Ah, has anyone considered radiogenic heat? Of course, there's nothing we can do about radioactive decay below Earth's surface, but have you thought about how much heat is being produced by all things nuclear topside?

Wikipedia:
The radioactive decay of elements in the Earth's mantle and crust results in production of daughter isotopes and release of particles and heat energy, or radiogenic heat. Four radioactive isotopes are responsible for the majority of radiogenic heat, uranium-238 (238U), uranium-235 (235U), thorium-232 (232Th), and potassium-40 (40K).

The flow of heat from Earth's interior to the surface is estimated at 47 terawatts (TW)[1] and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth.

Radioactive decay accounts for half of Earth's heat

Just for completeness, in case someone wonders about other factors, the contribution from another nuclear source - the decay of radioactive elements in the Earth's crust (40TW) - amounts to near 0.1 W/m2 which is much more significant than the waste heat.

Fukushima, Chernobyl, Cold War nuclear weapons testing, present weapons testing, nuclear power plants, nuclear dump sites, open, abandoned uranium mines, coal fly ash - it's radioactive...etcetera...What kind of impact does all of this radiogenic heat have on global warming?
