PRINCETON, New Jersey, Dec. 12 (TNSJou) -- The Princeton Environmental Institute issued the following news:
The last million years of Earth history have been characterized by frequent "glacial-interglacial cycles," large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These cycles are triggered by subtle oscillations in Earth's orbit and rotation, but the orbital oscillations are too subtle to explain the large chan . . .
