Melting ice caps.

As I understand it there has be a considerable reduction in the level of Ice at the Arctic but an increase of ice at the Antarctic.
Does the reduction in the North balance the increase at the South ? and could this change alter the axis of the earth ?

Re: Melting ice caps.

It has to be a tiny portion of the total mass of the planet (some 5.972E24 kilograms) so I would doubt it would have any effect on the axis angle.
It would be interesting if it did though.

Well I guess in line with the Mayan prediction for Dec 23rd 2012, we'll know soon enough  Undecided

Re: Melting ice caps.

This reminded me of a fun thing.  Imagine if every person on the planet were to gather in one place and at exactly the same time, jump.  6-7 billion people jumping at the same time, what sort of effect would that have on the planet?

People get this totally wrong.
Ice on the Arctic Ocean is floating, so when it melts there is no change in the balance of anything AT ALL.
Now ice on land well above sea level, e.g. Greenland, is a somewhat different matter.

Actually thats kinda wrong. Water when freezing expands. When it melts logic would follow that it will contract so in theory the water level should very slightly drop.

Operation Iceberg ( Tuesday) on BBC TV was  interesting, more than I thought it would be.
Second episode tonight.

Nope Sprite, although the volume has increased the density has decreased, so the ammount displaced is the same as what it was when liquid.

Re: Melting ice caps.

I stand corrected! I had wondered about that as I saw a time lapse video of ice cubes melting in a glass of water years ago but forgot about the density part of it when posting.
