This might help answer your question.
The north pole is ice that floats on the surface of the sea and Google Earth shows that as blue or part of the ocean. Antarctica is actually a land
mass covered in ice and is shown as is.
If you want to see the ice at the northern pole you need the sie.kml. Download it and open it with the Google Earth program.
This link should get you what you need.

It's partway down the page and it's called the "Sea Ice File".
This is what I see with it installed:
New Snow and Ice Data for Google Earth
Sea Ice Extent from NSIDC in Google EarthThe National Snow and Ice Data Center (NSIDC) is part of the University of Colorado and affiliated with NOAA.
Last April the NSIDC released a Google Earth collection showing examples of glacier melting by showing the locations in GE along with photographic
pairs from years ago compared to today. With the increased focus on ice and the polar regions of Earth (since the start of the International Polar
Year), the NSIDC has released some new GE content. They have a page dedicated to GE content on snow and ice, and a "Featured Data" section. One of
the featured content collections shows the sea ice growing and shrinking over time for both poles.
Download the Sea Ice file. You must have Google Earth installed, and you will immediately see an "animation" showing the ice extent around
the poles during the month of September from 1979 through 2006.
Here's another link with more information for you that might be helpful:
