the first reference, which is not their own, is cited because it references one of the authors:
One of the authors (JK) worked as an expert reviewer of IPCC AR5 report. One of his comments concerned the missing experimental evidence for the very large sensitivity presented in the report [1].
The other is this paper:
[5] G. Myhre, E. J. Highwood, K. P. Shine, and F. Stordal. New estimates of radiative forcing
due to well mixed greenhouse gases. Geophysical Research Letters, 25(14):2715–2718, 1998.
Cited for this:
The first and second term are the contributions of CO2 [5] and the low clouds, respectively.
