Key point of discussion was the unique speed of the current warming as well as the regional spread of the so-called Medieval Warm Period. McIntyre presented in a later publication, the meaningfulness of a total global average temperature in question.

After controversy, in which man refused to disclose the underlying data and presented the basic scientific suitability of the critic in question, McIntyre's criticism was internationally known and partially recognized. Man also pointed out that many of its uncertainties and possible methodological inaccuracies in its original study were addressed what had fallen in the adoption of the chart in other studies under the table. In the controversy surrounding global warming, until now the question of the accuracy and significance of this work is discussed, while the hockey stick graph in the scientific discussion of climate change plays only a minor role.
