The El Niño just raised temperatures by around 0.4 degrees C, and this has to be reflected
in the outgoing long wave radiation.
Response: Beacuse i) solar irradiance is not increasing appreciably, and ii) the bigger effect is the reduction
in outgoing long wave radiation by increasing GHG concentrations.

My contribution had its ups and downs — a low point was definitely when Judge Alsup declared «your chart sucks»
in response to a powerpoint slide (right) which showed an artist's impression of the Nimbus 4 satellite at the expense of a graph of how the spectrum of
outgoing long wave radiation changed
in response to rising greenhouse gases between 1970 and 1997.
Earth's energy balance
In response to a positive radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net energy loss to space in order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRB

This will only be balanced (
in a quasi-equilibrium way) when the surface temperature rises sufficiently to increase the
outgoing long wave radiation.
It comes down to simple physics, the fact that greenhouse gases absorb
outgoing long wave radiation and that according to the Stephan Boltzmann equation the change
in temperature is proportional to the
radiation balance.
GHGs slow the release of
Outgoing Long wave radiation («OLR»), allegedly reflected
in the energy imbalance at the top of atmosphere.
Observations suggest lower values for climate sensitivity whether we study
long - term humidity, upper tropospheric temperature trends,
outgoing long wave radiation, cloud cover changes, or the changes
in the heat content of the vast oceans.
«The Planck feedback parameter [equivalent to κ — 1] is negative (an increase
in temperature enhances the
long -
wave emission to space and thus reduces R [the Earth's
radiation budget]-RRB-, and its typical value for the earth's atmosphere, estimated from GCM calculations (Colman 2003; Soden and Held 2006), is ~ 3.2 W m2ºK — 1 (a value of ~ 3.8 W m2ºK — 1 is obtained by defining [κ — 1] simply as 4σT3, by equating the global mean
outgoing long -
wave radiation to σT4 and by assuming an emission temperature of 255 ºK).»
Such an increase is seen
in the reanalyses, and the
outgoing long -
wave radiation has become more diffuse over time, consistent with an increased influence of greenhouse gases on the vertical energy flow from the surface to the top of the atmosphere.
Then we see a headline
in a paper that reads: «Increase
in greenhouse forcing inferred from
outgoing long -
wave radiation».
