollar figures from back then are adjusted for inflation.
The National Oceanic and Atmospheric Administration added two disasters to the list Wednesday, bringing the total to 12. The two are the Texas, New Mexico and Arizona wildfires and the mid-June tornadoes and severe weather.
NOAA uses $1 billion as a benchmark for the worst weather disasters.

World Meteorological Organization Confirms Climate Change Accelerated In Past 10 Years; 2011 Was 11th Warmest On Record

Increasingly destructive tornadoes, floods and other indicators of global warming are also occuring with heightened frequency around the world. The new study found extreme weather events increased from 2001 to 2010 at an alarming rate consistent with global climate change. Worldwide, this included an increase in floods by 63%, drought 43%, heat waves 43%, heavy rain 43%, fires 25%, and tropical cyclones 24%.
Ok so then that suggests that the core has changed its axis, or is being pulled towards something, abit like one of them compass, spinning wheel thing they used to have in ships way back. The old lion is turning its head I heard somewhere.
Rapid changes 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.
"What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field," said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen.
The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said.
The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the planet's magnetic field.
The study, published recently in Nature Geoscience, modeled Earth's magnetic field using nine years of highly accurate satellite data.
Flip-Flop
Fluctuations in the magnetic field have occurred in several far-flung regions of Earth, the researchers found.
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.

Many have noticed the recent increase in extreme weather:
What kind of technology would be effected? Would it be life changing?

...the overwhelming majority of meteorologists and climatologists attribute it [the recent increase in extreme weather] to global warming, not geo-magnetic field changes.edit on 16-5-2012 by DJW001 because: (no reason given)
Thank you for taking the time to answer me... Just one more that I can think of..... Would all this happen suddenly or gradually? For example, since the poles have been wandering for some time already, but it's just speeding up now, does that mean some of the difficulties with these technologies that we have from time to time could be caused by the poles shifting? And maybe we could start seeing more? Or are you saying we'd only have those problems if a very large shift were to occur suddenly? Again, thank you.
What percentage of meteorologists and climatologists attribute the recent increase in extreme weather to global warming and not to geo-magnetic field changes?

Yeah but what effects would/will it have on our world? Any? Effects on people? I am woefully uneducated on this topic.
The geo-magnetic pole is constantly wandering. Its only real effect is on navigation; one must offset the compass readings on maps. It is believed that the geo-magnetic field weakens and reverses every 450,000 years or so. This might result in a bit of extra radiation from the solar wind, but it does not cause mass extinctions. If such a reversal were to happen now, it would be disruptive of our technology, but since much information is carried on fiber optic cables, it would not be too difficult to work around.

Outside of Helium, which is clearly agenda driven, the only source cited that connects the geo-magnetic field with weather and climate is Knudsen and Riisger's study, which supports Svensmark's cosmic ray theory. It suggests that as the magnetic field diminishes, increased cosmic rays would lead to increased precipitation. That is a completely different issue than routine wandering.

I can't think of a single one who doesn't. Can you?

Your answer is both zero... and greater than zero simultaneously.

100% is an overwhelming majority, don't you think?
I am aware of the Danish study. I posted a link to it here:

No need to regurgitate information I have already posted.
I would have to see data that supports your score-keeping in order to agree with your statement.

What is your problem? The topic of this thread isn't global warming.
