Global warming, meteor impacts, super volcanos, can cause or end ice ages, how has this affected the relative orientation (like the lead weight that keeps you car/truck tires balanced) of the planet, seeing as how the ice caps are melting, I have heard at one time true north(not magnetic north) was over northern Germany, at some point in geological history it shifted to somewhere over hudsands bay, at around tenthousand yrs bc, it shifted again to where it is today, with the warming trend, the poles are not the only thing melting, the glaciers too are going, how has the displacement, from solid and above sea level, to a rising sea level, affected this balance, I ask cause the boxing day tsunami event caused a redrawing of the map, and a orientation adjustment for the GPS system, also green land reports the sun rise was two days early... The only way is can see this being tested is with a super computer, a very accurate topographical map, and up to date glacier maps, some forecasting models might help.
