Even though there is some disagreement as to who is responsible for climate change, it is beyond substantial scientific doubt
that climate change is a major threat for humanity in the 21st century. However, there still is doubt
among the public. Why? There is an intuitively appealing theory why this is the case: Solution aversion
. The theory attempts to explain why Republicans are much more likely to deny the reality of man-made climate change, while Democrats tend to accept it as fact. The model proposes that people deny the existence of a problem partly or primarily because they disagree with the solutions that have been proposed to solve the problem. In the case of climate change these proposed solutions would be regulations that disagree with what conservatives favor: market solutions.
