Using ICESat measurements, scientists found that overall Arctic sea ice thinned about 0.17 meters (7 inches) a year, for a total of 0.68 meters (2.2 feet) over four winters. The total area covered by the thicker, older "multi-year" ice that has survived one or more summers shrank by 42 percent
According to the study (NRC, 2006): • There is a high level of confidence that the global average temperature during the last few decades was warmer than any comparable period during the last 400 years. • Present evidence suggests that temperatures at many, but not all, individual locations were higher during the past 25 years than any period of comparable length since A.D. 900.
However, uncertainties associated with this statement increase substantially backward in time. • Very little confidence can be assigned to estimates of hemisphere average or global average temperature prior to A.D. 900 due to limited data coverage and challenges in analyzing older data.

Yes, it's called nature.
[Most of Earths history has been without a polar ice cap.
So, if most of Earths history has been without one, then why are WE as humans attempting to change our climate to keep one? Just so our coastal cities aren't put in danger? Trillions of dollars at stake you know.
Isn't that the exact opposite of the global warming wackos want? The planet is going back to what it would do with or without us.
I'm perfectly fine without a Polar Ice Cap, and so has our planet and life. In a few thousand years everyone will be talking about Global Cooling and how to prevent that very same ice cap from re-forming. Unless of course by then they have the basic understanding that the energy output of the Sun is not a constant, and neither is our distance.
The Earth a dynamic system.
[It's pretty laughable at best, until you realize they want to take more of your money in the name of global warming when it's really nature -- not man, that causes it.
It really is the greatest scam of history.
