Here's another interesting little fact about one of the co-authors of the Humphrey's paper. John R. Baumgardner, of Los Alamos National Laboratory, co-authored this paper in 1998

Time Scales and Heterogeneous Structure in Geodynamic Earth Models

Hans-Peter Bunge,* Mark A. Richards, Carolina Lithgow-Bertelloni, John R. Baumgardner, Stephen P. Grand, Barbara A. Romanowicz

Abstract: Computer models of mantle convection constrained by the history of Cenozoic and Mesozoic plate motions explain some deep-mantle structural heterogeneity imaged by seismic tomography, especially those related to subduction. They also reveal a 150- million-year time scale for generating thermal heterogeneity in the mantle, comparable to the record of plate motion reconstructions, so that the problem of unknown initial conditions can be overcome. The pattern of lowermost mantle structure at the core-mantle boundary is controlled by subduction history, although seismic tomography reveals intense large-scale hot (low-velocity) upwelling features not explicitly predicted by the models.

What sort of ethics does a scientist have, when he can on the one hand author papers claiming the earth is no more than 6000 years old, and on the other author another that discusses geological processes over a 150 million year time-scale? Which of the two papers he co-authored does he not actually believe?

He believes the 6000 year time scale. His computations indicate a 150,000,000 scale. Cf. the White Queen.
