Leiserowitz is a widely recognized expert on American and international public opinion on global warming, including public perception of climate change risks, support and opposition for climate policies, and willingness to make individual behavioral change. He has published over 100 scientific articles and book chapters on climate change beliefs, perceptions and behaviorsand often appears on popular talk shows such as Bill Moyersand Real Time with Bill Maher. Leiserowitz is a geographer trained in the cognitive and social psychology of risk perception and decision making. His 2003 PhD dissertation 'Global Warming in the American Mind' has been widely influential. Members of his PhD committeeincluded, among others, Paul Slovic, who is often considered alongside Daniel Kahneman and Amos Tversky, as the founding father of research on human judgment, risk perception, and decision making.

Together with Edward Maibach, Leiserowitz is perhaps most widely recognized for his research on the 'Six Americas', which segments the US population into 6 distinct categories based on the public's attitudes and beliefs toward global warming. The six segments include "the Alarmed" (18%), "the Concerned" (33%), "the Cautious" (19%), "the Disengaged" (12%), the "Doubtful" (11%) and the "Dismissive" (7%). Leiserowitz also recently conducted the first empirical assessment of worldwide public attitudes toward global sustainability.
