Ok, I don't just think it's getting hotter. I confirm it's getting hotter. There are more bush fires nowadays (bush fires? Really?); leftover food on the table is rotting faster than normal; and the most significant issue at hand is I'm sweltering like a pig at night more often than not.
I'm not sure if there's a link, but do you notice the presence of more biggie butterflies than usual? Some eco-system thingy, perhaps?
