Emergency Alert System tones are a familiar part of American broadcasting, designed to interrupt programmes with urgent warnings, and their stark sound has long been repurposed online for comedy. Bass-boosted versions became popular in meme editing because the exaggerated low end makes an already serious alert feel even more dramatic and unhinged. Applying that treatment to Antarctica, a place with no large population to warn, turns the format into a joke about overblown danger. The clip now circulates mainly as a reaction sound for videos that treat trivial events like emergencies.
