I, myself, am more inclined to believe in the cooling in the mega trend. The same group of scientists, when pressed, have a theory that the Earth, at its forming some 4.6 Billion years ago, was a very hot place — hot enough to have liquefied rock at the surface — and was named the Hadean Eon. So, how was it able to cool itself down so that it could support the various arrangement of life it has today? Chemical transformations where the most dense material sank to the core while much of the less dense material remained at the surface and continued to give off electrons in a radioactive (non harmful particle) decay the expended a lot of heat. This radioactive decay is now happening at a slower rate, with less and less heat being generated at the surface. While this process does not have as much of an affect as our sun, it does have a significant affect the is decreasing in its impact.

...and was named the Hadean Eon.

Who was here to name it that?

Is this like that horse in the desert thing?
