PP53A:
Astronomical Forcing of Past Climate II Posters
Session ID#: 8954
Session Description:
It has long been known that the glacial – interglacial cycles archived in geological records vary at orbital frequencies. The most accepted theory connecting glacial-interglacial cycles to the variations of the Earth’s Orbital Parameters was first presented by Milankovitch, which has since then been elaborated upon several times and has developed into the astronomical or Milankovitch theory of climate change. However, the astronomical theory of climate change fails to explain certain features of Earth’s climate history, such as the 41-kyr dominance of obliquity in the late Pliocene-early Pleistocene, the onset of the Mid Pleistocene Transition, the 100,000-year problem, etc. We encourage contributions focused on answering these pertinent questions based on paleoclimate proxy studies, theoretical and/or modeling studies. This session also aims to bring together recent studies of global and regional climate responses to astronomical forcing at different time scales (e.g. Miocene, Pliocene, Quaternary) when the climactic regimes were different.
