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.
