GIS Development has a small article about Satellite data showing a grim picture of Arctic ice melting. From the article: Scientists at NASA and the National Snow and Ice Data Center, which have monitored the ice via satellites since 1978, reported that the total Arctic ice in 2005 will cover the smallest area since they started measuring.

Slashdot discuss a Yahoo! News article about ESA's Envisat and EOS Aqua "showed Arctic ice cover had disappeared so much last month that a ship could sail unhindered from Europe's most northerly outpost to the North Pole itself". From the article: "Regular satellite monitoring over the last 25 years shows that the northern polar ice cover has shrunk and thinned as global temperatures have risen.
But this year's images are unprecedented, and fierce storms that fragmented and scattered already thin pack ice may be to blame, the scientists believe." See last year story on the same topic. Update: 09/21 17:29 GMT by S :La Cartoteca links to a ESA article with screenshots.
Minimum Sea Ice Comparison
[+]
st_0x0ef writes "NASA’s Goddard Space Flight Center has produced some animations showing the ice loss in the Arctic Sea. The change over the last 30 years is pretty impressive. The 2007 Arctic summer sea ice reached the lowest extent of perennial ice cover on record — nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry."

I don't see a scale
what difference is it going to make?
(Score:2, Interesting)People(well most of them anyway) are just going to keep doing what they did before. Pollution levels will still remain the same and will probably increase.
Everyone is going to keep driving their cars that emits a lot of pollution. Everyone will keep using electronic devices that contributes to pollution. In fact, using almost any kind of electronic device contributes directly or indirectly to pollution. That doesn't mean we will stop using these devices anyway.
It reminds me of a quote that i read before regarding security professionals. "We security professionals are like cardiologists. People will eat unhealty food and will clog up their arteries. When things become extremely bad, they will come go to them and ask for a 'magic pill' that will solve everything."
Perhaps the quote can be applied in this case as well, to environmentalists. The only thing that I can think of to slow down any adverse effects greatly is to look for a much cleaner energy source. But we will never have that. We are too busy fighting with ourselves.
