And while by eye I could conjecture 86 % of the one year CO2 rise were temperature - correlated in any yearly cycle, clearly there is much greater temperature variability in the region of Mauna Loa in a year (~ 5 - 10C) than there has been globally since observations started (~ 0.7 C), so one would only consider Dr. Spencer's claims plausible if the rise in CO2 since 1960 were smaller than the change in a single year by a factor of ten, rather than larger by an order of magnitude.

Here, we report unique observations on atmospheric aerosol formation based on measurements at the SMEAR II station, Finland, over a solar cycle (years 1996 — 2008) that shed new light on these presumed relationships.
