Since the oceans are massive heat sinks, they cause delays (around a decade or more) in observed temperature changes from changes in radiated energy from the sun. (realclimate.org)
In addition, the LIGO and Virgo teams were able to use the frequency of the observed wave, along with its rate of acceleration, to estimate the masses of the two black holes: because heavier objects radiate energy in the form of gravitational waves at a faster rate than do lighter objects, their pitch rises more quickly.

With regard to LC effect on surface temperature, I would think that to the extent that there's any validity in the «climate sensitivity» approach — that is to say, that a change in average surface temperature can be said to cause a proportional increase in radiated energy at TOA — it should be possible to adjust the standard formula to allow for such an effect.
