Over the past few days, a plethora of articles have been published saying that Arctic ice is melting at a faster rate than last year, which was a recent historical record, and the North Pole will soon be ice free. The graphic below and link to this thread show the opposite:
Compare (Arctic) Daily Sea Ice
Associated web page:
As for the North Pole being ice free, there are openings in the sea ice that don't mean the entire surrounding area is free of ice:
The Top of the World: Is the North Pole Turning to Water?
Hmmm...
missed the spelling error:
Aarctic=Arctic
By the way, notice the ice still on Hudson Bay this year. It wasn't there last year. Great visual.
Global warming PING!!
Thanks. A visual view of the ice sheet’s extent beats graphs and words. Be sure to play with the interactive and view how last year’s ice diminished through the summer and into early fall.
BTW, light purple is 80% sea ice concentration; dark purple increases toward 100% ice coverage.
RE: Arctic Sea Ice News and Analysis
From that web site:
“Although ice extent is slightly greater than this time last year, the average decline rate through the month of May was 8,000 square kilometers per day (3,000 square miles per day) faster than last May. Ice extent as the month closed approached last May’s value.”
I don’t know how they figure that, nor do I know how they confidently extrapolate that into a complete melt projection. The pictures in this thread seem to indicate, regardless of this analysis claims, that sea ice is still greater this year at the end of June.
Go figure!
It would be nice if legends accompanied the various sea ice graphics that get posted on FR. It’s hard to make heads or tails if the colors are not explained.
It might open up near the end of August for a few weeks. Park your ship off Baffin Island now, wait six weeks and take your chances.
Sorry if you can not see the legend; it is at the upper left of the graphic:
For Firefox, click "View Image" then "+" and scroll to the upper left where the color code is explained.
For IE-6, I don't see any easy way to enlarge the picture (the "show picture" tab is grayed out) though you might try saving the picture and viewing on Windows Picture Viewer.
Or you might go to the UI-UC website and see if you can work with their images.
It looks like the Navy doesn’t like external links. Here is the page with various other pictures of Subs at the North Pole including the USS Skate.

JDIA,
Missing your picture...
Got it! Thanks
Just a side note,,,,
If I recall correctly, about a week ago was a posting that there were some new and gigantic volcanos forming up on the undersea ridge between the top of Greenland and Russia.........
You dont suppose that perhaps thousands of cubic miles of molten lava could increase the polar sea temp just a little bit, could it?
I'm sure it does, but of course the MSM doesn't say much about that because it's unlikely any change could be easily quantified and they don't want anything to dilute their gloomy message. Of course man-made global warming can't be quantified either, except by their garbage-in garbage-out computer models, but that doesn't stop them from saying we humans are to blame.
I love the interactive photos on this site. You can compare any two dates back to 1979.
BTW, they just updated the site with today’s photograph (June 30, 2008).
They are probably doing it with some kind of satellite algorithm, but there are no details readily available.
This winter there was a significant freeze/formation of first-year ice; this ice will be the fastest to melt, so if there was more ice cover at the "height of winter" than last year, and temperatures following roughly the same summer warming trend, then there is a probably a larger area of ice amenable to faster melting now than at a comparable time last year.
Thanks, is there a link to a site where we can get these type of pictures on a daily basis?
The satellite picture above is from the MODIS satellites which provide near real-time visible images - maybe an hour or two old (I like visible because it is a real picture - it has not been massaged by a global warming programmer at the NSIDC like the other radar/software-generated images.)
The downside is that clouds can get in the way and it is not taking pictures of Antarctica right now (since it is in 24 hours of darkness) - nighttime sections of pictures are not shown.
The MODIS sats require a little getting use to. They take a picture every 5 to 10 minutes or so in their polar orbits - you have to click through PREV and NEXT to get the location and orientation you want. Different resolutions are available down to 250M and various filters let you distinguish clouds from ice. Start with 4km resolution till you get used to it.

Edit your Favourite link as the below since this link will automatically take you back to the same day each time unless you take the date out.

Excellent information, thanks much. I have made it one of my favourites!
Yes, that is one of the stories I read, another one mentioned huge volcanos forming on the sea floor. It was previously thought to be too deep—therefore too much pressure—for volcanic eruptions. Apparently one of the biggies had strewn rubble out 10km around it, as I recall. There appears to be a lot of undersea activity that we have very little knowledge of.

And we need it to warm up because....
Um, aren’t there billions of barrels under the Gull Island holes (way up there) which were capped a few decades ago without pumping them out?
See the second link just above .... for a discussion on that ...myth...
Thank you, that helps a great deal!
