<p>Swedish researchers face an antagonistic climate of denial, scepticism, and distrust. Despite Sweden’s reputation as a climate forerunner, our interviews with 30 researchers show problems for conducting climate research in the country. Researchers use diverse communication and public engagement strategies, but often risk increasing exposure to problematic criticism and damage to their reputations. Interviewees considered themselves largely trusted, but reported attacks towards themselves and their research results. Anticipated misuse and unfounded criticism of research showed to be a decision factor for publishing. Threats and harassment have led to researchers self-censoring, avoiding media, or disengaging from public engagement. The societal implementation of research is disrupted by claims against researchers’ trustworthiness. This article suggests that researchers should be provided training, funding, and time to manage public engagement. Research institutions should take seriously the risks to their staff. Researchers should consider how different communication choices may affect their perceived trustworthiness to key audiences.</p>
