Those polls don't really tell us how their view of temperature changes are affecting their view of policy and climate. If 67% think that, that's basically covering the West and the East, which is the areas covered by storms and fires. But that last 33% of voters elects a disproportionate number of senators, places like KS or AR have the same number of Senators as California, even though the number of citizens is a mere fraction. I just worry that there's a disproportionate share of power and votes in the hands of individuals who don't think a jot about climate, and maybe the temperature numbers "feel" small to them.
Regardless of the exact numbers, my point is similar to the original article: people don't understand the ramifications here. Even if they intuitively know 3C is almost 2X as much as 3F, they still may not understand the article's points either.
