Polar Extremes is an upcoming NOVA special hosted by paleontologist and Sant Director of the Smithsonian Institution's National Museum of Natural History Kirk Johnson, immerses viewers in a scientific quest to explore the unexpected secrets of our planet's polar past. Following a trail of strange fossils found in all the wrong places-beech trees in Antarctica, hippo-like mammals in the Arctic-the film uncovers the bizarre history of the poles, from miles-high ice sheets to warm polar forests teeming with life. What can Earth's dramatic climate history reveal about our future? A two-hour special premieres February 5 at 8 pm on PBS. For more dates and times go to www.pbs.org/polar-extremes.
