Realty czar leads fight

COPENHAGEN: Unlike most of us who try to understand climate change issues through the media, Wang Shi looks for traces of global warming when climbing the world's highest peaks.

From 1997 until now, Wang, a mountain climbing enthusiast and the head of one of the most well known real estate developers in China, has made it to the top of the world's highest peak, Mount Everest, seven times.

He said he could clearly see that the snowline was receding each time he went back up there.
