Who thinks our planet is warming from within?

Question

We know that our planet act like a giant dynamo (metal core, and magnetic field), and that our climate is sensitive to geological activities as well as geomagnetic activities in the Ionosphere. So if the sun magnetic storms occurences increase, it could also affect our planet core (as our sun will act a little like electric power on a AC motor), thus warming our planet from beneath the oceans and water bodies...

Can it be responsible for our current global warming crisis?

As for solar radiation responsible as for the whole planet climate... Water bodies are all responsible for the warmed feel on this planet, and if green house effects were really working, only higher altitudes would feel the heat differences, and since thermodynamic laws prevent a cooler body from warming a warmer fluid, it could be impossible for such heat to be transfered to lower altitudes thus the thresold needed for a green house effects to affect lower atmosphere is almost impossible to reach, as it would means that temperatures at 10000 feet would need to be as much warmed as at 30 feet high! Which is far from being recorded yet... As far as I know it makes about 70C below zero at 14000 feet to 20000 feet high... Well for me it doesn`t look like ALL the planet is warming, only lower layers... And yet I did not talk about fluid viscosity and density...

Also it may not warmed up as we know it, but there is definitly something up in the air, with all this geomagnetic activities that could mark a greater activity cycle. I also believed that earth may be warmed from underneath water surface, as greater geologic activities look like to affect marine currents (like El Nino), and activities on this side have shows dramatic changes in their dynamic and occurences thus affecting the overall convectivity influences of those currents....

Irv S I got a sense of proportion... I guess you forget that our planet is turning on herself and that she is expose to radiation only on half of its surface... Which means that convective effects on earth DO have great influence in heat distributions over the globe! Also, if you never know the differences between a convection oven and a traditional one, then you clearly not understand what I am talking about! Since this topic is so wide, its not really possible to cover all the points here... But never hurt to get others opinions...

Answer 1

There isn't any doubt that heat from the interior of the earth contributes to the surface temperature, but the amount of such heat flow doesn't vary by much. So it is not nearly as good a candidate for surface temperature effects as are things like sunspots. Some work has shown a noticeable correlation between temperature and sunspots, although the data doesn't go back very far as sunspots are a recent discovery.

Answer 2

Correct, the earth's core is warm and actions of other bodies make it warmer.

When the moon rotates around the earth it stirs the molten core of the earth making it warmer. The same, on a smaller scale happens as the earth rotates around the sun.

The planet Jupiter has a very hot, very small moon called Io. Io is very active with lots of volcanoes because its rotation around Jupiter stirs its core and heats it up.

We are glad that the earth's core is molten because that's what creates the magnetic field which protects us from a lot of solar radiation. If the earth lost its magnetic field then the sun’s radiation would all get through and it would sterilize the planet.

Magnetic force is not that powerful of a force, and it doesn’t reach across a long distance very well. The earth is 93 million miles from the sun so the magnetic field of the sun doesn’t do a lot to the earth. It is the gravity of the sun that holds the earth in orbit and has the strongest power.

The magnetic field of the sun is responsible for sunspot activity and inside of sunspots the sun’s magnetic field changes.

However what started the earth’s molten core and is the major force that keeps it going liquid is the amount of radioactive substances in it. When a radioactive substance gives off its radiation it decays and generates heat. The earth has a lot of heavy metals in its structure, unlike our moon, and most of them are at the core. When you get metals that are real heavy, the nucleus doesn’t hold together very well it decays. It decays giving off radiation and letting pieces of itself fall off. This process is called radioactive decay.

Water evaporation is caused by sunlight not by the heat of the earth. However, mining is very hot work since the temperature of the earth goes up about 1 degree for every foot of depth. Therefore in a mine 3 miles down it is like a sauna. This is because the earth’s crust is thin and floating on a molten core. When you get down 3 miles you are getting real close to the molten core. Most of the earth is molten. If the earth was the size of a basketball then the dimples on the ball would be the mountains on the earth and all the air inside would be molten rock. The crust would be thinner then the shell of the ball. If you dropped a drop of sweat on the ball and wiped it off then that thin film of water that remains would be the atmosphere of the earth. Over 90% of the earth is molten rock hotter than the hottest lava. We live on this very thin and tiny crust. The crust is broken into a few pieces; tectonic plates that float on its surface; almost like the film on cooling soup. As the tectonic plates float around they move. When they crash together you get mountains, when they slip and rub against each other you get earthquakes and when they slip apart or have holes we see volcanoes.

Luminescent clouds like the Arora borealis are the action of solar radiation hitting the earth’s magnetic field. We see the glow as some of these particles are spent in the atmosphere. Your article says: "These observations suggest a connection with global change in the lower atmosphere and could represent an early warning that our Earth environment is being changed." Meaning that global warming is the probably cause, not the heating at the earth’s core. Remember we are adding more CO2 to the air and that is the biggest change being made to our atmosphere recently. I had problems finding all of your other citations because they were either taken down or moved.

Actually the Earth’s core is cooling, slowly and it is cooling even slower thanks to the moon; but our earth’s core is cooling and the atmosphere is getting hotter due to global warming; which is an effect of the Greenhouse Effect, a well known effect.

According to Wikipedia: http://en.wikipedia.org/wiki/Structure_of_the_Earth
“It is generally believed that convection in the outer core, combined with stirring caused by the Earth's rotation (see: Coriolis effect), gives rise to the Earth's magnetic field through a process described by the dynamo theory.“

This is that dynamo or motor part of your question and it is the reason why the tectonic plates can move, the molten rock is being stirred.

I think you are trying to support an argument that global warming could be caused by the earth’s core heating up. That could be a factor, and it might have created warm and cool periods in the past. However, the greenhouse effect is stronger and is having more of an effect on us than the warming of the earth. Besides if the earth’s core was warming as much as you think the temperature at the bottom of the oceans would be much warmer. That would change the sea life as we know it and it would change the normal convection currents in the ocean. If that were to happen then we would see the effect on the surface of the water, not in the atmosphere.

El Nino happens for an unknown reason. It is relativity near the ring of fire so warming of the earth beneath the ocean could be a cause for it; we need to do some more study on the situation.

The main point here is the earth is warming from the outside in. It has been cooling from the outside in for all of its life. Now that the greenhouse effect is changing things the atmosphere is warming up.

Interesting theory, but you lack the support for it and global warming is much more likely caused by the increase in CO2.

Answer 3

The planet is not warming from within. All the heat that it is being released is from the intial accreationary heat (when the earth formed). Radioactive decay does not play a role in this either because it is so minute

Answer 4

Get a sense of proportion.
The effects you cite are miniscule compared with insolation/radiation.
