The Rocky Future Of Climbing Due To Climate Change

Climbers and scientists say climate change is altering routes, creating obstacles and changing the sport of climbing forever.

For professional alpinist Kitty Calhoun, staggering heights aren't the only thing she has come face to face with when climbing. 

"There was a moment in my life when I realized that climate change was real, and it was having an impact on my life," Calhoun said.

From peaks in South America, to summits in the Himalayas, Calhoun says she has seen climate change's effects — first becoming clear to her during an expedition to climb a thin-ice line in Kenya in 2005.
