Absolutely. Wet-bulb temperature episodes are exactly the sort of thing where increasing energy in the chaotic system will lead to previously unreachable spikes in the system: by increasing the ambient energy of the system X degrees, thus increasing its chaotic energy, you produce a maximum peak excursion of X*Y degrees (also accompanied by unexpectedly COLD extremes in a more irregular pattern).

Even in the absence of other weather events these exaggerated peaks and dips are dangerous to life.
