Not to mention that on a global scale, extreme heat is a contributing factor to hurricanes, floods, and tornadoes

And yet another problem that disproportionately affects poor people, I guess

Wet bulb events are no joke

In short: yes.

Even fairly far north where I live (Estonia), a summer heatwave that reached ~35 C (humid air) caused a bump on the mortality graph. Of course, it was small compared to mountain made by spring COVID, but it was visible - no other weather events give visible mortality here.

When the 2003 European heat wave hit France, excess mortality was 1600 people per day - more than both sides are suffering in the war in Ukraine.

The total per all of Europe was estimated at 70 000 people.
