Global Warmings Six Americas

The report identifies six segments of the U.S. population—the Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive—based on their views on global warming. As of September 2021, the Alarmed group is the largest segment at 33%, having nearly doubled in size over the previous five years. Conversely, the Dismissive, Doubtful, and Cautious groups have decreased in size. While 59% of Americans are now Alarmed or Concerned, the report notes that the Concerned and Cautious segments still lack a full understanding of the urgency and threat of climate impacts.

• The U.S. adult population is divided into six groups based on climate change attitudes: the Alarmed (most engaged and supportive of action), the Concerned (view it as a threat but prioritize it less), the Cautious (uncertain of causes and not very worried), the Disengaged (largely unaware), the Doubtful (doubt it is happening or human-caused), and the Dismissive (firmly reject human-caused global warming and oppose most policies).
• As of September 2021, the Alarmed segment is the largest group at 33%, outnumbering the Dismissive group (9%) by more than 3 to 1. Combined, the Alarmed and Concerned make up 59% of Americans, while the Doubtful and Dismissive make up 19%.
• There has been a significant shift in public opinion over five years: the Alarmed segment nearly doubled, increasing by 15 percentage points from 18% to 33% of the U.S. adult population. During the same period, the Dismissive group decreased from 11% to 9%.
• Despite growing support for climate action, 42% of U.S. adults (the Concerned and Cautious) do not fully grasp the urgency or the threat of climate impacts, such as extreme weather, human health impacts, and economic disasters.
