November 2025 in Review

Most frightening and/or depressing story: Wait, I actually had trouble coming up with a frightening or depressing story this month! It’s not because I was in a particularly good mood. Okay, I’ll go with all the terrible things identified in Project Censored’s yearly roundup of terrible things. These include PFAS, melting ice sheets, police violence, and the generally sorry state of the Native American community.

Most hopeful story: RENEWABLE ENERGY IS NOW CHEAPER THAN FOSSIL FUELS, AND ANYBODY WHO CLAIMS OTHERWISE IS EITHER MISINFORMED OR LYING. Note I said “misinformed”, because I try to be nice and “ignorant” is not a nice word. But they are synonyms. Despite the propaganda coming from the U.S. fossil fuel industry, government, and press, the renewable energy transition is happening and the fossil fuel stranded assets problem (for that industry) is real. Speaking of propaganda, Noam Chomsky is 96, still writing, and surer than ever that people don’t want war and only acquiesce to it because of the propaganda machine.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: The Tyranny of Small Decisions posits that many small but well-intentioned decisions made at inappropriately low levels within an organization can cause it to stray from its mission.

July 2025 in Review

Most frightening and/or depressing story: In case we still don’t have enough feedback loops to worry about, loss of Antarctic ice could also trigger volcanoes under Antarctica.

Most hopeful story: The Great Lakes states, provinces, and cities may be the best climate havens North America has to offer.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Policies to increase housing supply in the most economically dynamic cities can theoretically accelerate economic growth, since housing supply is not expanding fast enough and is therefore holding economic growth back. A lot of discussion has been focused around zoning, which is a local matter. But I offered some additional suggestions: investment in better transportation and communication infrastructure to reduce the friction of working across distances between homes and offices, effectively enlarging housing markets. And serious investments in construction productivity, which has been flat in the U.S. for decades. Ideas include more factory-based modular components. The U.S. has tried and failed at this before, but of course China is now leading the way. AI should also be pretty good at construction scheduling and logistics. The U.S. is somewhat successfully partnering with Korean ship-building expertise, at least on a small scale.

11 square miles of moss

11 square miles covered with moss since 1986 just doesn’t sound all that dramatic to me, but apparently for Antarctica this is a big deal and not a good sign. Apparently it has been happening for awhile in (originally sarcastically named?) Greenland, and it is not as big of a surprise there, but it is still not a good sign.

the Thwaites glacier

The Thwaites glacier in Antarctica is roughly the size of Florida, according to USA Today. It is held back by a Game of Thrones style ice wall (seriously, I wouldn’t be surprised if pictures of this or similar structures inspired the visuals in the show, if not the original concept. I always thought George R.R. Martin’s original concept might have been inspired by Hadrian’s wall, although I think a sprightly child could jump or climb over that.) Over the next few years to decades it could slide off the continent, float away, melt, and raise average sea levels by a foot. Or “up to 10 feet, if it draws the surrounding glaciers with it.”

I have in the back of my mind that we are looking at “a meter of sea level rise over a century”. This is bad, but it leaves a few decades for me to take my children on beach vacations not too different from the ones my parents took me on in my own childhood, wrap up raising said children to adulthood in my home not too far from the Atlantic coast, eventually sell my coastal real estate empire (consisting of the family home and a small condo I have hung on to for an older relative) at a reasonable market price, and advise the adult children not to buy property anywhere near the coast. I myself would not live to see the worst effects, and as much as I care about my children and their hypothetical children on down the line, it is just human nature that I don’t sit around worrying too much about risks that far into the future.

There are some numbers in this article that suggest I might not have decades to accomplish this long-term plan. The numbers are a bit confusing and conflicting, however.

  • The ice shelf (official name for the Game of Thrones wall) could collapse in the next 3-5 years. This would be the “beginning of the end” of the glacier, which would then begin sliding into the sea.
  • Then there will be a “dramatic change in the front of the glacier probably within a decade”.

The article refers to “rapid” sea level rise, but it doesn’t quantify that, so I don’t have any really new or good insights on whether my 1 meter in 100 years idea is too rosy. I still don’t think coastal property is a great investment anywhere in the world. A few rich, small, low-lying, technocratic countries like the Netherlands and Singapore will probably do whatever it takes to physically alter their coastlines and raise their urban areas, but many other countries will just sit on their hands.
