Hey, Corey here. We've had an influx of new listeners, and so I just want to make sure that if you are new to the podcast, you don't just jump in and start listening to these daily episodes which we've been doing. Please go back and listen to the first at least eight episodes so you have an idea of what collapse is, what it is that Corey is talking about. Also, if you've been with us for a while and you're enjoying the content, please join us on Patreon. We would love to see you there. There's a link, as always, in the description. All right, I will probably be bringing this up a couple of times over the next few days just to uh catch everyone who might not listen to every episode. I'm gonna be out of town for a solid ten days.
Work has got me traveling out of the country, and so I am not gonna really have access to record. I'm gonna try and record a few extra episodes if I can, if I have time before I have to leave to fill in for some of that time. But But yeah, just be forewarned that there's there may be a full almost two weeks in which I'm not posting to the podcast. I haven't died. I haven't fled. I'm just doing the daily grind that one has to do to continue surviving in this uh fun capitalist world. So with that, uh today's episode, I want to talk a bit about a new piece of research that came out that I thought was really interesting in regards to the impacts of sea level. Level rise on specific areas of the world, which interestingly will have the greatest impact on the most people.
So this is from Fizz.org. They are highlighting some research from a group of researchers out of the Technical University Munich, as well as Tulane University in New Orleans. The title of the paper is Subsidence: More than Doubles Sea Level Rise Today along densely populated coasts. The article of the uh article itself in Fizz.org is sea levels rising dramatically in some areas due to land subsidence. The opening paragraph of the article says densely populated coastal regions in many parts of the world are particularly vulnerable to flooding. The sinking of land masses exacerbates the impacts of rising sea levels in these areas, according to a new study by researchers. So this doesn't mean that sea levels
Level itself is necessarily rising more in those cities, but the cities themselves are sinking. We've talked a bit about subsidence. Uh recently we talked about Jakarta and the danger presented there because of it. But interesting to note that all over the world, while the seas are rising, all of our or most of our major cities are sinking. It's a sort of double whammy and one that is not necessarily expected. Or previously understood when we make our sea level rise projections. If, for example, a city is sinking at the same rate that the sea is rising, it will half the amount of time that it takes for that city to become persistently flooded. Now, this is not to say that, you know, densely populated cities are necessarily the most important coastlines, that it that it's the worst-case scenario that it's happening in these areas, because obviously so much of our coastlines are used for agriculture.
And seawater encroachment turning soil brackish is a huge problem for feeding people in the future. But when we're talking about things like mass migration, economic loss, individual economic situations, a very significant number of people live on the coastlines of the world in major populated cities. Those people will continue finding themselves with uh tougher times getting insurance, and without insurance. Flooding's not covered, the loss of homes for many people can mean total economic destruction, no ability to recover from that. Same thing goes for all of the businesses, the places of work in those areas, and the economic catastrophe that would be losing all of those jobs and the production and things that go with that.
Not to mention supply chain issues that come from port cities experiencing this same problem. You can understand. The various consequences that could come from an increased rate of sea level rise in these places.
