Has Anyone Thought Of Earth's Magnetic Field And Global Warming?

I spent some time today on the road to Port of Spain in a taxi - getting the front seat both times. Since I wasn't driving, I had time to sit and think - and since I had the world passing around me as the rain fell all the way up the Solomon Hochoy Highway, there wasn't much to see. Except wires. Ever since I started tinkering with photography, I've become so very aware of all these wires. Wires here, wires there... it's hard to take a scenic picture without wires in it.

Rain. Wires. I'd forgotten my book on Benjamin Franklin at home, but I was remembering bits of it. And tieing them together with what Nikola Tesla later did along the lines of using that knowledge base toward developing the electric motor. And then recalling an experiment Tesla did with a mile long rod of iron buried in the ground which had a current induced into it from the Earth. Inductance. A magnetic field induces current in a wire. The Earth's magnetic field.

Earth's magnetic field. We don't talk much about that, do we? That the Earth has a magnetic field, that it induces currents over large distances in pieces of metal. And I read somewhere about magnetic field reversals being used in dating for geology. Brunhes-Matuyama reversal. Right, but the average time prior to that period for a magnetic field reversal is supposed to be about 250,000 years. Technically speaking, we've gone through 3 periods of 250,000 years so far without a reversal between magnetic North and magnetic South.

And then there's Magnetic Field Decay. Hmm. Airborne pollutants that are ferromagnetic would be attracted to a magnetic pole - North and South. That might explain the movement of the poles over the years - before we humans really even started with the pollutants.

It's not that they would deposit there; scientists probably would have found them in the sea ice. Or maybe they have. There was an OpenDepth post on Sea Ice - which pointed to All About Sea Ice. No data on that available without paying. I sure would love to know if over time there has been more or less ferromagnetic and paramagnetic materials landing on the ice cubes at either pole. If the sun hits something that absorbs heat, it could melt some ice around it. No data to prove that from this little keyboard. Diamagnetic materials would be deposited nearer the equator.

Winds. Water. Tides! Currents of water. Ocean current. Nope, nobody seems to have found a link between ocean currents and the earth's magnetic field. That doesn't mean much though, because deposited materials would accumulate based on their magnetic temperament and so forth - and would affect the net strength of a magnetic field. The way magneticly active materials accumulate in lava and ice is used to tell periods of time... and probably is a part of researching (get this!) the weather patterns of the past.

But nobody seems to be looking at how the Earth's magnetic field is being affected by pollutants, or how the magnetic field interacts with weather patterns - at least that I could find in one evening. Global warming, right? Pollution, right? OK. Yet... looking at all of those wires, I remember that with an induced current, a motor is a motor. Yet when a motor is mechanically spun, it induces a voltage - it's a generator. Dithering in between is inefficient, but happens all the time.

Are we dithering the earth more toward being a motor than a generator? There's a question worth considering... maybe because we haven't been considering it. We're moving little electrons around the world, and sure... every little wire doesn't mean much... but over long distances, underground, above ground... Everyone's obsessed with the Sun and the Earth's magnetic field dealing with global warming. Maybe we should be looking more closely here, too...

I don't know. I'm just asking questions. I know we could find out by looking at the data in that manner, and I don't know that we have. We've come a long way since Benjamin Franklin, but I don't know that we've retained his questioning and searching. After all, he mapped out ocean currents and he also flew kites in storms. :-)
