Limit was hit in 2023: https://www.washingtonpost.com/climate-environment/2024/02/0...
For example, at least 24500 people died from heat-related causes in Europe during heat waves of summer 2022.
And that's just one of many examples.
Highest ambient temperature ever recorded was in Death Valley in 1913.
In 1540 Europe had an extreme drought and heatwave that lasted 11 months.
I can go on and on. The 2022 heatwave wasn’t any more unusual than any other heat wave throughout history.
You can't think of one pertinent home gadget that was invented between 1911 and now?
the Year 2023 was the Hottest Year on Record to date globally.. each month of 2023 (edit maybe not jan-feb?) was also the hottest recorded globally. The hottest day cumulatively across the world was in 2023. The nine hottest years on record globally were the last nine years.

Actually, I think January and February failed to breach the record--the El Nino didn't set up until April.
(But several of the later months absolutely shattered records, as did the year as a whole. 2023 as a whole breached the 2C limit).
I posted about it before:

We've had one year at the level of warming that is not yet expected to yield mass death from wet bulb events.
Give it time. There's no reason to think that the current warming trend will slow, stop, or reverse itself in the near term.
Climate has changed repeatedly throughout history. Every time a temperature increase has changed to a temperature decrease, this must be preceded by the rate of temperature increase decreasing.
We observe the rate of temperature increase, continuing to increase.
Thus there is reason to believe that it will get hotter for some time, before it again gets colder.
Eh, causing it is in fact a much, much bigger industry.
These are the kind of people that had to cheat off you to pass biology yet insist that "the immune system works like this"
Because we haven't seen very many 35℃ wet bulb temperature breaches yet. The nominal air temperature is much higher than that all the time around the world, but it's only when there is very high humidity at that temp that humans start to overheat.
IIRC there have only been a few instances so far where the web bulb temp limit has been breached, e.g. some instances around the Persian Gulf, and maybe also in Mexico near the Gulf of California (not sure about the latter if it's even been breached yet, but I know it's at risk).
Edit: Wikipedia page has a list, https://en.wikipedia.org/wiki/Wet-bulb_temperature#Highest_r.... There have only been 10 recorded instances where wet bulb temp exceeded 35C.
We'd be in serious trouble if we had a power failure triggered by a heat wave, which IIRC was a near miss in the central US heat wave last summer.
Wet-bulb temperature is the minimum temperature you can reach by evaporative cooling (i.e., sweating). When wet-bulb temperature gets too close to core body temperature, you are physically incapable of shedding heat if you are not in air-conditioning, and how close it needs to be depends on how good health you are in.
But we actually have seen deaths in previous heat waves, which largely didn't even breach 30C wet-bulb. The 2003 European heat wave caused about 70,000 people to die, for example.
