Note how it is regional and dynamical, and not likely to persist. So, this is providing a source of internal variability in the climate system, where not all regions experience the same warming from the increased forcing from CO2. It is this sort of internal variability in the climate system that skeptics ignore because they want everything to be linear.
Also note that in a colder drier atmosphere, this feedback might not be so effective since cloud formation would be suppressed. Reduced cloud populations are inferred in the paleo record from the increase in dust during glacial epochs.
