Ice and Snow
On Christmas Eve, Andrew Marr explores the mysteries of snow and ice. Michelle Paver's novels dwell in the darkest places: an Arctic hut in midwinter haunted by ghosts, an isolated mountain peak, and a prehistoric frozen forest. She explains the appeal of these inhospitable settings, and asks why the cold still terrifies us.
Ben Saunders knows the sounds and smells of ice better than most. As one of the world's leading polar explorers he has skied to the North Pole and completed Scott and Shackleton's aborted trip to the South Pole. He describes the exhaustion, frustration and wonder of life on a frozen sea.
Materials scientist Mark Miodownik knows that liquids are not to be trusted, even when frozen solid. His latest book, Liquid: The Delightful and Dangerous Substances That Flow Through Our Lives, unpicks the cracks, creaks and crystals of ice.
Poet and writer Nancy Campbell set out from the world's northernmost museum to understand our fascination with ice and snow. Her new book, The Library of Ice: Readings from a Cold Climate,brings to life the people who dwell in these icy landscapes, many of which are now disappearing.
