Watch These Daredevils Whitewater Kayak Greenland’s Sub-Zero Meltwater

Greenland’s massive ice sheet is slowly melting. So it made for the perfect getaway for a trio of National Geographic‘s “Adventurers of the Year.”

Watch as they kite-ski along the icy surface of the sheet and whitewater kayak in sub-zero temperatures throughout this 600-mile journey, which was shot by Red Bull.

It’ll make you shiver just looking at them. Watch it above.
