If my room was 2 degrees hotter right now, I would barely notice. So "2 degrees" by itself actually really does mean very little even to me - and I already know about the catastrophic effects that are going to come out of 2 degrees. I have to think about the sea level rise, increasing heat waves, more floods, more extreme weather, and so on for it to actually have an impact on even me.
You're right in a sense. I would certainly notice the change if it happened very quickly. However, I would quickly adapt and think it was just normal. (Mind you, my room is about 17 C at the moment.)
Certainly, if someone told me my room was going to be 2 degrees hotter permanently, I wouldn't think twice about it.

This definitely does not happen to me in these temperature ranges. 32 is too hot to function no matter how long I sit there. 30 is livable, but permanent discomfort. 28 is more or less ok, through I prefer lower temperatures.
You can feel how those differences affect your body.
