      • CLAY CORES: This is what the drill core segments look like inside those boxes. They are composed almost entirely of mud and clay laid down in an ocean basin millions of years ago. Kump's analyses have revealed that the PETM climate change was not nearly as rapid as the human-caused changes unfolding today... Courtesy Lee R. Kump, The Pennsylvania State University
      • A STROKE OF LUCK: It turned out that a Norwegian mining company had cored, years earlier, through sediment layers covering the PETM episode. Kump and the other scientists were led to a large metal shed on the outskirts of Longyearbyen, the largest settlement on Spitsbergen, where the core is now housed, since cut into long cylinders stored in hundreds of flat, wooden boxes...

      • AT LAST: Somewhere within the modest embankment of ancient mud and clay along this stream resides a previously undiscovered record of the PETM climate fever. Courtesy Jane Francis, University of Leeds

      • NOT FAR TO GO: Nagy pauses near a thin, brown layer of volcanic ash that geologists have used to date this rock formation. It is a firm clue that the PETM outcrops are not far away.
      • FOLLOW THE EXPERT: Kump [left] gets directions from Jenö Nagy, the group's expert on the local geology. A professor at the University of Oslo in Norway, Nagy led Kump and others to the PETM outcrops. Courtesy Jane Francis, University of Leeds

      • SNOW OR FERNS?: Getting to the rocky outcrops that might entomb clues about the PETM meant a rugged, two-hour hike from the former coal-mining village of Longyearbyen. As Kump [right] observed slippery pockets of snow and stunted plants, he says he imagined a time when palm trees, ferns and alligators probably inhabited this area...

      • GROUP EFFORT: Lee R. Kump, a geoscientist at The Pennsylvania State University, met up in Spitsbergen with a group of researchers from the U.S., England, Norway and the Netherlands. These 18 scientists, working together under the auspices of the Worldwide Universities Network, had reason to believe that rocks from this part of the Arctic could provide the most complete record of the Paleocene–Eocene Thermal Maximum (PETM) yet discovered...
