Dunhuang, China—Is there more to China's low-carbon efforts than renewable power? Well, yes, of course. A lot more. Yet that's all people here ever seem to want to talk about. Maybe that shouldn't come as a shock: The country gets a ton of warm, fuzzy press for its enormous new wind and solar farms, and it's true that the scale of construction out deserves an impressed whistle or two.
Jiayuguan, China—My first question to the mayor, naturally, is about the porpoise. On the outskirts of Jiayuguan, an industrial city of about 300,000 smack in the middle of the Gobi Desert, there's a 15-story-tall steel dolphin, standing erect, balancing a giant ball on its nose. After dusk, the structure is set ablaze in bright neon, its flashing flippers visible from miles away. "That's not a, uh, native species around these parts, is it?" Nope.
