A MAJORITY of Republicans, Independents and Democrats believe global warming is an issue, that human activity is a significant cause and that it is a threat to future generations.

If that is what a majority of registered Republicans believe then wouldn't all of the authors points have to apply to the majority of "conservatives" as well?
I would think the difference in percentages (Democrats & Independents 12-25% more likely than Republicans to believe global warming is a threat) basically comes down to the extremes of the Sierra club types, who are likely all Democrats or Independents versus the Oil Barons who are likey all Republicans and Independents.
