Public disputes over climate science are sustained not only by arguments, but also by the networks that give those arguments visibility. With Erin B. Fitz, I examined signatories to organized climate-contrarian statements to ask who claims expertise and how those individuals connect to wider political and economic networks.
Documented organizational and industry affiliations among signatories
The expert classification refers to signatories in the study, not the percentage of scientists who reject climate science. Publication concentration is based on articles in the analyzed sample.
Beyond the abstract: the argument, study design, evidence, and limits of inference.
Young and Fitz assembled 427 unique people from selected multi-signatory climate-contrarian declarations after removing duplicate signatures. They coded available professional biographies, degrees, publication histories, age, and group or industry affiliations. The study population is public signatories on these documents—not all scientists, and not everyone who has ever expressed skepticism about climate change.
Fourteen signatories, around three percent, satisfied the paper’s threshold of at least twenty climate-related peer-reviewed articles. This small expert subset accounted for roughly sixty-five percent of relevant articles among the selected signers. The finding demonstrates why a general scientific credential and publication-active expertise in climate research must not be treated as equivalent.
The published article reports countermovement-related affiliation for 82 percent: 69 percent with listed organizations alone, 11 percent with both those organizations and relevant industries, and 2 percent with industry only. The organizations include conservative think tanks, religious groups, and organized causes that reject the consensus. Association does not automatically establish funding, motivation, or the direction of influence.
Older signatories and degree-completion patterns prompted further inquiry into formative experiences and political memory. The data do not identify what a given signatory remembers or demonstrate that those memories caused climate dissent. The later book project takes this unresolved question seriously.

The sample consists of distinct names appearing in selected public climate-contrarian documents—not a sample of the world's scientists.
| Quantity | Published value | What the denominator means |
|---|---|---|
| Unique signatories | 427 | Individuals on selected, deduplicated documents |
| Expert subset | 14 (about 3%) | Met threshold of 20 climate-related peer-reviewed articles |
| Articles attributed to expert subset | 65% | Share of relevant peer-reviewed papers among the signatories |
| Organizational or related industry ties | 82% | Documented affiliations among signatories |
The affiliation distribution is 69% with specified groups alone, 11% with groups and industry links, and 2% industry only. A documented tie is not evidence that funding caused an individual's opinion.
An advanced scientific degree outside climate research is different from a publication-active record in climate science.
It refers to this group of contrarian petition signers, not to all scientists or to climate-science consensus estimates.
Birth-year and degree-year patterns invite investigation of political memory but do not identify formative events as causes.

The analysis is confined to signatories on the documents selected and cannot describe all climate researchers. Some background information is unavailable; affiliation is not proof of motive, compensation, or causal influence.
