Not to mention most of NYC is pretty far above sea level.

In many cases a meter of sea level rise would flood like 2-3 blocks.

NYC itself (city proper) experienced meaningful population growth during the 2020 Census - basically grew over 600K people with an already dense footprint.

Neither city is going to flood. The people on this board are alarmist at the least.

NYC after 7 feet of sea level rise: https://coast.noaa.gov/slr/#/layer/s...h/midAccretion

Granted, 7 feet is a heck of a lot of sea level rise, but you can play with the level in this map viewer.

Both lost population relative to the 2020 Census, but Chicago lost more. Of course, the DC-Baltimore CSA is also 19% larger in area, and of course I'll acknowledge the perpetual debate on here over whether CSAs are meaningful entities.

(As someone who grew up between Raleigh and Durham, I'm firmly on the pro-CSA side.)

Both are also now middle-income countries, with large populations of people who are wealthy enough to consider emigrating.

Usually, such rearrangement happens less because the bigger city is shrinking than because the smaller city grows much faster. (See above with Chicago vs. DC, or historically NYC vs. Philadelphia or LA.) With dampened population growth nationally, I don't see a lot of large-scale league-table rearranging in the early 21st century.

On the "Baltimore" side in Anne Arundel and Howard counties, there's BWI, Fort Meade (the second-largest Army post by employment), and Columbia (a planned town with ~60K jobs). Maryland has always been relatively careful about land preservation, and the federal government plunked some giant reservations down in Central Maryland long ago. So the Patuxent River corridor hasn't been paved over, but economic linkages extend past the US-1 corridor in Laurel. (Indeed, the sprawl also touches along US 301 to the southeast of the Patuxent wildlife refuge.) Keep in mind that the two central cities' corners are 27 miles apart, much greater than the 11 miles between D & F-W.

SF & SJ fused relatively seamlessly because their respective favored quarters pretty much pointed towards one another, and the result was Silicon Valley. That hasn't been the case for other such "twin cities."

Fair 7 feet is a lot. New Jersey looks pretty bad in that picture, and it looks like Miami's water problems are coming in from inland, Everglades and swamps. I know I've seen these I kind of maps about my hometown of Boston and it's not pretty for Boston as much of the city is built on fill.

It's mostly the Meadowlands (largely swamp already) and Newark Airport (built on fill) showing up on that map.

Philly is done being a Top 10 MSA and CSA and a lot of that has a lot to do with the economic, financial, and the logistical atmosphere of that city in comparison to other American cities. It's done as a Top 10 MSA and CSA.

I don't think Atlanta will be in the Top 5 and if so, then that means that Altanta will be up there with NYC, LA, Wash-Balt, Bay Area, and Chicago, and that's a very tough plateau to crack, but Top 10, most definitely, especially with it's local economy booming and a lot of people moving to Metro Atlanta.

Also, I don't see Dallas and Houston hitting 10 million, as that figure is laughable by the 2030s. I can foresee Miami growing at a faster rate, especially if it's able to establish itself as the crypto capital of America as well as a financial and economic center in the same vein as NYC and Chicago and even a high-tech center. It all depends on those factors. Dallas is mainly real estate and high tech while Houston is mainly related to energy.

It's remarkable but it's just not sustainable as Atlanta doesn't have a commuter rail system that can connect to those far flung communities that are about over an hour away from Atlanta. if Atlanta and the state of GA can't come to terms towards building a commuter rail system that radiates out of Atlanta and I'm not just talking about MARTA, then it's practically useless to move from any American city to and locale 30 minutes to an hour and sit in traffic for over an hour just to be close to Atlanta.

With that mindset, I'd rather live in NYC, Chicago, or DC where's there's ample choices in transportation than Atlanta, where there's only MARTA and outside of Atlanta, there's no commuter rail system and you're only reliant by the automobile. Atlanta is going to have problems in the future if it can't invest in a commuter rail system, which Miami already has plus a high rail system. Besides, because Atlanta doesn't have as much int'l ties the way Miami has, eventually Miami is going to grow at a more rapid rate than Atlanta. It is what it is.
