  1. WUWT didn’t read it. Several criticism made by WUWT are answered in the supplemental data.

  2. The original, long-term study showed temperatures preceding CO2 by 800 years. The new study proposed that on a shorter time-frame, the reverse happens, CO2 goes up and then the temperature. However, the bigger comes from the smaller: the long-term is only the collective pattern of the smaller.

    It is noteworthy that this result came not from new data, but from a reanalysis and “correcting” or “adjusting” of previously studied data with other proxy data. Yet it might be true. Once more there is a ‘however’: if true, then it means that the long-term data must be out of temporal whack.

    One of them is wrong.
