I briefly met Chris Hope of the Judge Business School at the Cambridge Conference last year - Chris works in climate policy if I remember correctly. He has just started following me on Twitter and sent a tweet in response to reader Andrew's guest piece on mathematical models.
He was picking up on the statement that "invariably [models] require 'tuning' to real world measurements" and responds:
Aren't climate scientists criticised for this?
This seemed a reasonable point to me.
