I've never met anyone IRL in the 25 years I've been concerned, by that I mean beyond "oh yeah, climate change".
On the other hand, I have actually met many people who say if it was really a serious issue, Government would so something about it :)
It's why i now live much nearer the south pole, as a climate refugee :). Went from Latitude S19 to S30, stayed a decade, relaised not far enough and faster then expected, now at S42.
