We thought it was about “science,” Michael Mann.
From the Climategate 2.0 collection, Michael Mann confesses that climate alarmism is a ’cause':
I gave up on Judith Curry a while ago. I don’t know what she think’s she’s doing, but its not helping the cause.
Curry was Richard Muller’s co-author on the BEST study. She outed Muller as exaggerating their findings and accelerated the demise of Muller’s credibility.
Note that Michael Mann’s RealClimate.org web site has the tag line,
Climate Science from Climate Scientists
That should be replaced by:
Junk Science from Junk Scientists
