The highest man-made temperature was 520 million K. It was achieved by the JT-60 (JAERI Tokamak-60) reactor at the Naka Fusion Research Establishment, Nakamachi, Ibaraki prefecture, Japan, on 19 July 1996.\n\nThe lowest manmade temperature achieved so far is 450 picokelvin. It was achieved by a team of scientists at the Massachusetts Institute of Technologu in Cambridge, Massachusetts, USA

It does not increase the temp. of the earth. It changes the weather pattern of the earth. What increases the temp. is tall of the cows farting, cars, and global warming itself.

u can't have water upto 40 below zero!!!\nthe lowest temp(in centigrade) u can reach is -12 c \nthis is achieved by a process called super cooling\nin this the temp of the surroundings is controlled, and care is taken that the surface of the water is not disturbed\nsimilarly u can super heat water upto 137 c

There are many places on earth that are plenty hot - record-breaking hot. In fact, there's a good chance on the day this record-breaking temperature was recorded by a meteorological station in El Azizia in 1922 there were other places hundreds of miles away that were even hotter. In all likelihood, this record temperature has been exceeded since then in many places on earth, but we have no official records of the temperatures. It is important to note that when atmospheric temperatures are recorded it is not the surface temperature, where it can sometimes reach 150° F/ 66° C,

Drilling into the crust can not possibly affect the internal temp of the earth. We can NOT possibly dig deeper than that. easy. Next question.

Temperature is temperature no matter what elevation or altitude you are at - no need to know it.\n\nIf you want to correct station pressure readings to sea level for a weather station, then it may be helpful. The most practical and a reasonably accurate method though is to simply set your barometer several times (making small adjustments) to the sea level pressure using data from a good surface chart during daytime on a nice day with a weak pressure gradient (when it'll be very similar over tens of miles). Here is a good site for observations the past hour:\n\nhttp://www-frd.fsl.noaa.gov/mab/metar\n\nThey say data are experimental and not always accurate blah blah blah - but I never saw an error in METAR listings for any of the stations nor their locations - though you have to be able to read METAR reports. E-mail me if you wish regarding this.\n\nWhatever the case, Topozone is good if you want your elevation for any particular reason:\n\nhttp://www.topozone.com

True... the Dallol Depression in Ethiopia and Death Valley in California are the two hottest places on earth...\n\nBut the highest ever documented? El Azizia in Libya recorded a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922 -- the hottest ever measured and in Death Valley, it got up to 134 Fahrenheit on July 10, 1913.

There is no way to measure the temperature at the Earth's core directly. near the surface of the Earth, the temperature increases by about 1 degree Fahrenheit for every 60 feet in depth............The interior of the Earth reaches temperatures of 5650 ± 600

Read the real science - there are 3 metastable states of earths climate, all others are unstable. \n(1) lukewarm: like it is now\n(2) Ice-age: usually kicked off by over-heating the lukewarm\n(3) Ice-cube: Requires most land mass to be located along the equator\n\nWhat happens is it gets hot, really stormy, the clouds reflect off the light, underneath it snows, builds up ice pack, by the time the clouds dissipate the snow & ice can reflect just as well, and the energy balance equation for the earth adjusts so much less energy is retained.\n\nAbout 70,000 BC there was a super-volcano eruption.  It made sulfuric acid clouds, put dust from madagascar to greenland, made it rain very acid rain worldwide, increased the temperature of the entire oceans by 10 degrees Celsius, and kick-started the last ice-age.  In comparison the entire effect of man is less than 2 degrees celsius in the oceans.  My point: its going to take a lot more than the last 200 years of man to give a disturbance larger than what has happened in recent geologic history according to scientists.  NOVA had a great special on it.\n\nSo what if the Arctic melts?  The carbon that made the oil had to come from a very high density of living things, something that is made by dense jungles, not tundra.  According to geologists the Arctic being melted isnt a bad thing.  Nature is fine with it, isnt it?\n\nSo what if the Ocean temperatures rise by a few degrees?  They have been 5 times higher due to a single event according to geologists, and life got through it fine.  \n\nSome people say the end of fish is near, but they radically abused the math.  The power law is the worst fit possible for the data, and a exponential-polynomial fit is much much better, supporting a metastable transition.  \n\nGlobal warming or global freezing sells papers, but the people selling the idea are usually more interested in your money than in anything resembling long-term sustainability.  Their idea of sustainability is to treat humanity as something between cattle and a plague of locusts.  My personal opinion is that dehumanizing humanity and managing reproduction is a bigger sin that bad math and bad science.  Its evil.  Find a value system that treats humans like humans, and not animals.

Highest temp ever recorded was 136 deg. F at El Azizia (Libya) in 1922. This is not officially recognized by all.\n\nDeath Valley, CA, USA has the hottest temperature in the world at 134 deg. F.

I think its because you skipped science at school. The answers were mostly simple and logical.\n\nHow high is up? - As high as you want. I like the reference to upness in the best answer. Good word that.\n\nThe temperature question needs rephrasing. I think you need to use absolute zero as a reference. In which case the temperature is about -231.5 degrees F. This will feel a lot more than twice as cold though, since our temperature sensors in our skin don't work that way.

Antarctica is the coldest place on Earth. The lowest natural temperature ever recorded on Earth was -89.2 °C recorded in 1983 at the Russian Vostok Station in Antarctica. However, cryogenic labs have achieved much lower temperatures using artificial means. In 2003, Massachusetts Institute of Technology scientists cooled sodium to about 0.45 nanokelvins (–273.149 999 999 55 °C). Moving away from the Earth, the coldest temperature found in nature is the Boomerang Nebula, at about one kelvin, which is cooler than the cosmic microwave background radiation.

In order for the overall temperature on earth to remain constant, all the radiation that the earth receives from the sun should end up being reflected over a period of time back into space. This is radiation balance to the best of my knowledge. Otherwise, the planet would cook like an oven

There is no theoretical highest temperature, except that all matter would turn into pure energy at some point above 10^26 Kelvins. Beyond that, there is no absolute highest temperature.

Got to be honest. I became more and more confused about a topic that I used to understand so well with that first response. Although a lot of that is facts, it is overcomplicated at some parts and tough to get a hold on what is actually being described. No disrespect to rizzo though, I realise that everything he wrote is correct so he knows what he's talking about, I just think it would be hard for anyone else to.\n\nMaybe this description will be slightly less dizzying:\n\nAll heat is from the sun. Most of what comes from the sun is short-wave radiation, from 400nm down. Air is not heated very much from the sun, but the ground is. This is because the ground can absorb the short-wave incoming radiation, air cannot (well, only a little bit). The air is mostly heated by the longer-wave radiation that comes from the ground when it gets heated up, which heats the water molecules in the air (that's why humid regions get hotter than dry regions). \n\n*Note: Extremely dry air can be heated too, but that requires continuous exposer to sunlight. As soon as the sun is gone, it gets cold fast. Also it gets colder faster with altitude in dry regions.*\n\nAnyways. Up high, on top of being farther away from the ground, there is also less water molecules to absorb heat (and less molecules total to be heated up at all. So it absorbs less radiation. That is why it is colder. Simple. \n\nNo "adiabatic" mumbo jumbo. But adiabatic cooling is also simple. When air rises, the pressure on it decreases and it expands. The heat will be spread out over more volume, so the air will cool. This is the more complicated reason why the farther away from the ground you get, the colder the air is.\n\nAlso, there is something called an inversion. In this case, the air actually gets hotter as you go up. This happens when a warm air mass is forced up over a denser cold air mass because it is lighter. When this happens, the air is stable (it won't rise). This can result in people getting to choke on their own pollution for a couple of days because the crap they spew up in the air won't rise anymore. It's poetic.

http://www.badastronomy.com/mad/1997/hightemp.html\n====================================\nThis is actually not an easy question! It depends on what you mean by temperature. Here on Earth, in our cozy blanket of air at one atmospheric pressure, we think of temperature as how hot something is. But on a microscopic level, that really means how vigorously molecules and atoms are bumping into each other. The faster they move, the harder they bump, and the higher the temperature. \nHowever, have you ever wondered why water at 70 degrees Centigrade might scald you, but air at that temperature won't? Air is less dense than water, so it carries less energy total even if the temperature is the same. The atoms are jiggling just as fast, but there are fewer of them. \n\nI bring this up because there can be ridiculously high temperatures in the Universe, but they don't mean much! For example, the Voyager probe measured a temperature of over one billion degrees in the magnetosphere of Uranus. Imagine! But really what it was measuring were particles moving extremely quickly. If you stood (well, floated) in Uranus' magnetosphere, you wouldn't suddenly vaporize. On the contrary, you'd freeze! The particles may be very very hot, but there simply aren't enough of them for them to heat you up. \n\nSo to answer your question, probably the hottest temperatures reached in the Universe today are in the cores of supernovae (stars that explode), or possibly in the mysterious gamma ray bursters, extremely energetic explosions the cause of which no one knows. But the hottest temperature of all time would have been the Big Bang: since it had all the matter and energy squeezed into one point, it must have had nearly infinite temperature! \n==========================================\n\nhttp://www.phys.utk.edu/sorensen/pub/PAD_CV.htm\n\n Based on data from CERN in Switzerland we have finally been able to detect the emission of direct photons from heavy ion reactions. The implications of this discovery are huge. First of all: based on the slope of the transverse momentum spectrum we can deduce, that the photons are emitted from a fireball at a temperature above 300 MeV, which must be the hottest temperature ever measured of any object!! A temperature of 300 MeV correspond to a temperature of more than 5 trillion degrees on the Fahrenheit scale. More importantly, this discovery strongly suggests that the so-called Quark Gluon Plasma must have been created in the early stages of the fireball. Our discovery was prominently featured during the press conference at CERN in Spring 2000 and was mentioned in the front page feature in New York Times describing the potential discovery of the Quark Gluon Plasma at CERN.
