Not to mention that on a global scale, extreme heat is a contributing factor to hurricanes, floods, and tornadoes
... and drought, famine, and wildfires
Wet bulb events are no joke
And yet another problem that disproportionately affects poor people, I guess
Is there a thing on this earth that does not disproportionately affects poor people. Even freakin' marginal taxation still end up sparing the richs.
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.
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
