How Multiple Crises Impact Public Concern for Climate Change
Global reporting on climate change fell significantly from its peak in 2021, but new social research indicates that public concern has not vanished.
- Global climate coverage peaked in 2021 before declining, but communication research shows public worry remains stable rather than disappearing entirely.
- Longitudinal survey data from Matthew Sisco et al. (2023) published in Global Environmental Change reveal that COVID-19 concerns did not crowd out climate anxieties.
- Controlled survey experiments by Adrian Rinscheid and Sebastian Koos (2023) published in Communications Earth & Environment show that pandemic and war pressures do not erode support for climate policies.
Tracking Public Attention Across Multiple Crises
Researchers investigating climate communication often debate whether human minds can process more than a handful of major threats simultaneously. Matthew Sisco and colleagues examined longitudinal survey data from the United States, India, and China gathered between late 2019 and mid-2020. By tracking respondents before and during the onset of the pandemic, the study mapped shifts in public attention. The analysis also reviewed news and Twitter data to verify trends in media output, finding a clear reduction in climate coverage that matched metrics recorded by the Media and Climate Change Observatory.
Testing the Finite Pool of Worry Hypothesis
Despite dropping media volume, the data challenged the assumption that acute threats displace long-term anxieties. Sisco et al. found that worry over COVID-19 did not crowd out other anxieties such as climate change, but instead appeared to spill over and amplify general concern. Building on this framework, Adrian Rinscheid and Sebastian Koos conducted a controlled survey experiment with German respondents to determine whether war and disease outbreaks diminish backing for environmental policies.
Evaluating Public Support for Climate Measures
When Rinscheid and Koos asked German respondents to imagine worsening crises and indicate their willingness to accept higher costs or personal restrictions for climate protection, responses varied by crisis type. While potential economic deterioration from the war in Ukraine showed minimal impact on climate policy backing, pandemic-related restrictions correlated with an increased willingness to accept similar measures for environmental protection. Researchers observed that the rise in support primarily stemmed from citizens already concerned about climate change.
Strategic Planning for Environmental Communicators
Communication experts associated with the Climate Communication Lab at the University of Hamburg point out that temporary drops in media visibility are normal reflections of finite human attention spans rather than active public opposition. Forcing continuous alarm during periods of intense geopolitical or economic stress risks triggering cognitive overload, stress, or audience burnout. Practitioners instead monitor upcoming political calendars and windows of opportunity to time their outreach effectively without provoking defensive public backlash.
