35% believe that human activity is causing global warming, 47% due to "planetary trends"

Rasmussen Reports has this new poll. The most interesting thing to me though is that the whole Climatagate controversy has had no detrimental effect of man-made global warming claims.

Questions continue to mount over the science behind years of studies that say humans are chiefly to blame for global warming. But reflecting a trend that has been going on for more than a year, just 35% of U.S. voters now believe global warming is caused primarily by human activity.
The latest Rasmussen Reports national telephone survey finds that 47% think long-term planetary trends are mostly to blame, down three points from the previous survey in January. Eight percent say there is some other reason, and 10% aren't sure. . . .
