The record-breaking warming of the oceans is not visible in the Arctic

The most important newspaper of Finland, Helsingin Sanomat, took a stance in its editorial on Minister Kaj Mykkänen's (National Coalition Party) comment, according to which the key climate action in Finland is to plug factory chimneys. A couple of days ago, I also commented on this matter in Finnish, pointing out that human progress is based on science and technology – and reminding that insect infestations threaten forest carbon sinks in a warming climate.

Climate change has also been commented on by Petteri Taalas, Secretory General of the World Meteorological Organization, who says that the problems predicted by climate researchers in the Greek archipelago back in the 1980s are now becoming a reality. This led me to once again look at the development of northern sea ice extent. One might imagine it melting rapidly right now, given that the surface water of the North Atlantic is warmer than ever in recorded history.

My surprise was significant when I observed that the extent of northern sea ice on July 24th, relative to this time of year, was the tenth smallest in the statistics. The years 2007, 2011, 2012, 2013, 2016, 2017, 2019, 2020, and 2021 were surpassed.

However, it is true that the last time I wrote about the subject in English, sea ice was 12th smallest, so its relative extent compared to recent years has decreased. On the other hand, compared to the record year 2012, the extent of northern sea ice is over five percent larger – when I wrote about it in Finnish, the difference was just under five percent – so in that respect, it has expanded rather than contracted. This could, of course, be due to the exceptional anomaly of the year 2012.

So, we'll see if the warm water from the North Atlantic finally flows to the Arctic region and begins to melt the northern sea ice. And thus, would bring closer the day – which climate researchers say is inevitably ahead – when the Arctic ice completely disappears.
