Improving Climate Models Through New Insights on Long-Term Inter-Hemispheric Climate Synchronicity From Speleothems

Grant number: DP0773700

Abstract

It is important that palaeoclimatologists continue to improve understanding of how the Earth responds to climate forcing, so that climate models can be rigorously validated and refined. Since the Earth responds to most of this forcing over time scales that exceed the length of instrumental weather measurements, the recovery of datable palaeoclimate archives that are highly sensitive to past climate changes is essential. Our project will provide important new palaeoclimate data from both hemispheres on how key regions of the Earth responded to past climate changes. This will bring improved understanding of past oceanic-atmospheric processes that can be fed into climate models, ultimately prod..
