From the Pew Research Center:
Views about the existence and causes of global warming have changed little over the past year. A new Pew Research Center poll finds that 59% of adults say there is solid evidence that the earth’s average temperature has been getting warmer over the past few decades. In October 2009, 57% said this.
Roughly a third (34%) say that global warming is occurring mostly because of human activity, such as the burning of fossil fuels, which also is little changed from last year (36%).
The latest national survey by the Pew Research Center for the People & the Press, conducted Oct. 13-18 among 2,251 adults reached on landlines and cell phones, finds that 32% say global warming is a very serious problem while 31% think it is somewhat serious. A year ago, 35% described global warming as a very serious problem and 30% said it was somewhat serious.
In 2006, far more Americans said there was solid evidence that the average temperature has been rising over the past few decades. In July of that year, 79% believed there was evidence of global warming, and half (50%) said it was mostly caused by human activity. Much of the change in attitudes about global warming occurred between April 2008 and last fall, with the decline coming mostly, though not entirely, among Republicans and independents. (See “Fewer Americans See Solid Evidence of Global Warming,” Oct. 22, 2009).
Two other indicators of opinion on the issue were not included in the October 2009 survey, and both show significant changes from earlier polls. Currently, 46% of the public says global warming is a problem that requires immediate government action. In July 2006, 61% said the issue needed immediate action. This decline is mostly a consequence of the fact that fewer now say global warming is a problem.
The public is divided on the question of whether scientists themselves agree that the earth is warming because of human activity: 44% say scientists agree, and 44% say they do not. In July 2006, when a much higher percentage of the public said there was solid evidence of global warming, 59% said that scientists agree that global warming is caused by humans, while just 29% said scientists do not agree.
The new survey finds continuing support for a range of policies to address the nation’s energy supply, including requiring improved vehicle fuel efficiency and increasing federal funding for research on wind, solar and hydrogen technology. Support for allowing more offshore oil and gas drilling – which declined during the Gulf of Mexico oil leak – has rebounded modestly. Currently, 51% favor allowing more offshore oil and gas drilling, up from 44% in June.

Caveat: some of the usual suspects will complain that the graph I presented has “bias” due to it showing only the range of change in the data on the Y axis, and not the full possible range.
