I was being sarcastic using the word that way.  I'm not being snarky now in saying so, either, just speaking plainly.   I know that the absence of the ice is seen as future economic opportunities for a lot of people.  

However, if you look at the subject of the arctic ice through the lens of science, which is my preferred perspective, discussing a blue ocean event cannot be interpreted in a positive light under any circumstances.   The loss of the ice might be a positive money-making venture for a few seasons for a relatively miniscule number of people, but it is also likely to lead to extremely rapid warming in a very short period of time soon afterward, as in within a decade.   Humans have never been on a planet without an arctic ice cap.   We don't know what will happen, but we know it likely won't be good, if the Permian extinction event is any indicator.
