the changing of the magnetic field

[Further]

SWARM satellites show weakening magnetic field and that the field is on the move

SWARM, a new 3 satellite system that was launched late last year that takes measurements of our magnetic field like has never been done before just reported it's first big bulk of data. It shows how the field is changing, getting weaker in some areas, stronger in other areas, but overall getting weaker. Also, it shows that the magnetic north is migrating towards Siberia.

Interesting, it's cool to see, but this is just the initial findings. THis new data will be scoured for more information.

I really hope the weakening field is an anomaly or bad data or something. Scary stuff!

Well the field does naturally do this every 2-600K years and then spends a couple centuries flipping and reestablishing itself, perhaps that's all it is. In a few hundred years we will be fine.

Oh, just a few?

besides revolutionizing the navigational supply market, what are the ramifications of this? mass extinction? mild inconvenience?

This question was brought up in a class a while back, and this is what I remember, but I'm sure there is more specific info.

mild effects but many. Rates of cancer, especially skin cancer will rise. Certain foods will become more difficult to farm and certain areas will be less arable. But in truth, it's nothing that will eradicate many, but if it continues we will be more prone to things that already affect us.

And navigational issues won't really be an issue either, it should all be predictable and slow enough that our computers should be able to compensate.

Denny's fault. Won't acknowledge global warming.

You're describing a pole flip. If the magnetic field completely stopped (which it likely won't happen before the sun explodes due to nuclear reactors in the earth's core) life on earth is fucked.

Correct, I was assuming it was related to a pole flip. I never heard anyone suggest it was related to a total stoppage, of which isn't expected to happen for billions of years.

According to NASA, long-term observations suggest the Earth's magnetic field is decreasing at a rate of about 0.07 percent per year.

"This means that in 1500 years from now, it will only be about 35 percent as strong as it is today, and in 4000 years it will have a strength of practically zero," the space agency says.

"Because the magnetic field is a critical buffer shielding the biosphere from cosmic rays and charged particles from the Sun, the health hazard posed by the Earth loosing its magnetic field is hard to comprehend."

talk about a slow and agonizing death.

Yes Denny, but that's only if it's linear, which I don't think most believe it is. A pole reversal is more likely which takes between 1000 and 10,000 years usually it weakens and will bounce back.

I went to K-Mart to buy magnets, but there's been a run on them and they're all out.

How old are you? Nobody goes to Kmart now.

First, you disparage Mexicans. I always defend the salt of the Earth.

Second, you must be a Wal-Mart fan. They donate to Republicans. Or you're a Targeter. That's better.

K-Mart still has some bargains.
