EARTH'S FROZEN BITS You've heard about the earth's atmosphere, and probably its biosphere. Well, today we're looking for a DIFFERENT sphere. This one is the collective name of all of the coldest parts of the planet. Antarctica, of course, is generally the coldest continent. But the scientific term we're looking for includes all of the frozen parts of the Earth. That includes the Arctic ice cap and Greenland's ice sheet… along with all the planet's snow, glaciers, and even icebergs. A new report out this week documents how fast the Arctic and Greenland are changing as the planet warms up. That could mean much higher sea levels than previously anticipated. We'll talk with one of the study's authors, while you come up with the scientific name for ALL of our planet's frozen parts.
