The joy of surfing in ice-cold water
9 minutes 42 seconds
"Anything that is worth pursuing is going to require us to suffer, just a little bit," says surf photographer Chris Burkard, as he explains his obsession with the coldest, choppiest, most isolated beaches on earth. With jawdropping photos and stories of places few humans have ever seen -- much less surfed -- he draws us into his "personal crusade against the mundane."
My glacier cave discoveries
8 minutes 2 seconds
Snow Dragon. Pure Imagination. Frozen Minotaur. These are the names Eddy Cartaya and his climbing partner Brent McGregor gave three glacier caves that they were the first to explore. As the Sandy Glacier slowly slides down Mount Hood in Oregon, the caves and tunnels inside it morph annually thanks to warm water from above and warm air from below. At TEDYouth, Cartaya takes us inside these magical spaces where the ice glows in bright blues and greens, and where artifacts rain from the ceiling.

Metal that breathes
8 minutes 59 seconds
Modern buildings with floor-to-ceiling windows give spectacular views, but they require a lot of energy to cool. Doris Kim Sung works with thermo-bimetals, smart materials that act more like human skin, dynamically and responsively, and can shade a room from sun and self-ventilate.
Haunting photos of polar ice
4 minutes 11 seconds
Photographer Camille Seaman shoots icebergs, showing the world the complex beauty of these massive, ancient chunks of ice. Dive in to her photo slideshow, "The Last Iceberg."
Meet the mom who started the Ice Bucket Challenge
18 minutes 53 seconds
Remember the Ice Bucket Challenge craze this summer? Meet the mom who started it all. When Nancy Frates's son Pete hurt his wrist in a baseball game, he got an unexpected diagnosis: it wasn’t a broken bone, it was ALS, and there is no cure. In this inspiring talk, Nancy tells the story of what happened next.
Animal tales from icy wonderlands
17 minutes 55 seconds
Diving under the Antarctic ice to get close to the much-feared leopard seal, photographer Paul Nicklen found an extraordinary new friend. Share his hilarious, passionate stories of the polar wonderlands, illustrated by glorious images of the animals who live on and under the ice.
How I swam the North Pole
18 minutes 53 seconds
Lewis Pugh talks about his record-breaking swim across the North Pole. He braved the icy waters (in a Speedo) to highlight the melting icecap. Watch for astonishing footage -- and some blunt commentary on the realities of supercold-water swims.
