The Earth's average surface absolute temperature for the 1961–1990 period has been derived by spatial interpolation of average observed near-surface air temperatures from over the land, oceans and sea ice regions, with a best estimate of 14 °C (57.2 °F). [44] The estimate is uncertain, but probably lies within 0.5 °C of the true value. [44]
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
The sensors also deteriorate over time, and corrections are necessary for orbital drift and decay. [3] [4] [5] Particularly large differences between reconstructed temperature series occur at the few times when there is little temporal overlap between successive satellites, making intercalibration difficult.

Copernicus calculated that the global average temperature for 2023 was about one-sixth of a degree Celsius (0.3 degrees Fahrenheit) warmer than the old record set in 2016. ... Earth's average ...
The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
The world may have just broken the record for the hottest global average temperature ever recorded for the third time this week, according to data from the U.S. National Centers for Environmental ...
Summers can be hot in Death Valley, California. In fact, it has long held the title of hottest place on Earth. Especially on Sunday, August 16 and—again—on June 17, 2021.
Re changes to vertical axis: version 16's source states: "Annual global mean temperatures expressed as a difference from pre-industrial conditions. Four different data sets are shown - HadCRUT, NOAAGlobalTemp, GISTEMP, and Berkeley Earth - as well as two reanalyses - ERA5 and JRA-55.
