Air pollution or Weather problem??

---

Here with pics that I took in the evening of 21th Feb. 2012. When I was in the flight from Kunming to Shenzhen. The sky looks very dirty after taking off a few minutes.

Is it air pollution or just weather problem?？？ It looks serious if it’s air pollution. The atmosphere looks poisoning by brown wasters.

We have lots of problems of environments those years. And weather is not as regular as before.

Those pics are without any photoshop processing. I took with my Canon 550D+ 17-85 scene.

Hope it’s just normal weather problem,

What consequences will be if it’s real air pollution?
