Against Climate McCarthyism, Part Deux

Michael Shellenberger and Ted Nordhaus continue their pushback against “Climate McCarthyism,” with a particular focus on efforts to equate unorthodox climate views with Holocaust denial, guilt-by-association, and lead Climate McCarthyite Joseph Romm.  Roger Pielke Jr. chimes in here.

I posted earlier on Shellenberger and Nordhaus’ first fusillade.

UPDATE: Ron Bailey chimes in.
