Climate change and the politics of knowledge

As might be expected, people’s views about whether there is scientific understanding about climate change tie more closely to their science knowledge and education levels. For example, people who know more about science also tend to perceive strong consensus among climate scientists that human activity is responsible for climate change. However, only Democrats, not Republicans, hold beliefs about scientific consensus which vary with their level of science knowledge. Democrats holding medium or high levels of knowledge are more inclined to perceive strong consensus among climate scientists than are those with low science knowledge levels. A similar pattern occurs in public views about scientific understanding. People’s beliefs about how well climate scientists understand whether climate change is occurring and the causes of climate change are significantly linked with science knowledge among Democrats. But there is no difference among Republicans with high, medium or low levels of science knowledge in their perceptions of climate scientists’ understanding of whether climate change is occurring or scientists’ understanding of the causes of climate change. Similarly, there is a tendency for people with more science knowledge to expect harms to the Earth’s ecosystem to occur because of climate change, but this pattern occurs only among Democrats.
