This bit did make me uncomfortable, but it's difficult to make a complete assessment from a few lines of explanation. I wish I had time to search for peer-reviewed articles which might explain in full why the tree ring data is discarded during this period.

As for your other example, that doesn't bother me as much since their results are in agreement with those from two other organizations. There can be several paths to the same answer in science. More transparency in the methodology would be nice, however.

Thank you for taking the time to respond.
