  • Jones Act Waiver

    Jones Act Waiver
    Jun 2 2026
    This week we talk about the Merchant Marine Act, trade routes, and incentives.We also discuss Wesley Jones, foreign competition, and artificial monopolies.Recommended Book: The Quantum Thief by Hannu RajaniemiTranscriptIn 1920, the then-Senator for the state of Washington, Wesley Jones, who was also the chairman of the Senate Commerce Committee, introduced the Merchant Marine Act as a method by which the American merchant marine could be sustained and remain competitive in the face of external competition, and in the wake of the destruction of a bunch of ship during WWI.The US Merchant Marine is all the commercial water-going vessels that are US flagged, and the crews of these vessels. During peacetime, these boats and ships conduct trade and other services along the United States’ coasts and throughout its internal waterways, its rivers and lakes. During wartime, these vessels and their crews are tapped to help move troops and weapons and supplies for offensive or defensive military efforts.The theory of this proposed Act, then, was to ensure that the US Merchant Marine would remain well-funded and well-taken-care-of, because lacking some kind of government support, there was a good chance it would either slowly degrade, not having enough business to pay for itself, or—and this has been a persistent concern for similar pseudo-fleets of merchant vessels around the world for the past few hundred years—it would fall into disrepair because it would be outcompeted by vessels and crew coming in from elsewhere that would charge lower prices, creating unsustainable economics for the locals and thus slowly degrading this economic and military asset.When this Act was proposed, in 1920, the preservation of this asset was on the mind of many US politicians, as the world had just emerged from World War I, and in that and previous conflicts, the US Merchant Marine had been pretty vital to ensuring the US eventually came out on the right side of things. It was also fundamental to the rebuilding of the US economy following difficult conflicts, because the moving of cargo from city to city along coastlines, and throughout long expanses of rivers—getting food from place to place, getting building supplies where they need to go—has always been important, especially following periods in which there isn’t a lot of building going on, and when supplies chains are reoriented toward other purposes, like fighting.So in addition to all the language the helps regulate trade within US waters and between US ports, and which says how the crew of such vessels have to be treated, this Act was also meant to provide protected status to US Merchant Marine vessels and crew, giving them a pseudo-monopoly on certain types of trade activities in the US.It was also—and this is important context—meant to give Senator Jones’ state of Washington a de facto monopoly on trade with Alaska. But it was sold to the rest of Congress and the country as a means of bolstering the funds flowing into the US Merchant Marine. Section 27 of this act, often called the Jones Act, requires that all goods transported between US ports be carried by US vessels built in the US, flying the US flag, owned by US citizens and with majority US citizen and permanent US resident crews.What I’d like to talk about today are the other consequences of the Merchant Marine Act of 1920, and in particular the Jones Act component of it, and why there’s been renewed opposition to the Jones Act in recent months.—The logic of the Jones Act, at least on the surface, is pretty straightforward.If you’re worried about foreign competition coming in and taking all the shipping jobs, swooping in from areas where crews aren’t paid as much, and where ships can be built cheaper, so they can charge less than US-made and -manned ships, all you have to do is require all the ships and people on the ships are of US-origin, and you’re good to go. Those foreign competitors aren’t allowed to take the jobs, and that sets the standards in a different place, allowing US vessels and their crew and owners to charge whatever they need to charge to sustain themselves.This, in theory at least, should also stimulate the US ship-building industry, as that monopoly means anyone who builds new ships stands a pretty good chance of making their money back. After all, there’s no dramatically cheaper competition out there, so you’ve got relatively little downward price pressure and seemingly plenty of customers, because there’s a lot of US coast, and a lot of internal waterways that have traditionally be used for trading purposes.In practice, though—and this isn’t uncommon with protectionist measures; things that seem like they should work for the intended purpose actually leading to other, less ideal outcomes—the Jones Act is often blamed for increasing prices on pretty much everything, and for increasing prices dramatically in places like Hawaii, Alaska, Puerto Rico, and ...

  • 2026 DRC Ebola Outbreak

    2026 DRC Ebola Outbreak
    May 26 2026
    This week we talk about the Democratic Republic of the Congo, malaria, and healthcare infrastructure.We also discuss militants, Uganda, and the Bundibugyo virus.Recommended Book: We Should Get Together by Kat VellosTranscriptEbola, which is more formally called Ebola Virus Disease or Ebola Hemorrhagic Fever, is caused by an infection by a type of RNA virus called an orthoebolavirus.There are six known species of orthoebolavirus, and four of them have at some point infected and caused illness in humans. Those four are the ebola virus, sometimes called the Zaire ebolavirus, which historically has been the strain responsible for the biggest, most devastating outbreaks of this disease, the Sudan virus, the Taï Forest virus, and the Bundibugyo virus, the latter three each causing a variant of the disease that carries the same name.The other two orthoebolavirus species that we know of, the Reston virus and the Bombali virus, have been known to infect animals, but have not, at this point at least, been known to make the jump to human hosts.Ebola symptoms vary a bit between specific viruses and between hosts and infection conditions, but in general those who are afflicted by ebola begin to experience symptoms between a few days and a few weeks after infection, and they’ll start by experiencing cold and flu-like symptoms, like fever, sore throat, headaches, and general muscle pain. Soon after that, though, they’ll start experiencing diarrhea and rashes, they’ll begin vomiting, and they’ll begin to experience liver and kidney dysfunction, and around that same time, they’ll start to bleed internally and externally.Once infected, a person has between a 25 and 90% chance of dying, depending on the strain of ebola, and if they die, usually due to what’s called hypovolemic shock—a severe and sudden loss of bodily fluids, including blood—they usually die between 6 and 16 days after those first symptoms are reported.What I’d like to talk about today is a new outbreak of ebola centered in the Democratic Republic of Congo, and why this one stands out from other recent outbreaks in the region.—Ebola was first officially reported in medical literature in 1976, mostly in sub-Saharan Africa, and there have been semi-regular outbreaks in that region, of various sizes ever since, and very likely before that, too.This disease is spread through direct contact with the body fluids of someone who’s infected, and it’s thought that this is probably how the disease made the leap from animals, like primates, to human beings: locals sometimes come into close contact with local primates, either while just coexisting, or while hunting bushmeat, hunting monkeys for food.It’s thought that fruit bats serve as hosts for the virus, long-term, and it then spreads to other animals, and then sometimes to humans, in some cases causing illness along the way in those other species, but not always; bats are not negatively afflicted by it, for instance, but humans very much are.Despite not being an airborne pathogen, so it’s not spread by coughing or talking too close to someone, like a cold or Covid-19, ebola can still be spread person-to-person through bodily fluid contact. That means fluids like saliva and blood and semen and breast milk, and research has shown that even after someone survives and recovers from ebola, the disease can linger in their fluids for months. So if someone catches it, survives, and then breast-feeds their child, or kisses or has sex with their partner, or gets a cut and then someone else comes into contact with their blood, like a health worker, that can lead to the transmission of the disease, despite their having been well and seemingly fully recovered for weeks or months.That lingering contagiousness is a confounding factor with this disease, as it requires that people be very careful, even to an antisocial degree, and even well after it seems like that’s no longer necessary, because they feel good and healthy again.This also means that if someone dies of ebola, contact with their bodies can be incredibly dangerous. And past outbreaks have stemmed from or been further enflamed by locals wanting to perform community funerals and wakes, during which the body is often on display and touched by attendees, and that has led to further spread of the disease—which in many cases is difficult to tie back to that wake, because again, symptoms don’t arrive right away, and ebola symptoms are similar to what locals experience all the time from other afflictions, like colds and malaria.This past week, in Bunia, which is located in the Democratic Republic of the Congo, locals stormed a regional hospital in an attempt to recover the body of a beloved local figure who died of ebola. In the process, the hospital’s isolation ward, which was being used to keep ebola victims separate from everyone else, to keep the disease from spreading further, that ward was burned to the ground.There are no vaccines ...

  • Super El Niño

    Super El Niño
    May 19 2026
    This week we talk about oceanic surface temperatures, trade winds, and global climate change.We also discuss the Polar Jet Stream, hurricanes, and climate models.Recommended Book: Kleptopia by Tom BurgisTranscriptUnder normal circumstances, the Pacific Ocean’s average surface temperature, the distribution of heat across its vast expanse, is moderated by trade winds that blow east to west along the equator, which help move warm water from South America over toward Asia.Those winds are called trade winds because, back during the European age of Exploration, they helped ships from Europe head west toward Asia and the Americas. And these winds form in part because of the Earth’s rotation, the Coriolis effect funneling air toward the equator, where it is then more concentrated and thus potent, which is useful if you’re trying to move a ship with sails, but also serves the purpose of moving warm water from one part of the ocean to another part of the ocean.As those warmer surface waters are shifted from the Americas to Asia, water is pulled up to the surface from lower down in the ocean as part of a process called upwelling. This process results in cooler temperatures on the surface, because lower down, oceanic water is colder, and that lower-down water is also more rich in nutrients, which has the knock-on effect of stimulating more biological activity along these cooling surface waters.That’s the normal state of things in the Pacific Ocean.There are sometimes deviations in this norm, however, that result in very different outcomes; these deviations are broadly called the El Niño Southern Oscillation Cycle, and that cycle consists of opposite El Niño and La Niña climate patterns.During La Niña patterns, trade winds are more powerful than usual and they shove a lot more of that warm surface water to Asia than is typical, and that has the net impact of moving more deep-down cold, nutrient-rich, ocean water to the surface.This, in turn, nudges the Polar Jet Stream, which is a channel of fast-moving, westerly winds that lives about 30,000 ft or just over 9000 meters up in the sky, and which crosses both warmer, mid-latitudes and far colder Arctic latitudes, further north. The Polar Jet Stream is responsible for moderating or intensifying weather patterns around the world, and like the trade winds, it’s influenced by the spin of the planet, but it’s also adjusted by surface systems, like the temperature of the Pacific. So the arrival of a La Niña pattern pushes the jet stream further north, and as a result, weather patterns change, and in North America, we tend to see drought in the southwest, heavier rains and flooding and in the Pacific Northwest and Canada, warmer winters in the South, and cooler winters in the North.La Niñas also tend to result in more severe hurricane seasons in the Atlantic basin, while suppressing hurricane activity in the central and eastern Pacific basins.El Niño, in contrast, results from weaker trade winds, which, because these winds don’t pack as much of a punch, means less warm water is being shoved from South America to Asia, and thus the surface temperature of that part of the Pacific is warmer, lacking that upwelling of cold water to replace the warm water that would otherwise be displaced over to Asia.El Niño also adjusts the location of the jet stream, but in the opposite direction, pulling it south of its usual spot. That then causes more heat and dryness across the northern US and Canada, but makes the southern US and Gulf Coast a lot wetter, leading to more flooding.What I’d like to talk about today are predictions about an anticipated upcoming El Niño climate pattern, and why some climate scientists are warning that it could be a doozy.—Climate scientists with the US’s National Oceanic and Atmospheric Administration, the NOAA, released new model forecasts in mid-May, and one of those models indicated that an El Niño pattern could form in the Pacific as soon as June.The NOAA puts together and releases new models on a regular basis, as the variables influencing these massively complex patterns are always changing, and the trend over the past three months has been increasing certainty about the formation of this El Niño pattern, but also an increasing likelihood that this potential El Niño would be very strong, perhaps historically so.There have been a total of 27 El Niños since 1950, when we started officially tracking such things, and we get one every three or four years, on average. The last one occurred from the summer of 2023 into spring of 2024.The current models show that we could see another one of these systems as soon as next month, then, and there’s currently a nearly 60% chance that this particular El Niño would become strong—and that’s an official designation, by the way, a strong El Niño being one that sees an ocean surface temperature increase of between 1.5 and 2 degrees Celsius—and a one-in-three chance that it could ...
