Hi all, I have been wondering about this for a while. Is the oil that is being drawn out from the earth there for a reason and helping keep the earths core cool? Is the earths core heating up (how would we know) and causing global warming?
Just a though, what do you think/know?

| Dang man, thats some far out crap. The answer to your first question is likely no, but you may want to look into that second one. It is possible that geothermal heating is melting the ice cap on Greenland. |

Yup. The real cause of global warming is that the earth has gone beyond it's 3 billion mile oil change. (We should probably change the air filter while we're at it too.)
I'm afraid your post reveals an impressive cluelessness about basic physics. |

Let's assume there is 10 trillion barrels of oil in the world, OOIP. That's about 1500 cubic kilometers. The Earth is about 6000 kilometers in radius (V = 4/3pi(r^3). That would be more than 1 trillion cubic kilometers. Nearly all of the Earth is rock, which would require more energy to heat up than petroleum. How could petroleum possibly have any detectable influence on the core of the Earth, which is 3,000 kilometers away (outer core)?
One of the fun things about studying geology is learning the amazing size of the Earth. We see but a tiny tiny fraction. That 99%+ of our learning and books surround just a small fraction of the Earth is amazing. For instance, it's be estimated that there is 3-4 times as much water INSIDE the Earth than is in/on the crust, due to subduction zones?

I haven't read up on that, but I'm pretty sure that the numbers don't add up.
2.85 million cubic kilometers. That's 2.85 quadrillion cubic meters. The density of ice is about 1000 kilograms per cubic meter so then that's 2.85 sextillion grams. The specific heat of ice is 4.1813 J/(g*K). So to move up the Greenland ice sheet by 1 degree Kelvin, that would require about 10 sextillion Joules. Unless if I've done my math wrong, that's equivalent to 2000 Tobas. If you don't know what Toba was (70,000 years ago), it was an ultra-plinian volcano which was 50 times as large as Mt. St. Helens.  Large enough that it almost wiped out the human species!
I'm no geophysicist, but I'm pretty sure that kind of tectonic or volcanic activity hasn't been happening in Greenland lately.

And I'm afraid your post does nothing to help the person, rather you seem to mock him. That will get us nowhere. At least try to explain how their wrong, even if you don't want to go into the gritty numbers.

Oh yeah, and could you check the water while you're at it.

... and the anti-freeze is definitely running low and needs to be topped off pretty quick.

I'd say the attention should be focused on the hairless parasites that appear to be breeding incessantly and causing all sorts of unfortunate symptoms.

"And I'm afraid your post does nothing to help the person"
I thought about doing a serious post but I couldn't get past "Where to begin?" A discussion of mechanisms for heat generation and thermal transport in the core? A discussion of radiant heat balance mechanisms in the atmosphere? A curt statement that he should spend some time with the FAQs?
It was obvious that he was working from analogy, "When the oil gets low in my car it overheats". |

As mentioned above the numbers dont come any close to adding up. But what gets me is the reason bit. Are you suggesting god put oil there for a reason? Did the earth decide to do it? Pretty crazy stuff man.
Still though this site is a treasure trove of information. Try lurking around for a bit first. Theres some genuine diamonds amongst the rough. |

IMHO you are not being fair to the OP. If you look at the Earth as an operating system, I think he asked a very logical question. For any system to work optimally, all of the parts need to be too. The OP is simply looking outside of the box. Every discovery begins as a question.
Stepping off the soapbox. OK- flame away.

If you believe the mainstream opinion that oil was formed some time ago, long after the earth's formation, it does not make much sense, really. Also, I don't really know how much heat taking capacity crude oil has (I suppose it's a lot), and I can't really see where would the thermal fluid (oil) be transferring it's heat to - if I understood well, your idea was that oil was working as a radiator.
In a way, you are right: keeping oil underneath, unburned, keeps all that carbon from being released into the atmosphere as CO2, therefore essentially holding GW.

Welcome to peakoil.com Gavin.
Our members will now proceed to bash you mercilessly.
Sorry about that.
Guys, a little kindness would kill you?
Sheesh...
tough room.

Wow! That's breathtaking... Reminds me of the following post that I recall from 2006:

Earth has a natural mass. Does the mass have anything to with how and where we orbit the sun, our rotation (day/night cycles). Now I am wondering if mass loss from the earth will have any effect on the earths orbit. Consider we throw millions of tons of marterial into space, making the earth lighter. We extract million, maybe billions of tons of oil and NG out of the ground and do nothing to replace this mass and its gone when we burn it.
Kinda like we are lighter now and get pulled towards the sun, or lose our orbital inertia and end up flying out of the solar system totally.
If you took all the material we have burnt to nothing. Ejected into space (off the earth physically and thus a mass loss) in satellites etc... would that have any impact on the earths ability to maintain its rotational orbit around the sun un-impacted?
Can we screw up earths orbit causing it to fly out of its orbit or stop rotating within its orbit, by lossing mass of the earth? I am just wondering if maybe we are killing our planet in an unobvious way. I can see how we are killing our planet ecologically speaking. But what about astronomically speaking. Anyone have any insight to this or does earth mass not play into the orbital equations. |
