What happens if the polar ice caps melt?
Based on the results from the
experiment, it is clear that floating ice does not add extra volume to a body
of water that it melts in. Most of the
ice is under the water already, and the density of ice is less than the density
of water. In other words, when ice
melts, it actually takes up less space.
Therefore, I am fairly certain that the melting of any ice currently in
the oceans will have little to no effect on sea level. On the other hand, the ice currently on land does
not contribute to the existing volume of water in the oceans. Therefore, if much of this ice were to melt
(like the Antarctic ice cap), water previously not present in the oceans would make
its way there. This would result in
massive flooding along coastal areas, which would in turn cause many other
disastrous side effects, mainly the spread of illness. So to sum it all up, if the polar ice caps
melt, flooding will likely occur due to the water running off the land into the
sea (Antarctica or Greenland) rather than due to the already existing icebergs
(which make up most of the northern ice cap).
