The Earth's core has stopped spinning faster than the surface

[wellwisher]

I read an article yesterday in MSN news yesterday about the core of the earth. It appears to have stop spinning faster than the surface.

Earth's inner core may have stopped spinning – but what does that mean?

About 20 years ago a team of scientists, using seismic techniques and live and historical data from earthquakes all over the earth, discovered the core of the earth was spinning faster than the surface of the earth. It was calculated that the core lapped the earth, once about every 500 years. This is slow but still orders of magnitude faster than the movement within plate tectonics. There may be a connection.

This was an amazing discovery, since the iron core accounts for 30% of the mass of the earth. We are talking about a huge metal ball, inside the earth, having more angular velocity than the mantle and crust, which combined accounts for remaining 70% of the total mass.

More recently, this new article; above, says scientists have now discovered that the core no longer appears to be spinning relative to the surface. If you consider its huge mass and inertia, the question is where is the energy going, since stopping that huge amount of inertia, will need either a loss of forward thrust and/or a huge resistive force. The bottomline is the energy balance of the inner earth has changed drastically; kinetic to heat or magnetic to kinetic. Can this affect climate? Will the extra heat, warm the oceans and cause CO2 to be released.

I have been complaining for years how Climate science is stuck in the science past, and is not up to the task in terms of the many latest inner earth discoveries. Scientists seem to think this change in the core is not unique, but is part of a natural cycle and that the future rotation of the core may even spin the other way . Will that cause crustal surface stresses.

My theory is water is continuous from the atmosphere to the core of the earth. This theory is based, in part how water increases the entropy of earth materials as temperature and pressure increase; solubility increases. It also has to do with the phase data of water, at extreme pressure and temperature. This data shows distinct phase boundaries that align with the layers of the earth at their assumed temperature and pressures. The extreme conditions of the earth's core, water becomes a solid metallic phase.

The phase boundary between the outer core and core would be based on a phase change of water from ionic to metallic water. The hydrogen protons of the water corrodes the metal iron core and releases energy and electrons, to the ionic water phase, at the phase boundary. The slowing of the spin would mean there is a lull in the flow of exotic water and hydrogen to the metallic core. Green houses gases may be the least of our new worries. Will days get longer if the earth's core spins the opposite way?

Maybe this will allow us to read the days of Genesis in a whole new light?

When is a day not a 24 hour day? I have long wondered at the forces that determine the rotation of the earth.

This sounds like a Futurama episode.
Evil cats were the cause.
We need Amy Wong to rescue us from this carnage!

Will the days get shorter if the momentum of the core is transferred to the rest of the earth?
Is it a cycle, a transfer of momentum in one direction (core to rest of earth) and then back again?
Is it something else?

It's not really a day is constant.

O is a 24 timed spin.

As when wasn't a day was when we owned no heavens ...and no heavens no human.

O mass travel is 365 of 24 hour duration. Rotations. Not a day.

Is when a day isn't a day in the same experience.

Life at poles doesn't experience a day like life does elsewhere.... yet all humans are on the same planet.

It's what you realise when you think about our life's variables upon a planets mass. That advice says already a human in knowledge isn't owning the same day experience as I am.

About poles and ice and heavens position by planetary mass.

To say I am using comparing my human ideas why a day could be experienced as a variation.

As what a planet does no human controls.

I'm sure we humans have had some pretty horrific earth change experiences before. It's why we worry.

The one I read last night said its reversing.

I suspect the validity of the conclusion. However, I suppose that at some point the internal material of the planet will stop rotating faster than the external material, and they would sinc up. But given that the core is still very dense, and still molten, I doubt that time is now.

 

[beenherebeforeagain]

Has the core's rotation really slowed in the last however many years since the first measurements were taken, or have the later and better measurements really showed that those initial conclusions were off by a bit?

The direction of the inner core’s rotation may be reversing

"We see strong evidence that the inner core has been rotating faster than the surface, [but] by around 2009 it nearly stopped,” says geophysicist Xiaodong Song of Peking University in Beijing. “Now it is gradually mov[ing] in the opposite direction.”

So the authors interpret their data in that way...there may be other ways to interpret the data...I expect more studies with the possibility of disagreement with the conclusions of this study...

Which is absolutely how science should work!

The core of the earth is assumed to be mostly solid metallic iron with some metallic nickel. It weighs about the 1/3 of the total mass of the earth, which, to put in perspective, is about 10 times the mass of the moon. This is a large heavy object that was spinning.

The core is this huge massive object. I would take lots of energy to make it rotate and/or make it slow down. Where is the energy coming from? When it slows down does it generate brake heat that heats the inside of the earth? This brake heat would be huge. Does this heat eventually reach the oceans, thereby leading climate change, since warmer ocean water will release CO2?

The geological evidence can show that earth naturally heats and cools in cycles. Now we have a massive core that is 10 times the mass of the moon, appearing to have cycles in terms of spin direction. How does climate science takes this into account. or do they still use old earth science assumptions?

I would be less concerned about the days getting shorter or longer and more about the heat and stresses that this huge core object may apply to the surface, as it changes direction and then starts to speed up. If the day period was to change the crust would see stresses as the surface inertia changes.

If you have a spinning object, there will get tensile stresses on the surface; tectonic plates will spread apart. If it was too slow, the tension lowers or compression increases. Will the mountains start to grow? This could explain why the ocean have not risen as expected; land is rising.

The mass density of the core, has an enhanced gravitational pull that is stronger than in the mantle. The core pulls what is above it, toward it. How does the core avoid friction so it can spin, since its stronger gravity is pulling material toward it and not allowing the core free space with zero friction? There should be lots off friction and heat whether it spinning or slowing. The old school reasoning for the heating of the inner earth was radioactive decay. That does not explain the energy needed to spin the core.
