Executive Producers And Host Discuss The Making Of NOVA's 'Polar Extremes'

NOVA’s multiplatform polar experience — including a 10-part digital series and game-based Polar Lab — allows us to travel from pole to pole and across time, 650 million years ago to present day, to discover what the past tells us about what might happen to the poles — and the rest of our planet — in the future. "Polar Extremes," a one-night, two-hour special hosted by renowned paleontologist Kirk Johnson, premieres Wednesday, February 5 at 8pm on WGBH 2.
