Keeping within a sufficiently small range of wavelengths that the effects discussed in 438 can be set aside, What such band widenning would do, without a surface temperature increase, is simply increase the range of wavelengths at which the same temperature variation accomplishes the same spectral fluxes through the band, thus not changing OLR
within the band — the
warming that results from such band - widenning should thus tend to increase the OLR
within the band.
If, for example, we were to create a piece-wise continuous trend
keeping your own trend, we'd find the 0.17 C decadal
