In their comments on part one of the ‘Dual Critique’ [Vol. 7, No. 4] the authors draw attention to a number of instances where the treatment of sources and evidence is selective and biased, and perhaps where it reveals a modest understanding of the vast amount of conventional and well-established literature on climate science and allied topics. The purpose of this record is not fundamentally to dissect all the main points made by the Dual Critique authors. Rather, Simmonds and Steffen have confined themselves to commenting under a few headings on issues which they found particularly striking (grossly misleading, inconsistent with the workings of the climate system, or just plain wrong).
