A fossiliferous core from a site in Maryland

Fossiliferous core from site in Maryland that was once underwater. Researchers studying the cores found a rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged warming for many thousands of years.

Read more about this research, supported by the National Science Foundation (grant OCE 1416663), in the PennState news story Ancient climate change triggered warming that lasted thousands of years. (Date image taken: unknown; date originally posted to NSF Multimedia Gallery: May 17, 2019)
