Princeton University-led researchers have extracted 2 million-year-old ice cores from Antarctica — the oldest yet recovered — that provide the first direct observations of prehistoric atmospheric conditions and temperatures. They used data from the ice cores to answer long-held questions about how our current colder, longer glacial cycle emerged. The cores were collected in the remote Allan Hills (pictured), where high winds draw ancient ice toward the surface.
CCI teams with Princeton to analyze 2 million-year-old ice cores
Three University of Maine Climate Change Institute scientists are part of a Princeton University-led team that analyzed 2 million-year-old ice cores from Antarctica to provide the first direct observations of Earth’s climate when furred early ancestors of modern humans still roamed. Read more
