At what rate is the earths core cooling off? And how long will it take?
It is surmised that the cooling rate is unalarming, and very small, with century as unit of time:
Understandably, there appears to be no steep changes in the mean
temperature and pressure gradients, down into the core.
From surface to the center in the core, the climate averages might
rise a bit on the surface, and this has no influence on the
temperature and pressure, in the deep layers of the Earth.
As of now, the core temperature is estimated as about
A MON AVIS:
Perhaps, it might go down by
