A severe heatwave is ongoing in Europe. Temperature records broken in France, Switzerland, Germany and Spain.

On 11 July 2023, the Land Surface Temperature (LST) in some areas of Extremadura (Spain) exceeded 60°C, as highlighted in this data visualisation derived from measurements from the Copernicus Sentinel-3 Sea and Land Surface Temperature Radiometer (SLSTR) instrument. The ongoing heatwave in Spain this week is resulting in a total of 13 autonomous communities, being at extreme risk (red alert), significant risk (orange alert), and risk (yellow alert) due to maximum temperatures that, in some cases, will exceed 40°C and reach a maximum of 43°C.

For reference, "in areas where vegetation is dense, the land surface temperature never rises above 35°C. The hottest land surface temperatures on Earth are in plant-free desert landscapes."

If we are starting to get alarmed over surface temps, here's my patio furniture temp right now in Arizona

Air temp is currently 43.8C

I always hate these comments, and this is a whole new level.

Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.

TL;DR: You'd probably freeze to death if the local temperature suddenly became -30C.

Above a certain temperature, acclimation consists of death. At like 130 f/95 c.

Wet bulb is a concept were gonna learn about the hard way.

*130 f is 54c. Very hot but not boiling water hot.

Yeah sloppy post on my part. This tells the story

I'm not sure if the OP edited it or not, but it sounds like you're assuming they're saying something more than they are. They never said "we're all going to die". They're just pointing out that it's also a very high surface temp in Arizona, which is nearly exactly the surface temp the title states in Spain.
