  2. Global surface temperature - Wikipedia

    en.wikipedia.org/wiki/Global_surface_temperature

    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]

  3. Atmosphere of Earth - Wikipedia

    The average temperature of the atmosphere at Earth's surface is 14 °C (57 °F; 287 K ... the Sun's rays pass through more atmosphere than normal before reaching your ...

  4. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Atmospheric temperature is a measure of temperature at different levels of the Earth's atmosphere. It is governed by many factors, including incoming solar radiation , humidity , and altitude . The abbreviation MAAT is often used for Mean Annual Air Temperature of a geographical location.

  5. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Geothermal gradient is the rate of change in temperature with respect to increasing depth in Earth 's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in ...

  6. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft), as obtained from the International Civil Aviation Organization (ICAO). The environmental lapse rate is the decrease in temperature of air with altitude for a specific time and place (see below). It can be highly variable ...

    International Standard Atmosphere. The International Standard Atmosphere (ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations. It has been established to provide a common reference for temperature and pressure and consists of ...

  9. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    In common usage, climate change describes global warming —the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate.
