Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

Altered Ocean Temperature Gradients Are Key to Miocene South Asian Monsoon Evolution

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Indian Ocean sea surface temperature (SST) gradients influence South Asian summer monsoon (SASM) strength. Middle Miocene proxy records show reversed Arabian Sea zonal gradients (warmer west than east) and reduced Indian Ocean meridional gradients compared to today—patterns coupled models cannot reproduce, hindering accurate SASM simulation ...
