The Consensus Deception and Manufactured Agreement

Cook et al. (2013): The 97% Myth

The "97% consensus" claim originates from Cook et al. (2013), which reviewed 11,944 climate science abstracts. Only 0.3% (41 abstracts) explicitly stated that human activity (specifically CO₂ emissions) is the dominant cause of recent warming. Most abstracts made no attribution claim, yet were counted as supportive if they mentioned anthropogenic influence or climate change in general.

Scientific Agreement: What the Data Really Shows

There is broad consensus that climate is changing and that humans have some influence. However, there is no robust consensus on the degree, timing, or dominance of anthropogenic CO₂ as the primary driver, especially given natural variability, ocean-atmosphere coupling, and model uncertainty[1][3].

Bray & von Storch (2010): Model Skepticism Among Scientists

Surveys of climate scientists reveal fewer than half strongly trust model projections. Skepticism centers on cloud processes, regional precipitation, and extremes. The consensus is strongest on climate change as a phenomenon, weaker on attribution, and weakest on model predictive skill.

Confirmation Bias and Rhetorical Amplification

Consensus research is vulnerable to subjective classification, selection bias, and institutional incentives. The 97% figure is widely amplified by advocacy groups and media, while academic incentives discourage dissent and reward alignment with “settled science.”

Synthesis and Policy Implications

  • The “97% consensus” is not a robust empirical metric of agreement on CO₂-driven warming, but a rhetorical artifact[1].
  • Actual consensus is strong on climate change existence, moderate on human influence, and weak on CO₂ dominance and model skill.
  • Overconfidence in consensus narratives leads to regulatory overreach, underrepresentation of scenario diversity, and poor resilience to model failures.
Recommendations:
Abandon rhetorical consensus
Embrace scenario pluralism
Prioritize empirical validation
Protect scientific dissent
Systemic Risks:
Overconfident regulation
ESG misalignment
Erosion of trust
Suppressed innovation
