As Our Valiant Host says, the truth is really in the name. "New Scientist" indeed.
Just for the record, McIntyre and McKitrick cannot be "disproved" by new temperature reconstructions, because they WERE NOT OFFERING AN ALTERNATIVE RECONSTRUCTION to the Mann et al Hockeystick, as they have stated time and time again. They're not experts on climate, and acknowledge their limitations.
Instead, the two Canadians were criticising Mann's METHOD of achieving the Hockeystick graph, showing, among other things, that the statistical method used ALWAYS produces Hockeystick shapes, even when fed with random data (called "Monte Carlo test").

This "talking point" the warming enthusiasts accelerated away from as fast as they possibly could, and for good reason.
