Well, actually it can. It's been raining the whole day. No breaks, just constant rain. I guess it's fall now. In August!
The summer was sucky anyway. We had warm days (meaning above +23 centigrade) for less than two weeks since May 1st until today. My flowers at the balcony froze in June! How creepy is that?!
If this is greenhouse effect, this greenhouse has its windows broken.
