Data: Attitude towards global warming I'm interested in data that reveals public opinion towards global warming in the US. 

It'd be best to have a time dimension to it, but I'm interested in data from around the year 2000. Since it is quite a hot topic, I expect there to be much around this, but I couldn't find anything with scientific standards - say, anything beyond political institution X / news channel Y  asked 1000 and we are not even sure what the phrasing of the question was.

I am especially interested in data that includes an indicator for income/wealth.
There's this from Polling report showing raw survey data (question, sample data, and responses) back to 2012.

Additionally this paper by Lorenzoni and Pidgeon and this paper by Leiserowitz (both 2005) discussing said data in a more academic context. You would need to do some substantial extrapolation to get time-series out of these though.
