I haven't seen these claims but two points seem like to be relevent: I listened to Nicholas talk at London School of Economics and two key points came out of that for me; firstly, the range 5-20% as i understand it, exists largely due to different scientific considerations...there is increasing concern about positive feedbacks in the climate system, this cutting edge science tends to lead to the 20% figure, the higher figure therefore seems to me not just one part of the range, but the part of the range that accurately reflects the entire scientific thinking. Also, he pointed out that at the upper end of the temperature range, the models he used where most likely not up to the job, and that long terms assumptions (beyond 2100) where probably to rosy for the upper end scenarios.
