I've got two questions, maybe someone here is familiar with such things. First, in all these theories is any thought given to how much heat is radiated from the earth's interior?

Any studies of this? Is it assumed to be steady and slowly decreasing? Could it cycle? Maybe local heat chimneys? How much surface heat comes from interior heat?

And second, why are our oceans so cool? They are held in a very warm, radiant cradles. I can not believe that the pole flows are cooling and maintaining the ocean temps.

That leaves evaporation. When one realizes the amount of heat removed.....it's quite a dynamic.

A large temperature buffer. Maybe the depth(or volume) of cold water would be a great indicator of climate strain.

... during the late 1800's ... something like that ... the big scientific question was what was the age of the earth. ... Lord Kelvin ... and others tried to model the earth as a ball of clay or similar material, subject it to extreme heat, and then calculate or observe how long it took to cool down, thereby obtaining a rough estimate, an approximate time interval for how long the real earth would have taken to cool down from its original molten rock origin. The results were off by several orders of magnitude too young because they were not cognizant of the heat produced by radioactive decay in the earth's interior. ... a similar calculation for the age of the sun was also incorrect due to an insufficient understanding of the nature of the various reactions going on in the sun's interior.
