Even the Himalayas are now vulnerable.
如今，甚至连喜马拉雅山脉都变得十分脆弱。
With most of the world's tallest peaks, and covering a third of a million square miles,

this is the greatest mountain range of all.

And here, temperatures are now rising faster than the global average.

and that is a challenge for one of the most majestic of all mountain creatures. The snow leopard.
