The most efficient route toward enacting such policy, the authors argue, lies not in convincing deniers to believe in climate change but in galvanizing those who already do.

In a 2015 study published in PLOS One, Maibach and colleagues found that telling people that experts agreed on climate change increased the chances that those individuals would accept that climate change was happening, was human-caused, and presented a real threat. Extra encouraging: That strategy was also particularly influential on Republicans, though liberals might also need a nudge.

For many skeptics, Neha Thirani Bagri has written in Quartz, delineating the myriad potential harms of unmitigated climate change is not an effective strategy. Instead, it can be more productive to illustrate the potential benefits that mitigation may carry. She writes:A comprehensive study published in 2015 in Nature surveyed 6,000 people across 24 countries and found that emphasizing the shared benefits of climate change was an effective way of motivating people to take action — even if they initially identified as deniers. For example, people were more likely to take steps to mitigate climate change if they believe that it will produce economic and scientific development. Most importantly, these results were true across political ideology, age, and gender.

research has found that conservatives are more likely to support a pro-environmental agenda when presented with messages containing themes of patriotism and defending the purity of nature.

the best predictor of whether we agree with the science is simply where we fall on the political spectrum.
