Jan P. Perlwitz: The rest appears to be simply the classical heat and kitchen problem, with which he was confronted.
I think you might be right. Unless we are informed of the exact wording of the emails and other “threats” we can’t tell. A government official who threatens to take his name off a paper is not McCarthyism; while on federal grants I have threatened to take my name off papers, and my co-authors did not suffer at all (granted, I am not in the least prominent.)
What is interesting is the degree to which Dr Bengtsson feels he has been onerously criticized for doing something that he thought was pro-social, namely engaging with people who disagreed with the majority opinion.
. And when Lennart Bengtsson decides to join a right wing group of political and ideological hacks whose purpose is to spread disinformation and lies about climate science, something that directly affects climate scientists and their research, and when the response to this public political decision and statement is massive criticisms and political decisions by other climate scientists, Judith Curry is complaining about these “attacks” and labels this “Climate McCarthyism”.
Your characterization of GWPF is fallacious. They are a self-selected group of people who, like the mostly self-selected writers for the IPCC reviews, write summaries of the science, and summaries of the limitations of the science, and proposals for public policy. They sometimes highlight the evidence that the IPCC writers choose to downweight or ignore entirely; and they are less enthusiastic about globally coordinated wealth distribution programs IPCC (and poor countries) seem to favor, and more respectful toward economic development and local solutions to pressing local problems (of the sort that socialistic governments like Cuba and Venezuela tend to disrespect.) They are not “right-wing”, “hacks”, whose “purpose” is to “spread disinformation.” That is the adolescent caricature that the critics of Bengtsson evidently subscribe to. They only look “right-wing” to people who are way left of center. To us centrists, they are somewhat “center-right.”
