Elegantly modeling Earth’s abrupt glacial transitions

Milutin Milankovitch hypothesized that the timing of glacial transitions has been controlled by the orbital parameters of the Earth, which suggests that there may be some predictability in the climate, a notoriously complex system. Now researchers propose a new paradigm to simplify the verification of the Milankovitch hypothesis. The new ‘deterministic excitation paradigm’ combines the physics concepts of relaxation oscillation and excitability to link Earth’s orbital parameters and the glacial cycles in a more generic way.
