    Sea Ice Ends Year at Same Level as 1979

    Sea Ice Ends Year at Same Level as 1979

    DailyTech - Sea Ice Ends Year at Same Level as 1979


    Rapid growth spurt leaves amount of ice at levels seen 29 years ago.

    Thanks to a rapid rebound in recent months, global sea ice levels now equal those seen 29 years ago, when the year 1979 also drew to a close.

    Ice levels had been tracking lower throughout much of 2008, but rapidly recovered in the last quarter. In fact, the rate of increase from September onward is the fastest rate of change on record, either upwards or downwards.


    With all the chicken little threads about melting ice, I found this article rather intriguing... If you read the article, it even mentions how some thought the north pole would completely melt by 2008. I believe this has not occurred and levels seem to ebb and flow.

    All due to Global Warming.

    I do note a lack of responses in this thread.

    But, but, it can't be true. Al Gore said we'd all be sailing across the north pole by now in tourist boats.

    The study that I assume you are referring to with the 'chicken little' comment was studying the melting of land ice, which impacts sea levels rather than sea ice, which does not. Also, the study that put forth the possibility of the melting of ice at the north poll was speaking of a temporary event during the summer, and only gave it about a 50% probability.

    What say you regarding this phenomenal increase in sea ice? Is the north pole NOT sea ice?

    Sea ice is very volatile, but pretty steady over time. Here is the graph from the article



    There is an uptick at the end of 2008, but the article gets a bit sensationalist about it as it's no bigger than a few dozen other spikes in the graph, including three in 2007 alone. From the graph the level indeed looks the same as 1979...and 1980....and 1981....and 1982....you get the picture.

    Yes it is. In a year the amount of ice cover at the North Poll varies greatly. There was a possibility during the summer that the ice cover would recede completely at the spot of the north poll (there would still have been ice around it, but not at the actual poll), but this would not have been permanent had it occurred. It just would have been a moment at one of the yearly troughs in that graph. I'm afraid the media misrepresented the situation quite a bit while it was happening.

    Looking at your graph, it seems there is no movement on the sea ice, just a steady ebb and flow. Wouldn't global warming have shown a different effect?

    No idea. I don't know how sea ice fits into the big picture like how it forms or what affects it. If I had to venture a guess (and it is a guess) I'd look at the effects of great swaths of land ice breaking free, as we see every few months when some Antarctic ice shelf breaks off. If I had to venture another guess I'd say that sea ice, which tends to be submerged for the most part, is less susceptible to atmospheric changes than land ice, which is more exposed. Neither of those are based on anything but common sense, though.

    Global warming is seen much better in longer intervals of time, rather than just 30-40 years.
