Earth's internal engine is running about 1,000 degrees Celsius (about 1,800 degrees Fahrenheit) hotter than previously measured, providing a better explanation for how the planet generates a magnetic field, a new study has found.
A team of scientists has measured the melting point of iron at high precision in a laboratory, and then drew from that result to calculate the temperature at the boundary of Earth's inner and outer core — now estimated at 6,000 C (about 10,800 F). That's as hot as the surface of the sun.
The difference in temperature matters, because this explains how the Earth generates its magnetic field. The Earth has a solid inner core surrounded by a liquid outer core, which, in turn, has the solid, but flowing, mantle above it. There needs to be a 2,700-degree F (1,500 C) difference between the inner core and the mantle to spur "thermal movements" that — along with Earth's spin — create the magnetic field.

Didn’t Nobel Prize winner Al Gore tell us that the temperature of the earth’s core was millions of degrees?
“The earth has a feevah!!”
And the only prescription is MORE COWBELL!
Yeah, but he’s a fat sex poodle.
Fun fact: Water freezes at 32 degrees, and coincidentally, that is Al Gore’s IQ.
Global warming from the inside out! It is likely that the Earth is underway on nuclear power. ;-)
Hey Norm—ya reckon hades is expanding as well to accommodate new environs? The carbon footprint down below must be an environmentalists nightmare, eheheh.
But it’s a dry heat.
So what is the stuff at the core that remains solid while surrounded by 10,800degF+ degree stuff?
At these temperatures and pressures, known materials behave as fluids, right?
You can find that talk by mashing: here.

I read the article. Nevermind.
The pressure of the inner core keeps it solid despite the temperature.
But the cause of the heating never gets it’s proper due - radioactive decay. Without it, earth would be dead.

Are you sure it works that way?
Mankind has been ruining the planet from the inside out!
31+ here today.
It is finally starting to warm up.
But, we got snow again yesterday.
Oobleck seems like a liquid, but breaks like a rock when you hit it with a hammer.
Cooks study this stuff.

OMG...you poor thing.
