Hockey Stick and Climate Sensitivity

  1. Apr 16, 2017 #1
    I wonder if you might be able to help me with a question I have about climate change, specifically Mann's MBH99 hockey stick graph in relation to climate sensitivity equation. I would like to know where the climate sensitivity equation "Delta T = RF*lamba fits into the making of the hockey stick graph - did Mann use this equation (or some variation of it) when reconstructing paleoclimate temperatures using proxy data i.e. tree rings/ice cores/lake sediments/corals.

    I am not an expert, but at least I can refer you to what I think is a good source of information. Dr. James Powell mentions the hockey stick graph in at least one of his videos, which are available on Youtube, and he may have a more detailed explanation on his site. If not, you can contact him and request some information. I did so myself with a question and he answered fairly quickly. His Bio, which is linked to from his home page, is very impressive.
