| What Clues To the Future Can We Learn From the Past |
Could we be headed “back to the future,” to the last time crocodiles roamed Greenland, and pine forest covered Antarctica? Ice cores, corals, rocks, and fossils in ocean sediments tell Earth’s climate story and reveal that today’s carbon dioxide levels are unprecedented since humans evolved on a planet cooled by polar ice caps. Join Harvard University professor Dan Schrag, PhD, paleoclimatologist, geochemist, and Director of Harvard University Center for the Environment as he visits a high school classroom to show how scientists unlock the mysteries of Earth’s past.
