A quantitative Late Quaternary temperature reconstruction from western Tasmania, Australia

Michael-Shawn Fletcher, Ian Thomas



Late Quaternary temperature estimates from the mid latitudes of the Australian region suggest a breakdown in the tight coupling observed between oceanic and atmospheric temperatures over the recent past that has significant implications for our understanding of the response of the Earth's climate system to global climate change and orbital forcing. Here, we present a pollen-based quantitative temperature reconstruction from the mid latitudes of Australia that spans the last 135 000 years, enabling us to address this critical issue. Gradient analysis of a pollen dataset inclusive of over 1100 Quaternary and modern pollen spectra demonstrates the dominant influence of temperature over Quaterna..
