I threw in the link to a map and comparison map.  Everything is in place for the 2007 levels to be met although wind is supposed to have a lot to do with it all.<\/o:p><\/span><\/div>\n
<\/div>\n
The reality is that we have been and continuing to lose roughly the same amount of ice each year.  Because so much has now been destroyed the impact of each year is rapidly accelerating.<\/o:p><\/span><\/div>\n
<\/div>\n
I predicted now almost three years ago that the loss rate strongly supported a general wipe out by 2012.  I even made a bit of noise about it.  A couple of months later, someone over at NASA came out and said the same thing.  I suspected that they already knew as much and did not want to get caught out looking like idiots in four years.<\/o:p><\/span><\/div>\n
<\/div>\n
I actually predicted the present deteriation long before it became apparent that 2007 was going to be decisive year in ice loss.<\/o:p><\/span><\/div>\n
<\/div>\n
This story informs us just now rotten the ice presently is and just how little this winter\u2019s weather affected the <\/span>Arctic<\/span><\/st1:place>.<\/o:p><\/span><\/div>\n
<\/div>\n
My only surprise is over how few among the media or anyone else even understands what is happening.  Recall every scientist was calling for a loss of ice safely in the distant future and generally well outside the likely time lines of their career.   It was apparent that no one appreciated the trend lines except in the most simplistic terms conforming to linear assumptions in a clearly non linear process.<\/o:p><\/span><\/div>\n
<\/div>\n
At this point their worst expectations are turning out to be ridiculously conservative and obviously misleading.  The <\/span>Arctic<\/span><\/st1:place> is opening up to global shipping and will now be open for perhaps four hundred years.<\/o:p><\/span><\/div>\n
<\/div>\n
I am been aggressive on this and my reasons are sound.  The warming that is hitting into the <\/span>Arctic<\/span><\/st1:place> is ocean based and is part of a millennial cycle.  It will actually get much warmer before this is all done. <\/span><\/o:p><\/div>\n

Arctic sea ice heading for new record low<\/o:p><\/span><\/i><\/b><\/div>\n

Coverage at 2007 level now, and declining faster, making ice-free northern summers possible soon<\/o:p><\/span><\/i><\/div>\n

The Canadian Press<\/span><\/i>Published on Thursday, May. 20, 2010<\/span><\/i><\/o:p><\/span><\/i><\/div>\n
<\/div>\n
Arctic sea ice is on track to recede to a record low this year, suggesting that northern waters free of summer ice are coming faster than anyone thought.<\/o:p><\/span><\/i><\/div>\n
<\/div>\n
The latest satellite information shows ice coverage is equal to what it was in 2007, the lowest year on record, and is declining faster than it did that year.<\/o:p><\/span><\/i><\/div>\n
\u201cCould we break another record this year? I think it’s quite possible,\u201d said Mark Serreze of the National Snow and Ice Data Center in Boulder<\/st1:city>, Colo.<\/st1:place><\/st1:state><\/o:p><\/span><\/i><\/div>\n
\u201cWe are going to lose the summer sea-ice cover. We can’t go back.\u201d<\/o:p><\/span><\/i><\/div>\n
In April, the centre published data showing that sea ice had almost recovered to the 20-year average. That ignited a flurry of interest on climate change<\/span><\/a> skeptic blogs.<\/o:p><\/span><\/i><\/div>\n
<\/div>\n
But much of that ice was thin and new. The warmest April on record in the Arctic<\/st1:place> made short work of it.<\/o:p><\/span><\/i><\/div>\n
Ice cover has already fallen back to where it was in 2007 at this time of year and is disappearing at a faster pace than it did then. Dr. Serreze said winds, cloud cover or other weather<\/span><\/a> conditions could slow the melt, but he points out that the decline is likely to speed up even more in June and July.<\/o:p><\/span><\/i><\/div>\n
<\/div>\n
\u201cWill [thawing] this year be particularly fast?\u201d he asked. \u201cWe don’t know. We really don’t know.\u201d<\/o:p><\/span><\/i><\/div>\n
One of Canada<\/st1:place><\/st1:country-region>‘s top sea-ice experts suggests things might even be worse than Dr. Serreze thinks. His data could be underestimating the collapse of summer ice cover, said David Barber of the University<\/st1:placetype> of Manitoba<\/st1:placename><\/st1:place>. Researchers can’t learn anything from satellite data about the state or thickness of the ice.<\/o:p><\/span><\/i><\/div>\n
\u201cWhat we think is thick multiyear ice late in the summer is in fact not,\u201d he said. \u201cIt’s heavily decayed first-year ice. When that stuff starts to reform in the fall, we think it’s multiyear ice, but it’s not.\u201d<\/o:p><\/span><\/i><\/div>\n
Arctic explorers and scientific expeditions are finding more open water and untrustworthy ice ever, Prof. Barber said.<\/o:p><\/span><\/i><\/div>\n
He pointed out the Arctic<\/st1:place> continued to lose multiyear ice even in 2008 and 2009, when total ice coverage rebounded somewhat.<\/o:p><\/span><\/i><\/div>\n
True multiyear ice \u2013 the thick, hard stuff that stops ships \u2013 now comprises about 18 per cent of the Arctic ice pack. In 1981, when Prof. Barber first went north, that figure was 90 per cent.<\/o:p><\/span><\/i><\/div>\n
\u201cThis is all just part of a trajectory moving toward a seasonally ice-free Arctic<\/st1:place>,\u201d he said. \u201cThat’s happening more quickly than we thought it would happen.\u201d<\/o:p><\/span><\/i><\/div>\n
Once northern waters are clear in the summer, there will be little difference between navigating the Northwest Passage and the Gulf of St. Lawrence<\/st1:place>, he suggested.<\/o:p><\/span><\/i><\/div>\n
He recounts sailing through degraded ice in an icebreaker. The ship’s top speed in open water was 13.7 knots. Its speed through the decayed ice was 13 knots.<\/o:p><\/span><\/i><\/div>\n
