Allan Astrup Jensen: Time Trend of Arctic Sea Ice Extent

SCC Volume 3.4

The NSIDC website, IPCC’s reports and some scientific papers have announced that the Arctic Sea ice extent, when it is lowest in September month, in recent years has declined dramatically, and in few decades the sea ice is supposed to disappear completely in the summer.

In that way new and shorter ships routes will open up north of the continents.
The facts are, that the Arctic Sea ice extent measured by satellites since 1978 expresses annual variations and it has declined considerably from 1997 to 2007. However, before that time period, from 1978 to 1996, the downward trend was minimal, and in the last 17 years from 2007 to 2023 the downward trend has also been about zero. Therefore, there is no indication that we should expect the Arctic Sea summer ice to disappear completely, as predicted, in one or two decades…..
