Caption: The sediment archives obtained during ocean drilling programs give scientists a glimpse into Earth's climatic history. Inset: Deep sea sediment cores across the Paleocene-Eocene boundary. The sections of light brown color consist mainly of calcium carbonate, whereas the dark red/brown section is a clay layer, representing the onset of the interval of intense global warming and ocean acidification 55 million years ago.
