‘If Ryskin is right, then climate change, predicted to alter the strength and course of ocean currents, could also alter the planet’s magnetic field. ‘

Catastrophe or hollow earth ping.

Interesting theory.

Seems a bit too easy to test, however, for someone not to have discovered it before.

[jnsun]

An intriguing thought to say the least.

Although perhaps not the core mechanism, a bunch of free ions swarming across magnetic lines are going to alter or create fields otherwise not extant.

Good to see the idea coming out of the US. We're losing it fast - all lawyers, no science. Kind of like Barack Obama, Hillary Clinton, Charles Schumer, Barbara Boxer, Nancy Pelosi, Rahm Emmanuel, etc. etc. etc.

The magnetic field protects us from radiation;the ocean currents control the magnetic field; global warming is killing the ocean currents; man is causing global warming; therefore, we are killing ourselves.

Expect this to be the newest battlefront with the global warming nutjobs.

I metal detect and the movement of salt water definitively generates electric fields. It affects the fields put out by metal detectors enough that you have to have a certain type or at least have the right settings. It makes sense. There’s an awful lot of sea.

If I recall correctly, Mercury also has a magnetic field and not a heck of a lot of oceans.

Jupiter, Saturn, Uranus, and Neptune all have magnetic fields too, but are all gas giants and not really comparable.

	Gods Graves Glyphs	Thanks BGHater. Earth's magnetic field, long thought to be generated by molten metals swirling around its core, may instead be produced by ocean currents, according to controversial new research published this week. It suggests that the movements of such volumes of salt water around the world have been seriously underestimated by scientists as a source of magnetism.

Does it have to be either/or, or can it be “YES!” to both?

Wouldn’t be that surprised to see the ocean scenario as a contributing player.

Should have seen the “erosion” readings I got from a slurry sample decades ago.

I used a probe in a water/ore-particle slurry that was connected such that the hesitance of the probe was monitored, with the resistance change as the probe wore away being used to calculate the projected erosion of pipeline to carry the slurry from an iron mine to the mill. Problem was, the slurry was rotated past the probe in the vessel, and it contained magnetite.

Rotating magnetic particles and a steel probe = generator! The engineers I was working for had to design a new test method.

This could be a somewhat analogous macro-situation.

That would explain why so many people are drawn to the ocean...
