One of my favorite sites is:
I personally think sea ice could be mostly gone within the next ten years. When I started watching this several years ago I thought I was been brave to predict as early as fifteen years. I had to wait for confirmation of the current speed of the melt. It is coming in spades.
I reasoned that you do not lose sixty percent of ice thickness over 40 years on a linear basis. Yet we only had two points of reference consisting of the 1958 international geophysical year when an ice thickness survey was conduced by submarine. This was repeated again at the turn of the century. The difference of sixty percent was unanticipated.
The majority was likely lost in the last third of those 40 years or over a period of about fifteen years. That meant that the remaining forty percent should largely disappear in the succeeding fifteen years. And at some point toward the end it should flush out very quickly like a spring breakup since most of the long term sea ice will have been eliminated.
In the mean time it is fun to watch. Note that grey areas in the strong white areas likely reflect standing water at the least and semi open water in the main. I think that the grey areas have been growing larger and more widespread each year also. We still have a month left in this season.
Won't everyone be surprised?
I am looking forward to a cruise through the sea ice to the North Pole and Northern Greenland and
I also would like to note that the polar seas will be covered every winter with seasonal sea ice that will break up and almost disappear over a fairly long summer season. It will still be as inhospitable as ever.
And we seriously need a cold snap up there.
