When Social Media Stops Being Social

A Finnish political media, Verkkouutiset, had drawn attention to the fragmentation of political discussion on social media, resulting from the fact that many people follow only those whose opinions are close to their own. As a result, the term “social media” no longer really describes what it is; rather, it has become a platform for bubble formation or— as it used to be put— a like-minded circle jerk.

An excellent example of this is X, formerly Twitter, where discussion is almost unmoderated. However, there are several ways to shape one’s feed toward such a circle and eventually drift into a so-called rabbit hole, where a person is drawn ever deeper into one type of content.

As a result, the discussions one encounters on social media end up consisting almost entirely of messages representing a single worldview—one whose challenges remain unseen and perhaps even unrecognized.

* * *

It does not necessarily have to be this way, even though X—like, as far as I understand, nearly all social media platforms—uses an algorithm that serves users content based on their past behavior, “inferring” what they want to read.

In addition, everyone can choose whose posts they follow: for many, this means people whose opinions align with their own. But one could just as well follow the entire political spectrum on X, from the far left to the far right, from Nazis to anarchists.

Likewise, those who prefer their own circle can choose to make their posts visible only to selected audiences, excluding those whose views they do not wish to engage with. In doing so, however, they also forgo those people’s comments—and the challenge those comments might pose to their own thinking.

Even this has not been enough for everyone. Politically liberal and left-leaning groups created their own platform, Bluesky, a few years ago. Similarly, U.S. President Donald Trump launched his own platform, Truth Social.

Thus, what was once a platform known for lively political debate among adults has evolved into something where the very “social” nature of social forums can be questioned—something that fosters people raised in rabbit holes, whose worldview grows narrower day by day.

Blogs are also considered social media, including this one, Thoughts of the Professor, whose subtitle emphasizes the importance of freedom of speech.

As long-time readers know, my own writings are also politically opinionated and express my views on the issues at hand. But that does not mean I would not want to see opinions differing from my own in the discussions following each post—even ones that challenge me radically.

On the contrary, such views are highly welcome, as they offer alternative perspectives and provide material for both myself and my readers to develop our thinking and worldview.

That is why I hope criticism does not disappear from discussions related to Thoughts of the Professor – or its Finnish equivalent, Professorin ajatuksia – but instead evolves into high-quality, serious argumentation. After all, the blog’s original purpose is ultimately to be part of the broader political conversation in our society.

English or Finnish — That’s the Question

I have been considering returning this blog to its original purpose — to publish here only English translations of the most significant entries from my Finnish-language blog, edited when necessary to take into account an international readership.

There are three reasons behind this consideration. The first is lack of time, as maintaining two blogs takes up a large part of my free time. The second is that I suspect most readers of the English-language blog are in fact Finns, who can therefore also read my Finnish posts. Thus, posting less frequently in English might allow me to write Finnish entries more often than I do now.

For this reason, I ask you — my dear readers — to indicate on the discussion forum below, in a single word, whether you prefer to read the entries in Finnish or in English. Based on your comments, I will make my final decision about the future of this blog.

Observations on Arctic Sea Ice Challenge the Notion of Particularly Rapid Melting

I promised at the end of September, in my Finnish-language blog, to return to the topic of this year’s Arctic sea ice situation. At that time, it was already known—based on NSIDC’s daily measurements—that the annual minimum extent was the eleventh smallest in the history of the statistics. 

Then, at the beginning of October, the data on the average sea ice area for September was released. It appears at the endpoint of the curve below, under which only the points for the years 2007, 2016, 2019, and 2020 fall. Notably, this supports the view that the ice area has remained at the same level since 2007—that is, for 12 years already. The figure also clearly shows how, in September 2012, the ice area was distinctly smaller than in any other year.

This observation supports a recently published research report by Chinese scientists, according to which the phenomenon known as the North Atlantic Oscillation shifted from the lowest point of its negative phase in the early 2010s into a positive phase. As a result, the reduced heat and moisture, as well as the weakened downward longwave radiation, have led to a slowing of Arctic sea ice melting.

According to that study, however, this slowdown in melting would be only an intermediate stage, to be followed in the 2030s or 2040s by a rapid melting of northern sea ice—and subsequently, a series of environmental disasters around the world.

At this stage, of course, it is too early to take a position on that latter risk or its likelihood. Nevertheless, it can be stated that the slowdown in the melting of northern sea ice—at least for the time being—is a fact, one that seems at least partly to challenge the idea that the climate warming responsible for melting the ice is proceeding particularly rapidly in the Arctic region.

Stalled Melting of Northern Polar Ice Buys the West Time to Strengthen Arctic Capabilities

One of my greatest interests is the visibility of predicted climate change in the surface area of northern sea ice. Therefore, dear readers, allow me to return once again to this topic, as I have not reported on it for some time in this English-language blog.

According to the August statistics, the average surface area of northern sea ice last August was the seventh smallest in its recorded history, which began in 1979. This was because, over the past year, the ice cover was larger than in August of 2024, 2020, 2019, 2016, 2012, and 2007.

This fact fits well with the already established picture that northern sea ice shrank rapidly from the 1990s until 2007, after which its surface area has shown nothing more than random variation. This reality is also illustrated in the figure I have drawn below, where the X-axis shows the ice area in millions of square kilometers and the Y-axis shows the years.

The maximum extent of Arctic sea ice is usually reached in September, so later this month we will see whether the amount of navigable, ice-free water in the Arctic Ocean exceeds that of previous years. Based on the above statistics, this does not seem likely—but neither does it seem entirely impossible.

The size of northern sea ice naturally has its own scientific significance, particularly in the context of the threat of climate change. In addition, it carries major practical geopolitical importance, since during President Trump’s administration the United States has observed that Russia is clearly ahead of others in this respect.

In this sense, the slowdown of ice melting is very good news for the free Western world, as it gives the U.S. and other nations interested in northern maritime regions more time to build up their own capacities for operating in the Arctic. At the same time, this particularly benefits my home country of Finland, which is indisputably the world leader in building icebreakers and stands ready to offer its expertise to other nations as well.

Donald Trump’s Meeting With Vladimir Putin: The Advice He Needs

The presidents of the USA and Russia, Donald Trump and Vladimir Vladimirovich Putin, will meet on Friday in Alaska. Initially, it was said that the meeting would seek a ceasefire between Ukraine and Russia, but later the U.S. president’s office announced that it was merely about Trump’s desire to listen to Putin.

In reality, no one can know what will happen in Alaska. In Europe, there are fears that Trump might agree to support Putin in annexing part of Ukraine to Russia. That is, of course, one possibility, but not necessarily what will happen in Alaska—unless Trump is, in one way or another, in Putin’s pocket.

Assuming what I just wrote isn’t the case, it could well be that Trump realizes Putin is merely toying with him and is in fact only trying to weaken U.S. and other Western support for the Ukrainians—thus turning the battlefield situation to Russia’s advantage.

That is why it was unpleasant to learn that, right during the Alaska talks, Russia has achieved success east of the city of Dobropillia, where its forces have managed to advance along a strip over ten kilometers long but quite narrow. The risk is that Putin will succeed in convincing Trump that this breakthrough shows Ukrainian resistance is collapsing.

On the other hand, I think Russia’s narrow attack wedge will remind all Finns familiar with World War II of our own country’s successful motti battles, in which much larger Soviet units were destroyed by encircling them and cutting off their supply and relief. Unfortunately, it may be that Ukraine’s terrain is not as favorable for such a solution as Finland’s was.

After Trump and Putin agreed to meet, European leaders decided to influence the situation. This will take place later today in a telephone conference attended not only by representatives of Germany, France, Britain, Italy, and Poland, but also by the presidents of the European Commission and the European Council, Ukrainian President Volodymyr Zelenskyy, NATO Secretary General Mark Rutte, and Finnish President Alexander Stubb.

It remains to be seen whether this distinguished group will be able to influence Donald Trump, or whether he will simply listen politely and then, in discussions with Putin, do whatever he wants—in the worst case trying to sell Ukraine’s independence cheaply, and then leading the USA out of the community supporting Ukraine.

Even though I am quite certain that Trump will not read this blog, I cannot resist offering him one piece of advice. It goes like this: Vladimir Vladimirovich is a tough and ruthless dictator who, like others of his kind, listens only to someone similar. That is why Trump should not try to appease him, but instead show — without hesitation — his place as the leader of a state far weaker than the United States, and tell him to end the war here and now by promptly moving the “special operation’s” soldiers back behind Ukraine’s eastern border as it stood before 2014.

A Night at the Opera

At the London opera, one performer decided to stage a protest. It involved bringing a Palestinian flag onto the stage and holding it up for the audience to see.

This demonstration had no impact whatsoever on the situation of Palestinians in their homeland, nor did it bring peace between Jews and Arabs in Palestine. It also did not undo the reasons why the Israeli army — in its search for Hamas terrorists — has extensively destroyed buildings in Gaza.

Instead, the performer in question demonstrated a lack of respect for his employer, the art form he practices, and his audience. Nevertheless, it is quite possible that he found satisfaction in getting his moment in the spotlight — at the opera, in London, in Britain, and in the global media. And even in this blog.

Why Is Keir Starmer Commissioning an Inquiry Instead of Taking Action?

From the perspective here in Finland, it seems strange that the Prime Minister of the United Kingdom, Keir Starmer, has decided to commission an investigation into grooming gangs. This is because the existence of these gangs and their ethnic composition have been known in Finland for a long time already.

For example, I first wrote (in Finnish) about the subject back in 2017, that is, about eight years ago. At the time, I specifically stated that "the worst known case is probably the Rotherham rape ring, which operated in the UK for 16 years and was covered up by the authorities for years out of fear of being labeled racist."

Since then, I have continued to write about the topic. The following year, in 2018, I brought up a prostitution ring that had operated in Telford, England, for decades, "which may have had up to a thousand child victims, mostly from the native population."

In other words, the Asian grooming gangs in the UK—and the related issues with authorities—have been quite well known to us Finns for a long time. And we are also aware that Keir Starmer's administration tried to sweep the matter under the rug by blaming those who aimed to draw official attention to child rapists.

An example of this is my own English-language article, in which I stated: "this is why it is necessary to ask the people of Britain and the world—especially those who see far-right extremism and racism everywhere—why they consider violent protests acceptable in the case of George Floyd, but not in response to the child murders that have shocked the United Kingdom?"

So, if there is no ambiguity here in Finland about the existence or composition of the UK’s grooming gangs, then why on earth is Keir Starmer only now—in the summer of 2025—starting to take action... excuse me, ordering an investigation into the matter? Wouldn’t it be more appropriate to ensure that there is no room for such gangs in British society in the future?

A Couple of Exceptionally Important Matters

Good morning, dear readers. I have two extremely important things to share with you today.

The first important matter is an announcement. As you know, I have been writing a Finnish-language parallel blog, with content highly similar to this English-language one, although the posts have mostly been separate.

However, I have now decided that, moving forward, I will primarily write about topics related to Finland in Finnish and international topics in English. Of course, for good reason, I may still publish the same articles in both languages or, for example, write about domestic politics in English if I find it appropriate. However, as a general rule, I will follow the approach I just described.

* * *

My second important matter concerns the recently uncovered cheating by Norwegian ski jumpers. This is significant because Norway has long been both a true superpower in winter sports and a nation with an unblemished reputation. This was especially true after the Finnish cross-country team was caught using doping a couple of decades ago.

However, the recently exposed ski jumping suit fraud demonstrates that Norwegians are not inherently any cleaner than anyone else. It also reinforces my belief that their cross-country skiers used banned substances to enhance their performance in the early 2000s, just like many others did.

That being said, this does not mean that the Norwegian athletes did not deserve the flood of medals their male skiers claimed at the World Championships in Trondheim, which concluded yesterday. Nor does it diminish the achievements of Johannes Klæbo, the dominant skier of this era.

Of course, one can always speculate that the winner of the interval-start race in the classic technique would most likely have been Iivo Niskanen—had he been able to compete in the World Championships. Unfortunately for us Finns, medals at major competitions are awarded among those who participate, and in that field, Klæbo was superior to everyone else every single time. That was truly amazing!

Arctic sea ice contradicts with the climatic model predictions, but is that changing now?

One of the items I am deeply interested is the development of the climatic change in the Arctic area. For that purpose, I have made statistical analyses on the dependence between the atmospheric carbon dioxide concentration and the area of the arctic sea ice.

I published today my most recent analysis in Finnish, and decided also to write a short summary of that in English. I have also previously written a post on this topic into this blog, and recommend reading it in case you - my highly valued reader - are interested in details of this analysis. 

The idea of the analysis is simple: I am using September data (i.e. annual minimum) for arctic sea ice area of the National Snow & Ice Data Center (NSIDC) and carbon dioxide concentration measurements conducted in Mauna Loa. The latter ones are not available for year 2022 due to the eruption of the volcano, and therefore I had to use an estimate based on two previous measurements. The development of the concentration is given in the figure below, where the measured concentrations and estimated value are marked with blue and red color, respectively.

In the next figure I have marked the number of years after which a connection between the carbon dioxide concentration in the atmosphere and the area of the Arctic ice sheet is statistically significant in two consecutive years. In X-axis I marked the year from which each analysis series started.

The left side of the figure (yeasts 1979-2001) is according to the hypothesis, and the blue columns - i.e. number of years needed for statistical significance - are shortening from left to the right as predicted by the climatic models. However, starting from 2002 there are no consecutive two years with statistical significance, and therefore these columns are marked with red color. And their height is simply the number of data years used for each analysis. 

Thus, my analysis suggests that the prediction based on climatic models are supported by data from 1979 to 2001, but thereafter there is a strict contradiction between the models and observations. Normally such a discordance between observations and theory is used to falsify scientific hypotheses. I have, however, not seen that the such a decision would have been made or even discussed among the community of climatic researchers.

* * *

Before ending this blogpost, I would like to point out that the most recent daily measurements of the Arctic sea ice extent have shown an extremely interesting change, where the relative extent of the ice has decreased compared to previous years. As a result, right now (January 5th) the size of the Arctic sea ice is the second smallest ever measured (for the fifth day of each year) despite the fact that e.g. in 5th November it was only at 11th position. 

Therefore it will be extremely interesting to follow how the Arctic sea ice develops in this year. Will its development return back to the development predicted by the climatic change, or will the last weeks´ phenomenon turn out to be only a temporary exception caused by e.g. exceptional weather conditions in the Arctic region.

Finland and NATO - problems to be solved

Right now the most important news from Finland is the future of our security policy. Should we join the NATO or remain a kind of a neutral country we have been since the second world war - also before the WWII? 

The change in the attitudes of our citizens has been quick. Before the Russian attack to Ukraine a vast majority of Finns supported neutrality, but now more than 60 percent of us support allying with the Western defense system.

The most important issue to us will be the delay between the submission of the application and the decision by NATO. During that time Russians will most probably use all possible hybrid means to press Finnish politicians. And actually, that has already started, as the embassy of Russia asked Russian speaking people in Finland to inform them about their possible experiences of discrimination in our country. 

Russia also mentioned that Ukraine could be a similar neutral country as Austria or Sweden but remained quiet about Finland. So, that raised a question we Finns have been thinking thereafter. That is, what does that mean? 

More specifically, does Mr. Putin have other thoughts on us - perhaps something similar Mr. Stalin had in 1939, when he - with the support of German Nazi-leader Adolf Hitler - tried to occupy us in a winter war, where at least 200 000 soviet soldiers were killed and even more injured. Many of them Ukrainians.

This note is a landmark of the Thoughts of the Professor blog. I have previously published translations of my Finnish blog here, but it turned out that my motivation quickly decreased to zero. Therefore I decided to give up with translations, and write also in this blog unique texts, that are independent of my national blog. I hope you will find this interesting.
