Watch sand dune skiers hit the hot, dry slopes

With snowpack disappearing and desertification expanding globally, the Global Warming Riders are making the best of a bad situation and shredding some challenging dunes.

The slopes they're tackling in the clips above and below are in Peru. Note that probably the only thing harder than climbing up a snowy mountain lugging ski gear is climbing up a sandy dune. It makes a StairMaster seem like child's play, and it's usually in temperatures higher than normal body temp.
