2018 10.422 million km2
The important point - which might even be considered a scoop in the light of recent media information about the climatic change - is that six days ago the extent of the arctic ice was the largest (of date) during the last ten years (right now it is the second largest after year 2014).
The table above tells us - at least - that the melting rate of the arctic ice is not especially rapid. It should, however, be noted that the extent was biggest in early dates of the statistics: 11.897 million km2 in both years 1983 and 1992, and the extent was 10,700 million km2 in year 2008 when it was for the last time larger than this year.
It remains to be seen if Jari Haapala, Research Professor of the Finnish Meteorological Institute, was right couple of years ago, when he predicted that it will take only few years before we can sail to arctic pole through an open sea and that the arctic sea ice will completely melt away during the 2030´s or 2040´s. That is, during the next 12 or 22 years.
Therefore it is also good to take a look on the extent of the arctic sea ice, when it was smallest in this year: 4.594 million km2. Also this figure needs a comparison table, before it can be interpreted.
2018 4.594 million km2
As can be seen from the table, this year is in position six in this statistics. The extent of the arctic sea ice was smallest in year 2012 and largest in the first year of the table. Therefore we can conclude that Research Professor Haapala´s view about the ongoing rapid melting of the arctic sea ice is not supported by this table. Or more exactly: this table does not show any trend.
Despite the two tables above, I have no idea whether the arctic sea ice is melting or not in a long run. And certainly I do not want to guess whether we are in the middle of climate warming caused by human actions.
Instead, I am willing to bring this piece of information about the extend of the arctic sea ice to public discussion, because I suspect that it will not be reported by main media and will therefore not reach the ordinary people in Finland and elsewhere.
I wrote this article in Finnish six days ago, but there has been no news about the extent of the arctic sea ice. The reasons may be imagined, but I am not willing to open my own thoughts. Instead, I want to point out that the instructions of Finnish journalists say the following. "A journalist has a responsibility towards her readers, listeners and watchers: they do have a right to know, what is happening in the society."
The original thought in Finnish:
Skuuppi, joka jäänee mediapimentoon
