Ice on Earth advances and retreats every 100,000 years. Scientists have found that this rhythm is set not by the planet's complex chemistry, but by a simple solar echo, stretched out by the ocean. This new approach could change future climate predictions.
🎯 The ocean's mute: The 400,000-year orbital cycle exists, but in the ice age record it is absent — the ocean dampens slow oscillations, leaving only the 100,000-year rhythm.
