Abstract: I use one nationally representative sample from CBS News/New York Times Poll on Environment (2007), supplemented with monthly temperature and precipitation data from the United States Historical Climatology Network and extreme weather events data from National Climatic Data Center, to examine how different weather measures and individuals’ socio-demographic background, political predisposition, and beliefs about global warming affect the perception of local weather. Beliefs about global warming are found to play a dominant role in determining the perception of local weather. Specifically, people who view that global warming is causing an immediate impact, is serious, and needs to be a priority are much more likely to perceive a strange pattern of weather in the recent past. This finding conforms to motivated reasoning which refers to the tendency to interpret evidence to confirm the preexisting beliefs and predisposition. Among all the weather measures, the total number of extreme weather events in the past three years appears to be the only significant indicator of perceived weather. Specifically, individuals who have experienced more extreme weather events in their home counties are more likely than those elsewhere to perceive the weather is stranger than usual. I further examine how actual weather and perceived weather together affect perceptions of global warming. The results illustrate that the perception of local weather has stronger explanatory power than actual weather. People who perceive the strange weather patterns are much more likely than others to see the immediate impacts and priority of global warming. Future studies are needed to investigate the dynamic relationship between perceptions of global warming and perceptions of weather and climate. In addition, more studies are needed to further examine how the public forms their opinions toward various specific types of the local weather and climate.
