Nothing legitimate comes from SA anymore. The planet experiences periods of high temperatures and high humidity all the time, especially in equatorial areas, and has for million of years. Manipulating data and making up new pseudoscience terms such as “wet bulb” is not proof of anything.

"The wet-bulb temperature (WBT) is a temperature that can be measured by a thermometer covered in cloth which has been soaked in water at ambient temperature (a wet-bulb thermometer) and over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.
A sling psychrometer. The sock is wet with distilled water and whirled around for a minute or more before taking the readings.
The wet-bulb temperature is defined as the temperature of a parcel of air cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat supplied by the parcel.[2] A wet-bulb thermometer indicates a temperature close to the true (thermodynamic) wet-bulb temperature. The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only.
Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32 °C (90 °F), equivalent to a heat index of 55 °C (131 °F). A reading of 35 °C (95 °F) – equivalent to a heat index of 71 °C (160 °F) – is considered the theoretical human survivability limit for up to six hours of exposure."
Thanks for that Philip. A heap of muslims dropped dead this year during Mecca and it wasn't even particularly humid. One of the great tragedies of science is the slaying of a beautiful hypothesis by the discovery of the odd ugly fact. Are there any combinations of temperature and humidity that humans cannot survive for longer than six hours? If so, what are they and, if "wet bulb" is not a useful way to measure temperature and humidity combinations, how should they be measured?
