The latest New York Times/Stanford University/Resources for the Future Poll on global warming is based on telephone interviews conducted Jan. 7 to 22 with 1,006 adults throughout the United States.

Resources for the Future and The Times contributed financing for the survey, and all three organizations collaborated in the questionnaire design and data analysis. Each organization is solely responsible for its own analysis and interpretation.

SSRS of Media, Pa., conducted sampling, interviewing and tabulation for the survey. Interviews were in English or Spanish.

The sample of landline telephone exchanges called was randomly selected by a computer from a complete list of more than 82,000 active residential exchanges across the country. The exchanges were chosen to ensure that each region of the country was represented in its proper proportion.
