Collecting Climate Change Clues in Antarctica
Jun 3, 2008 | Run Time: 04:14
Mark Kurz from Woods Hole Oceanographic Institution discusses how he can find out the ages of rocks in Antarctica to discover when ice sheets and glaciers advanced and retreated on the icy continent. That knowledge, in turn, helps scientists learn more about how and why Earth's climate changed in the past, providing clues to determine how humans are affecting Earth's climate today, and the impacts climate change will have on humans in the future.
