Is the slight, but measurable, increase in global warming a consequence of extraterrestrial interference to decrease the sun’s useful lifespan?

This, in fact, is the case and was hinted at in prior answers about solar activity. So while we have not made this at all clear at times, it was because you were not thinking about solar activity per se and have not asked us directly, in fact, about whether solar output has increased, but only whether the overall planet and its temperature cycles is due to anthropogenic global warming, which is the leading hypothesis proposed by those wanting to fight this problem with dollars taken from others for the purpose. So in actuality, this slight warming of a degree or so over the past century, is in fact a consequence of the changes in the workings of the sun, instigated by the Extraterrestrial Alliance. This acceleration of solar aging is, in fact, causing a slight but perceptible increase in solar output that has not been predicted to occur because of so many years of seeing relative stability in the solar radiation, with the exception of the various solar storm events like sunspot activity, solar flares, and so on, which are observed and not considered part of the discussion. The fact that you are in an interglacial period with Earth at the present time is also consistent with temperature fluctuations across large spans of time. So this little increase over the past decades particularly, is an added influence as a consequence of the extraterrestrial manipulation, and that is why there is an uptick in global temperature averages. It is correlated with fossil fuel consumption, but it is not the cause. It is indeed the solar output that has changed this and has been masked and suppressed through mind control manipulation. This is why you remember that report you saw from the Max Planck Institute some years back, talking about how the polar ice caps were receding on Mars because of an increase in solar energy. And so this global warming on our sister planet could not possibly be due to fossil fuel consumption because it is an uninhabited world, and so points the finger directly at the sun itself as the culprit for that world, and leaves open the question about whether this is true for Earth. This is why you remembered it, because you knew intuitively, that it was true for Earth as well, and this was a kind of independent corroboration of that plausibility.
