In How Ice Provides a Reflective Shield on Earth, geologist Iain Stewart explains that ice is a unique substance. Because it floats and is reflective, it provides a reflective shield for the Earth and impacts how much energy is absorbed, which impacts the climate. The changing amounts of ice on the planet also impact how modern man has adapted. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
