Yes, what has been said for years is that the ice cores reveal that increases in atmospheric CO2 appear after increases in temperature. In fact, this paper acknowledges that with:
Instead, just as in the ice cores, CO2 levels are found to be a lagging effect of ocean warming...
But while the ice core analysis deals with large temperature swings, and a lag of several hundred years for CO2 increase, this new paper apparently deals with recent temperature changes (which would be very slight changes by comparison) and lags of less than a year in CO2 changes. I haven't read the actual article because I don't want to pony up the $40, but that seems to be what the blog is saying.
OK, thanks for the correction. I would think the ice core data would be more significant and more definitive than any short term observations though.
