Query: Cosmic rays and changes in atmospheric infra-red transmission   Recent work by Aplin and Lockwood [1] was interpreted by them as showing that
there is a multiplying ratio of order 10$^{12}$ for the infra-red energy
absorbed in the ionization produced by cosmic rays in the atmosphere to the
energy content of the cosmic rays themselves. We argue here that the
interpretation of the result in terms of infra-red absorption by ionization is
incorrect and that the result is therefore most likely due to a technical
artefact
