Furthermore, by knowing the mass of a planet from radial velocity measurements and the radius of a planet based on how much starlight it blocked, it is a simple calculation to determine a planet's density, which can tell astronomers whether that planet is rocky or gaseous in nature, or whether it has a small core and a thick atmosphere, or whether it has a large core covered in deep oceans.

Now the locations of avaialble proxy data (tree rings, ice cores, ocean sediment records, corals etc.) are not necessarily optimally spread out, but the spatial sampling error is actually quite easy to calculate, and goes into the error bars shown on most reconstructions.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

The author speculates that since it is liquid the outer core is also affected by gravitational tidal forces, in a similar manner to the oceans, but also it can be assumed that the magnetic field generating would act as a brake on its movement.

While part of the tidal energy is dissipated on the coasts, another part turns into the circumpolar current and is ultimitely dissipated on the ocean floor, and that current could be reduced or eliminated if the Strait of Magellan froze deep, reducing the rate of deceleration and allowing the core to catch up a little (in its deceleration).
