A recent X thread by UK MP Andrew Bridgen compiles quotes from 16 scientists who previously worked with or contributed to IPCC reports. The statements accuse the IPCC of:
deliberately downplaying uncertainties
excluding or minimizing solar/climate natural variability
politicizing the process and suppressing dissenting views
producing misleading press summaries that diverge from the underlying science
cherry-picking data on sea-level rise, extreme weather trends, and model performance
Among the named scientists are several well-known figures in climate skeptic circles (Judith Curry, John Christy, Richard Lindzen, Richard Tol, Nils-Axel Mörner, etc.).The post has attracted significant engagement in certain political/climate-skeptic communities and is being used to question the IPCC's scientific integrity and the legitimacy of its policy-relevant conclusions.
