This special topic poll, conducted April 5-10, 2007, is part of a continuing series of monthly polls that solicit public opinion on the presidency and on a range of other political and social issues. The focus of this poll was environmental issues. Respondents were asked to rate the condition of the natural environment and to give their opinions about the biggest environmental problem the world faces today. Questions about weather patterns focused on whether the respondent thought the average temperature in the United States and in the world had increased over time, and whether they believed the earth's temperature had been increasing over the past 100 years. Respondent's opinions about global warming were collected and included information on how important global warming was to the respondent, how serious it was to them, how much could be done to reduce future global warming, how much could be done to reduce the effect of global warming on people and on the environment, and whether the federal government should do more to try to deal with global warming. Respondents of this poll were also asked a series of questions about national parks such as whether the respondent had ever visited a national park in the United States, whether the country's national parks were better compared to five years ago, whether they are well managed, and what respondents thought should have priority at national parks. Other questions asked whether respondents favored or opposed tax increases on electricity and gas, building cars that use less gas, building appliances that use less electricity, building homes and offices that use less energy for heating and cooling, and lowering the amount of greenhouse gases allowed into the air. Respondents were also asked who they trusted to do a better job, President Bush or the Congress, handling the overall environment, global warming, and the national parks. Demographic information includes respondent sex, age, race, income, marital status, religious preference, education level, type of residential area (e.g., urban or rural), political philosophy, political party affiliation, whether the respondent owed or rented their home, and whether there was any children under the age of 18 living at the respondent's home.

ICPSR created a unique sequential record identifier variable named CASEID for use with online analysis.

The data available for download are not weighted and users will need to weight the data prior to analysis.

Variables MSA, CSA, and METRODIV contain unknown codes.

Variables Q10, Q10A, and Q10FINAL contain truncated value labels.

Several codes in the variable CBSA contain diacritical marks.

The variables PCTBLACK, PCTASIAN, PCTHISP, BLOCKCNT, MSAFLAG, CSA, CBSA, METRODIV, ZIP, and NIELSMKT were converted from character to numeric.

Variables FIPS and ZIP were recoded and variable SMSKEY was removed to protect respondent confidentiality.

This survey, produced in consultation with Prof. Jon Krosnick and the Woods Institute for the Environment at Stanford University, builds on an ABC News/Time magazine/Stanford poll on global warming in 2006 (ICPSR 4658), and the 1997 and 1998 environmental polls by Krosnick at Ohio State University. The data collection was produced by Taylor Nelson Sofres of Horsham, PA. Original reports using these data may be found via the ABC News Polling Unit Web site and via the Washington Post Opinion Surveys and Polls Web site.

Households were selected by random-digit dialing. Within households, the respondent selected was the adult living in the household who last had a birthday and who was home at the time of the interview.

Persons aged 18 and over living in households with telephones in the contiguous 48 United States.

2009-05-18 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

The data contain a weight variable (WEIGHT) that should be used in analyzing the data. The data were weighted using demographic information from the Census to adjust for sampling and nonsampling deviations from population values. Respondents customarily were classified into one of 48 cells based on age, race, sex, and education. Weights were assigned so the proportion in each of these 48 cells matched the actual population proportion according to the Census Bureau's most recent Current Population Survey.
