Some of you may remember Deutche Bank's amusing attempt to address "major sceptic arguments". I posted something on this back at the start of September.
Ross McKitrick has now posted up a back and forth between himself and the authors, Mary-Elena Carr, Kate Brash, and Robert Anderson. These three were joined by a fourth author, Madeleine Rubenstein, for the subsequent responses to McKitrick. McKitrick uses the shorthand "CABR" to refer to the four, and I've adopted the same style here.
There's quite a bit of reading, but it's certainly worth investing the time. The work of the CABR team is, quite frankly, extraordinary. It is so bad I'm going to refrain from further comment.
