A great deal of money and time is being devoted to solving the mystery of Earth’s missing heat. But perhaps climate boffins are looking in the wrong place? Perhaps the missing heat is hiding along with missing water and missing hydrocarbons — under the crust.
A tiny crystal found in a diamond has confirmed predictions about a giant store of water deep in the Earth’s mantle. The rock is the first direct evidence to back up theoretical models made over 20 years ago, and suggests the vast underground ‘reservoir’ – 500km below Earth’s surface – could hold more water than all the world’s oceans combined.__ Chemistry World

When oceanic crust converges with continental crust, it subducts beneath the continental boundary — taking large amounts of water, organic material, and hydrocarbons along with it. A significant amount of heat goes along for the ride, but not enough heat to explain the inconvenient ongoing hiatus in global warming.
The subducted water plays an important role in the formation of volcanoes. Subducted organic matter and hydrocarbons play an important role in the evolution of mantle and deep-crust carbon.
This dynamic recycling of water, hydrocarbons, and oceanic crust is driven by the engine of plate tectonics.
Besides the resulting earthquakes, volcanoes, tsunamis, and other natural phenomena, the recharging of oil & gas wells by hydrocarbons in the mantle is of potential economic importance.
As for the “missing heat,” climate boffins will need to continue scratching their heads. Every “explanation” they have come up with so far reeks with the stench of desperation and implausibility. The next thing they will likely claim is that the missing heat is hiding inside Earth’s molten core.
The sad truth is that Earth’s dynamic chaos cannot be captured by any man’s computer model, mental model, or artificial ideology. Real scientists love a mystery and are not so eager to shut off debate.

Wikipedia: Expanding Earth Theory This Wikipedia article attempts to look at the competing geological theories from a “weight of evidence” standpoint.
Here is the interesting thing about this geological debate: It is open to anyone who can present better ways to explain the evidence, or better ways to accumulate new evidence. Sure, opinions run hot and sharp in geology as in all sciences and human endeavours. But without the interference of the heavy cold and fatal hand of national and international politics, most geologic debates take place openly and honestly — unlike the artificially closed debate in “climate science.”
