As the Biden administration and governments worldwide make massive commitments to rapidly decarbonize the global economy, the persistent effort to silence climate change skeptics is intensifying—and the critics keep pushing back.

This summer the International Monetary Fund summarily canceled a presentation by John Clauser, a Nobel Prize-winning physicist who publicly disavows the existence of a climate “crisis.” The head of the nonprofit with which Clauser is affiliated, the CO2 Coalition, has said he and other members have been delisted from LinkedIn for their dissident views.

Meanwhile, a top academic journal retracted published research doubting a climate emergency after negative coverage in legacy media. The move was decried by another prominent climate dissenter, Roger Pielke Jr., as “one of the most egregious failures of scientific publishing that I have seen”—criticism muffled because the academic says he has been blocked on Twitter (now X) by reporters on the climate beat.
