I postulated on the other thread that a reason some folks don't really accept CC as a "fact" is they haven't noticed it themselves. The poll suggests most of us have, perhaps that was influenced by media reports to some extent.
The evidence suggest things have warmed by 1.1°C over the past century. I wondered if that was enough to notice without data. It seems that it is. I checked the second box myself mostly based on my recollection of winter when I was a kid.
Then the question would be how much shift would be needed for nearly everyone to agree it's getting hotter (without reading up on the "news" and evidence and figures etc.).
I'd note that it remains difficult to measure a "global mean temperature", maybe it's really impossible.
