New research suggests Earth’s climate can swing wildly on surprisingly short timescales — even during hot, ice-free greenhouse periods. By studying ancient sediments from the Late Cretaceous, scientists uncovered repeating climate shifts tied to tiny changes in Earth’s orbital wobble. These cycles may have repeatedly pushed the planet between humid and arid states every few thousand years.
