A wet bulb thermometer measures wet bulb temperature (WBT), which exists always as long as thereâs any humidity whatsoever in the air. It only gets bad when the WBT reaches an extreme value, as is the case for basically all environmental metrics. Saying that wet bulb temperature is lethal is like saying that temperature is lethal. Look out for temperature! Iâm sorry for the rant so Iâll try to keep this short, but âwet bulbâ by itself in this context is an inane shorthand that lacks all the significant words and muddles the meaning of those words that are in it. Scientists talk about Extreme WBT events, because thatâs what they are.

The problem with your rant is that the âextremeâ label is applied by researchers in temperate climates and could very easily, and almost certainly will be thanks to Trump, be replaced by âtropicalâ

An extreme value is always only extreme in relation to some baseline. For temperatures itâs usually a value that departs far from the local average. With WBT it could mean values that approach the limit of what the human physiology can handle, a value that is quite universal due to us all being of the same species. The body cannot adapt beyond the limits set by thermodynamics.
Tropical and extreme arenât mutually exclusive. +30°C in Antarctica would be both tropical and extreme. Both are used where applicable. A temperature can also be extreme without being tropical. No matter what Trump thinks, he doesnât have the power to redefine words.
