Bottom line: one of the earliest members of Greenpeace (and possibly one of the founders; seems to come down to what you consider a “founder”*) later grew a brain and supported nuclear power and now doubts that human-produced CO2 is a significant cause of global warming and even that global warming is a bad thing. This inevitably led to Greenpeace rewriting his role in the past.
Meh, could be worse. Earth First! could already have
murdered been nowhere near when something bad happened to him.
* And considering the number of Greenpeace ships which have gone to their watery grave, I’m not sure being a founder is a good thing. Though being a splinter would be worse.
