Pew Research Center for People and the Press:

About one-in-five Americans (19%) have heard a lot about the international meeting to discuss climate change in Copenhagen that is now underway. About as many (17%) say they have heard a lot about the disclosure of private emails between prominent climate scientists regarding global warming data. Fewer have heard a lot about the White House job summit that took place a week ago (11%) or about Comcast’s plan to buy NBC Universal (11%).

There is virtually no difference in awareness of the Copenhagen climate-change meeting by party. About six-in-ten Republicans, Democrats and independents have heard at least a little about the gathering; that includes 20% of Republicans, 19% of Democrats and 18% of independents who have heard a lot about it.

Republicans, however, are more likely to have heard about the climate-related email controversy: 23% have heard a lot about this, compared with 11% of Democrats. Among independents, 17% have heard a lot.
