If we're getting our stories from The Daily Mail, what about the inevitable Muslim takeover that will destroy the world first?

t3knomanser: THE GREAT NAME: Clearly the effect of a few decades with virtually no magnetic field to protect our technology is a much bigger deal

First, this process is not a "few decades" long. It's thousands of years. Second, There is no evidence that the Earth will be without a magnetic field for this period of time- to the contrary, our best evidence indicates that the Earth's magnetosphere remains roughly the same.

This isn't a matter of talking anything "down". There's no evidence that indicates any sort of alarm is necessary or helpful here. Further, unlike climate change,  there is literally nothing we can do. The biggest vulnerability to solar radiation is the power grid, and it is  impossible to harden it sufficiently to operate without the Earth's magnetosphere for protection. Further, since there's no evidence that it will be called upon to do so, it's foolish to seriously consider it  anyway.

What we do know is that the weakened field allows solar radiation to reach the upper atmosphere. We know this because of radioisotopes gathered from 40,000 year old ice cores (the same ice cores that allow us to measure the relative quantity of CO2 in the atmosphere). We know that there's no correlation between mass extinction cycles and geomagnetic reversals, implying that there's no organic danger due to radiation. We know that geomagnetic activity is chaotic and seemingly random (it is emphatically  not periodic, and it's wrong to say we're "overdue" for a reversal). We know that the process is  usually slow, but it can sometimes happen very quickly- the 40,000 year old Laschamp event happened over the course of less that 500 years. The Cretaceous Superchron lasted 10 million years.


We really didn't have any strong earthquakes in the 70's, 80's, and 90's. Then the large ones started to become more frequent; 2004 9.1, 2005 8.6, 2007 8.5, 2010 8.8, 2011 9.0, 2012 8.6.

The 2011 earthquake reportedly moved the Earth's axis 10 inches, which caused a little warming in the oceans. In my neck of the woods we saw two years of record rain and are still in an odd weather pattern.

 I was reading where the Earth has two cores, one inside the other, that move in opposing directions, but they have changed direction in the past. Now we have news the magnetic flux lines are past due to change direction, but this is wrong? When the Earth's poles change - it'll happen at the speed of light, wouldn't it?

If the Earth is a big rotary machine that periodically, "glitches", is it wrong to look for correlations and prepare for the effects, no matter how minor?  Seems odd that we build super computers for people that don't know what to do with them, kind of like building calculators for cows. I'm a cow, a big one. How do brown cows eat green grass yet give white milk? This is a strange planet.

Smoking GNU: The magnetosphere isn't collapsing, it's loosing integrity to a small degree as it moved towards a probable pole shift. Magnetic iron deposits show that this is a somewhat regular occurrence and that the magnetic field weakens before such an occurrence.


Get dat nerd shiat out of here!

It's absolutely true because I read it in the Daily Mail.

My 12-year-old just did a school project on this, and despite his fondness for zombie apocalyses and comic-book physics, he sounded more rational and sciency than that article.

He also presented a solution in the form of massively decentralized DC power grids.

That's not exactly true. USGS data for all 8+ quakes since 1970. While activity has increased recently, a forty year window is peanuts to geology. When you expand the time horizon, you see that it's not really that big an anomaly. The 1960s had a nice pile of big quakes.

Ficoce: The 2011 earthquake reportedly moved the Earth's axis 10 inches


Ten centimeters, not inches. Big difference.

Ficoce: When the Earth's poles change - it'll happen at the speed of light, wouldn't it?


No. The Earth's magnetic field is generated by the extremely complicated motions of the iron core and the mantle. The idea that the Earth is a dipole is misleading- the Earth is a massively multipole magnet, that averages  out to a dipole, most of the time. What happens when the poles shift is that some of the other poles of the magnet become stronger, some weaker- zones of "north" can appear along the equator. It's a chaotic event that takes a long time to resolve itself.

Wen need to wind electric wire around the equator and build a shiattons of power-stations, so we have a giant coil we can power up to revert the magnetic field when this happens.
Simple!

Triumph: namatad: I predict that sooner or later the GW deniers will notice this fact

What fact? That the poles are about to swap? That's a fact now? That was fast.



1) thanks for quoting me out of CONTEXT and then being confused about what I said!!

2) what I said:

I predict that sooner or later the GW deniers will notice this fact and start pointing out that the earth was warming during the same period that the field was weakening!

There are actually TWO facts here:
1) The earth has gotten warmer over the last 200 years.
2) The earth's magnetic field has weakened over the last 200 years.

there is little or no contention over these facts. (contention over the cause of the warming and the magnitude is not even relevant to the fact that warming has occurred)

STUDY IT OUT!
CORRELATION OVER CAUSATION 

/yes, I am being "sarcastic" about what happens next to facts. but people using facts incorrectly does not change the facts.

STRANGE!
All of those big earthquakes happened near coast lines!
I think the earthquakes might be caused by the increase in population! Especially near the coasts.
NYC is due for a huge earthquake any day now.

lilbjorn: Isn't almost every scary scenario they cite actually what would happen if the magnetic field were growing stronger?


Almost certainly not.  I didn't actually read it, because, you know, daily mail, but if you multiplied earth's magnetic field's intensity by 10, the only change that would be required is recalibration of some aeronautics equipment.

THE GREAT NAME: Ha ha I love all the global warming alarmists trying to talk this down because it's not man made.

Clearly the effect of a few decades with virtually no magnetic field to protect our technology is a much bigger deal than a few flooded coastal areas. But there's no "your sins caused this" angle, so they're not interested - in fact they want it to go away because they want all the media "science bandwidth" to be spent promoting their pseudo-scientificreligion.


Yeah, let's send Sandra Bullock to plug a car battery into the pole, that'll do the trick! Just like in that totally scientific documentary The Core!

Meanwhile, we -can- maybe not burn so much shiat or do something to offset incoming sunlight if it comes down to that.

That's still going to be a PITA socially, and depending on how the poles shift could cause havoc. But on the other hand, there's jack all we can do about it anyway.

2014-01-28 05:09:36 PM  
*facepalm* Scientific American had the polar shift as a cover article back in 2004, and as it's already been mentioned, iron deposits show that this is a typical (though infrequent) event that takes hundreds of years to complete 1 shift cycle.   The Taoist in me perceives this as the magnetic poles are always in the process of shifting, and have never been solely stable.
 
2014-01-28 05:16:54 PM  

t3knomanser: All the geological evidence we have indicates that while the field becomes more chaotic, the magnetopause still extends out to 3 Earth radii and will continue to protect us. This has happened many,  many times before. There is no evidence that links reversals to any sort of cataclysm on Earth. If there  were a sudden influx of radiation, we'd expect to see mass extinctions- and we don't.

The process also takes 1,000-10,000 years, so... what I'm trying to say here is that this is a non-event.


Nooooo! It's gonna happen tomorrow because I didn't buy a hybrid!

/glad someone finally pointed out this process isn't really "instant" relative to our lifetimes.

Consider the following:
The simplest life on Earth formed approximately 3.6 billion years ago. 0.2 billion years later, cyanobacteria was around. Using the average occurrence of 450 thousand years, the poles would have reversed approximately 400 times in the time simple cells would have evolved into cyanobacteria. I would think that magnetic pole reversals would have killed off life, via solar storm radiation, before it even had enough traction to get started.

You could argue that, in theory, the magnetic reversals may have spurred evolution from simple cells to cyanobacteria.

Any complex body capable of supporting life should be able to protect said life from events that occur repeatedly over a long time.
