In an era where change itself seems to be the subject holding people's attention, NASA proudly presents a spectacular new movie depicting a changing Earth. Called FROZEN, it showcases a major part of our home planet in ways never seen before.
FROZEN features the global cryosphere, those places on Earth where the temperature doesn't generally rise above water's freezing point. As one of the most directly observable climate gauges, the changing cryosphere serves as a proxy for larger themes. The movie brings the Earth alive, projected onto spherical movie screens hanging in the center of darkened theaters. Turning in space, the sphere becomes a portal onto a virtual planet, complete with churning, swirling depictions of huge natural forces moving below.
Ice shows deep, persistent, global changes more readily than other kinds of geographic features. Where the world stays cold over time, liquid water freezes. Where the world persistently grows warm, ice in its many forms thaws. It's natural, therefore, to focus substantial attention on those parts of the Earth that historically depend on ice. Polar caps, high altitude glaciers, permafrost covered plains and many other cold regions play a vital role in global climate sustainability. As those regions and other cold places change, so changes the overall condition of the planet. As a proxy for climate change, changing ice opens a dialogue about a variety of subjects, from the importance of gathering long terms records about the Earth, to the techniques scientists use to study our home from space, to the day-to-day habits that individuals and communities around the world adopt in relation to their environment.
