"you can get a hockeystick if you waterboard this data long enough"

Kill It With Fire | Watts Up With That?

To sum up. Is the mining of “hockeystick” shaped climate reconstructions from this dataset a “robust” finding?

Not for me, not one bit. While you can get a hockeystick if you waterboard this data long enough, the result is a chimera, a false result of improper analysis. The hockeystick shaped signal is far too localized, and occurs in far too few of the clusters, to call it “robust” in any sense of the word.
