I would like point out quite opposite. Here in iran the summer has been so far one of the warmest summers anyone ever remembers. Last year was too. This year is so far hotter than last year.

I do live in very cold area in Iran. It is unbelievable how much weather has became warmer. Even i do remember when i was child , weather was noticeably colder. ( and I am in my 20's) . Let alone old peoples, who are literally ( all of them) in shock about how warm the weather became in last 5/10 years.
