A.^ Height above sea level is the usual choice of definition for elevation. In terms of the point farthest away from the centre of the Earth, Chimborazo in Ecuador (6,267 m (20,561 feet)) can be considered the planet's most extreme high point. This is due to the Earth's oblate spheroid shape, with points near the Equator being farther out from the centre than those at the poles.
B.^ All temperatures from the World Meteorological Organization unless noted.
C.^ The former record of 57.7 °C (135.9 °F) recorded at Al 'Aziziyah, Libya on 13 September 1922 was ruled no longer valid by the WMO due to mistakes made in the recording process.[18]
E.^ Temperatures greater than 50 °C (122 °F) in Spain and Portugal were recorded in 1881, but the standard with which they were measured and the accuracy of the thermometers used are unknown; therefore, they are not considered official. Unconfirmed reports also indicate that a set of Spanish stations may have hit 48.0 °C (118.4 °F) during the 2003 heat wave.[19]
F.^ A temperature of −66.1 °C (−87.0 °F) was recorded at North Ice, Greenland on 9 January 1954. However due to unknown recording conditions it is not considered official.[20]
G.^ A temperature of 53.1 °C (127.6 °F) was recorded in Cloncurry, Queensland on 16 January 1889 under non-standard exposure conditions and is therefore not considered official.[21]
H.^ A temperature of −25.6 °C (−14.1 °F) is reported for Ranfurly, New Zealand having occurred on 18 July 1903. However, it is not listed by the WMO.[22]

Coldest and hottest inhabited places on Earth

Hottest inhabited place Dallol, Ethiopia (Amharic: ዳሎል), whose annual mean temperature was recorded from 1960 to 1966 as 34.4 °C (93.9 °F).[23] The average daily maximum temperature during the same period was 41.1 °C (106.0 °F).[24]
Coldest inhabited place Oymyakon (Russian: Оймякон), a village (selo) in Oymyakonsky Ulus of the Sakha Republic, the Russian Federation, located along the Indigirka River.[25] It has the coldest monthly mean with −50 °C (−58 °F) the average temperature in January, the coldest month.[26] Eureka, Nunavut, Canada has the lowest annual mean temperature at −19.7 °C (−3.5 °F).[27]
The South Pole and some other places in Antarctica are colder and are populated year-round, but almost everyone stays less than a year and could be considered visitors, not inhabitants.

Extreme ground temperatures

Temperatures measured directly on the ground may exceed air temperatures by 30 to 50 °C.[28] A ground temperature of 84 °C (183.2 °F) has been recorded in Port Sudan, Sudan.[29] A ground temperature of 93.9 °C (201 °F) was recorded in Furnace Creek, Death Valley, California, USA on 15 July 1972; this may be the highest natural ground surface temperature ever recorded.[30] The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C for dry, darkish soils of low thermal conductivity.[31]

Satellite measurements of ground temperature taken between 2003 and 2009, taken with the MODIS infrared spectroradiometer on the Aqua satellite, found a maximum temperature of 70.7 °C (159.3 °F), which was recorded in 2005 in the Lut Desert, Iran. The Lut Desert was also found to have the highest maximum temperature in 5 of the 7 years measured (2004, 2005, 2006, 2007 and 2009.) These measurements reflect averages over a large region and so are lower than the maximum point surface temperature.[28]

Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−136 °F) on 10 August 2010, at 81°48′S 59°18′E / 81.8°S 59.3°E / -81.8; 59.3. Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air temperature of −89.2 °C.[32][33]

Northernmost point on land Kaffeklubben Island, east of Greenland (83°40′N 29°50′W / 83.667°N 29.833°W / 83.667; -29.833)
Various shifting gravel bars lie further north, the most famous being Oodaaq
Southernmost point on land The geographic South Pole

The Gould Coast (84°30′S 150°0′WCoordinates: 84°30′S 150°0′W)[40] is the southernmost point of ocean while the southernmost open sea is nearby Bay of Whales at 78°30'S, at the edge of Ross Ice Shelf.[41]
