Figure out the rotational moment of inertia of an oblate ellipsoid (stopping at the crust).

Then figure out the mass of the infinitesimal outer layer, as though it were composed of sap.

Neglect the uneven distribution of trees from continent to continent, neglect the oceans. (Hint: this is how climate science gets started, "the case of the spherical race-horse is very interesting.")

Then figure out if the overall moment of inertia changes by moving that shell out by about 30'.

Hint: I really doubt it.

But don’t you wonder how many of my listeners went home and told that to their families? As I think of it, I’m incredibly literal minded. WHAT IF HE WAS TELLING A JOKE AND I DIDN’T GET IT?

I doubt it as well. Plus there’s the melting snow settling to a lower elevation which would have the opposite effect. I would imagine the effects would be less significant than a freckle on a flea. But I could be wrong.
