While the scientific evidence for climate change is overwhelming, it has become an ideological matter. In the case of conservatives, climate change denial has become something of a stock position. In the case of liberals, belief in human-caused climate change is a standard position. Because of the way ideological commitments influence thought, those who are committed to climate change denial tend to become immune to evidence or reasons offered against their view. In fact, they tend to double-down in the face of evidence—which is a standard defense people use to protect their ideological identity. This is not to say that all conservatives deny climate change; many accept it is occurring. However, conservatives who accept the reality of climate change tend to deny that it is caused by humans.
This spectrum of beliefs does tend to match the shifting position on climate change held by influential conservatives such as Charles Koch. The initial position was a denial of climate change. This shifted to the acceptance of climate change, but a rejection of the claim that it is caused by humans. The next shift was to accept that climate change is caused by humans, but that it is either not as significant as the scientists claim or that it is not possible to solve the problem. One obvious concern about this slow shift is that it facilitates the delay of action in response to the perils of climate change. If the delay continues long enough, there really will be nothing that can be done about climate change.
