It is surmised that the cooling rate is unalarming, and very small, with century as unit of time: #0.0001^oC#/century


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



Perhaps, it might go down by #100^oC# to #5900^oC#, after 1

billion years.
