Jasper, you're not clear in what you think the 'circular' means to you.

Look at the following. I've studied the University of Illinois's cryrospere photos quite a bit. They do NOT prove that there is a hole at the pole's whatsoever. What I think they DO help prove, is a Cover-Up of what really is at the poles. You don't see the circular image overlay cover up so much in the current years' pictures. But here is one going back to 1983, and I've place the yellow circle around the circular changed area to highlight what is there. They (NASA) has placed a large overlay/smear, roughly several hundred of miles across, over their infrared 'red' portion, directly at 90N.
Look too at the second one where I placed 1984 side by side with 1985. What are they hiding ? ? ?
