Short summary

We studied a short-lived episode of major warming ~56 million years ago, often seen as a past analogue for modern climate change. We developed a scheme to correlate biological signals from this warming period across six sediment cores from the US East Coast. Based on the occurrences and distribution of organic remains of planktonic microfossils, we can correlate events in time, allowing detailed reconstructions of how climate and environments changed regionally during this extreme warming.
