Another month has gone by and it is time to consider where the planet lies in relation to the health or otherwise of Arctic Sea Ice. It has been a shaky year this year but not at all one of concern for the Northern ocean sea ice conditions. As the months have turned over this year, each representing the half way point for the current, fifth decade of satellite assisted records at the time of their passing beneath the bridge of time, it has been becoming clearer – although no conclusively so until the next full decade average ice cover line has been drawn as the decade closes its door, becoming, at that point, history – that a change perhaps begun during the previous decade (as some noted), which marks a veritable complete stoppage to any further advancement in sea ice disappearance, this century and this very decade. That was something not at all expected more than some 15-20 months ago. But something which could possibly have been predicted with a little knowledge and foresight from historic records of such earlier similar periods of ice changes going back some 200 million years or so to ther Eemian and Holsteinian Inter-Glacial periods.
Enough said. We are, or are increasingly likely to be, witnessing something of the sort right now. Exciting stuff, no?
Well, whether you agree or not, the latest data shows that even after a poor start to the year, thanks to a lethargic performance from the latter months of 2024, the year has recovered to demonstrate only four out of ten months so far showing a slight negative average amount of sea ice present at each month end than in the previous decade averages for the same parts of the year. Which means that six out of ten months so far have shown a positive gain of ice extent. And with the annual ice reformation period now in full swing, the final two months are likely to also show positive results. This is exceedingly good news which I am sure will bring only dismay to those who dream of upcoming climate calamity scenarios. How anyone can still beat that drum is a source of amazement to me.
Here is the latest NSIDC sea ice graph data which you can merrily interact with yourself…
And here is my update spreadsheet giving actual data figures. Current Arctic sea ice accumulation as at November 1, 2025 was recorded at 7.67 million Km2. Providing a five year average for the same month end in the current decade of 8.082 million Km2. And representing an average for the same part of the year, more than during the previous decade, by 95,000 Km2. Whereas there has been an average loss of over 1 million Km2 per decade over the previous two decades.
The Arctic ice cover may now be said, or perhaps just surmised at this point, to be returning its lost extent.
Is that not something that is both encouraging and heart-warming?
I don’t have much more time to spare on further comment, but look at the High and Low range data I added last month. See what you can make of that.
