That reminds me, has anybody tried to do the math on climate change ?

The main effect is (probably?) going to be the thermal expansion of
the worlds oceans.

I did a quick back of the envelope calculation modeling the earth
as a sphere radius 6367 km, covered by a 4 km thick shell of water.

Increasing the thickness of the water by one meter but retaining
its mass, I get a realtive change in angular momentum of 6e-11 which
is in the order of a millisecond per year.

Never attribute to malice what can adequately be explained by incompetence.
