I do not know it is a hoax or not. Some say it is a hoax and some say it is science. However, we (nepali) are taught from our childhood that  global warming is real. We never tried becoming critical about any thing. We just say like " Scientists say that, so it is real". "Man reached to the moon" we repeat multiple times. But we never learned to be critical about things.We were never taught to raise  questions like "  Did man really reach the moon?", or Is global warming man made?

I think Nepali people  fully believe that global warming is man made, man reached moon and so on because  main stream media are saying that.
