I'm only just digesting this, but it appears that Judith Curry, climate scientist turned anti-climate change activist (more or less) has joined the Koch Brothers front group "Cause of Action".

How do we know this? Because she has filed an Amicus Brief (2017.01.25 Mot. for Leave to File, Nos. 14-cv-101 14-cv-126 (D.C.))( on behalf of the National Review and the Competitive Enterprise Institute in the case of Mann vs. Those Guys, with council at Cause of Action Institute.

Go read the brief. It is pretty nasty.

Have at it.
