That's one reason why I'm in new Mexico.

How close to Archuleta Mesa?

I noticed that a recent conversation moved the CO2 question from driving temperatures to supporting mammalian respiration.

I have spent extended time in a few thousand ppm of CO2. Only weird side effect I noticed was communism started sounding like a good idea as Karl Marx explained it to me.

How did we get through the Medieval Warming Period without air conditioning?

When you posted this one, my memory triggered something about how controversial the MWP was, and finding my notes, I found that:
1) The MWP was discredited, and considered a failed notion, around 2005; according to PhD Mark Bowen, who had accompanied PhD Lonnie Thompson on his high-altitude ice-core missions around the globe, discovering the data which would destroy the MWP hypothesis.
2) The MWP turned out to be only a 'regional phenomena', mainly restricted to Northern Europe, the Andes Mountains, and a few other isolated regions. The rest of the planet was unaffected, with some regions actually 'cooling' at the same time.
3) The American Petroleum Institute underwrote Sallie Baliunas, Willie Soon, and others, around 2003, to champion the Steller- Radiance variability driver for the Medieval Warm Period hypothesis, in hope of deflecting attention away from the true causation for climate change.
4) The 'science' ultimately proved the fallacy of both the so-called 'Warming' itself, plus the 'bogus' mechanism responsible for its origin.

This came up last week, but has 'disappeared', as best as I can tell.
The Younger-Dryas is another phenomena which also experienced a mis-attribution within the scientific community:
1) This Heinrich event ('cold-reversal'), which occurred 11,600-years ago in the Atlantic Ocean, was originally thought to have originated from a massive freshwater pulse entering the ocean, from an ice-dam breach, from 'Lake Agassiz', which had formed over North America, from the melting of the Laurentide Ice Sheet, at the end of the last ice-age.
2) The hypothesis was that, the freshwater diluted the thermohaline heat conveyor of the Atlantic Meridional Overturning Current ( AMOC ) [ the 'Gulf Stream' ] from the Equator so much that it failed to deliver heat to the North, bringing on the 2,000-year cooling event ( The Day After Tomorrow ).
3) Again, high-altitude, mountain glacier ice-cores would reveal that the phenomena was actually driven by 'atmospheric' drivers, specifically, a draw down of atmospheric methane ( CH4 ). This IS the reason for alarm, as the melting of Arctic permafrost will play the Heinrich event in reverse, causing a rapid buildup of methane, which is 87-times more powerful as a greenhouse gas than carbon-dioxide. When the methane eventually biodegrades, it will become carbon dioxide, for a thousand years. Rapid warming!

In 1900, Earth averaged 56.58-F
2006, 57.99-F
2024, 59.00-F, Delta 2.5-F ( delta- 1.344-C )
An additional 0.656-F will take us to 2.00-C.
Turning coal-fired power plants will take us to 60.5-F ( delta-2.51-C )
The Moon's average temperature hasn't changed over the past 124-years.

Let's all go to the Moon!

The Younger Dryas impact hypothesis (YDIH) proposes that the onset of the Younger Dryas (YD) cool period at the end of the Last Glacial Period, around 12,900 years ago was the result of some kind of extraterrestrial event with specific details varying between publications. [1]: Sec 1 The hypothesis is controversial and not widely accepted by relevant experts.

But data is all we have to work with, since we weren't there to experience the Gell-Mann Amnesia effect

DuckAssist
BETA
The Gell-Mann Amnesia Effect refers to the phenomenon where individuals recognize the unreliability of media when it covers topics they are familiar with, yet still trust the same media for information on other subjects. This effect highlights how people tend to overlook inaccuracies in areas they are less knowledgeable about while being critical of inaccuracies in areas they are well-versed in.

That said, here an analysis of the 2022 Hunga Tonga event:

Is Tonga Eruption Responsible for 2023/2024 Heatwaves?

Spoiler: The largest eruption on record (2nd only to Krakatoa) being underwater releasing water vapor into the upper atmosphere and sulphur dioxide had no effect on temperature either way. And I thought vulcanism was the fast path to the big big changes.

From what I've read, the effect from volcanoes is overall a cooling effect. But some suggest that volcanoes at times have lowered the Earth's temperature by half a degree in our life times. If there were ever a major eruption, or a large enough meteorite hitting the Earth, or an all out nuclear war, the end result would be a dark global winter that would last until all the dust and other Earth cooling particles fell out off the atmosphere.

The amount of greenhouse gasses that volcanoes emit is minuscule compared to what mankind is emitting.

Yeah, but per-capita, it's infinite, so they have a lot to answer for.

Infinite volcano dwellers?
