Some think it is decreasing but even that hasn't been proven. Let's face it ever spring Snow melts, this may surprise you if you are a city boy used to seeing Snow trucked away by I can tell Snow does melt and so does ice.
Now you may try to say it is the warming air that is melting the Snow. To which I say yes the air warms up every spring and melts the Snow. Some years are just more agressive than others.
Besides all of that you have long term cycles in the Pacific Ocean that can have a massive impact on ice at the north pole. As you may suspect water will have a greater impact on that ice cap than air.
Another thing to realize is this isn't the first time in history, we are talking recent history here that there has been a melt off of ice in the North. So what evidence is there that this melt off is special in some way. The short and sweet is there is none, all we got is several sets of scientist saying the ice has melted. It may have were they measured but at least one group has admitted that their instruments had calibration errors that invalidated their original findings. Of course this has been surpressed by the lunatic fringe.
In any event let's say the ice is actually thinner than expected, the problem is how do you link that to manmade global warming. That is how do we factor in manmade causes along with everything else that is happening. That is known long term environmental cycles, volcanic activity, output from the sun and other factors. The reality is man is a puny factor when you consider these other factors.
In any event show me the mechanism where by mans activities have caused the ice to melt. It simply isn't good enough to say so, nor has there been a model put forth that clearly links CO2 to a planetary temperature increase. Yes I know there are lots of computer models that the developers think they have nailed down but absolutely none of them have been proven correct.
Sadly you will like many here, dismiss my point of view as a nut case from the extreme right. That is not the case at all, I'm not however gullible nor easily persuaded to adopt ideas that don't stack up. Nor do I have time for scientist that come off as crack pots. So if you don't like my point of view talk to an astronomer or a geologist who each have differing points of view on the subject.
You will eventually see that very well educated people don't always agree on this subject. In the case of Astronomers and Geologist they take a much longer view of events on and off the planet. The fact is there are a huge number of factors involved in the earths temperature, until there is a way to combine all of those into a computation we will not know what is going on.
The one really obvious problem with the global warming predictions is that they make the assumption that the sun has no impact on temperatures. This summer should make it glaringly obvious that a quite sun cools off the earth real fast, yet the suns impact is a constant with repect to the global warming crowd. Frankly it would be sad to here these people in normal scientific discourse but unfortunately they are very skilled at manipulating public opinion via thinly vieled threats to ones future. Sadly the science part of the debate died a long time ago, now it is all about threats and scare techniques to move a political agenda.
