Chemical/gas leaks, birds/animals dying etc...Lets put together the facts!

I've read a lot about all these recent events that have been happening recently, but most threads that have concentrated on them so far are full of chit chat or confusion or end of the world type warnings. The only way we can gain a clear understanding on what is going on is to put together all the facts and events!
So if you have any recent articles as to what has happened or is happening, post them here- i want t keep the general chit chat down on this thread until we have put together all the facts and events.
