What Is going On Inside the Earth?

From the ESRF web site:

Scientists have determined the temperature near the Earth’s centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. The scientists were even able to establish why the earlier experiment had produced a lower temperature figure. The results were published on 26 April 2013 in Science.

When people talk about climate change, they talk about ice melting, glaciers, pack ice and permafrost. They talk about changes in the weather, flooding and drought.

I haven’t come across much discussion about what heating the planet may do with the inside of the Earth. The temperatures are very high so a rise of 1.5 degrees Celsius may not seem like much.

I am wondering if there is any link between climate change and increased seismic activity / volcanic eruption.

When things are at a balance point, a golden spot, near an equilibrium, it does not take much for things to start to oscillate wildly…

A few more cracks at the surface and the hot stuff inside might want to get out and perhaps in a spectacular fashion…
