> there can be significant local extremes that are far greater

You're moving goal posts. Either we're talking about global climate change, or we're talking about local changes. Local changes have always happened, and animals either adapt or die when they do. There is no argument that the global average change is any more than 1.1c in the last century.

Both are important. People who go "a couple degrees average isn't that big of a deal" are missing a big part of the dangers of global climate change.

Humans can't survive more than a few hours at a wet bulb temperature (https://en.wikipedia.org/wiki/Wet-bulb_temperature) of 35°C, even if they have shade, drinking water, and fans available. If air conditioning fails, you're dead.

As the global average creeps up, some of these local variations in hot, humid places without sufficient power infrastructure to reliably run A/C for everyone like Bangladesh have the potential to kill millions.

1.1 C = around 39 F

The world temp has gone up 39 degrees? That is much higher than I thought.

That couldn't be right?

I'm tired today.

That's not how it works.

A rise of 1.1 degrees C corresponds to a rise of 1.98 degrees F.

You have read the scale¹ instead of interpreting the value as a delta, a step, a degree. ¹(1.1°C above freezing reread in °F - 39°F - which means "the difference between a temperature almost never reached in Denmark and freezing water, plus 1.1°C".)

The Celsius scale uses 0 for "freezing water" and 100 for "boiling water".

Fahrenheit uses 32 for "freezing water" and 100 for "body temperature". (The "32" comes from interpolating Rømer's scale, and 0 is somehow "the minimum temperature ever one expected in Denmark".)

The single degree (step) is halfish/doublish that of the other scale: C = (5/9)F (from freeze to body temperature it's ~37 steps in °C and ~68 in °F). And there is an offset of 32.

It burned to the ground due to a wildfire caused by sparks from a train, not from the heat. https://en.wikipedia.org/wiki/Lytton_wildfire

Wildfires don’t spread much better in 90F vs 121F. The big thing that causes uncontrollable spreads is lots of fast wind.

> Wildfires don’t spread much better in 90F vs 121F.

That's missing the point a bit. That said, vegetation sure does get dry fast in a 120 degree heat wave, though.

Yes they do, when higher temps have dried out the vegetation.

Lack of humidity dries out vegetation more than heat.

Literally in the first paragraph of what you shared:
