《自然-通讯》发表的一项研究Discrepancy in scientific ity and media visibility of climate change scientists and contrarians通过分析2000-2016年期间数字媒体和纸质媒体的报道后发现，与支持气候变化有人为来源这一共识的科学家相比，一群气候变化异见者在媒体报道中的出现频率要高49%。不过，如果只比较两个群体在主流媒体中的能见度，差异则降至1%。
摘要：We juxtapose 386 prominent contrarians with 386 expert scientists by tracking their digital footprints across ∼200,000 research publications and ∼100,000 English-language digital and print media articles on climate change. Projecting these individuals across the same backdrop facilitates quantifying disparities in media visibility and scientific ity, and identifying organization patterns within their association networks. Here we show via direct comparison that contrarians are featured in 49% more media articles than scientists. Yet when comparing visibility in mainstream media sources only, we observe just a 1% excess visibility, which objectively demonstrates the crowding out of professional mainstream sources by the proliferation of new media sources, many of which contribute to the production and consumption of climate change disinformation at scale. These results demonstrate why climate scientists should increasingly exert their ity in scientific and public discourse, and why professional journalists and editors should adjust the disproportionate attention given to contrarians.
