The climate change debate might be one of the worst cases of academic suppression in history. CLINTEL (the Climate Intelligence Foundation) has issued the Magna Carta Universitatum 2020. This short document is basically an aspirational code of conduct for freedom of inquiry and speech at universities. The first Magna Carta Universitatum was issued in 1988 and to date at least 889 universities have signed on to it. CLINTEL notes that it is building directly on this precedent, to fit “the special challenges of today”. For each of the five principles enunciated, CLINTEL cites a climate example.
