A recent model study of some hypothetical effects of biological feedbacks of climate sensitivity to doubled CO2 came into the comments here. The paper was referenced in an article on the Register and is being misused as a revelation that the world is not going to warm so much after all.
mandas had a good go at it, identifying the assumptions and qualifications that the paper explicitly enumerated and the Register article completely ignored. I thought readers might also be interested in this video debunking from “potholer54” on youtube.
Just an aside: it is funny how worthless models are when the match the historical record beautifully and predict dramatic warming in the future but are not even on the discussion radar when they produce any excuse for downplaying the severity of our situation.
