Critique 1) I have no idea about any cleansing, homogenisation or
aggregation performed on this data prior to its presentation by Rutgers 2) Snow extent is only 1 part
of the issue, thickness and mass would need to be considered for a full picture 3) I haven't taken care to provide exactly similar sample sizes, however the F and t methods do not require it 4) I haven't taken care to ensure that the same number
of winter periods are present in each sample batch; this would increase the risk
of a false positive and would have required further investigation if a weak indication
of significance had been detected.
