Climate change. Those two simple words have the power to bring about a strong reaction in people. For many, the term is fraught with emotion—with worry, anger, and fear of the unknown. For others, these two words might elicit doubt or frustration. According to a multi-year, nationwide study conducted by George Mason and Yale Universities, as a country we react to the science of climate change along a spectrum of responses. On one end of the spectrum, people are “alarmed” (see a change in climate as a reality and taking action about it) and “concerned” (believe it is a serious issue but have not taken action). In the middle are those in different stages of understanding or awareness of climate issues, and characterized as “cautious”, “disengaged”, or “doubtful.” At the opposite end of the spectrum are the “dismissive”, which are that group of people who are actively opposed to action on climate change and may feel it is a conspiracy. These six categories were based on the responses of a large, in-depth survey conducted in 2008. Ten years later, researchers conducted the study again to see if attitudes had changed. Interestingly, they had—with the most noticeable shift out of the “disengaged” category, as people seemed to cast their lot with one side or the other.
| 2008/2009 | Yale/George Mason Study Results | 2018 |
| 18% | Alarmed (+3) | 21% |
| 33% | Concerned (-3) | 30% |
| 19% | Cautious (+2) | 21% |
| 12% | Disengaged (-5) | 7% |
| 11% | Doubtful (+1) | 12% |
| 7% | Dismissive (+2) | 9% |

Looking at the data, respondents left the “disengaged” group and moved either towards doubtful and dismissive or towards the cautious category. It is likely that the 3% change out of “concerned” moved directly into “alarmed”, as extreme weather events and record temperatures over the last 10 years brought the impacts of a changing climate closer to home.

When the study is broken down by region, a minority of northwest Floridians believed human activities such as carbon emissions caused climate change. However ~65% of the same group believed climate change was happening (regardless of cause), and 80% responded that our country should fund research looking into renewable energy. The good news here is that while many of us do not agree on the cause of climate change, the majority of us agree on positive steps forward that may relieve some of its results.
For me, the take-home message of this study is that scientific understanding—on many issues, not just climate—is often along a spectrum based on exposure to research, personal interest/relevance, and cultural influences. When explaining any science-based concepts, it is important to know where your listener is coming from and start from there. It is unfortunate that we are in a time when many principles of science are taken as political positions and not products of unbiased scientific method. That being said, great thinkers from Galileo to Hawking have had their run-ins with popular opinion.
As the summer heat cooks on and hurricane season warms up, there will be more articles in the news about climate and its effects. When reading these, look at the source and their intent. Is this an opinion piece/blog with deeply emotional photos and stories meant to sway readers one way or the other? Or is it an agency page, reporting factual data? Time-tested agencies like the National Weather Service (NWS), National Oceanic and Atmospheric Administration (NOAA) and National Aeronautic and Space Administration (NASA) have been keeping historic records of climate data and satellite imagery of ice cover for decades. Use their information to inform yourself, no matter where you might fall upon the “six Americas” spectrum. Worldwide data for climate has been kept since 1880, and both NASA and NOAA climate data found:
- 2016 was the hottest year globally on record
- 2nd and 3rd hottest years on record were 2015 and 2014.
- 16 of the 17 warmest years documented since 1880 have been since 2001
