The reason is because Google only has aerial images over the land masses.
Antartica is a land mass and so you see an aerial image with lots of ice and snow. There are no images of the oceans - you just see a profile of the sea floor (which is why you can see the mid-ocean ridges). As the ice cap at the norh pole is just sitting on the ocean, theres no aerial image.
The ice cap is still there, honest ;-)
This is possible but not with the image you have as it stands.
Have a look at this post from the GE Community for more about this: http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/696446
Here is an image overlay (altough not a very detailed one) of the North Pole: http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/571358
If you save that North Pole image overlay onto your hard drive and change the extension to .zip you can open the archive with WinZip (for example). Inside, you'll find a GIF image. Open that and you'll see how you would have to edit and distort your image to fit the projection required in GE.
This is similar concept to Mercator Projection: http://en.wikipedia.org/wiki/Mercator_projection
KML Feature - National Snow and Ice Data Center (NSIDC)
The National Snow and Ice Data Center (NSIDC)
based at the University of Colorado, Boulder uses a variety of
scientific data sources to provide
research results relating to climate change and other environmental
factors where snow and ice are concerned. One of the methods of sharing
these results is by using Google Earth to create a series of high quality
KML files, meaning their data is no longer hidden away accessible to few. A recent NSIDC addition to our Google Earth Outreach Showcase provides an assessment of the relationship between melting glaciers and climate change. "Explore a KML providing a rich geospatial
presentation illustrating the changes in glaciers over the years.
In his speech, Mr Gore told the conference: â€śThese figures are fresh. Some of the models suggest to Dr [Wieslav] Maslowski that there is a 75 per cent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.â€ť
However, the climatologist whose work Mr Gore was relying upon dropped the former Vice-President in the water with an icy blast.
â€śItâ€™s unclear to me how this figure was arrived at,â€ť Dr Maslowski said. â€śI would never try to estimate likelihood at anything as exact as this.â€ť
Mr Goreâ€™s office later admitted that the 75 per cent figure was one used by Dr Maslowksi as a â€śballpark figureâ€ť several years ago in a conversation with Mr Gore.
