Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past.

By tracking seismic waves from earthquakes that have passed through the Earth's inner core along similar paths since 1964, the authors of the 2023 study found that the spin followed a 70-year cycle.
