Sea level rise and coral reef destruction could have an impact on international boundaries, according to a study by University of Sydney researchers published in Environmental Research Letters. Coral reefs form the basis for a number of claims on maritime zones, which could suddenly be in doubt if reef destruction or changes to a reef’s low-water line erase that basis. Press release.
Tom created the Topologist’s Map of the World to show how countries connect to each other. Deliberately emulating the style of a T-O map, Tom started with a Voronoi diagram and finished the map in Inkscape. Exclaves are ignored (too complicated), and islands encircle the rest of the map. Among Tom’s observations: “Some countries get really distorted—mostly when they find themselves near the centre of a continent. I’d often thought of Germany as the centre of Europe, but here, Austria and Hungary get really stretched out because they end up bordering countries on opposite sides of the continent.” [r/MapPorn]
Out today: Zoran Nikolic’s Atlas of Unusual Borders (Collins), a book that “presents unusual borders, enclaves and exclaves, divided or non-existent cities and islands.” Another compendium of geographical curiosities: a genre we’ve seen before (see, for example, the Atlas of Improbable Places, Atlas Obscura, the Atlas of Remote Islands, the Atlas of Cursed Places, Beyond the Map or Unruly Places/Off the Map) except this time it’s about borders.
The print edition of today’s Washington Post maps the fences and walls along the U.S.-Mexico border. The online version, which I seem to have missed when it was posted in October, offers a much more detailed look: it’s an interactive, scrollable map that offers a flyover view of the border, fenced and unfenced, as it passes through farms, ranches, towns and impossibly rugged terrain between the Pacific and the Gulf of Mexico.
