Dear Larry, I am pointing out that even a peer reviewed article *concerning* peer reviewed articles can contain erroneous data and conclusions.
One study, especially one which so strongly refutes practical experience, intuition, and previous research and which covers such a limited time frame, cannot be allowed to stand on its own. (Or two or three, in the case of clones and Korean nationalist interests).
Wait a month or so, watch for corrections, as in the case of the Oreskes article and the buzz in the appropriate professional circles.
There are better examples in support of your thesis. No evidence current at the time definitively supported Copernicus. Eddington supposedly provided proof of Relativity in 1922. It was later shown that he didn't, that the margin of error overwhelmed his data. And Einstein went to his death dissatisfied with quantum theory which has since been shown to be the best theory humanity's ever come up with (even though it's still not really understood by anyone).
So, yes, the results are provisional.
