The latest Rasmussen Reports national telephone survey shows that 47% of voters blame global warming on planetary trends, while 37% of voters take the opposite view and blame human activity. Just 5% point to some other reason. On just about everything concerning energy policy, there is a significant partisan divide. Sixty-one percent (61%) of Republican voters blame global warming on planetary trends, while half of Democrats (50%) blame human activity. Fifty-one percent (51%) of voters not affiliated with either party blame planetary trends. More than half of Democrats (52%) consider global warming to be very serious, compared to just 18% of Republicans and 29% of unaffiliateds. Forty-four percent (44%) of voters now see a conflict between economic growth and environmental protection, up six points over the past month. That finding is more consistent with results found earlier in the year. Only 31% do not see this conflict, but another 25% are undecided.
