Americans have collectively decided, through our elected representatives, to boost U.S. population to Chinese/Indian levels, mostly via low-skill immigration:
Democrats now agree with Republicans, apparently, that cheap oil/gas is desirable and that Climate Change (TM) need no longer be fought by cutting CO2 emissions.
If the heat in the Lower 48 becomes unbearable and the seas inundate Boston, New York City, DC, Miami, and other major coastal cities, Alaska seems like a natural evacuation destination. There is plenty of high ground in mountainous Alaska and the weather is pleasantly cool all year along the coast. The all-time record high for Juneau is 90 degrees, set in July 1975, and the average daily high temp for Juneau in July is 63.
One critical problem with life in the low-density parts of SE Alaska is transportation. Today’s airplanes typically can’t fly in the 0/0 foggy conditions that often plague this part of the country. There isn’t a high enough population density to support frequent nonstop flights among the various towns, nearly all of which are cut off from any road network, e.g., due to being on islands. The fabled Alaska Marine Highway (see Chapter XII of Travels with Samantha) is expensive and infrequent, perhaps partly due to the Jones Act that requires them to use U.S.-built vessels and that prevents an Asian-run company from offering competitive service. Below, the Alaskan-built MV Hubbard (cost $60 million in pre-Biden dollars; a “dayboat” that holds 53 cars; launched 2019):
What about a machine that can fly itself the 40-80 nm. legs that are required to get around this part of the world and that can navigate safely around terrain via reference to GPS and a database? That’s the autonomous electric aircraft (vertical takeoff and landing isn’t necessary, actually, since nearly all of these places have high-quality airports/runways, but eVTOL would work). Could that encourage more Americans (and “New Americans”) to settle in this part of the U.S.? Want to see a friend or shop? That will be a 20-minute flight. Need to see a medical specialist? The regional hospital in Juneau can be reached easily and you’ll be home in time for dinner. Need to be evacuated to Seattle or Anchorage for specialized hospital care? That’s done with a 20-minute electric air ambulance ride followed by a jet flight.
We’ve already seen this trend to some extent with islands for the rich. Martha’s Vineyard and Nantucket weren’t beyond peasant means until private jet ownership became common. A house near ACK had no value to a rich Texas family until the rich Texans got their Gulfstream and could fly directly to ACK rather than flying commercial to Boston and taking a piston-powered airplane or the road+ferry.
