Of course I knew that there were articles like that on the subject that you mentioned but is that really what they say? You shouldn't get yourself so worked up over such things. Nearly all of them say that arctic ice COULD be seasonal gone or that it MAY be seasonally gone or that the NW passage could be open by some year in the future depending on when the article was written. Do you know the meaning of the words that I capitalized? Sure you do. If you know the meaning of those words, then you know that those conditions may or may not come to pass as well. In that really neat link you provided, the first article mentions that the arctic could be navigable some day. Well, seasonally the arctic is navigable now, so there's one that has come to pass. From what I've read, in the summers now there is less sea ice in the arctic than there was, for example, when I was a kid. Talking about climate change is fun, don't you think?
