Glacial cycles aren’t random; they follow a predictable rhythm dictated by Earth’s orbit. A study analyzing climate records ...

Earth naturally cycles between ice ages and warm periods based on three astronomical cycles: precession (Earth’s wobble), obliquity (tilt), and eccentricity (orbit shape). Scientists can now predict ...

Its alignment with the rest of the galaxy moves — specifically, it "precesses." Precession describes how the alignment of the ...
