Arguments Condensed:


"Since ~1945 when CO2 emissions accelerated, Earth experienced ~22 years of warming, and ~40 years of either cooling or absence of warming"

"In fact, strong evidence exists that disproves the IPCC's scientific position. The attached Excel spreadsheet ("CO2 vs T") shows that variations in atmospheric CO2 concentration lag (occur after) variations in Earth's Surface Temperature by ~9 months (Figures 2, 3 and 4). "

  1. This seems to make a novel claim: he evidently picked up the "CO2 lags warming, and therefore can never cause it" from the discussion of ice core records of the onset of deglaciations, and now claims it also applies to direct measurements taken today. Minor catch: the "lag" claimed for deglaciation onsets was on the order of 500 to 800 years, but the correlation he's trying to demonstrate here has a time constant some three orders of magnitude smaller.
    So in one way this could fit into a broader category of "CO2 lags temperature" but it's definitely a new twist I hadn't seen before.
