PlioVAR to PlioMioVAR – a treasure trove to constrain future warmer climate

Ocean and terrestrial sediment archives of past climate change are integral to our understanding of future climate change. The Pliocene and Miocene epochs are useful pseudo-analogs for future climate change. They are the most recent periods of sustained warmth where carbon dioxide concentration estimates are similar to, or higher than, modern anthropogenic levels, and the continental configuration was similar to today. A primary focus of the PAGES PlioMioVAR working group is to curate high-quality databases to facilitate comparisons with climate models and explore climate transitions over the last ~2 to 23 Myr. In this article we discuss the results and considerations of data-model comparisons, multi-proxy reconstructions, and constraining age models for ocean-sediment-based records and vegetation reconstructions
