I had read somewhere that this value is 130 °F at sea level (and thus the 134 °F one at Death Valley back in 1913 is suspect). Is there some paper that explains how this figure was derived?

Is Mt. Everest the highest point on earth.fresh_42 said:This is nonsense. Maybe the highest measured (56,7 °C on 7/10/13), but definitely not the highest theoretically possible. For one we have created much, much higher temperatures in the lab, and for two: just wait another two billion years and ask again. And if we continue to organize the planet as we do, Earth will become Venus like far earlier.
And measured ground temperatures are far higher.

Uh, I was referring to the highest meteorological temperature under today's conditions, not the highest that could be obtained under artificial conditions.fresh_42 said:This is nonsense.

That's not what your subject line said. As I think you can see from this thread, you need to be clear in your questions if you expect to get answers that tell you what you want to know.swampwiz said:Uh, I was referring to the highest meteorological temperature under today's conditions, not the highest that could be obtained under artificial conditions.
https://public.wmo.int/en/media/pre...rd-and-4th-hottest-temperature-recorded-earthAccording to the Weather and Climate Extremes archive, the hottest temperature ever recorded was in Furnace Creek, Death Valley, California at 56.7°C on 10 July 1913. The highest temperature for the Eastern hemisphere was set in July 1931 in Kebili, Tunisia, at 55.0°C. Some weather historians have questioned the accuracy of old temperature records. The WMO Archive for Weather & Climate Extremes is always willing to investigate any past extreme record when new credible evidence is presented.
Irrelevant. Please read the subject line of the OP (and I'd suggest reading the rest of the thread as well). This thread is not about the highest temperature OF the Earth, it is about the highest temperature ON the Earth.daniel dearment said:I would think the highest temperature of Earth would be 211 degrees F because at 212 the oceans would begin to boil.
I find it an interesting coincidence that @daniel dearment was correct about 212°F, but for the wrong reason.phinds said:Irrelevant.

That's not necessarily true, it depends on how you define temperature, which is an ensemble property.anorlunda said:The air temperature can not be infinite, but I see no way to pin it down to a defined number. Don't confuse unlimited with undefined.
Not sure what you mean 'on Earth'?swampwiz said:I had read somewhere that this value is 130 °F at sea level (and thus the 134 °F one at Death Valley back in 1913 is suspect). Is there some paper that explains how this figure was derived?
I saw the temperature 140 °F at Ft. Erwin, CA which is about 40 miles from Death Valley when I was there for part of my Basic Training in the Army. That was on the 3 mile long and 1 mile wide blacktop in the afternoon. The thermometer was in the sun. It was 125 °F in the shade when I arrived there. Our training for the 2 weeks I was there was before 10 AM and after 7 PM. 135 °F is not at all unusual on top of a haystack in Utah during midday.swampwiz said:I had read somewhere that this value is 130 °F at sea level (and thus the 134 °F one at Death Valley back in 1913 is suspect).

OK, I'll redo the question specifications.cmb said:Not sure what you mean 'on Earth'?
You seem to be measuring air temperatures, in which case you should be aware that the thermosphere is of the order of 2,000C during the day.
If you 'do' mean air temperature but exclude the thermosphere then you're being very arbitrary with your definition? What height is permissible as a measurement?
If you 'don't' mean air temperature but surface temperature, then you mean the surface of something, and as you will be sure to know the surface of things can get very very hot if they are not cooled by flowing air, you can cook an egg on a car bonnet left out in the Sun. In theory, with good insulation and no moving air, a surface could theoretically reach an equilibrium with the incoming photons, so maybe 5,000K?
Do you wish to revise any part of your question, at this point?
OmCheeto said:I can't remember the equations off the top of my head, but Wiki has a brief reference; "The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C (between 194 and 212 °F) for dry, darkish soils of low thermal conductivity."
The highest theoretical temperature that can be reached on Earth is known as the Planck temperature, which is approximately 1.416 x 10^32 Kelvin.
The Planck temperature is significant because it is the maximum temperature that can exist in the universe according to the laws of physics. It is also the temperature at which the four fundamental forces of nature (gravity, electromagnetism, strong nuclear force, and weak nuclear force) would merge into one single force.
No, the Planck temperature is purely theoretical and cannot be reached on Earth. It is so incredibly high that it is impossible for any physical object to reach this temperature.
The highest temperature ever recorded on Earth was 134 degrees Fahrenheit (56.7 degrees Celsius) in Death Valley, California, USA on July 10, 1913.
No, it is not possible for the temperature on Earth to ever reach the Planck temperature. The Earth's surface temperature is limited by the amount of energy it receives from the sun and the heat that is trapped in the atmosphere. The Planck temperature is trillions of times higher than the temperature at the center of the sun, making it impossible for Earth to reach this temperature.
