As an "unscientific" observer, operating in complete ignorance of all of the scientific research that has been done on this matter, you should just assume right off the bat that everything that "occurs" to your uninformed little mind (or that is spooned into it by the fossil fuel industry propagandists) has already been studied and analyzed by the highly educated and experienced scientists who have studied this subject full time for decades.Just a unscientific observation, did it ever occur to our pro AGW advocates that if the ice does not melt or retreat some of the time, and if it otherwise continues to get thicker and more expansive all of the time, that we would eventually all be up to our hoo has in ice over both the northern and southern hemispheres?
Over the last two and a half millions years, due to natural factors, polar ice has repeatedly (about 7 times) expanded enormously to cover most of North America during periods that are called "glaciations", and it has repeatedly shrunk back to something like its present extent during periods that are called "inter-glacials". The Earth is currently in one of those inter-glacial periods that has now lasted for about the last ten thousand years. The natural cycle of things caused by orbital dynamics would see the Earth in a gradually cooling phase now, leading up to another period of intense glaciation tens of thousands of years from now. What has happened instead is that mankind's activities, primarily the burning of fossil fuels and deforestation, have reversed the natural trend and substituted an un-natural abrupt warming trend that is pushing the Earth's climate systems towards temperature extremes not seen in millions of years.
Your knowledge of both this issue and science in general seems miniscule and very incomplete.We haven't been tracking arctic ice for all that long because we have only had the capability to do so for 34 years.
You base your conclusions on your own ignorance, not reality. We don't need to have billions of years of data to understand what is happening. Scientists actually have hundreds of thousands of years of good proxie data on past climate conditions that fits together in a pretty coherent picture of the forces and factors at play in past climate changes. The experts are not as ignorant about this as your own ignorance projects them to be. Scientists have analyzed the various things involved in all of these past climate shifts and those things are not happening now. The only thing consistent with the laws of physics that can explain the current abrupt warming is the rapid 40% (and still rising fast) increase in atmospheric CO2 levels that human activities has created.Thirty four years is but a teensy tick in the history of the arctic ice, so we honestly don't know how many times the arctic ice has significantly retreated and advanced over open water in the billions of years it has existed.
Reconstructed changes in Arctic sea ice over the past 1,450 years

Abstract (excerpts)
Arctic sea ice extent is now more than two million square kilometres less than it was in the late twentieth century, with important consequences for the climate, the ocean and traditional lifestyles in the Arctic(1, 2). Although observations show a more or less continuous decline for the past four or five decades(3, 4), there are few long-term records with which to assess natural sea ice variability. Until now, the question of whether or not current trends are potentially anomalous(5) has therefore remained unanswerable. Here we use a network of high-resolution terrestrial proxies from the circum-Arctic region to reconstruct past extents of summer sea ice, and show thatalthough extensive uncertainties remain, especially before the sixteenth centuryboth the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years. These results reinforce the assertion that sea ice is an active component of Arctic climate variability and that the recent decrease in summer Arctic sea ice is consistent with anthropogenically forced warming.
And here you reveal that because you are ignorant of (and probably uninterested in) the actual scientific facts that indicate that our world is facing a severe crisis, you really base your objections to the scientific conclusions about the Arctic ice loss on your political fears, whipped up by some clever propaganda, that you might be faced with some (very necessary) changes to our energy infrastructure and possibly your current way of doing things. Or in other words, you've been fooled into being a stooge for the continued profits of the fossil fuel industry.Certainly 34 years is not sufficient to merit massive mandatory social changes.
Just a suggestion, little dude - try learning more about this subject from good sources of accurate scientific information instead of the rightwingnut media echo chamber and astro-turfed blogs before you make a fool of yourself on here again.
Well BIG DUDE, since you seem to think I have not studied the subject sufficiently, and you have no clue what I have or have not studied, but you have nothing more to contradict my take on it other than a string of juvenile personal insults, I'll just thank you for your opinion (of me) and say this before moving on:
