The Pew Center for the People and the Press found that 66 percent support the proposed US-Canada oil pipeline project, which the environmental movement is dead-set against. That support cuts across a lot of lines, Pew notes. The poll also found support for natural gas fracking and a decline in the number of people who think global warming is a threat:

Substantial majorities of Republicans (82%) and independents (70%) favor building the Keystone XL pipeline, as do 54% of Democrats. But there is a division among Democrats: 60% of the party’s conservatives and moderates support building the pipeline, compared with just 42% of liberal Democrats.

The national survey by the Pew Research Center, conducted March 13-17 among 1,501 adults, finds that the public has mixed opinions about increased use of fracking, a drilling method that uses high-pressure water and chemicals to extract oil and natural gas from underground rock formations. About half (48%) of Americans favor the increased use of this process, while 38% are opposed.

The survey also finds that 69% say there is solid evidence that the average temperature on earth has been getting warmer over the past few decades. That is little changed from last October (67%), but up 12 points since October 2009.

At the same time, however, the percentage of Americans who say that global warming is a very serious problem has slipped six points, from 39% to 33%, since last October. Current opinions about whether global warming is a very serious problem are similar to those in 2009 and 2010.
