Uncover the bizarre history of the poles, from miles-thick ice sheets to warm polar forests teeming with life and the trail of fossils from the beech trees in Antarctica to redwoods and hippo-like mammals in the Arctic that led scientists down the path of discovery.

This episode of Nova, ‘Polar Extremes’ questions if the invisible, odorless gas called carbon dioxide was a visible solid material on the ground, would our perspectives change on the amount of carbon emissions we emit into the atmosphere. The episode also delves into how the Arctic transformed from a warm swamp to today’s icy glaciers over the course of fifty million years, the fluctuation of Earth’s climate over 500 million years, what is causing Greenland’s biggest glacier, Jakobshavn, to melt, how humanity is accelerating the heating of the Earth’s climate, and much more. Tune in to learn about how Earth’s climate has transformed over the course of time.
