N.B. the 35c/95f temperature they're talking about is _not_ air temperature. It's 'wet bulb' temperature, or what the air temperature would be at 100% humidity. Only when the actual humidity is 100% are the two equivalent. Otherwise, the wet-bulb temperature measures the lowest temperature achievable by evaporative cooling. The survivability concerns of sweat being unable to cool humans below hyperthermic levels should be obvious.
At quick check, humidity in Houston is like 55%, so the wet-bulb temperature is only ~80f. Uncomfortably hot, but not close to the threshold discussed in TFA.
