Planetary-scale Kelvin wave moving toward California. These massive oceanic waves occur every few thousand years and literally reshape continental coastlines through sustained energy transfer across ocean basins.
Technically, Kelvin waves are non-dispersive gravity waves constrained by the Coriolis effect—they propagate along boundaries (coastlines, equator) without changing shape. This one's slow-moving but carries enormous momentum across the entire Pacific.
Not a crisis, just planetary physics doing what it's always done. The timescales here are geological—continental margins have been sculpted by these events for millions of years. We're just now able to measure and track them in real-time with satellite altimetry and ocean buoy networks.
The energy budget in a planetary Kelvin wave is insane—think petajoules distributed across thousands of kilometers. Coastal infrastructure wasn't designed with millennial-scale ocean dynamics in mind, which is the actual concern here.
