hey, what's going on?

Have you seen the smoke in the city? have you smelt it? have you felt it? have you coughed because of it? I can go on and on.

It started more than ten days ago and at the beginning nobody realized it.

I assumed that it was a fire somewhere else, until I saw this, this and this. What on Earth is going on?
It has never been seen or suffered before. Until now, that I can't breathe normally. By the way, have I mentioned that I'm allergic to those particles floating in the air? (so is my dog and the rest of the citizens!)
