Let's hope that is not surpassed.

The greatest source of human suffering is other humans - by far more direct means than the changing climate.

Yup, that is unquestionably the case.

 

[TugboatEng]

Maybe we should be warming the planet instead of trying to cool it? 10x mortality from cold climates vs hot.

It has been estimated that about 5.1 million excess deaths per year are associated with non-optimal temperatures. Of those, 4.6 million are associated with colder than optimum temperatures, and 0.5 million are associated with hotter than optimum temperatures.

https://thebreakthrough.org/issues/...d that,with hotter than optimum temperatures.

 

[dik]

Ya tug, even in Texas... when the wetbulb hits 35, watch the poeple drop like flies... it's not more heat we need!

The other side of the picture is that because of humans allegedly causing the climate change, we need less humans.

 

[BridgeSmith]

I think you've hit on the ultimate goal for some of the elites at the forefront of the movement, hokie.

 

[Tomfh]

It has been estimated that about 5.1 million excess deaths per year are associated with non-optimal temperatures. Of those, 4.6 million are associated with colder than optimum temperatures, and 0.5 million are associated with hotter than optimum temperatures.

According to climate experts the benefits of climate change don’t count.

 

[TugboatEng]

I don't understand your comment, dik. People can be harmed by temperature extremes but overall, warmer temperature extremes are less harmful.

Deaths associated with non-optimal temperatures have been decreasing over time as it has gotten warmer partly due to a reduction in cold deaths. It has been estimated that warming from 2000 to 2019 has resulted in a net decline in excess deaths globally (a larger decrease in cold deaths than an increase in heat deaths).

 

[dik]

Take a gander at climate change... some people are predicting 35C wetbulb in the not too distant future.

[hokie66]

We have that every summer here in Brisbane. And most people have no air conditioning. It's a matter of adaptation.

 

[CWB1]

Yup. In the Middle East I worked all day in the sun at 140F+, you drink plenty of water but your body adapts nicely otherwise.

The other side of the picture is that because of humans allegedly causing the climate change, we need less humans.

I'm waiting to see if politicians or AI pursue population control first. Its more than pollution, its the root cause of resource/energy scarcity and has a big impact on standard of living. It may be abhorrent to folks' morals but seems to be an inevitability.

 

[dik]

...maybe drybulb temperatures.

[hokie66]

35C wetbulb at 70% relative humidity is about 40C drybulb, 104F. Not often experienced close to the coast in Australia, but common inland. Folks do adapt. Sure, their activities are restricted, but life goes on. The worst hot weather I have experienced was in the summer of 1966, when I was in officer basic training at Indiantown Gap, Pennsylvania. 115F for about 6 days in a row, and we were undergoing a lot of PT.

 

[dik]

Catch...

"A wet-bulb temperature of 35C has been theorized to be the limit to human adaptability to extreme heat, a growing concern in the face of continued and predicted accelerated climate change. Although this theorized threshold is based in physiological principles, it has not been tested using empirical data. This study examined the critical wet-bulb temperature (Twb, crit) at which heat stress becomes un-compensable in young, healthy adults performing tasks at modest metabolic rates mimicking basic activities of daily life. Across six experimentally determined environmental limits, no subject’s Twb, crit reached the 35C limit and all means were significantly lower than the theoretical 35C threshold. Mean Twb, crit values were relatively constant across 36C–40C humid environments and averaged 30.55 ± 0.98C but progressively decreased (higher deviation from 35C) in hotter, dry ambient environments. Twb, critwas significantly associated with mean skin temperature (and a faster warming rate of the skin) due to larger increases in dry heat gain in the hot-dry environments. As sweat rates did not significantly differ among experimental environments, evaporative cooling was outpaced by dry heat gain in hot-dry conditions, causing larger deviations from the theoretical 35C adaptability threshold. In summary, a wet-bulb temperature threshold cannot be applied to human adaptability across all climatic conditions and where appropriate (high humidity), that threshold is well below 35C."

and from

"A wet-bulb temperature of 35 °C, or around 95 °F, is pretty much the absolute limit of human tolerance, says Zach Schlader, a physiologist at Indiana University Bloomington. Above that, your body won’t be able to lose heat to the environment efficiently enough to maintain its core temperature. That doesn’t mean the heat will kill you right away, but if you can’t cool down quickly, brain and organ damage will start."

[Tomfh]

More of the earth is inhospitable due to cold than due to heat. An increase of several degrees will in total increase the habitable zone.

 

[dik]

I agree, Tom... Winnipeg will likely benefit (subject to drought conditions), but at the expense of other areas.

[hokie66]

Those physiologists know not of what they speak. May be difficult for a Canadian to understand, but it just ain't so.

Wet bulb is not the only criteria for inhospitable conditions. At 100% humidity, wet bulb and dry bulb coincide.

 

[TugboatEng]

I agree, Tom... Winnipeg will likely benefit (subject to drought conditions), but at the expense of other areas.

Why drought conditions? Drought stricken California just experienced its wettest year in very recent history (climatologists don't like to look at that year before 1863). Less biased climate studies have indicated more precipitation with warming.

Remember that Earth supported the creation of life under much higher temperatures. Creatures with much less evolution were able to adapt and thrive. Dinosaurs likely went extinct due to cooling, not warming. Perhaps we should embrace this next stage of life.

 

[dik]

Missed that tug, subject to drought 'or maybe storms', Winnipeg will likely have nicer weather. With climate change either is a possibility. There will also be places on earth that remain the same as they were. In addition to it being warmer it could also be wetter and/or drier. We don't know what, if anything, will change.

Prior to 1863, and even later, the data may be a little sketchy... but they have charted the CO₂ back a lot earlier and their data is pretty conclusive... CO₂ is going up and is higher than it has been for a couple of million years. They also have a pretty good idea of the effect of CO₂.

Earlier life was cold blooded, too, not warm blooded, and changes occurred over millennia, not decades. Things may be a little different, this time.

Hokie... being warm blooded creatures, we have to regulate our body temperatures. If your organs slowly break down due to overheating there could be serious long term issues. Sustained temperature may be 'for a long time' and not just a few days or a couple of weeks. With temperatures of 40C, and air that is not water saturated, there is evaporation, ie. cooling.

The Middle East and Africa (and occasionally Australia) experience high temperatures, but not with extreme humidity for extended periods of time. Even Siberia experienced it's first +30C temperatures lately (humidity was likely low). Things might be heating up a tad. The physiologists should prepare an LD₃₅ curve that shows lethal dry and wetbulb temperatures.

Maybe something to look forward to, and another issue to deal with.

dik's right (and wrong) at the same time. The models (and common sense) suggest that higher temperatures will result in more humidity, more moisture in the air, more rain overall. However, with changes in global climate means that SOME places will be drier as well.

BTW, this is the reason why the left change the terms on us. We're not calling it "global warming" any more. It's now called "climate change". So, if it's colder somewhere it's still "climate change". It allows them to cry that the sky is falling when virtually ANYTHING happens. Big storm.... It's climate change. A lack of storms, also climate change. A very hot summer, climate change. A very cold winter, climate change. Higher acidity in the ocean, climate change. Lower acidity in lakes or rivers, climate change.
