The Washington Post and Stanford University recently published a poll on American attitudes toward global warming and the environment (pdf). Not surprisingly, almost three quarters of Americans accept recent global warming, but only 30% think that it is human caused, while 22% think that it is naturally caused, while 47% think it is equally human and naturally caused. This is relatively unchanged over the past six years of polling
Asked if the world’s temperature is probably been going up over the past 100 years, 73% of respondents said yes, 25% of respondents said no, and 2% indicated that they didn’t know or refused to answer.
Asked “How much do you trust the things that scientists say about global warming?” 6% of respondents responded “completely,” 22% “a lot,” 33% “a moderate amount,” 26% “little,” 11% “not at all,” and 1% indicated that they didn’t know or refused to answer.
Interestingly, only 18% of Americans think that global warming is the most important environmental issue facing the world at this time. Pollution (which of course leads to global warming) was considered to be the largest issue, but numerous other problems including toxins in the environment, habitat loss, and other issues were also mentioned.
