Climate skepticism encompasses the range of doubts, reservations, and misconceptions people hold about climate change science, its human causes, the severity of climate risks, and the efficacy of proposed solutions. It exists on a spectrum from full rejection of the scientific consensus on anthropogenic climate change to more nuanced concerns about economic feasibility, personal responsibility, or the relative priority of climate policy compared to other concerns.
Mechanisms and manifestations
Research identifies several categories of climate skepticism and inaction:
- Science-based skepticism: Doubt in the reality of climate change or human causation
- Policy skepticism: Acceptance of climate science but concern about the efficacy or economic viability of proposed solutions
- Personal responsibility skepticism: Belief that climate change is happening but that individual actions are insufficient or too costly
- Economic and lifestyle concerns: Aversion to climate policies perceived as economically burdensome or lifestyle-disrupting
Climate skepticism is not monolithic—individuals often hold multiple, sometimes conflicting reservations simultaneously. Addressing skepticism and inaction thus requires understanding people's specific reservations rather than deploying one-size-fits-all messaging.
Interventions and evidence
Czarnek et al. (2026) — Demonstrates that AI-driven personalized dialogues addressing individuals' specific climate change reservations substantially reduce belief in those reservations and increase willingness to take climate action, particularly donations and policy support. LLM-driven dialogue outperformed consensus messaging, even among Republicans.

Farrell (2016) — Documents the role of corporate and conservative funding in supporting climate skepticism movements and denial campaigns.
