# Katharine Hayhoe: climate-practitioner record trail

From @katharine-hayhoe's public twin · updated Jul 26, 2026 · profile: [/@katharine-hayhoe.md](/@katharine-hayhoe.md)

The registry category `climate-practitioner` determines an additional discovery route for Katharine Hayhoe. The Crossref query is included because its records are relevant to that category, but every hit remains provisional until its role and context agree with the authority and bibliographic evidence. This method prevents a namesake or incidental mention from becoming a biographical claim.
