E.g. If you seriously believe that the skeptic claim about temperatures this decade $$-$$ i.e. "they have been flat" $$-$$ was not meant to convey any deeper message about future climate trends, do you then think that this observation is of any real use in of itself? Of course, if you think that it does say something important about long-term climate trends, which is the only thing that really matters in this debate, then you are back to the Nordhaus' response.
