Polar bears are the draw for most visitors to Spitsbergen, the largest island in Norway's Svalbard archipelago. For geoscientist Lee R. Kump of The Pennsylvania State University, however, rocks were the allure. In the summer of 2007 Kump flew to this remote Arctic Ocean island to find rocks that might offer fresh insights about one of Earth's ancient episodes of global warming: the so-called Paleocene–Eocene Thermal Maximum, or PETM. In that event, some 56 million years ago, global temperatures rose 5 degrees Celsius in the course of a few thousand years—a mere instant in geologic time.

This slide show features highlights of Kump's Arctic quest to find those rocks

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
