During the last ice age, glaciers covered the entire northern part of our continent, shaping mountains and carving valleys. Today, most of the earth's glaciers are found in Antarctica and Greenland, but there are glaciers on every continent, including Africa, most commonly above the snow line. Tim Creyts, a glaciologist with the Lamont-Doherty Earth Observatory, Earth Institute, Columbia University, explains what glaciers are, how they move and sculpt the landscape, and how climate change is affecting glaciers around the world.

Sea level rise is just one of the ugly faces of climate change. A dangerous one too. Especially for the US, which has 20 of the most threatened coastal cities in the world. With reports and interviews from the beaches of Southern Florida, the glacier fields of Greenland, the coastal wetlands of Louisiana and the streets of New York City, Rising Seas takes an in-depth look at the potentially devastating impact of sea-level rise on two major American cities in addition to the Gulf Coast’s vulnerable marshlands and its oil and gas industry. The special also captures the sights and sounds of Greenland’s ice sheets, which are melting more rapidly than anyone had anticipated, unleashing huge quantities of water into the North Atlantic. That, in turn, is driving the unusually fast sea rise along the coast.

There's a world that exists exclusively below the ice, extending thousands of feet in elevation on Mount Hood in Oregon—it's a world ade up of three recently discovered glacial caves. Amelia Templeton is a reporter for Oregon Public Broadcasting's Earthfix Project. She describes her descent into Mount Hood's glacial caves and OPB's multimedia project, "Thin Ice: Exploring Mount Hood's Glacier Caves."
Krulwich Wonders: Strange-Looking Tombstone Tells Of Moving Ice, Ancient Climates And A Restless Mind

It's a tombstone like no other. A rough, clumpy hunk of granite, carried across Europe on a sea of ice, dumped in a valley, shipped across the Atlantic, lugged to Massachusetts — all to honor a restless man.
